Culvert construction movable formwork convenient to operate

The utility model discloses a culvert construction movable formwork convenient to operate. The culvert construction movable formwork convenient to operate comprises a foundation table top, a carrying pole beam body, two machining assemblies and two external fixing assemblies. The two sets of machining assemblies are erected on the carrying pole beam body, the machining assemblies are used for rapidly prefabricating the two sides of a culvert, the transverse moving hydraulic cylinder is started, the distance between the outer side formwork and the inner side formwork can be rapidly adjusted, and the distance between the outer side formwork and the inner side formwork can be adjusted according to the actual machining thickness. Then concrete is connected and poured on the outer side formwork and the inner side formwork which are arranged in a high-low staggered mode and a foundation table top to achieve culvert building construction, subsequent automatic, rapid and integrated dismantling can be achieved, much m
