Shoring (Shoring System): a structure that is built or put in place to support the sides of an excavation and designed to prevent cave-ins. Sides: See Faces. Sloping (Sloping System): sloping the sides of the excavation away from the excavation to protect employees from cave-ins.
Sloping involves cutting back the trench wall at an angle inclined away from the excavation. Shoring requires installing aluminum hydraulic or other types of supports to prevent soil movement and caveins.
