POOL-TYPE PORTABLE FISH PASSAGE UNIT
To provide a fish passage unit capable of being applied to a fall portion in a river and a water passage and easily maintained and managed at low cost.SOLUTION: A portable fish passage unit includes: floor plates FL disposed in a runup path of fishes; side wall plates ER erected at left and right ends of the floor plates FL; connection plates CNL, CNR fixed to left and right positions of the floor plates FL; a plurality of sloped plates SL1, SL2, SR1, SR2 hinge-connected with the connection plates CNL, CNR and being in contact with the side wall plates ER in a sloped posture; and prevention plates BL1 to BL3 inserted into a gap GV of the sloped plates neighboring in a flow direction to be held in a posture perpendicular to the flow. Water gets over the prevention plates BL1 to BL3 to flow. On the other hand, flowing water pools Pool1 to Pool3 are formed by the floor plates FL, the side wall plates ER and the prevention plates BL1 to BL3.SELECTED DRAWING: Figure 3
【課題】河川や水路内の落差部に適用可能な、低コストかつ維持管理が容易な魚道ユニットを提供する。【解決手段】魚の遡上経路に配置される床板ＦＬと、床板ＦＬの左右端に立設される側壁板ＥＲと、床板ＦＬの左右位置に固定される連結板ＣＮＬ，ＣＮＲと、連結板ＣＮＬ，ＣＮＲにヒンジ結合されて、傾斜姿勢で側壁板ＥＲに当接される複数枚の傾斜板ＳＬ１，ＳＬ２，ＳＲ１，ＳＲ２と、流れ方向に隣接する傾斜板の隙間ＧＶに挿入されることで、流れに直交する姿勢で保持される阻止板ＢＬ１〜ＢＬ３と、を有して構成される。阻止板ＢＬ１〜ＢＬ３を乗り越えて水が流れる一方、床板ＦＬと側壁板ＥＲと阻止板ＢＬ１〜ＢＬ３によって流水プールＰｏｏｌ１〜Ｐｏｏｌ３が形成される。【選択図】図３
