Repairing method for hydraulic concrete crack
Provided is a repairing method for hydraulic concrete cracks. A low-pressure grouting repairing method is used, and the method is mainly used for repairing deep and penetrating cracks. Crack grouting comprises cement grouting and chemical grouting, and the cement grouting or the chemical grouting is selected in repairing according to property and aperture of cracks, and construction conditions. For large-volume concrete cracks or cracks which are relatively wide (aperture is larger than 0.3 mm), the cement grouting should be used. For ordinary concrete structural cracks or cracks which are relatively thin (aperture is smaller than 0.3 mm), the chemical grouting can be generally used. For cracks which are severe in leakage and expansion joints, the chemical grouting should be used.
