拔桩机利用振动、静力或锤击作用将桩拔出地层的桩工机械。拔桩作业常采用相应的振动沉桩机、静力压桩机或双动汽锤,再配以桩架和索具,故也称振动沉拔桩机、静力压拔桩机。桩工施工中以振动拔桩较普遍,作业时,将振动拔桩机固装于桩头，通过弹簧吸振器和索具悬挂于吊钩下，开动拔桩机，振动器产生的振动，引起桩和土体共振，土体结构破坏，桩身与土体间摩擦力减小，同时收紧索具,将桩逐渐拔出。若采用偏心块式振动器,因沉桩和拔桩阻力方向不同，必须对偏心块进行调整。此种拔桩设备结构简单，拔桩效率高，有发展前途。液压拔桩机利用其夹桩器夹住桩头，液压缸强制顶压夹桩器，使之向上顶升一段距离,将桩逐段拔出,适用在粘土、砂土或含少量砾石的土层中拔工字钢或型钢桩。也有采用机械方法拔桩的，即由电动机驱动卷扬机，利用钢丝绳滑轮组的拉力将桩强制拉出地面。使用方便,成本低,但拔桩力不大、设备笨重、拔桩效率低，只适用于软土地层施工。利用双动汽锤拔桩，系将锤体倒置，固定于桩头，并悬挂于索具下，先将土中桩头晃动，减低桩和土壤间紧密度，然后开动汽锤，向上锤击振动，收紧索具，将桩逐渐拔出，可在各种土层中拔混凝土桩及其他桩。
