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.
Excavation is also a utilitarian function. Have you ever had a pool installed in your back yard? The hole the contractors dug is an example of excavation at work. The same thing may be said for cellars, dams, and other structures which necessitate partial burial in the Earth. Furthermore, excavation is a medical term. In this capacity, it involves the removal of fat or other types of unwanted or unneeded tissue, including tumors and the like. In asking What is excavation?, it is perhaps helpful to add a bit of historical perspective.
