Precast beam crack repairing construction process
The invention discloses a precast beam crack repairing construction process. The process comprises the steps that for a surface with a precast beam crack smaller than or equal to 0.2 mm, silane impregnating anti-corrosive paint is added twice; and for the surface with a crack larger than 0.2 mm and smaller than or equal to 1 mm, a groove is cut in the length direction of the crack, the crack is repaired and sealed with a high-strength grouting material, and a layer of carbon fiber cloth is attached to the crack. According to the precast beam crack repairing construction process, efficient andhigh-quality repairing of the precast beam crack can be achieved, and problems existing in the prior art can be effectively solved.
本发明公开了一种预制梁裂缝修复施工工艺，其包括对于预制梁裂缝≤0.2mm的表面，采用增加两遍硅烷浸渍防腐涂料；对于0.2mm<裂缝≤1mm的表面，采用沿缝长方向切割开槽并用高强度灌浆料封修补，并粘贴碳纤维布1层。本发明提供的预制梁裂缝修复方案能够对预制梁裂缝进行高效且高质量的修复，可有效克服现有技术所存在的问题。
