Soil plug cleaning method for open steel pipe pile
The invention discloses a soil plug cleaning method for an open steel pipe pile. The technological process comprises the steps of taking position of a drilling machine, calibration and fixing, drill rod running, pipe filling with water, high-pressure gas lifting (drilling) hole (soil plug) cleaning, slurry cleaning and water pumping and draining. The high-pressure gas lifting reverse circulation hole cleaning method has the advantages of being high in slag cleaning speed, thorough and clean in cleaning and small in slurry discharge amount, and meanwhile, pollution to the environment can be reduced, the construction treatment cost is reduced, and the method is easily implemented.
本发明公开了一种敞口钢管桩土塞清理方法，其工艺流程为钻机就位、校准、固定→下钻杆→管内充水→高压气举（钻进）清孔（土塞）→泥浆清理→抽排水。本发明高压气举反循环清孔法具有清渣速度快、清理彻底干净、泥浆排放量少的特点，同时还可减少对环境的污染，降低施工处理成本，易于实现。
