ABSTRACT:
In a drilling device with a drive unit for rotation and advance the rod assembly has a plurality of pipe sections interconnected by means of plug-type connections torque proof in both directions. A tension rod protrudes through the interior of the rod assembling. The pipe sections are braced among each other with aid of the tension rod. The tension rod can be made of pipe sections or of a tension rope and allows the possibility, that the rope assembly can be moved in its integrity against the drilling direction.
