Photovoltaic support foundation structure applicable to tidal flat photovoltaic power station and construction method

Abstract

The invention relates to a photovoltaic support foundation structure applicable to tidal flat photovoltaic power station and a construction method. The structure comprises foundations arranged on the ground, and the photovoltaic support is arranged on the foundations and comprises front columns and rear columns. The front columns and the rear columns are arranged on the different foundations. The structure is characterized in that connectors are pre-buried at the tops of the foundations, and the photovoltaic support is connected with the foundations through the connectors. The sections of the foundations are rectangles with 0.2m-0.4m side lengths or circles with 0.2m-0.4m diameters. The foundation length is in a range of 2m to 5m. According to the structure and the construction method, stress is reasonable and reliable, force transmission ways are clear, the concrete usage amount is small, the earth excavation volume is not needed, construction precipitation is not needed, the cost is low, the consumption labor is little, the construction speed is fast, the durability is high, the structure is particularly applicable to tidal flat positions which are weak in foundation bearing capacity, difficult in earth excavation, shallow in underground water level and high in corrosion.

Description

technical field [0001] The invention relates to a simple strip-shaped foundation suitable for a fixed support of a photovoltaic module in a solar ground photovoltaic power station. Background technique [0002] In a photovoltaic power station, the components used to realize photoelectric conversion are called photovoltaic modules. The photovoltaic bracket is a steel (or aluminum alloy) bracket used to support the photovoltaic module. The photovoltaic bracket is equipped with a photovoltaic bracket foundation to meet the carrying capacity and normal use requirements. Photovoltaic supports are generally arranged in the open air on a vast open space, and there are also photovoltaic supports arranged on roofs, ash yards, and greenhouses, but tidal flat photovoltaic power stations are still rare. So far, the more commonly used photovoltaic support foundations include reinforced concrete independent foundations, spiral steel pile foundations, etc., but due to the particularity of ...

Problems solved by technology

[0006] The main disadvantages of the spiral steel pile foundation are: the project cost is relatively high, and special construction machinery is required. The most important thing is that the horizontal bearing capacity of the foundation is closely related to the compactness of the soil layer. The spiral steel pile foundation requires the soil layer to have a certain degree of compactness. property, especially the shallow soil close to the surface should not be too loose or too weak

In fact, tidal flats a
