description A device for driving holes is provided with a crankshaft on which accommodated on respective crankspins with a provision for free rotation, is a cone-shaped member at the front end followed by a succession of tapered rollers which are the transverse parts of a conically shaped body. The apparatus is provided with means ensuring its longitudinal travel in the hole. When the crankshaft is rotated, the cone-shaped member and tapered rollers start rolling over the wall of the hole, gradually enlarging the latter and compacting the wall by laterally displacing the ground. The device is capable of driving holes with a diameter as large as 800 mm in any compactable ground thus, producing firm and stable walls.
