Embodiment Construction
[0033] like Figure 1~2 As shown, a light-weight assembled wind power structure foundation of the present invention includes a central pillar 1, and several groups of radial support components 2 that are uniformly distributed on the outside of the central pillar 1 in a ring centered on the central pillar 1; the central pillar 1 is in the form of a ring , can reduce the overall quality, and reduce the soil volume between excavation of various rib beams. The radial support assembly 2 includes a prefabricated outer bottom plate 3, a prefabricated inner bottom plate 4, a first prefabricated rib beam 5, and a second prefabricated rib beam 6. The prefabricated inner bottom plate 4 is arranged at the bottom of the central pillar 1, and its enclosed shape is the same as that of the central pillar 1. bottom fit. The prefabricated outer floor 3 is horizontally connected to the prefabricated inner floor 4 through the second prefabricated rib beam 6, one end of the first prefabricated ri...

The invention discloses a lightweight assembly type wind power structure foundation and an assembly method thereof, and belongs to the technical field of wind power equipment, the foundation comprises a central stand, and a plurality of groups of radial support assemblies annularly and uniformly distributed on the outer side of the central stand by taking the central stand as a center; the radial supporting assembly comprises a prefabricated outer bottom plate, a prefabricated inner bottom plate, a first prefabricated rib beam and a second prefabricated rib beam, the prefabricated inner bottom plate is arranged at the bottom of the center pillar, one end of the first prefabricated rib beam is connected with the prefabricated outer bottom plate, the other end of the first prefabricated rib beam is obliquely connected to the center pillar, and the prefabricated outer bottom plate is horizontally connected to the prefabricated inner bottom plate through the second prefabricated rib beam; every two adjacent prefabricated inner bottom plates are connected, and every two adjacent prefabricated outer bottom plates are connected. The foundation and the assembling method can be used for rapidly assembling the wind power structure foundation, the installation efficiency is improved, and the transportation and installation cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of wind power equipment, and in particular relates to a lightweight assembled wind power structure foundation and an assembly method thereof. Background technique [0002] The wind turbine tower is a towering structure with a large scale and bears large horizontal and vertical loads, so the foundation shape of the wind turbine tower is also large. The traditional reinforced concrete foundation uses a lot of concrete, and the spacing between the steel bars is dense. The concrete is not easy to pour, and the on-site construction is difficult and inefficient. Contents of the invention [0003] In view of this, the object of the present invention is to provide a light-weight assembled wind power structure foundation and its assembly method, which can be used for rapid equipment of wind power structure foundation, improve installation efficiency, and reduce transportation and installation costs. [0004] To ac...
