三江口水电站扩建工程“越河取水”设计

The Design of the Water-Intake Structure across the River of the Extension Project of the Sanjiangkou Hydropower Plant

介绍三江口水电站扩建工程"越河取水"建筑物,衔接竖井、过河埋管、汇合隧洞等的设计。三江口水电站扩建工程于2006年12月6日扩建第一台机组并网发电。至今电站运行已近8年,尤其经历2007年汛期的考验,目前整个取水建筑物运行正常,情况良好。

The paper introduces the design of the water intake structure across the river, including the snaft connection, the pipe embedding across the river and the joining to the tunnel. The first generating unit of the extension project of the Sanjiangkou hydropower plant was put into commercial operation and connect- ed to the power grid on December 6th, 2006. It stood the test of floods in 2007 and has operated for nearly 8 years to date. The whole water intake structure has been under proper operation.
