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 safety hazard to workers and the project itself from falling materials or a cave-in. A tunnelling shield can be used as a temporary support structure.
