Method for laying portion of line underneath ground surface, involves guiding line in concavity to allow laying of portion of line underneath ground surface, and washing portion of line with liquid and/or gaseous medium
The method involves producing a concavity in ground underneath a ground surface, and guiding a line in the concavity to allow laying of a portion of the line underneath the ground surface. The portion of the line is washed with liquid and/or gaseous medium e.g. water and/or air. The guidance of the line in the concavity is executed after completion of production of a portion of the concavity. A displacement body is partially led against a direction in the concavity during guidance of the portion of the line into the concavity, where the displacement body includes a soil displacement hammer. An independent claim is also included for a device for laying a portion of a line underneath a ground surface.
