施工原理与操作范例:The construction principle and operation example
振动式沉拔桩锤是利用其高频振动，以高加速度振动桩身，将机械产生的垂直振动传给桩体，导致桩周围的土体结构因振动发生变化，强度降低。桩身周围土体液化，减少桩侧与土体的摩擦阻力，然后以挖机下压力、振动沉拔锤与桩身自重将桩沉入土中。拔桩时，在一边振动的情况下，以挖机上提力将桩拔起。打桩机械所需要的激振力要根据场地土层、土质、含水量及桩的种类、构造而综合确定。
Vibrating pile hammer is using its high frequency vibration to vibrate pile body with high acceleration to pass the vertical vibration of mechanical produce to pile which leading to changes in the soil structure around the pile, strength decrease. Soil around the piles become liquefaction to reduce frictional resistance between side of the pile and the soil. Then using the excavator down force, vibrating pile hammer and pile body weight to sink pile into the soil. When extracting piles, in the condition of vibration to pull out the pile by using excavator lift force. Excitation force needed by pile driving machinery are comprehensive determined by site soil, soil condition, moisture content and type of pile, construction.
振动法沉桩效率较其它工法为高，主要适用于钢板桩、钢管桩及长8m以内的细长混凝土预制桩。这种沉桩法最适用于砂土中作业，在黏土中效果较差，必须选用较大功率的机型。
The efficient of vibration pile method is higher than other methods. It is mainly applied to steel sheet pile, steel pipe pile and long slender concrete precast pile within 8 meters. This pile driving method is the most suitable for working in sand and poorer effect in the clay which must select higher power model machines.
