Urządzenia do mikrotunelowania



Microtunnelling is a technology for horizontal steered drilling, which equipped with self-propelled hydraulic installation tubes are pushed through the chamber embedded in pushing home station.

The laser beam controlls the drills track, observed on the monitor by the operator of drilling equipment. Operation control is from the steering position located above the chamber start.

First part of the drilling head can be tilted within a few degrees from the axis of the tube follower circuit so that drilling can be readily corrected.

Drill head is made of a rotary blade and crusher excavation output. Transportation of excavated material is realized by means of drilling mud.
