Description

Fish-way in Liver Having Triangle Stone Wall}

The present invention relates to fish ponds, and more particularly, to a variety of water depths and flow rates are formed and suitable for the movement of a variety of fish species and eco-friendly fish ponds.

In general, a river (or dam, hereinafter referred to as “bo”) facility is installed in the river to block the natural discharge of water by confining water to a certain height across the river to secure drinking water and agricultural water. do.

These structures are very useful in terms of protecting water resources that can be lost by flowing downstream, but they limit the free movement of fish (including crustaceans and other aquatic organisms) in rivers, threatening their survival and ecosystems. It is accompanied by side effects that destroy it.

Therefore, the various beams are made to prevent the ecological damage caused by the construction of the fish by creating a fishery that does not interfere with the fish's soha (fish go up the river for spawning).

However, existing fishes are generally artificial fishes, which are mainly concrete, and have a problem of incongruity in terms of harmony with the river view, and most of them are designed for specific fish species that maintain a constant flow rate by maintaining a large step. In the case of intake basin for the purpose of freshwater, there is a problem that it is difficult to secure the desired freshwater quantity due to the large loss of oil through the fish.

There are many types of fish applied to beams, for example, cascading fish, wall fish, ice harbor fish, vertical slot fish, and artificial fish food.

Cascade fishery, the pool is cascade continuous fish (pool-type), there is an advantage that the construction is convenient and the construction cost is low, but there is a disadvantage that the sulfur of the fish is bad and the circulation flow occurs in the pool.

Conduit type fish is a fish (waterway type) in which a continuous flow path is formed without a drop, there is an advantage that the sulfur of the fish is good, but there is a problem that the flow rate is fast, uneven and the amount of sewage water is large.

The ice harbor fish is a kind of fish pool in which the grass is cascaded, and the sulfur of the fish is good, but the construction is difficult due to the complicated structure.

Vertical slot type fish is a type of pool type fish which cascades continuously and has the advantage that it can be installed even in a narrow place, but there is a problem in that the water loss is large due to the difficulty in construction due to the complicated structure and the amount of flowing water.

In addition, the artificial island type fish is a channel-type fish that forms a continuous flow path without dropping, but all fish species have the advantage of being movable, but it takes a large area and difficult to secure the site and excessive construction cost.

Fourth, natural materials such as natural stones are mainly used in place of existing concrete, thereby providing an eco-friendly fishery having a natural landscape in terms of restoring the nature of the river.

Hereinafter, with reference to the accompanying drawings will be described in more detail the river esophagus provided with a triangular stone wall according to the present invention. The following embodiments merely illustrate the river channel according to the present invention, but are not intended to limit the scope of the present invention.

As shown, a river channel 1 having a triangular stone wall according to the present invention basically includes a water channel 10, a stone wall 20, and a water depth portion 30.

The water channel 10 is installed in a position where it is necessary to form an esophagus in a beam construction such as a river, and is a conventional water channel structure for making a water flow flowing from upstream to downstream for the flow of fish, and the size and habitat of the corresponding river The shape and size can be determined in various ways depending on the characteristics of the.

For example, the channel 10 may be formed of a concrete structure having a thickness of about 300 mm, but may be formed in an open cross-sectional Diangular shape having a width (W) of about 3,000 mm and a height (T) of about 1,000 mm. . At this time, the outer wall of the water channel 10 may be finished by attaching two layers of stones 14 in consideration of aesthetics and the like.

The inclination of the channel 10 is not particularly limited as long as it can act as a fish, but the water flowing therein is formed to have a longitudinal inclination (upstream-downstream inclination) of 1/20 or less so as to exhibit a gentle flow rate. desirable.

In addition, in the construction of the waterway 10, by using a natural stone such as gravel in addition to concrete, the fish can be more natural-friendly (1) of the present invention.

Specific structure and construction method of the channel 10 can be applied to the channel construction technology widely applied in the related art, the channel 10 itself is not directly related to the features of the present invention, the details Description is omitted.

According to the feature of the fishery 1 according to the present invention, the waterway 10 is provided with stone walls 20 at regular intervals.

Each stone wall 20 has a filling zone 21 and a filling stone 22.

The filling zone 21 is a zone formed so that the filling stones 22 filled therein are not lost to the water stream, and the post 21a, the upstream rope 21b, the downstream rope 21c and the vertical rope 21d are formed. Equipped.

The post 21a is a pillar member for upright and downstream ropes 21b and 21c, which is installed upright at the center of the waterway bottom 11 (not necessarily the center, but preferably the center).

The post 21a is not particularly limited as long as it is a member that is resistant to corrosion in use in water, and has a strength that is sufficient to prevent the filling stones 22 from being swept away from the water stream. Stainless steel pipes that are not corroded can be used.

Such a post 21a is a PVC tube slightly larger in diameter than the post 21a pre-buried in the bottom concrete 11 and the bottom concrete 13 when the bottom concrete is poured on the channel bottom 11 and the channel bottom 11. 21e) and can be fixed.

In the illustrated example, the post 21a is about 50MM in diameter and about 1,000MM in length, and the PVC pipe 21e is about 65MM in diameter and about 500MM in length.

The upstream rope 21b is a rope connected between the post 21a and both sidewalls 12 of the channel 10 so as to traverse the channel 10 in the transverse direction (horizontal direction), and is filled in the filling area 21. The stones 22 are prevented from escaping in the upstream direction of the channel 10.

Connecting the upstream rope 21b transversely to the waterway 10 does not only mean crossing the waterway 10 exactly horizontally, but as shown in FIG. 3, to the post 21a. As the binding position on the side wall 12 is slightly downstream from the binding position, the V-shaped binding which is formed in a wide open U-shape whose angle about the post 21a is close to 180 degrees and is not excluded.

The downstream rope 21c is a rope connecting the waterway 10 diagonally across the post 21a and the side wall 12 located downstream thereof, and the filling stones 22 filled in the filling area 21 The departure is prevented in the downstream direction of the channel 10.

The downward diagonal angle of the downstream rope 21c is not particularly limited, but is preferably about 45 degrees so that the angle formed by the two downstream ropes 21c connected to the same post 21a is about 90 degrees. Do.

The vertical rope 21d fills the gap 22 between the upstream and downstream ropes 21b and 21c and the channel bottom 11 by vertically connecting the upstream and downstream ropes 21b and 21c with the channel bottom 11. This prevents it from escaping.

Therefore, the vertical ropes 21d are applied at appropriate intervals so that the filler stones 22 do not escape in consideration of the size of the filler stones 22 to be applied.

The ropes 21b, 21c and 21d are not particularly limited as long as they are resistant to corrosion in use in water and have a strength sufficient to prevent the filling stones 22 from being swept away from the water stream. For example, stainless steel ropes (wires) that do not easily corrode in water can be used (eg diameters 10-20 mm).

Binding the ropes 21b, 21c, 21d to the posts 21a, the side walls 12, and the channel bottom 11 may use conventional binding means that are well known, for example, the rope fixing anchor 23 may be used. Can be used.

The upstream and downstream ropes 21b and 21c may be arranged in multiple rows with a vertical gap such that the filling stones 22 do not escape therebetween. 1 is an example in which two ropes are tied up and down in parallel so that the distance between the upstream and downstream ropes 21b and 21c on the bottom concrete 13 is about 200-250MM, and FIG. This is an example of binding three ropes in parallel. The interval between the upper and lower ropes of the upstream and downstream ropes 21b and 21c may be appropriately selected depending on the size of the channel 10 and the size and load of the filling stone 22 to be applied.

By the post 21a and the ropes 21b, 21c, and 21d, the channel 10 is formed with two triangular-shaped filling zones 21 which are symmetrically opposed to and positioned about the post 21a.

The filling zone 21 is filled with the filling stones 22 of natural stones such as round amber stones that can be collected from nature.

The size of the filling stone 22 is appropriately selected according to the size of the channel 10, the characteristics of the inhabitant fish, the spacing density of the ropes 21b, 21c, 21d, and the like. In this case, for example, amber stones of various sizes ranging from 700 mm to 200 mm in average diameter can be stacked and charged without loss.

As a specific example, the filling stones 22 may be stacked in three levels, and the bottom may be stacked in a size of 200MM-400MM and the size of 400MM-700MM may be stacked at the top. Between the amber stones constituting the filling stone 22 is preferably filled to have an appropriate gap to provide a refuge for the fish.

In addition, the filling stones 22 can be charged such that the height of the upper end thereof becomes lower (having a downward slope toward the center of the channel) toward the center of the channel 10, that is, the post 21a. The water flowing through the waterway 10 receives less resistance toward the center of the waterway 10 so that its flow rate is increased so that various fish species can be moved by providing various flow rates and depths.

The water depth part 30 is a space in which water that fish can swim, is a space surrounded by adjacent stone walls 20.

As described above, the triangular stone wall 20 is repeatedly installed in the channel 10 at regular intervals, and thus a space in which the stone wall does not exist is formed between the adjacent stone wall 20 and the stone wall 20. This becomes the depth part 30.

As the stone walls 20 are two triangles that are symmetrically located, the depth portion 30 is approximately triangular (when the upper and lower stone walls are spoken immediately adjacent to each other) or a pentagon (when the upper and lower stone walls are installed at a predetermined distance apart). The bottom portion of the post 21a has almost no filling stones 22, so the depth of the deepest portion becomes the deepest part.

In the illustrated embodiment, the distance G1 of the adjacent upper and lower posts 21a is approximately 2,000 mm, and the stone wall is positioned downstream from the end of the side wall 12 of the downstream rope 21c of the stone wall 20 located upstream. The distance G2 between the end of the side wall 12 of the upstream rope 21b of 20 is approximately 500 mm, and the end of the side wall 12 of the upstream rope 21b and the downstream rope 21c of the same stone wall 20 are approximately 500 mm. The distance G3 between the end portions of the side walls 12 is approximately 1,500 mm.

The distance between adjacent stone walls 20 (distance between adjacent posts) is preferably about 2/3 to 1.5 times the width W of the channel, and may also equalize the distance between all the stone walls 20. Water flow by increasing the spacing between the stone walls relatively slightly upstream, or at least slightly wider between the stone walls at the upstream, so that the uppermost depth portion 30 is wider than the other depths. You can make the fish that dates back to a place to rest.

The part where the stone wall 20 is not installed in the waterway bottom 11 may be finished so that the waterway bottom 11 is exposed as it is without applying a separate finishing material or by attaching artificial stone to the poured concrete floor 13. However, it can be finished by attaching the bottom stone 40 which is preferably natural stone.

The bottom stone 40 to be applied is not particularly limited as long as the waterway bottom 11 is landscaped with an eco-friendly natural stone and does not interfere with the flow of water and the flow of fish, for example, a round or about 100MM to 400MM diameter or Round flat amber stones can be appropriately laid on the bottom concrete 13 to form.

As described above, the river esophagus 1 having the triangular stone wall according to the present invention has various water depths and flow rates formed by the action of the stone wall 20 and the water depth portion 30 regularly installed in the waterways, It is suitable for movement and is provided with voids and bent parts by natural stones such as amber stones and gravel included in the stone wall 20, and is also suitable for the movement of crab and fishfish, and various flows by using natural stones of various sizes in the stone wall 20. Overflow speeds are formed to provide a variety of ecologically accessible fisheries, ranging from fish and catfish, such as catfish and carp, to strong fish, such as sweetfish and yellowfish. In addition, natural materials such as natural stone are mainly used as the stone wall 20 and the bottom stone 40, thereby becoming an environmentally friendly fishery having a natural landscape in terms of restoring the nature of the river.
