Soft Ground TBM

A Soft Ground TBM (Tunnel Boring Machine) is a specialized machine designed to excavate tunnels through loose, unstable soils like clay, silt, or sand. Unlike hard rock TBMs, it uses a cutting head to grind through soft ground and relies on a pressurized shield and supports to prevent the tunnel from collapsing. It typically employs methods like pressurized gravel or slurry to stabilize the tunnel face and manage water ingress. This technology allows safe, efficient tunnel construction in challenging soft ground conditions, minimizing surface disruption and ensuring structural stability during the process.
