Zusammenfassung:The invention provides a construction method for repairing and reinforcing a cast-in-place RC floor slab. The surface of the RC floor slab is repaired through the method of carbon fiber cloth plus modified rubber (CFC+MR method for short), the advantages of the high tensile strength of the carbon fiber cloth and the high waterproof ability of the modified rubber are fully exerted, not only is a cracked floor slab repaired and reinforced, but also waterproofness and seepage prevention are conducted, defects of the floor slab are completely overcome and never recur, and integrality of the floor slab and the structure is improved. According to the traditional method, usually, the cracking positions are found first, then a V-shaped groove is poked out and is filled with flexible waterproof materials, and cracks return as the creep growth of concrete; and according to the construction method for repairing and reinforcing the cast-in-place RC floor slab, both waterproofness and leakage stopping and structural reinf
