Preventive maintenance treatment method for bridge and tunnel concrete
The invention discloses a preventive maintenance treatment method for bridge and tunnel concrete, which comprises the following steps: S1, cleaning the surface of the bridge and tunnel concrete through a multifunctional maintenance machine for the bridge and tunnel, firstly, carrying out defect detection type treatment on the surface of the concrete through a water spray head and water flow to remove loosened, peeled and aged concrete, and then, carrying out maintenance treatment on the surface of the concrete; and honeycombs, holes and staggered formworks on the surface of the base layer are chiseled away, then a sand blasting head is replaced, and sand blasting rust removal treatment is conducted on the exposed and rusted reinforcing steel bars. The invention has the following beneficial effects: in order to effectively prevent steel bars from rusting again and damage to concrete, the FH-CX rust conversion agent is used for protecting the steel bars, a film layer is firm and compact, the adhesive force is very strong, a steel matrix and a medium are separated and are not eroded, emulsified asphalt thin slurry is used as a concrete protective agent for sealing, and the corrosion resistance of the steel matrix and the medium is improved. The method can be used as a powerful measure for preventive maintenance, the waterproofness of the pavement is greatly improved, and damage such as mud pumping is avoided.
本发明公开了一种桥梁隧道混凝土预防性养护处理方法，包括以下步骤：S1、通过桥隧多功能养护机，对桥隧混凝土表面进行清理，首先通过水喷头，通过水流对混凝土表面进行缺陷探测式处理，去除松动、剥落、老化的混凝土，并将基层表面的蜂窝、孔洞、模板错位进行凿除，然后更换喷砂头，对外露锈蚀的钢筋进行喷砂除锈处理。本发明的有益效果是：本发明为了有效防止钢筋再次生锈，对混凝土造成损伤，通过FH‑CX锈转化剂对钢筋进行保护，膜层牢固致密、附着力极强，使钢铁基体与介质分隔不再受到侵蚀，通过乳化沥青稀浆作为混凝土保护剂进行封层，可以作为预防性养护的有力措施，大大提高路面的防水性，避免出现唧泥等损害。
