Problems solved by technology

At present, the most commonly used form of offshore wind power foundation is the large-diameter single-pile foundation. For offshore wind farms with thick soft soil layers under the mud surface, the risk of the rotation angle of the single pile at the mud surface under extreme load conditions may exceed the standard limit value , at the same time, its horizontal bearing capacity is difficult to meet the requirements, which brings hidden dangers to the safe operation of wind turbines

Abstract

The invention relates to a construction method of a fan foundation, the fan foundation and a wind generating set, the construction method comprises a reinforcing assembly providing step, a pretreatment step, a penetration step and a grouting step, and the provided reinforcing assembly comprises an adapter and more than two reinforcing cylinders. In the pretreatment step, a reinforcing assembly can be matched with a main supporting piece through an adapting piece, when the penetration step is executed, the reinforcing assembly can penetrate into a preset depth in a mud layer in the height direction of the main supporting piece through the adapting piece and is fixedly connected with the main supporting piece, and through the correspondingly arranged grouting step, a reinforcing barrel is in close contact with a mud layer. The reinforcing barrels of the reinforcing assembly and the main supporting piece can form a whole and jointly act, the overall rigidity of the wind turbine foundation is improved, the overall horizontal bearing capacity of the wind turbine foundation is improved, the corner of the main supporting piece on the surface of a mud layer is reduced, and the safety requirement of the wind turbine foundation is better met.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a construction method for a fan foundation, a fan foundation and a wind power generating set. Background technique [0002] Wind power is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some restrictions on the utilization of onshore wind energy, such as large land occupation and noise pollution. Due to the abundance of offshore wind energy resources and the feasibility of today's technology, the ocean will be a rapidly growing wind power market. [0003] With the development of offshore wind power to deep water, the environmental conditions are getting worse, and higher requirements are placed on the horizontal bearing capacity of wind turbines. At present, the most commonly used form of offshore wind power foundation is the large-diameter single-pile foundation. For offshore wi...
