摘要
灌注桩后注浆技术是近几年在国内得到大力推广和应用的桩基础施工工艺,其意义在于通过增加少量人力物力的投入,可以使灌注桩成桩后的承载力提高30%～50%,从而产生较好的经济效益。
Post Grouting technology of bored concrete pile is in China in recent years to promote application and construction technology of pile foundation, the significance is that by adding small amounts of human and material inputs, can make the bearing capacity of bored pile after pile of improving 30%- 50%, resulting in abetter economic efficiency.
