Rotary excavating cast-in-place pile drill-burying and rod-burying treatment method
The invention relates to a rotary excavating cast-in-place pile drill-burying rod-burying treatment method. The rotary excavating cast-in-place pile drill-burying rod-burying treatment method comprises the following steps that firstly, a long pile casing is buried close to a pile casing of an original rotary excavating hole drill-burying rod-burying position by using a rotary excavating machine, drilling is carried out by using a cutting pick slag fishing hopper, the angle of a drill rod is adjusted while drilling is carried out to enable a drill bit to deviate into an original rotary excavating hole until the drill bit touches the buried drill rod, then the angle of the drill rod is adjusted to drill downwards to the depth below the drill-burying rod-burying position to form an auxiliary hole, an obstacle is fished out in cooperation with a mechanical lock rod, and the mechanical lock rod is pulled out; then, low-grade concrete is adopted for backfilling the auxiliary hole and the original rotary excavating hole, the concrete in the auxiliary hole spreads into the original rotary excavating hole or other auxiliary holes in the pouring process, finally, the concrete is poured to the shallow ground, and pile casings of the auxiliary hole and the original rotary excavating hole are pulled out; and finally, the pile position is subjected to point releasing again, the long pile casing is buried again, a cutting pick slag fishing bucket is used for drilling to the buried drill rod, then a specially-made sleeve drill is replaced, the falling drill bit is firmly sleeved and taken out, and finally another drill bit is replaced to continue the hole forming operation.
本发明涉及一种旋挖灌注桩埋钻埋杆处理方法，首先，利用旋挖机在原旋挖孔埋钻埋杆位置紧挨其护筒另行埋入长护筒，使用截齿捞渣斗进行钻进，边钻进边调整钻杆角度使钻头偏入原旋挖孔内，直到钻头碰到被埋的钻杆，再调整钻杆角度向下钻至埋钻埋杆位置以下深度形成辅助孔，与机锁杆配合捞出障碍物并拔出机锁杆；然后，采用低标号混凝土对辅助孔及原旋挖孔进行回填，浇筑过程中辅助孔内混凝土蔓延至原旋挖孔或其他辅助孔内，最终浇筑至浅层地面处，并拔出辅助孔及原旋挖孔的护筒；最后，重新对桩位进行放点，埋设长护筒，使用截齿捞渣斗钻至埋钻埋杆处，随后换上特制套钻，将掉落的钻头套牢并取出，最后再换上另一个钻头继续进行成孔作业。
