PURPOSE: A pneumatic movable weir for reverse-overturning prevention is provided to prevent overturn of a movable panel by the rotated support panel by rotating a movable panel and a support panel at the same time by an airbag. CONSTITUTION: A pneumatic movable weir for reverse-overturning prevention is composed of a movable panel(30), a support panel(50), and an airbag(60). The movable panel is rotatably connected to a footing concrete by a first fixing unit(20). One end of the support panel is connected to the rear side of the movable panel. The other end of the support panel is connected to the footing concrete to be rotated to the direction opposite to the movable panel by a second fixing unit(40). The airbag is installed between the movable panel and the support panel. The airbag is expanded/contracted by pneumatic pressure to rotate the movable panel and the support panel. |
