する袋状堰の倒伏装置。[Scope of Claim for Utility Model Registration] Consisting of a flexible bag-shaped weir installed across a river, and an equipment room having a water inlet that guides the upstream river of the weir into the interior of the weir, the equipment room has an exhaust tank at a riverbed position inside the weir, the inside of the weir body filled with air and the exhaust tank are communicated through an exhaust pipe, and an air outlet opening at a lower end is provided at a predetermined height position in the exhaust tank. A U-shaped pipe is provided that opens outside the exhaust tank at a position that is always in the atmosphere, and that opens inside the exhaust tank from the air discharge pipe in the exhaust tank, and has one end opened at the bottom of the exhaust tank, A siphon is provided which has an outlet that faces downward through a crest of a predetermined height and opens from the bottom at a position approximately half of the weir height to the downstream river side of the weir body, facing upward again. The siphon is communicated with the siphon at a position approximately half of the weir height via an air supply pipe, and furthermore, the siphon has a starting pipe that extends upward from near the crest on the downstream river side and opens at the overflowing water level of the weir. A toppling device for a bag-shaped weir, characterized in that the opening is closed by a cape metal fitting, and a small-diameter drainage port is provided at a position higher than the bottom of the siphon on the lower side of the outlet.
