Soft Ground Cat TBMs consist of a Cuttinghead, Forward Shell, Stationary Shell, Trailing Shield. When the tunnel face does not require a continuous and pressure balanced support, the TBM is operated in ?Open Mode?. The face is mechanically supported by the cuttinghead while the flood control doors regulate muck flow from the face to the cuttinghead chamber. The excavated muck is rapidly extracted by the belt conveyor.
Cat Soft Ground Non-Pressurised TBMs can be used to install a variety of Tunnel linings including:
- bolted segments
- Rib & Lagging
- Pipe (concrete, steel, Hobas?)
