The invention provides a square pile hole forming construction method which is used for constructing a square pile with the hole forming specification of M * N, n; the method is characterized by comprising the following steps that a round drill bit with the diameter of N is adopted to construct round pile primary hole forming in the position close to one side of a pile hole; the round drill bit with the diameter of N is continuously adopted to construct round pile secondary hole forming in the position close to the other side of the pile hole; stabilizing the hole wall after the two times of hole forming of the circular pile; and constructing M * N square pile holes by adopting a square pile drill bit on the basis of the two times of circular pile hole forming. By means of the method, the problems of low square pile hole forming efficiency and poor hole forming quality can be effectively solved, the cast-in-place pile hole forming efficiency and progress requirements can be guaranteed, and the civilized construction requirements are met.
本发明提供一种方桩成孔施工方法，用于施工成孔规格为M×N的方桩，其中，M>N；其特征在于，包括如下步骤：采用直径为N的圆形钻头靠桩孔的一侧位置施工圆桩一次成孔；继续采用直径为N的圆形钻头靠桩孔的另一侧位置施工圆桩二次成孔；稳定两次圆桩成孔后的孔壁；在所述两次圆桩成孔的基础上采用方桩钻头施工M×N的方桩成孔。利用上述发明能够有效解决方桩孔成孔效率较低和成孔质量的问题，既能保证灌注桩成孔效率和进度要求，又满足文明施工要求。
