The invention discloses a connecting device for burying a pile casing and a construction method. The connecting device comprises a connector connected with a rotary drilling rig, an oil pump cylinderlocated in the pile casing is connected to the lower portion of the connector, a first hydraulic oil pump and a second hydraulic oil pump are arranged at the upper end and the lower end of the oil pump cylinder correspondingly, a first tray moving in the axial direction of the oil pump cylinder is arranged at the bottom of the first hydraulic oil pump, a second tray moving in the axial direction of the oil pump cylinder is arranged at the top of the second hydraulic oil pump, a plurality of mechanical arms arranged in the radial direction of the oil pump cylinder are arranged between the firsttray and the second tray, and supporting plates abutting against the inner wall of the pile casing are arranged at the ends, away from the oil pump cylinder. When the first tray and the second tray move close to each other, the mechanical arms drive the supporting plates to expand in the radial direction, and when the first tray and the second tray move away from each other, the mechanical arms drive the supporting plates to contract in the radial direction.
本发明公开了一种埋放护筒的连接装置及施工方法，包括与旋挖钻机相连的连接头，连接头下方连接有位于护筒内部的油泵筒，油泵筒上下两端分别设置有第一液压油泵和第二液压油泵，第一液压油泵底部设有沿油泵筒轴向移动的第一托盘，第二液压油泵顶部设有沿油泵筒轴向移动的第二托盘，第一托盘和第二托盘之间设有多个沿油泵筒径向设置的机械手臂，机械手臂远离油泵筒的端部设有可与护筒内壁相抵的撑板，当第一托盘和第二托盘相互靠近方向移动时，通过机械手臂带动撑板径向扩张，当第一托盘和第二托盘相互远离方向移动时，通过机械手臂带动撑板径向收缩。
