Understanding The Trench Box System

Numerous engineering sites and construction projects require trench digging. These trenches can be constructed to lay telephone lines, pipes and any other tubular structure that needs to be set deep beneath the ground, like oil drilling rigs. Because of the high moisture content of the soil, trenching is a difficult task. This is due to the fact that it’s difficult to not just remove debris and dirt from surrounding objects but also to ensure the safety of your family members as you can cause severe injuries if you expose your skin.

Trench boxes are required for any type or repair that involves accessing the ground. They’re also used as protection against collapse, contingent on soil quality and material thicknesses put in place with Trench boxes constructed of steel and aluminum framing in order to temporarily secure it prior to installation while excavation takes place around them then finalizing by affixing grout between two layers if needed to ensure that no cracks form when installed properly at site level which could lead expands over time because of.

Pre Installation

Before digging is initiated, it is essential to determine the risk to be taken. It is vital to know which equipment is required and how many individuals will need access. Also, reflect on the other options that could have been employed to accomplish the task without placing lives or limbs at risk (such as techniques that are minimally invasive). A thorough risk assessment should be done prior to the excavation survey in order to ensure that any hazards are easily identified prior to the excavation. This will help avoid any complications later.

It’s equally important to take into consideration the depth of your trench. If you’re working on a 5-foot wide strip and you need support, either sloping or shoring will be needed based on how wide the trench gets. However, if the trench is 20 feet deep, it will require additional engineering design, because there are no straight sides at either end, this implies that any structure above ground must take into account the increased risk of foundation movement that is directly to the excavation site.

The access to the trench should be gained via ladders or steps. In the event of an emergency, there must be an accessible area of 25 feet or less. It is also possible to test low oxygen levels as well as toxic gases in specially-designed boxes referred to as “trench box”. These devices can be simple to install, but you have to be careful not to stack them on top of each others.

Care: Looking after the trench

1. In the event of any movement or damage, make sure you look over the trench box every day.

2. If working on site, all personnel should be wearing their protective equipment and wear a steel-toed boot as well as high-visibility clothing.

3. Heavy equipment and tools should be kept at least 3 feet away from the edge of any trench.


It’s more challenging to construct a trench than to clean it up, since the earth around it moves. For removal, you can employ chain slings. A crane that is overhead can also be used.

1. Straight Pull: This is the most simple. Simply attach your sling to two points and lift away, not fumbling with excessive force or inefficient movement.

2. Half Pull Attach the half-pull at one side of the trench box, and then lift as much as you are able before moving onto the next. This will permit you to remove any dirt or debris without causing damage to your lawn.

3. Single Pull: Attach a single chain sling leg to the lifting or extraction point to lift the trench box. Then you can raise each panel using a single pull. Pull the lever to take away the trench box.
