BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a river facility having a horizontally-

The present invention relates to a river facility, and more particularly, to a water facility installed on a side wall of a river in a river facility installed in a river, such as a snow bridge, to allow the upstream water to flow down, And a transversal fishing line which provides a moving passage for moving the fishing line to upstream and downstream.

Generally, river facilities are installed in rivers in order to secure necessary water for agricultural activities and industrial activities.

In addition, river facilities are installed for flood control and drought stabilization in preparation for flood and drought.

Since such river facilities are installed by crossing rivers, free movement of fish in rivers is blocked, and the habitat environment of river organisms is cut off.

As a result, there is a problem that the river ecosystem disconnected by the river facilities is destroyed.

In order to solve this problem, the government has to set up an island by installing river facilities blocking the crossing of rivers.

As a result, fisheries are installed in river facilities installed in rivers so that fish in rivers can move smoothly upstream and downstream.

However, the existing fishery facilities installed in the river facilities are installed without consideration of the habit of the fish and the environmental factors of the river, and the fishery function is not performed properly, Weak fish could not use the island.

Accordingly, in order to raise the subcontracting rate, to function effectively as a river facility, to lower the gradient, and to efficiently move the river creatures upstream, a variety of fishing facilities are needed.

On the other hand, existing facilities are installed in the longitudinal direction of the river, and in order to lower the gradient, there is a problem that the installation length of the island is increased, the cost is increased, and the landscape of the river is damaged.

In order to solve such a problem, Korean Patent Registration No. 10-0741371 discloses a crosswalk in which a crosswalk is installed in multiple stages across a four-way dam installed upstream of a valley.

However, the above-mentioned prior art is directed to a four-way dam installed upstream of a valley and installed to prevent loss of soil or gravel leaking out to mountainous areas or valleys having a high river-bed gradient, and water is excessively swollen due to deposition of the upstream- When the water is introduced into the fishway, the flow rate provided through the fishway is fast, the fishery function is limited, and there is a problem that the small fishery rate is low because the fishery fish can not easily find the entrance to the fishway.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exemplary view showing a transversal diagram according to a specific embodiment of the present invention; FIG.

As shown in FIG. 1, the transversal fishing line according to a specific embodiment of the present invention includes a stream beam 100 installed as a reinforced concrete across a river so as to drain water upstream of the stream, And a plurality of partition walls 230 installed on the island 200 so as to maintain the water level in the island 200. In this case, .

At this time, the stream beam 100 is installed on the beam structure 10 supporting the stream beam 100 across the stream to desalinate water upstream of the stream.

Here, the stream beam 100 plays a role of controlling the water level of the stream, reducing the flow rate by controlling the gradient of the stream, and increasing the dissolved oxygen amount of the stream by using the fall.

At this time, the river bank 100 is provided with an island 200 in which a constant flow rate is maintained to connect the upstream and downstream of the river disconnected by the river bank 100.

The inlet port 210 is formed on the upstream side of the ARC 200 so that a part of the water that has been desiccated on the upstream side of the stream 100 flows into the ARC 200.

At this time, the EAF 200 is formed in the shape of a water channel having a predetermined gradient from one side of the downstream side wall of the downstream side wall of the river beam 100 to the other side thereof, so that the water flowing through the inlet 210 flows downstream.

Here, it is preferable that the gradient of the ADO 200 is applied with a slope of 1/10 to 1/25.

However, the gradient of the EADO 200 can be applied in various grades according to the shape of the stream or the situation of the stream, so that the fish can be easily removed.

Further, the ID board 200 may be formed in a multi-step shape so as to be formed on one side from the lower side to the other side, and to have a gradient from the bent side to the upper side from the bent side.

Here, a water pool 250 in which water is drained is formed in the curved portion of the island 200.

At this time, it is preferable that the fresh water pool 250 is formed to have a length and a depth sufficient for the small fish to leap the barrier 230 without generating a circulation flow in the fresh water pool 250.

And an outlet 220 through which the water flowing along the EO 200 is discharged is formed on the downstream side of the EO 200.

The partition 200 is provided with a partition 230 for forming a pool to maintain a constant water depth in the pool 200 by using the inflow water introduced into the pool 200.

Hereinafter, with reference to FIG. 2, the structure and the installation method of the partition wall provided in the lateral directional artboard according to the specific embodiment of the present invention will be described in detail.

FIG. 2 is a view illustrating an example of a partition installed on an island in a river facility having a transversal fishing line according to a specific embodiment of the present invention.

At this time, as shown in FIG. 2, the partition 230 is provided with a plurality of the partition walls 230 on the island 200 to reduce the flow rate of the inflow water flowing through the inlet 210.

Here, it is preferable that the partition 230 is installed at a sufficient distance to allow the fishes to take a leap.

The partition wall 230 includes a diverting wall 233 for desorbing influent water to reduce the flow rate of the inflow water flowing into the desalination vessel 200 and a diverging wall 231 for flowing inflow water flowing into the desalination vessel 200, .

The counter flow wall 233 of the partition 230 protrudes upward from the bottom wall 231 to form a pool within the partition 230 installed in the AT 200.

The flow rate reduction wall 235 is formed on the upstream side of the ARC 200 to reduce the flow rate of the inflow water.

At this time, the flow rate reducing wall 235 serves to reduce the flow rate of the inflow water by desorbing the inflow water overflowed from the upstream side partition wall 230.

The water flow wall 231 of the partition 230 is designed to allow the water to flow over and to prevent the damage of the fishes that are taking up by leaping the water flow wall 231 such as salmon, Are formed in a round shape.

Accordingly, the interflow wall 233 maintains a constant water depth of the island 200 forming the pool by dewatering the inflow water, and the water flow wall 231 is formed such that the water desalinated in the partition wall 230 is flowed from upstream to downstream .

 That is, the partition wall 230 maintains a constant water depth in the U-shape 200 while reducing the flow rate of water flowing downstream along the U-shape 200.

A plurality of pores 237 are formed in the lower ends of both sides of the partition 230 to penetrate the wall 230 of the partition 230 so that the lowermost fish can be moved to the upstream side.

At this time, the pore 237 plays a role as a movement passage for the fish which is inhabited on the floor such as crinkle, eel, loach and the like and moves the fish having weak leaping ability, and discharges sediments deposited in the partition wall 230 .

The partition 230 may be pre-fabricated and installed on the island 200.

The construction and the installation method for installing the partition 230 will be described in detail below.

First, as shown in FIG. 2, a plurality of coupling rods 240 protruding from the bottom of the slope 200 of the ADO 200 are installed in the ADO 200.

At this time, the joining rod 240 is reinforced after the rebar 200 is manufactured. And the other end is embedded so as to protrude to the outside of the bottom surface of the earlobe 200 while the other end is embedded in the earlobe 200. [

Here, the coupling rod 240 may be a reinforcing bar or an anchor bolt.

A coupling hole 239 is formed in the partition 230 so that the coupling rod 240 penetrates through the partition 230 to be coupled to the bottom of the sloping surface of the door 200.

Here, the coupling hole 239 is formed to pass through the partition 230 in the upward and downward directions, and the coupling rod 240 is positioned in the coupling hole 239.

In this case, when the coupling rod 240 is formed of a reinforcing bar, the coupling rod 240 is positioned on the coupling hole 239, and concrete is placed on the coupling hole 239 and cured and fixed .

When the coupling rod 240 is formed as an anchor bolt, the coupling rod 240 is installed to protrude from the upper end of the partition wall 230 and pass through the coupling hole 239. Then, And can be fixed on the island 200 by nut coupling.

As described above, when the partition 230 is damaged due to the breakage of the partition 230, it is easy to replace the transversal ellipsoid according to the present invention.

1 and 3, a description will be given in detail of a construction for guiding small-scale fishes to the fishery vessel 200 in the lateral direction fishing boat according to a specific embodiment of the present invention, a principle and a movement route of small- do.

FIG. 1 is an exemplary view showing an example in which a transverse direction fishing line is installed in a river facility according to a specific embodiment of the present invention. FIG. 3 is a view showing an example of a river facility having a transverse direction fishing line according to a specific embodiment of the present invention. Fig. 8 is an example showing the movement path of small-sized fish.

First, as shown in FIGS. 1 and 3, the inlet port 210 on the upper side of the EOF 200 is provided with a U-shaped inlet port 210 for allowing the small- An outlet 211 is formed.

An inlet 221 is formed in the discharge port 220 on the downstream side of the EOF 200 so that a small-sized fish for using the EOF 200 can enter the EOF 200 in the form of a partition wall. do.

At the downstream side of the fishing line 200, an induction wall 260 is provided for guiding the fish to be fed into the inlet 221.

1 and 3, the induction wall 260 includes a first induction wall 261 disposed in the vertical direction of the transverse direction 200 on the downstream side of the AD 200, And a second guide wall (262) provided on the downstream side of the fishing line (200) with an inclined surface with respect to the river channel so that the small-sized fish is directed to the inlet (221).

3, the induction wall 260 blocks the movement path of the small-sized fish moving toward the opposite side of the mouth 221 to guide the small-sized fish toward the mouth 221 .

The guide wall 260 may be formed by rotating the discharge water flowing toward the first induction wall 261 at a higher flow speed and the flow rate of the discharge water flowing toward the second guide wall 262 at a slower speed, So that the small-sized fish can easily make a small-sized image at the entrance 221 by the rotational force.

Hereinafter, for the sake of convenience of description, a flow having a high flow rate is referred to as a main flow and a flow having a flow rate lower than that of the main flow will be described as an auxiliary flow.

As described above, the flow velocity of the discharge water discharged from the discharge port 220 using the guide wall 260 is generally such that the fishes that are scavenged move in the direction of flow, The reason for this is to induce the fish to utilize the auxiliary flow having a relatively slow flow rate among the discharge water discharged from the discharge port 220 by using the characteristics of the fish which are taken up .

In the meantime, referring to Figs. 4 and 5, in the transverse direction according to the present invention, when the river water level rises, the constitution of guiding the fish to the fresh water pool using the overflowing water over the sidewall, Will be described.

FIG. 4 is an exemplary view showing an example in which an upper guide wall is installed in a river facility having a transversal fishing line according to a specific embodiment of the present invention, and FIG. 5 is a cross- Fig. 8 is an example showing an example in which water is floated upstream of a river facility.

4, the upper induction wall 263 guides the small-sized fish toward the freshwater pool 250 when the downstream water level of the river is increased as shown in FIG. 4, As shown in FIG.

The upper guide wall 263 is formed on an upper portion of the second guide wall 262 and is formed as an inclined surface facing the side of the curved portion of the ear canal 200. When the small- (250).

Therefore, when the downstream water level of the river is increased as shown in FIG. 4, the small-sized fishes which are kept at specific water depths according to the wetness of the fish are guided to the curved portion by the upper guide wall 263.

Thereafter, the small-sized fishes flow into the fresh water pool 250 of the inflection part, and pass along the river bed 100 to the upstream side.

On the other hand, as shown in FIG. 5, when the level of the fresh water on the upstream side of the river beam 100 is increased, the river water flows over the river beam 100.

At this time, the overflow water flows into the island 200 and causes a flow of the river water having a sudden flow rate in the direction of the river, so that the island 200 can not perform its function.

Accordingly, in the transverse direction fishing boat according to the embodiment of the present invention, it is possible to prevent the flow of the overflowing water flowing over the riverboat into the island.

Hereinafter, a configuration for blocking the inflow of the overflow in the lateral direction according to a specific embodiment of the present invention will be described in detail with reference to FIG.

FIG. 6 is a view illustrating an embankment installed at an upper end of a river beam in a river installation having a transversal air-intake structure according to a specific embodiment of the present invention.

In the lateral direction according to the embodiment of the present invention, in order to prevent the river water upstream of the river bank 100 from flowing into the river bank 100 through the river bank 100, A canopy portion 270 for blocking the overflowing water is provided.

The beveled portion 270 includes an upright wall 271 protruding upward from the stream beam 100 and a blocking wall 273 extending from the upright wall 271 in the downward direction 200 .

As a result, the overflow water flowing over the river beam 100 falls down to the downstream of the river through the blocking wall 273, thereby preventing the overflow of the overflow water into the island 200.

Therefore, the EAD 200 is prevented from obstructing the flow path in the EAD 200 due to the flow of the overflow.

Meanwhile, the above-described transversal directional arrows according to the present invention can be installed in various arrangements depending on the characteristics of streams and the flow of streams.

Hereinafter, a method of arranging the transversal acoustic tags according to the present invention will be described with reference to FIGS. 7A and 7B.

Figs. 7A and 7B are illustrations showing examples of various installation arrangements in the lateral direction of the present invention. Fig.

As shown in FIGS. 7A and 7B, the transversal fishing line according to the present invention can be arranged in various arrangements when installed in a river.

In general, the flow velocity of a river is relatively faster than that of an edge point (main flow), so that the fish move along a stream flow (a supplementary flow) of a relatively slow flow rate, It is preferable to provide a transversal airway at both ends of the river as shown in FIG.

Since the river shape of the river can be varied depending on various environmental factors, the flow velocity of the river in the transverse direction is measured as shown in FIG. 7B, It is possible.

While the present invention has been described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims. It is obvious that it can be done.

The present invention provides a moving passage for allowing fish inhabited by streams to move upstream and downstream of the river while allowing water stored on the upstream side to flow on the side wall of the river in a river facility installed transversely to the river, The present invention relates to a river facility having transversal fishing lines provided with a transversal fishing line, wherein the fishing line is installed in the river beam in the transverse direction of the river, even if the gradient of the fishing line is lowered, There is an advantage that it can be applied to the required gradient.
