Embodiment 1

[0026] like figure 1 As shown, the corrosion-resistant electric pole, the pole 1 includes a steel frame 2 and a concrete layer 3 wrapping the steel frame, the lower end of the pole 1 is provided with a steel plate end 4, and the steel plate end 4 is connected by a steel wire fixed on pole 1.

[0027] The corrosion-resistant electric pole is prepared according to the following process:

[0028] Take each raw material according to the weight part for later use, wherein: 20 parts of quartz sand, 20 parts of fly ash, 10 parts of gravel, 10 parts of blast furnace slag, 5 parts of desulfurized gypsum, 3 parts of straw powder, 1 part of foaming agent, and 30 parts of water; The slurry obtained after mixing the above raw materials evenly has self-leveling properties. The slurry is poured into a mold pre-installed with a steel skeleton. After 24 hours, the mold is demoulded, and then the end of the steel plate is connected and fixed on the pole through a steel wire.

[0029] The part...

Embodiment 2

[0032] like figure 1 As shown, the corrosion-resistant electric pole, the pole 1 includes a steel frame 2 and a concrete layer 3 wrapping the steel frame, the lower end of the pole 1 is provided with a steel plate end 4, and the steel plate end 4 is connected by a steel wire fixed on pole 1.

[0033] The corrosion-resistant electric pole is prepared according to the following process:

[0034] Take each raw material according to the weight part for later use, including: 30 parts of quartz sand, 30 parts of fly ash, 15 parts of stone, 15 parts of blast furnace slag, 9 parts of desulfurized gypsum, 5 parts of straw powder, 2 parts of foaming agent, and 50 parts of water; The slurry obtained after mixing the above raw materials evenly has self-leveling properties. The slurry is poured into a mold pre-installed with a steel skeleton. After 24 hours, the mold is demoulded, and then the end of the steel plate is connected and fixed on the pole through a steel wire.

[0035] The pa...

Embodiment 3

[0038] Taking common cement concrete electric poles as a control group, the various performances of electric poles of the present invention have been detected, specifically in Table 1:

[0039] Table 1

[0040] performance

[0041] Conclusion: The power pole of the present invention has higher flexural and compressive strength than cement concrete poles commonly used in the market, can be used instead, and saves raw material costs.

Abstract

The invention belongs to the field of electric pole equipment, and discloses a corrosion-resisting electric pole for electric power. The electric pole 1 includes a reinforcement cage 2 and a concrete layer 3 covering the reinforcement cage. The lower end of the electric pole 1 is provided with a steel plate end head 4. The steel plate end head 4 is fixed to the electric pole 1 through steel wire. Application of a cement mortar finished product is avoided, thus saving the cost. Raw materials are reasonable in compatibility. A process is simple. The cost of the electric pole is low, and the electric pole has high strength and good corrosion resistance.

Description

technical field [0001] The invention belongs to the field of electric pole equipment, and relates to a corrosion-resistant electric pole and its application. Background technique [0002] Power poles are an important bridge for electricity, allowing electricity to be transmitted in all directions. Power poles are widely used in projects such as electric power, communication and catenary overhead line lighting pillars and signal machine pillars. The environment is relatively different. In addition to plains and mountainous areas, they are also used in rice fields, reed ponds, swamps, saline-alkali land, and coastal areas. In dry, It has the advantages of high strength and good durability in a non-corrosive environment. The general service life is about 30 years, and the maximum can reach more than 50 years; The concrete layer of the pole is gradually loosened and easily peeled off; or in winter, after the water freezes, the stress generated by the internal volume expansion o...
