摘要
长螺旋钻孔灌注桩是一种新型的桩基础施工手段。使用长螺旋钻孔机施工既可以钻孔又可以压灌混凝土,避免多种机械设备交叉作业,操作简便,混凝土灌注速度快,成桩质量好。文章结合工程实际,对长螺旋钻孔灌注桩施工工艺要点及常见问题进行了探讨。
Long auger boring filling pile is used as a new construction technology for pile foundation.As it does both drilling and grouting concrete,it,known for easy operation steps,fast grouting speed and good piling quality,can save lots of mechanical work.The paper probes into the construction technology and some common problems of long auger boring filling pile with practical examples.
