Soft soil section rectangular anti-slide pile forming method
The invention discloses a pile forming method for a rectangular anti-slide pile in a soft soil section. The pile forming method mainly comprises the steps of construction preparation, measurement positioning, arrangement of a reinforced concrete lock catch at a hole opening, drilling machine in-place, hole position correction, impact hole forming, slurry circulation, hole cleaning and slurry replacement, final hole acceptance inspection, lowering of a square reinforcement cage and a guide pipe, secondary hole cleaning and concrete pouring for pile forming. According to the pile forming method, on the basis of traditional percussion drill hole forming, an orifice hole protecting structure and a percussion drill bit are improved. The rectangular anti-slide pile construction method is improved on the basis of a conventional percussion drill, is convenient, safe and reliable in soft soil section construction, has the advantages of being high in operation efficiency, low in cost, safe, reliable and small in influence of underground water, and has wide application prospects.
本发明公开了一种软土地段矩形抗滑桩成桩方法，主要包括施工准备、测量定位、孔口设置钢筋混凝土锁扣、钻机就位、孔位校正、冲击成孔、泥浆循环、清孔换浆、终孔验收、下方形钢筋笼与导管、二次清孔和灌注混凝土成桩几个步骤。该成桩方法在传统的冲击钻成孔的基础上，对孔口护孔结构与冲击钻头进行了改进。本发明在常规冲击钻的基础上进行改进，提出了一种软土地段施工便捷，安全可靠的矩形抗滑桩方法，具有作业效率高，成本低，安全可靠，受地下水影响小的特点，具有广泛的应用前景。
