Abstract

The invention relates to the technical field of electric poles, and discloses a non-prestressed 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; and a steel reinforcement framework is planted in the ultra-high performance concrete layer. The non-prestressed galvanized steel pipe-ultra-high performance concrete composite electric pole is a composite hollow structure mainly formed bycentrifugal molding of the galvanized steel pipe and the ultra-high-performance concrete, so that the characteristics of good mechanical properties and good corrosion resistance of the galvanized steel pipe and the ultra-high-performance concrete are fully played; the overall performance of the structure is improved; compared with a traditional composite pole structure, the composite pole structure is easy to form, high in bearing capacity, large in rigidity and good in impact resistance, and good in anti-collision and anti-collapse effects; the corrosion resistance is high; and the good corrosion resistance is achieved on atmosphere, water, acid, alkali, salt and various solvents with the general concentration. The non-prestressed galvanized steel pipe-ultra-high performance concrete composite electric pole and the preparation method thereof solve the problems that an existing traditional concrete electric pole is insufficient in bending moment, poor in frost resistance, poor in steelpipe pole corrosion resistance and high in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of electric poles, in particular to a non-prestressed galvanized 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...
