The single-cutter head earth pressure balance pipe jacking machine can be used in soft and hard soil, which is a full-scale pipe jacking machine. The depth of covering soil is not high, Through reasonable grouting, the soil can be improved to maintain the stable surface and land subsidence. The deformation is very small, the transportation and handling of the spoil is convenient, simple； the working environment is good, the operation is safe and convenient, and it is suitable for large-diameter, long-distance pipe jacking.
Technical performance and features:
Wide range application : It is not only suitable for all kinds of soil, but also suitable for medium coarse sand, strong weathered, moderately weathered sandstone.
Low-speed and high-torque transmission mode, the cutting force of the cutter head is high, and the overload coefficient can reach more than 3 times.
There is an independent and perfect soil water grouting system, which can be used to modify the excavation surface.
The ground settlement is only 1.5 times of the pipe diameter.
by screw conveyor, highly excavated with large particle size.
Full-face cutting, the opening rate is 100%, and the earth pressure is more realistic, thus expanding the scope of application.
