The present invention relates to a movable weir capable of discharging bottom water, which discharges bottom water downward through a bottom water discharge portion connected to a movable panel, without having any adjustment of the angle of the movable panel, thus securing the contained water level and preventing the decay of river and the destruction of ecosystem. According to the present invention, an oil pressure type movable weir, which adjusts the quantity of water in river by adjusting the angle of a movable panel through oil pressure type cylinders, includes: the movable panel having a bottom water discharge hole formed to pass through the lower end thereof; and a bottom water discharge portion fixedly disposed on the rear surface of the movable panel to open and close the bottom water discharge hole, wherein the bottom water discharge portion includes: a body fixed unitarily to the rear surface of the movable panel and having an inlet formed on one side thereof in such a manner as to communicate with the bottom water discharge hole and an outlet formed on the other side thereof; a watertightness pad disposed along the periphery of the inlet in such a manner as to be located inside the body; guide rails fixedly disposed on both sides of the interior of the body and each having a rack gear disposed on one side thereof; a bottom water discharge floodgate sliding along the guide rails in such a manner as to be brought into close contact with the watertightness pad and having guide rollers and pinion rollers contactedly supported by the guide rails and the rack gears; and driving cylinders fixedly disposed on one side of the body to slide the bottom water discharge floodgate upward and downward. |
