KR200418616Y1 - A dual section block for fish way - Google Patents

Abstract

The present invention relates to a fish that is installed so that the fish can be freely moved from the downstream to the upstream in the beam installed across the river, the river pollution and ecological destruction due to the concrete pouring in the river for the installation of the fish is inevitably reduced The invention relates to an Adobe block configured in a block manner.

In general, rivers are installed across rivers for water intake and river maintenance, and the installation of rivers restricts the upstream and downstream movement of fish in the rivers, which causes habitat differentiation and threatens species persistence. In order to solve the problem of ecosystem disturbance caused by object isolation, a passage through which fish can move is installed in the beam, and the Ministry of Environment proposes a fishery type according to the characteristics of the fish and the fish type.

However, the cross section presented to the Ministry of Environment does not fully reflect the outflow characteristics of the river. In general, rivers that need to be installed in rivers are mid- and upstream regions, and the fluctuations in the flow rate occur seasonally. Not satisfied

In order to solve this problem, in the present invention, the shape of the cross section of the fish is composed of a semi-circular shape that can actively respond to the change in flow rate, and then the shape of the cross section is composed of the inclined surface.

In addition, the problem proposed in the installation of the fishery is the problem of river water pollution due to concrete pouring in the river, and to solve this problem, the present invention was devised as a factory block installed. In addition, depending on the block assembly method can be installed by replacing the existing beam as well as fish.

The present invention is directed to a double-sectional cross-sectional seam block that is improved to fit the flow characteristics of the river for fish flow passage.

Depending on the life style of the fish in the river, it can be divided into three categories: pure freshwater fish, sashimi fish, brackish fish, and fish fish. Generally, fish fish are installed around smelt fish, but pure freshwater fish are the main characteristics of fish. Due to the nature, it shows a characteristic to move upstream. However, it is obstructed by beams, so installation of the fish is necessary.

According to the type of fish, in the past, the full-flow quarterly type fish was the mainstream, but the flow rate and direction of water in the fish are very unstable due to the flow rate, so there is no place for small fish to rest in the fish. There is a drawback. Recently, an ice-harbour type cascade has been devised, in which part of the cascade does not overflow. Depending on the characteristics and the type of the fish, many types of fish, such as vertical slotted, denier, calverted, and fastened Designed. Therefore, the Ministry of Environment requires that the fishes of the wall type, terrace type, ice harbor type and vertical slot type are assigned according to the type of beams, fish and rivers. A standard section is presented.

However, existing fishes have their own characteristics, but the common form is that the basic frame of fishes has a rectangular cross-sectional shape. Although the rectangular cross section is efficient when the flow rate in the stream is constant according to the season, it is difficult to efficiently cope with the fluctuation of the flow rate with the simple rectangular cross section in the case of rivers with large seasonal fluctuations as in Korea.

In order to solve the above problems, it is necessary to devise a parabolic fishbone cross-sectional shape so as to have a hydraulically advantageous cross section. It is important to apply the existing rectangular cross-sectional shape to the circular cross section to stabilize the water depth fluctuation according to the flow fluctuation as much as possible. Also, in the past, the fish can not easily enter the fish due to the narrow width of the fish. In order to solve this problem, an inclined auxiliary fish was inclined to the side of the circular channel so that the fish could be easily guided to the fish. And even in the case of small flow rate, it is configured to flow along the circular channel, so that the small stream of fish can be easily formed. By making it wider, it was able to proactively replace the water depth while enhancing the inefficiency as a moving passage due to the existing fixed fishing width. In addition, in general, the construction of the river is carried out for the construction of the beam, and the environment is deteriorated due to the vegetation and fish inhabiting the river, resulting in the damage to the ecosystem. Will be.

In order to achieve the above object, the present invention adopts a block type in the form of assembly at the factory and not in the form of fish that is cast in the field. This will not only shorten the period of occurrence of ecosystem destruction by shortening the construction period due to the installation, but also reduce the pollution of the river caused by concrete harmful substances generated during site casting and contribute to environmental conservation. In addition, in the fishery of the present invention, the cross-sectional shape was improved to round and inclined blocks. This is to construct the cross section of the fish which can cope actively with the fluctuation of the flow, and it is easy to induce the fish because the width of the flow which falls according to the flow of the river is considered.

Hereinafter, the abdominal cross-sectional block according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a double-sided block diagram installation according to the present invention, Figure 2 is a plan view from above the double-word block diagram of the present invention, Figure 3 is a front view of the present invention from the front, Figure 4 is a side view of the present invention This is a side view. 5 to 8 are adobe blocks of each form.

As shown in FIG. 1, the foundation concrete 2 for installing the fish is installed to install the fish 3 and the bow body 1, and the assembling method includes a central groove 7 of the block configured according to each size and shape. ), The fitting groove (8), the protrusions 9 are assembled by combining. The lower body 1 is configured using a block produced according to the size and type of the body, the fish is composed using a total of four blocks, first of all the shape of the circular block (Fig. 5) located in the center Is composed of the fitting groove (8) and the projection (9) and the central groove (7) for assembly. Each block is assembled by the fitting groove (8) and the projection (9), the central groove (7) is used to install the natural stone and the like and to connect the foundation concrete and the block. The connection method is anchored through the center groove (7) when installing the block.

Next to the circular block (Fig. 5), an inclined block (Fig. 6) is provided. The inclined block has a constant inclination (11). The installation method of the inclined block (Fig. 6) is also installed in the same way as the circular block (Fig. 5), and continues to be installed sideways according to the width of the fish. Height difference with the side inclined block according to the installation of the inclined block is the height is adjusted by the base block (Fig. 8). Therefore, the width of the inclined block can be installed without limitation. When the inclination block installation is completed, the finish of the end is finished by installing the finishing block (Fig. 7). With the exception of the finishing blocks (7), the center groove (7) was placed in the center of each block. As described in the circular block (FIG. 5), the function of installing the artificial structure and the function of the groove to connect with the base part are also performed.

Looking at the effect of the double-sectional cross-section block according to the present invention, it is possible to reduce the river water pollution and reduce the ecosystem disturbances due to the river construction by shortening the river construction period by factory production rather than the existing site casting. In addition, the form of the present invention is able to actively cope with the flow rate of the river flow can maintain the fishery function continuously regardless of the flow rate change. According to the assembly method of each block, it is possible to install various kinds of fish, so that it can escape from the uniform river structure. The centrally located grooves allow natural stones (ambers) and other structures to be installed on the island, so they do not easily fall off as if they were simply attached to existing beams.
