Description

Technical Field

[0001] This utility model relates to the field of wind power beam and slab technology, specifically to a prefabricated onshore wind power beam and slab foundation structure. Background Technology

[0002] The working principle of a wind turbine is relatively simple. The wind turbine rotates under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the turbine shaft. The generator rotates and generates electricity under the drive of the turbine shaft. There are many types of wind turbines, including large, small and household models. Wind turbines are mainly used in rural areas, pastoral areas, mountainous areas and other areas with abundant wind resources. When installing a wind turbine, a stable base is required to improve the stability of the installation.

[0003] Traditional wind turbine tower foundations typically employ fully cast-in-place concrete structures. While simple to construct and widely adaptable, they suffer from drawbacks such as large concrete consumption, difficulties in centralized supply, long overall construction periods, and potential material waste and environmental pollution. On the other hand, traditional wind turbine tower foundations generally utilize gravity spread foundations, typically consisting of a base slab, frustums, and piers. These foundations rely on the self-weight of the foundation and backfill soil to resist loads transmitted from the upper tower. While simple in construction and convenient to install, their thicker base slabs result in larger quantities of concrete and steel reinforcement, and are significantly affected by the bearing capacity of the soil, making it difficult to fully utilize the material strength.
