A trench box has first and second side panels connected in parallel spaced relation by first and second lateral supports. Each lateral support comprises connection points at each end of each lateral support that connect the side panels to the lateral supports. The connection points maintain the side panels in parallel spaced relation and the lateral supports in parallel spaced relation between the side panels. Each connection point comprises a pivot connection that permits pivotal movement of the side panels relative to the lateral supports about a pivot axis, and a releasable connection spaced from the pivot connection in a direction perpendicular to the pivot axis. The releasable connection is selectively releasable to permit the respective first or second side panel to pivot about the pivot axis such that the panels are not parallel.

The trench shoring apparatus includes first and second side panels having a top edge, a bottom edge and side edges. The first and second side panels are connected in a parallel spaced-apart configuration by a transverse strut being mounted proximate each side edge thereof and nearer the top edge than the bottom edge. An actuator varies the length of the transverse strut from a first length to a second length.

A panel for shoring a wall of a trench, the panel including an outer face arranged to face the wall, an opposing inner face, opposing sides, a top end and a bottom end, wherein the panel includes fixed couplings located at or adjacent to the inner face and toward the opposing sides, the fixed couplings being adapted to couple with a removable coupling which is inter-connectable in a first installed condition between a respective one of the fixed couplings of the panel and a respective one of the fixed couplings of an adjacent further panel. A panel assembly including at least two panels and a removable coupling is also disclosed as well as a system and method including interchangeable panels and couplings that allow for the formation of trenching supports in a variety of geometric configurations.

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.

This design is for wall and slope stabilization where the soil is stabilized by modified rebar placed in trenches excavated into the soil. The soil mass is supported by a series of grouted trenches. By excavating a series of trenches at designed locations and elevations in a soil mass where a slope and/or retaining wall is planned. The discontinuous trenches subdivide the mass into small segments thus reducing the anticipated load on the wall face or improve the stability of the soil slope. Discontinuous trenches filled with angular debris around modified steel rebar which will function as horizontal anchors for improved stability. The final step is to grout the trench fill. This will accomplish three things. First it will solidify the trench fill into a solid steel reinforced mass. Secondly, the rebars can be attached to the wall face as tie back anchors. Solid discontinuous trenches improve slope stability.
