Understanding The Trench Box System

Digging trenches is a crucial element of various constructions. They are utilized for the construction of pipes, telephone lines, or any other tubular structure which needs to be installed deep underground like oil rigs, for instance. Due to the substantial water content of these soils, trench can be a laborious task. This is due to the fact that it is difficult to remove dirt and debris from surrounding objects but also ensure security as you may cause serious injuries if you accidently expose your skin.

Trench boxes are needed for any type or repair that involves accessing the ground. They are able to prevent collapse depending on the material and soil quality. Trench boxes are made from aluminum/steel frame to temporarily secure them before excavation starts. The grout is placed between two layers if necessary, so it is not cracked when placed at the site level.

Pre Installation

Before digging gets underway It is vital to determine the risk to be taken. It is vital to know the type of equipment used and how many persons require access. Also, think about alternatives which could have been utilized to finish the job without risking life or limb risk (such as the use of minimally-invasive methods). A complete risk assessment must also take place during pre-excavation assessments to ensure that all potential dangers can be easily recognized prior to time; this can help reduce unforeseen complications later downline.

You should also be aware of the depth of your trench. It will require assistance from sloping or shoring, if you have a 5 feet wide strips. If the trench is more than 20 feet in depth, it will require extra engineering. This is due to the lack of straight sides at the ends. Anyone who builds above the ground should be considered in light of the potential for foundation displacement.

Access to the trench has to be done via ladders or steps. There should be safe access within 25 feet of workers whenever the need for emergency assistance arises. In addition, you could be necessary to test for toxic or low oxygen levels gasses using specially designed boxes called “trench boxes.” These articulated devices make the installation easy, however they can increase danger when stacked over one another because you are not able to predict how high your pile will break through into their vulnerable underbelly.

Care: Caring for the trench

1. It is recommended to inspect your trench box and the supporting structure every day for damage or movement.

2. All personnel working on site should wear their personal protective equipment and wear steel-toed shoes.

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


Since the ground around a trench box moves and it’s more difficult to build than to take it out. Chain slings can be used to extract it or three ways to help , one of them being using an overhead crane.

1. Straight Pull: This technique is the easiest. It’s as easy as attaching your sling to two points before lifting it out.

2. Half Pull Half Pull: Attach the half pull to one side of the trench box and then lift it as far as you are able before moving on. This will allow you to clear all dirt and debris inside the trench without causing damage to your garden.

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 at a time. It is possible to remove it using your trusty pull.
