Background
Wind energy is increasingly gaining attention as a clean renewable energy source in all countries of the world. China has huge wind energy storage and wide distribution range, and in recent years, wind power generation is rapidly developed and becomes one of the main countries of the world.
The wind power generation equipment mainly comprises a wind power tower body and a wind generating set, wherein most of the wind power tower bodies are formed by connecting a plurality of sections of wind power tower sections with flanges through high-strength bolts.
Wind power plants are typically designed for a life of 20 years. Since the wind farm in Banguchen, Xinjiang, which was first planned, developed and put into operation in 1989, a large number of wind farms that have been put into operation in China have entered or are about to enter the middle and later stages of the design life of the wind farms. With the continuous increase of the operation and maintenance cost of the old unit, the existing wind power plant is renovated and reformed, the occupied excellent wind resource is fully utilized, and the method is an important challenge and development opportunity faced by the existing wind power plant.
In the existing wind power plant renovation and reconstruction implementation process, after a unit is frequently subjected to renovation and reconstruction, the whole or partial segments of the existing wind power tower body cannot meet the strength requirement, and the existing wind power tower body needs to be upgraded or reinforced and reconstructed.

However, if the existing tower body or tower section is reinforced without replacing a new wind power tower body or tower section, the technology is not mature enough at present, and a plurality of problems exist.
For example, the guy cable reinforced tower body method increases the compressive stress of the tower body while reducing the bending moment of the tower body, so that the integral strength of the tower body still cannot meet the requirement.
For another example, in the steel structure welding reinforcing method, the reinforcing structure needs to be welded with the existing tower body at the joint, so that the difficulty and the workload of the field high-altitude welding operation are increased, and meanwhile, the welding can generate larger deformation influence on the thin-wall steel tower body.
For another example, the method for reinforcing the steel-concrete composite structure has the problems of complex concrete construction process, long equivalent-strength period, welding operation and the like.
To sum up, the existing wind power tower body or the reinforcing and transforming of the wind power tower section have great market demands, but the existing technology is not beneficial to actual site construction, and the reinforcing effect is not ideal enough, so that the wind power tower is not widely applied in actual engineering.
