Repair structure of existing cement mortar conservation formation of slope

摘要

PPROBLEM TO BE SOLVED: To provide a simple repair structure of an existing cement mortar protective layer of a slope face, which reliably prevents displacement of a repair layer without complicated operation. PSOLUTION: A repair structure of an existing cement mortar protective layer 2 which covers the slope face of a natural ground 1 includes: a bottomed groove 6 for preventing displacement arranged on the surface layer part of the existing cement mortar protective layer 2; and a repair layer 4 of reinforcement resin fiber-containing polymer cement mortar 4' which covers the surface of the existing cement mortar protective layer 2. The groove 6 for preventing displacement is filled with a portion of the reinforcement resin fiber-containing polymer cement mortar, so as to prevent the displacement of the repair layer.
