The device is designed to be prefabricated and is of the type, which forms a bottomless case, which rests on the soil. It is produced as prefabricated panels (1), which are assembled together by means of struts (2), which are formed as rigid rods with ends (3) bent at right angles. The struts are used to regulate the distance between the panels forming each side of the wall. Each end of the strut is designed to be fixed to the panel by means of binding into the receptacles (4), which are fitted to project from the inner walls of the panels. The projections are provided with a hole (17), through which the end of the strut is passed to hold the panels square. The projections are arranged to allow the panels to be formed into end sections and also to form the end panels of the wall. |
