Method for repairing freeze-thaw damage of bridge deck
The invention discloses a method for repairing freeze-thaw damage of a bridge deck, belongs to the technical field of bridge pavement repairing, and solves the technical problems that the existing bridge floor repairing process cannot thoroughly repair and is easy to cause secondary damage and the like. According to the technical scheme, the method for repairing freeze-thaw damage of the bridge deck comprises the following steps that (1) grooving is conducted, specifically, performing grooving downwards from a road surface according to the damage situation till a reinforcing mesh of a bridge deck pavement layer at the damage position is exposed; (2) cleaning residues: cleaning the residues after grooving; (3) mounting elastic rubber strips: transversely and additionally mounting the elastic rubber strips on the exposed reinforcing mesh of the bridge deck pavement layer; and (4) paving the asphalt surface layer: smearing the latex asphalt layer, filling new asphalt above the latex asphalt layer, and pressurizing and tamping to enable the asphalt surface layer of the bridge floor to recover to be flattened. The method has the advantages that the structural design is reasonable, the structure is stable, secondary damage is not easy to occur, and the like.
一种桥面冻融破坏的修复方法，属于桥梁路面修复技术领域，解决现有桥面维修工艺存在的无法彻底修复、易发生二次损坏等技术问题。本发明通过以下技术方案予以实现：一种桥面冻融破坏的修复方法，其中，包括以下步骤：1）开槽：根据破坏情况大小由路面向下进行开槽，至破坏位置处的桥面铺装层的钢筋网片裸露出来；2）清理残渣：将开槽后的残渣清理干净；3）安装弹性橡胶条：在裸露出来的桥面铺装层的钢筋网片上横向加装弹性橡胶条；4）沥青面层铺装：涂抹乳胶沥青层，然后在其上方填补新的沥青并加压夯实，使桥面沥青面层恢复平整。本发明具有结构设计合理、结构稳定、不易发生二次损坏等优点。
