Embodiment Construction

[0005] The dam stores water to form a reservoir. Dams are mainly composed of water retaining structures and drainage structures. The reservoir proposed by the invention is a special reservoir for accumulating and regulating the flow of waterfall water. Most of the waterfalls in our country are located near the source of rivers, small tributaries or mountain streams. The runoff is small and the required reservoir capacity is also small. As long as the culvert pipe under the dam is installed, it can meet the requirements of water storage, flood discharge and regulation of waterfall water flow. Need, without the construction of other drainage structures such as floodgates. Due to the great disparity between the flow of low water and the flow of high water and flood discharge, the flow of high water or flood formed by one precipitation process is often larger than the runoff during several days of low water. During the dry season, the water volume is small, but the daily opening...

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...
