金沙江溪洛渡水电站进水口分层取水措施设计

为保证金沙江溪洛渡水电站运行期不同工况下进水口均能取到库区上、中层水,提高下泄水温,降低低温水对鱼类生长繁殖的不利影响,在招标阶段审定的单层进水口布置方案的基础上,通过调整取水建筑物设计形式,在鱼类主要产卵期(3—6月)采用叠梁门取到库区上、中层水,使鱼类集中繁殖期增温效果较明显,同时具备工程量小、投资省、运行操作灵活等优点。

Design of stratified water withdrawal structure of Xiluodu Hydropower Station on Jinsha River

In order to ensure that the water withdrawal structure of the Xiluodu Hydropower Station can extract the surface water and middle layer water under different working conditions,raise the discharged water temperature,and reduce the adverse effects of the low temperature on the growth and reproduction of fish,based on the original design of single inlet,the water withdrawal structure is adjusted to extract the surface and middle layer water using the stop log gates,so that the temperature increases significan...
