What Are The Trench Boxes And How To Use Them Safely

Digging trenches is an important component of various constructions. They are used for laying telephone lines, pipes, or any other type of tubular structure that must be placed deep beneath the ground, such as oil rigs and other. Sometimes, trenching can become a demanding because the soil found in these areas contains excessive levels of moisture. This creates difficulties when trying not only to remove any dirt that is accumulated around objects but also to keep your safety during the procedure since accidentally exposing skin can cause serious injury.

Trench boxes are essential for any type or repair that requires accessing the ground. They are able to stop the collapse of a structure based on the type of soil and the quality. Trench boxes are made using steel/aluminum frame to temporarily secure them before excavation starts. The grout is affixed between two layers, in case it is necessary, to ensure that it is not cracked when installed at the level of the site.

Pre Installation

Before digging is initiated It is important to evaluate the potential risks involved. This means knowing what equipment is required and how many people are able to access it. It also allows you to think about alternative methods of accomplishing the task without placing your life at risk. Surveys prior to excavation must contain an extensive risk assessment to ensure that any potential dangers are readily identified. This can help to avoid potential complications later on.

Also, you should take into consideration the depth of the trench. You will need assistance from sloping or shoring in the case of a 5 feet wide strips. However, if your trench is deeper than 20 feet, it will require additional engineering. This is due to the lack of straight sides at both ends. Any structure that rises above the ground has to be thought of in terms of the potential for foundation movement.

Access to the trench has to be made by steps or ladders. It is essential to keep the trench within 25 feet of the workers during an emergency. The trench box may also be used to check for low oxygen levels, toxic gases and other problems. These devices can be simple to put in place, however, you have to be careful not to place them on top of each others.

Care care for the trench

1. If you notice any indication of damage or movement, be sure you inspect the trench box on a regular basis.

2. Everyone working on site should wear their protective gear and be wearing steel-toed boots.

3. The best practice is to keep the heavy equipment and other tools at least three feet from the trench edge.


In the event of a trench, it is more likely to be difficult than digging it out because the earth around it moves. For the purpose of extraction, you may make use of chain slings. A crane that is overhead is another option.

1. Straight Pull: This is the most basic of extraction methods. Simply connect your sling to two points and then lift it away, not fumbling using excessive force or unneeded movements.

2. Half Pull: A half pull is used to attach the trench box on one side and lift as much as possible. It is possible to remove dirt and debris out of the trench without causing any damage.

3. Single Pull: You link one end of chain to your lifting point or extraction location. Each panel is raised at a different time. Pull the lever to take away the trench box.
