Embodiment

[0031] see figure 1 , is an anti-corrosion construction method for wind power foundation anchor bolts provided by an embodiment of the present invention. The wind power foundation anchor bolt anticorrosion construction method described in the present invention provides a non-metallic coating, which can effectively prevent and delay the surface corrosion of the anchor bolt, and improve the durability and service life of the wind power foundation anchor bolt. The method provided is a simple Reasonable, cost-effective anti-corrosion method. The anchor bolts constructed by this method have the characteristics of super weather resistance and super corrosion resistance. Using a variety of coatings, multi-functional anti-corrosion, can resist the corrosion of various harsh media, the salt spray resistance of the system is 5000-10000 hours, and the outdoor service life is more than 20 years.

[0032] like figure 1 As shown, the anchor bolt includes a middle section and threaded sec...

Abstract

The invention discloses a wind power foundation anchor bolt anticorrosion construction method which comprises steps of spraying pretreatment and anticorrosion spraying. The wind power foundation anchor bolt anticorrosion construction method disclosed by the invention is simple and reasonable; on the basis of overall consideration of factors such as durability, maintenance economy and environment-friendliness of various anticorrosion methods, the invention provides a fluorocarbon coating construction method, that is, a wind power foundation anchor bolt long-lasting treatment method. An anchor bolt manufactured with the method has characteristics of super weather resistance and super corrosion resistance. As multiple coatings are used, the purpose of multifunctional anticorrosion can be achieved, corrosion caused by various disgusting media can be prevented, the salt mist resistance of a system can be 5000-10000 hours, and the outdoor service life can be longer than 20 years.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion construction, in particular to an anti-corrosion construction method for wind power foundation anchor bolts. Background technique [0002] In the wind power industry, anchor bolts are special bolts that connect the steel tower of the wind turbine and the foundation concrete. The anchor bolts embedded in the foundation concrete go deep into the lower surface of the foundation cap, and the anchor bolts pass through the outer anchor bolt casing. Separated from concrete. [0003] Because the site selection of wind farms is different from that of traditional power plants, the meteorological conditions, climate conditions, and geographical conditions are relatively harsh. The general ambient temperature range is -40℃~50℃, and the working environment temperature range is -40℃~100℃. ℃, relative humidity ≤ 95%, wind turbines operate in outdoor climate conditions with high air humidity, high salinit...
