DOUBLE SHIELD TBM
Product Category: Machines for tunnel construction / Tunneling machines
Continuous tunnelling at maximum speed
Double Shield TBMs are among the most technically sophisticated tunnel boring machines. They unify the functional principles of Gripper and Single Shield TBMs in one machine. Under stable geological conditions, the combination of methods allows for the installation of concrete segments parallel to tunnelling, achieving very high tunnelling performances. This powerful technology is therefore perfectly suited for excavating long tunnels in hard rock.
