Cast-in-situ bored pile structure and construction technology

The invention relates to the field of construction, in particular to a cast-in-situ bored pile structure and a construction technology.The cast-in-situ bored pile structure comprises a stabilizing table, the stabilizing table is provided with a mounting through groove allowing a pile casing to penetrate through, and at least two sliding bases are arranged on the stabilizing table in a sliding mode; the stabilizing table is provided with a sliding driving piece used for controlling the sliding bases to slide in the direction close to each other or away from each other, the sliding bases are provided with clamping ring plates used for clamping the pile casing, and the clamping ring plates are rotationally provided with at least two clamping wheels abutting against the pile casing. The two clamping wheels are distributed in the height direction of the pile casing. The method has the effect of reducing the influence of rammed earth construction on the position of the sheath. 本申请涉及施工的领域，尤其是涉及一种钻孔灌注桩结构及施工工艺，其包括稳定台，
