With the reduction of the price of photovoltaic modules in the photovoltaic market, the price of the entire system should also be reduced as much as possible. This also puts forward corresponding requirements for the installation of solar mounting system, that is, it is fast to reduce working hours and environmental protection. In the power station project, the foundation part bears the brunt. First, it is in contact with the soil and solarbracket, which has the greatest impact on the vegetation of the environment. Second, this part is the first step of installation. Only when the foundation is completely stable can it be installed.

Traditional ground power station foundations are mostly concrete foundations, but concrete foundations have many constraints.

1.A curing time is required after the concrete is poured. After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, resulting in a dehydration phenomenon, which will make the cement particles that have formed a gel not fully hydrated and cannot be converted into stable crystalsandlack of sufficient adhesionresulting in flaky or powdery exfoliation on the concrete surface. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks, which will affect the durability and integrity of the concrete.

2.Using a concrete foundation requires a large amount of fresh water. Calculated according to the engineering volume of 1MW, estimated according to C20, about 1500 concrete independent foundations are required, and about 42m³ of water consumption is required according to the mixing ratio. Such projects, in arid areas such as deserts, will cause a great waste of water resources.

3.The use of concrete foundations requires a larger working surface, which will cause greater damage to the natural ground.

The application of grounding screw can make up for the above shortcomings.

1.In the production process of grounding screw, the production line consists of blanking - high temperature heating - tube shrinking - spiral sheet production - spiral sheet welding - surface hot-dip galvanizing and other processes according to different specifications of screw pile models. We adopt fully automatic welding equipment for the welding of threaded pieces, which can effectively reduce the instability of the welding seam caused by manual welding, and improve the production efficiency.

2.During the installation process, the grounding screw is installed by a special piling machine, and the positioning and installation of a screw pile foundation can be completed in 3 minutes. For the 10MW screw pile foundation project, the entire project installation can be completed within 40 days.

3.After use, the screw pile can be pulled out for disposal and then recycled, so that the cost of materials and the pollution to the environment can be minimized.
