Construction Technology Analysis of Long-Distance Jacking Prestressed Concrete Cylinder Pipe in Water Supply Project
Due to the limitations of terrain and construction conditions,long-distance water supply engineering pipelines often choose pipe-jacking construction.Jacking Prestressed Concrete Cylinder Pipes(JPCCP)are more commonly used when crossing railways,highways,and important buildings in the city.Taking the construction of a 318m-long JPCCP in a construction section of the Xin'anquan Water Supply Reconstruction and Expansion Project in Shanxi Province as an example,analysis and research have been conducted from various aspects such as preliminary preparation,jacking force calculation,and construction process control.This case could provide a reference for the application of long-distance JPCCP construction technology in hydraulic engineering.
