摘要 |
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 a first guide element configured to interact with a first side of a wall of the existing first borehole facing the second borehole and a second guide element configured to interact with a second side of the existing first borehole remote from the second borehole. The guide device is configured to guide the boring device relative to the existing first borehole. |
