施工原理與操作范例:Theconstruction principle and operation example
　　 振動(dòng)式沉拔樁錘是利用其高頻振動(dòng)，以高加速度振動(dòng)樁身，將機(jī)械產(chǎn)生的垂直振動(dòng)傳給樁體，導(dǎo)致樁周圍的土體結(jié)構(gòu)因振動(dòng)發(fā)生變化，強(qiáng)度降低。樁身周圍土體液化，減少樁側(cè)與土體的摩擦阻力，然后以挖機(jī)下壓力、振動(dòng)沉拔錘與樁身自重將樁沉入土中。拔樁時(shí)，在一邊振動(dòng)的情況下，以挖機(jī)上提力將樁拔起。打樁機(jī)械所需要的激振力要根據(jù)場(chǎng)地土層、土質(zhì)、含水量及樁的種類、構(gòu)造而綜合確定。

Vibrating pile hammer is using its high frequency vibration tovibrate pile body with high acceleration to pass the verticalvibration of mechanical produce to pile which leading to changes inthe soil structure around the pile, strength decrease. Soil aroundthe piles become li to reduce frictional resistancebetween side of the pile and the soil. Then using the excavatordown force, vibrating pile hammer and pile body weight to sinkpile into the soil. When extracting piles, in the condition ofvibration to pull out the pile by using excavator lift force.Excitation force needed by pile driving machinery are comprehensivedetermined by site soil, soil condition, moisture content and typeof pile, construction.
　　 振動(dòng)法沉樁效率較其它工法為高，主要適用于鋼板樁、鋼管樁及長(zhǎng)8m以內(nèi)的細(xì)長(zhǎng)混凝土預(yù)制樁。這種沉樁法Zui適用于砂土中作業(yè)，在黏土中效果較差，必須選用較大功率的機(jī)型。

The efficient of vibration pile method is higher than othermethods. It is mainly applied to steel sheet pile, steel pipe pileand long slender concrete precast pile within 8 meters. This piledriving method is the most suitable for working in sand and poorereffect in the clay which must select higher power modelmachines.
