Present stage, along with increasingly increasing of high dam object of construction production, the ecological problem thereupon brought also more and more highlights.In the middle of numerous ecological problem, the most serious on the impact of Habitat for Fish environment with the deep-water low-temperature of high dam reservoir area.Because dash dam body is higher, before dam, reservoir water level is very dark, and its degree of depth is generally at more than 100m, and some even can reach 200-300m.Therefore, the temperature difference between the surface water before dam and swallow is caused larger.And on the other hand, the hydro plant intake position of each high dam engineering is different.If intake water level is comparatively dark, then cause fetched water temperature lower, cause that to drain into the water temperature of downstream river course by power station too low.And for the shoal of fish under natural river course, the water temperature under its living environment generally all needs constant in a zone of reasonableness.Therefore, the low temperature water body that power station drains into downstream river course very likely can destroy the living environment of the shoal of fish and other biological colony in nature river course, causes its amount of survival to decline to some extent.For this reason, for hydroelectric project, certain engineering measure need be adopted, realize the stratified pumping in power station, to ensure the hydrobiological normal existence environment in downstream.
At present, Stoplog gate adopts maximum stratified pumping hydraulic structures, and it has the features such as swift and convenient to operate, stability is high, safety is good, is widely used in the middle of all kinds of high dam engineering.So-called Stoplog gate is the provisional hydraulic structure adopting the method for in layer stacked Liangmen to fetch water, but it still needs complete gate slot and supporting structure thing.Therefore, for Stoplog gate, it just should take in and design in the project planning stage.But, many power stations put into effect not corresponding Stoplog gate of planning construction at present.For this kind of power station, if reset Stoplog gate, then need redesign for its concrete engineering and build Stoplog gate, and in the middle of building course, need reservoir emptying just can complete construction.Like this, not only can expend higher Stoplog gate construction cost, and the emptying of reservoir can cause the tremendous economic of generating electricity and irrigation water to lose in work progress.For this reason, a kind of concept of flexible buoyancy aid dam is suggested, to replace effect of traditional Stoplog gate.This buoyancy aid dam utilizes multiple buoyancy aid to jointly control the particular location of dash curtain, to realize the object of different water level condition lower leaf water intaking.It is simple that it has structure, and easily manufactured, quick construction, does not affect the features such as reservoir filling (also can construct under retaining operating mode), have a good application prospect.But such building has a huge design defect, i.e. the dismounting of dash curtain and the problem of replacing.For such building, because anchor structure is positioned at bottom, therefore once dash curtain occurs to destroy or floating thing before serious fill dam, could take out after bottom anchor body need being removed and change curtain.And being positioned at the bottom because of bottom anchor body, its dismounting probably needs reservoir area emptying.Obviously, this certainly will cause further economic loss.For this reason, the application proposes a kind of flexible dash curtain of underslung water conservancy project of new structure, it adopts suspension type to replace floatation type to carry out dash operation, while the advantage with flexible buoyancy aid dam, achieve freely dismantling and changing of dash curtain, improve the Practical Performance of such water retaining structure.
Summary of the invention
The object of the invention is for above-mentioned existing problems, a kind of flexible curtain of suspension type controlling reservoir stratified pumping is provided, the flexible curtain structure of this suspension type is simple, built environment requires low, all can construct under reservoir area retaining and water-less environment, dismounting is simple and convenient with Renewal process, improves the Practical Performance of flexible water retaining structure greatly
Technical scheme of the present invention:
A kind of flexible curtain of suspension type controlling reservoir stratified pumping, be made up of top mooring anchor, mooring anchor slideway, sliding anchor, top pulling force anchor cable, bank slope mooring anchor, middle part pulling force anchor cable, dash curtain and suspention counterweight, two top mooring anchors are separately fixed at bank slope top, upstream two, two sides side slope arranges two mooring anchor slideways respectively, two sliding anchors are arranged on two mooring anchor slideways and by hydraulic pressure or mechanical system in the enterprising line slip of anchoring slideway and location, pulling force anchor cable two ends, top are fixed with two sliding anchors respectively; Two bank slope mooring anchors are individually fixed in the lowest water level place of two sides side slope middle, and the two ends of middle part pulling force anchor cable are individually fixed on two bank slope anchor points; Dash curtain is that multilayer non-woven geotextile is made, and dash curtain upper end is fixed in top pulling force anchor cable, and middle part and middle part pulling force anchor cable are fixed, and the equal interval suspention in bottom counterweight, suspention counterweight is concrete structure.
The invention has the beneficial effects as follows:
