Pipe Jacking And Site Test

The two different method have to be devised about the air-power pipe-jacking and the bigger caliber steel pipe. The former is so difference from the traditional pipe-jacking and the latter is so complex ,having so higher technology that they haven't being in use in practical working. To increase the practical application and extend the working field .the key is to introduce , study , prefect and improve the pipe-jacking technology in detail.To get the goal, the paper detailed presents the two types different pipe jacking building technology and site test about the bigger caliber steel pipe in the course of pipe jacking by engineering example; Propose the concrete way of improving and perfecting the new technology in the air-power pipe jacking; Make progress on applicability and spreading in use on pipe-jacking; Detailed indicates the earth-pressure balance theory and handling technology on the key technology of pipe jacking which Supply reference to pipe jacking construction in shanghai areac...
