Description
Technical field
The present invention relates to a kind of water intaking of high dam reservoir engineering and water draw-offs, belong to hydraulic and hydroelectric engineering metal structure technology
Field.
Background technique
For reservoir, the function of water intaking and sluicing is generally required, two independent pipelines are usually set and are carried out respectively
Water intaking and sluicing, intake pipe are used to supply water to cities and towns, factory, industrial park etc., and tapping pipe is overhauled and given down for reservoir emptying
Swim ecological flow of releasing.The arrangement of above-mentioned intake pipe and tapping pipe, for fetching water and the farther away reservoir of sluicing interferometry difference
It is reasonable for engineering, the reason is that intake pipe excavates farther out with tapping pipe distance and casting concrete is mutually independent of each other.But
For fetch water and sluice arrange it is then unreasonable for reservoir engineering similar in orientation, because two independences are arranged in same close orientation
Pipeline, intake pipe are closer excavation and casting concrete with tapping pipe and can influence each other, and increase excavation and concrete sometimes
It pours difficulty and increases investment, it is more to increase investment particularly with the longer engineering of pipeline.Secondly, tapping pipe is vented for reservoir
It is less using probability, and be used for the more using probability of bleed downstream ecological flow, therefore directly release using tapping pipe, because
Sluicing operating valve drawoff discharge is larger, and power of motor highly energy-consuming is more, is unfavorable for energy-saving and emission-reduction.In addition, existing in intake
Emergency gate is set, in high dam reservoir engineering, if intake pipe and tapping pipe input elevation are too low, emergency gate design and fortune
Row head is excessively high, and gate moves water, and to close that there are risks larger, so existing technology or incomplete, up for further mentioning
It is high.
Summary of the invention
The purpose of the present invention is to provide a kind of water intaking of high dam reservoir engineering and water draw-offs, to reduce excavation amount
With concreting difficulty, cost of investment is reduced, decentralization flow-reduction energy consumption is rationally controlled by adding small-bore valve, is conducive to
