Core-pulling type integral girdling-free lossless pile cutting head and construction method thereof
The core-pulling type integral girdling-free lossless pile cutting head comprises a concrete pile, connecting steel bars are pre-buried in the concrete pile, a bayonet socket is mounted at the upper end of the connecting steel bars, a positioning groove is formed in the upper end of the concrete pile, pile steel bars are inserted into the upper side of the bayonet socket, and stable supporting plates are mounted on the lower sides of the multiple pile steel bars; the lower sides of the multiple pile reinforcing steel bars are inserted into the inserting bases at one ends of the connecting reinforcing steel bars through the stable supporting plates, the stable supporting plates are clamped in the positioning grooves, the stable supporting plates and the positioning grooves are connected and fixed through bolts, positioning holes are formed in the stable supporting plates, and the bolts are inserted into the positioning holes. The lower sides of the multiple pile reinforcing steel bars are inserted into the inserting bases at one ends of the connecting reinforcing steel bars through the stable supporting plates, and the stable supporting plates are clamped in the positioning grooves; the stability that the lower ends of the pile steel bars are inserted into one ends of the connecting steel bars is improved, the multiple pile steel bars can be integrally disassembled by disassembling the stable supporting plates, and the pile steel bars are convenient and fast to disassemble and assemble.
本发明公开了一种抽芯式整体免环切无损截桩头及其施工方法，包括混凝土桩，混凝土桩内部预埋有连接钢筋，连接钢筋上端安装有插接座，混凝土桩上端内部开设有定位槽，插接座上侧插设有桩钢筋，且多个桩钢筋下侧安装有稳固支板，稳固支板卡设在定位槽内，且稳固支板和定位槽之间通过螺栓连接固定，稳固支板内部开设有定位孔，且螺栓插设在定位孔，本发明由于多个桩钢筋下侧通过稳固支板插设在连接钢筋一端的插接座内，且稳固支板卡设在定位槽内，有利于提高桩钢筋下端插设在连接钢筋一端的稳定性，而且通过拆卸掉稳固支板，即可整体拆卸多个桩钢筋，使得桩钢筋拆装方便快捷。
