Non-prestressed glass reinforced plastic pipe-ultra-high performance concrete composite electric pole and preparation method thereof

Abstract

The invention relates to the technical field of electric poles, and discloses a non-prestressed glass fiber reinforced plastic pipe-ultra-high performance concrete composite electric pole and a preparation method thereof. The non-prestressed glass fiber reinforced plastic pipe-ultra-high performance concrete composite electric pole comprises a glass fiber reinforced plastic pipe and an ultra-highperformance concrete layer poured on the inner wall of the glass fiber reinforced plastic pipe, the glass fiber reinforced plastic pipe is composed of two half pipes split along the axis, and a steelreinforcement framework is planted in the ultra-high performance concrete layer. A composite hollow structure formed by centrifugal molding of the glass reinforced plastic pipe and the ultra-high-performance concrete is adopted, the advantages of good mechanical property, good corrosion resistance and light weight of the glass reinforced plastic pipe and the ultra-high performance concrete are fully developed, and the overall performance of the structure is improved; compared with a traditional composite electric pole structure, the molding is easy, the bearing capacity is high, the corrosionresistance is high, and the non-prestressed glass fiber reinforced plastic pipe-ultra-high performance concrete composite electric pole has good corrosion resistance to atmosphere, water, acid, alkali, salt and various solvents with general concentrations; and the problems of insufficient bending moment, poor frost resistance, poor corrosion resistance, no insulation and large dead weight of a traditional concrete electric pole, and the problems of large deflection and large pole-climbing shaking of the glass fiber reinforced plastic electric pole are solved.

Description

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