description The invention discloses a construction method for rapid underwater repair of leakage cracks of a concrete faced rockfill dam. The construction method for rapid underwater repair of the leakage cracksof the concrete faced rockfill dam comprises the following steps in sequence: step 1, washing is carried out from top to bottom along the cracks to ensure that the concrete base surface is washed out;step 2, the concrete base surface is washed again; step 3, even painting of a underwater epoxy cement prime coat is carried out along the cracks from top to bottom; step 4, underwater rapid sealing materials are rolled into a cylindrical shape, the materials are bagged and sent underwater; step 5, the cylindrical underwater rapid sealing materials are pressed tightly along the cracks, and it is guaranteed that the middle is thick and the two sides are thin after pressing; step 6, after a flexible surface protection layer is spread underwater along the cracks, a fixed structure is used for fixing the flexible surface p
