Reservoir capable of regulating water flow of waterfall and regulating method

Abstract

The invention discloses a reservoir capable of regulating waterfall water flow and a regulating method, and belongs to the technical field of hydraulic engineering. The invention proposes that a reservoir is built in the upstream of a waterfall, a lower dam culvert pipe used for regulating the reservoir storage capacity and drainage flow is arranged on a dam, the lower dam culvert comprises flood discharge culvert pipes, working culvert pipes and sluice gates thereof. In the dry season, all sluice gates of the reservoir are closed in the non-enjoyment period of the waterfall, and the reservoir accumulates water resource for the waterfall. In the enjoyment period of the waterfall, the sluice gates of the working culvert pipes are properly opened to deliver water to the waterfall in a balanced manner. When ample flow water or draw off floodwater appears, all the sluice gates of the culvert pipes are closed, partially opened or all opened for accumulating water or discharge flood, so as to accumulate the maximum amount of water resource for the waterfall. In the enjoyment period of the waterfall, the sluice gates are properly opened for regulating discharge capacity, so that the expected water flow and balancing property of the waterfall in the later stage rainfall interval are improved, the waste of water resource is avoided, and the landscape quality of the waterfall is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering. Background technique [0002] Waterfall is a beautiful natural landscape. The landscape effect lies in the momentum of the waterfall, which is mainly determined by the drop, width, and especially the water flow of the waterfall. The water flow of the waterfall is very uneven under natural conditions. When there is abundant water flow or flood in the upstream precipitation, the waterfall will form a spectacular momentum. During the dry season, the amount of water is insufficient, even causing the waterfall to stop flowing and disappear. As a result, the viewing quality of waterfalls is not good or bad. Waterfall viewing is generally during the day, and the viewing time is generally only about one-third of a day and night. That is, only about one-third of the water forms an ornamental resource between day and night, and the other two-thirds of the water flow away in vain during no...
