Cast-in-situ bored pile construction method capable of avoiding empty pile backfilling
The invention relates to the technical field of civil engineering, and discloses a cast-in-situ bored pile construction method capable of avoiding empty pile backfill, which comprises the following steps of: welding a circular baffle with the diameter greater than that of a cylindrical steel casing at an opening at the upper end of the cylindrical steel casing by utilizing the existing cylindrical steel casing during drilling and hole forming; the circular baffle blocks the opening of the pile hole through self weight, the purpose of sealing the pile hole can be achieved, an empty pile does not need to be backfilled, in the earth cutting process, the cylindrical steel casing and the circular baffle seal the pile hole in real time through the self weight, and therefore investment is reduced, field work efficiency is improved, and material waste is reduced. The effects of saving social resources, improving the social production efficiency, reducing the cost of a construction unit and improving the working efficiency of the construction unit are achieved.
本发明涉及土木工程技术领域，公开了一种避免空桩回填的钻孔灌注桩施工方法，本发明对桩孔的封堵方法是利用钻进成孔时已有的圆柱钢护筒，在圆柱钢护筒的上端开口焊接直径大于圆柱钢护筒直径的圆形挡板，圆形挡板利用自重封堵于桩孔的开口，可达到对桩孔封口的目的，不需要再对空桩进行回填，并且进行挖土的过程中，圆柱钢护筒和圆形挡板利用自重以实时对桩孔封口，从而降低了投资，提高了现场工作效率，减少了材料浪费，达到可节约社会资源、提高社会生产效率、降低建设单位成本，以及提高施工单位工作效率的效果。
