Abstract:Combining the design and construction case of the Guangzhou Shiyongxi Road Pipe Jacking Project, the principle and key technical points of the municipal drainage engineering pipe jacking construction process were introduced, including the principle of the jacking process, the essentials of jacking construction under different soil conditions, measurement techniques during the pipe jacking process, correction methods during the pipe jacking process, and control points. The monitoring results from the actual project indicate that the maximum cumulative surface settlement is only 6.5mm, with a maximum rate of surface settlement at 1.2mm/d. This verifies that by adopting corresponding measures and strictly implementing measurement and correction techniques, it is possible to adapt to geological changes, ensuring the safety and reliability of pipe jacking construction under complex geological conditions.
