Concrete structure interface health monitoring and repairing method
The invention discloses a concrete structure interface health monitoring and repairing method, and a damage in-situ monitoring and repairing structure comprises a porous monitoring and repairing film which is laid at a specific concrete structure section. Two external metal copper foils or electrode plates are arranged at the two ends of the section of the concrete structure respectively, the internal porous monitoring and repairing thin film is connected with an external electrical property measuring instrument of the concrete structure to form a sensing monitoring network, and the purpose of monitoring the internal micro-cracks of the concrete is achieved by monitoring the change of electrical properties of the thin film. Concrete repair is achieved through a microorganism mineralization deposition method. The nanocapsules loaded with microorganisms are uniformly distributed in the porous film, or the porous monitoring and repairing film is directly used as a microbial carrier. When the cross section of the concrete structure is deformed or displaced due to external load, concrete cracks are generated at the thin film, the thin film is deformed or damaged, and microorganisms in the thin film are released, so that the function of filling and repairing the cracks of the concrete structure is realized.
本发明公开了一种混凝土结构界面健康监测修复方法，损伤原位监测与修复结构包括：多孔监测及修复薄膜，其被铺放置在特定混凝土结构截面处。在混凝土结构截面两端分别布置两块外接金属铜箔或者电极片，将内部多孔监测及修复薄膜与混凝土结构外部电学性能测量仪器进行连接，形成传感监测网络，通过监测薄膜电学性能的变化达到对混凝土内部微裂缝监测的目的。通过微生物矿化沉积方法来实现混凝土修复。将载有微生物的纳米胶囊均匀分布在多孔薄膜内部，或者直接将多孔监测及修复薄膜作为微生物载体。当混凝土结构截面处因受到外界荷载产生形变或者位移，在薄膜处产生混凝土裂缝，薄膜发生变形或破损，将释放薄膜内的微生物，从而实现混凝土结构裂纹填补修复功能。
