PURPOSE: A movable weir system is provided to reduce costs using an airbag, and to reduce construction time by saving costs and time required for transferring a movable weir. CONSTITUTION: A movable weir system comprises a movable weir(50) and a controller. The movable weir is composed of an airbag(10), a steel panel(I), an air supply pipe, and a joint. The airbag is horizontally installed in a river, and is expanded and shrunken by air when a water level is ascended and descended. The steel panel opens river water by the expansion and contraction of the airbag. The air supply pipe supplies air to the airbag. The joint fixes the steel panel to the bottom surface of a river. The controller controls an air supply unit using a water level sensor. |
