Embodiment Construction

[0029] Such as figure 1 As shown, a barrel-type assembled wind power tower foundation of the present invention includes a cast-in-place platform column 1 for connecting the wind power tower tube, a prefabricated bottom barrel 2 arranged at the bottom of the cast-in-place platform column 1, and the cast-in-place platform column 1 is cylindrical. The bottom of the prefabricated bottom bucket 2 is open and the lower end of the prefabricated bottom bucket 2 is vertically inserted into the rock foundation; the entire tower foundation is inserted into the rock foundation through the prefabricated bottom bucket 2, and the bottom of the prefabricated bottom bucket 2 is placed on the rock, which is inconvenient to embed Rocks may not be embedded in rocks. Compared with the existing pile foundation, the contact area between the prefabricated bottom barrel 2 and the foundation soil layer is larger, which increases the friction between the foundation cylinder body and the soil layer, and ...

Abstract

The invention discloses a barrel-shaped assembly type wind power tower drum foundation and a construction method thereof, and belongs to the technical field of wind power generation, the barrel-shaped assembly type wind power tower drum foundation comprises a cast-in-place stand used for being connected with a wind power tower drum and a prefabricated bottom barrel arranged at the bottom of the cast-in-place stand, and the bottom of the prefabricated bottom barrel is open and is inserted into the foundation in the vertical direction; the prefabricated bottom barrel comprises a plurality of arc-shaped bottom barrel pieces, the arc-shaped bottom barrel pieces are sequentially spliced in the circumferential direction, and every two adjacent arc-shaped bottom barrel pieces are connected through a connecting structure. The foundation barrel is in the shape of a circle formed by mutually splicing the arc-shaped blocks and is suitable for a foundation with many rocks, the installation stability between the foundation and the foundation can be improved, and the bearing capacity of the tower barrel foundation can be improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a barrel-type assembled wind power tower foundation and a construction method thereof. Background technique [0002] The wind turbine tower is a towering structure that bears large horizontal and vertical loads, so the foundation is relatively large. The bottom of the traditional wind power tower pile foundation is generally fixed by multiple pile foundations and the foundation. However, when the foundation rocks in the lower part of the foundation are many and hard, and it is inconvenient to embed the piles into the rocks, it is inconvenient to use pile foundation construction, resulting in load bearing capacity of the pile foundation. Poor capacity and stability. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a barrel-type assembled wind power tower foundation and its construction method. The f...
