Pile hammer has rapid application in the treatment of soft foundations of high-speed railways and highways, sea reclamation and bridge and dock engineering, deep foundation pit support, and foundation treatment of ordinary buildings. It uses a hydraulic power station as a hydraulic power source, and generates high-frequency vibration through a vibrating box, so that the pile can easily be driven into the soil. It has the advantages of small size, high efficiency and no damage to piles. It is especially suitable for short and medium pile projects such as municipal administration, bridges, cofferdams, and building foundations. The noise is small and meets the city standards.
