Method for constructing cast-in-situ bored pile by rotary drilling
The invention provides a construction method for drilling a cast-in-place pile by a rotary drilling rig, and belongs to the technical field of cast-in-place pile construction, which comprises the following steps of: measuring and setting out, excavating a pile casing to embed a foundation pit, sinking a steel pile casing, backfilling clay around the pile casing, placing a drilling rig in place, forming a hole by the drilling rig, cleaning the hole for the first time and detecting, manufacturing a reinforcement cage and putting the reinforcement cage down, installing a guide pipe, cleaning the hole for the second time, pouring underwater concrete, breaking a pile head and detecting the pile. And finishing construction. The side edge of the sleeve is blocked by arranging slurry, collapse caused by quicksand is avoided, meanwhile, holes are cleaned twice, so that the quality of a cast pile is better guaranteed, meanwhile, the construction efficiency is high, the construction period is short, a reinforcement cage is arranged in advance, construction of the construction period is not affected, time is saved, meanwhile, the welding quality is guaranteed, and the overall construction quality is improved.
本发明提供旋挖钻钻孔灌注桩施工方法，属于灌注桩施工技术领域，测量放样，开挖护筒埋设基坑，钢护筒沉放，护筒周边粘土回填处理，钻机就位，钻机成孔，一次清孔并检测，制作钢筋笼并下钢筋笼，安装导管，二次清孔，浇筑水下砼，破桩头和检桩，完成施工。本发明通过设置泥浆进行对套筒的侧边进行封堵，避免流沙造成坍塌，同时两次对孔进行清理，从而更好的保证浇筑桩的质量，同时施工效率高，工期快，钢筋笼提前设置，不影响工期的施工，节省时间同时保证焊接的质量，提高施工整体质量。
