ある。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing path apparatus using a water level fluctuation device of a contact oxidation levee. [0002] Fish have a habit of going up rivers, and there are weirs at right angles to rivers and waterways. Conventional fishing paths are often provided at the left and right ends of weirs. And it is a hindrance to run-up. In addition, the water flow was strong, and it was not easy to run up the fry and small fish. In addition, conventional fishing paths have little function to improve water quality, activate ecological circulation and produce fish food. Most of the fish that live in rivers grow and end their lives by moving in the lower basin (sea area), middle basin, and upper basin of the river. Generally, fish go upstream from early spring, and in summer, they inoculate abundant nutrients in the upstream and grow.
It becomes an adult fish in autumn and goes down the river. In these river basins, dams and weirs can be created for the purpose of water use, the movement of fish upstream and downstream is significantly restricted, the amount of seafood that consumes underwater nutrients is reduced, and nutrients in water are reduced. It has become clear that the water quality is greatly reduced not only in the fishery environment, but also in the taste and value of sludge and oily river fish as well as in the fishery environment. Therefore, purify the water using the contact oxidation levee, ingest the nutrients in the water into the biofilm, activate the ecological circulation, improve the fishing environment, and make use of the characteristics of fish to facilitate the ascent of the weir. It is assumed that. [0004] Movable weirs are provided on both sides of the upstream and downstream ends of a contact oxide levee having multiple voids provided continuously in the longitudinal direction of flowing water in rivers and waterways. By installing and operating the upper and lower movable weirs alternately, it is possible to facilitate the ascent of fish, and in particular, to reduce the descent of young fish and small fish due to strong currents caused by weiring. In addition, by alternately operating the upper and lower left and right movable weirs, a water level difference is provided between the left and right of the contact oxidation dyke, the contact oxidation dyke is permeated and purified by the water of the river, and the water purification effect is maintained. The direction of transmission of the contact oxide dike is changed alternately from right to left and from left to right to prevent clogging of the contact oxide dike. Furthermore, in order to increase these capabilities and capacities, the above-mentioned devices are sometimes arranged in parallel or in tandem to solve the above-mentioned problems. [Work] Movable weirs are arranged on the left and right sides of the upstream and downstream ends of a contact oxidation levee having multiple voids provided continuously in the longitudinal direction of flowing water, and are located at four locations on the upper, lower, left and right sides. By repeating the operation of the movable weir alternately, it has the effect of a well-known lock type fishing path, and at the same time, a water level difference is provided on the left and right of the contact oxidation dyke, purifying contaminated water in rivers and waterways, Prevent clogging. The water that has passed through the contact oxidation levee is treated in the ecological cycle, such as the biofilm of the contact oxidation levee 1. In this area, insects such as crabs, shrimp, and jaws, and snails are generated. In addition to the abundance of fish and seafood, the water that has passed through the contact oxidation ridge also has a high oil removal rate, the SS drops, the transparency increases, and the algae in the downstream water area, combined with the aeration effect of the contact oxidation ridge. Is generated and photosynthesis is actively performed, resulting in an oxygen-rich water area. Furthermore, it is considered that sludge and the like are decomposed as oxidation ponds, and the fishing environment is improved. Further, since the flow periodically decreases and becomes shallow in the downstream portion, it becomes easy to fly up the fry and small fish. An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a contact oxidation embankment, which is made of a publicly known purification block, concrete block, rock, gravel, gabion, futon basket, or the like. Figure-1
Shows a plan view, and FIG. 2 shows a CC sectional view. Such catalytic oxidation bank was established as 1 to river flow (longitudinal) direction, the upstream end left 2 1 Right 2 2 such catalytic oxidation bank 1,
And, downstream end left 3 1, placed right 3 2. <(A) in the figure> Right 2 of the movable weir upstream of contact oxidation dyke 1
1 closed, left 2 2 open, right 3 1 opening of the movable weir downstream portion, representing the state of the left 3 2 closure. Thus, in FIG. (B), because the river water flowing from upstream is entering the movable dam 2 2 flow to oxidation pond 7 of the right open downstream portion movable weir 3 2 is closed, oxidation ponds 7 water level rises in the catalytic oxidation bank 1 of permeability transmitted while being purified, flows into the oxidation pond 6, the water in which the movable dam 3 1 downstream of the left was cleaned because it becomes Oopun state Runs down naturally. On the other hand, with regard to fish, the fish 10 existing in the downstream water area 9 is in the open state of the movable weir 3 on the downstream left side due to the habitability of fish.
1. Go up the (purified water area), enter the oxidized ground (fish pool) 6, and wait for the state of (b) in the figure. Then <(b) the transition to the state>, the transition to the state (b) in the figure, the upstream portion right movable dam 2 2 closed, the water level of the pound 7 was reduced to about £ 6 it was confirmed, and at the same time opens the downstream portion left of the movable weir 3 1 movable dam 3 2 closed the right, by opening the movable dam 2 1 upstream portion left, the figure (b) condition Become. <(B) in the figure> Right 2 of the movable weir upstream of contact oxidation dyke 1
1 open, left 2 2 closed, the movable dam 3 1 of the right closure of the downstream portion, representing the state of the left 3 2 open. Therefore, the state of (b) in the figure, since the river water flowing from upstream flows to the movable weir 3 1 passes to oxidation pond 7 of the right open but is closed downstream of the movable weir oxide the rising water level of the pond 7, passes through the catalytic oxidation bank 1 left permeable to the right, purified water flows into the oxidation pond 6, the movable dam 3 2 downstream of the left is in Oopun state It flows down naturally. On the other hand, as for fish, the fish 10 existing in the downstream water area 9 has the movable weir 3 which is in the open state on the lower left side due to the habitability of fish.
2 goes back in the natural state (in the clean water area), enters the oxidized ground (fish pool) 6, and waits until the state shown in (a) in the figure is reached. The transition to the state of Figure <transition to the state (a)> (b) a confirmation that the movable dam 2 1 upstream portion right closed, the water level of the pound 6 was reduced to about £ 7 to, at the same time opening the movable weir 3 1 right closes the movable dam 3 2 downstream portion left, by opening the upstream portion movable weir 2 2 left, the state of (b) in FIG.
By repeating the above operations, fish can easily be moved up and the river water can be cleaned. During floods, all weirs are opened. [0007] The operation of the movable weir upstream and downstream has the effect of a well-known lock-type fishing path, and at the same time, the four movable weirs on the upper, lower, left and right sides are alternately operated, so that the contact oxidation embankment is The water level difference is provided on the left and right sides of the river to purify the contaminated water in rivers and waterways, and has the effect of preventing clogging of the contact oxidation embankment. Water that has passed through the contact oxidation levee becomes clean, has a high oil removal effect, increases transparency, and produces algae, photosynthesis is actively performed, and it becomes an oxygen-rich water area, which has the effect of generating and preventing sludge.
Furthermore, since it is treated in an ecological cycle, such as the biofilm of the contact oxidation dyke 1, crab shrimp,
Insects such as goats, snails, etc. are generated, the abundance of fish and shellfish is provided, the fishing environment is improved, and there is an effect of supplying delicious river fish. In the downstream part, the flow periodically decreases and becomes shallow, so that there is an effect that the upstream of the fry or small fish becomes easy.
