Which method of trench preparation involves removing more material than shoring?

The method of trench preparation that involves removing more material than shoring is sloping. Sloping entails the excavation of the trench at an angle, allowing for a natural or designed incline of the trench walls. This method is crucial for ensuring the stability of the trench and preventing collapses. By sloping the walls, more earth is removed compared to simply shoring, which involves supporting the trench walls with structures like planks or beams to prevent them from caving in. This process is typically employed in shallow trenches, where safety risks need to be minimized while maintaining structural integrity.

In contrast, shoring focuses on providing support to the trench walls without requiring significant additional excavation. Bracing also serves to support the walls but is often used in conjunction with shoring. Reinforcement may pertain to adding strength or stability to materials but does not characterize the method of excavation itself. Understanding these distinctions is crucial for ensuring safe practices in trench work.
