Reinforced concrete independent foundation for photovoltaic brackets
The reinforced concrete independent foundation is one of the earliest and most traditional forms of photovoltaic bracket foundations, and it is also a widely applicable foundation type. It involves setting reinforced concrete independent foundations under the front and rear columns of the photovoltaic brackets, consisting of a foundation bottom slab and short columns on top of the slab.
The top of the short columns is equipped with embedded steel plates (or embedded bolts) to connect with the upper photovoltaic brackets. This type of foundation requires a certain burial depth and a sufficient foundation base area. The foundation bottom slab is covered with soil, and the weight of the foundation, along with the weight of the covering soil, works together to resist uplift forces caused by environmental loads. A larger foundation base area is used to distribute the vertical load of the photovoltaic bracket downward, while the friction between the foundation base and the soil, as well as the resistance from the foundation's sides and the soil, helps to resist horizontal loads.
The advantages of the reinforced concrete independent foundation include clear force transmission paths, reliable load-bearing capacity, wide applicability, and no need for specialized construction machinery. This type of foundation has a strong ability to resist horizontal loads.
