Embodiment Construction

[0024] In view of the lack of technical solutions for repairing cracks in ancient buildings, especially ancient building walls made of rocks in the prior art, the inventor conceived a method for repairing cracks in ancient building walls. Using this method, a mixed mortar is prepared by stirring sand, clay, lime paste, cement and water mixed together in a weight ratio of 3:1:0.5:1:1.5, and the prepared mixed mortar is used to seal cracks, from A plurality of grouting nozzles for pouring the mixed mortar into the cracks are installed at equal intervals along the cracks from the bottom of the cracks, and the low pressure is injected into the cracks sequentially through the plurality of grouting nozzles. The mixed mortar is poured to repair the cracks. In this method, the mixed mortar formed by mixing the above materials in a specific ratio can firmly bond the cracked walls together after being poured into the cracks in the walls of ancient buildings and solidified, increasing th...
