The present invention relates to a support (20) for a prop (22). The prop (22) comprises a telescopic tube (26) and opposing transversely extending feet. The support (20) comprises a board (30) for contacting a support surface to transmit a supporting load thereto; a load bearing surface for receiving the supporting load from a prop (22); a bracket (32) coupled to the board (30), the bracket (32) arranged to support an end of the prop (22) at a load bearing position on the load bearing surface; and a guide for guiding the prop (22) to the load bearing position.

A flexible in-ground shield includes a first wall, a second wall, a third wall, a plurality of shoring members, and a plurality of pivoting couplers. The first wall is disposed on a first side of the flexible in-ground shield, the second wall is disposed on a second side of the flexible in-ground shield, and the third wall is disposed on a third side of the flexible in-ground shield and coupled to the first and second walls. The plurality of shoring members extend between the first wall and the second wall, and the plurality of pivoting couplers, coupled to ends of the plurality of shoring members, respectively, allow the first wall and the second wall to pivot relative to the third wall.

A system for shoring a trench, which is dug for receiving a pipeline and includes spaced apart sidewalls, includes at least two supporting units that are spaced apart from one another in the longitudinal direction of the trench and configured for absorbing transverse forces from the sidewalls. Disposed between the two supporting units is a plurality of shoring units, each configured for supporting the sidewalls of the trench. Together with the supporting units, the shoring units are configured to form a barrier-free lowering space within which the pipe can be lowered into the trench from outside the trench to the floor of the trench. A method for laying a pipe using the shoring system is also disclosed.

A wheel assembly for supporting a shoring shield is described, which beneficially does not require the use of an axle. The assembly may comprise a main support brace and an axle support brace, operably coupled by an upper transverse arm and a lower transverse arm pivotably connected to both support braces forming a parallel or quasi-parallel linkage. A rocker arm, coupled to a spring, may also be provided.

A trench-shoring sheeting panel includes a rectangular-shaped polyethylene sheet having opposing primary surfaces and four corners, a planar support structure embedded in the polyethylene sheet, a plurality of hand hold apertures formed in the polyethylene sheet, a plurality of corner holes positioned adjacent to the four corners, and a plurality of protrusions positioned on at least one of the primary surfaces.

A system for a telescopic strut includes a plurality of telescopic struts each comprising at least two hollow structural sections. Each of the plurality of telescopic struts is configured to separate a first shield wall from a second shield wall that is opposite the first shield wall. A first hollow structural section of a first telescopic strut of the plurality of telescopic struts is coupled to an overlapping second hollow structural section of the first telescopic strut by an internal retention device. The first hollow structural section and the second hollow structural section are configured to retract and extend from one another along a length of a portion of the internal retention device. The internal retention device is configured to prevent the first hollow structural section from separating from the second hollow structural section when a length of the first telescopic strut is being adjusted.

A trench box assembly including a trench box and an end cap assembly extending outwardly beyond an end of the trench box. The trench box has two metal plates and spreader bars extending between the plates. The end cap assembly includes a housing and an attachment mechanism. The housing has a first side wall, a second side wall, a top wall, and a back wall which bound and define an interior chamber of a size suitable to receive at least part of a worker's body therein. The attachment mechanism includes attachment hooks which adjustably engage the housing to the spreader bars. When the trench box assembly is installed within a trench the end cap assembly protects a worker performing a task proximate one end of the trench box from being injured by debris falling into a region of the trench adjacent the end of the trench box.
