发明名称 Method and device for the direction-controlled feeding of pipes in accordance with the displacement principle
摘要 Lengths of pipe can be laid in the earth or can be pressed through the earth, in that excess earth is either transported away or is displaced to the sides and is compressed. For the direction-controlled feeding of pipes which are laid in accordance with the displacement principle, according to the invention, the displacement head is driven in a rotating manner when the direction is correct. As soon as the actual direction deviates from the desired orientation, the rotation is interrupted and the head is rotated into a fixed position such that a control surface guides the head back into the desired position during the compression feed. The respective orientation of the head is displayed in a monitoring station by means of an optical monitoring device, for example a laser beam.
