Φ8080mm Earth Pressure Balance Shield Machine

Description:

1) Excavation diameter is large, suitable for high-speed inter city rail transit tunnel construction.

2) Keep the earth pressure, maintain the soil of excavation face stability, construction safety.

3) In the loose aquifer in construction of deep buried long tunnel technology and good economy etc.

4) Special measures such as soil improvement and other special measures can be taken in permeable stratum such as sandy soil, and the adaptability of geological condition is good.

5) Keep the earth pressure, speed control, and maintain the cutting volume of excavated volume phase equilibrium, the surface subsidence control precision.

6) Shield machine's advance, unearthed, assembled lining and so on the entire process to realize the automation work, the construction speed is quick, the labor intensity is low.

7) Construction site is small, does not affect the underground pipelines and other facilities, the construction of no noise and disturbance, the impact on the ground traffic is small.

Applications:

1) Artificial earth fill.

2) Silty clay, mushy soil, fine sand, medium sand, coarse sand, round-gravle layer and silt under quaternary strata.

3) The rock stratum for halo weathering, high weathering and weak weathering of conglomerate sandstone and pebbly sandstone under paleogene system.
