高水位浅覆土泥水平衡顶管施工技术探讨

Discussion on Construction Technology of Slurry Balance Pipe Jacking with High Water Level and Shallow Cover

基于石家庄翠屏路顶管工程的实践经验,从井点埋设深度、埋设数量及顶力的合理确定等方面,对高水位浅覆土条件下井点法施工关键技术进行了深入分析,对施工工艺进行了优化,并提出了施工质量技术保障措施,解决了顶进过程中的技术难题。

Based on the construction experience of Cuiping Road in Shijiazhuang, crucial construction technology of well point under the conditions of high water level and shallow cover was deeply analysed from aspects of buried depth, point numbers and the determination of jacking force. The construction process was optimized. The technical measures for ensuring construction quality were put forward, and technical problems in jacking progress were solved.
