Method for plugging rail transit engineering investigation drilling hole
The invention discloses a method for plugging a rail transit engineering investigation drilling hole. The method comprises the following steps of (1) chambering on the ground; (2) brushing adhesives on the wall and the bottom of the hole; and (3) filling layer by layer: filling investigation hole cores in the lowest layer, then filling a cement-sand mixture, finally, filling an asphalt cold-mixedmixture and compacting. The method has the advantages of easiness in operation, good hole sealing effect and high safety.
本发明公开了一种封堵轨道交通工程勘察钻孔的方法，包括以下步骤：1.在地面扩孔；2.在孔壁和孔底刷粘合剂；3.分层填充，在最下层填充勘察孔岩心，然后再填充水泥砂土混合料，最后再填充沥青冷拌混合料并压实。本发明操作简单，封孔效果好，安全性高。
