大直径桩桩端注浆加固施工技术

Technique of Reinforcement by Pouring Slurry from One End of a Large Stake

针对大直径桩施工中存在的承载力不足质量问题,通过工程实例介绍,分析产生的原因,提出桩端注浆处理方法,并探讨桩端注浆提高单桩承载力的机理。

In view of the fact that large diameter stakes are not strong eno ugh during construction,I will present my solution to this problem by giving som e examples,analyzing the cause,suggesting the method of pouring slurry from one end of a stake,and discussing the mechanism of enhancing the bearing strength of a single stake by using the method mentioned above.
