Abstract

The invention relates to the technical field of electric poles, and discloses a prestressed stainless steel tube ultra-high performance concrete composite electric pole and preparation method thereof.The prestressed stainless steel tube ultra-high performance concrete composite electric pole comprises a stainless steel tube and an ultra-high performance concrete layer poured on the inner wall ofthe stainless steel tube, and a prestressed steel reinforcement framework is planted in the ultra-high performance concrete layer. According to the prestressed stainless steel tube ultra-high performance concrete composite electric pole and preparation method thereof, the composite hollow structure is mainly formed by centrifugal forming of the stainless steel tube and ultra-high-performance concrete, the characteristics of good mechanical property and good corrosion resistance of the stainless steel tube and the ultra-high-performance concrete are brought into full play, the overall performance of the structure is improved, and compared with a traditional composite electric pole structure, the composite electric pole structure is easy to form, high in bearing capacity, large in rigidity,good in impact resistance, good in anti-collision and anti-collapse performance, high in corrosion resistance and good in corrosion resistance to atmosphere, water, acid, alkali, salt and various solvents with general concentrations. According to the prestressed stainless steel tube ultra-high performance concrete composite electric pole and preparation method thereof, the problems that the priortraditional concrete electric pole is insufficient in bending moment and poor in frost resistance, and the steel tube pole is poor in corrosion resistance and high in manufacturing cost are solved.

Description

technical field [0001] The invention relates to the technical field of electric poles, more specifically, to a prestressed stainless steel pipe-ultra-high performance concrete composite electric pole and a preparation method thereof. Background technique [0002] The development of my country's transmission line towers has a history of more than 100 years. Among them, since my country produced the first square solid concrete pole in 1924, my country's concrete poles have a history of nearly 80 years. [0003] Most of the electric poles in the prior art are electric poles of reinforced concrete structure, which are cheap in cost, mature in construction and installation technology, and are widely used in transmission lines of various voltage levels in China. However, this structure also has certain limitations: (1) Concrete is a brittle material with low tensile strength, easy to crack, and poor ability to resist natural disasters; (2) The concrete unit density bearing capacit...
