超长隧洞单钻孔多支渗压计安装埋设施工方法研究

Research on the Installation and Burying Construction Method of Single Drilling and Multiple Branch Seepage Pressure Gauges for Ultra Long Tunnels

超长水工隧洞不同部位同一方向上安装多支渗压监测传感器是当下水利水电工程安全监测主流的技术解决方案,隧洞洞顶竖向朝天孔内安装布设多支渗压传感器也成了当前水利水电工程监测技术领域普遍面临的问题。通过研究实践证明该施工方法具有安装简便、实时高效、缩短工期、节约生产成本等的优点。

Installing multiple seepage pressure monitoring sensors in the same direction at different parts of an ultra long hydraulic tunnel is currently the mainstream technical solution for safety monitoring in water conservancy and hydropower engineering.The installation and deployment of multiple seepage pressure sensors in the vertical facing holes at the top of the tunnel has become a common problem in the field of water conservancy and hydropower engineering monitoring technology.Through research and practice,it has been proven that this construction method has the advantages of simple installation,real-time efficiency,shortened construction period,and cost savings in production.
