Abstract
An excavation hole shoring system is disclosed which employs a plurality of shoring panels positioned between adjacent vertical soldier beams around the periphery of an excavation hole. A plurality of horizontal reinforcing members form a box frame around the hole's periphery at grade level, and each of the soldier beams is attached to an adjacent one of the reinforcing members with a metal strap. Each of the soldier beams includes a pair of longitudinal guide beams which form front and back channels for reception of front and back shoring panels. The front shoring panel is employed to shore the lower portion of an excavation hole, while the back shoring panel is employed to shore the upper portion of the hole. The two panels are therefore vertically staggered in an overlapping fashion so that holes of varying depths can be shored with the same shoring system. The shoring system is put in place progressively as the excavation proceeds, and no workers are required to enter the excavation during the installation of the system. When this work is completed, the shoring system can be quickly and easily removed during back filling of the excavation hole.
