Based on their power source, photovoltaic piling machines can be divided into diesel piling machines, hydraulic piling machines, and electric piling machines. Diesel piling machines use diesel fuel and are characterized by strong power and a wide range of adaptability, suitable for various geological conditions, but they are noisier and have a certain impact on the environment. Hydraulic piling machines use a hydraulic system for drive, offering advantages such as stable operation, low noise, and high impact force, and are currently the most widely used type. Electric piling machines use electricity, are environmentally friendly and energy-saving, but have relatively lower power, making them suitable for some small-scale photovoltaic projects.
Based on the piling method, photovoltaic piling machines can be further divided into hammer piling machines, vibratory piling machines, and static pressure piling machines. Hammer-driven pile drivers drive piles into the ground through the hammering action of a pile hammer, which is highly efficient but causes greater damage to the pile. Vibratory pile drivers use the vibration generated by a vibrator to liquefy the soil around the pile, thereby reducing the friction between the pile and the soil and making it easier to drive the pile into the ground. They are suitable for softer geological conditions. Static pressure pile drivers, on the other hand, apply static pressure to press the pile into the ground, which has less impact on the surrounding environment and is suitable for applications with high requirements for noise and vibration control.
