Embodiment Construction

[0023] 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, especially with a large width. way of the crack. Using this method, aiming at the cracks with a width greater than 10 mm and less than or equal to 30 mm formed in the wall formed by stacking rocks, a plurality of cracks spanning the cracks and perpendicular to the vertical direction of the wall are arranged at equal intervals along the cracks. Saw the steel bar, seal the crack with mixed mortar, install a plurality of grouting nozzles for pouring the mixed mortar into the crack at equal intervals along the crack from the bottom of the crack, and sequentially The mixed mortar is poured into the crack under low pressure through multiple grouting nozzles, so as to repair the crack. In this method, for cracks with larger widths, in addition to c...

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.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for repairing cracks in walls of ancient buildings. Background technique [0002] Many ancient buildings in China, such as the Potala Palace, not only have a long history, but also occupy an important position in the history of world architecture with their unique style and historical significance, and have extremely high artistic achievements and scientific value. Like all other historical relics, the value of ancient buildings lies in their historical legacy, which cannot be reproduced or rebuilt, and once destroyed, they cannot be recovered. However, during the preservation process of ancient buildings after years of vicissitudes, due to the damage of man-made and natural forces, it is necessary to restore ancient buildings in accordance with the relevant national regulations on cultural relics while maintaining the original appearance of ancient buildings as much as possi...
