To provide a movable weir capable of preventing the occurrence of a water drop, and capable of relieving an upstream side water level variation by a flow rate variation, by automatically adjusting opening of a weir body, while holding an upstream side water level by resistance of a weir body of a submerged weir type, in suppressing generation of bubbles caused by water drop.SOLUTION: A movable weir W interposed in a water passage 1 at least includes: a weir body 2; and a rotary bearing 3 provided in the weir body 2 and capable of rotating. A center of gravity in a movable range of the movable weir W passes a downstream side Y of the water passage 1 with respect to the rotary bearing 3.SELECTED DRAWING: Figure 1
【課題】落水による泡の発生を抑制するにあたり、潜り堰型の堰本体の抵抗によって上流側の水位を保持しつつ、堰本体の開度を自動的に調整することで、落水の発生を防止し且つ流量変動による上流側の水位変動を緩和することが可能な、可動堰の提供を提供する。【解決手段】水路１に介設する可動堰Ｗであって、可動堰Ｗは少なくとも堰本体２と、堰本体２に設けられた回転可能な回転支承３と、を少なくとも含み、可動堰Ｗの可動範囲における重心が回転支承３より水路１の下流側Ｙ通過すること。【選択図】図１
