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.

- Artificial intelligence has successfully been used in a wide range of fields including medical diagnosis, stock trading, robot control, law, scientific discovery, video games and toys. Frequently, when a technique reaches mainstream use it is no longer considered artificial intelligence, sometimes described as the AI effect. It may also become integrated into artificial life.
- Q: Does anybody have a product to make tires puncture free, specially ag machinery tires?
- try okorder or just call your local equipment dealer You local John Deere dealer will always be able to help
- Q: I would like to start building some home projects and do small crafts, maybe work on some small furniture projects. I would like this to last me a long time.
- The Hitachi portable table saw is the best that I have used. Pretty much most brands are nearly the same in weight and have the same features, but the table on Hitachi's saw is a little bigger. That makes cutting larger items easier.
- Q: During viral R/DNA replication, do viruses take advantage of the cell's ordinary error checking mechanisms?
- I think it depends on the virus. Many virus contain their own DNA / RNA polymerases that they use to replicate. Retroviruses for example have reverse transcriptase which synthesizes DNA from RNA, something that is not used by anything else. Not being proofread is what has allowed viruses to thrive, because it causes mutations that host organisms have to adapt to. Notice how there's a new flu shot every year? That's caused by antigenic drift.
- Q: I want to sign up for a construction machinery rental company! What should I do? Steps? How much do you charge for a year?
- Registered company each link required statutory time limit: check the normal circumstances within 2 working days to inform the result; account injection of bank procedures according to the provisions of the bank, usually in the 3 working days; verification under normal circumstances within 7 working days of the business license of the statutory time limit for 3 working days of audit group, tax registration certificate the statutory time limit for 30 working days to complete the registration fee: 1500 yuan single registration
