A floodgate combined diversion weir for river improvement is provided to prevent a floodgate panel from being closed loosely due to impurities by removing impurities caught in a diversion weir main body and a floodgate panel. A floodgate combined diversion weir for river improvement includes a lifting device(30) connected to a diversion weir main body(10) provided with a water channel(11) having a guide groove and an insertion groove(13) to lift up a floodgate panel(20) to open or close the water channel, a partition plate(40) provided with many drain holes(41) and installed to the inside of the insertion groove in a horizontal direction to divide an inside space of the insertion groove into an insertion(13a) and a water chamber(13b), and a water pump(70) connected to the insertion groove and composed of a cylinder(71) fixed with the diversion weir main body, a piston(72) installed to the inside of the cylinder to form a water supply chamber(71a), a piston rod(73) extended to the upper part of the piston and connected to the floodgate panel, a first water supply pipe(74) extended from the water supply chamber of the cylinder to be extended to the upper reaches of a river and provided with a check valve(74a) to supply water of the upper reaches of a river to the water supply chamber, and a second water supply pipe(75) extended from the water supply chamber to be connected to the water chamber and provided with a check valve(75a) to supply water from the water supply chamber to the water chamber, wherein if a user lifts up the floodgate panel, the piston is ascent by the piston rod connected to the floodgate panel to suction water of the upper reaches of a river and to supply to the water chamber, and if a user descends the floodgate panel to close the water channel, the piston is descent to supply water from the water supply chamber to the water chamber of the insertion through the second water supply pipe and to discharge to the insertion through the drain holes of the partition plate, thereby to push up impurities(1) caught in the insertion groove to be removed continuously. |
