摘要
锦屏二级水电站进水口为独立岸塔式进水口,进水口底板低于河床高程。在进水口建筑物形成后,限制泥沙进入拦污栅后和闸前引水隧洞空间,以减少悬移质泥沙进入进水口基坑的总量,并采取措施在汛期有水状态下进行基坑淤沙清理,取得了较好的效果。
Intake in Jinping II hydropower station is a single intake tower. The intake bottom is lower than riverbed elevation. After building of intake structure,sediment is restricted to enter behind trashrack and in headrace tunnel before gate so as to decrease total amount of suspended load sediment which flow into foundation pit of intake. Some measures are taken during flood seasons to remove sediment from foundation pit.This practice will provide references to the similar sediment control and treatment projects.
