WATER LEVEL ADJUSTMENT DEVICE AND WATER STORAGE DEVICE
To provide a water level adjustment device that can appropriately manage the water level in a rice field even when the height of the rice field changes.SOLUTION: Provided is a water level adjustment device 10 installed in a catch basin 100 of a rice field, the catch basin having a bottom wall 101 and a pair of side walls 103, 104 erected facing each other from the bottom wall 101. The water level adjustment device comprises: a plate-shaped reference sheathing board 20 that can be installed between the pair of side walls 103 and 104 with the front facing the paddy field side and is provided with a hole penetrating in the front-rear direction; and a movable member 40 having a flow path with an inlet located on the front side and an outlet located on the rear side and assembled to the reference sheathing board so that the flow path passes through the hole, the movable member 40 being assembled to the reference sheathing board 20 so that the position of the lower end of the flow path can be changed. The hole is a long hole extending in the vertical direction and the movable member 40 is slidable along the direction in which the long hole extends.SELECTED DRAWING: Figure 1
【課題】田面の高さが変化した場合においても水田の水位を適切に管理可能な水位調整装置を提供する。【解決手段】底壁１０１と、当該底壁１０１から対向して立設する一対の側壁１０３，１０４と、を有する水田の落口桝１００内に設置される水位調整装置１０である。前面を水田側へ向けて一対の側壁１０３，１０４間に設置可能であり、前後方向に貫通する孔が設けられている板状の基準堰板２０と、流入口が前側に位置し、流出口が後側に位置する流路を有し、その流路が孔を通過するように基準堰板に組付けられる可動部材４０と、を備え、その可動部材４０は、流路の下端の位置を変更可能に、基準堰板２０に組付けられている。孔は上下方向に延びる長孔であり、可動部材４０は、長孔の延びる方向に沿ってスライド可能である。【選択図】図１
