Abstract

The invention relates to the technical field of electric poles, and discloses a non-prestressed stainless steel tube ultra-high performance concrete composite electric pole and preparation method thereof. The non-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 innerwall of the stainless steel tube. The stainless steel tube is composed of two half tubes split along the axis. A steel reinforcement framework is planted in the ultra-high performance concrete layer.The composite hollow structure formed by centrifugal molding of the stainless steel tube and ultra-high performance concrete gives full play to the characteristics of good mechanical properties and good corrosion resistance of the stainless steel tube and the ultra-high performance concrete, improves the overall performance of the structure. Compared with a traditional composite electric pole structure, the composite hollow structure formed by centrifugal molding of the stainless steel tube and the ultra-high performance concrete is simple in molding, reduces circumferential reinforcement, isstrong in bearing capacity, high in rigidity and good in impact resistance, has the advantages of anti-collision and anti-collapse, has higher corrosion resistance, has better corrosion resistance toatmosphere, water, acid, alkali, salt and various solvents with general concentrations, and solves the problems that the prior traditional concrete 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, and more specifically relates to a non-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 ...
