The invention relates to a system for laying underground cables or underground lines in the ground near the surface, in a borehole (102) along a laying route (101) between a start point (100) and a target point (110), comprising a boring device (10) comprising an advancing head (12) for creating the borehole (102), a drilling rod (11) and/or a casing (14), wherein the diameter of the advancing head (12) is greater than the diameter of the casing (14) or of the drilling rod (11), so that an annular space (121) is formed between the borehole wall (102) and the casing (14) or the drilling rod (11) and the annular space (121) is provided with lubrication and wherein the advancing head (12) relates to a displacement drilling head (15, 16, 41) or a drilling head system (18) comprising a drilling tool (19) and a drilling tool drive (22) for loosening the ground.
A system for laying underground cables or underground lines in the ground near the surface, the cables or lines being laid in a borehole along a laying route between a starting point and a target point with a drilling apparatus, comprising;
A method for laying underground cables or underground lines in the ground near the surface, the cables or lines being laid in a borehole along a laying route between a starting point and a target point, comprising:
