ABSTRACT:
A trench shore consisting of longitudinal panels which cover the walls of the trench and are supported by movable frames, the panels being moved forward by jacks connecting the panels to the frames which are held in place by the friction between the walls and other panels, the shore comprising a central chamber where permanent structure is installed, with a front section with sides sloping to conform to the natural slope of the ground, and a rear section with similar sloping sides to allow for tamping and consolidating backfill material around the structure installed and with bracing arranged to allow the shore to pass completed sections of manholes; the shore being also suitable for laying pipe or tunnels under water.
