Abstract
A trench shoring apparatus braces the substantially vertical walls of an earthen excavation. Telescoping wall support legs permit the apparatus to be easily adjusted for use in trenches of various depths. Horizontal wall support arms joined to the wall support legs retain and stabilize trench wall soils and provide a mechanism for mounting additional soil retaining components. Flexible anchor support arms transfer the load produced by the shifting trench walls to a location remote from the trench. The trench shoring apparatus, additionally, may be partially folded and disassembled for ease in transportation and storage.
