Gobi desert micropore cast-in-place pile hole and micropore cast-in-place pile construction method
The invention belongs to the technical field of pile foundation hole construction, and particularly relates to a gobi desert micropore cast-in-place pile hole and a micropore cast-in-place pile construction method. The gobi desert micropore cast-in-place pile hole construction method comprises the steps that A1, a site is leveled, and the positions of pile holes are marked after the positions of the pile holes are determined through surveying and setting out; a2, the spiral drilling machine is in place, and a spiral drilling rod on the spiral drilling machine is aligned with the pile hole marking position for dry operation hole guiding to form an initial hole; a3, the initial hole is filled with water; and A4, the percussion drill is in place, and a percussion bit is aligned with the center of the initial hole for percussion hole forming. The pile hole construction is completed in the mode that the spiral drill rod is adopted for conducting dry operation to lead the hole to form the initial hole, then the percussion drill is adopted for extruding and compacting soil on the hole wall, a protection wall is formed in the pile hole, the hole forming quality is guaranteed, and the pile hole construction efficiency is improved. According to the micropore cast-in-place pile construction method, the pile hole construction method is adopted for forming holes, soil around the pile holes is compact and free of topsoil, embedded parts can be placed for pouring without cleaning the holes, the workload is reduced, and the construction efficiency is improved.
本发明属于桩基孔施工技术领域，具体涉及一种戈壁滩微孔灌注桩桩孔以及微孔灌注桩施工方法。戈壁滩微孔灌注桩桩孔施工方法包括：A1、平整场地，测量放线确定桩孔位置后标记桩孔位置；A2、螺旋钻机就位，螺旋钻机上的螺旋钻杆对准桩孔标记位置干作业引孔形成初始孔；A3、将初始孔注满水；A4、冲击钻机就位，冲击钻头对准初始孔的中心冲击成孔。通过先采用螺旋钻杆干作业引孔形成初始孔、再采用冲击钻将孔壁土质挤压密实的方式完成桩孔施工，桩孔内形成护壁，保证成孔质量，提高桩孔施工效率。微孔灌注桩施工方法采用上述桩孔施工方法成孔，桩孔周围土体密实无浮土，无需清孔即可放置预埋件进行浇筑，减少作业量，提高施工效率。
