Deboom's hydraulic static pile driver has high effiency and high piling rate with pressing pile300-800meter within 8 hours.It has been a powerful machine to finsih a large-scale foundation project within a short-time. The precast pile entirely depends on the hydraulic static pressure so that the pile can be pressed into the ground steadily and quietly. This unique construction method with nonpollution has gradually taking place of the pile hammering and vibrating. With the development of science and technology and the enhancement of people's consciousness of environment protection, the hydraulic static pile driver has been applied extensively. It'suitable to work under various geological,conditions.such as collapsible loess,silty clay,sand layer.sedimentary geological stratification,fill foundation and so on. This machine is especially suitable working in inner city construction,so it is eligible to be a kind of ideal ecofriendly construction equipment.The most remarkable characters of the hydraulic static pile driver are its high stability of the technical performance and high reliability of its mature technology.
