<p>The device has a drawing unit (2) i.e. drill pipe, inserted into ground (6) from a starting point (3) along laying lines (4) to a target point (5) by a drawing device (1) i.e. horizontal drilling device. A front side of the drawing unit is connected with a wedge-shaped traction head. A pipeline (8) is attached at a rear side of the traction head. The traction head is moved into the ground by the drawing device to upwardly displace the ground. The traction head is controlled and steered by a vertical connecting device of a vehicle at the ground during laying process. An independent claim is also included for a method for laying a pipeline in ground.</p> |
