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
The present invention relates to the hydraulic engineering technical field.
Background technology
Waterfall is a kind of natural landscape of beauty, and landscape effect is the waterfall imposing manner, and mainly by drop, the width of waterfall, especially discharge determines.Waterfall discharge under field conditions (factors) is very unbalanced.When abundance of water current or flood appearred in upstream precipitation, waterfall formed grand imposing manner.Water shortage between dry season, even cause the waterfall cutout to disappear.Cause the waterfall ornamental quality to neglect the excellent bad problem of neglecting thus.Waterfall is viewed and admired generally by day, and the time of viewing and admiring generally only is circadian about 1/3rd.A water yield of/3rd of namely only having an appointment between round the clock forms views and admires resource, and other 2/3rds the water yield is is then viewed and admired time diffluence in vain non-.The out-of-control trickling naturally of waterfall current causes the wasting of resources, influences the waterfall appreciation effect.
Summary of the invention
The present invention is directed to current trickles naturally, cause the wasting of resources and the problem that influences the waterfall appreciation effect, a kind of reservoir and regulate and control method of regulating and control waterfall discharge proposed, it is characterized in that reservoir is built in the waterfall upstream, dam arrange regulation and control pondage, waterfall discharge and flood discharge the dam under culvert pipe.Culvert pipe comprises flood discharge culvert pipe and small-bore work culvert pipe and the gate thereof of larger caliber under the dam.The flood discharge culvert pipe is by keying gate retaining or flood discharge, but and back work culvert pipe regulation and control waterfall discharge.The work culvert pipe is by keying gate retaining and regulate and control waterfall discharge, and can assist the flood discharge of flood discharge culvert pipe.Between dry season, reservoir is closed whole culvert gates in the non-time of viewing and admiring of waterfall, for waterfall is accumulated water resource.Viewing and admiring the time of waterfall, appropriate unlatching work culvert gate, the flow of keeping in balance is the waterfall water delivery.When reservoir upstream precipitation forms abundance of water current or flood passage, the mode that culvert gate takes Close All, part to open or all open is regulated and control retaining, draining or flood discharge, water resource for waterfall deposit maximum quantity, improve later stage precipitation interim waterfall discharge and harmony thereof with expection, avoid water resource waste, improve waterfall view quality.
Advantage of the present invention is by build reservoir in the waterfall upstream, for waterfall is accumulated non-water resource of viewing and admiring between time and wet season.And view and admire time equalization for the waterfall water delivery.Reach and avoid water resource waste, increase discharge and waterfall imposing manner, improve the purpose of waterfall quality.
The specific embodiment
The dam retaining forms reservoir.Dam mainly is made of water retaining structure and discharge structure.The reservoir that the present invention proposes is the special-purpose reservoir of accumulating and regulate and control waterfall discharge.The waterfall of China is in nearly source area, sprout or the intermountain streams of rivers mostly, run-off is less, required reservoir capacity amount is also little, and culvert pipe can satisfy the needs of retaining, flood discharge and regulation and control waterfall discharge under the dam as long as arrange, and need not to build other discharge structures such as sluice.Because low water discharge differs greatly with abundance of water current and flood passage flow, abundance of water or the flood discharge of a precipitation process formation are often also big than the run-off between dry season a few days.The water yield is less between dry season, and the number of times of the daily keying of gate opens and closes often many than flood discharge.Therefore reservoir drainage should arrange culvert pipe and gate thereof under the dam of two kinds of different bores, to adapt to the different needs of flood discharge and daily regulation and control discharge.Wherein heavy caliber flood discharge culvert pipe is mainly used in flood discharge, but flood discharge culvert pipe also back work culvert pipe regulation and control waterfall discharge under the abundance of water condition.Small-bore work culvert pipe is used for the daily retaining of keying gate and the draining that day alternates with night, and the work culvert pipe also can be assisted the flood discharge of flood discharge culvert pipe.Between the dry season of water yield shortage, sometimes need be with the reservoir emptying, so that water resource was fully used on the same day before every day, the time of viewing and admiring finished.So culvert pipe should maintain an equal level with the riverbed under the dam, reservoir does not stay minimum capacity of a reservoir.Reservoir regulation and control waterfall discharge need be considered retaining, the draining under retaining, draining and the low water condition under the abundance of water condition respectively.Annual limited number of times and of short duration relatively precipitation process form very big abundance of water or flood runoff, its enforcement are accumulated can be the abundant water resource of precipitation interim deposit twice.By implementing the drain discharge regulation and control, can improve the wet season and dry season waterfall landscape water flow harmony, make waterfall view quality relatively stable.
Because the waterfall current mostly are rivers sprout or intermountain streams, the dry season run-off is little.View and admire time barrier gate retaining in that about 2/3rds waterfall round the clock is non-, can be waterfall and view and admire next day and to increase about two times waterfall landscape water resource, improve waterfall view quality greatly.Concrete regulate and control method between dry season is: view and admire time appropriateness unlatching work culvert gate at waterfall, be the balanced water delivery of waterfall, and emptied reservoir on the same day.Closed shutter retaining when the time of viewing and admiring finishes is viewed and admired for the waterfall of next day and to be accumulated water resource.
The plentiful water resource of waterfall view is mainly from rainy season.Compare with dry season, the rainy season precipitation amount is big, and precipitation is intensive at interval.And no matter rainy season or dry season, when as long as abundance of water current or flood passage appear in upstream precipitation or snow melt, whether reservoir all can be according to the expection warehouse-in water yield, reservoir capacity amount with in conditions such as the times of viewing and admiring, the mode of taking Close All, part to open or all open to culvert gate under the dam is regulated and control water retention capacity or is drained off floodwater, and is the water resource of waterfall deposit maximum quantity.View and admire the time by opening service valve or partly opening floodgate assistant regulating and controlling waterfall discharge simultaneously at waterfall, later stage precipitation interim waterfall discharge and the harmony of raising and expection improve waterfall view quality.
