| Abstract: | In this paper,the project of the circle feeding water pipes of a power plant in Guangdong province is using to invest the construction technology of jacking pipes.While meeting the backfill of medium coarse sand layer accidentally in the process of jacking pipes,we grouted cement slurry to the excavation cabin to improve the nature of soil from air pressure balance tool tube.In full air pressure conditions,circle feeding water pipes are jacked and succeed in passing through the backfill of medium coarse sand layer. |
