How Are Trench Boxes Used?

The excavation of trenches is an essential component of a variety of constructions as well as engineering sites. They are utilized for the construction of pipes, telephone lines, or any other type of tubular structure which needs to be put in deep underground, like oil rigs, etc. Trenching in these areas is often difficult due to the excessive amount of moisture. It’s not easy to remove all dirt from objects, but it is equally dangerous to expose the your skin to the dangers of.

Trench boxes are necessary for any type or repair which requires access to the ground. They are able to avoid collapse based on the type of soil and the quality. Trench boxes are constructed from aluminum/steel frame to temporarily secure them before excavation begins. The grout is affixed between two layers, should it be necessary, ensuring that no cracks develop when properly installed at the level of the site.

Pre Installation

Before you start digging before you begin digging, it is essential to know the possible dangers. This involves knowing the type of equipment needed and how many persons will need access to the area, as well as thinking about the possibility of other means by which the job could have been completed without risking life or the limb (such minimally invasive techniques). Pre-excavation surveys must include the full risk assessment needed to ensure that any potential dangers are readily recognized. This can help to avoid any unexpected problems later on.

It’s also crucial to consider the depth of your trench. You will need support via sloping or shoring in the case of a a 5-foot-wide strip. But, 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 either end. Any structure that rises above ground must consider the potential for foundation moving.

A ladder, steps or ramp should be used to gain access to the trench. There must always have been an accessible area of 25 feet of the workers at all times in case an emergency occurs. You could be necessary to test for low oxygen levels or toxic gasses through specially-designed boxes referred to as “trench boxes.” These articulated devices are very simple to set up, however you have to be careful not to pile them on top of each other.

Care The trench: Caring for it

1. Check the trench box and support every day for signs of damage and any movements.

2. Always ensure that protective gear is used by every employee working on-site.

3. It is essential to ensure that heavy equipment and tools are kept at least three feet from the trench’s edge.


Since the ground around a trench box moves, it is more difficult to set up than to get it removed. To extract it, you could use chain slings. A crane that is overhead is also an option.

1. Straight Pull: This is the most straightforward. Attach your sling between the two points and pull it out. It is not necessary to exert any force or unneeded movements.

2. Half Pull: Attach the half-pull to one side of the trench box, and then lift as much as you are able before moving onto the next. You can remove dirt and debris out of the trench box without causing any damage.

3. Single Pull A single chain sling leg with the lifting point to move the trench box. Then, raise each panel individually by pulling one. When the time comes for removal however, you can use your trusted pull.
