Tunnel boring machine - Wikipedia

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. They can be designed to bore through anything from hard rock to sand. Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drillingra

Tunnelling shield - Wikipedia

A tunnelling shield is a protective structure used during the excavation of large, man-made tunnels. When excavating through ground that is soft, liquid, or otherwise unstable, there is a potential health and safetyhazard to workers and the project itself from falling materials or a cave-in. A tunnelling shield can be used as a temporary support structure. It is in place for the usually short time from when the tunnel section is excavated until it can be lined with a permanent support structure. The permanent structure may be ma
