摘要
通过对冲钻孔灌注桩后注浆技术工作机理的分析,探讨后注浆技术设计的主要内容,及施工中应注意的技术问题和关键要点,结合后注浆技术在福州卵砾石层中的应用实例及效果,为后注浆技术更广泛的应用提供借鉴与参考。
Through the analysis of the working mechanism of post grouting technology for punching bored pile,the author discusses the main contents of the design of post grouting technology,and the technical problems and key points that should be paid attention to in construction.Combined with the application and application exemples of post grouting technology in the gravel layer of Fuzhou city,the wide application of post grouting technology can be used for reference.
