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.

4 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.

By the way, according to the conventional adobe block, since the river water contained in the air space portion 113 partially flows by the river water passing from the upstream to the air space portion 113, the fish maintains tension in the air space portion 113. It should be, and accordingly there was a problem that the fish can not take a sufficient rest in the atmospheric space 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, since the river water flows over the entire area of the upper surface 112 of the block body 110, there is a problem that the depth of the resting space becomes shallow. This problem is exacerbated in the low season, when the amount of river water decreases.

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 reduce the flow of river water in the rest space, to secure a rest space of a wider fish, to maintain a stable depth of the rest space and to provide an air block having a simple structure.

This is the river block (A) and the combined water block (B) is installed in the river water flows as follows.

The stream water from the upstream flows down through the rest space forming protrusions 21 of the combined block B arranged in a row on both sides.

And this is the fresh water portion (10b) of the adobe block (A) is to contain the river water, and the river water flows along the width direction of the river in the space between the resting space forming protrusions 21 of the combined eodo block (B) installed in the central column . Here, since the river water flows into the freshwater part 10b through the space between the protective wall parts 11, the water depth of the rest space freshwater part 10b can be stably maintained.

As described above, the process of moving the fish upstream through the fish block according to an embodiment of the present invention installed in the river as follows. In FIG. 3, the solid line shows the moving direction of the fish. For convenience of explanation below, the upper protective wall portion 11a and the lower protective wall portion 11b are referred to as 11b.

The fish moves upwards through the resting space forming protrusions 21 of the combined block block B installed in a row on one side.

The fish enters the freshwater part 10b while the fish moves along the protective wall part 11b located below the fish block A while moving upward. At this time, since the protective wall portion 11b at the lower side of the fish block A is formed in a curved shape in which the central region is convex upward, the fish can easily enter the freshwater portion 10b.

Fish entering the fresh water section 10b takes a rest. Here, since the flow of the river water in the freshwater portion 10b is restricted by the protective wall portion 11a on the upper side of the fish block A, the fish can relax and relax.
