Active and passive dual-protection seawater and sea sand reinforced concrete member and preparation method thereof
The invention provides an active and passive dual-protection seawater and sea sand reinforced concrete member and a preparation method thereof. The seawater and sea sand reinforced concrete member comprises a hollow fiber reinforced prefabricated pipe and a reinforcement cage, wherein the reinforcement cage is located in the fiber reinforced prefabricated pipe, the reinforced concrete member is formed by pouring concrete, the fiber reinforced prefabricated pipe comprises an inner-layer tubular cement-based column body and an outer-layer tubular cement-based column body, conductive fiber gridding cloth is arranged between the inner-layer tubular cement-based column body and the outer-layer tubular cement-based column body, the conductive fiber gridding cloth extends out of the inner-layer tubular cement-based column body and the outer-layer tubular cement-based column body, the the conductive fiber gridding cloth is electrically connected with an anode of an external power supply, a steel bar used for being electrically connected with a negative electrode of an external power source is reserved at the upper end of the reinforced concrete member. By adopting the technical scheme, the external power supply is connected, active and passive protection can be provided for internal steel bars, and the durability and the service life of the seawater and sea sand reinforced concrete structure are greatly improved and prolonged.
本发明提供了一种主被动双重防护的海水海砂钢筋混凝土构件及其制备方法，该海水海砂钢筋混凝土构件包括中空的纤维增强预制管和钢筋笼，所述钢筋笼位于纤维增强预制管内，通过浇筑混凝土形成钢筋混凝土构件；所述纤维增强预制管包括内层管状水泥基柱体和外层管状水泥基柱体，所述内层管状水泥基柱体和外层管状水泥基柱体之间设有导电纤维网格布，所述导电纤维网格布伸出内层管状水泥基柱体和外层管状水泥基柱体外，用于与外接电源的正极电连接；所述钢筋混凝土构件的上端预留有用于与外接电源的负极电连接的钢筋。采用本发明的技术方案，连接外加电源，可以为内部钢筋提供主被动保护，极大地提高了海水海砂钢筋混凝土结构的耐久性和服役寿命。
