Sheeting means the members of a shoring system that retain the earth in. position and in turn are supported by other members of the shoring system. See. figure 2.0. Shield (Shield system) means a structure used in an excavation to withstand. cave-ins and which will protect employees working within the shield system.
Shields and speed shores are the next choices if an open cut is not feasible, but the soil must stand nearly vertically long enough to excavate and backfill. The most expensive trench support methods are shoring methods such as soldier piles, sheet pile, or modular shoring.
