江口水电站左岸溢洪道T型浮塞式检修闸门技术研究与应用

Technical study and application of T-type floating emergency gate for left spillway of Jiangkou hydropower station

针对江口水电站左岸溢洪道闸门更换工程无检修闸门的情况,提出合理堵水方案保证施工。就增设检修闸门的技术方案进行了认真研究,对浮塞式检修闸门的结构设计和安装应用进行了论述,并根据实际情况对其进行了进一步优化,为类似工程设计提供参考。

s：Considering the situation that these is no emergency gate for gate replacement engineering at left spillway of Jiangkou hydropower station, reasonable water plugging plan should be advanced. This paper analyses the technical scheme of additional emergency gate, and discusses structure design and application of floating emergency gate. Meanwhile, the further optimization is studied, for reference.
