Description
Technical Field
The invention relates to a fish passing facility, in particular to a reinforced concrete frame rotating disc fishway for a medium-high water head.
Background
With the increase of ecological environment and fish protection consciousness, the construction of fish passing facilities such as fishways in water conservancy and hydropower engineering becomes a normal and important content. The fishway is an important facility for communicating a fish migration route, has unique advantages and efficacies in the communication migration route on the hydro-junction, and cannot be completely replaced by other fish passing facilities. In recent years, medium and high water head fishways gradually appear, and due to the fact that lines are long, water level amplitude is large, the fishways are located in high-mountain canyons, and site limitation is large, the challenges in the process of determining a fishway engineering scheme are more prominent, and a structural system of the medium and high water head fishways also becomes one of key points of fishway research and design.
The fishway which is implemented and finished in China at present is mostly applied to a low-water-head hub; the fish way mode is not generally adopted in the high-water head hub, firstly, the fish swarm travels for a long distance of several kilometers, is tired for a long time, and even can not reach an upstream reservoir after the exhausted energy; secondly, a high-head pivot is usually located at a narrow place and cannot be provided with a fishway on a plane; thirdly, the engineering cost is huge, often reaches billions or even more than billions, and the project is obviously unreasonable in economic efficiency. Therefore, whether the above problems can be effectively solved becomes an important factor affecting the development of the fishway with medium and high water head.
In the conventional medium-high water head fishway, two schemes of filling rubble concrete under the fishway and supporting the fishway by overhanging rock wall beams are adopted to raise the fishway to a sufficient height. The scheme of filling rubble concrete under the fishway has huge engineering quantity, and huge engineering cost and investment; the scheme that the fishway is supported by the overhanging rock-wall beam usually needs to dig a mountain and dig a wall, is difficult to construct and has higher requirements on the lithology of the mountain.

In order to solve the technical problems, the invention adopts the technical scheme that: a reinforced concrete frame rotating plate-lifting fishway for a medium-high water head comprises a U-shaped groove-shaped fishway which is in a shape of a square or a square and is rotated for multiple times to lift and a cast-in-place reinforced concrete frame for supporting the fishway, wherein a top plate of the cast-in-place reinforced concrete frame is used as a bottom plate of the fishway, the projections of fishways in each step in the vertical direction are mutually overlapped, fishway pool chambers are separated by slit clapboards, rest pools are arranged on the bottom slopes 1: 10-40 of the fishway pool chambers, all 90-degree and 180-degree turning positions are provided with rest pools which are flat bottoms, and the fishway which is rotated for multiple times to lift is rotated from a downstream water level to an upstream water level.
The rest pool is in a shape like a Chinese character 'yi' or 'L' at a 90-degree turning position; the U-shaped part is arranged at the 180-degree turning part.
The spiral lifting height of each step of the fishway is 3-6 m.
The invention has the beneficial effects that: rest ponds are arranged at all the 90-degree and 180-degree turning positions, so that the rest and the migration of fishes are facilitated; the frame structure ensures that the fishway occupies small area, is flexible in arrangement, light in structure and strong in adaptability, and can solve the problem of difficult fishway arrangement in narrow spaces in high mountains and canyons; the frame structure fishway construction has the advantages of small operation surface, small construction difficulty, small engineering quantity and low construction cost, reduces the engineering investment, brings good economic benefit, and realizes the coordinated development of economic benefit and ecological environment protection.
