Treatment method for waste super-long stiff composite pile
The treatment method comprises the following steps: positioning a waste pile to be pulled out, arranging a PHC pipe pile on soil around the pile through cemented soil, and positioning an interface between the cemented soil and the soil around the pile; symmetrical hole guiding is conducted on the interface through a down-the-hole hammer, and symmetrical hole sets are drilled in the interface; using a thin PVC pipe to rotate along with the pipe at the position of the symmetrical hole group; the waste pile is lifted and pulled, and the thin-skin PVC pipe is removed; the pulled-out stiff composite pile hole is backfilled with river sand, and preparation is made for follow-up pile planting. According to the treatment method for the waste super-long stiff composite pile, the technical problem that in the prior art, a high-strength concrete pipe pile is difficult to repair is solved.
本发明公开了一种超长劲性复合桩废桩的处理方法，包括步骤为将待拔废桩定位，PHC管桩通过水泥土设置在桩周土上，定位水泥土与桩周土的交界面；通过潜孔锤对交界面对称引孔，在交界面上钻出对称孔组；使用薄皮PVC管在对称孔组的位置进行跟管转进；吊拔废桩，清除薄皮PVC管；拔出后的劲性复合桩孔采用河沙回填，为后续植桩做准备。本发明通过超长劲性复合桩废桩的处理方法解决了现有技术中的高强混凝土管桩难以修复的技术问题。
