Abstract
In the case of a method for laying pipelines in the ground, a drill-hole is produced along a laying line, from a starting pit to a target pit, by a drilling head at the start of a pipeline, the drilling head being connected to a laying vehicle on the ground surface via a narrow vertical connecting device. The soil dislodged by the drilling head is removed from the drill-hole and conveyed to the surface. The force required for the drilling and laying operation is applied by the laying vehicle and/or by a feed device in the starting pit.
