Description

Concrete-block for fish way of barrage

The present invention relates to an airway block for providing a moving passage for upstream and downstream fish families by smoothly descending a waterway descending in accordance with the installation of an underwater beam for intake in small and medium rivers, and in particular, the upper and lower blocks and the left and right blocks which are assembled in a stepwise manner. By increasing the structural stability by unifying the neighboring blocks with solid interlocking, by providing a resting space that maintains a certain depth even in the dry season, the free activity of the fish and the ecological environment are continuously secured, and the speed of the rapid flow is efficient. It is related to the underwater bore block which maximizes the aeration while attenuating the water, promotes the smooth image of the fish, enhances the natural purification effect of the water quality, and creates the dynamic river scenery.

Typically, small and medium-sized rivers are constructed with various types of transverse structures that control the water flow by blocking the flow of water across both eyes. The most widely constructed of these cross-sections is the concrete underwater beam (Barrage).

It is easy to understand that underwater beams are small concrete dams that prevent the flow of water, and the role of underwater beams is to temporarily trap water flowing downstream from downstream and store it for agricultural or industrial water storage. I'm in charge.

However, underwater submarines installed in rivers have the same net function as above, but they have the reverse function of destroying fish ecosystem.

In other words, when constructing underwater beams with concrete, the upstream and downstream streams are separated by high step and steep slope, which makes it difficult for fish stocks to move upstream of the stream, which leads to the ecological disruption of the fish family.

As a result, the ecological environment of various species of fish in the rivers is disturbed and the habitat environment is severely restricted. In particular, the anadromous fish returning to spawn cannot go back and upstream. There is a problem that results in the destruction.

In view of the above problems, in recent years, the fish way is connected to the downstream side of the underwater beams to promote free movement of fish.

Fisheries are categorized as terraced fishery, armored fishery, mechanical (elevator) fishery, etc. In the case of small and medium-sized rivers, terraced fishes are mainly installed in consideration of harmony with surrounding landscape while preventing riverbed scrubbing due to water flow.

By the way, the cascading fishes constructed in this way have no problem when the water flowing upstream of the underwater stream is always kept in a proper state at all times. However, in the dry season, the water flowing through the fishes loses its function as fish. In feng shui, the flow rate is so high that it is difficult for fish with low swimming ability to travel upstream.

Accordingly, the cascaded fish should have a structure to maintain a constant depth within the fishery and a structure to alleviate the rapids, and a quick construction is required due to the nature of the construction site of the river environment flowing water.

Recently, to build a cascading fish that meets the above requirements, the concrete fishery block made in advance in the factory, and then assembled and installed while connecting up and down and left and right in the field has been presented in various forms.

As a concrete fish block of such a concept, the fish block disclosed by domestic utility model registration numbers 20-0235671, 20-0263821, etc. are mentioned, for example.

In order to prevent the loss of the block due to the water of the river, the adobe block according to the above-described prior art constructs an integrated structure by tying adjacent blocks at the top and bottom and left and right sides with a wire-like binding line. In order to manufacture the factory, it is manufactured in the form of connecting ring in the body of the block.

In addition, it forms the overflow wall that protrudes upwards to attenuate water flow and cause aeration by acting like a shoal, and forms a hollow space in the body of the block to maintain a certain depth even in the dry season.

As a result, it is true that the structural stability of the fishery structure is secured, the fish are helped, and the natural purification of the water quality is improved to some extent.

However, although the above-mentioned blocks of the adobe according to the prior art are connected to neighboring blocks through the binding line, the binding force is insufficient only by the point coupling of the binding line, and the binding line is corroded as time passes after construction. Due to the breakage of the connection between the blocks is lost, in particular, because it is not taking measures to fix the bottom of the block to the riverbed there was a disadvantage that the stability of the block is threatened by torrents.

In addition, since the overflow walls formed at the front of the block block between the upper and lower blocks, the drop height between the upper and lower blocks is high and the steep slope is inclined, so that the fish species with weak force rising above the water are difficult to move upstream.

In addition, since the portion causing the aeration for supplying oxygen in the air is limited to the overflow wall, the aeration is insufficient, and thus there is a disadvantage in that it does not exhibit a satisfactory water purification effect.

Therefore, the above-mentioned adobe blocks do not provide enough functions and roles of the edo, and it was determined that the above-mentioned disadvantages should be compensated for. This is a problem that not only the above-described prior art but also other types of conventional blocks manufactured in the factory are commonly improved.

The present invention has been made to solve the problems of the conventional fishery block manufactured in the factory to build a cascading fishery downstream of the submersible beam, the object of the present invention is to block the upper and lower blocks and the neighboring blocks to the left and right assembled stepwise It is possible to provide a submersible bore block that can be held firmly without being lost in rapid flow by allowing the entire block installed while interlocking with a rigid structure to be organically interlocked and integrated.

It is another object of the present invention to provide a submerged fish block for ensuring a free activity of fish and a continuous ecological environment by providing a resting space in which a certain depth is maintained even in the dry season.

It is another object of the present invention to maximize the aeration while efficiently attenuating the flow rate of the rapid, thereby providing an underwater beam block capable of achieving a smooth image of the fish, enhancing the natural purification effect of the water and creating a dynamic river view. It is.

Still another object of the present invention is to provide a smoothly curved fish movement passage while having a small drop height between the upper and lower blocks, so that not only general fish species but also fish species having weak force rising above the water can easily move upstream. To provide.
