AI Technical Summary
Traditional poles have problems such as corrosion, difficulty in maintenance and risk of stealing in both inland and coastal areas, and are prone to problems such as dirt, flashover, and ice covering in extreme weather.
Corrosion-resistant concrete composite poles are used, which include concrete cylinders, steel cages and corrosion-resistant layers. By adding metal sulfides and polyvinyl alcohol, the metal sulfides automatically repair cracks when they encounter water, and polyvinyl alcohol acts as a hydrophobic material to prevent water vapor from entering.
When cracks appear after long-term use, the self-healing function of metal sulfides and the hydrophobicity of polyvinyl alcohol effectively prevent corrosion and invasion of water vapor, extend the service life of the pole and reduce maintenance costs.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of utility poles, and particularly to a corrosion-resistant concrete composite utility pole and a preparation process thereof. Background Art
[0002] Utility poles are important equipment in power transmission facilities. After power is generated by power generation departments, power is transmitted to users using transmission towers or utility poles. In order to facilitate construction and planning, many utility poles change from high-voltage transmission towers to utility poles after entering a large number of user areas, and utility poles are often erected on both sides of roads. Utility poles erected on both sides of roads are usually made of concrete. Traditional utility poles are generally cement poles, metal poles or wooden utility poles. These utility poles have been widely used in inland areas. Since metal is an excellent conductor and has a high thermal conductivity coefficient, when used as a transmission tower, there are many problems such as pollution flashover, flashover, icing, etc., and anti-corrosion and anti-rust treatments need to be carried out every year, and the risk of theft is also very high. The power grid has to spend a lot of manpower and material resources to maintain it. There are also many difficulties when it is used in coastal areas.

By adding metal sulfide and polyvinyl alcohol, after the utility pole is used for a long time and cracks appear, the metal sulfide automatically repairs the utility pole when it encounters water, and polyvinyl alcohol is a hydrophobic material, so that water vapor cannot enter the interior of the utility pole. When cracks appear in the utility pole, water vapor can only enter the cracks, and then the cracks are repaired.

[0013] Compared with the prior art, for the corrosion-resistant concrete composite material electric pole and its preparation process, by adding metal sulfide and polyvinyl alcohol, after the electric pole is used for a long time and cracks appear on the electric pole, the metal sulfide automatically repairs the electric pole when encountering water. Polyvinyl alcohol is a hydrophobic material, so that water vapor cannot enter the interior of the electric pole. When cracks appear on the electric pole, the water vapor can only enter the crack, and then repair the crack. BRIEF DESCRIPTION OF THE DRAWINGS
