Secondary hole cleaning construction method for pile foundation
The invention discloses a secondary hole cleaning construction method for a pile foundation, and relates to the technical field of building construction. The method comprises the specific steps of preparation work, hole center positioning, drilling machine positioning, drilling construction, steel reinforcement cage manufacturing and placing, and secondary hole cleaning and sweeping for the pile foundation. A reverse circulation drilling machine slag discharging system is adopted, the power of the system is high, holes can be quickly cleaned, time is saved, hole cleaning quality is guaranteedduring deep pile construction, hole collapse is prevented, therefore, the construction period is saved, meanwhile, the ecological environment is protected, safe and civilized construction management is facilitated, and economy and environmental protection are facilitated.
本发明公开了一种桩基二次清孔施工方法，涉及建筑施工技术领域，具体步骤包括准备工作、孔心定位、钻机就位、钻孔施工、钢筋笼制作与安放、桩基二次清孔和清扫整理。本发明采用反循环钻机排渣系统，该系统功率大，可快速清孔，节约时间，在深桩施工时保证清孔质量，防止塌孔，从而达到节省工期的同时，保护生态环境，有助于安全文明施工管理，利于经济环保。
