CTRC-steel pipe semi-assembly type RC column facing marine environment and preparation method of CTRC-steel pipe semi-assembly type RC column
The invention discloses a CTRC-steel pipe semi-fabricated RC column facing a marine environment and a preparation method. The CTRC-steel pipe semi-fabricated RC column comprises an inner steel pipe, a TRC shell, a core reinforced concrete layer and an external power supply, the inner steel pipe comprises a plurality of inner-layer steel pipe assemblies which are coaxially stacked in sequence from top to bottom; each inner-layer steel pipe assembly comprises an inner-layer steel pipe section and connecting steel bars used for connecting the longitudinal steel bars; the TRC shell comprises a conductive carbon fiber woven mesh; the cathode of the external power supply is electrically connected with the longitudinal steel bars, and the anode is electrically connected with each circle of carbon fiber woven mesh. By utilizing the excellent conductivity of the carbon fiber woven mesh in the TRC shell, the carbon fiber woven mesh bundle is used as an anode and the internal steel skeleton is used as a cathode by using an impressed current cathode protection method, so that the internal steel skeleton is protected, the overall durability of the structure is effectively improved, and the service life of the structure is prolonged. The anti-corrosion coating is especially suitable for projects such as buildings and bridges in severe environments such as ocean, humid and salinized land and saline-alkali land which are easy to corrode.
本发明公开了一种面向海洋环境的CTRC‑钢管半装配式RC柱及制备方法，包括内钢管、TRC外壳、核心钢筋混凝土层和外加电源；内钢管包括从上至下依次同轴叠设的若干个内层钢管组合件；每个内层钢管组合件均包括内层钢管节段和用于连接纵向钢筋的连系钢筋；TRC外壳包括能导电的碳纤维编织网；外加电源的负极与纵向钢筋通电连接，正极与每圈碳纤维编织网均通电连接。本发明通过利用TRC外壳中碳纤维编织网的优良导电性，使用外加电流阴极保护法将碳纤维编织网束作为阳极，内部钢骨架作为阴极，从而对内部钢骨架进行保护，有效提升结构总体的耐久性能，特别适用于海洋、潮湿、盐渍地和盐碱地等易被腐蚀的恶劣环境下的建筑、桥梁等工程。
