A process for installing a modular retaining wall is illustrated and described having open or closed polygonal modules with channels disposed therein. The wall is set at least partially below a surface, the surface either being land-based or aqueous-based, and interfaces therebetween, e.g., shoreline. The modules of the wall are fastened to each other by respective fastening mating fasteners. The retaining wall is installed by a process employing a fluid-assisted internal mandrel.

The invention relates to a soil working device for creating a substantially vertically running hole in the ground, which hole is provided with a slurry, said soil working device having a base body, a connection apparatus which is arranged on an upper end region of the base body, and a soil removal apparatus and/or a soil displacement apparatus, which is arranged on a lower end region of the base body. According to the invention is intended that, at a lower region of the base body, a first pressure measuring apparatus for measuring a first ambient pressure is arranged, and that at an upper region of the base body, which is vertically spaced apart from the lower region, a second pressure measuring apparatus for measuring a second ambient pressure is arranged. The invention also comprises a method for creating a substantially vertical hole in the ground by means of such a soil working device.

A shoring system for controlling liquid on a site comprising a plurality of slide rails and a plurality of lateral plates. The plurality of slide rails comprise at least one liquid-controlling slide rail comprising a hollow body and lateral openings permeable to liquid when the at least one liquid-controlling slide rail is positioned into the ground. The openings are positioned on at least a portion of the liquid-controlling slide rail directed outside of the excavation. Each of the plurality of slide rails comprises at least two plate rails. Each of the plurality of lateral plates can be slid into the plate rails of two adjacent slide rails of the plurality of slide rails.

A retaining wall (10) is disclosed having multiple piles (11) and multiple panels (12) mounted uprightly to the piles for lateral, pivotal movement. Each panel has a body portion (13) and an end hinge (22) mounted to each side end (18). Each hinge includes hinge barrels (23) adapted to conform with the laterally opposing hinge barrels and spaces (24) located at the opposite end of another panel.
