ABSTRACT:
The invention refers to means of shoring trench excavation.
It provides a trench shoring apparatus which supports the walls of the trench and can travel by its own power or be pulled behind an excavator and consists of panels which line the walls of the trench and have braces across the trench between them, each panel comprising a frame that supports a vertical tread endless crawler track which travels longitudinally around the frame, the panel being enclosed to prevent the entry of earth, and of a construction and size suitable for being easily joined to others and cross braced to form an assembly for various depths of trenches.
The apparatus may be used for underwater pipelaying.
