Question: 1 / 425

What is the primary purpose of sloping cuts trench walls?

To enhance aesthetic value

To overcome collapsing pressure

Sloping cuts in trench walls serve the primary purpose of overcoming collapsing pressure. When a trench is excavated, the walls can become unstable, and the risk of soil collapse increases, particularly in loose or wet soils. By sloping the walls at a specific angle, the stability of the trench is significantly improved. This angle allows the weight of the soil above the trench to be distributed more evenly and reduces the likelihood of a collapse, thus ensuring a safer working environment for personnel.

While other factors may play a role in trench construction, such as preventing water accumulation, facilitating access, or even aesthetic considerations, the foremost concern in excavation safety is to maintain structural integrity and worker safety by managing earth pressures effectively. Therefore, sloping walls is a critical practice in trenching operations to mitigate the risks associated with soil collapse.
