Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mountain photovoltaics, in particular to a photovoltaic foundation and a photovoltaic bracket. Background Art
[0002] In order to make full use of land resources, single-column fixed supports are mostly used in mountains with gentle slopes. According to different terrain and geological conditions, combined with the support structure type and installation requirements, the support foundation mostly adopts a single pile foundation (including bored piles, steel spiral piles, prefabricated piles, etc.). The diameter of a single pile foundation is generally not less than 250mm, and the depth of burial is not less than 1.5m. In order to improve construction efficiency, crawler down-the-hole drills or crawler short spiral drills and similar equipment are generally used for construction. Crawler drills have a larger body size and higher requirements for terrain conditions. They are suitable for construction on hillsides with gentler terrain. When the slope is large and the terrain is rugged, it is often necessary to excavate a construction access road for construction, which has high construction costs and causes certain damage to the environment.
[0003] The karst rocky desertification mountains are eroded by rainwater, and the surface stalagmites and stone buds are exposed. Before the construction of the photovoltaic support pile foundation, it is necessary to use an excavator breaker to break and level them one by one, which is a huge project. For some areas with high exposed surface rocks, very rugged terrain, and rocky terrain near cliffs, the construction cost of using large crawler drilling rigs is very high and the efficiency is low, and the use of traditional single pile foundation forms is subject to certain restrictions.
