The jacking pipe sections are added to the advancing pipe string as usual, allowing the thrust forces of the jacking rig to progress the cutter head forward through the bore. The difference between these jacking pipes and conventional ones is that the special design allows them to be used as jacking pipes in the forward direction whilst Pipe Jacking Manned Techniques UNITRACC Hydraulic and Static Pipe Bursting UNITRACC Pipe Jacking Manned Techniques UNITRACC Pipe Jacking (Manned Techniques) Unmanned techniques Pipe Eating Pipe Jacking Manned Techniques UNITRACC The process differs from those mentioned above in that the bursting body and continuous pipe are driven with the aid of a jacking installation without the assistance of a cable winch and that all the working steps in the sewer are monitored by a sewer camera.

The jacking forces to be expended are comparable with the drive for a new sewer with the same outside diameter (see [Stein88c]).
