Support foundation for solar photovoltaic power station and onsite construction method for support foundation

Abstract

The invention provides a support foundation for a solar photovoltaic power station and an onsite construction method for the support foundation. The support foundation comprises a central post, a base, a tubular section and earthwork, wherein the central post, the base and the tubular section are precast, and the earthwork is filled on site. The base is arranged at the bottom of the central post which is positioned in the center of the upper portion of the base, the tubular section is arranged on the base, the planar size of the tubular section is not larger than that of the base, a cavity is formed between the tubular section and the central post and filled with the earthwork, and the weight of the earthwork accounts for a part of the total weight of the support foundation. More than 30% concrete consumption can be reduced by means of the technical scheme as compared with an existing solid foundation technical scheme. Since concrete is smaller in intrinsic weight, precast work amount, logistics freight volume and onsite workload are correspondingly reduced, and the design weight of the support foundation is not reduced after the cavity is filled with the earthwork. By means of the support foundation, construction period of the photovoltaic power station can be greatly shortened while construction cost of the photovoltaic power station is greatly reduced.

Description

technical field [0001] The invention relates to a support foundation for a solar photovoltaic power station and an on-site construction method thereof. Background technique [0002] At present, a large number of solar photovoltaic power stations use brackets to support the installation of photovoltaic module panels. Each bracket column needs to be equipped with a component foundation. Most of the current methods are cast on site. Because the sites of large-scale solar photovoltaic power stations are often located in desertified areas (deserts, Gobi deserts, rocky desertification slopes, swamps, waterfront tidal flats, etc.), construction materials and construction equipment are relatively scarce, so the current on-site construction methods for support foundations are expensive. High quality, poor quality, long construction period, more labor and materials, more construction machinery invested, and more difficult construction management. This is extremely detrimental to redu...
