摘要
通过工程实例介绍钻孔灌注桩后注浆工艺及效果,分析后注浆技术提高桩侧摩阻力和桩端摩阻力的机理,灌注桩后注浆技术是一项工艺简单,投资少,能提高经济效益的施工技术。
This paper illustrates process and effects of base pressure-grouting and pressure-grouting along pile of engineering practis. The mechanism Of improving the end bearing resistance and frictional resistance of drilled cast-in situ by the pressure grouting is analyzed. The technigue is simple process,low cost and high benefit which is worthy of use widely.
