    摘要:

    结合广州市十涌西路顶管工程设计、施工案例,介绍市政排水工程顶管顶进施工工艺原理和关键技术点,包括顶进工艺原理、针对不同土质条件顶进施工的要点、顶管顶进过程中的测量技术、顶管顶进过程中的纠偏方法以及控制要点,并通过工程实际得出监测结果:地表沉降最大累计量仅为6.5 mm,地表沉降最大速率1.2 mm/d,验证了在复杂的地质条件下,采取相应的措施并严格执行测量纠偏技术,能够适应地质变化,确保顶管施工的安全性和可靠性。

    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.
