Method for repairing crack in historic building wall

Abstract

The invention relates to the field of buildings, and particularly provides a method for repairing a crack in a historic building wall. The historic building wall is formed by piling of rock and is provided with the crack extending in the vertical direction, and the width of the crack is larger than 10 mm and smaller than or equal to 30 mm. The method comprises the steps of arranging a plurality of rebar digging saws which cross the crack and are perpendicular to the vertical direction of the wall along the crack, wherein two or three layers of rock exist between every two adjacent rebar digging saws; blocking the crack with composite mortar; installing a plurality of grouting nozzles used for pouring the composite mortar into the crack in the composite mortar used for blocking the crack along the crack from the bottom of the crack, wherein the distance, in the vertical direction, of every two adjacent grouting nozzles is first distance; conducting low-pressure injection of the composite mortar into the crack through the multiple grouting nozzles in sequence.
