龙江水电站枢纽工程侧向漏斗式进水口设计

Design of Lateral Funnel-type Intake for Longjiang Hydropower Station Complex Project

龙江水电站枢纽工程引水系统进水口经过进水口位置、形式、引水洞线方案布置比较及其前沿高边坡的稳定分析,最终选用侧向漏斗式进水口形式,成功地解决了高边坡可能不稳定导致进水口堵塞等问题,避开了断层对引水隧洞高压岔管部位的影响,且洞线布置更为平直、顺畅,水头损失更小。

By comparing intake position, intake type and diversion tunnel axis layout schemes and analyzing the stability of high slope in front of intake, the lateral funnel-type intake is finally chosen as the water diversion system intake of Longjiang Hydropower Station Complex Project. This intake design eliminates the risk of intake blocking caused by high slope instability, and makes the axis of tunnel more straight and smooth, the head loss more smaller. Meanwhile, the intake design can avoid the influence of fa.uhs on high-pressure bifurcated pipe of diversion tunnel.
