Basic structure of a wind turbine

Abstract

The invention discloses a foundation structure for a wind-driven generator. The foundation structure comprises a foundation pit and a plurality of stand tubular piles, wherein at least three circles of concentric tubular pile insertion holes are formed in the bottom surface of the foundation pit, and are circumferentially and uniformly distributed; the stand tubular piles are inserted into two circles of tubular pile insertion holes in the inner side respectively, are fixed by filled concrete, and are used for connecting a mounting stand of the wind-driven generator; a plurality of reinforcing tubular piles are inserted into the tubular pile insertion holes positioned in the outer side of the stand tubular piles, and are fixed by filled concrete, and the upper ends of the reinforcing tubular piles are higher than the bottom surface of the foundation pit; a reinforcement cage is fixedly poured in the foundation pit, and is used for connecting the stand tubular piles with the reinforcing tubular piles; the lower end of the mounting stand is fixedly connected with the upper ends of the stand tubular piles; the lower part of the mounting stand is fixedly poured in a concrete lug boss above the foundation pit. The foundation structure has the beneficial effects that the foundation structure is simple, convenient to construct, short in construction cycle and high in compressive resistance and overturning moment resistance; the mounting stand can be firmly fixed on the ground; the firmness of the stand tubular piles can be improved, and the compressive resistance and the overturning moment resistance of the foundation structure can be improved.

Description

technical field [0001] The invention relates to a construction foundation, in particular to a wind power generator foundation structure. Background technique [0002] Wind generator is a device that converts wind energy into electrical energy. Because it utilizes natural wind energy, it has been paid more and more attention to and utilized by people as the country vigorously advocates energy conservation and environmental protection. [0003] At present, there are mainly three types of foundations for wind turbines installed on the ground: [0004] 1. Solid gravity foundation. This kind of foundation is completely stable by its own weight or the soil and rocks loaded on it. The amount of concrete is large, and the amount of foundation excavation and soil and rock backfilling is large. This kind of foundation has strong compressive capacity, but The ability to resist overturning moment is low. [0005] 2. Pillar-fixed foundation. This kind of foundation adopts the method of...

AI Technical Summary

Problems solved by technology

Although the construction cost of this kind of foundation is high and the construction is difficult, the foundation has strong compressive capacity and overturning moment resistance.
