Composite high-strength concrete electric pole and preparation method thereof

Abstract

The invention discloses a composite high-strength concrete electric pole and a preparation method thereof. The composite high-strength concrete electric pole comprises a pole body and a base, wherein an assembly hole set is formed in the pole body in the radial direction of the pole body, the base comprises a cylindrical base body, a matching hole set is formed in the base body corresponding to the assembly hole set in a penetrating mode, the pole body is inserted into the base body, steel bars are inserted into all holes of the assembly hole set, the two ends of the steel bars extend into the corresponding matching hole sets, concrete is poured between the base body and the rod body, due to the fact that the structure of the base, wing plates and the like is arranged, the contact face of the rod body and the foundation is increased, the mass of the part, buried in the foundation, of the rod body is increased, the gravity center of the whole structure is lowered, the rod body is not prone to toppling over, the rod body is fixed very firmly and reliably, and the safety coefficient is greatly improved; and the whole rod body is made of raw materials specially researched and developed, the strength of the rod body is high, the anti-cracking performance is good, and the service life of the rod body is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric power materials, and in particular relates to a composite high-strength concrete electric pole and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development and continuous strengthening of power grid construction, the new power transmission lines above 66 kV in Liaoning Power Grid basically do not use concrete poles, but use iron towers with better stability and corrosion resistance. [0003] Telephone poles are one of the important infrastructures for power supply and communication. All kinds of telegraph poles in the early days were wooden poles. Later, due to the development of steel bars and concrete, combined with technical research, the principle of centrifugal force was used to manufacture reinforced concrete telegraph poles instead of large ones.

Problems solved by technology

[0003] Telephone poles are one of the important infrastructures for power supply and communication. All kinds of telegraph poles in the early days were wooden poles. Later, due to the development of steel bars and concrete, combined with technical research, the principle of centrifugal force was used to manufacture reinforced concrete telegraph poles instead of large ones. Compared with wooden poles, cement poles have the advantages of durability, corrosion resistance, temperature difference resistance, high strength, and crack resistance. However, traditional cement poles are only a columnar body. Just bury it in the soil. This type of pole is easy to dump in areas with loose soil or after a long period of rainfall, which poses a greater safety hazard.

[0004] In addition, because many cement poles are located in some areas such as coastal paddy fields, hilly areas, low-lying areas along river basins, and cohesive soil geological conditions, cracks and corrosion will appear to varying degrees after a period of use, resulting in a reduction in the service life of the poles.
