The single-push disc earth pressure balanced pipe jacking machine can be used in soft soil and hard soil, and it is an all-earth pipe jacking machine. The depth of the compound soil is not high. The minimum diameter is 1.5 times the diameter. Through reasonable grouting, the soil can be improved and the ground subsidence of the stabilizer on the control surface can be maintained. Minimal deformation, convenient and simple transportation and disposal of spoil, good working environment, safe and convenient operation, suitable for large diameter and long distance pipe jacking.
1. Suitable for a wide range of soils: Not only for various soils, but also for medium coarse sand, strong weathering, and weathering sandstone;
2. It adopts low-speed and high-torque transmission method, the cutter head has high cutting force, and the overload coefficient can reach more than 3;
3. There is an independent and perfect soil water injection and grouting system, which can improve the soil on the excavation surface, thereby expanding the scope of application;
4. The construction ground settlement is small, and the minimum soil layer is only 1.5 times the pipe diameter;
5, using a center-supported cutter head, compact structure, light weight, long life, easy maintenance;
6. Unearthed by screw conveyor, with high unearthed height and large particle size;
7. Deviation correction angle is 2.5 degrees, and the head's pitch and knitting adopt advanced control system, which can be displayed digitally, easy to operate, sensitive in action, intuitive and reliable;
8. Full face cutting, full opening rate, earth pressure is realistic.
