Prestressed galvanized steel pipe-ultra-high performance concrete composite electric pole and preparation method thereof
The invention relates to the technical field of electric poles, and discloses a prestress galvanized steel pipe-ultra-high performance concrete composite electric pole and a preparation method thereof. The electric pole comprises a galvanized steel pipe and an ultra-high performance concrete layer poured on the inner wall of the galvanized steel pipe; the galvanized steel pipe is composed of two half tubes cut along an axis; and a prestressed reinforcement framework is planted in the ultra-high performance concrete layer. The composite hollow structure formed by centrifugal molding of the galvanized steel pipe and the ultra-high performance concrete gives full play to the characteristics of good mechanical properties and good corrosion resistance of the galvanized steel pipe and the ultra-high performance concrete, improves the overall performance of the structure, has the advantages of simple molding, strong bearing capacity, large rigidity, good impact resistance and good anti-collision and anti-collapse performance compared with a traditional composite pole structure, and has good corrosion resistance and good corrosion resistance to atmosphere, water, acid, alkali, salt and various solvents with general concentrations. The prestress galvanized steel pipe-ultra-high performance concrete composite electric pole and the preparation method thereof solve the problems of insufficient bending moment, poor frost resistance, poor corrosion resistance and high manufacturing cost of a traditional concrete pole.
本发明涉及电杆技术领域，公开一种预应力镀锌钢管‑超高性能混凝土复合电杆及其制备方法，包括镀锌钢管和浇筑于镀锌钢管内壁的超高性能混凝土层，所述镀锌钢管由沿轴心剖开的两个半管组成，所述超高性能混凝土层中植有预应力钢筋骨架。镀锌钢管和超高性能混凝土经离心成型的复合空心结构，充分发挥镀锌钢管和超高性能混凝土力学性能好、耐腐蚀性能好的特点，提高结构的整体性能，较传统的复合电杆结构成型简单，承载能力强，刚度大，抗冲击性、防撞倒塌性能好，而且具有较强的耐腐蚀性能，对大气、水和一般浓度的酸、碱、盐以及多种溶剂都有较好的耐腐蚀能力，解决了现有传统混凝土电杆弯矩不够、抗冻性能差、钢管杆耐腐蚀性能差、造价高的问题。
