What You Need To Know About Trench Boxes

Digging trenches is an important component of several constructions. They are used to lay telephone lines, pipes or any other tubular structure that has to be installed deep underground like oil rigs, oil pipelines, etc. Because of the heavy moisture content in these soils, trench can be an arduous task. It is due to the fact that it is difficult to remove debris and dirt from surrounding objects but also ensure safety as you could inflict serious injuries should you accidentally expose your skin.

Trench boxes are required for any type of repair or construction work which requires access to the ground. They’re also used as protection against collapse, based on the soil’s condition and the material thicknesses used to construct them. Trench boxes being made out of steel framing or aluminum to temporarily secure it prior to construction, and excavation within them, and then finalizing the installation by fixing grout between two layers, if required to ensure that no cracks form when properly installed at site the level, which can lead to expansion in time due to.

Pre Installation

Before digging begins before digging, it is crucial to assess the risks involved. This includes knowing the equipment that is needed and the number of individuals have access. It also allows you to think about other ways of completing the task without risking your life. Additionally, a thorough risk assessment should be done prior to the excavation survey in order to ensure that all hazards can be easily identified prior to the excavation. This can help prevent any problems in the future.

Also, you should take into consideration the depth of the trench. You will need support via sloping or shoring, if you have a an area of 5 feet in width. But, if the trench is deeper than 20 feet, it will require extra engineering work. This is because of the lack of straight sides at either end. Any building that rises above the ground should be considered in light of the potential for foundation displacement.

Access to the trench has to be gained via ladders or steps. Safe access must always be within 25 feet of the workers during an emergency. The trench box can also be used to test for low oxygen levels, toxic gases and other problems. The installation of these articulated devices is simple, however they increase the chance of stacking them over one another since you do not know the height at which your piles will reach into their vulnerable bottom.

Care care for the trench

1. In the event of any movement or damage, make sure you inspect the trench box each day.

2. Every person working on the site should wear their protective gear and wear steel-toed shoes.

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


A trench box installation is more likely to be difficult than excavating it since the earth around it moves. To extract it, you could make use of chain slings. An overhead crane is also an option.

1. Straight Pull: This method is the most straightforward. Attach your sling to the two points, then pull it out. There is no need for excess force or unneeded movement.

2. Half Pull: Attach the half-pull to one end of the trench box and then raise as high as you are able before moving onto the next. You can clean dirt and debris from the trench box without causing any harm.

3. Single Pull: To move the trench box you connect a single piece of chain sling to an extractor or lifting point and raise each panel in turn. Make use of your pull to lift the trench box.
