The present invention relates to a buoyant movable weir structure with a weir of which the part protruding from riverbed when the main body of the weir is moved up by buoyancy in case of ordinary water level blocks the current of water so that a large amount of the water flowing from an upper stream can be stored, or the part not protruding from the riverbed when the main body receiving the water therein is submerged in case of flood water level makes the current of the water toward a lower stream smooth. Provided is a buoyant movable weir structure comprises: a buried box (20); and a movable weir (10) moved up and down by buoyancy, and consisting of a vertical body (16), a lower body (17), and an internal space (14), wherein the vertical body (16) has a front opening into which water flows, and the lower body (17) has a drain from which the water filling the internal space (14) of the movable weir (10) flows. When the movable weir (10) is moved up by the buoyancy in the water flowing through the buried box (20) in case of ordinary water level, the vertical body (16) blocks the current of the water so that the water can be trapped, or when the movable weir (10) is moved down by the water filling the internal space (14) of the movable weir (10) through the front opening (11) in case of flood water level, the water can flows over the vertical body (16) to a lower stream. |
