Abstract

The invention relates to the technical field of electric poles, and discloses a prestressed stainless steel tube-concrete composite electric pole and preparation method thereof. The prestressed stainless steel tube-concrete composite electric pole comprises a stainless steel tube and a concrete layer poured on the inner wall of the stainless steel tube, and a prestressed reinforcement framework isplanted in the concrete layer. According to the prestressed stainless steel tube-concrete composite electric pole and preparation method thereof, the composite hollow structure is mainly formed by centrifugally forming the stainless steel tube and concrete, the characteristics of good mechanical properties and good corrosion resistance of the stainless steel tube and the concrete are fully played, the overall performance of the structure is improved, and compared with a traditional composite pole structure, the composite pole structure is easy to form, high in bearing capacity, high in rigidity, good in impact resistance and capable of preventing collision and collapse; and moreover, the corrosion resistance is relatively strong, and the corrosion resistance to atmosphere, water, acid, alkali, salt and various solvents with general concentrations is relatively good. According to the prestressed stainless steel tube-concrete composite electric pole and preparation method thereof, the problems that the prior traditional 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, in particular to a prestressed stainless steel pipe-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 capacity is low, and the concrete p...
