文章详细介绍了甘肃省白龙江橙子沟水电站引水隧洞调压井衬砌后,出于进度、安全原因,将原设计方案进行优化,将原设计的垂直井壁固结灌浆改为竖直方向环绕井壁固结灌浆,采用自上而下分段深孔固结灌浆方法进行施工,成功解决了进度、安全等施工难题,对以后类似工程施工有很好的借鉴作用。 After the lining of the surge shaft surge tank of Bailongjiang Orange Zigou Hydropower Station in Gansu Province has been described in detail, the original design scheme was optimized for the reasons of schedule and safety. The vertical grouting of the vertical borehole wall was changed to the vertically oriented borehole wall Consolidation grouting, using top-down subdivision deep hole consolidation grouting method for construction, the successful solution to the progress, safety and other construction problems, for similar projects in the future have a good reference.
