Abstract
It creates a flow of water divided into a fast flow month and a slow flow slow stream in a single channel, and provides enough space for the fish to rest, and is easy to pass upstream and downstream from the stream. Provide an Adobe block. Wall parts are formed on both sides of the adobe block, and the partition wall is formed in a zigzag manner in the middle of the channel made by the wall part. This slows down, and the height of the end where the bulkhead is in contact with the wall part and the far end of the wall part is higher than the height of the middle part so that the overflow and rapid flow is formed in the middle of the channel, and the far end and the wall part from the wall part are formed. Slow flow is formed in the flow path formed between.
Description
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.
