specific Embodiment

[0033] see figure 1 , 2 , 3, 4, and 5, the present invention includes: concrete cushion 1, concrete base plate 2, 8 hollow prefabricated cantilever beams 3, 8 hollow edge beams 4, concrete pier 5, prestressed anchor bolt 6, The concrete cushion 1 is in the shape of a ring. After the concrete cushion 1 is completed, the overall structure of the concrete base plate 2 and the concrete pier 5 is made on it. The middle part of the concrete base plate 2 is provided with a circular concrete pier 5 . At the same time, the finalized prefabricated cantilever beam 3 is manufactured in the concrete prefabrication production. A ring-shaped beam 4 is provided near the edge of the concrete base plate 2 . The prefabricated cantilever beams 3 are transported to the site and installed on the foundation of the wind turbine. One end of each prefabricated cantilever beam 3 is connected to the concrete column pier 5 to form a rice-shaped structure, and the other end is placed between two adjacen...

Abstract

The invention discloses a wind power generation tower foundation with prefabricated foundation prestressed beams and slab. The wind power generation tower foundation with prefabricated foundation prestressed beams and slab comprises a concrete cushion on which a concrete foundation slab is arranged; a circular-arc-shaped concrete column pier is arranged in the middle of the concrete foundation slab; edge small beams are arranged on parts, close to edges, of the concrete foundation slab, and the circular-arc-shaped concrete column pier and the edge small beams, and two adjacent edge small beams are connected by means of prefabricated cantilever beams; prestressed anchor bolts are uniformly buried in the concrete column pier, and one end of each prestressed anchor bolt is connected with a lower foundation anchor plate, while the other end of the same is connected with a tower tube; voids are uniformly formed in the prefabricated cantilever beam, and the prefabricated cantilever beams are in prestressed connection with the concrete foundation slab by using prestressed bolts in the voids. Rigid connection of the tower tube with the foundation is guaranteed, the amount of the steel utilized is reduced, and the construction of such a part is also simplified simultaneously.

Description

technical field [0001] The invention relates to a foundation structure of a wind power generation tower, in particular to a base prefabricated prestressed beam plate type wind power generation tower foundation. Background technique [0002] At present, the foundation of the wind power tower on the medium-hard foundation soil mostly adopts an independent expansion foundation, which is composed of the base cantilevered floor, column piers and foundation ring, and is a pressure-bearing beam-slab foundation. The combination of independent expansion foundation and appropriate foundation conditions can achieve better compressive bearing capacity, so it is often used in building column foundations. But for wind power towers, the main force of the superstructure on the foundation is not the pressure but the bending moment. Therefore, the traditional independent expansion foundation has more than enough compression resistance and insufficient bending resistance, thus causing a large ...
