Description

Fish Way Block

The present invention relates to an adobe block, and more particularly, to an adobe block provided on a bottom surface of a river and providing a moving passage of fish that flows from a downstream to an upstream along a stream.

Since it is difficult for fish to move upstream from the downstream of the river because structures such as beams are installed across the river, a technique for installing fish blocks in the river has recently been proposed to assist the movement of fish. It is widely used.

Adobe Block basically moves along the rivers as disclosed in Utility Model Application No. 69496 (designated for rivers), and Utility Model Registration Application No. 390 (designated for Adobe Blocks) in 2001. It has a structure that can provide a resting place for fish.

3 is a perspective view of a conventional adobe block.

The conventional adobe block has a rectangular block body 110 whose transverse length is longer than the longitudinal length, as shown in FIG.

An inclined surface 111 inclined downward from the top is formed on the front surface of the block body 110, and a concave-shaped atmospheric space 113 is formed in the center of the upper surface 112 of the block body 110. have. Waiting space 113 provides a resting space for the fish moving upstream.

In addition, the protrusions 114 are distributed in the transverse direction (the width direction) in the rear end region of the upper surface 112 of the block body 110.

In addition, on both sides of the block body 110, the connecting grooves 115 of semi-circular cross-sectional shapes are formed along the height direction.

The conventional fish block having such a configuration is installed on the inclined surface of the river so that the inclined surface 111 faces upstream. At this time, the adobe block may be installed in an appropriate number along the direction crossing the river and the longitudinal direction. Adjacent adobe blocks are connected to each other by inserting a separate connection member into the connection groove (115).

In the state of the existing adobe block is installed, the river water flows while sequentially passing through the inclined surface 111, the upper surface 112, the upper portion and the protrusion 114 of the air space portion 113, the interior of the air space portion 113 The river will contain river water.

As described above, the process of moving the fish upstream through the conventional fish block installed in the river is as follows.

First, the fish jumps to the upper surface 112 along the inclined surface 111 of the fish block on the lower side, and then swims toward the atmospheric space 113. When the air space portion 113 reaches the fish is slightly submerged into the inside of the air space portion 113. The fish entering the interior of the waiting space 113 takes a break to jump again.

The fish taking a rest in the atmospheric space 113 jumps again and swims toward the inclined surface 111 of the upper block through the space between the protrusions 114.

The fish reaching the inclined surface 111 of the upper block on the upper side flows toward the atmospheric space 113 of the upper block on the upper side in the same manner as described above.

However, according to the conventional fish block, the resting area of the fish is formed in the recessed portion from the upper surface 112 is located at the top of the rest space of the fish in order to move upstream There was a problem in that it is difficult to move between rest spaces because it has to jump and dive in order to enter the waiting space portion 113.

And since the air space portion 113 is formed in a concave structure in the center region, there is a problem that the resting space of the fish is smaller than the size of the fish block.

In addition, when the river water flows in a direction other than the direction connecting the air space portion 113, the protrusion 114, and the inclined surface 111, the fish enters the air space portion 113 or escapes from the air space portion 113. There is a problem in that it is difficult to apply to the river is the flow direction of the river water due to the flow rate is difficult.

In addition, there is a problem in that the structure is complicated because the concave structure called the air space part 113, the convex structure called the protrusion 114, and the inclined structure called the inclined surface 111 must be formed together.

Therefore, an object of the present invention is to move between rest spaces, to secure a rest space for a wider fish, to provide a fish movement path adaptively to the flow direction of river water, and to provide a fish block having a simple structure. It is.

The object is, according to the present invention, in the airway block for providing a moving passage of the fish going upstream from the downstream along the stream, the rectangle is installed on the bottom surface of the stream so that the upper edge toward the upstream of the stream Block body of the upper surface; It is achieved by an adobe block, characterized in that it comprises a resting space forming protrusion protruding from the upper surface of the block body, one each in the adjacent corners of the block body.

In order to improve the resting environment of the fish, it is preferable to further include a plurality of willows formed in the inter-regional area between the rest space forming protrusions to be lower than the rest space forming protrusions.

And in order to be connected to each other block, each of the four corner areas of the block body is formed so as to be parallel to the upper surface cutting surface; Each of the cutting surface may be configured to further include a connecting ring installed along the diagonal direction of the block body.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of an adobe block according to an embodiment of the present invention.

As shown in FIG. 1, the adobe block according to the embodiment of the present invention includes a block body 10 having a rectangular cross section and an upper surface of the block body 10, one each adjacent to the four corners of the block body 10. Rest space forming protrusions 11 protruding from the plurality, and a plurality of support protrusions 12 formed in the area between the resting space forming protrusions 11 and the connecting ring 13 installed one by one in the four corner areas of the block body 10 Has

The cutting edges 10a are formed in the four corner regions of the block body 10 so as to be parallel to the upper surface thereof.

Will protrusion 12 is formed at a lower height than the resting space forming protrusion (11).

The connecting ring 13 is provided along the diagonal direction of the block body 10 on each cutting surface 10a of the block body 10.

The adobe block according to the embodiment of the present invention having such a configuration is installed on the bottom slope of the river so that any one of the resting space forming protrusions 11 faces upstream. At this time, the adobe block may be installed in an appropriate number along the direction and lengthwise direction across the stream in consideration of the width and length of the river slope. And by tying the wires 13 with each other, it is possible to connect adjacent blocks of the adobe.

In the state in which the adobe block is installed according to an embodiment of the present invention, the river water depends on the flow direction.

In other words, when the river water flows down from the upper direction of the block, most of the river flows through the resting space forming protrusions 11a and 11b, and the upper side of the river flows from the direction inclined to the right from the center line of the block. And most of the flow through the rest space forming protrusions (11a, 11b, 11d) located on the right side, and when the river flows from the left side of the center block of the adobe block, the rest space forming protrusions (11a, 11b, located on the upper and left) Most flow through 11c).

As described above, a process of moving fish upstream through the fish block according to the embodiment of the present invention installed in the river is as follows.

First, the fish swims between the spaces between the resting space forming protrusions 11 of the lower block of the fish block and the space between the spaces forming the resting space forming protrusions 11 of the fish block on the upper side. .

The fish that swims into the interspace between the resting space forming protrusions 11 of the combined block at the upper side rest against the willows 12. Here, the protruding portion 12 reduces the flow rate of the stream water flowing through the resting space forming protrusions 11 and causes aeration, in addition to providing a means to lean while the fish rest, thereby reducing the amount of dissolved oxygen in the water. It also increases the resting environment of fish.

The fish taking a rest in the space between the rest space forming protrusions 11 of the adobe block on the upper side passes again between the rest space forming protrusions 11 and between the rest space forming protrusions 11 of the upper block. It swims into space.

In the process of moving the fish, since the resting space forming protrusion 11 and the will protrusion 12 have a similar shape as the gravel of the river, the fish can pass or lean between the spaces without reluctance.

According to the embodiment of the present invention as described above, by forming the resting space forming protrusions 11 from the upper surface of the block body 10 one by one each adjacent to the four corners of the block body 10, the fish between the resting spaces It can easily move, secure a wider rest space of fish and can provide a fish movement path adaptive to the flow direction of the river water. And Adobe Block has a simpler structure.

Therefore, according to the present invention, by forming the resting space forming protrusions each one adjacent to the four corners of the block body protruding from the upper surface of the block body, the fish can easily move between the resting spaces to secure a larger resting space of the fish It is possible to provide a fish migration path adaptively to the flow direction of the river water. And Adobe Block has a simpler structure.
