摘要
结合佛山市高明君御海城国际酒店工程钻孔灌注桩施工,详细介绍了深层大倾斜岩面的处理原理,总结了钻孔灌注桩施工方法,包括工艺流程,即发现偏孔,测量孔底倾斜岩面高低端的位置,钻引爆孔,爆破,抛填块石和黏土,重新校核钻机及纠偏钻孔,清孔,钢筋笼制作安放,水下混凝土浇筑;最后介绍了成桩检测内容。
Based on bored pile construction of Gaomingjun Yuhaicheng International Hotel engineering in Foshan, the author introduces treatment principle of deep and large inclined rock surface, summarizes construction method of bored pile. The construction process is finding deflection hole, measuring the position of high and low end of inclined rock surface at the bottom of hole, drilling detonation hole, blasting, throwing and filling rubble and clay, anew checking drilling rig and rectification for drilling hole, hole cleaning, making and setting reinforcement cage and underwater concrete pouring. Finally, the author introduces pile inspection.
