摘要
利用长锚索对竖井浅部进行加固。通过长锚索钻孔,将水泥浆注入竖井浅部松散岩体裂缝内,进一步提高了井筒周围松散岩体的稳定性,充分发挥了长锚索的锚固作用,有效控制了竖井岩体的变形,竖井浅部加固取得了成功。
In this paper,long cable anchor is applied in reinforcing the shallow part of the shaft.Cement slurry is grouted into the loose rock cracks in the shallow part of the shaft by the long cable drilling.It will further improve the stability of loose rock,give full play to the long cable anchor in the anchor role,and effectively control the rock deformation of shaft.It has obtained success in reinforcing the shallow part of the shaft.
