Description

{A prefabricated fish way structure}

The present invention relates to an artificial fishery structure in which various fishes are easily moved to upstream or downstream to protect an aquatic ecosystem and environment, and the assembly of fishes is firmly performed so as not to be lost during a torrential rain or flood. More particularly, A base concrete layer having a plurality of wedge balls formed at a predetermined interval in the fore and aft direction and a left and right wing walls vertically installed on both left and right sides of the foundation concrete layer; A water receiving wall vertically installed in front of the foundation concrete layer, and a body structure formed in the front of the water receiving wall; And a first fastening vane protruding from the front side and the rear side of the outer surface of the first block body so that the ends of the first fastening vanes come into contact with each other, And a second block body having a protrusion formed on an upper surface of the second block body, and a second fastening vane protruding from the front, rear, left and right sides of the outer surface of the second block body, A plurality of first and second fastening vanes are disposed adjacent to the upper surface of the base concrete layer so that their ends abut against each other, and the first fastening vanes are positioned between the blocks, and the end portions of the second fastening vanes are installed to overlap the upper end portions of the first fastening vanes The first and second fastening blades of the first and second fastening blocks are respectively inserted into upper and lower portions of the upper and lower fastening blades which are overlapped with each other and the lower portion is fixed to the wedge hole of the foundation concrete layer, And a connecting wedge for connecting the connecting wedge.

Generally, water or industrial water is secured by installing a water gate or a water gate in a river or an agricultural waterway, and the water or industrial water is divided into an upstream side and a downstream side of the river, and various fishes and microorganisms living in the river are divided into upstream There is a problem in that it is impossible to move from the downstream to the downstream or from the downstream to the upstream. Thus, conventionally, apart from the hydrants that regulate the amount of the fresh water, there has been a problem that an underwater ecosystem Respectively.

However, in the conventional art, since the width of the stream is narrower than that of the river and the river water flows along the slope, the flow rate in the island is very fast, so that it is difficult for the small fish to move upstream along the slope and the underwater ecosystem is destroyed. A technique has been developed and used to assemble the fish body through an artificial block having a concave / convex portion formed on the upper surface portion and to have a space in which fishes staying upstream can stay temporarily.

As a prior art related to the above-mentioned Eudoblock, in Korean Utility Model Registration No. 20-0235670, a front body partition plate and a rear partition wall are formed at the front and rear ends of a bottom plate, And an engaging plate is formed in a horizontal direction at the upper end to engage with a rear diaphragm of an adjacent block body, and protrusions are protruded at the center of the engaging plate, and recessed portions and connecting rings are formed at left and right upper portions of the bottom plate. However, the above-mentioned prior art is designed to be simple and bundled with a connecting ring of a neighboring block with a wire or the like through a connecting ring embedded in both left and right sides of the bottom plate, so that the connecting ring and the wire made of a metal are kept immersed in the water As a certain period of time passes, the rusty part of the connection is easily broken, and in the summer, There were problems that swept lost.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a foundation concrete structure which is constructed such that left and right wing walls are provided on both left and right sides of a foundation concrete layer, The first and second fastening vanes are integrally assembled so as to be adjacent to each other in the front and rear sides of the first block, The connection wedge is vertically inserted into a portion where the end portions of the wing are matched with each other and the first and second fastening vanes of the first and second fastening blocks are overlapped with each other so that the lower portion of the connection wedge is inserted into the wedge ball The first and second blocks are fixedly installed so that the first and second blocks are not connected to each other by the metal connection ring and the wire, And the connecting wedge is fixedly installed in the wedge hole of the base concrete layer through the first and second fastening wings of the first and second fastening blocks so that the assembly between the first and second fastening blocks is firmly established, And to prevent loss during flooding.

In order to accomplish this purpose, a foundation concrete layer having a plurality of wedge balls formed at a predetermined interval in the fore and aft direction is connected to a side of a waterway beam installed across a river, A waterproof wall installed vertically in front of the base concrete layer, and a main body structure formed by collecting water in front of the waterproof wall; And a first fastening vane protruding from the front side and the rear side of the outer surface of the first block body so that the ends of the first fastening vanes come into contact with each other, And a second block body having a protrusion formed on an upper surface of the second block body, and a second fastening vane protruding from the front, rear, left and right sides of the outer surface of the second block body, A plurality of first and second fastening vanes are disposed adjacent to the upper surface of the base concrete layer so that their ends abut against each other, and the first fastening vanes are positioned between the blocks, and the end portions of the second fastening vanes are installed to overlap the upper end portions of the first fastening vanes The first and second fastening blades of the first and second fastening blocks are respectively inserted into upper and lower portions of the upper and lower fastening blades which are overlapped with each other and the lower portion is fixed to the wedge hole of the foundation concrete layer, And a connecting wedge for connecting the connecting wedge.
