ものである。BACKGROUND OF THE INVENTION When a river crossing structure such as a dam or a weir is constructed, flowing water on the upstream and downstream sides is cut off at this boundary, thereby interrupting the exchange of fish. Will be. Then, a water tank for adjustment is provided on the upstream side so as to withstand fluctuations in the water level on the upstream side. Several meters
For the fluctuation of the water level, a sector type fishway is prepared downstream of the embankment, and an elevator type fishway is installed on the high weir. The present invention relates to a fish transport device for a dam installed at a height of a high levee and having a large water level fluctuation on a water storage surface.

Description of the Related Art Conventionally, a fishway has been installed so that fish running up and down in a river run up and down at that time, so that it can be easily performed. The fishway may be installed only during the run-up or descent period, but it is permanently installed along with the weir.

ないものであった。By the way, in a dam with a high levee height, when a stair-type fishway with an appropriate gradient is provided, the waterway of the fishway becomes very long, and the fish is transported in an elevator fishway. Is useful. In a conventional elevator-type fishway, fish can be transported to a bank height of about 40 m, the cage containing the fish is raised, inverted at the highest position, and discharged into the adjusting tank disposed near the highest position. The adjustment tank is connected to the water surface of the reservoir to facilitate the run-up. However, when the water level fluctuation of the water storage surface is large, it is impossible to absorb the fluctuation width with the adjusting tank. In addition, although the sector type fishway can cope with the fluctuation range of the water level up to about 6m, it is not suitable for those with larger fluctuation. In addition, an elevator type fishway proposed by the present applicant (Japanese Patent Application No. Hei 7-242).
No. 458 discloses a structure in which an endless chain is arranged on a vertical frame provided on a dam, a storage box is attached to the chain at intervals, and the fish is transported. This configuration is also unsuitable when the water level of the water storage surface is large because the regulating water tank is provided at the top. In Japanese Patent Application No. Hei 7-145669, an elevator-type fishway is set up to the high point of the dam facing the reservoir on the upstream side of the dam at a high levee height.
From here, a fixed stair-type fishway is provided downstream of the dam, making it easier for fish to descend. However, the step-type fishway was built up to the height of the dam, and it was not easy to go up the fish.
