tunnel boring machine

Tunnel Boring Machine (TBM) can make the digged grit to be fluid and waterproof slurry, therefore, it is suitable for soft and loose earth, grit layer and various earth; The digging surface uses earth layer pressure to keep stability, which minimize its influence to the ground; the slurry can become a waterproof layer, which prevent the underground water flow into the machine; the remainning earth can be transported by conveyer belt, earth carriers and pressure pump, without big remnant earth handling equipment.
