Unearth with Caution: The Art of Safe Digging in Construction

Introduction: Navigating the Subsurface Challenges

Excavation is a cornerstone of construction, allowing builders to create foundations, install utilities, and shape the built environment. However, the process of digging beneath the surface comes with inherent risks, demanding a delicate balance between progress and safety. This comprehensive guide explores the art of safe digging in construction, emphasizing the critical importance of precautions and methodologies to ensure the well-being of workers and the integrity of existing infrastructure.

1. The Importance of Safe Digging Practices

Safety is paramount in construction, and excavation introduces a unique set of challenges that must be addressed with precision. Unsafe digging practices can lead to accidents, damage to underground utilities, and costly delays. Recognizing the importance of safe digging is not only a legal and ethical obligation but also a strategic imperative for construction projects aiming for efficiency and success.

2. Understanding Subsurface Challenges

a. Mapping Underground Utilities: One of the primary challenges in safe digging is the presence of underground utilities. Gas lines, electrical cables, water pipes, and telecommunication cables crisscross beneath the surface, creating a complex network that must be accurately mapped before excavation. Failing to do so can result in catastrophic consequences.

b. Soil Conditions and Stability: The type of soil and its stability play a crucial role in excavation safety. Unstable soil can lead to collapses, posing significant risks to workers and nearby structures. Understanding soil conditions and implementing appropriate shoring and support systems is vital for safe digging.

c. Adjacent Structures: Proximity to existing structures introduces additional challenges. Excavation near buildings or other infrastructure requires careful planning to prevent subsidence or damage. The art of safe digging involves assessing the impact on adjacent structures and implementing measures to mitigate potential risks.

3. Precautionary Measures: Building a Foundation of Safety

a. Utility Locating and Mapping: Before any excavation begins, utility locating and mapping are essential steps. Utilizing modern technologies such as ground-penetrating radar and electromagnetic locators, construction teams can accurately identify the location of underground utilities, minimizing the risk of accidental damage during digging.

b. Site Surveys and Geotechnical Analysis: Conducting comprehensive site surveys and geotechnical analysis helps assess soil conditions and stability. This information informs the design of appropriate excavation support systems, such as shoring, underpinning, or soil stabilization techniques, ensuring a safe working environment.

c. Communication and Coordination: Effective communication and coordination among all stakeholders are critical for safe digging. Construction teams, utility companies, and local authorities must collaborate to share information, coordinate excavation schedules, and implement safety measures. Regular updates and clear communication protocols contribute to a safer work environment.

4. Shoring and Support Systems: Reinforcing Safety

a. Trench Shoring: In excavations where trenches are required, shoring systems provide critical support to prevent soil collapse. Various shoring techniques, including hydraulic shoring, slide rail systems, and trench boxes, are employed based on the specific requirements of the project and soil conditions.

b. Underpinning: Excavations near existing structures may necessitate underpinning to reinforce foundations and maintain structural stability. Underpinning methods, such as micropiles, jet grouting, or concrete underpinning, are employed to safeguard adjacent structures during excavation.

c. Slope Stabilization: In areas with sloping terrain, slope stabilization measures are implemented to prevent soil erosion and landslides during excavation. Techniques such as soil nailing, retaining walls, and erosion control systems contribute to the stability of the excavation site.

5. Technological Advancements: Enhancing Safety in Excavation

a. Remote Sensing Technologies: Advances in remote sensing technologies, including LiDAR and satellite imagery, have enhanced the accuracy of subsurface mapping. These technologies provide detailed information about the topography and existing utilities, aiding in the development of precise excavation plans.

b. Real-Time Monitoring Systems: Real-time monitoring systems offer continuous surveillance of excavation sites. These systems can detect ground movement, changes in soil conditions, and potential risks, allowing for immediate response to emerging safety concerns.

c. Trenchless Excavation Techniques: Trenchless excavation techniques, such as horizontal directional drilling (HDD) and pipe ramming, minimize surface disruption and reduce the need for extensive digging. These methods not only enhance safety by avoiding open trenches but also contribute to efficient and cost-effective construction.

6. Training and Education: Cultivating a Safety Culture

The art of safe digging extends beyond technology and methodologies—it encompasses the people involved. Training and education are essential components of cultivating a safety culture in construction. Workers must be equipped with the knowledge and skills to identify and respond to potential hazards, emphasizing the importance of a collaborative and vigilant approach to safety.

Conclusion: Excavating a Future of Safety and Progress

In conclusion, safe digging is an art that blends precaution, technology, and expertise to navigate the complexities of subsurface challenges. As the construction industry evolves, the emphasis on safety becomes increasingly integral to project success. By understanding subsurface conditions, implementing precautionary measures, leveraging technological advancements, and fostering a culture of safety through education and training, construction projects can unearth progress while ensuring the well-being of workers and the longevity of existing infrastructure. The art of safe digging is not merely a necessity; it is a commitment to constructing a future where progress and safety go hand in hand beneath the surface of urban development.

Re-using existing piles can result in set you back financial savings as well as reduction in program as well as reducing the ecological effect of a task. Strenuous screening is carried out to ensure that the heap is trustworthy and also can be re-used. Enlarged heads are an add-on to precast as well as CFA stacks that spread the load of a structure or embankment over a better area. This guarantees that raised loads can be put on the piles without the threat of the stack penetrating the slab or geo-membrane.

Driven Structures

Shaken stone columns are a ground enhancement method where columns of crude accumulation are put in soils with bad drainage or bearing ability to improve the dirts. In high latitudes where the ground is continuously icy, adfreeze piles are used as the key architectural structure method. The horizontal planet stress are focused on the soldier stacks because of their family member rigidity contrasted to the lagging. Soil motion as well as subsidence is decreased by maintaining the lagging in strong contact with the soil. A lot of installments can be finished in much less than a week, getting your job back on course. Generally, a single-storey expansion determining 6.0 m by 3.0 m using driven piles, can be completed within 2 to 3 days.

Deep foundations can be constructed out of hardwood, steel, strengthened concrete or prestressed concrete.

Their usage is also limited in houses in many nations.

After carrying out the initial tremie grouting, a stress grouting is adhered to concurrently with the training of the casing from the bond area.

Shotcrete Technology | Spar Geo Infra

Shotcrete is a process in which mortar or concrete is conveyed through a hose and applied pneumatically. The sprayed material when applied to the surface, fills the cracks and fissures, provide resistance to loose material from slope from falling. Shotcrete serve as protective layer on the slope surface as well as provide resistance against the failure when used with anchoring support systems. This helps in achieving high strength and low permeability.

The shotcreting process is carried out form the base of slope to upwards so as to reduce rebound rate during the application of shotcrete on the surface. The stabilization scheme for stabilization of slope using shotcrete can be designed and used with or without steel mesh. Design of shotcrete depends upon the purpose of project, design life, rock/soil strata.

There are two types of Shotcrete:

1. Dry-Mix 2. Wet-Mix

Dry-Mix Shotcrete The cementing material and aggregate are mixed in proper proportions, bagged in a dry condition and are transported right to a pneumatically operated gun to deliver a continuous flow of material through the supply hose to the nozzle. The nozzle’s interior is fitted with a water ring which uniformly injects water into the mixture as it is being discharged from the nozzle over the receiving surface.

Wet-Mix Shotcrete

The cementing material, aggregate, water and admixtures are properly mixed similar to what is done for conventional concrete. The mixture of material is supplied to the delivery equipment, like a concrete pump, which pushes the mixture through the delivery hose by positive displacement or by compressed air. Supplementary air is added at the nozzle to escalate the nozzle discharge velocity.

Advantages: Little or no framework required. Cost effective method. Ideal for irregular surface application. Material handling is easier. Excellent corrosion resistance.

Why Pilling Techniques In Australia Are Important.

Piling is mainly the support that is needed for any structure and thus is considered as the very basis of every construction project. There are different piling techniques to ensure that foundations are deep-set into the ground for stability. 

Since piling involves inserting large amounts of concrete, steel, or wood into the soil, safe and environmentally friendly techniques must be considered to avoid harming the earth and the environment in the long run. As such, it is essential to opt for pilling in Australia since the procedure is eco-friendly and safe piling techniques are applied.

Piling specialists available in Australia are always on the lookout for eco-friendly methods and materials that can ensure a sturdy and safe solution for both the earth and your structure. The use of an auger cast or CFA pile is one eco-friendly piling technique that involves drilling into the ground with a hollow-stemmed and continuous flight auger, without any casing. 

The cement grout mix is pumped down the auger's stem, and as the grout is pumped, the drill is slowly removed to transport the soil upward along with flights. The result is a shaft of fluid cement grout that arises to ground level. Reinforcement may be placed to support any load or weight through tripod piles, micro piles, soldier piles, suction piles, and sheet piles, depending on the architectural or infrastructure concept of the project.

Driven piles are known to be environmentally friendly, too. They are slender and long columns that offer support for effective resistance forces. Look for groundworks and piling specialists in Australia who can craft the driven piles into predetermined sizes and shapes, so they can be physically inspected before or during installation, which is possible via vibrating, impact hammering, or by simply pushing them into the soil.

 Environmentally friendly driven piles are made of natural materials that conform to the standards of ASTM. When manufacturing them, their quality must be consistent throughout the first to the last pile.

Importance of pilling techniques in Australia:

    • Saves the environment- Eco-friendly piling techniques will help in saving the surrounding.

    • They can help you save money in the long run, too. Driven piles, for instance, are usually cost-effective since you pay only for what you need without any hidden costs and surprise expenses related to clean-up. 

    • Installations typically do not produce spoils, so you do not have to worry about the disposal of contaminated or hazardous materials.

    • Ensures a sturdy foundation through the installation of heavy posts in the subsurface.

There are different types of deep foundation piling in Australia, and the micropile is one of them. They are deep foundations built with heavy-duty steel casings and threaded bars that are small.

The casing is installed using specialized drilling equipment and method. An all-thread bar serves as reinforcing steel in mini piling, and it is usually inserted in the micropile casing. 

In conclusion, opt for the pilling available in Australia since great techniques are applied during the process. This not only provides a sturdy foundation but also saves the environment through eco-friendly methods.

Factory Firm Foundations: The Use of Micropiles in Machine Installation

It’s a difficult decision: should I repair the broken machine in my factory or replace it? It really needs to be replaced, but I can’t afford the downtime. Besides, I don’t want to mess with the entire foundation or damage any of the other machines around it. Read on to find out how micropiles are the solution!

  Our goal at TEI is to utilize new technologies to create stronger, safer foundations worldwide – including our own. At our 28,000 square foot facility in beautiful Montrose, Colorado, our process is ISO 9001:2015 certified and we do everything by the book – except think. When it comes to thinking, brainstorming, coming up with innovative ideas, we throw the book away completely. Our engineers are continually finding creative and efficient new ways to solve old problems.

 TEI rock drills are highly regarded and sought-after all over the world for a variety of complex and interesting projects. Brokk’s demolition robots fitted with our TE160 hydraulic drifters help to reduce operator fatigue and allow access to tightly confined spaces, for example. Our equipment has been used to install ground loops for geothermal heat pumps, and for various applications by the US Military. TEI rock drills were used in the creation of the Solana Solar Generation Plant in Arizona, the Panama Canal expansion project, and the ongoing construction of Crazy Horse Monument in South Dakota. Not to mention thousands of road construction, building construction, demolition, tunneling, mining, and rock quarry projects from Canada to New Zealand since we built our first drill in 1980.

 But what does a company like TEI do when we need to work on our own foundation? Who doctors the doctor? Who teaches the teacher?

 A few years ago, when a CNC (Computer Numerical Control) machine in our factory needed to be replaced, we knew the best way to ensure a solid foundation was by using our own equipment to install micropiles. It worked so well that we’ve done it five times since, and plan on doing so again.

 We rely on CNC machines, such as milling machines and lathes, to accurately and efficiently assist in creating our powerful precision drills. These machines can weigh in excess of 30,000 pounds and are in motion much of the time – motion that can potentially vibrate the machine out of place if installed incorrectly. An unsuitable foundation is guaranteed to cause leveling and alignment issues, rapidly deteriorate spindle bearings, ball screws, and other machine parts as well as overall machine life, and contribute to final product inaccuracy.

 The necessity to replace our machinery comes around often, as we upgrade our equipment quite regularly. Most recently, we purchased a CMM, or Coordinate Measuring Machine, for purposes of quality control. This big, heavy machine needs to be installed according to very exact specifications in order to ensure its accuracy. Depending on who you ask, there are a few different options for doing this in a pre-existing space.

 The most widely-used option would be to completely gut the floor structure and then pour a very thick (think feet – not inches) layer of concrete. This can take a few days, and in a factory setting where time is money, this is an expensive option. You also run the risk of the concrete moving or cracking; even the smallest air pocket can lead to disaster. This is often countered with the addition of a large steel plate or several smaller ones to spread the load, but steel slides on steel and will create more problems over time.

 Installing micropiles in this situation will alleviate all of these issues. It’s quick and unobtrusive. Downtime is minimal. And your foundation will last for many years without breaking down.

 “Cement can move, piles will stay,” says Bob Foreman, TEI’s Service Manager. “The key is to figure out exactly where the feet of the machine will sit and put piles in those strategic locations. Then you don’t end up with a great deal of stress on just a little bit of surface of the cement.”

 Micropiles – sometimes referred to as minipiles, pin piles, needle piles, and root piles – are extremely durable elements used in the construction and maintenance of deep foundations for many structures, and to prevent or control ground degradation due to normal wear-and-tear as well as disturbances such as earthquakes and landslides.

 Composed of high-strength, small-diameter steel casing and/or threaded bar, rebar, and grout, micropiles can range in diameter from 3-12 inches, extend to depths of 200 feet, and achieve compressive capacities of over 500 tons depending upon the size used and the soil profile.

 For the majority of building and repair projects, conditions are not ideal. Often, soil is not just soil: it’s mixed with construction debris or contains many different sizes and types of rock. Dense layers can be found over thinner, weaker layers. If other structures are close by, the ground may be unstable, or access could be limited. In these and other variable conditions, micropiles are a cost-effective solution to strengthen a deteriorating foundation or lay a new one.

 There are different kinds of piles suited for specific needs. Generally, an all-thread reinforcing bar is inserted into the micropile casing and then cement grout is pumped inside while drilling. This simultaneous drilling and grouting technique, called the injection bored method, is unique in that smaller equipment can be used, often at lower cost, and access to tighter working spaces is possible.

 The finished micropile enhances stability by transferring the load to more competent ground, or in rocky areas, to the rock itself. It’s much quicker and quieter than other techniques, it is completely vertical and therefore less obtrusive, and it’s adaptable to many different kinds of equipment.

 “Micropiles have allowed us to place and replace our machinery without constantly having to modify our building’s foundation,” shares Glenn Patterson, TEI’s Vice President and International Sales Manager. “Different load sizes are required for the various sizes of machines used in manufacturing. Exclusively using the hollow bar injection method means we are able to design each set of piles specific to each individual machine and allows us to keep our factory operational during the installation process.”

 Correct installation is every bit as critical as correct selection of machines for your factory or machine shop, whether you’re building a brand-new facility or retrofitting an old one. For a machine to perform successfully, the foundation on which it rests must be precise. There can be no compromises. As you can see, installing micropiles with TEI drills is the best way to do this.

 A few years ago, when a CNC (Computer Numerical Control) machine in our factory needed to be replaced, we knew the best way to ensure a solid foundation was by using our own equipment to install micropiles. It worked so well that we’ve done it five times since, and plan on doing so again.

 We rely on CNC machines, such as milling machines and lathes, to accurately and efficiently assist in creating our powerful precision drills. These machines can weigh in excess of 30,000 pounds and are in motion much of the time – motion that can potentially vibrate the machine out of place if installed incorrectly. An unsuitable foundation is guaranteed to cause leveling and alignment issues, rapidly deteriorate spindle bearings, ball screws, and other machine parts as well as overall machine life, and contribute to final product inaccuracy.

 The necessity to replace our machinery comes around often, as we upgrade our equipment quite regularly. Most recently, we purchased a CMM, or Coordinate Measuring Machine, for purposes of quality control. This big, heavy machine needs to be installed according to very exact specifications in order to ensure its accuracy. Depending on who you ask, there are a few different options for doing this in a pre-existing space.

 The most widely-used option would be to completely gut the floor structure and then pour a very thick (think feet – not inches) layer of concrete. This can take a few days, and in a factory setting where time is money, this is an expensive option. You also run the risk of the concrete moving or cracking; even the smallest air pocket can lead to disaster. This is often countered with the addition of a large steel plate or several smaller ones to spread the load, but steel slides on steel and will create more problems over time.

 Installing micropiles in this situation will alleviate all of these issues. It’s quick and unobtrusive. Downtime is minimal. And your foundation will last for many years without breaking down.

 “Cement can move, piles will stay,” says Bob Foreman, TEI’s Service Manager. “The key is to figure out exactly where the feet of the machine will sit and put piles in those strategic locations. Then you don’t end up with a great deal of stress on just a little bit of surface of the cement.”

 Micropiles – sometimes referred to as minipiles, pin piles, needle piles, and root piles – are extremely durable elements used in the construction and maintenance of deep foundations for many structures, and to prevent or control ground degradation due to normal wear-and-tear as well as disturbances such as earthquakes and landslides.

 Composed of high-strength, small-diameter steel casing and/or threaded bar, rebar, and grout, micropiles can range in diameter from 3-12 inches, extend to depths of 200 feet, and achieve compressive capacities of over 500 tons depending upon the size used and the soil profile.

 For the majority of building and repair projects, conditions are not ideal. Often, soil is not just soil: it’s mixed with construction debris or contains many different sizes and types of rock. Dense layers can be found over thinner, weaker layers. If other structures are close by, the ground may be unstable, or access could be limited. In these and other variable conditions, micropiles are a cost-effective solution to strengthen a deteriorating foundation or lay a new one.

 There are different kinds of piles suited for specific needs. Generally, an all-thread reinforcing bar is inserted into the micropile casing and then cement grout is pumped inside while drilling. This simultaneous drilling and grouting technique, called the injection bored method, is unique in that smaller equipment can be used, often at lower cost, and access to tighter working spaces is possible.

 The finished micropile enhances stability by transferring the load to more competent ground, or in rocky areas, to the rock itself. It’s much quicker and quieter than other techniques, it is completely vertical and therefore less obtrusive, and it’s adaptable to many different kinds of equipment.

 “Micropiles have allowed us to place and replace our machinery without constantly having to modify our building’s foundation,” shares Glenn Patterson, TEI’s Vice President and International Sales Manager. “Different load sizes are required for the various sizes of machines used in manufacturing. Exclusively using the hollow bar injection method means we are able to design each set of piles specific to each individual machine and allows us to keep our factory operational during the installation process.”

 Correct installation is every bit as critical as correct selection of machines for your factory or machine shop, whether you’re building a brand-new facility or retrofitting an old one. For a machine to perform successfully, the foundation on which it rests must be precise. There can be no compromises. As you can see, installing micropiles with TEI drills is the best way to do this.

Factory Firm Foundations: The Use of Micropiles in Machine Installation

It’s a difficult decision: should I repair the broken machine in my factory or replace it? It really needs to be replaced, but I can’t afford the downtime. Besides, I don’t want to mess with the entire foundation or damage any of the other machines around it. Read on to find out how micropiles are the solution!

    Our goal at TEI is to utilize new technologies to create stronger, safer foundations worldwide – including our own. At our 28,000 square foot facility in beautiful Montrose, Colorado, our process is ISO 9001:2015 certified and we do everything by the book – except think. When it comes to thinking, brainstorming, coming up with innovative ideas, we throw the book away completely. Our engineers are continually finding creative and efficient new ways to solve old problems.

  TEI rock drills are highly regarded and sought-after all over the world for a variety of complex and interesting projects. Brokk’s demolition robots fitted with our TE160 hydraulic drifters help to reduce operator fatigue and allow access to tightly confined spaces, for example. Our equipment has been used to install ground loops for geothermal heat pumps, and for various applications by the US Military. TEI rock drills were used in the creation of the Solana Solar Generation Plant in Arizona, the Panama Canal expansion project, and the ongoing construction of Crazy Horse Monument in South Dakota. Not to mention thousands of road construction, building construction, demolition, tunneling, mining, and rock quarry projects from Canada to New Zealand since we built our first drill in 1980.

7 Ways On How To Repair The Foundation of Your Home

Nothing stresses a home owner than finding cracks in his floor or even the mere idea that his house will be coming down real quick. Building or buying a house is a pretty huge investment and this calls for proper maintenance. It is common for objects to deteriorate with time and a house being an object, it is prone to this. This could be the effect of ice, poor soil compaction, plumbing leaks among others. Worry not for foundation problems can be repaired.

To solve foundation problems, one first needs to understand the structure of the foundation. Slab foundations and pier or beam foundations react differently to foundation movement. Also repair of houses with basements would be different from the normal one. Below we discuss on seven ways on how to repair foundation problems:

1. High density polyurethane foam.

Technicians inject the foam in a checkerboard grid approximately six foot on center in the affected area. It is relatively cheap and repairs the problem faster. It is important to perform plumbing tests prior to the foam injection to ensure there are no leaks and the foam, therefore, would not leak into the water.

– This method is used where the foundation is concrete and what it typically does is that it seals a foundation crack against water entry.

– If you suspect that water leaks are the root cause of your foundation problems, you can contact a plumber to fix the issue.

– If you live in an area that rains a lot, it is important to have a foundation drainage system, or even go the extra mile and install a surface drain, moves a lot of water preventing accumulation of water. Or use of a French drain which redirects smaller amounts of water.

2. Steel piers.

Steel piers take less time and disturb less landscape, a proven underpinning solution for foundation repair.

Works best on foundation settling this is the case where one side of your house is lower than the other. If so, your foundation may need to be lifted and interior or exterior piers installed. These are placed around the perimeter of your foundation in order to raise it or else installed in the interior of your structure. Repair as soon as possible for what might start as only a small dip on the side of the house might end up being a very large problem. Cracks resulting from foundation problems are generally vertical. Professional foundation repair service that AbryBros provides would solve this problem.

Steps during installation of steel piers;

i) Ground is excavated for installation of piers around foundation.

ii) Foundation bracket would be mounted for the piering system.

iii) Installation of the push piers.

iv) Weight of structure transferred to the steel piers.

3. Soil Nailing

This involves strengthening the soil to give it more stability. This is done by hammering steel bars into the soil.

Steps involved;

i) Drilling into the soil. Where “nail” would be placed.

ii) Depth of the hole is measured.

iii) Nail is inserted into the drilled hole.

The soil nails are placed in an evenly spaced geometric patterns and they develop the pullout resistance. The geometric system of soil nail placement creates an internally reinforced soil mass that is stable.

Majority of foundation problems are caused by soil failure and stabilizing the soil therefore is more than an effective method.

4. Helical piers.

Work well for exterior foundation repair and interior slab repairs.

– Used especially when it is necessary to resist a tension or a compressive force.

– Helical piers look like a large screw. They are used for extra support to porches, steps and chimneys.

– They are a permanent solution to foundation problems.

– Can be used in any type of weather and can even support structure on weak or wet soil.

Helical plates welded to shaft. Plate diameters increase from bottom of the shaft upward. The plates may end up with a pier cap embedded into a concrete foundation.

5. Concrete pier foundation repair.

This was originally preferred before the invention of hydraulic driven steel pier. They are a more permanent solution to foundation problems.

Most expensive mode of repair. Though first time installation is cheap.

They can be in two forms:

a) Pressed concrete pilings – The concrete has already being cured and only involves installation. At time use of a steel, the leader is used to achieve greater depth while pouring water. Preferred on repairing the foundation.

b) Poured concrete piers. The piers are drilled up to about ten feet. Cure time before foundation leveling is 10 days.

6. Micropile underpinning.

This is the use of deep foundation friction piles constructed using high strength steel casings. This enables the transfer of some of the pressure put on them to the soil around them. The friction creates an adhesive effect where the pile and soil connect.

Steps involved;

i) Creating small diameter drilled and grouted friction piles.

ii) Installation of hollow bars via injection bored method.

iii) Pumping hollow bars with a cement grout mixture.

iv) Anchor drilled to grout

7. Carbon fiber strips

Average repair typically takes two to three days. Has incredible strength. Can be painted over hence low visibility.

May be for repair on walls with minor cracks or those that have bowed inward.

– Work best on concrete walls.

– Paint should be removed where the straps are to be set.

– Should not be placed apart more than four times the thickness of the wall.

The main problem of using the carbon fiber straps is that it doesn’t limit the movement of the wall below or above where straps are placed.

Conclusion:

In theory, repairing a foundation is quite simple as it involves lifting the house, replacing the old foundation with a new one and letting the house rest on the new foundation. This is not the case practically though as it involves a lot of factors, engineering data and study. Remember that foundation repairs need to be tackled by experts. This might turn out costly. Ask for cost estimate from the contractors and you can compare with those of different foundation repair companies. Look for ones with warranties as this would not have a cost implication in the future should the problem arise once more.

Upgrading Power Transmission Lines To Higher Voltage With Existing Infrastructure

Due to increasing urbanization and industrial growth, energy consumption has gone up in Tier I and Tier II cities in India. The rising population, along with the government’s focus to provide uninterrupted electricity to all homes by 2019, is projected to increase electricity consumption five to six times between 2014 and 2030.

 Over the last few decades, India has witnessed a steep rise in generation capacity. With the government’s efforts, even if half of the planned renewable capacity gets installed by 2022, the generation would certainly match the nation’s requirement.

Get More Detail at electrical power cable

However, the key to this fulfillment will be to match generation capacity addition with adequate power transmission and more importantly, intrastate transmission and the sub-transmission network. This network must be made available to enable the downstream to the load centers around densely populated urban areas of important states and industrial areas.

Under the 13th five-year plan, high capacity transmission corridors comprising 765 kV AC and 800 kV High Voltage Direct Current (HVDC) system have been planned to strengthen the national grid. It is estimated that 13,000 MW of HVDC systems will be required for grid expansion, but with growing demand, this itself is projected to grow to 15,000 MW under the 13th five-year plan. Most transmission networks in India had been built to handle a specific amount of power flow. With increasing load, they’re ill-equipped for higher power flow, and now need up gradation to better transmission capabilities.

Get More Detail at power transmission in India

This transition traditionally requires building additional transmission capacity by reinforcing the existing infrastructure, which is currently being done in the one or more of the following ways:

Building additional circuits or towers

Most of the current structures, however, aren’t designed to accommodate additional circuits.

Constructing new parallel transmission lines

However, rapid urbanization, escalating land costs and right-of-way (ROW) challenges to make this option prohibitively expensive. A right-of-way, that involves permission for additional ground space, can take several years to negotiate in addition to the time needed to upgrade to higher voltage transmission. Additionally, approvals for adding lines are difficult with today ’s environmental concerns due to depreciating forest and agriculture cover.

                   Get More Detail at aluminium conductor

Replacing existing conductors with conventional conductors of higher size

This would require tower replacements because of the additional structural loading and relative condition of the existing structures. Thermal sag associated with the conventional conductors is a concern too.

Updating the existing transmission lines with reconductoring

This method is a quick-fix arrangement and applicable to only short stretches within the network to enable decongestioning.

The method also leads to high losses in the stretches thereby creating voltage drops and system imbalances which is why a wide scale adoption is not possible by transmission planners.

The challenge today is to reduce the footprint of transmission corridor upgradation while increasing the transmission capacity multifold. Increased capacity without the need to reinforce existing infrastructure translates to greater profitability and lower transmission losses, therefore improving life-cycle costs compared with conventional line upgradation projects that often overrun, thereby increasing costs.

Fortunately, it is possible to upgrade transmission lines and substations to higher voltages without having to replace or reinforce the existing power structures. The upgradation challenges can be overcome with a modern cost-effective approach that provides an ideal solution with respect to grid stability and widespread adoption for getting up to 12 times the existing power throughput. Let’s understand this approach in detail.

Using narrow base tower which has lower height, narrower base, as well as lower weight as compared to a  standard tower maintains the tower footprint within the existing ROW requirements and saves significant costs and time.

For example, upgrading a line from 66KV to 132 KV requires ROW to be increased from 18 m to 27 m. With compact towers, this effective 33% reduction in ROW typically results in a cost- savings of up to Rs. 1cr/Km and saves a timeframe of 6 months to 1 year since no additional ROW approval or forest clearance is required.

         Get More Detail at transmission line company in india

Monopoles (single poles) can mitigate space constraints related to traditional poles that stand on 3-4 poles.

Use of Micropiles reduce excavation effort and time as well as tower foundation footprint (by10-20%) and adds to tower stability.

HTLS (High Temperature-Low Sag) conductors can carry more current per sq.mm than conventional ACSR (Aluminum Conductor- Steel Reinforced) conductor.

The power losses of the HTLS  conductor are 20% to 25% lower as compared with the conventional conductor.

HTLS operate at much higher temperature ranges (150-2500C) than ACSR (1000C), which increases the power transmission throughput to almost twice the current capacity.

Additionally, HTLS conductors have low thermal expansion in the temperature range.

The low sag feature also facilitates a reduction in tower height, which helps overcome ROW issues,as explained before.

Usage of a mobile substation at suitable strategic locations results in zero/minimal shutdown during the time upgradation is being carried out, thus resulting in higher grid reliability.

Sterlite Power is India’s leading integrated power transmission developer and solutions provider, which has been able to demonstrate this approach that tackles the key constraints of time, space and capital in voltage upgradation. Sterlite power has carried out comprehensive feasibility studies for voltage upgradation across numerous states in India and has proposed cost-effective solutions with the approach mentioned above.

India is the third largest producer of electricity in Asia, and its generating capacity is continuously growing. The distance between generating stations and load centers is increasing day by day. A huge transfer of power from generating plants to load centers at a long distance will require significant line upgradation and adding additional infrastructure will not be a feasible solution to go forward.

Access to power has the potential to change the lives of millions, by bringing about a transformation in the local economy, and with it, the country as a whole. The countrywide power transmission upgradation, however, will require a coordinated effort by government and various power transmission solution providers to solve the toughest challenges of energy delivery.

Macropiles, ultra-high-capacity micropiles, are deep foundation elements constructed using steel pipe. Typically, the pipe is advanced using a drilling technique to the design depth. In cases where the drill hole remains open without casing, an open hole can be advanced to the bearing depth and the pipe subsequently installed. Reinforcing steel in the form of all-thread bar or concentric pipes is inserted into the pipe. High-strength cement grout is then pumped into the pipe or pipes by tremie. The pipe may terminate above the bond zone with the reinforcing steel extending full depth. The finished foundation element resists compressive, uplift and lateral loads. The technique has been used to support buildings and bridges.

National Corvette Museum (No. 3)

GM began production of the esteemed Corvette in Bowling Green in 1981, and the facility has remained the exclusive home of the Corvette for over 30 years. Known around the world as America’s sports car, the Corvette exemplifies the definition of innovation. The Corvette is the world’s longest-running, continuously produced passenger car. When the first Corvette rolled off the line over 60 years ago, it was born an icon.

Corvette didn’t always call Kentucky home, however. In 1953, the first 300 were built by hand in Flint, Michigan, just after General Motors unveiled the Corvette as a “dream car” in the Motorama show in New York’s Waldorf Astoria hotel. The following year, production moved to St. Louis. In June of 1981, Corvette production transferred from St. Louis to Bowling Green, Kentucky.

On February 12, 2014, a sinkhole opened under the floor of the Skydome area of the museum at around 5:44 AM local time, causing a portion of the floor to collapse. Kentucky is one of the many states that is notable for having karst topography. Karst topography is the landscape that is formed from the dissolving of rocks such as limestone. In the museum's case, the sinkhole was caused by the dissolving of the limestone in the ground which caused pockets to open underneath the surface. Eventually, the weight of the building caused the top layer of soil to collapse. Eight rare and one-of-a-kind Corvettes, portions of the display stands and rails, large concrete floor slabs and dirt fell into the sinkhole, causing serious damage to some of the Corvettes. The Corvettes involved have an estimated value of a million dollars.The remaining 20 cars in the Skydome were immediately removed from that area. Between March 3, 2014 and March 6, 2014, 5 of the 8 Corvettes were recovered from the sinkhole. The spire area of the Skydome is being reinforced before work starts on removing the final three buried cars. Multiple multigravity tests were done to insure that another sinkhole wasn't present or in the making. The results came back clear which allowed for the construction work to begin. For added precaution, micropiles, or systems of steel rods, were inserted into the ground before the concrete was repoured to help give the building more support. The museum reopened the day after the sinkhole appeared.

The museum also sponsors the Corvette Hall of Fame for individuals who have been involved with the Corvette automobile and made significant contributions in their respective fields. Each year, between two and four persons are inducted into this select group.

WHY DO YOU NEED MICROPILES?

Micropiles are generally used when there are difficult ground conditions, such as natural or man-made obstructions, sensitive ground with adjacent structures, limited access/low headroom and/or karstic geology.  They are commonly used to replace deteriorating foundation systems, for the renovation of structures, to support structures affected by adjacent construction, for seismic retrofitting or in-situ reinforcement including embankment, slope and landslide stabilization.
