Pier deviation rectifying device and method

The bridge pier deviation rectifying device comprises a pier top supporting part, a deviation rectifying frame and a deviation rectifying force application frame, an anchoring device is used for providing lateral supporting force for the deviation rectifying force application frame, then a drawing device arranged on the same side of the anchoring device is used for providing pulling force, the deviation rectifying frame is used for transmitting the force to one side of a bridge pier, and the deviation rectifying force application frame is used for supporting the deviation rectifying frame. The bridge is supported through the jacks, the contact area between the bridge and the pier top supporting part is reduced, and therefore the bridge can be prevented from being dragged to move when the bridge pier is rectified, and the bridge rectifying force is transmitted through the rectifying force application frame and the rectifying frame; the deviation rectifying force applying frame and the deviation rectifying fram
