    7/15/2020  Working of Tunnel Boring Machine: This machine contains dozens of steel blades that chip away at the soil ahead as it rotates and the cutter-head sits at the very front of the TBM (Tunnel Boring Machine) and uses disc cutters. To allow the machine to move forward, these head-cutters do most of the hard work by spinning and digging away at the earth, and to keep the TBM progressing at a ...

  • Tunnel boring machine - Wikipedia

    OverviewHistoryDescriptionBack-up systemsUrban tunnelling and near surface tunnellingA tunnel boring machine, 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 to 17.6 metres to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs. TBMs
