ABSTRACT:
An apparatus for shoring an excavation site includes a plurality of interlocking panels. Each panel includes inner and outer plates spaced apart from one another by beam supports. The panels have a bottom cutting edge for anchoring in the soil forming the bottom of the excavation site. Ball or socket joints are disposed, one each, along opposed vertical edges of each panel so that adjacent panels can be interlocked. A plurality of wales are provided for additional support. A method for shoring an excavation site includes the steps of interlocking a set of panels to enclose a space corresponding to the excavation site and installing the interlocked panels in the site. Sets of wales are then installed adjacent the inner plates of the panels for additional support.
