APPARATUS AND METHOD FOR MAKING BOREHOLES IN THE GROUND, THE CROSS SECTIONS OF WHICH BOREHOLES PARTIALLY INTERSECT

摘要

Apparatus (100, 200) for making a second borehole (2) in the ground, the cross section of which borehole partially intersects the cross section of an already existing first borehole (1), comprising a boring device (8) and, operatively connected to the boring device (8), a guide device (9) for guiding the boring device (8) relative to the already existing first borehole (1), wherein the guide device (9) comprises at least a first guide element (13) which interacts with the wall of the first borehole (1), wherein the apparatus comprises means which make it possible to influence the direction in which the second borehole is made while it is being made.
