Problems solved by technology

[0005] The inventors found that in actual engineering, wind farms must be arranged on plains and hills with sufficient wind resources and away from urban areas, and the distance between each wind turbine is relatively long. It is very difficult, and the existing engineering projects show that there are great disadvantages in the connection form between the upper column and the lower foundation, and there are often engineering problems such as cracks, corrosion, and water return at the joints

Embodiment 1

[0045] Such as figure 1 , figure 2 with image 3 As shown, Embodiment 1 of the present disclosure provides a wind turbine assembly integrated foundation structure, including: prefabricated concrete foundation 1, wind turbine finished steel foundation 2, secondary grouting 3 (that is, the slurry in the groove), anchorage 4. Horizontal bars 5 and anchor bars 6 in the grouting layer.

[0046] The central area of ​​the top surface of the precast concrete foundation 1 reserves a groove for later installation and grouting. The groove adopts the structural form of the bottom reaming. In this embodiment, the groove is from top to bottom along the vertical axis of the groove. The shape of the horizontal cross-section is the same and the horizontal cross-sectional area gradually increases.

[0047] It can be understood that, in some other embodiments, the horizontal cross-sectional area of ​​the groove increases gradually from top to bottom along the vertical central axis of the gro...

Embodiment 2

[0055] Such as Figure 4 As shown, embodiment 2 of the present disclosure provides a method for preparing a wind turbine assembly monolithic infrastructure, including the following process:

[0056] One end of the vertical prestressed tendon is poured at the same time as the precast concrete foundation, and the remaining part of the vertical prestressed tendon passes through the vertical reinforcement casing to apply prestress on the upper surface of the fan steel foundation, and through the fixing piece on the surface of the fan steel foundation Fixing, the remaining part of the vertical prestressing tendon extends upwards to the upper part of the slurry in the groove and welds with the anchoring tendon;

[0057] One end of the oblique prestressed tendon is poured at the same time as the precast concrete foundation, and the remaining part of the oblique prestressed tendon passes through the oblique reinforcement casing obliquely to apply prestress on the surface of the fan st...

Abstract

The invention provides an integral type foundation structure for assembling a wind driven generator and a preparation method of the integral type foundation structure. The integral type foundation structure comprises a concrete foundation, vertical prestressed tendons, inclined prestressed tendons and horizontal reserved tendons; grooves used for containing a fan steel foundation structure and slurry are formed in the top of the concrete structure; one ends of the inclined prestressed tendons are poured in the concrete foundation, and the other ends of the inclined prestressed tendons penetrate through an inclined reinforcing sleeve on the fan steel foundation structure; one ends of the vertical prestressed tendons are poured in the concrete foundation, and the other ends of the vertical prestressed tendons penetrates through a vertical reinforcing sleeve on the fan steel foundation structure; one ends of the horizontal prestressed tendons are poured in the concrete foundation, non-shrinkage slurry is poured in the grooves; and the other ends of the horizontal prestressed tendons are connected to grouting layer horizontal tendons in the slurry. According to the integral type foundation structure and the preparation method thereof, the concrete quality is improved, the integrity of the foundation structure is guaranteed, materials are saved, construction and installation are convenient, and the construction period is greatly shortened.

Description

technical field [0001] The present disclosure relates to the technical field of industrial building structures, in particular to an assembled integral basic structure of a wind power generator and a preparation method thereof. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Wind energy is an inexhaustible, inexhaustible and non-polluting renewable resource that is naturally produced. It is a kind of available energy provided to human beings due to the work done by air flow, and is widely used in the power generation industry. . [0004] The core part of the wind power generation project is the wind turbines. At present, the wind turbines and their columns are supplied by the wind turbine manufacturers as a whole, with a high quality assurance rate. The column is connected to the lower foundation by anchor bolts and the like. [0005] ...
