WebThese earth retaining support provide high structural support and water tightness. 6. Prefabricated Diaphragm Walls. Prefabricated diaphragm wall construction uses the same principle as the above method with bentonite-cement suspension in the trenches. The prefabricated panels are placed inside the trench and the slurry mixture is set. WebShoring uses various support systems to prevent soil and the trench walls from moving. There are different kinds of shoring systems, but timber and aluminum hydraulic are the two basic types. Aluminum hydraulic cylinders are the most common type of shoring, and they are typically installed using spot bracing, plywood, or stacked methods.

WebDiaphragm walls (commonly known as D-walls) are concrete walls, typically cast in situ, formed within a trench supported by a slurry (most commonly, but not always, a bentonite suspension) during excavation. The concrete is placed into the trench, displacing the slurry and forming a concrete wall in direct contact with the ground.
