Existing photovoltaic systems, such as the photovoltaic tracking system shown in fig. 1, take the form of a single shaft with no other connections between the supports other than the linkage structure required for tracking. Similar tracking systems therefore place extremely high demands on the rack foundations 11 to ensure that each rack can cope individually with external loads such as wind loads, and in particular with particularly harsh environments such as high winds and storms. Therefore, the support foundation 11 of the photovoltaic tracking system in the prior art usually adopts a foundation which needs to be buried underground, such as a precast tubular pile, a cast-in-place pile, a steel pipe pile, a screw pile and the like. However, similar support foundations cannot be applied to similar areas such as sandy land and coal mining subsidence areas, and the similar support foundations need to be transported to an installation site after being manufactured in a factory in advance, and need to be installed on the site by professional large-scale engineering machinery, so that the production cost is high, and time and labor are wasted. Especially, similar support basis is disposable installation, and the required precision of lower stake is very high during the installation, easily causes the big and unable adjustment scheduling problem of pile spacing error, moreover, when photovoltaic project need move under the special circumstances, the basis that has buried underground all caused destruction to the soil environment no matter tear open and remain.
