Define these words benching and battering controls in excavation work and the difference between those two words?

Benching in excavation work refers to the practice of creating horizontal steps or levels in the walls of an excavation to prevent collapses and provide a safe working environment for workers. Battering controls, on the other hand, involve sloping the walls of an excavation at an angle to prevent collapses and ensure stability.

The main difference between benching and battering controls is the method used to stabilize the walls of an excavation. Benching involves creating horizontal steps, while battering controls involve sloping the walls at an angle. Both methods are used to prevent collapses and ensure the safety of workers in excavation work.

Benching is a method of excavation where the sides of the excavation are cut into a series of steps, or benches. This helps to reduce the risk of collapse by providing a more stable surface.

Battering is a method of excavation where the sides of the excavation are sloped at an angle. This helps to reduce the risk of collapse by distributing the weight of the soil over a larger area.

The main difference between benching and battering is the shape of the sides of the excavation. Benching creates a series of steps, while battering creates a slope. Benching is typically used in excavations that are deeper than 4 feet, while battering is typically used in excavations that are less than 4 feet deep.
