Method for repairing concrete crack in alpine region
The invention discloses an alpine region concrete crack repairing method, and relates to the field of bridges. Comprising the following steps that the thermal expansion coefficient of a to-be-repaired concrete structure and the size of a crack needing to be repaired are obtained; determining the thermal expansion coefficient and fluidity of the repairing material according to the thermal expansion coefficient of the concrete structure to be repaired and the size of the crack to be repaired; the composition of the repairing material is determined according to the thermal expansion coefficient and fluidity of the repairing material, and the repairing material is prepared; repairing a crack, needing to be repaired, of the concrete structure to be repaired by using a repairing material to obtain repaired concrete; and a hydrophobic material is brushed on the repaired concrete surface, curing is conducted, and the repaired concrete structure is obtained. The thermal expansion coefficient of the repairing material can be kept consistent with that of an original concrete structure, the repairing material and an original concrete material are subjected to coordinated deformation in a multi-time freezing and thawing cycle environment, and generation of new cracks is reduced.
本申请公开了一种高寒地区混凝土裂缝修补方法，涉及桥梁领域。包括以下步骤：获取待修补混凝土结构的热膨胀系数及需要修补的裂缝的尺寸；根据待修补混凝土结构的热膨胀系数及需要修补的裂缝的尺寸确定修补材料的热膨胀系数及流动性；根据修补材料的热膨胀系数及流动性确定修补材料的组成，并制备修补材料；使用修补材料对待修补的混凝土结构需要修补的裂缝进行修补，得修补后的混凝土；在修补后的混凝土表面涂刷疏水材料，养护，得修补完成的混凝土结构。可以使得修补材料热膨胀系数与原有混凝土结构保持一致，修补材料与原有混凝土材料在多次冻融循环环境下协调变形，减少新裂缝的产生。
