Column pile and uplift pile construction method
The invention discloses a stand column pile and uplift pile construction method which comprises the following steps: integrally manufacturing an uplift pile reinforcement cage and a stand column pile, then penetrating through the stand column pile, carrying out pore-forming construction by adopting a rotary drilling rig or a percussion drill, detecting the pore diameter, the pore depth and sediment after pore-forming, and carrying out slurry performance detection and secondary pore cleaning. After the integrally-hoisted stand column pile is installed at the designed position, concrete pouring is conducted, the uplift pile reinforcement cage and the stand column pile are integrally manufactured, factory-like manufacturing can be achieved, and the manufacturing quality of the reinforcement cage and the stand column pile is guaranteed; in a deep and thick rock stratum, the reinforcement cage is square, so that the situation that the reinforcement cage is clamped with a hole wall and falls off is avoided, and the construction quality is guaranteed; the uplift pile reinforcement cage and the stand column pile are integrally manufactured, and the stability in the hoisting process is guaranteed; in a deep and thick rock stratum, the reinforcement cage is square, cage clamping is avoided, the pile diameter does not need to be adjusted under the condition that the design requirement is met, and therefore the construction cost is saved, and the method is worthy of application and popularization.
本发明公开了一种立柱桩兼抗拔桩施工方法，本发明通过抗拔桩钢筋笼与立柱桩整体制作，后穿立柱桩，采用旋挖钻或冲击钻进行成孔施工，成孔后进行孔径、孔深及沉渣检测，并进行泥浆性能检测及二次清孔，将整体吊装立柱桩安装到设计位置后，进行混凝土浇筑，抗拔桩钢筋笼与立柱桩整体制作，能够实现工厂化制作，保证钢筋笼与立柱桩制作质量；在深厚岩层中，钢筋笼呈方形，避免钢筋笼与孔壁出现卡笼情况发生，致使钢筋笼的脱落，保证施工质量；抗拔桩钢筋笼与立柱桩整体制作，保证吊装过程中的稳定性；在深厚岩层中，钢筋笼呈方形，避免出现卡笼情况，在满足设计要求下，不需要调整桩径，从而节约施工成本，值得推广使用。
