摘要
部分小水电站受地形地质等条件限制,取水口不得不布置在河道凸岸,引水防沙成为该类电站首要解决的关键技术之一。文章以洼垴电站为依托,通过模型试验,观察水流流势、流态及坝前淤积形态,提出了在凸岸上游开挖明渠引水到取水口,利用上游来水冲沙的工程措施方案,达到了防沙的目的。
For some small hydropower stations, the water intake has to be arranged on the convex bank given special topographic and geological conditions, and the problem of water diversion and sediment control is on the top priority to be solved. The paper takes Wanao Hydropower Station as an example to address the problem. Model test is done to observe flow pattern and deposition feature in front of the dam. It is proposed to divert flow to the water intake through an open channel upstream the convex bank and to sluice sand by flow from the upstream.
