Microtunneling

Microtunneling

THIS TECHNIQUE USES A REMOTE-CONTROLLED GUIDED MICROTUNNEL BORING MACHINE (MTBM) TO LAY UNDERGROUND RIGID PIPELINES.

Microtunneling combines a pipe jacking technique with a remote-controlled boring or shield machine. The thrusting force is distributed by hydraulic jacks located in the MTBM front section and operated by a thrust ring.

Microtunneling can be used for underground pipe installation in any kind of geological conditions, even below groundwater, by means of a controlled-thrust, line and grade tolerance guaranteed system.
