It is suitable for common ground and gravel layer condition, and the diameter of pipe jacking machine are from 1350mm to 3000mm. - details see: https://www.machineto.com/earth-pressure-balance-pipe-jacking-heading-machine-10113862

Mini Remote-controlled Slurry Balance Pipe-Jacking Tunneling Machine is a new advanced non-digging equipment with high technology. It combines multidisciplinary technologies in one, such as the

machinery units, hydraulic system, electric controller (including PLC),Laser system, measuring device, etc.

Used in the constructions of laying pipes underground, Pipe Jacking Machine has various advantages.

Besides the high efficiency, it also has no effect on the traffics on surface. Furthermore, it is good for the

environment, and can lower the cost of the construction. Due to its application of various new technologies

and adaptation to clay soil, sandy soil, and soil mingled with small pebbles or gravels.

1,To adapt to a wide range of soil,apply not only to the clay soil, but also suitable for medium coarse sand, strong weathering sand rock;

2,After the construction of ground settlement is small, can work in the overlying soil with only 1.5 times the diameter of the shallow soil layer;

3,A sound system for soil improvement, thereby expanding the scope of its use;

4,Opening rate reached 100%, earth pressure is more practical;

5,The center support cutting wheel, compact structure, light weight, long service life, convenient repair and maintenance;

6,The shaftless screw, screw conveyor out of soil from working face, thereby improving the height of opening and increasing the exclusion obstacle size;

7,Equipped with advanced control instrumentation, correction cylinder stroke and head back down, and the deflection can be digital display.;

8,Simple operation, flexible action, reliable;

9,With reliable main drive shaft sealing system.

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.
