Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The utility model provides a honeycomb wind-powered electricity generation basis, include:

the stand column 3 is used for supporting a main body of the wind generating set;

the supporting structure 2 is fixedly connected with the outer peripheral side of the table column 3, and the supporting structure 2 is in a honeycomb shape and is provided with a plurality of honeycomb units;

the side wall 1, the side wall 1 and the supporting structure 2 are fixedly connected with one side far away from the table column 3;

the anchor bolt 4 is arranged inside the pillar 3.

In order to enhance the stability of the supporting structure 2, a filler 5 is disposed in each honeycomb unit, in this embodiment, the filler 5 is backfill soil, in some embodiments, the filler 5 may be sand, soil, gravel, and the like, and the amount of the filler 5 needs to be filled according to actual bearing requirements. In other embodiments, no filler 5 is provided within the honeycomb cells.

In view of the support stability of the support structure 2, an excessively large footprint of a single cell may result in sparsely distributed cells in the support structure 2, thereby reducing the support stability of the support structure 2, such that the single cell is no greater than 6 meters on a side in the support structure 2. In order to further enhance the supporting stability of the supporting structure 2, in the present embodiment, the honeycomb units in the supporting structure 2 are distributed in a rotational symmetry manner; in some embodiments, the honeycomb cells in the support structure 2 are distributed in a central symmetry; in other embodiments, the honeycomb cells in the support structure 2 are distributed Zhou Duichen; in other embodiments, the cells in the support structure 2 may be distributed in an unordered manner, depending on the actual terrain, load bearing requirements, and support requirements.

Considering when carrying out the construction to wind-powered electricity generation basis, need dig out the construction hole that can hold wind-powered electricity generation basis earlier on the ground, but because the geographical factor influence of construction location, the construction hole bottom surface can have the condition that is unsuitable directly to carry out the construction of bearing structure 2 because reasons such as topography, geology, consequently is provided with the bottom plate in
