Theslurry shield machine supports the working surface through mud pressure,digging the soil by cutter, transported by mud pump. The separated mud ispumped back to working surface, pressed into the cutter through cyclicrotation, so the tunnel surface forms during one time. It could control the stabilityof working surface easily, adapting well to different geological conditions, sothat its widely used in tunnel construction of high land groundwaterpressure, river bottom and submarine.

Pipejacking machine is widely used in digging and laying various channels such asurban underground drainage pipes, gas pipelines, communication cables.
☆mts1000：It is applicable forshort distance pipeline construction with middle and small diameters（rig construction systems and masonry construction systems.）
☆mts2000：It is applicable forcomplicated geological tunnel construction with large diameter, long distanceand small turning radius（Rig construction systems,construction of earth pressure systems, mud construction systems, hard rockconstruction systems, hybrid construction systems）
This technology does not need to dig the surface. Jack the pipeinto the earth through working well, which could also cross as a curve in orderto avoid some underground pipeline or obstacles.
Open TBM is mainly used in good rock conditions,without large fracture zone, faults and groundwater. It could play theadvantage while working with complete and steady surrounding rocks. Especiallywhile digging among the hard rock and mid-hard rocks, the great supporting systemoffers enough force to push the cutter, which helps the open TBM to observe theopened rock surface directly, so as to describe the geological condition ofopened tunnel conveniently.
Double(Single) shield TBM is applicable for geologicalcondition of mountain with various rocks. The rock field is with a certain ofstability, so that it does not need to balance the working surface. It is withthe characteristics of high digging speed and well-formed tunnel. As for some good geological conditions, we don’tneed to assemble segments. We could use rocks as supports. Compared with thetraditional tunnel digging technology, the double( single ) shield TBM includesthe advantages of forming tunnel surface during one time, supporting andbuilding in the same time, constructing with safety and reliability, goodworking environment, less extra-digging amount, digging faster and costingless.
