Method and tool for repairing microcracks
The invention discloses a method and tool for repairing microcracks, and belongs to the technical field of crack repairing. The method comprises the following steps that concrete on the surface layers of the cracks are ground along the trends of the cracks, and floating dust in the cracks are removed by using the pressure of compressed air; A and B for crack repairing are blended; the A and the B are injected into different material cavities in a concrete crack repairing tool according to a certain proportion; the A and B are injected into a static mixing pipe of a repairing tool, and mixing is carried out to form a filling material; filling materials are injected into the cracks through a needle at the top end of the static mixing pipe until the whole cracks are filled; and after filling is completed, a layer of fine powder is evenly scattered on the filling materials, after the filling materials are solidified, the residual filling material and the fine powder on the surface layer of the protruding cracks are cleaned, and a sealing layer is poured on the surface of the concrete. According to the method, the filling materials can be injected into the cracks smaller than 0.2 mm through the needle head in the repairing tool, and the effects of bonding reinforcement and permeation reinforcement on the microcracks are achieved.
本发明公开了一种微细裂缝的修补方法以及修补工具，属于裂缝修补技术领域，包括将沿裂缝走向的裂缝表层混凝土打磨，并利用压缩空气的压力清除裂缝内的浮尘；调配裂缝修补的A和B；将A和B按照一定的比例注入到混凝土裂缝修补工具中不同的料腔内；将A和B注入到修补工具的静态混合管内，混合形成填充材料；随后填充材料通过静态混合管顶端的针头注入到裂缝内，直至填满整个裂缝；填充完后，在填充材料上均匀撒一层细粉料，待填充材料固化后，清理凸出裂缝表层残留的填充材料及所述细粉料，并在混凝土表面上浇注一层封闭层。本发明利用修补工具中的针头，将填充材料能注入到小于0.2mm的裂缝，对微细裂缝起到粘结加固、渗透补强作用。
