Precision driving of photovoltaic (PV) piles is a precise construction technique used for the installation of PV power plant support foundations. It involves vertically pressing precast piles into the ground using specialized equipment to form a stable support structure. Unlike traditional piling, precision driving uses static pressure, avoiding the impact of vibration on the surrounding environment. Simultaneously, it uses precision instruments to control the verticality and depth of the piles, ensuring installation accuracy. This technology is particularly suitable for PV projects in soft geological conditions.
Key Processes of Precision Driving Pile Construction:
Site Survey: Detailed analysis of geological conditions to determine pile specifications and driving depth.
Pile Position Layout: Precise positioning of each pile using a total station.
Static Pressure Construction: Smooth pressing using hydraulic equipment, with real-time monitoring of verticality.
Quality Inspection: Bearing capacity testing and position verification of completed piles.
Support Installation: Installation of the PV support system on the accepted piles.
Key Features of Precision Driving Technology:
Compared to traditional foundation construction, precision driving has three significant advantages: Fast construction speed, with over a hundred piles installed per day; environmentally friendly, with no noise or vibration pollution; and strong adaptability, maintaining stability under various geological conditions. These characteristics make it an ideal choice for large-scale photovoltaic projects, especially suitable for project types with strict requirements for land disturbance, such as agro-photovoltaic integration.
