type
Pipe Thruster

manufacturer
Prime Drilling GmbH

capacities

The pipeline is set-up on the surface on rollers and welded to the end of the mirco-tunneling machine.  The pipe is pushed into the borehole and excavation occur simultaneously.

It pumps the excavated material through a slurry circuit inside the prefabricated pipeline, to a separation plant located aboveground. The pipeline, which is laid out on the surface on rollers and welded to the end of the micro-tunneling machine, is pushed into the borehole at the same time as excavation takes place. The necessary thrust force is provided by the Pipe Thruster. It pushes the micro-tunneling machine forward together with the pipeline – with a thrust force of up to 750 tons in increments of 5 meters. The push force is transferred to the pipeline through the Pipe Thruster’s clamping unit and then to the machine’s cutter-head. During excavation, the tunnel face can be controlled consistently and safely using slurry-supported tunneling technology even in heterogeneous, water permeable soils. Uphill and downhill slopes, as well as curved drives along the alignment, can be managed precisely by guidance systems (U.N.S.).
