Description

Technical Field

[0001] The utility model discloses a branch - disk type foundation for pebble foundation, belonging to the technical field of foundation engineering. Background Art

[0002] In the development process of the photovoltaic industry, the support foundation, as an important part of the photovoltaic system, plays a key role in ensuring the safe, stable and efficient operation of photovoltaic modules. However, when photovoltaic projects are deployed on foundations rich in large - sized pebbles, traditional foundation forms often face challenges in adaptability and construction efficiency.

[0003] For traditional reinforced concrete pile foundations, it is difficult to form holes in pebble foundations and hole collapse is likely to occur, which not only reduces construction efficiency but also increases the diameter of the pile foundation and the amount of concrete used, resulting in material waste and increased costs. In addition, driven pile foundations such as precast piles, prestressed pipe piles and steel section piles are also difficult to be effectively applied in pebble foundations because they require pre - drilling and are prone to material waste and unstable caulking quality during the caulking process. At the same time, screw steel piles cannot effectively rotate into large - sized pebble foundations and thus cannot meet the requirements of such special foundations.

[0004] Although the spread foundation is an alternative, its concrete consumption is much higher than that of bored piles, which not only increases costs but also lengthens the construction period. And although the reinforced concrete strip foundation can be used as a solution, its construction speed is slow and its economy is poor. Summary of the Invention

[0006] The branch - disk foundation is arranged at the bottom end of the column and fixedly connected with the column;

[0007] One end of each foundation brace is fixed on the branch - disk foundation, and the other end is fixed at a preset height of the column.

[0008] Preferably, the branch - disk foundation is a reinforced concrete structure with criss - cross arrangement.

[0009] Preferably, the branch - disk foundation is one of a triangle, a square or a circle.

[0010] Preferably, multiple foundation braces are evenly arranged around the outer edge of the branch - disk foundation.

[0011] Preferably, the bottom end of the column is arranged at the center of the branch - disk foundation.

[0012] Preferably, the branch - disk foundation is an isosceles right - angled triangle;

[0013] The bottom end of the column is fixed at the right-angle position of the branch-disk foundation in the shape of an isosceles right triangle.

[0014] Preferably, there are two foundation braces.

[0015] One end of each of the two foundation braces is respectively fixed at two acute-angle positions of the branch-disk foundation in the shape of an isosceles right triangle, and the other ends are both connected to the column.

[0016] Preferably, the foundation braces can be made of one or more of angle steel, round pipe, C-shaped steel, and H-shaped steel.
