description The invention relates to a double-phase corrugated stainless steel damaged tunnel rapid reinforcing device and method.The device comprises steel corbels, corrugated steel, fixing anchor bolts and filling mortar, the corrugated steel is spliced into a corrugated steel ring and connected with a ballast bed through the steel corbels, and gaps between the corrugated steel ring and a lining structure are densely filled with the mortar; and a common stress structure is formed with the original tunnel structure, so that the effect of permanently reinforcing the damaged tunnel is achieved. The corrugated steel is mounted in a one-way mode, and a special closing-in adjusting device is adopted for distance adjustment during final closing-in; the initial setting time of grouting mortar is 30 min, the maximum aggregate particle size is smaller than 0.2 mm, a top grouting mode is adopted, two holes are formed in the wave crest position, one hole serves as a grouting hole, the other hole serves as an exhaust hole, and grou
