Description

Fish passing block to protect aquatic ecology system

The present invention relates to an adobe block, and more particularly, it can be installed at the bottom of a water channel and a stream of water to store a certain amount of water, and at the same time to allow the fish to rest, and to easily circulate fish along the stream. A fish block that forms a fish that can be traced back, which has a sufficient space for the fish to rest, and is easy to pass upstream and downstream, and is easy to pass through, and is suitable for protecting the aquatic ecosystem. It is about.

Many prior arts are known regarding Adobe blocks. For example, in Korean Patent No. 493392, by arranging the block body for the airway and the drainage channel on the inclined surface formed on the bank or formed naturally on the bank, the inclined plane of the fish that goes upstream is easily moved, Techniques for providing a role are disclosed. According to the technology, fish moving along rivers provide a space to rest in order to accumulate power, thereby eliminating the difficulty of movement on slopes. However, this prior art has a problem that it is difficult to climb upstream because the flow rate of the monthly flow can be secured, but the rest can be secured to rest.

On the other hand, in Korean Patent No. 658432, sidewalls are formed in the longitudinal direction on both sides of the bottom, and partitions are formed in the bottom and the sidewalls, respectively, and partitions are formed at both ends of the bottom and the sidewalls, An Adobe block in which another partition is configured is disclosed. This block has the purpose of slowing down the flow rate in the water channel, making it easy to drop and small fish including fish species with low swimming ability, and to minimize loss of water by minimizing the amount of running water even in a steep slope such as a dam. .

The present prior art has the advantage that the bulkhead can block the waterway to secure the storage space, but because the fish is configured to move only through a specific passage, it has a problem that it is difficult to find the passage in reality.

Korean Patent No. 681338 discloses a technology consisting of a bottom plate having a plurality of vegetation holes, a side wall perforated with a plurality of fastening holes, a fastening bolt for fastening them, and the like, so that the fish can be assembled and constructed in the field. According to the technology, there are advantages in that various types of fish can be quickly and easily assembled and constructed on site. However, the prior art has a disadvantage that the partition wall has a straight shape, so that the effect of mitigating the flow rate is low, and a rapid flow rate cannot be induced.

SUMMARY OF THE INVENTION The present invention aims to solve the problems disclosed in the above-described prior art, and in an Adobe block which exists in a wide variety of forms and manners, the water flow is divided into a fast flow month and a slow flow slow water in one channel. At the same time it creates a flow, it provides enough space for the fish to rest and provides an adobe block that is easy to pass back and upstream from downstream.

According to an embodiment of the present invention for achieving the above object, the adobe block is provided with wall portions on both sides of the adobe block, and a plurality of partitions are formed in a direction that obstructs the flow of water in the middle of the channel formed by the wall portion. It is installed in a zigzag manner, and the end of each of the partition walls far from the wall portion is formed as a refracted end refracted toward the upstream direction, and the end of the partition wall facing the wall portion and the height of the refractive end side are in the middle of the partition wall. Characterized in that it is configured to be higher than the height of the negative.

Preferably, in the above embodiment of the present invention, the vegetation space is formed in the bottom portion surrounded by the flat portion and the refractive portion of the partition wall.

As described above, the present invention is a so-called refractive bulkhead formed by forming a partition wall formed in the middle of an island in a zigzag manner and bending the end portion of the partition wall to be bent in an upstream direction. Since the height is higher than both parts, overflow and rapid flow are formed in the middle of the channel, and the flow path formed between the end and the partition wall far from the wall forms a slow flow, and the shelter of the fish is between the partition and the partition wall. In the part where the space is formed while the partition is formed so as to play a role, the fish can rest, and also, the fish have the advantage of being very quick and easy to go back from the downstream to the upstream.

In addition, since the vegetation space is formed in front of the partition wall, the flow of water can be made slower in this part, so that the fish can go back without any great force from the downstream to the upstream through the flow path in which the slow stream is formed.

BRIEF DESCRIPTION OF THE DRAWINGS The figure which showed typically the state of the beam in which the adobe block which concerns on this invention was installed.
2 is a view schematically showing an adobe block according to an embodiment of the present invention, in which FIG. 2A is a perspective view, FIG. 2B is a plan view, and FIG. 2C is a plan perspective view.

Hereinafter, with reference to the accompanying drawings, it describes the adobe block according to an embodiment of the present invention in detail.

BRIEF DESCRIPTION OF THE DRAWINGS It is a figure which shows typically the beam 1 in which the adobe block 2 which concerns on one Embodiment of this invention is installed, and the installation state of the adobe block. The river is provided with a beam (1) for storing water by stopping the flow of water, in the case of the present embodiment is formed in the middle of the beam (1) to form a passage such as fish, but the position is formed in the technical position of the present invention It is irrelevant to the point.

The adobe block 2 is not particularly limited in its material, but cement or concrete material is preferable. The adobe block 2 has wall portions 21 on both sides thereof, and the wall portions 21 are inclined from the top of the beam toward the bottom of the river downstream of the beam.

As the beam is installed from the upper portion of the beam to the downstream, the fishery can be formed for the fish swimming upstream from the downstream of the stream. In the usual case, when the inclination is formed from the upper part of the beam toward the downstream, the flow of water descending from the beam 1 through the narrow fish block 2 tends to become a torrent. Therefore, it is not easy for the fish or the like to go upstream from the downstream.

In view of this point, in the present invention, the partition wall 22 is provided in a zigzag shape on the wall portions 21 formed on both sides of the adobe block 2. Attempts to slow the flow rate by forming such a barrier in the middle of an adobe block have also been made in the prior art. However, the partition wall in the prior art has a straight line shape, and since the flow velocity is increased by forming a gap between the end of the partition wall and the wall portion, it is easy for the small fish to go back through the gap. Did.

The feature of the partition wall 22 of the present invention is that the refractive ends 22a are formed by first refracting the end portions of the partition walls 22 away from the wall portion 21 toward the upstream direction. At the same time, the structural feature is that the height of the middle portion 22b of the partition wall 22 between the end of the partition wall 22 that is in contact with the wall portion 21 and the refractive end 22a is made low.

According to the adobe block of the present invention formed as described above, the water flow discharged from the beam 1 toward the downstream becomes smooth once by the partition wall. In addition, since the flow of water is circulated by being blocked once by the refraction end 22a and becomes a direction against the flow from the upstream, the flow velocity into the gap formed between the refraction end 22a and the wall portion 21. This will be slower than the non-refractive partition wall.

Therefore, according to the present block 2, the middle portion 22b of the partition 22 in the middle of the waterway, that is, between the end of the partition 22 that is in contact with the wall 21 and the refractive end 22a. Since the height of the () is formed low, the overflow and rapid flow are formed in the intermediate portion 22b, and are formed between the refraction end 22a and the wall portion 21 away from the wall portion. The flow path that results is a slow flow.

Thus, since an alternative slow flow is formed at the bottom of the adobe block 2, it is very easy and quick for fish to go upstream from downstream.

On the other hand, between the partition 22 and the partition wall formed a vegetation space 23 is planted with plants such as plants to serve as a shelter, the fish can rest, and also the water of the water by the plants of these vegetation space 23 As the flow has the effect of slower speed, the fish can be traced back and forth more quickly and easily.

As mentioned above, although the Adobe block of the present invention has been described in detail, this is not intended to limit the present invention, but is merely for illustrative purposes, and it is apparent to those skilled in the art that various changes and modifications can be made within the scope of the present invention.

Such changes and modifications should be construed as being included in the appended claims.
