A method for and inserting a ground anchor into the ground, comprising the step of screwing an elongated anchor body into the ground by means of an extension tube that is to be connected to the proximal end of the anchor body. The distal end of a tension line is connected to the anchor body above the screw blade turns. A pipe sleeve is slid onto the extension tube, while guiding the tension line via an eyelet at the pipe sleeve adjacent to the distal end of the pipe sleeve, from the anchor body along the pipe sleeve. The anchor body is then screwed downwardly by turning the extension tube and the pipe sleeve jointly to a predetermined depth. Finally, the pipe sleeve together with the line extending there along are rotated around the stationary anchor body/extension tube assembly.

[ I claim:] [1.] A method for inserting a ground anchor into the ground, comprising the steps of:connecting an extension tube to a proximal end of an elongated anchor body;screwing the elongated anchor body into the ground by means of the extension tube having proximal and distal ends;rotating the anchor body until the anchor body reaches a first predetermined depth;connecting one end of a tension line to the anchor body at an attachment point between the two ends of the anchor body;sliding a pipe sleeve having a distal end over the extension tube, while threading the tension line through an eyelet that is fixed adjacent the distal end of the pipe sleeve and guiding the tension line in an upward direction along the pipe sleeve;rotating the extension tube and the pipe sleeve jointly until the anchor body reaches a second predetermined depth;holding the extension tube to prevent further rotation of the extension tube while continuing rotation of the pipe sleeve so as to cause the tension line to be gradually pulled in a downward direction through the pipe sleeve and wind the tension line into a coil on the proximal end portion of the anchor body and/or the distal end portion of the extension tube.
