What does "benching" refer to in excavation work?

Benching in excavation work refers specifically to the process of shaping the trench walls to prevent collapse. It involves creating a series of horizontal steps or "benches" in the trench walls, which helps to enhance stability and safety during digging operations. By providing these stepped levels, the risk of the walls caving in is significantly reduced, ensuring that workers can operate more safely in the trench.

This technique is crucial, especially in deeper excavations, as it allows for better load distribution on the soil that remains intact, thereby protecting both the workers and the integrity of the surrounding environment. Proper benching techniques are essential for complying with safety regulations and ensuring that excavation sites are properly managed.
