Device and method for measuring deformation of movable formwork

The invention discloses a movable formwork deformation measuring device and method, and the device comprises a plurality of first piers, the tops of the first piers are provided with a movable formwork, the bottom surface of the movable formwork is connected with the top surfaces of the first piers, and one side of each first pier is provided with a second pier. When the top of the movable formwork has no load, a gradienter is used for preliminarily reading a first box staff, a second box staff, a third box staff, a fourth box staff and a fifth box staff in sequence, and initial readings are obtained; after the top of the movable formwork is loaded, a gradienter is used for preliminarily reading the first telemeter rod, the second telemeter rod, the third telemeter rod, the fourth telemeter rod and the fifth telemeter rod in sequence, detection readings are obtained, and the deformation result of the movable formwork is obtained through the relative value of the difference value of the initial readings and th
