Abstract
An apparatus for making a second borehole in the ground, a cross section of which second borehole partially intersects a cross section of an existing first borehole, includes a boring device and a guide device operatively connected to the boring device. The guide device includes at least a first guide element configured to interact with a wall of the existing first borehole and a direction-influencing device configured to influence a direction of the second borehole while the second borehole is being made. The guide device is configured to guide the boring device relative to the existing first borehole.
