Abstract (en)
[origin: US7942609B2] A method for trenchless pipe laying, a pipeline is constructed form a starting point to a goal point undercrossing an obstacle wherein the constructing of a bore hole and laying the prefabricated pipeline, which is constructed in one piece on the surface, are done in one work step, wherein at the front end of the pipeline a steerable drilling device is arranged, wherein a pipe thrusting device is arranged at the starting point applying forces from the outside to the pipeline via traction preferably friction by pushing the pipeline from a starting point to a goal point, wherein at the same time the necessary contact forces for drilling are transferred, wherein the cuttings produced during the drilling by the drilling device are removed and transported hydraulically out of the bore hole via a transport line inside the pipeline, and wherein the annular space between pipeline and bore hole wall created during drilling is continuously filled with a drilling suspension.
