に配設してなることを特徴とする魚道構造。 On the downstream side of each gate connected in a row from the upstream side to the downstream side, there is a flat plate-shaped part at the overflow top formed in an arc-shaped surface having a radius longer than the head difference with the downstream gate. A fishway structure characterized in that skin plates constituting continuous overflow water guide surfaces are arranged so as to be always oriented toward the upstream side and inclined.
