The mud-water balance pipe jacking machine can be used under conditions of high groundwater pressure and a wide range of soil quality. Generally, the pipe diameter is between φ800mm and φ4000mm. It is a kind of full-cut cutting soil. The mud pressure is used to balance the earth pressure and groundwater. Pressure and mechanical automatic pipe jacking construction equipment that uses mud water as conveying spoil medium. The mud-water balanced pipe jacking system is mainly composed of a pipe jacking head, a ground operation console and other auxiliary equipment. The machine head has a PLC control box. The ground operation console gives action signals to control the movement of the machine head. The dredging system removes the spoil, the crane lowers the pipe, and the pipeline is jacked in by the hydraulic main jacking system.
The mud-water balanced pipe jacking machine construction has little disturbance to the soil around the pipe jacking, and it is easy to control the ground subsidence. It can achieve continuous excavation operations, fast jacking speed, simple operation, long service life, suitable for long-distance pipe jacking construction.
1. A wide range of applicable soils, including soft soil, clay, sandy soil, gravelly soil, hard soil, and backfill soil.
2. Strong crushing ability, large crushing particle size, and large number.
3. It has independent water injection and grouting systems.
4. The jacking speed is fast, the fastest jacking speed is 200mm per minute.
5, high construction accuracy, up, down, left, and right correction, the maximum correction angle of 2.5 °.
6. The ground centralized control system is adopted, which is safe, intuitive and convenient.
