Working Principle of Photovoltaic Pile Driver and Its Application in Photovoltaic Power Station Construction
Working principle of photovoltaic pile driver and its application in photovoltaic power station construction
With the rapid development of the global new energy industry, the scale of photovoltaic power plant construction continues to expand. As the core equipment for the construction of photovoltaic bracket foundations, photovoltaic pile drivers play a crucial role in the entire project construction process. The photovoltaic pile driver uses efficient and precise pile planting methods to firmly implant the photovoltaic support foundation piles underground, providing reliable guarantees for the long-term safe operation of photovoltaic modules.
What is a photovoltaic pile driver
Photovoltaic pile driver is a specialized engineering machinery equipment used for the construction of photovoltaic power stations. It is mainly used to efficiently implant foundation piles such as steel pipe piles, H-shaped steel piles, and spiral piles underground. Compared with traditional manual or ordinary pile driving equipment, photovoltaic pile drivers have the advantages of high efficiency, high precision, strong adaptability, and low construction costs, and are indispensable construction equipment for modern photovoltaic projects.
The core working principle of photovoltaic pile driver
The essential working principle of photovoltaic pile driver is to output energy through mechanical power and hydraulic system, reduce soil resistance according to different geological conditions, and enable the pile to smoothly enter the underground. According to the different planting methods and force forms, the mainstream photovoltaic pile drivers in the photovoltaic industry are mainly divided into three types: vibration type, spiral type, and hydraulic hammer type.
Mainstream photovoltaic pile driver types and principle analysis
1、 Vibration type photovoltaic pile driver (most widely used)
The vibration type photovoltaic pile driver is currently the most widely used model in the construction of photovoltaic power stations, especially suitable for soft soil geology such as plains and hills.
Working Principle:
The equipment is powered by a diesel engine or motor to drive the hydraulic system, which further drives the vibrating hammer to produce high-frequency vertical vibration. The vibration is transmitted downwards along the pile to the surrounding soil layer, causing the soil to be disturbed and softened in a short period of time, effectively reducing the frictional resistance between the pile and the soil. Under the combined action of equipment weight and hydraulic downforce, the pile is quickly and smoothly pressed into the ground. After stopping the vibration, the soil is compacted again to form stable support.
Applicable scenarios:
Large scale photovoltaic power station projects in soft soil layers such as clay, silt, sand, and fine gravel layers.
2、 Spiral photovoltaic pile driver (suitable for spiral piles)
Spiral photovoltaic pile drivers are mainly used for installing spiral piles, emphasizing construction accuracy and surface protection.
Working Principle:
Driven by a hydraulic motor, the power head drives the spiral pile to rotate. The spiral blades cut the soil during rotation and discharge the soil debris from the ground, achieving synchronous completion of drilling and pile planting. By using a depth and verticality monitoring system, ensure that the pile is accurately installed at the design position.
Applicable scenarios:
Farmland, grassland, sandy land, as well as photovoltaic projects with high environmental impact requirements such as "agricultural photovoltaic complementarity" and "fishery photovoltaic complementarity".
3、 Hydraulic hammer type photovoltaic pile driver (suitable for complex geology)
The hydraulic hammer type photovoltaic pile driver is mainly used in construction environments with hard geological conditions or containing pebbles and weathered rocks.
Working Principle:
The hydraulic system drives the heavy impact hammer to repeatedly lift and fall, gradually driving the pile into the ground through high-energy impact. The impact frequency and energy can be adjusted according to the geological conditions, and combined with a verticality monitoring system to ensure stable penetration of the pile.
Applicable scenarios:
Mountain photovoltaic, desert photovoltaic, and engineering sites with hard clay and pebble layers.
The key auxiliary system of photovoltaic pile driver
Crawler walking system
The tracked chassis can effectively increase the grounding area, reduce the pressure on the ground, and keep the photovoltaic pile driver stable during construction on soft or sloping ground.
Intelligent Control and Positioning System
Some high-end photovoltaic pile drivers are equipped with GPS, tilt angle sensors, and depth detection devices, which can monitor the pile position, verticality, and implantation depth in real time, improving construction accuracy.
Overview of Manufacturing and Application Process of Photovoltaic Pile Driver
During the manufacturing process, photovoltaic pile drivers typically use high-strength steel structures and high-quality hydraulic components to ensure stable operation under long-term vibration and impact conditions. Strict debugging and performance testing are required before leaving the factory.
In actual construction, equipment can quickly enter the site, accurately locate, achieve continuous and efficient pile planting, and significantly shorten the construction period of photovoltaic power plants.
