In recent years, some dams and weirs that have been designed and constructed have a fishway attached to maintain the ecosystem of fish. In some fishways, a long water channel made of concrete from the upstream side to the downstream side that bypasses a dam or a weir is provided, and a plurality of concrete or steel plate partitions are provided in the water channel at intervals. The water level of this fishway is formed stepwise by the partition walls. Normally, the height of the partition wall is adjusted according to the fluctuation of the upstream water level. In addition, a plurality of partition walls cut off a part of the top of the weir to obtain a water flow that facilitates the backward movement of the fish.

望まれている。[Problem to be Solved by the Invention] However, when constructing a weir, if the site around the weir is too narrow to have a fishway, it is necessary to change the planned site. In addition, if the natural environment is prioritized even in an existing weir without a fishway, the repair space of the weir for providing the fishway is restricted by the installation space. Also, if the terrain is rugged, transport materials for fishways,
Land preparation work is also difficult and costly. For this reason, a fishway device that can be easily assembled without being affected by the installation location of the weir is desired.

As shown in FIG. 1 and FIG. 2, a fishway device 4 is provided on a revetment wall 3 inclined toward the center of the waterway downstream of a fixed weir 2 provided across the waterway 1.
That is, the steel side plate 5 is inclined from the weir apex 2a toward the downstream riverbed, the revetment side edge 5a of the side plate 5 is attached to the revetment wall 3 via the hinge 6, and the other channel side edge 5b of the side plate 5 is provided. Is mounted at a predetermined distance from the revetment wall 3 by the connecting member 7 so as to be higher than one edge 5a, and a V-shaped groove is formed by the revetment wall 3 and the side plate 5. In the groove, a rubber-made inverted triangular partition wall 8 is provided at intervals to form a stepped fishway. In this case, a recess may be formed on the upper side of the partition 8. The connecting member 7 has a hinge 9 at a connecting portion and an intermediate portion so as to be bent.

In this case, the partition 8 is removed and the connecting member 7 is bent. As shown in FIG. 3, when the winder 11 is operated to pull up the side plate 5, the connecting member 7 is located at the hinge 9. As a result, the side plate 5 is brought into a state close to the revetment wall 3.

ものにしている。In the fishway device 4 configured as described above, the overflow water from the fixed weir 2 flows into the ditch to enable the fish to go back. In the event of a flood, the side plate 5 is tilted to the revetment side to reduce the resistance of flowing water, to prevent breakage of the apparatus, and to prevent the downstream area from being affected. If the partition 8 is provided with a connecting mechanism for connecting the revetment wall 3 and the side plate 5, the connecting member 7 can be omitted. Further, since the revetment wall 3 is used as a part of the waterway of the fishway device 4, the number of assembly parts is reduced, the cost is reduced, and the assembling work of the fishway device 4 is simplified.

なる。The fishway device 4 shown in FIGS. 4 and 5 is similarly attached to the fixed weir 2, and the edge 5a of the side plate 5 on the revetment side.
Is fixed by a fixture 12 provided on the revetment wall 3, and a V-shaped groove is formed along the revetment wall 3 so as to be inclined along the revetment wall 3 with the edge 5 a on the revetment side of the side plate 5 as a lower end. The other edge 5b of the side plate 5 is fixed high. And the partition 8 is arrange | positioned and the step-like fishway is formed. At the time of the flood, by removing the lower edge 5a of the side plate 5 from the fixing bracket 12, the side plate 5 is suspended by the connecting member 7 and placed along the revetment wall 3.

ないで済む。The fishway device 4 shown in FIGS. 8 to 10 has one end of the partition wall 8 adhered to the side plate 5, and the other end of the partition wall 8 in contact with the revetment wall 3 is supported by a support member 13 fixed to the revetment wall 3. It is designed to be locked. The partition wall 8 is attached obliquely to the water flow, and is pressed against the support member 13 by the pressure of the water flow. Since the partition 8 is adhered to the side plate 5, the end of the connecting member 7 can be removed from the fixture 12 without removing the partition 8 during a flood. This way,
The partition wall 8 sinks in the water together with the side plate 5, but since the partition wall 8 is attached to the side plate 5 at an angle, the resistance of flowing water is reduced as compared with the case where the partition wall 8 is orthogonally bonded, and the flow of the water flow does not need to be hindered. .

とができる。[Effect of the Invention] Since the present invention is constructed as described above, a fishway can be easily formed by combining a side plate and a partition wall by using a revetment wall on the downstream side of a fixed weir. Since it only transports side plates and bulkheads, it can be installed in existing weirs without fishways in various places. In addition, when installing, there is no need to repair the weir, and the local environment can be maintained.
