螺旋打桩机桩架首要由顶部滑轮组、立柱、斜撑杆、底盘、行走组织、反转组织、卷扬组织、室、液压及电气组成。立柱为折叠式，采用箱形截面结构型式，法兰衔接。立柱两边配有圆形或方形滑道作为动力头、钻杆上下运动的导向和抗扭。此种钻机装备的箱形可折叠式立柱使用液压缸进行起降，方便快捷，运送时也不需拆卸。立柱下部与上盘铰接，中后部与斜撑杆铰接，立柱顶部有滑轮组，用来完成对动力头、钢筋笼和注浆导管等的起降。动力头可沿滑道上下邮寄时可拆卸。
the pile frame of the screw piling machine is mainly composed of the top pulley group, the column, the inclined pole, the chassis, the walking organization, the reverse organization, the hoist organization, the room, the hydraulic and electrical. the column is foldable, with box section structure and flange connection. both sides of the column are equipped with circular or square slideway as the power head, drill pipe up and down movement guidance and torsion. the box shaped foldable column of this drilling rig is equipped with hydraulic cylinders for take-off and landing, which is convenient and quick, and does not need to be disassembled during transportation. the lower part of the column is articulated with the upper plate, the middle and the rear are articulated with the inclined pole, and the top of the column has a pulley group, which is used to complete the take-off and landing of the power head, the reinforcement cage and the grouting pipe. the power head can be dismantled when mailing up and down the slideway.
施工原理
construction principle
振荡式沉拔桩锤是使用其高频振荡，以高加速度振荡桩身，将机械发生的笔直振荡传给桩体，导致桩周围的土体结构因振荡发生变化，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、振荡沉拔锤与桩身自重将桩沉入土中。拔桩时，在一边振荡的情况下，以挖机上提力将桩拔起。打桩机械所需求的激振力要根据场所土层、土质、含水量及桩的种类、结构而归纳断定。
the oscillating pile hammer is using its high frequency oscillation to oscillate the pile with high acceleration, and transfer the mechanical oscillation to the pile body, which leads to the change of the soil structure around the pile and the decrease of the strength. the soil around the pile is liquefied to reduce the frictional resistance between the pile side and the soil, and then the pile is sunk into the soil by the lower pressure of the excavator, the vibration sinking hammer and the self weight of the pile body. when the pile is pulled out, the pile is pulled up by lifting force on the side when the side oscillates. the exciting force required by piling machinery should be concluded according to the soil layer, soil quality, water content and pile type and structure.
振荡法沉桩功率较其它工法为高，首要适用于钢板桩、钢管桩及长8m以内的细长混凝土预制桩。这种沉桩法适用于砂土中作业，在黏土中效果较差，有必要选用较大功率的机型。
the power of pile driving by oscillating method is higher than that of other methods. it is mainly suitable for steel sheet piles, steel pipe piles and slender concrete precast piles within 8m length. this kind of pile driving method is suitable for sand soil operation, and the effect is poor in clay. it is necessary to choose a larger power type.
