Abstract
Apparatus and associated methodology contemplating an excavation shoring apparatus, having a pipe sized to circumferentially enclose at least one human user working in a subterranean excavation. A plurality of channel brackets is attached to the pipe, each channel bracket forming an elongated cross-sectional profile defining a channel having a longitudinal axis extending along the channel bracket. The excavation shoring apparatus also has a plurality of selectively removable legs, each leg forming an elongated cross-sectional profile defining a beam. Each channel is configured to receivingly engage the beam in a closely-mating slidable relationship. The excavation shoring apparatus also has a plurality of removable fasteners, each connecting one of the legs to the respective channel bracket by simultaneously passing through an opening in the channel bracket and a selected opening of a plurality of openings in the leg. The selected opening in the leg corresponds to a desired position of the leg along the longitudinal axis.
