桩端后注浆施工工艺及应用
CONSTRUCTION TECHNOLOGY AND APPLICATION OF BEHIND GROUTING WAY FOR CAST-IN-PLACE PILES
【摘要】 阐述了桩端压力注浆桩的施工工艺,结合实例分析桩端压力注浆效果及后注浆桩的工作特性,指出桩端压力注浆不但提高了桩端承载力,桩侧摩阻力也得到较大提高。
【Abstract】 The technology of the base-grouting way for castin-place piles was expounded in this paper.The grouting effect and specialitys of base-grouting pile were analyzed through a real example.It shows that press grouting not only improved the bearing capability of pile base,but also improved the bearing capability of pile skin.
