Product Description
This ramming pile ground solar module mounting system is mounting structure which columns are foundation piles and are driven directly into the soil. The pile foundation primarily relies on pile side friction and pile end resistance to bear the load from the superstructure, transferring the weight of the PV modules, wind load, snow load, etc., to the stable soil layer below.
Based on the driving method, the driving of piles can be divided into hydraulic pile hammer type and static pile driver type. This product requires no concrete pouring; a piling machine hydraulically drives steel columns into the ground to the required depth, in just a minute, greatly improving construction efficiency.

Advantage
▶ Fast Construction Speed and High Efficiency:
Piling machines are directly driven into earth, in just a minute. Compared to traditional concrete foundations, significant time is saved on excavation, formwork, pouring, and curing.
▶ Economical and Highly Efficient with Low Overall Costs:
No concrete materials are required, eliminating the costs of steel reinforcement, cement, and the time. The components are designed into standard specfications for fast mass production and fast delivery. Piling is done by mahines, and it will significantly reduce labor costs.
▶ Environmentally Friendly with Minimal Ecological Damage:
By piling machine, the pile can be easily adjust, and almost no site leveling is required. Compared to concrete foundation, there is no excavation or backfilling work, resulting in minimal damage to existing vegetation and eliminating dust and waste emissions. The piles can also be recycled after service life, making this solution highly environmentally friendly.
▶ High Adaptability and Good Terrain Compatibility:
Single or double column designs can adapt to undulating terrain, slopes, and undulating ground.
▶ Safe, reliable, corrosion-resistant, and durable:
Utilizing hot-dip galvanized or ZAM surface treatment, the carbon steel components possess exceptional corrosion resistance, adapting to diverse climatic environments. The overall structure has been calculated for use in extreme weather and geographical conditions.
▶ Easy installation and maintenance:
All components are bolted together, no welding work on site, which makes maintenance easy.
▶ Excellent wind and snow resistance:
The all-carbon steel design ensures long-term reliability of the system under harsh weather conditions such as blizzards and strong winds.

Applicable Scenarios
Ground-mounted photovoltaic (PV) systems using piling are widely used in various types of ground-mounted PV power plants, primarily including:
▪ Large-scale ground-mounted PV power plants:
The most common application scenario, suitable for large-scale PV projects in open areas.
▪ Mountain/hilly PV projects:
Piling foundations penetrate weak layers to transfer loads to hard rock and soil, making them particularly suitable for complex terrain and mountainous projects.
▪ Agricultural-photovoltaic projects:
Meeting the basic needs of agricultural production while also providing PV power generation, piling foundations offer good permeability in the pile foundation area, beneficial for agricultural production activities.
▪ Winter construction projects:
Piling foundations can still be constructed normally under winter weather conditions.
Important Notes:
▶ Important On-Site Geological Survey:
A professional geological survey must be done before construction to determine the soil type and bearing capacity. Geotechnical investigation is a prerequisite for selecting the appropriate pile type and determining the driving depth; blind construction based on estimation is strictly prohibited.
▶ Precise Pile Positioning:
Before pile driving, measurements must be taken according to the design drawings to determine the precise position of each pile. Ensure that the spacing and elevation of piles throughout the site meet design requirements.
▶ Construction Method Selection and Process Control:
Steel piles should preferably be driven using a clamp-type hydraulic hammer machine, or static pressing pile driver. The pile driving depth must be strictly controlled according to the design value; controlling the pile elevation and pile position deviation is critical in construction quality control.
▶ Installation Accuracy Control:
During installation, ensure that the verticality of the columns (verticality ≤ 1mm), the horizontality of the beams, and the tilt angle of the mounting system meet the design requirements. The horizontal deviation along the entire east-west length (at the same elevation) should be ≤ 10mm.
▶ Load Verification:
For areas with large wind and snow loads, a professional structural design verification is required. Wind and snow loads should be calculated using values with a return period of 25 years.
▶ Test & verification:
Before formal construction, it is recommended to conduct tests to verify the bearing capacity of individual piles (including compressive, pull out, and horizontal bearing capacity) to verify the rationality and reliability of the design.
▶ Site protection and environmental restoration:
After construction is completed, temporary construction facilities should be promptly dismantled and cleaned up, and the affected surface environment should be restored to minimize damage to the site's ecological environment.
