Abstract
The percussion tip (4) is moved axially in a reciprocating manner during ram boring. The displacement cone (9) sitting on the percussion tip (4) serves to radially displace the earth for forming a channel in the earth, e.g. for laying conduits. The entire implement is thus moved in the driving direction during ram boring and is pulled back in the opposite direction during removal from the formed channel. So that the displacement cone (9) is not released from the percussion tip (4) during the axial movements of the implement in both the driving direction and the opposite direction, these two components (9, 4) are provided with threads (13, 33) and are screwed to one another. In addition, these two components (9, 4) can also be provided with a conical bore on the one hand and with a conical stem (12) on the other hand, the cone being tapered in the driving direction, so that, during the driving of the implement, the displacement cone (9) is supported both via the threads (13, 33) and via the cone (12) at the percussion tip (4).
