Typhoon prevention method for ascending type movable formwork

The invention relates to a typhoon prevention method for an ascending type movable formwork. The method comprises the steps that longitudinal movement driving mechanisms at a front supporting leg and a middle supporting leg of the movable formwork are tightened and locked; a hanging system is used for tensioning the carrier roller wheels of the front supporting leg and the middle supporting leg; through a first pull rod, the front supporting leg is fixedly connected with a bearing main beam of the movable formwork, and the middle supporting leg is fixedly connected with the bearing main beam; an anti-sliding device is provided, one end of the anti-sliding device is installed on the middle supporting leg in the transverse bridge direction, and the other end of the anti-sliding device is temporarily fixed to a flange plate of a box girder bearing the middle supporting leg; and the front supporting leg is temporarily fixed. The supporting legs of the movable formwork, the bearing main beam, the hanging system an
