埃塞俄比亚TEKEZE水电站深孔弧门水封安装工艺改造

Installation Technique Reform of Deep Outlet Radial Gate Water Seal of Ethiopia TEKEZE Hydropower Station

埃塞俄比亚TEKEZE电站为潜孔式深孔弧门,设计水高头,水封的安装成为影响止水效果的关键。文章通过对此类闸门水封安装工艺的探讨,对存在渗漏隐患的局部位置进行了改造,并对原设计提出了改进方案,实践证明改造后水封安装质量优良、止水效果良好。

The radial gate of Ethiopia TEKEZE hydropower station is underflow aperture type deep outlet with high designed water head,the installation of water seal becomes the sticking point of influencing the water-stop effect.The paper makes probe on installation technique of gate water seal,and makes reform on the hidden trouble parts of leakage,and proposes reform plan on the original design,the reformed water seal obtains favorable water stop effect after putting into operation
