摘要
钻孔灌注桩后压浆法由于可大幅度提高单桩承载力、减少桩体沉降、节约成本等诸多优点而应用较快。分析了后压浆法提高桩基承载力的作用机理,介绍了后压浆法的施工工序和工艺。结合后压浆法在合肥某大楼钻孔灌注桩施工中的应用,提出了相关建议。
Bored grouting method can greatly improve the bearing capacity,reduce the pile settlement and cost,so it is applied very fast.This paper analyzes the mechanism of pile bearing capacity increasing with post-grouting method,and summarizes the construction process and technique of post grouting method.Finally,based on an example of application of post-grouting in a building bored piles in Hefei city,some proposes are put forward.
