    • PROBLEM TO BE SOLVED: To provide a repairing method for a concrete water-passage wall by which a degraded part appearing on a wall surface of a concrete water-passage structure used for hydraulics-related facilities like an industrial water-passage or an agricultural water-passage is removed and fine cracks or the like formed in the surface after the construction can be restrained by improving the strength, as well as to provide the concrete water-passage wall structure.
      SOLUTION: The repairing method for the concrete water-passage wall includes a foundation treatment process for removing the weakened part of the wall including an area of the surrounding normal wall part to expose a sound part inside the normal concrete, and a coating process for coating the sound part with a mortar base material including an organic fiber. The repairing method also includes a successive laying process in which an embedding material is embedded in the mortar base material of a successive joint part of a side face and a floor face of the water-passage wall. The concrete water-passage wall structure 10 has an alkali-resistant glass fiber sheet F and mortar base material layers 12, 13 including a chopped fiber which are formed on a structural cross section perpendicular to the direction of flow of the water passage W by means of the repairing method for the concrete water-passage wall.
