How Are Trench Boxes Used?

Digging trenches are an essential part of various constructions. They are utilized to install telephone lines, pipes as well as any other tubular structure that needs to be set deep underground, such as oil rigs. Trenching can be a strenuous work as the soil found in these areas is characterized by high levels of moisture which can make it challenging not only to eliminate any dirt that is accumulated around objects but also keep your safety during the procedure as accidentally exposing your the skin can result in severe injuries.

Trench boxes are crucial for any kind of construction, or repair that must be performed in the ground. They can be used to avoid collapse based on the material and soil quality. Trench boxes are constructed of steel and aluminum frames to temporarily secure them prior to excavation starts. The grout is then secured between two layers when necessary, to ensure that there are there is no chance of cracks forming when set up at the ground level.

Pre Installation

Before you dig prior to digging, it’s important to know the possible dangers. This includes knowing what equipment is required and how many people need access to it, and an evaluation of the possibility of other ways in which the work could have been done without risking life and the limb (such minimally invasive techniques). Before excavation surveys should include an extensive risk assessment to ensure that any potential hazards can be easily discovered. This will help reduce any unexpected problems later on.

You should also take into consideration the depth of the trench. A 5-foot slab of concrete will be able to hold you. If the trench is larger than this, then shoring or sloping may be needed. But, if the 20-foot deep trench has no straight sides the building above it must account for the increased chance of foundation movement.

The trench’s access must be made by steps or ladders. It must be an accessible area of 25 feet of the workers throughout the day in case the need for emergency assistance arises. In addition, you may also need to test for low oxygen levels or toxic gases through specially designed containers known as “trench boxes.” These articulated devices are easy; however they increase the risk of stacking them over one another because you are not able to predict how high up your piling will penetrate their vulnerable underbelly.

2. On-site the personnel must be wearing protective gear and be wearing a steel-toed shoe as well as high-visibility clothing.

3. It is recommended to keep all heavy equipment and tools at least three feet from the trench edge.


Installing a trench box will be more difficult than digging it out because the earth surrounding it moves. Chain slings may be utilized to extract the soil, as well as three different methods for lifting it. The third option is to use an overhead crane.

1. Straight Pull Straight Pull basic of all extraction methods. Simply attach your sling two points, then pull it out, no fussing around using excessive force or unneeded movements.

2. Half Pull: A half-pull can be used to secure the trench box on one side , and to lift as much as you can. This will help remove all debris and dirt inside without causing too much damage to your lawn.

3. Single Pull: To relocate the trench box, you connect a single piece of chain slings to an extraction or lifting point and raise each panel at a time. When the time comes for removal however, you can use your trusted pull.
