Pile drivers are primarily installed on excavators, which include both land-based excavators and amphibious excavators. Excavator-mounted pile drivers are mainly used for pile driving, with pile types including pipe piles, steel sheet piles, steel pipe piles, precast concrete piles, wooden piles, and photovoltaic piles driven into water. They are particularly suitable for medium to short pile projects in municipal, bridge, cofferdam, and building foundation construction. They have low noise levels, meeting urban standards.
Compared to traditional pile drivers, hydraulic vibratory pile drivers have greater impact energy and higher pile driving efficiency. Hydraulic vibratory pile drivers utilize their high-frequency vibration to vibrate the pile body with high acceleration, transferring the vertical vibration generated by the machine to the pile, causing changes in the surrounding soil structure and reducing its strength. The soil around the pile liquefies, reducing the frictional resistance between the pile and the soil, and then the pile is driven into the ground using the downward pressure of the excavator, the vibration of the pile driving hammer, and the weight of the pile itself. When extracting the pile, the pile is lifted using the lifting force of the excavator while vibrating on one side. The required excitation force for the pile driving machinery is comprehensively determined based on the site’s soil layers, soil quality, moisture content, and the type and structure of the pile.
Product Features of Hydraulic Vibratory Pile Driver:
1. High efficiency: The vibration sinking and pulling speed is generally 4-7 meters per minute, reaching up to 12 meters per minute (in non-silty soils), which is much faster than other pile driving machinery. It has an efficiency 40%-100% higher than pneumatic hammers and diesel hammers.
2. Wide range: Except for rock formations, the high-frequency hydraulic pile driver is suitable for construction in any harsh geological conditions, easily penetrating through gravel layers and sandy layers.
3. Versatile functions: In addition to constructing various load-bearing piles, the high-frequency hydraulic pile driver can also be used for building thin-wall impermeable walls, deep compaction treatments, and ground compaction treatments.
4. Environmentally friendly: The hydraulic pile driver has minimal vibration and low noise during operation. With the addition of a noise-reducing power box, it fully meets environmental requirements when used for construction in urban areas.
5. Wide applicability: It is suitable for driving piles of any shape and material, such as steel pipe piles and concrete pipe piles. It can be used in any soil layer, for pile driving, pile extraction, and underwater pile driving. It can also be used for pile rack operations and hanging operations.
The energy transmission efficiency of hydraulic vibratory pile drivers can reach 70% to 95%, ensuring accurate pile control and enabling pile driving operations in different geological conditions. Hydraulic vibratory pile drivers have been quickly applied in various fields such as high-speed railways, soft ground treatment for highways, land reclamation and bridge construction, port engineering, deep foundation pit support, and foundation treatment for ordinary buildings. With superior performance, these machines use hydraulic power stations as hydraulic power sources and generate high-frequency vibrations through vibration boxes, making it easy to drive piles into the soil layer. They have advantages such as low noise, high efficiency, and no damage to the piles. Hydraulic pile drivers perform well in reducing noise, vibration, and noise, making them particularly suitable for urban construction needs.
