Modular trench box sheeting

摘要

Modular trench box sheeting panels for use in wall supporting during the excavation of trenches or the like. A rectangular support frame is formed by a pair of sheeting support members secured to one another by pairs of spreader members at oppositely disposed ends thereof. The box sheeting panels of the invention are formed of modular interdependent structural shapes that are assembled in a modular fabrication method to form interengageable adjustable wall sheeting panel members with reinforced pounding plates and ground engaging knife edges.
