Quality Inspection for Subway - Trench Box – Lianggong

Product Details

Trench boxes are used in trench shoring as a form of trench ground support. They offer an affordable lightweight trench lining system. They are most commonly used for ground works operations such as installing utility pipes where ground movement is not critical.

The size of the system required to use for your trench ground support depends on the your maximum trench depth requirements & the size of the pipe sections that you are installing in the ground.  

The system is used already assembled in the job site. The trench shoring is made up of a basement panel and top panel, connected with adjustable spacers.

If excavation is deeper, it’s possible to install elevation elements.

We can customize different specifications of trench box according to your project requirements 

Common Uses for Trench Boxes

Trench boxes are used primarily in excavation when other solutions, such as piling, wouldn’t be appropriate. Since trenches tend to be long and relatively narrow, trench boxes have been designed with this in mind and are therefore much better suited for supporting unsloped trench runs than any other type of excavation structure. Slope requirements vary by soil type: for example, stable soil can be sloped back to an angle of 53 degrees before requiring additional support, whereas very unstable soil can only be sloped back to 34 degrees before a box is required.

Benefits of Trench Boxes

Although sloping is often seen as the least expensive option for trenching, trench boxes do away with much of the associated cost of soil removal. Additionally, boxing a trench provides a huge amount of additional support which is vital for the safety of trench workers. However, proper use is essential for ensuring your boxes are providing optimal protection, so make sure to research your trench specifications and requirements before proceeding with box installation.
