Zusammenfassung: | A system for laying underground cables or underground lines in the ground near the surface, the cables or lines being laid in a borehole (102) along a laying route (101) between a starting point (100) and a target point (110) with a drilling apparatus (10), with an advancement head (12) for creating the borehole (102), and with drill piping (11) and/or a casing (14), characterized in that the diameter of the advancement head (12) is larger than the diameter of the casing (14) or of the drill piping (11), such that an annular space (121) between the borehole wall (102) and casing (14) or drill piping (11) is created, in that the annular space (121) is provided with a lubrication, and in that the advancement head (12) is a drilling-head system (18) made up of a drilling tool (19) and drilling-tool drive (22) for loosening the soil. |
