长螺旋压灌反插钢筋笼成桩工艺在吉大二院基坑支护工程中的应用

摘要

结合吉大二院基坑支护工程实例，论述了长螺旋成孔压灌混凝土成桩后反插钢筋笼的施工工艺，介绍了配套振笼器装置的反插钢筋笼工作原理及施工工法预案与解决方法。%Combined with the foundation pit engineering of Jilin University second hospital, the construction technology of inverse inserted steel reinforcement cage after long spiral press grouting concrete pile forming were discussed, the working principle, construction plans and solutions of the supporting cage device of vibration inverse inserted bar were introduced.
