Abstract

The invention relates to the technical field of electric poles, and discloses a non-prestressed stainless steel tube-concrete composite electric pole and a preparation method thereof. The non-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 reinforcement framework is planted in the concrete layer. According to the non-prestressed stainless steel tube-concrete composite electric pole, composite hollow structure is mainly formed by centrifugally forming the stainlesssteel 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 thestructure is improved, 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 withgeneral concentrations is relatively good; and the problems that an existing traditional concrete electric pole is insufficient in bending moment, poor in frost resistance, poor in steel tube pole corrosion resistance and high in manufacturing cost are solved.

Description

technical field [0001] The invention relates to the technical field of electric poles, and more particularly, to a non-prestressed stainless steel tube-concrete composite electric pole and a preparation method thereof. Background technique [0002] The development of transmission line towers in my country has a history of more than 100 years. Among them, since the first square solid concrete pole was produced in my country in 1924, my country's concrete poles have a history of nearly 80 years. [0003] Most of the poles in the prior art are poles of reinforced concrete structure, which are low in cost and mature in construction and installation technology, and are widely used on transmission lines of various voltage levels in China. However, the 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 concre...
