Ground anchor

Abstract

A method for applying a pivoting ground anchor on considerable depth, the anchor including; a first coupling member for temporary coupling the anchor with a driving rod to drive the anchor to the considerable depth; and, a tension member for coupling the anchor to the object to be anchored, a second coupling member which fixedly couples the anchor to the tension member, wherein the tension member is of one piece and has a considerable length for applying the pivoting ground anchor on considerable depth, and wherein the method includes the step; continuously supplying the tension member to the ground anchor without interruption during driving the ground anchor to the considerable depth.
