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.
- Q:To what extent did machinery help people? To what extent did machinery hurt people, especially organized labor?Im talking about the first time machienry became more known to people and how did it affect them?

- Q:I have an assignement where I have to explain how ribosomes in plant cells are equivalent to a machinery in a city.I understand the concept and the general idea, but I don't know how to word it out and explain it clearly.Any ideas?Thanks!
- ribos keep the body moving and working, just like machinery in a city. it takes the garbage truck picking up the trash, delivery trucks bringing in fresh produce, police cars keeping the peace, construction machinery building new structures and so on so the city continues to function as a whole. when one piece of machinery breaks down it causes a chain reaction that affects thru out the city. same goes for your mind and body. good luck

- Q:What are it's advantages and disadvantages in both commercial farming and subsistence farming?
- Good question Advantages of Commercial Farming Can generate cash, the products are therefore intended to be marketed for profit. An extra profit is needed to fund the next cropping activities. A positive impact on an economy, unemployment decreases more people and resources are fully utilize and as a result government generates more revenue through taxes which makes an economy of a country more powerful. Disadvantages of Commercial Farming is that only certain crops would be produce as it has more money value. Peoples' would not get a variety to choose. Advantages of Subsistence Farming The people who worked there can get the food and it is a quite cheap as compare to Commercial Farming where excess of money is required to operate the farm whereas in subsistence farming you just have to buy a little piece of land and little money to be spend on the crops. Disadvantages are there is no proper source of income in this farming system. Difficult to buy seeds for new crops due to a cash-flow problem. A farmer has to work hard to yields the crops. Hope this helps and I think you are a student, if is it so then I am sure with this answer you would get 100% :)

- Q:Hello! I'm trying to get a little more tuned, get a little slimmer. My question is really about muscle machines, for example, legs, arms, etc. can make a beefy instead of slimmer? I also wonder how I get the inner thighs o forearms less. I am a girl at 166 cm o 60 kg and am not exactly great, but it feels like it could be better. Thanks for the answer!
- Hello! It's a myth that muscles become beefy so called. muscle machines. For the muscles to become beefy requires extreme training and specific programs. What happens when you train muscular strength is that your muscles get stronger and your metabolism in the body improves. Therefore, I warmly recommend that you practice with muscle machines. Yours sincerely, mobile
