Abstract
The utility model provides a bottom grid barrier type small dam with fish passing function, which comprises a bottom grid barrier; one side of the bottom grid barrier is a grouted stone dam surface, the top of the bottom grid barrier is provided with a trash rack, and two ends of the trash rack are respectively provided with a concrete dam top platform; a plurality of uniformly distributed fish passing channels are longitudinally excavated on the grout stone dam face, and a plurality of uniformly distributed rest grooves are transversely excavated; the fish passing channel is communicated with the rest groove, and the rest groove is filled with a filling agent. The utility model opens a longitudinal fish passing channel on the traditional masonry dam body, and also arranges a transverse fish passing rest groove for small fish passing dams with weaker migration capacity; due to the design of the resting groove, the situation that the oyster stones or the silt are taken away due to the torrent can be avoided, and a proper sheltering and resting space is provided for the fish passing through the dam; the top of the fish passing channel is arranged in a dam passing section and a trash rack in a layered mode, so that the fish passing through the dam is prevented from entering the trash rack by mistake and entering a water turbine, and the fish passing effect is prevented from being influenced.
Description
Technical Field
The utility model relates to a possess small-size dam of end check fence formula of crossing fish function belongs to ecological hydraulic structure technical field among the hydraulic and hydroelectric engineering.
Background
In the prior art, Chinese patent with application number 2016105596443 discloses a low-water-head ecological fish-crossing dam transformation method and structure, the structure is provided with a fish-crossing channel on a small dam body with a low water head to help fishes to cross the dam, the core technology of the structure is to open a notch channel at the downstream of the dam body as the fish-crossing channel, but the fish-crossing channel is longitudinally excavated at the dam body, and a transverse rest groove communicated with the fish-crossing channel is designed for the midway rest when the fishes migrate to cross the dam, so that the fish-crossing efficiency is improved, and the structure is completely different from the structure.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a small-size dam of end check fence formula that possesses fish function, this small-size dam of end check fence formula that possesses fish function is through reforming transform traditional stone masonry end check fence dam, under the prerequisite that does not influence dam body safety, realizes the fish function of crossing of the small-size dam of end check fence.
The utility model discloses a following technical scheme can realize.
The utility model provides a bottom grid barrier type small dam with fish passing function, which comprises a bottom grid barrier; one side of the bottom grid barrier is a grouted stone dam surface, the top of the bottom grid barrier is provided with a fish passing platform, the trash rack and the fish passing platform are arranged in a layered mode and are placed below the fish passing platform, and two ends of the trash rack are respectively provided with a concrete dam top platform; a plurality of uniformly distributed fish passing channels are longitudinally excavated on the grout stone dam face, and a plurality of uniformly distributed rest grooves are transversely excavated; the fish passing channel is communicated with the rest groove, and the rest groove is filled with a filling agent.
The fish passing channel is connected with the fish passing platform at the top, and the trash racks and the fish passing platform are arranged in a layered mode.
The length of the concrete dam top platform is 1/5 of the length of the trash rack.
The filling agent consists of gravel and silt to form a substrate structure.
The thickness of the substrate structure is less than the depth of the resting groove.
The beneficial effects of the utility model reside in that: a longitudinal fish passing channel is formed in a traditional masonry dam body, and a transverse fish passing rest groove is formed for small-sized fish passing through the dam with weak migration capability; due to the design of the resting groove, the situation that the oyster stones or the silt are taken away due to the torrent can be avoided, and a proper sheltering and resting space is provided for the fish passing through the dam; the top of the fish passing channel is arranged in a dam passing section and a trash rack in a layered mode, so that the fish passing through the dam is prevented from entering the trash rack by mistake and entering a water turbine, and the fish passing effect is prevented from being influenced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-fish passing channel, 2-rest groove, 3-masonry dam surface, 4-filler, 5-trash rack, 6-concrete dam top platform, 7-bottom grid dam and 8-fish passing platform.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1, a small-sized dam with a bottom grid barrier for fish passing comprises a bottom grid barrier 7; one side of the bottom grid barrier dam 7 is a grouted stone dam surface 3, the top of the bottom grid barrier dam is provided with a fish passing platform 8, the lower layer of the fish passing platform is provided with a trash rack 5, and two ends of the trash rack 5 are respectively provided with a concrete dam top platform 6; a plurality of evenly distributed fish passing channels 1 are longitudinally excavated on the grout stone dam face 3, and a plurality of evenly distributed rest grooves 2 are transversely excavated; the fish passing channel 1 and the rest groove 2 are communicated with each other, and the rest groove 2 is filled with a filling agent 4.
The fish passing channel 1 is connected with a fish passing platform 8 at the top, and the trash racks 5 and the fish passing platform 8 are arranged in a layered mode.
The length of the concrete dam top platform 6 is 1/5 of the length of the trash rack 5.
The filling agent 4 consists of gravel and silt to form a substrate structure.
The thickness of the substrate structure is less than the depth of the resting groove 2.
Examples
As mentioned above, the bottom grid type small dam with the fish passing function firstly excavates a plurality of fish passing channels 1 along the longitudinal direction of the dam body, transversely excavates a plurality of rest grooves 2 paved with stones and silt as bottom structures along the dam body, the rest grooves 2 provide rest places for fish passing through the dam, and secondly, the fish passing channels 1 are mutually communicated with the rest grooves 2.
Specifically, the fish passing channel 1 is connected with the fish passing platform 8 at the top, and the trash rack 5 and the fish passing platform 8 are arranged in a layered mode, so that the fish passing through a dam can be prevented from mistakenly entering the trash rack 5 and entering the water turbine.
