Knowing what they are and how to evaluate and accommodate for them are critical to keeping workers safe.

Trenching St. Louis

Trenching is one of the most dangerous practices that you can engage in within the construction industry. Trenching is a way to build a structure to ensure the integrity of a worksite that may not be stable. There are many things that you have to take into consideration when devising the best trenching practices. One that might seem like the most benign, but it’s one of the most critical: being able to evaluate and accommodate various types of soil conditions.

Since your trench will rely on how well it holds up the surface around the worksite, things like soil type, the moisture that it retains, and the type of composition it contains should all help to determine the best way to shore things up to keep everyone safe.

There are many stresses that can be placed on the soil at a trenching site. Knowing what they are and how to evaluate and accommodate for them are critical to building the safest trenching operation possible.

Stable Rock

Stable rock soil conditions exist when there is natural mineral matter that can be extracted with both sides exposed. Examples of stable rock are sandstone and granite. Although it’s more difficult to crack, once you have a trenching site comprised of stable rock you have more stability, and it is impervious to weather conditions and cracks.

Type A Soils

Type A soils are unconfined and have a compressive strength of 1.5 tons per square foot or more. Things like clay, clay loam, sandy clay, or silty clay are examples of type A soil. It’s not impervious to water conditions, so weather and running water need to be accommodated for when trenching in type A soils.

Type B Soils

Type B soils are unconfined and have a strength of more than 0.5 but less than 1.5 per square foot. Examples of type B soils are silt loam and angular gravel. As they are more unstable than other types of soil, water and weather conditions definitely need to be factored in for safety.

Type C Soils

Type C soils are unconfined soils that have the strength of less than 0.5 per square foot or less. They are gradual in nature and pose the biggest threat of danger in a trenching site. They are the most unstable, so if you are trenching in type C soils you will need to either dig deeper, slope horizontally or vertically, and anticipate weather or water changes.

Layered Geological Strata

If you are dealing with soil that is geologically altered, then you have to take into account the various levels of soil and accommodate accordingly. Dealing with layered geological strata creates a highly complex trenching site, and there are many conditions to consider.

St. Louis Trench Shoring

Trenching is an extremely dangerous part of the construction industry and it’s heavily guided by the conditions that surround the work site. Chief among those concerns are the type of soil and how weather and other conditions will affect its integrity. If you are designing a trenching operation, it is imperative to get the help of a professional St. Louis trenching and shoring professional to ensure that you are taking soil and all other things into consideration.

If excavation work sites aren’t properly constructed, then this puts the workers at great risk.

Trench Safety St Louis

Trenching and excavating are both extremely dangerous processes involved in many construction projects. Because of the high levels of risk, the Occupational Safety and Health Administration (OSHA) heavily monitors the way that trenching and excavation sites are constructed. If worksites aren’t properly constructed, there is a high probability that you can compromise the integrity of your structure and that an employee will end up getting injured.

OSHA Safety Procedures

OSHA regulates the particulars about how a trenching or excavation site is built and maintained. The newest guideline changes cover the following parts of operation:

  • Dangers related to trenching operations. Since trenching sites are so dangerous, OSHA guidelines are in place to prevent cave-ins that can jeopardize workers, create hazardous atmospheres for surrounding environments, and limit the hazards associated with the machinery needed for trenching.
  • The classification of soil types. Trenching sites differ according to the type of soil surrounding them. Since the soil type can greatly affect the risks associated with trenching sites, there are guidelines on how the soil is classified.
  • Who is running the trenching site? There are specific things that the supervisor of a trenching site must know to keep things running smoothly and safely. OSHA requires that every trenching site have a “competent person” in charge to ensure that the trench is both constructed and maintained in a specific manner to limit risks. That person needs to have experience with site inspection, soil classification, structural ramp design, water removal monitoring, knowledge of water removal equipment and protective systems.
  • Planning factors ahead of time. Before a trenching site can be put into execution, there needs to be a lot of pre-planning done to accommodate risks and to make the site as safe as possible. Since no two sites will ever be the same, they must be approached with specific conditions in mind and constructed accordingly.
  • Working around existing utilities. Before you can begin to construct a trenching site, it must be examined to ensure that there aren’t any existing utilities hidden underground, like a gas line. Before you dig, you have to call 811 to have an inspection of the site to ensure that you aren’t going to be digging into something dangerous.
  • Protective systems necessary during excavation. Before you even start excavating your trenching site, you have to determine the bench and the slope of the operation. It is also required that you appropriately support all sides of the excavation site, and to shield the site and the work area to keep people out.

Because trenching is such a dangerous part of a construction worksite, there are many restrictions on what you can and can’t do, and how trenching sites are managed and who can manage them. It is important to know what the OSHA guidelines are to keep your workers safe and to stop yourself from incurring fines and being cited for unsafe practices.

Trench shoring is a procedure that braces the walls of a trench to prevent collapse and protects workers.

Trench Shoring St. Louis

Trenching and excavation are some of the most hazardous occupations. A number of workers get injured every year while performing their jobs. So it is imperative to have a protective system to ensure the safety of trench workers.

The competent person is responsible for deciding and implementing the protective measures. He has the ability and experience needed to identify the potential and existing dangers at the site. He is expected to choose the protective system on the basis of the type of soil and the depth and width of the trench.

The Dangers Involved in Trenching

The earthen walls of a trench can collapse and injure the workers inside. This is the most important danger faced by the employees who work on an excavation site. Besides this, the workers can get injured in other ways. If the work site is cluttered the workers can slip and fall. They can get a shock from the underground or overhead electrical lines.

They have to work in the proximity of high traffic and utilities and manually handle material and heavy machinery. All of this can be dangerous.

Different Protective Systems

  • Shoring – In this, the sides of an excavation are supported by posts, struts, wales and sheeting made of timber, and hydraulic or mechanical structures. This method is suitable for providing protection in excavations where sloping is not practical because of the depth or location of the trench. Shoring provides even pressure. The workers do not have to enter the trench to install it.
  • Shielding – Shielding involves the use of a trench box or shield. It does not avert a cave-in. Instead of this, it protects the workers from harm if there is a cave-in. This protective system is useful for a continuous installation work like laying pipes. The workers can drag the box with them wherever they work.
  • Sloping – This is a protective system in which the earthen walls of an excavation are cut back at an angle to avert a cave-in.
  • Benching – In this method, the walls of the excavation are cut into steps to prevent a cave-in and provide protection to the workers.

Advantages of Shoring and Shielding

Sloping and benching are not practical for most of the excavations. A large amount of space is needed to dig the trench at the correct angle. Often this is not possible because the excavations have to be done in busy areas where there is a lot of traffic.

Another reason why they are not very suitable is that towards the end the soil which has been removed has to be put back and compacted, this costs extra money and time.

Shoring and shielding are more advantageous. They are more economical than sloping and benching. They maintain the trench walls in a vertical position. This reduces the quantity of excavated soil and fuel consumption. It also makes the work of restoring the yards, asphalt and pavement easier.

To keep workers safe don’t set unrealistic goals or offer incentives for things to get done quickly or under budget.

Trench Safety St. Louis

Trenching is considered a highly-dangerous occupation in the construction field. The reality is that just one yard of cubic dirt can weigh as much as 3,000 pounds, which is enough to crush a worker or trap him underneath if the trench is compromised and gives in. That is why having the proper safety measures in place is so crucial to keep everyone safe on a trenching site.

Why Trench Safety is So Important

Fatal trenching incidents have as much as doubled in just the last year. OSHA, the Occupational Safety and Health Administration, insists that if better safety measures had been implemented, most of those accidents would not have happened. If trenching companies would do a better job of keeping sites safe, then the number of accidents would decrease significantly. Keeping your job site safe is not only a moral obligation, it is also a law. If an accident happens, it is possible for those in charge to face criminal charges.

Setting Realistic Time Frames

One of the biggest reasons that things go wrong is because trenching workers are often on tight schedules to get jobs done. When they are in a time crunch, it is not uncommon for them to cut safety corners to finish on time. That can lead to workers and managers being careless and making decisions based on time efficiency, rather than on the safety of employees. Make sure to set realistic goals when you are running a trenching operation. Scheduling strict time frames that are unrealistic will only jeopardize your workers and increase the likelihood of accidents.

Another reason that things go awry and workers get hurt is that supervisors and managers are often given incentives in the form of bonuses for getting a job done on time or even ahead of schedule. To cut costs, supervisors will bend the rules or put workers in riskier positions to get goals met and to reap the benefit. As a trenching company, you do want to set goals and to offer an efficient operation, but offering your supervisors and managers money to get it done quickly might not be the best way to ensure the safety of your overall operation.

Finally, it costs more to do things right. Having the proper safety measures in place is a little costlier for the company and hiring safety managers might seem like an additional cost that can hurt a company’s bottom line. But what will really put a kink in your budget would be if your operation was shut down, you are fined, or someone gets hurt and you face criminal prosecution.

Trenching is a highly dangerous but necessary component of construction. If you want to keep your workers and your operation safe, then don’t set unrealistic goals or offer incentives for things to get done quickly or under budget. Invest in your workers, and they will invest in your company. It will also ensure that the job gets done right and that everyone is much safer.

Shoring is the most economical and safest method of protecting trench workers.

Shoring St. Louis

Cave-ins are the biggest hazard faced by the trench workers. An unstable trench can collapse and kill or injure the workers at any time. So it is essential to have a suitable protective system in place.

A number of methods like shoring, shielding, sloping and benching are available to protect the workers. Among them, shoring is the most economical and efficient.

Reasons for Cave-Ins

There are a number of factors which can influence the stability of the trench. Some of them are:

  • The kind of soil and its moisture content.The kind of soil and its moisture content.
  • Unfavorable weather conditions.
  • Improper installation of the trench box or support system.
  • Vibration.
  • Depth of the excavation.
  • The duration of time for which the trench is left open.
  • Surcharge or excessive weight near the excavation.
  • Adjacent structures and buildings.
  • Previous soil disturbances or excavations.

Other Hazards Involved in Trenching

Besides cave-ins, trench workers face some other dangers also:

  • They may trip, slip or fall while entering, egressing or working in the trench.They may trip, slip or fall while entering, egressing or working in the trench.
  • The workers may not have sufficient protective equipment.
  • They may come into contact with the overhead electrical conductors or the underground utilities.
  • Working with heavy equipment near the excavation can be dangerous.
  • Traffic on the public roads and the site may pose a danger.
  • Working in hazardous atmospheres and confined spaces may prove to be harmful.
  • There are chances of being hit by falling equipment, materials or vehicles in the excavation.
  • The adjacent structures may become unstable because of the excavation and pose a problem.
  • It may be risky if the excavated material is not stored at a suitable distance from the trench. 
  • Finally, water hazards like flooding can cause accidents.

Benefits of Trench Shoring

In the olden days, sloping and benching were used to prevent the sides from collapsing while digging deep holes. In sloping the walls of the trench slope at an angle so that they do not cave-in. Benching or terracing is a method in which the sides of the trench are formed in steps in order to prevent them from collapsing.

Sloping does not require any additional equipment. It is quite a safe procedure if the degree of the slope is proper and the weather is favorable.

But in the modern days shoring and shielding are considered to be the most economical and safest methods of protecting trench workers from a cave-in. At an excavation site shields protect the workers from a cave-in. Shores support the walls of the excavation with a system of hydraulic cylinders and stop them from collapsing.

Shoring is more beneficial in some situations because of its flexibility and versatility. It is very useful for spot bracing. This method is most suitable when the work is being done near sidewalks or curbs, around existing utilities, or any place where a backhoe or mini-excavator is used.

Shores are lightweight. The workers can easily install and remove them from above the trench.

Trench shields play the most important role when it comes to safety of workers working in a trench.

trench safety st louis

Trench workers have to perform their duties in perhaps one of the most hazardous and stressful conditions. Trenches are often dug out in industries such as construction for laying the foundation of a building, for pipe laying or underground wiring jobs.

Trench shields play the most important role when it comes to safety of workers working in a trench. A good and strong trench shield helps keep the work space safe and protects workers from hazardous trench collapses. Trench shields function to keep the side walls of the trenches secure and prevent them from caving-in.

It is therefore essential that employers understand the qualities of a good trench shield, appropriate handling procedures and what type of trench shield is ideal for the job. Our St. Louis trench shoring services experts explain this in detail.

What are Trench Shields

All trenches can at some point in time collapse or cave in. It is therefore important that trench shields are chosen on the basis of the depth of the trench dug out and the quality of the ground material that the trench is made of. Trench shields are most commonly made of either steel or aluminum. Such trench shields have the ability to maintain a rigid hold on the trench walls, giving workers the ability to focus on the job at hand better and more time to complete their job before the trench walls cave in.

Sizing a Trench Shield

Sizing a trench shield is an important step. Therefore one has to be equipped with the correct information about sizing trench shields. While sizing a trench shield, one should choose a trench shield based on the size of the trench, the weight of the shield that is going to be handled by trench shoring equipment, know the depth of the trench, the quality of soil on which the trench is built, have an clear idea about the size of diameter of the outside pipe and the lift capacity of the excavator.

Trench Shield Assembly and Handling

Once a trench shield type is chosen, it is important that it is assembled exactly according to the manufacturers manuals provided. Moreover, those engaged in trench shield assembly should be well trained and have enough experience in assembly and handling of trench shields. They should use all original parts such as the rebar, bolts, pipe, spreader pins etc. and these should never be substituted. The keepers of the trench shield should always be properly installed.

Safety is always the number one priority at any workplace. Trenches are no different. It is mandatory that all aspects of safety are covered. The first and foremost safety check is to ensure all trench shield operators and supervisors receive proper training with regards to correct practices of assembling as well as handling trench shields. All workers and operators should be provided with proper personal protection equipment like helmets while working in the trenches and while operating trench shields.

When it comes to excavating projects, rely on Luby Shoring’s expertise.

st louis trench shoring

An aluminum trench shoring system is used on the sites where the ground is unstable. The
walls in a trench are braced with the trench shoring boxes so that they do not collapse. This
helps protect workers from getting injured while performing their tasks in trenches.

The trench boxes have spring mounted flexible spindles. The cut and lower method is used
to install them. The thickness of the plates vary.

Employee Safety

Top priority is given to the safety of workers on any construction site. The task of excavation can be very risky. Workers often have to work in trenches which are several feet deep and extend for miles. The most dangerous part of the job is that the walls of a trench or an excavation may cave-in and trap the workers under the dirt and other materials.

Companies use different types of equipment to avoid such accidents and to make the job
safer for the employees.

Types of Hydraulic Aluminum Trench Shoring Systems

Various types of equipment can be utilized according to the size and type of the trench. The
most popular ones are:

  • Hydraulic shoring – In this method, hydraulic pistons are used with heavy plywood or steel plates to shore up the trench. First, the plywood or the plates are put in the appropriate places. After that, the pistons are positioned. They are activated till they press against the walls. In this way the place is made safe for the workers.
  • The soldier boarding method is used for some type of trenches.
  • The beam and plate method – First, steel beams are fixed in the ground. Then steel plates are inserted between them. This helps to shore up the walls of the trench. Wooden planks are utilized instead of steel plates in some jobs.

Some people have an impression that trenches are dug to install pipes or some other things below the ground. However, trenches are dug for other purposes also. They are required for installing manholes too. It is equally important to shore up such trenches and make them safe.

An Innovative Method of Shoring

New methods have been developed to make the trenches safe for the workers. The fin form
takes advantage of the pressure exerted by the surrounding ground on the trench walls. In
this, first when the walls are put into the ground they are slightly angled. Then they bow out and become straight. In this way, they create a very tight fit and it is not possible for the trench walls to waver or collapse. The fin form walls are frequently used in manhole
construction where the spaces are narrow and tight and there are more chances of collapse. 

The hydraulic aluminum trench shoring products like vertical shores, hydraulic shields, end
shores, manhole shoring and waler systems are very useful for doing spot repairs, and for
working in tight situations, or working in places where it is not possible to use bulky
machinery.
