Pilot pipe jacking is used especially for the underground laying of smaller outer diameters in the DN 200 range. This method enables pipe laying in a resource-friendly way and independent of any preexisting building or structure.
To this end, in a first step, a pilot hole is bored, traditionally by using the soil displacement method. By turning the pilot pipe’s head, which has the shape of a tilted plane, a change in direction can be made and the desired grade and direction be ensured while the pipe is thrusting forward.
