The mud-water balance pipe jacking machine can be used under the conditions of high groundwater pressure and a large range of soil quality. Generally, the pipe diameter is between φ800mm-φ4000mm. It is a kind of full-section cutting of the soil, and the muddy water pressure is used to balance the earth pressure and groundwater. Pressure, muddy water is used as a mechanical and automated pipe jacking construction equipment for transporting spoil media. The mud-water balance pipe jacking system is mainly composed of a pipe jacking head, a ground operating table and other auxiliary equipment. There is a PLC control box inside the head, and the ground operating table gives action signals to control the movement of the head. The sludge discharge system removes the spoil, the crane lowers the pipe, and the hydraulic main roof system pushes the pipe in sections.
The construction of the mud-water balance pipe jacking machine has little disturbance to the soil around the pipe jacking, easy to control the ground settlement, can realize continuous excavation operation, fast jacking speed, simple operation, long service life, suitable for long-distance pipe jacking construction.
1. It is applicable to a wide range of soil quality, including soft soil, clay, sand, gravel soil, hard soil, and backfill soil.
2. Strong crushing ability, large crushing particle size and large number of crushed pieces.
3. With independent water injection and grouting system.
4. Fast jacking speed, the fastest jacking speed is 200mm per minute.
5. High construction accuracy, up, down, left and right deviation correction, the maximum correction angle is up to 2.5°.
6. The ground centralized control system is adopted, which is safe, intuitive and convenient.
