Tunnels — The Boring Company

In circumstances where a utility is located deeper, the tunnel depth is increased accordingly. No disruptive surface vibration or noise during tunneling: once a tunnel boring machine is below approximately two tunnel diameters, or 28 feet, the tunneling process is almost impossible to detect, especially in soft soil. The tunnel operation is inaudible, and there is typically more surface vibration

Tunnel Boring Machine: Working of the Tunnel Construction

A tunnel boring machine (TBM), also known as mole, is employed for the construction of tunnels in hard or soft rock strata. The cutting process utilizes the rotation of the cutterhead (geared with disc cutters) and the blade pressure for excavation on the face of rock. Mostly, gripper and shield TBMs are ideal for tunneling in difficult rock
