论注浆堵水施工技术在输水隧洞工程中的应用

Application of Grouting and Water Plugging Technology in Water Conveyance Tunnel Project

在输水隧洞施工过程中,渗漏水问题非常普遍,为有效减少涌水量,提高围岩稳定性,文中以东山供水工程石盘乡段9-3#控制主洞段工程为例,对渗漏水段采用注浆堵水施工技术进行处理,详细介绍了设计方案、施工工艺等。结果表明,注浆堵水施工技术能很好地解决输水隧洞施工过程中的渗漏水问题,对类似工程施工有一定的借鉴意义和参考价值。

Water leakage is very common during the water delivery tunnel construction. To effectively reduce the water inflow and improve the stability of surrounding rock,9-3# control section of the main tunnel project in Shipan township section of the Dongshan Water Supply Project was taken as an example. Grouting and water plugging technology was adopted to treat the leakage section. Design scheme and construction technology were detailed introduced. The results show that the grouting and water plugging technology could solve the leakage problem in water conveyance tunnel construction,and provide reference for similar projects.
