Integrated gate flap valve structure

The utility model relates to water flow cut-off devices of water conservancy project structures. An integrated gate flap valve structure comprises door frames and a gate plate, the door frames are fixedly installed on a civil engineering structure, the gate plate is installed between the door frames in a matched mode, two pairs of lifting lugs are arranged on the gate plate, two screws are connected to the two pairs of lifting lugs respectively, the other ends of the screws are connected with a hoist, a water passing hole is formed in the plate top of the gate plate, a flap valve is arranged on the outer side of the water passing hole, the top of the flap valve is hinged to the gate plate, and a filter screen is arranged on the inner side of the water passing hole. The integrated gate flap valve structure is high in performance cost ratio, good in economic benefit, simple in gate and flap valve integrated structure, complete in function and saving in cost; meanwhile, civil engineering pipe paving is reduced,
