黄金埠电厂的补给水源为信江,取水方式为岸边开敞式无坝取水.采用动床物理模型试验,对黄金埠电厂补给水取水口局部区域的水流、泥沙运动及地形冲淤规律进行研究,在确保电厂取水能力的前提下预测了可能的冲淤程度,并在此基础上对取水泵房挡沙坎高程进行了优化.试验结果表明,拟建取水泵房进水口底坎接近枯水主槽河底,岸边贴流状况良好,且取水口前的断面基本没有冲淤变化,取水泵房的选址和设计合适;泵房取水流量不会影响河道枯水期通航;将泵房挡沙坎高程抬高0.5m能够最大限度地避免取水口淤积,有利于电厂取水口的安全、可靠运行.
The supply source of Jinbu Power Plant is Xinjiang River, and the water-taking method is open-shore non-dam water intake.Using the dynamic bed physical model test, the law of water flow, sediment movement and terrain scouring and sedimentation in the partial area of the water supply outlet of the Jinbu Port Power Plant Based on the above analysis, the elevation of sand pumping ridge in the intake pumping station was optimized, and the results showed that the bottom of the water intake of the proposed pumping station was nearly dry The main channel bottom of the waterway and the shoreline afforestation are in good condition, and there is basically no change in erosion and sedimentation in the section before the water intake, and the site selection and design of the water pumping station are suitable; the water intake flow rate of the pumping station will not affect the navigation during the dry season of the river channel; The elevation of Sankan elevation 0.5m can avoid siltation of water intake to the maximum extent, which is good for safe and reliable operation of power plant water inlet.
