摘要
溪洛渡大坝导流洞下闸蓄水后,右岸347 m高程AGR1灌浆平洞岩体出现明显渗水。长江科学院受业主委托进行封堵处理,根据实际情况布置孔位、确定钻孔角度,选择有效的阻塞方式及时封堵外渗的浆液,综合应用CW环氧树脂灌浆材料、LW聚氨酯灌浆材料及丙烯酸盐灌浆材料,按期完成了灌浆处理,取得了明显的封闭效果。
AGR1 grouting adit rock which located 347 m elevation of right bank leaked after impoundment of the reservoir of diversion tunnel of Xiluodu Dam. The Changjiang River Scientific Research Institute was entrusted for leakage treatment. Based on actual situation, hole position and drilling angle were determined, and the leaking grouting materials were plugged in time by effective blocking mode. CW epoxy resin grouting material, LW polyurethane grouting material and acrylate grouting material were comprehensive applied to ensure that the grouting was finished on time and obtained good sealing effect.
