Pipe bursting is an environmentally friendly method, which replaces old pipes nearly of all material trenchless in the same bore channel. The Cable Burster TERRA-EXTRACTOR bursts (cuts) the old pipe, enlarges the bore channel with the expander cone and pulls in the new pipe simultaneously.

For pipe replacement from manhole to manhole the the Cable Burster TERRA-EXTRACTOR is positioned on top of the first manhole. The manhole accessories are assembled in the manhole for the pulling cable. The short pipes are assembled in the second manhole. The short pipes are connected to the expander cone by means of PIPe rods and the rear tensioning plate. Each PIPe rod is the same length as a short pipe. For assembly of a new short pipe another new PIPe rod is simple screwed on manually. The PIPe rod is tensioned. The assembly of a short pipe system is typically twice as fast as the speed of conventional systems (patented).
