Corrosion-resistant concrete pole
The invention belongs to the technical field of concrete poles, and particularly relates to a corrosion-resistant concrete pole. The corrosion-resistant concrete pole comprises a conical-barrel-shaped reinforcement cage formed by longitudinal steel bars, an annular bar layer wound around the peripheries of the longitudinal steel bars, and a concrete pole body wrapping the outer sides of the longitudinal steel bars and the annular bar layer. The corrosion-resistant concrete pole is characterized in that the annular bar layer is composed of spirally-wound fiber bundles, or is formed by spirally-wound annular steel bars and fiber bundles in a mixed winding mode, or is composed of spirally-wound fiber composite steel bars. According to the corrosion-resistant concrete pole, the corrosion-resistant fiber bundles are wound around the peripheries of the longitudinal steel bars to replace the annular steel bars prone to corrosion, and therefore when the concrete permeability resistance is poor, corrosive media permeate into the surfaces of corrosion-resistant fibers firstly, at the moment, due to the fact that the corrosion resistance of the fibers is good, the fibers cannot be corroded, the mechanical property of the pole body cannot be changed, the problem that the annular bars on the outer layer of the concrete pole are corroded is solved, and then the possibility that the pole body is corroded is reduced or eliminated.
本发明属于混凝土电杆技术领域，尤其是涉及一种耐腐蚀混凝土电杆，包括纵向钢筋形成的锥筒形钢筋笼，在纵向钢筋外围缠绕的环向筋层，在纵向钢筋和环向筋层外侧包裹的混凝土杆体，其特征在于环向筋层由螺旋缠绕的纤维束构成、环向筋层由螺旋缠绕的环向钢筋和纤维束混合缠绕构成或环向筋层由螺旋缠绕的纤维复合钢筋构成。本发明在纵向筋的外围缠绕耐腐蚀的纤维束来代替容易被腐蚀的环向钢筋，这样在混凝土抗渗透性不好时，腐蚀性介质先渗透到耐腐蚀的纤维表面，此时因为纤维耐腐蚀性能较好，不会被腐蚀，杆体的力学性能也不会改变，解决了混凝土电杆外层环向筋被腐蚀的问题，进而降低或消除杆体被腐蚀的可能。
