Earth Pressure Balance Pipe Jacking Machine

High flexibility to work in wide range of soil quality, especially for coarse sand, weathered and strong weathered sandstone. Applying low speed, high torque transmission methodology to boost the cutting force. The overload factor can reach 3 or above. The independent, comprehensive soil injection, and grouting system can improve the excavation face soil condition. The construction land subsidence is small, the minimum overburden can be only 1.5 times the diameter of the smallest. Using central support type cutter, compact construction, light weight, long life, and easy maintenance. Using screw conveyor transfer soil, the altitude is high and the particle size is large. Head of the pitch and the deflection angle using advanced electrical system control, easy operation, responsive, corrective amount digital display. intuitive and reliable. Full section cutting, and the opening rate can be reached to 100%.
