机械静力压桩采用静力压桩机将预制桩分节压入地基土层中。静力压桩机有机械式和液压式两种。前者由桩架、卷扬机、加压钢丝绳、滑轮组和活动压梁等部件组成,施压部分在桩顶端面,施加静压力为600～1200 kN。这种桩机设备高大、笨重,行走移动不便,压桩速度较慢,但装配费用较低,少数地区有这种设备的单位还在应用。后者由压拔装置、行
The mechanical static pressure pile uses a static pile driver to press the prefabricated pile section into the foundation soil. There are two types of static pile drivers, mechanical and hydraulic. The former consists of piles, hoists, pressurized steel wire ropes, pulley blocks and moving press beams and other components. The pressure part is on the top of the pile and the static pressure is 600-1200 kN. The pile machine equipment is tall, bulky, inconvenient to move and move, the pile driving speed is slow, but the assembly cost is low, and the unit with such equipment is still in use in a few areas. The latter consists of pressing devices, rows
