注浆补强在大直径钻孔灌注桩断桩接桩中的应用

摘要

通过注浆补强接桩工艺在大直径钻孔灌注桩断桩接桩工程实例中的应用，介绍了施工中钻孔布置的原则，并对注浆量控制、浆液配置、分次注浆间歇时间及注浆终止条件等作了较详细的介绍，为该技术的推广应用提供技术支撑。%Through the application of grouting compensation pile connecting technology in large-diameter bored pile broken pile connection engi-neering,the paper introduces its drilling distribution principles,and describes its grouting amount control,slurry distribution,grouting intervals and grouting ending conditions and so on,which has provided technological support for promoting the technology.
