Elementary Analysis on Application of Sleeve-valve Pipe High-pressure Jet Grouting in Pipe Jacking Construction Precipitation
Huang Haisong;Duan Tengteng;Ming Daoxuan;
As a kind of trenchless pipeline construction technology, pipe jacking is widely used in municipal engineering because of its superiority not affecting the ground traffic. However the artificial excavating pipe jacking technology will encounter various problems in the practical engineering application. Combined with a project case, and according to the characteristics of the engineering project, the water-stop curtain method of sleeve-valve pipe high-pressure rotary jet grouting is used in the design of light well point precipitation in order to provide the guarantee for the smooth construction of rainwater pipe jacking, and to prospect some referencing values for the design and construction of the similar projects.
