Hole forming construction method for super-long cast-in-place pile in same cast-in-place pile hole in complex stratum
The invention discloses a hole-forming construction method for super-long cast-in-place piles in the same cast-in-place pile hole in a complex stratum. The hole-forming construction method comprises the following steps that S1, a cast-in-place pile-stratum three-dimensional model used for visually displaying the stratum type condition of each cast-in-place pile in the vertical direction is established through three-dimensional modeling software; s2, selecting, processing and manufacturing different drilling equipment according to different stratum types, wherein the drilling equipment comprises a steel casing, a guide frame device, a three-wing drill bit assembly part and a cone hob drill bit assembly part; s3, inserting and driving construction is conducted on the machined and manufactured steel casing; and S4, drilling equipment is adopted for drilling construction of the pile hole of the super-long cast-in-place pile in the complex stratum in the same cast-in-place According to the method, the technical problems that the inclination of the super-long cast-in-place pile has large deviation, the drilling efficiency of the cast-in-place pile is reduced due to the fact that a drill bit is burnt, stuck and buried, the length of the cast-in-place pile is shortened due to the fact that boulders or boulder groups are manually judged as bed rock, and the bearing capacity of a pile body of the cast-in-place pile is reduced can be effectively solved.
本发明公开了一种复杂地层同一灌注桩孔内超长灌注桩成孔施工方法，包括以下步骤：S1：采用三维建模软件建立用于直观显示竖直方向上各灌注桩遇地层类型状况的灌注桩‑地层三维模型；S2：根据不同地层类型选择和加工制作不同钻进设备，包括钢护筒、导向架装置、三翼钻头组装件、牙轮滚刀钻头组装件；S3：对加工制作出的钢护筒进行插打施工；S4：采用钻进设备进行同一灌注桩孔内复杂地层超长灌注桩桩孔钻进施工。本发明方法，能有效地解决超长灌注桩倾斜度出现较大偏差，钻头发生糊钻、卡钻和埋钻而降低灌注桩钻进效率，人为误判孤石或孤石群为基岩而缩短灌注桩桩长、降低灌注桩桩身承载力等质量事故的技术问题。
