1) The pressure slurry can be stabilized in the excavation face in the stratum which is easy to occur.
2) The slurry pressure transfer speed is fast and uniform, and the control precision of the balance soil pressure of the excavation face is high, and the disturbance of soil around the excavation face is small, and the control precision of the ground settlement is high.
3) Applicable to weak the mucky clay layer, loose sand layer, gravel, cobble layer and hard soil interface layer formation. Without special soil improvement measures, circulation of slurry, adapt to the geological conditions. It is especially useful in stratum water content reached, above the water more Jiang tunnel and subsea tunnel.
4) Cutter, cutterhead wear abrasive is small, easy to long distance shield construction.
5) Muck excavated conveyed by slurry pipeline, fast and continuous, reduce transportation amount of motor vehicles, fast construction progress.
6) The residue in the transport to the surface will not be exposed before the tunnel with high cleanness.
7) Cutting noodles and concrete filled with mud and the tool, cutter to lubrication and cooling effect, small frictional resistance, mud mixing is small resistance and cutterhead torque is small, more suitable for large diameter tunnel construction.
1) Fill layer, cohesive soil layer, silty soil layer, sand layer, gravel layer, mudstone, mmudstone formation.
