Abstract (en)
[origin: US4798501A] The flexible earth anchor useful for reinforcing underground structures such as a traverse is insertable in a hole in the ground to a certain depth and is attachable with the walls of the hole at its end facing the deepest portion of the hole or along its entire length. Advantageously an adhesive means is used for the attachment. The anchor is constructed from a plurality of lamella in close contact with each other and slidable against each other. Advantageously the lamella are made from sheet metal in a continuous manufacturing process and are attached together by welding. They can be spread out at their inserted end in the hole to provide a better bond to the adhesive and held together by a ring. A sleeve can be provided at the chamber end which is attached by welding to the lamella and which can be used to rotate the earth anchor during the adhesion process.
