Pipeline laying method, involves centrically rotating cutting wheel of drill head around laying line while drilling, and applying required force for boring and laying process in starting cavity by laying vehicle and/or moving equipment

摘要

The method involves laying a pipeline (1) in a ground in which a bore hole is provided from a starting cavity (5) along a laying line (6) to an ending cavity by a drill head. The drill head is connected with a laying vehicle by a connecting device at a ground level (10). A cutting wheel of the head is centrically rotated around the laying line while drilling, where soil is loosened from the wheel, removed from the bore hole and extracted above the ground. Required force for boring and laying process in the starting cavity is applied by the laying vehicle and/or a moving equipment. An independent claim is also included for a method for laying a pipeline in a ground.
