Application of Hard Cut Occlusion Pile in Complex Soft Soil Layer with Confined Water

摘要:

通过上海某水厂基坑的咬合桩围护施工，分析了在含承压水的复杂软土地层中采用全套管全回转钻机进行硬切割成孔的咬合式排桩施工易出现的问题，以及采用的相应施工措施和施工要点，保证了工程的施工质量，为以后类似工程施工提供借鉴和参考

Abstract:

Through the enclosure construction of occlusion pie for a foundation pit in a waterworks in Shanghai, the problems easy to occur in the construction of hard cut pore-forming occlusal row pile by a full casing rotary drilling machine in the complex soft soil layer with confined water are analyzed, and the used relevant construction measures and construction essentials are expounded in order to guarantee the construction quality of the project and provide the reference for the construction of the similar projects.
