External wall grouting and repairing reinforcing method

The invention discloses an external wall grouting and repairing reinforcing method. The external wall grouting and repairing reinforcing method comprises the following steps that grouting holes are drilled in a cavity of an external wall external heat insulation system and drilled to the surface of a base wall, a grouting material is injected into the holes of the grouting holes, taken-out heat insulation structures of the drilled holes are filled back before the grouting material is hardened, flatness is achieved, and obvious stitching height difference does not exist; and flexible crack resistant mortar is brushed and scraped, alkali-resistant glass fiber mesh cloth is embedded internally, and finishing paint is coated. According to the method, the practice of eliminating an original insulation system in a traditional repair method is avoided, and the external wall grouting and reinforcing method is convenient to construct, small in damage area and low in construction manufacturing cost. 本发明公开了种外墙注浆修补加固法，包括
