ABSTRACT:
An excavation shoring system having four vertical, cylindrical poles, each connected to a base element, arranged to constitute corners of a rectangle. At least one vertically oriented shoring panel corresponding to each side of the rectangle is provided, with each of the shoring panels corresponding to adjacent sides of the rectangle having one end rotatably connected to a first pair of diagonally opposed cylindrical poles in a manner forming four vertical walls of uniform height. At least two vertically oriented, U-shaped channels disposed at right angles to each other are connected to a second pair of diagonally opposed cylindrical poles. The U-shaped channels have a channel width substantially corresponding to a thickness of the panels and are oriented to receive a free end of each shoring panel.
