earth pressure balanced pipe jacking machine, Model: DK1200-DK3000;, Motor power: 11*2-90*2KW*No. - details see: https://www.machineto.com/balanced-pipe-jacking-machine-10113902

DK type single cutter earth pressurebalanced pipe jacking machine.

Single cutter earth pressure balanced pipe jacking machine can be used in soft clay, and hard clay, it is all soil pipe jacking machine. The earth backing depth requirements is not high, at least 1.5 times of the pipe diameter. Through reasonable grouting method, it can improve soil, maintaining control surface stability and surface subsidence. Small deformation, the waste soil transport and processing is convenient, simple, good operation environment, safe and convenient operation, suitable for large diameter, long distance pipe jacking.

Technical characteristics:

1.Applicable to a wide range of soil: not only applies to all kinds of soil, but also suitable for medium coarse sand, highly weathered sandstone, moderately weathered sandstone

2.Adopting low speed large torque transmission method, cutter cutting force is high, the overload coefficient can reach above 3.

3.It has independent, perfect soil water injection and slip casting system, which can improve the soil mass of the digging surface, thereby expanding the application scope

4.the construction ground surface subsidence is small, the minimum soil backing layer is only 1.5 times of the pipe diameter

5.Adopting center support type cutter, compact structure, light weight, long service life, convenient repair and maintenance

6.Adopting screw conveyor delivering the soil, high soil excavating height, large granules diameter.

7.Correction angle is 2.5°. The Head pitching and deflection use advanced control system, digital display, convenient operation, flexible action, reliable.

Full end surface cutting, opening rate reach at 100%, earth pressure force is more practical.
