Challenges in a Long-Distance Pipe Jacking and Solutions in China
Pipe jacking, for its incomparable technical superiority, has been gaining wider and wider application in municipal construction project. However, there are many difficulties in terms of construction techniques and the long-distance pipe jacking is one of the most complicated. This paper, with the case history of the first and second stage of the sewage disposal project in Chongqing, presented the comparison and selection for the optimal construction scheme of long-distance pipe jacking, the installation techniques of pipe-jacking equipments, pipe-jacking construction method, technical challenges and possible solutions. The result of the study shows that long-distance pipe jacking technique, if carefully designed and combined with information construction, can be widely applied to the construction of municipal infrastructure in China.
