The invention relates to the technical field of steel box girder damage detection, in particular to a repair detector for steel box girder damage and a detection method.The repair detector for steel box girder damage comprises a driving vehicle, two repair assemblies and two detection assemblies, and the two detection assemblies are arranged on the two sides of the driving vehicle correspondingly; the repairing assembly comprises a storage box, a pressure pump, a switching valve and sprayers, and the two sprayers are arranged on the two sides of the driving vehicle correspondingly. Each detection assembly comprises a supporting frame, a rotating disc, an ultrasonic detector and a camera, the repairing assemblies and the detection assemblies are driven by the driving vehicle to move, the steel box girder is detected, after the ultrasonic detectors detect damage, the driving vehicle stops, the sprayers conduct repairing through metal repairing agents in the storage boxes, manpower is saved, and the working effi
