[0002] A wind turbine foundation is the foundation structure used to install and secure the wind turbine tower, primarily serving as a stabilizing factor. A wind turbine foundation generally consists of a concrete platform and a foundation ring. The foundation ring is partially buried within the concrete platform, so the connection between the foundation ring and the concrete platform requires high waterproof performance.

[0003] Chinese patent publication number CN218405525U discloses a waterproof structure for a wind turbine foundation in a wind farm. The structure comprises a concrete platform, a foundation ring, a first waterproof filling portion, a second waterproof filling portion, and a waterproof coating layer. A first groove is defined on the top surface of the concrete platform, and the bottom end of the foundation ring is embedded in the concrete platform through the bottom of the first groove. A fixing component is disposed within the first groove, and a notch is defined at the top of the fixing component, adjacent to the outer ring wall of the foundation ring. The notch and the outer ring wall of the foundation ring together form a second groove. Both the first and second waterproof filling portions are disposed within the second groove, and a waterproof coating layer covers the connection between the foundation ring and the fixing component. This waterproof structure, by providing the first and second waterproof filling portions within the second groove, provides a dual waterproofing effect.
