Worldwide Leader in Forging, Tunneling & Drilling


Microtunnelling is a trenchless technology for the construction of pipelines and other high accuracy underground jobs using, as with TBMs, a boring head;

Starting from a launch shaft, the machine advances by pushing against the already laid pipes behind it with the help of hydraulic jacks. The operator, from an external guidance container, drives the machine with the help of a laser pointing system up to the reception shaft.

Besides their high quality consumables, the Palmieri Group can also supply machine upsizing kits, muck haulage systems and intermediate jacking stations in case of long drives.
