A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling.
Tunnel Boring Machines For projects with difficult ground that still demand the speed of a Main Beam TBM Fractured rock can be an insurmountable obstacle if you buy the wrong machine.
The Best Products for Tough Jobs You won’t be alone when you buy a Robbins TBM. If you are planning to tunnel through rock, you want a TBM from a manufacturer who will support you as your partner throughout the project, anywhere in the world.
Single shield TBM. A single shield machine uses pre-fitted segments to exert the blast force on the working face. Digging time represents approximately 80% of operating time, the remaining 20% corresponding to segment fitting.
Ranked amongst the most important tunnel-boring machine manufacturers on the world market, NFM Technologies provides its customers with tunneling machines of 4 to more than 15 metres in diameter, suited to all types of geology, acknowledged for their reliability and robustness.
A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
