The invention discloses a micro-crack repairing process for a bridge deck, and belongs to the technical field of bridge repairing. The micro-crack repairing process for the bridge deck is characterized in that a color development reaction of a coloring penetrating fluid is used for helping technicians to judge the micro-crack position of the bridge deck, after the position of a rear micro-crack isdetermined, the to-be-repaired position is chiseled off to form a repairing sinking groove with an inverted conical structure, a glass fiber net and a reinforcing piece are embedded in the forward repairing sinking groove before a concrete slurry is poured to make the mechanical strength of the whole concrete pouring layer easy to improve after the concrete slurry is poured, after the pouring ofthe concrete slurry is completed, a steel plate net is embedded, the steel plate net can form a grid layer on the concrete slurry layer, subsequent coating of a thickened waterproof layer is facilitated, and finally, a coating putty consistent with an original bridge deck in color is sprayed on the thickened waterproof layer to complete micro-crack repairing. Operation is easy and smooth, the repairing mechanical strength is high, and the repairing effect is good.
本发明公开了一种桥梁桥面的微裂纹修补工艺，属于桥梁修补技术领域，一种桥梁桥面的微裂纹修补工艺，通过利用着色渗透液的显色反应来助于技术人员判断桥面的微裂纹位置，在确定后微裂纹位置后，将该待修补位置凿除为倒锥形结构的修补沉槽，在浇筑混凝土浆料前向修补沉槽内嵌设玻纤网以及加强件，从而在混凝土浆料的浇筑后，更易于提高整个混凝土浇筑层的机械强度，完成混凝土浆料的浇筑后，再嵌入钢板网，钢板网在混凝土浆料层上会形成网格层，易于后续加厚防水层的涂覆，最后，在加厚防水层上喷覆与原本桥面颜色一致的涂装腻子，已完成微裂纹修补，操作简单流畅，且修补机械强度大，修补效果好。
