The slurry balance shield machine is mainly applicable to the excavation of sand geological strata with large underground water pressure and large permeability system. Its working principle is that it injects mud with appropriate pressure into the sealed chamber of the diaphragm in front of the support ring to form a mud film on the excavation surface, support the front soil body, and cut the mud film on the surface of the soil by the cutter installed on the cutter head, and mix it with the mud water to form high-density mud, The slurry is transported to the ground for treatment by the slurry pump and pipeline, and the whole process is uniformly managed by the automatic control system of mud and water balance established in the ground central control room.

Our slurry balance shield machine has a diameter of 6.0-9.5m, and we welcome the industry colleagues to choose and buy it.

The characteristics of slurry balance shield machine are as follows:

1. It can stabilize the excavation surface in the stratum prone to quicksand, and can operate under normal atmospheric pressure without using the pneumatic method;

2. The transmission speed of muddy water pressure is fast and uniform, the control accuracy of balanced earth pressure on the excavation face is high, the interference to the surrounding soil around the excavation face is small, and the control accuracy of ground settlement is high;

3. The shield excavated soil is transported by muddy water pipeline at a fast and continuous speed;

4. The transportation volume of the battery truck is reduced, and the construction progress is fast;

5. The tool and cutter head are small in wear and easy for long-distance shield construction;

6. The cutter head bears less torque, which is more suitable for the construction of large-diameter tunnels;

7. Large-scale muddy water treatment equipment and sites with muddy water treatment equipment are required.
