Example
[0063] Second embodiment:
[0064] Please refer to Figure 11 , This embodiment provides an onshore fan foundation 100 , the overall structure, construction process and technical effects obtained are basically the same as those of the first embodiment, the difference lies in the specific structure of the tensioning member 141 .
[0065] In this embodiment, the tension member 141 adopts a pull rod 149 . Specifically, each pull rod 149 is hinged by a plurality of rod members 148 in sequence.
[0066] Like the cable of the first embodiment, the above-mentioned tie rod 149 has the characteristics of simple structure and convenient installation, which can ensure the tightening effect on the tower tube 210, thereby improving the bending resistance of the tower tube 210, thereby improving the foundation of the entire onshore wind turbine. 100 reliability.

The invention provides an overland fan foundation, a foundation construction method and a fan and belongs to the technical field of wind-driven power generation. The overland fan foundation comprises a foundation ring, a plurality of ground beams and a plurality of ground piles, wherein the ground beams are in one-to-one correspondence with the ground piles, one end of each ground beam is connected with the foundation ring, and the other end of each ground beam is connected with the corresponding ground pile. The foundation construction method comprises the step of building the overland fan foundation. The fan comprises a fan main body and the overland fan foundation, wherein the fan main body comprises a tower tube, and the bottom of the tower tube is connected with the foundation ring of the overland fan foundation. The overland fan foundation combines the advantages of a gravity type foundation and a pile foundation, has excellent reliability and stability, can adapt to various work terrains, can reduce steel material usage and reduce cost and can also improve the deformation resistance of the tower tube. The fan adopting the overland fan foundation has the characteristics of high reliability, wide work terrain adapting range, low construction cost and strong tower tube deformation resistance.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to an onshore wind turbine foundation, a foundation construction method and a wind turbine. Background technique [0002] The depletion of traditional energy sources, the pressure of energy supply security and environmental protection, forcing people to pay attention to renewable energy, as a clean and renewable wind energy development and utilization has received high attention. Wind energy has the advantages of saving resources, preventing environmental pollution, and being renewable. It is a new type of renewable energy with the most mature technology and the most large-scale development in the current clean energy field. The foundation is the core of the wind turbine and the carrier of the tower and the entire power generation device. If there is a problem with the foundation, it will lead to major accidents such as the scrapping of the whole wind turbine, and it i...
