Excavation support systems commonly used are as follows: • TRENCH SHIELD. A rigid prefabricated steel unit used in lieu of shoring, which extends from the bottom of the excavation to within a few feet of the top of the cut. Pipes are laid within the shield which is pulled ahead as trenching proceeds.
