超长摩擦桩桩端桩侧联合注浆工艺研究

摘要

结合超长摩擦桩桩端桩侧联合注浆试验，介绍了桩端桩侧联合注浆时，L 形桩端注浆管和环形桩侧注浆管的设置方式，论述了桩端桩侧联合注浆的施工工艺流程，探讨了注浆管开塞和注浆参数的工艺控制措施，为今后超长摩擦桩后压浆施工提供参考。%Combining with extra-long friction Pile tiP and Pile skin joint grouting test,this PaPer introduced the set mode of L-shaPed Pile end grouting tube and circular lateral Pile grouting PiPe in Pile tiP and Pile skin joint grouting,discussed the construction Process of Pile tiP and Pile skin joint grouting,discussed the Process control measures of grouting PiPe Plug and grouting Parameters,Provided reference for extra-long fric-tion Pile Post grouting construction.
