Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a: a single-column photovoltaic support foundation in a large-gradient area is shown in figures 1-2 and comprises 3 bottom foundation piles which are distributed in an array mode and are obliquely and outwards opened from top to bottom, wherein a top foundation is arranged at the top of each bottom foundation pile, a support column bottom end plate 6 is fixedly arranged on the top surface of each top foundation pile, and the bottom foundation piles and the top foundation piles are of an integrally cast structure; the bottom foundation pile comprises a reinforcement cage 4 arranged in the inclined hole, and concrete 3 is poured outside the reinforcement cage 4 to form the bottom foundation pile; the top foundation comprises a plurality of U-shaped bolts 5,U arranged at intervals, concrete 3 is poured among the U-shaped bolts 5 to form the top foundation, and head ends of the U-shaped bolts 5 extend out of the top foundation and penetrate through bottom end plates 6 of the support columns.
The utility model discloses an among this structure, bottom foundation pile is subject to the influence of drilling size, can't make jumbo size single pile structure, so select to be display distribution, and by the top to the bottom slant to open the bottom foundation pile structure that sets up, every bottom foundation pile can adopt artifical drilling back like this, places steel reinforcement cage 4 and pours concrete 3 and form. And adopt 3 bottom foundation piles to support the top basis jointly, can support the top basis well, the bottom foundation pile sets up for the slope, and its support effect is better. The bottom foundation pile and the top foundation are of an integrally cast structure, the manufacturing is more convenient, and after the integrally formed structure is a whole, the integral supporting strength is better than the split connection effect. The support column bottom end plate 6 is used for welding the photovoltaic support column.
Inside steel reinforcement cage 4 upwards extends to the top basis, behind later stage concreting 3, can make bottom foundation pile and top basis link together well, form a complete whole, the support effect is better.
The diameter of inclined hole is 150mm, can adopt artifical drilling to form, has solved the problem that can't use mechanical construction in the region of heavy grade.
The top foundation is a cylindrical pile, and the bottom surface of the cylindrical pile completely covers the top surfaces of the 3 bottom foundation piles. The structure enables all parts of the bottom foundation pile to participate in supporting the top foundation, and the supporting effect is better.
The support column bottom end plate 6 is fixed with the concrete of the top foundation by pouring, and the support column bottom end plate 6 is guaranteed to be well fixed with the top foundation.
The top of the bottom foundation pile extends upwards to the surface of the platform 2, the platform 2 is of a platform structure chiseled on the hillside 1, and the top foundation is arranged upwards from the surface of the platform 2. In the construction process, firstly, a platform 2 is chiseled on the hillside 1, and then an inclined hole is drilled on the platform 2.
