TBM (Tunnel Boring Machine)

The TBM technology is quite similar to  that of the micro-tunnelling and allows the realisation of  large and long-sized tunnels in any soil typology, by means of   a cutting head with the optional insertion of internal linings. The  range varies from  2 m  to 12 m  and can be used for the laying of pipes and for infrastructures  (example highway tunnels). The TBM machine is equipped with  a cutting head,  a guidance unit, pushing units, an electrical engine, conveyor belt for debris removal  , lifting appliances for  the lining units; the driving unit is next to the excavation front;  directional control is performed by means of a laser system.
