Method for processing empty hole section of long spiral cast-in-place pile
The invention provides a long spiral cast-in-place pile empty hole section treatment method which comprises the following steps: driving a steel casing, drilling and carrying out pressure grouting; lifting out the drilling tool and the soil to form an empty hole section; digging out the soil on the concrete surface by machinery; mounting a reinforcement cage; backfilling empty hole sections; according to the processing method for the empty hole section of the long spiral cast-in-place pile, concrete of the empty hole section can be saved, the work of chiseling away an ultrahigh pile head can be basically omitted, construction waste is reduced, consumption of resources and energy is reduced in the aspects of materials and procedures, the effects of energy conservation and emission reduction are achieved, and the engineering cost is greatly reduced.
本发明提供一种长螺旋灌注桩空孔段处理方法，包括如下步骤，打入钢护筒，钻进，压灌；提出钻具及土，形成空孔段；换机械进行砼面掏土；钢筋笼安装；空孔段回填；该长螺旋灌注桩空孔段处理方法，不但能够节省空孔段混凝土，还能够基本免去凿除超高桩头的工作，减少建筑垃圾，从材料和工序上减少资源和能源的消耗，达到节能减排的效果，并且大幅降低工程成本。
