Microtunneling

A highly automated method of trenchless construction of underground pipelines. This method consists of tunneling using a drilling shield with simultaneous jacking of conduit pipes, with the entire process being almost completely automated. It is a one-stage pipeline technology.

The jacking is controlled by a special articulated head, with its position changed by means of hydraulic control cylinders.

We execute tunnels in the range of diameters from 400 mm to 4000 mm, with AVN and MH type machines
