What Are The Trench Boxes And How To Use Them Safely

Digging trenches is an important part of many constructions. The trenches are utilized to install telephone lines, pipes and any other tubular structure that must be installed deep in the earth, such as oil drills. Due to the substantial water content of these soils, trench is often a tedious job. This is because it’s hard to remove dirt and other debris from nearby objects, but also to guarantee that you are safe from serious injuries should you accidentally expose your skin.

Trenches are needed for any construction or repair work that requires access to the ground. They’re also used as protection against collapse, depending on the soil’s condition and the material the thickness of the soil. Trench boxes made of steel or aluminum framing to secure it temporarily before construction begins around them . Then, they are able to be completed using grout to attach between two layers so that no cracks can form once they’ve been properly placed at site and could cause expansion as time passes due.

Pre Installation

Before digging can begin, it is essential to determine the risk associated with the project. This includes knowledge of what equipment will be necessary and how many individuals will need access to it, and thinking about whether there may exist other ways in which the task could be accomplished without risking the life of limb (such low-invasive methods). Surveys prior to excavation must contain an assessment of risk to ensure that all potential dangers are readily identified. This helps to reduce any unexpected problems later on.

Also, you should take into consideration the depth of the trench. A 5-foot slab of concrete will support you. If the trench is more than this, then shoring or sloping will be required. However, if the 20-foot deep trench has no straight sides any building above ground must consider the greater chance of foundation movement.

The trench’s access must be made by ladders or steps. It must be the safety of access within 25 feet of workers always in the event that the need for emergency assistance arises. In addition, you might be necessary to test for toxic or low oxygen levels gasses with the use of specially designed containers known as “trench boxes.” These devices can be simple to put in place, however, you must be cautious not to place them on top of other.

Care of the trench

1. It is recommended to inspect your trench box and the supporting structure daily for signs of damage or movements.

2. Wearing protective equipment is a must on all employees working on-site.

3. You should keep all heavy equipment and tools at least three feet away from the trench edge.


Because the earth around a trench box moves, it is more difficult to install than it is to get it removed. Chain slings may be utilized to remove it or three ways to help you with one being by using an overhead crane.

1. Straight Pull Straight Pull the most basic methods for extracting materials. Attach your sling between the two points and then pull it out. There is no need for excess force or unneeded movements.

2. Half Pull Half Pull one side of the trench box and then raise as high as you are able before moving forward. You can clean dirt and other debris from the trench box and not cause any harm.

3. Single Pull Single Pull: Connect a single chain sling leg to the lifting or extraction point to shift the trench box. Then raise each of the panels by pulling one. You can remove it with your preferred pull.
