Construction method for adjusting and displacing inclined box girder of high-speed rail

The invention belongs to the technical field of high-speed railway bridge repair, and particularly relates to a high-speed railway inclined box girder adjustment and displacement construction method. A jacking jack is used for centralizing the inclined box girder, and then a three-dimensional jack is used for horizontally moving the box girder; a plurality of jacking jacks are divided into two sets to be arranged on pier caps at the two ends of the box girder, each set of jacking jacks is divided into two parts, one part is installed on the top face of the pier cap on the uplifting side of the box girder, and the other part is installed in a groove of the pier cap; in the box girder righting process, a plurality of jacking jacks alternately jack down; a three-dimensional jack is installed on the top face of a pier cap, the three-dimensional jack is synchronously controlled to transversely move, after the box girder transversely moves to the designed position, a girder body falls to a steel cushion pier, the t
