Fish facilities with sediment prevention facilities {Fish way having sediment preventable fuction}

The present invention relates to a fishery facility, in particular, to prevent sediment from being deposited at the entrance of the fishery even when the branches, gravel, and soil suddenly flows during the flood, sediment deposition prevention function that can be freely burned and descended even at the low water level It relates to a provided fishery facility.

In general, rivers have a net function of securing water resources such as drinking water, which is installed across rivers to secure agricultural water or drinking water.However, the river acts as an obstacle to restricting small and descent regressive fish along the river. It also has dysfunctional drawbacks that destroy the river ecosystem.

To this end, the Boe provides a free movement environment for regressive fish by creating a moving passage, that is, a fishery, of a regressive fish so that regressive fish can move freely along the stream.

Existing simple cascaded estuaries are deposited upstream of the beams by inflowing tree branches, gravel, and soils into the beams as the flow rate and flow rate of the river increase when the guerrilla intensive weather and floods occur due to frequent weather changes. There was a problem that the upstream fish entrance is blocked by the sediment and the function of the fish is lost. Therefore, in order to maintain the function of the fish, managers have to clean the sediments from time to time, resulting in problems such as waste of cost, short-term ecosystem instability due to the blocking of fish during operation and water pollution.

In addition, the conventional fish has been mainly adopted a stepped structure, which loses the function of the fish due to the lack of the flow rate flowing from the reservoir upstream during the dry season, fish in the feng shui is too fast to flow because the flow rate of the fish is too fast The problem of not being upstream arises.

The present invention has been made in order to solve the above problems, it is possible to prevent the loss of the function of the esophagus due to tree branches, gravel and earth and sand that are introduced during the flood is deposited at the inlet of the upstream esophagus It is an object of the present invention to provide a fishery facility equipped with a sediment deposition prevention function so that regressive fishes do not have a problem of moving upstream or downstream even at low water level by automatically discharging the sediment downstream to the stream.

In addition, it is an object of the present invention to provide a fishery facility equipped with a sediment deposition prevention function so that regressive and migratory fish can freely burn and descend even at the low water level.

Fish facilities equipped with a sediment deposition prevention function according to the present invention is composed of a beam 100 which is basically installed across the river, and the blocking wall 110 is spaced apart a predetermined distance upstream of the beam 100. .

In case of guerrilla intensive weather and flooding due to frequent weather changes, the flow rate and flow rate of the river increases, tree branches, gravel and soil from the upstream flow into the beam 100, and the upstream estuary entrance installed in the beam 100. The function of the fish is lost because it is blocked by sediments and the fish is blocked.

The present invention prevents the sediment is deposited on the esophagus of the beam 100 by blocking the branches, gravel and earth and sand flowing into the barrier wall 110 upstream. As shown in FIG. 3, the sediment flows down from the upstream with the river water, and the sediment collides with the blocking wall 110, and the flow rate rapidly decreases due to the bypass flow, and the sediment is deposited in front of the blocking wall 110. Only the river water flows into the estuary of the beam 100 to prevent sediment from entering and clogging the estuary inlet.

At this time, as shown in Figures 1 and 2, it is preferable to install a plurality of layers in a smaller size than the block wall 110 is composed of a single, which does not significantly interfere with the flow of river water sediment This can be effectively blocked.

That is, after several particles flowing in during the flood hit the barrier wall and are deposited, some of the particles become a channel between the barrier walls in which several layers are stacked, so that some of the particles are distributed to the left or right side of the beam.

In addition, as shown in FIGS. 1 and 2, the blocking wall 110 may be configured in a continuous zigzag curved shape rather than a flat wall shape. This is because the hydraulic pressure of the river water acting on the barrier wall 110 is reduced by forming the barrier wall 110 so as to bend continuously to prevent breakage of the barrier wall 110 due to the hydraulic pressure.

In addition, a part of the sediment collides with the barrier wall 110 and is deposited, and by the vortices generated by the curved barrier wall 110 in a zigzag form, some of the deposit quickly disperses to the left and right of the beam. Considering the general flow rate and flow rate of the river water, the bending angle of the blocking wall 110 is preferably about 100 ~ 120 °.

In addition, the bottom (bottom) of the river is provided with a pipe-shaped barrel 102 connecting the upstream and downstream of the stream across the beam 100, the manhole 103, which is an upstream inlet of the barrel (102) By installing the upstream side of the blocking wall 110, as shown in Figure 4, the sediment that flows with the river water and hits the blocking wall 110 and is deposited in front of the blocking wall 110 through the manhole 103 ( And to discharge through the manhole 103 downstream across the 100.

As described above, the sediment deposited continuously in front of the barrier wall 110 is discharged downstream through the through-hole 102, so that it is not necessary to remove the sediment at regular intervals, thereby making maintenance very easy.

Although not shown in the drawings, it is preferable to further include an opening and closing device (not shown) for opening and closing the barrel 102 by a control device (not shown). In normal and flooding, the reservoir 102 is normally opened to discharge the sediment downstream of the stream, and in the dry season, the reservoir 102 is closed to maintain the quantity of the stream.

1 and 2, a pair of fish protection walls 120 are installed between the barrier wall 110 and the beam 100. The protective wall 120 is installed to be perpendicular to the beam 100 on both sides of the beam 100 at the point where the inclined waterway 150 is installed, but is installed so that the end of the protective wall 120 is in contact with the beam 100.

The fish protection wall 120 installed as described above prevents sediment such as tree branches, gravel, and earth and sand from bypassing the blocking wall 110 from entering the fishery inlet from both sides of the river and before the river water flows into the fishery. The flow rate is lowered while passing through the protective wall 120 to allow the remaining sediment contained in the river water to be deposited to the bottom.

In addition, the opposite end portion of the fish protection wall 120 in contact with the beam 100 forms a deflection portion 121 that is bent at an angle inwardly, thereby reducing the flow rate of the river water when the river water flows inside the fish protection wall 120. Allow it to be deposited on this floor. That is, the river water passing through the narrow inlet due to the refraction portion 121 passes between the wide protective wall 120, the flow rate is reduced to deposit the sediment to the bottom.

Further, by installing a manhole 103 in communication with the passage 102 between the fish protection wall 120, the sediment deposited between the fish protection wall 120 is disposed between the manhole 103 and the passage 102 between the fish protection wall 120. To be discharged downstream. At this time, it is preferable that the manhole 103 installed between the fish protection wall 120 is formed to be large so as to communicate with two or more passages 102. The manhole 103 between the fish protection wall 120 is formed to be large to form the fish protection wall ( 120) by greatly slowing down the flow rate of the river water flowing between the sediment is deposited better, and to discharge the sediment downstream quickly.

In addition, as shown in FIG. 2, a perforated hole 122 is formed in the fish protection wall 120 to increase the amount of river water during flooding or torrential rains, so that the water flows inside the fish protection wall 120 when the flow velocity is increased. The discharge rate is reduced while being discharged to the outside through the hole 122 is configured to effectively deposit the sediment. In addition, the hole 122 also serves to prevent the fish protection wall 120 from collapsing due to a sudden increase in river water.

In addition, as shown in FIG. 2, the refraction portion 121 (part of the river water flowing in) of the pair of protective walls 120 is formed by installing a net 104 having a mesh shape and a metal material connecting the refraction portion 121. It functions to protect the fishery protection wall 120 by dispersing a large impact applied to the fishery protection wall 120 due to branches, gravel, and the like.

It is preferable to provide the guide wall 130 on both sides of the above-described fish protection wall 120.

The guide wall 130 is installed to be spaced apart from the protective wall 120 by a predetermined distance, unlike the protective wall 120 is installed so as not to contact the beam 100, a predetermined distance apart.

The river water introduced between the fish protection wall 120 and the guide wall 130 configured as described above is discharged by being diverted to both sides of the river, and the sediment deposited on both sides of the beam 100 by the river water discharged to both sides of the river. At the same time as it is quickly pushed to the edges, the deposited sediment is floated and circulated while being discharged downstream through the manhole 103 and the barrel 102.

That is, the water flows through the waterway narrowing between the fish protection wall 120 and the guide wall 130 has a function of dispersing the sediment quickly to the left and right of the beam to increase the flow rate.

In addition, the added function is that the sediment is continuously deposited on both edges of the beam 100, the sediment is suspended by the flow of the river water generated by the guide wall 130, while the sediment is circulated through the blocking wall 110 or even Since it is continuously discharged downstream through the manhole 103 inside the protective wall 120, there is no need to periodically clean the maintenance is very easy.

1 and 2, the upstream side of the barrier wall 110 constitutes a frontal barrier wall 140 such that large deposits such as rocks and tree branches flowing along the river bottom during flooding are introduced into the fish entrance. It has a function to block incoming for the first time. The frontal barrier wall 140 is installed at a height lower than the water level of the river so as not to interfere with the small and descent of the regressive fish, and the frontal barrier wall 140 by configuring the notch 141 on the top of the frontal barrier wall 140. Do not allow sediment deposited upstream to continue to be deposited. In the notch 141, it is preferable to form slide grooves on both sides of the notch 141 to insert the partition wall 142. The number of notches 141 of the frontal barrier wall 140 is varied according to the width of the river and the width of the frontal barrier wall.

In addition, a shear key is preferably provided at the base of the beam 100 and the frontal barrier wall 140 of the present invention, and notches 105 are preferably provided at both sides of the beam as shown in FIG. 1.

The inclined waterway 150 is installed on the downstream side of the beam so as to contact the inlet 101 as shown in FIGS. 1 and 5.

In the present invention, through the inclined channel 150 and the inner channel 154 formed in the form of a pipe inside the inclined channel 150, the retreat fish is formed so that small and descent.

On the upper surface of the inclined waterway 150 is installed to be inclined so that the water upstream side of the beam 100 is a natural discharge downstream through the inlet 101, and the side wall 151 of the inclined waterway 150 to the comb wall ( 152 is formed to protrude into the inclined waterway 150, the comb wall 152 is installed at a predetermined interval on the side wall 151 is provided at a predetermined interval to alternate with each other.

It is desirable to be formed to be bent in the form, when the upstream water flows downstream through the inclined waterway 150, the stream water impinges on the comb wall 152 and the water pressure and flow rate is reduced, the regressive fish easily upstream In addition, when the water flowing through the inclined waterway 150 hits the comb wall 152 and is bent and flows, when the returning fish goes upstream of the water flowing through the inclined waterway 150. Rest behind the comb wall 152.

In addition, it is preferable to form a moving groove 153 on the bottom of the inclined waterway 150 to avoid the comb wall 152, and to install artificial plants on the bottom of the moving groove 153.

The moving groove 153 is used when the eels of 4 ~ 8cm in length and 0.2 ~ 0.4cm in circumference go upstream to become a sea urchin. As it goes back upstream, it forms a moving groove 153 having artificial water plants in the inclined waterway 150 as described above, so that the fry such as eel rely on artificial water plants and can easily go upstream. .

In addition, the inner island 154 buried in the form of a pipe inside the inclined waterway 150 is configured so that regressive fish can be burned through the inner island 154 even at the low water level. 6, since the inner fish inlet 155 and the inner fish outlet 156 are installed lower than the low water level, when the low water level, the regressive fish flows back through the downstream inner fish inlet 155 to the upstream inner fish outlet 156. You can do it with me.

The inner fish 154 is configured in a zigzag form continuously as shown in Figures 6 and 7, thereby reducing the water pressure and flow rate of the river water flowing downstream through the inner fish 154 as possible to reduce the internal fish ( It is preferable to configure such that it can be easily burned upstream through 154.

The present invention configured as described above can effectively prevent tree branches, gravel and soil flowing into the fishing facilities of the river to prevent the fishing facilities from losing function due to the sediments, and downstream through the buried passage of sediments The continuous discharge of the furnace is not only very easy to maintain, but also significantly reduced in cost.

In addition, it is a very useful invention that can protect and maintain the river ecosystem by maintaining the function of the fish in the low water level.
