While-drilling pipe pile construction device and method for calcareous sand stratum
The invention relates to the technical field of building construction, in particular to a while-drilling pipe pile construction device and method for a calcareous sand stratum. The drilling machine assembly comprises a tubular pile drilling machine and a pile controller clamp fixedly installed on a preset pile position. A long spiral drill rod is movably hoisted on a power head of the tubular pile drilling machine, a reamer bit is fixedly mounted at the tail end of the long spiral drill rod, the long spiral drill rod extends into an inner cavity of the while-drilling tubular pile, the top of the while-drilling tubular pile is connected with a power head clamp mounted on the power head, and the while-drilling tubular pile is clamped or loosened by the power head clamp; the pile controller clamp is arranged on the periphery of the drilling-following tubular pile in a sleeving mode and used for clamping or loosening the drilling-following tubular pile. The air pressure adjusting assembly comprises a compression pump and a sealing plug matched with an inner cavity of the while-drilling pipe pile, when air pressure is adjusted, the pile controller clamp clamps the while-drilling pipe pile, sealing of the pile side of the while-drilling pipe pile is achieved, the sealing plug is arranged on the top of the while-drilling pipe pile, and the compression pump is connected with a pile side grouting pipe on the pipe wall of the while-drilling pipe pile in a sealed mode.
本发明涉及建筑施工技术领域，尤其涉及一种用于钙质砂地层的随钻跟管桩施工装置及方法。钻机组件包括管桩钻机、以及固定安装在预设桩位上的控桩器夹具；管桩钻机的动力头上活动吊装有长螺旋钻杆，长螺旋钻杆的末端固定安装有扩孔钻头，长螺旋钻杆伸入至随钻跟管桩的内腔，且随钻跟管桩的顶部与动力头上安装的动力头夹具连接，由动力头夹具夹紧或松开随钻跟管桩；控桩器夹具套设在随钻跟管桩外周，用于夹紧或松开随钻跟管桩；气压调节组件包括压气泵、以及与随钻跟管桩内腔相适配的密封塞，当气压调节时，控桩器夹具夹紧随钻跟管桩，实现对随钻跟管桩桩侧的密封，并将密封塞设于随钻跟管桩的顶部，压气泵与随钻跟管桩管壁上的桩侧注浆管密封连接。
