本实施例中，桩顶顶推定位装置100的结构见专利号“201510853400.1”公开的一种桩顶顶推定位装置，结合图3、图4所示，包括桩顶定位座101、升降调节装置102、支撑锁紧装置103(即包括支撑架、摇臂卡板及锁紧装置)及三向千斤顶104。桩顶定位座101安装于钢护筒600桩顶并与钢护筒600起限位和承载作用；升降调节装置102的下部与桩顶定位座101相连，升降调节装置102的上部与支撑锁紧装置103相连，使得支撑锁紧装置103顶面的标高由升降调节装置102调整；三向千斤顶104置于支撑锁紧装置103上，三向千斤顶104实现纵移、竖向顶升及横向纠偏，具体结构请参见公开文献；承载平台200支撑在支撑锁紧装置103两侧摇臂顶面，承载平台200前移时，将摇臂卡板106拆除，三向千斤顶104顶升承载平台200脱离支撑锁紧装置103的摇臂后前移，发生偏移时，三向千斤顶104推动承载平台200横向纠偏。
如图5所示，承载平台200包括多根平行布置的主纵梁201、与主纵梁201垂直布置的多根横梁202及分布在主纵梁201外侧的悬臂梁203，悬臂梁203固定在横梁202的端部；主纵梁201按钢护筒600间距沿纵向布置，其跨度不小于两根钢护筒600，横梁202按起重设备所需工作区域横向布置， 悬臂梁203按辅助设备所需空间布置在最边上主纵梁201的外侧。同时，操作平台500挂在主纵梁201的两侧，满足人员到达桩顶顶推定位装置100和运输可调连杆机构105的空间需要。
作业平台300布置于承载平台200上，其作业平台300的空间不仅要满足导向架400的安装及前轮钢护筒600的打桩施工，还要满足后轮钢护筒600的钻孔及钢筋笼下放、模板吊装等钻孔桩的施工。
导向架400与桩位位置对应布置，以覆盖作业平台300前部整轮钢护筒600施工作业面，导向架400的结构见专利号“201510856316.5”公开的一种桩顶支撑步履式移动打桩平台中的大轮架导向架，结合图6所示，包括大轮架导向架体403、大轮架导向轨道401及设置在大轮架导向轨道401上的滑块402，大轮架导向架体403可沿大轮架导向轨道401移动和定位，大轮架导向架体401的开合适应钢护筒600施打时的喂桩。
另外，本实施例中两两相邻的桩顶顶推定位装置100的桩顶定位座101之间通过可调连杆机构105相连，长度可调的可调连杆机构105采用的是双向调节丝杆，使所有已安装的桩顶顶推定位装置100连成一体。

2)利用作业平台300上的履带吊700和导向架400施打N+1钢护筒600，同时，利用作业平台300上的旋挖钻机800完成第一轮钢护筒600的钻孔施工，N+1轮钢护筒600施打完成后，履带吊700行走至作业平台300的中部，利用履带吊700对已完成钻孔施工的第一轮钢护筒600完成钻孔桩的施工；
3)第一轮钢护筒600完成钻孔桩的施工，在对应主纵梁201的已施打完成的N+1轮每个钢护筒600桩顶上均安装桩顶顶推定位装置100，桩顶顶推 定位装置100的三向千斤顶104将承载平台200顶起脱离支撑锁紧装置103的摇臂并推动整个施工平台水平前移至N+1轮钢护筒600，三向千斤顶104下降，将施工平台锁定在第三轮钢护筒600至N+1轮钢护筒600的支撑锁紧装置103的摇臂上，并用摇臂卡板106上并锁定，发生偏移时，三向千斤顶104可推动整个施工平台进行横向纠偏，平台顶推到位后，借助操作平台500拆除第二轮每个钢护筒600上的桩顶顶推定位装置100，；
4)施工平台同步移动到位后，然后重复步骤2)，利用作业平台300上的履带吊700和导向架400施打N+2轮钢护筒600，同时，利用作业平台300上的旋挖钻机800完成第二轮钢护筒600的钻孔施工，N+2钢护筒600施打完成后，利用履带吊700对已完成钻孔施工的第二轮钢护筒600完成钻孔桩的施工；
5)然后重复步骤3)，在对应主纵梁201的已施打完成的N+2轮每个钢护筒600桩顶上安装从第二轮钢护筒拆下的桩顶顶推定位装置100，桩顶顶推定位装置100的三向千斤顶104将承载平台200顶起脱离桩顶顶推定位装置100的支撑锁紧装置103的摇臂并推动整个施工平台水平前移至N+2轮钢护筒600，将施工平台锁定在第四轮钢护筒600至N+2轮钢护筒600的桩顶顶推定位装置100上，借助操作平台500拆除第三轮每个钢护筒600上的桩顶顶推定位装置100；继续重复步骤2)和步骤3)直至完成所有的钻孔桩施工。
