An aluminum trench shoring system involves bracing the walls in a trench to prevent it from collapsing. This is a safer approach than shielding which is only designed to protect workers if collapse occurs. Aluminum trench shoring system is used when the ground is unstable. With their spring mounted flexible spindles, the trench shoring boxes can be installed with the “cut and lower” method. The range differs with regard to the thickness of plates and the safe working loads.

When it comes to construction projects, employee safety is always the number one priority. One of the most dangerous situations on any construction site is when workers are working in a trench, which can sometimes be several feet deep and in some cases many miles long. The biggest danger in these jobs is the walls caving in, trapping the workers under dirt and other materials. To make sure this doesn’t happen, companies today use a variety of equipment designed to make most any job safer.

Hydraulic Aluminum Trench Shoring System

Depending on the type of trench and its size, many different types of equipment can be used. Three of the most popular methods involve hydraulic shoring, soldier boarding and beam and plate. Hydraulic shoring uses a combination of hydraulic pistons and either steel plates or heavy plywood to shore up the trench. The plates or plywood are put into place, then the pistons are positioned and activated until they are pressing against the walls, creating a safe and secure work environment.

The beam and plate method involves using steel beams that are driven into the ground, which is followed by inserting steel plates amongst them to shore up the trench walls. On some jobs, wooden planks are used in the place of steel plates. While most people assume trenches are simply done to install pipes or other materials below ground, there are many other types of trenches dug to install such things as manholes. For these trenches, it’s just as important to ensure they are shored up in a safe fashion.

Some of the latest innovations in making these trenches safer involve using fin form material to take advantage of the pressure put on trench walls by the surrounding ground. Rather than making trench walls that are straight, fin form walls are angled slightly when first put into the ground. However, they then use the pressure exerted on them by the surrounding ground to bow out and become straight, thus creating a very tight fit that will almost never waver and collapse. These are used quite often in manhole construction, when spaces can be tight and narrow and the threat of collapse very high.

Tell Me About Trench Box Excavation

Trench Box Excavation | Kundel Steel Trench Box on Trailer

A trench box excavation is common at many construction sites and is considered one of the most dangerous construction operations. Digging a hole in the ground seems simple but it is estimated that over 100 deaths per year occur due to the cave-ins and other excavation hazards. Digging can be a major cause of concern unless you know proper techniques and the rules for excavation and trenching. Never dig until you know it is safe.

OSHA regulation applies to all open excavations made in the earth service and requires workers in trenches and excavations be protected from the hazards that can occur during the operation. Prior to any excavation for trench work, the OSHA requirements should be reviewed and followed. Companies are responsible for knowing and following current federal state and local laws, implementing and effective help and safety program and insuring all affected employees work safe and follow the rules and regulations.

By definition a Trench Box Excavation is considered an excavation but there are differences between the two types have opening, an excavation is any man-made cut, cavity, trench or depression in an earth surface formed by earth removal. A trench is described as a narrow excavation made below the ground that is deeper than it is wide, trenches can be up to 15 feet wide.

Here is break down of trench box excavation processes:

  • Pre-excavate approx. 1.5 m depending on the stability of the soil; the Box-element is lowered into the pre-excavated trench,
  • Excavation is continued. A maximum of 0.5 m is advised, depending on the stability of the soil.
  • Both sides of the Box are pushed independently.
  • When both sides are lowered, excavation will continue.
  • Excavation is continued. A maximum of 0.5 m is advised, depending on the stability of the soil.
  • Both side of the Box are pushed independently.
  • After reaching full depth, pipes can be laid.

The most feared of all the hazards is the possibility of a cave-in. all excavations are hazardous because they are inherently unstable. Workers can be seriously injured or killed if the sides of a trench collapse. Unsafe trenches are the major factor in many trenching hazards. Trenches don’t have to be deep for accidents do occur. Serious injuries are also possible in shallow trenches that are less than five feet deep. Cubic yards of dirt can weigh up to 2700 pounds and are capable of moving a 25 feet per second. A cave in makes very little noise and gives very little warning. Prior to the collapse, some causes of cave-ins include:

  • vibrations from equipment or traffic in the area

What Exactly is a Shoring System

Shoring System

A shoring system is used to describe a system that helps retain earth, water and all adjacent structures present during the period an excavation is required. This process used in supporting buildings, structure, vessel or trench with shores or props while alterations or repairs takes place or when there are signs of danger of collapse. Shoring systems usually come from timber or metal props. A Shoring system could be vertical, horizontal or angled. Designing a shore could be very complicated. Here the designer has to face the challenges of so many unknowns and other circumstances that will affect the excavation shoring system. There are two major trenching methods that must be used during excavation: Earth Retention Shoring System which supports the wall of the earth during excavation and to support trench safety equipment which is the internal and external bracing that helps protect the earth retention system.

The process of taking up detailed calculation for both Shoring Systems is always very tedious and time consuming especially when the parameters used have to be changed. Also many new software programs which is being used does not include an integrated platform of structural and geo-technical analyses required for the design of Shoring System excavations. Due to this, the designer will have no other alternative than to use several other software programs to analyze the excavation and structural systems separately. Without including finite elements analysis, there are only few only few theoretical solutions that can be used in calculating lateral soil pressures from complex surface profiles. The designer will also have to save the different stages of the same excavation process with different file names. As a result of this, the whole excavation process becomes more complicated and time consuming. A professional will address all these issues and solve the problems using integrated structural and geo-technical platform for deep excavations. A shoring system is usually designed using both non-linear and traditional method of analyses. While it is known that traditional method of analyses have several limitations in accurately getting the real behavior, they are very useful in framing the problem and providing back-check for more rigorous finite element methods.

Various Types of Shoring System

Shoring system could also be done by the assembly of vertically oriented steel wide flanges covered in a cylinder of concrete arranged every 6-8 feet on in a straight line referred to as piles. Wood boards which are referred to as lagging are also arranged horizontally from one wide flange to the next and letting the whole assembly hold back earth on one side which will lead to a vertical cut on the other side. The main purpose of the shoring wall is to be the retaining wall even though the physics and construction methods are different. On a residential project, the height of shoring ranges from 6-12 feet while commercial projects uses shoring techniques that goes way beyond that range to a much deeper level using tie-backs. These shoring walls could be either temporary or permanent. A temporary application is usually supplemented with concrete walls when the earth has been properly retained. Shoring system is known to be very effective when two criteria are present on a site. It is necessary for a flat ground to be built on and also for the proximity of the building footprint to an existing structure. Cutting back and retaining the earth is needed for a flat and build-able ground. There are several ways this could be done. But a concrete retaining wall requires a large amount of space for it to be done. While building a framework for concrete footing and walls, the surrounding earth is required to be temporarily removed (usually about 45 degree angle) on both sides of the wall in other to make the space accessible. If this structure is located very close to an existing structure, the required space for excavation is then prohibitive. A shoring wall requires just a few inches while the concrete retaining wall needs few feet’s.

Despite the growth in the construction shoring techniques, engineers and Shoring System contractors still do face a lot of challenges builders faced in the past. The design and building of these shores could be more complicated due to the soil structure, depth of the cut and also the ground water, seismic loads, vibrations, weather condition, superimposed loads and adjacent construction. Properly designed and constructed excavation system is needed when excavation is being done in wet soil, sandy soil or areas that have been previously back-filled due to instability. Hard rock can also be hazardous to excavate. A Shoring System engineer will have to guard against an unstable excavation bottom especially when this is below water level. Some known permanent and temporary shoring system are steel sheet piling, soldier piles and lagging, jet or chemical grouting, secant or tangent piles and soil walls. To provide lateral support of sheeting and shoring system, anchors and bracing is used. A circular shoring system is designed as a compression ring to access shafts for tunneling and trench-less construction to resist loading. It is required that during construction Shoring System for excavations, an open extended period of time is needed for protections from weather conditions.

Steel trench shoring is the process of bracing the walls with steel to prevent it from falling apart. Here, steel beams are forced into the ground and steel plates are slid in among them. Shoring is designed to prevent collapse or possible falling apart of a structure. This process is highly recommended by most professional who agree that this is the safest approach in protecting workers during threatening operations that requires caution. Steel trench shoring offers maximum support for the life of the trench. They also help to avoid fines for excavation safety. This method helps save time by preventing water and other utility lines which are beneath the surface. They are also a great way to boost employee morale due to the fact that they make them feel safer while working on the site.

Steel Trench Shoring | Trench Safety Equipment

When service providers as well as communities face excavation obstacles that are beyond the abilities of their own fleet trench safety equipment, they have to rely on rental devices to complete the voids. Experienced shoring specialists must have the ability to address any excavation as well as security disputes by taking care of problems encountered on the job site; and even it is never ever a one-size-fits-all remedy. To properly offer your consumers’ trench shoring requirements, you should obtain as much information as feasible from the service provider or municipality’s marked safety and security official or design team before suggesting a steel trench shoring system. The complying with are some crucial points to think about when creating a safe and also suitable shoring system for a particular excavation job.

Steel trench shoring is a safety system that uses structural participants or hydraulic stress that protects against the trench walls from giving in. An experienced shoring expert could aid pick the method ideal suited for the situation. The shoring expert has lots of options readily available from the supplier and also the size as well as deepness of the excavation that will determine the best alternative to choose. Trench box manufacturer – authorized distributors provide tools for tiny as well as superficial excavations, long water pipes runs, going across energies, minimal accessibility, and extreme depths to name a few excavation difficulties.

When you have to excavate a trench you may need to make sure the walls are correctly shored up by to help boost security and ensure you will not need to re-dig your trench. There are several distinct shoring systems for trenches you could use to assist in preventing the failure of your trench walls, and matching the correct equipment to the job is essential for efficacy and security.

One of the simplest shoring systems for trenches to use is hydraulic shoring in which hydraulic pistons are set between steel plates or tough plywood sheets and pumped outwards until they apply the appropriate amount of pressure. You may also locate hydraulic trench boxes which are typically steel boxes with hydraulic pistons. The hydraulic shoring system will often be leased instead of purchased and is typically used for temporary trench shoring.

Various Shoring Systems for Trenches

You can even use plate and beam trench shoring systems in which I-beams are driven into the ground to support the metal plates. This procedure is typically used for bigger excavations or over longer periods of time when hydraulics are not practical option. For example, if you must use the open space in the trench to transfer staff and equipment then you not likely want flat hydraulic presses crossing the top and bottom of the trench when a placed beam can keep the walls protected. This procedure can also be used with walls which might be too far apart to reach for trenches.

Other systems, along with these two shoring systems for trenches, will have their purposes, and the type of process you use to prop up your trenches will be determined with the method you use to shore your trenches. Since not every job has the identical conditions or is of the same size, you may need to assess each trench of shoring system you will need to use. Make sure the system you use can manage pressures and the weights applied to it, be installed and removed, and can be readily obtained.

You may not need to buy a system and go to install it, only to discover it is too little or too large for the job at hand. You can find systems to lease and to buy, both online and in your neighbourhood region, and many times these same firms will can offer some guidance and training to you so you could better select, install, and use your shoring systems for trenches – accurately and safely.

In order to run pipes or electrical lines underground, trenches have to do be dug in the ground. These trenches can be quite deep and unstable without support on each side. According to OSHA statistics, the rate of fatalities in excavation work is over 100% more than other types of construction. For optimal safety, trench shoring methods incorporating trench shields are needed during trench shoring jobs. They are also called trench boxes.

In the old days, trenches were dug by hand and wood planks were used to brace the sides. These primitive guards often cracked from the weight of the mounded dirt and buried the workers in the trench alive. Unfortunately, most of them suffocated or were crushed by the rock and dirt before they could be rescued.

Trench Shoring Methods | Hydraulic Shoring

Today, trench boxes are made of heavy steel and support both sides of the trench while the construction workers are digging. The weight of the loose dirt is significant and could cause injury or death of it collapses on the workers. Some excavation companies use hydraulic trench boxes. These devices combine strong hydraulic bars against metal plates to prevent trench collapse. However, some localities are more relaxed with safety, let me put it this way, the Tampa injury attorneys are not out of work anytime soon.

Many construction workers depend on trench shoring for digging footers for large buildings and other structures. Those who build bridges have to pour cement in trenches underwater. Water and cement are extremely heavy and volatile. This extra pressure against the walls of the trenches can quickly cause a collapse without the proper equipment. Workers are much safer in the confines of a strong trench shield

It is also important to know how to space the trench shields. The project engineer must figure out how deep the trench is going to be and the amount of pressure that will be applied from each side. Trench shields come in different sizes and can be adjusted to the proper width. It is also important that the safety engineer checks each shield to ensure that it is not damaged and is in good working order before being used.

Construction and connecting resources can be a risky job. Workers’ lives are at stake when they are working in trench shoring. Having plenty of reliable trench shields reduce the chances of someone getting hurt. Prevention is the main component of safety.

The Dangers of Trench Shoring and Excavation

Trench Shoring and Excavation | Trench Shoring Boxes | Trench Boxes for Sale | OSHA Approved Trench Box
Trench Shoring and Excavation to Avoid a Cave-in.

Cave-ins pose the greatest risk and are much more likely than other excavation-related accidents to result in worker fatalities regarding trench shoring and excavation. Other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment. One cubic yard of soil can weigh as much as a car. An unprotected trench is an early grave. Do not enter an unprotected trench.

Trench Shoring and Excavation Safety Measures

Trenches 5 feet (1.5 meters) deep or greater require a trench shoring system unless the excavation is made entirely in stable rock. If less than 5 feet deep, a competent person may determine that a shoring system is not required. Trenches 20 feet (6.1 meters) deep or greater require that the protective system be designed by a registered professional engineer or be based on tabulated data prepared and/or approved by a registered professional engineer in accordance with 1926.652(b) and (c).

Competent Person

OSHA standards require that employers inspect trenches daily and as conditions change by a competent person before worker entry to ensure elimination of excavation hazards. A competent person is an individual who is capable of identifying existing and predictable hazards or working conditions that are hazardous, unsanitary, or dangerous to workers, soil types and protective systems required, and who is authorized to take prompt corrective measures to eliminate these hazards and conditions.

Entering and Exiting a Trench

OSHA standards require safe access and exit to all excavations, including ladders, steps, ramps, or other safe means of exit for employees working in trench shoring excavations 4 feet (1.22 meters) or deeper. These devices must be located within 25 feet (7.6 meters) of all workers.

General Trenching and Excavation Rules

  • Keep heavy equipment away from trench edges.
  • Identify other sources that might affect trench stability.
  • Keep excavated soil (spoils) and other materials at least 2 feet (0.6 meters) from trench edges.
  • Know where underground utilities are located before digging.
  • Test for atmospheric hazards such as low oxygen, hazardous fumes and toxic gases when > 4 feet deep.
  • Inspect trenches at the start of each shift.
  • Inspect trenches following a rainstorm or other water intrusion.
  • Do not work under suspended or raised loads and materials.
  • Inspect trenches after any occurrence that could have changed conditions in the trench.
  • Ensure that personnel wear high visibility or other suitable clothing when exposed to vehicular traffic.

What is Considered Good Trench Shoring Practice

Trench Shoring | Trench Shoring for Sale |Trench Shoring Boxes | Trench Shoring Equipment
Aluminum Trench Shoring

Construction workers charged with trench shoring and must also run close to large, rapid moving machines within constrictive as well as potentially unpredictable ground are at high risk of injury. At the same time they need to contend with the ever present dangers of water entering, uncharted underground solutions, possibly dangerous environments and also falling debris from above. Each excavation provides a one-of-a-kind combination of hazards that require the job to be very carefully coordinated, with ideal trench shields in position to safely handle the procedure. Most excavations are out in urban locations close to the general public. This needs constant watchfulness and also preparation in order to safeguard workers as well as the public.

It is recommended that for any type of high danger trench shoring a recognized expert designer is involved early in the preparation process. There is constantly an option not to offer any sort of shoring and also instead to remove dirt over a prolonged location providing a graded slope, usually at 1 in 1 forever ground problems, at little threat of collapse. This is referred to as a battered or benched excavation slope. Nevertheless, most excavations developed in urban areas do not afford sufficient room around the boundary to securely do so as well as the positioning of plant as well as access/egress for employees can provide extra threats. This element and also the expense of enhanced areas of reinstatement would generally make this option wasteful.

Undesirable Practice– Working in a deep, entirely unsupported excavation, the worker is highly at risk to any sort of abrupt ground collapse or materials/equipment coming from above the excavation.

Trench Shoring and Excavation

Analyzing the need for shoring – Work in an unsupported or inadequately assisted excavation could be particularly unsafe as the short-term stability of revealed faces is difficult to judge – even for specialists. The consequences of unexpected ground collapse or collapse when a building worker is not secured by an ideal trench shoring system are commonly severe or fatal. Collapse injuries are generally triggered by impact, squashing or asphyxiation.

Collapses are typically attributed on site to:

* Inconsistency, as well as consequently unforeseen instability, of the material being dug deep into, especially in previously disturbed ground;

* Surcharging and/or resonance around the edge of the excavation such as the operation of heavy plant or the stockpiling of dug deep into products near;

* Weather problems and/or groundwater streams negatively impacting soil residential properties;

* Poorly performed or unsuitable temporary assistance remedies

The substantial majority of excavations created in the country are relatively shallow as well as in urban areas, where the ground has actually most likely been re-worked numerous times. Made ground is particularly variable in terms of composition and behavior, as well as displays big variants in strength and also security. Analyzing the short-term stability of a dug deep into face on website by unqualified individuals is as a result very harmful and also must not be allowed. It requires a company to execute a threat assessment, determining all substantial threats and even laying out the trench system that will certainly remain till the job begins. Examining the danger and even acting upon the findings to make sure the trench job is safe and successful. A breakdown in any phase of this process could bring about catastrophe.
