Cement fly-ash gravel (CFG) pile composite foundation construction process
The invention relates to a cement fly-ash gravel (CFG) pile composite foundation construction process. The process comprises the steps of site excavation; pile point marking; drilling operation; pouring pile forming; and pile top composite treatment, wherein the step of pile point marking comprises the sub-steps that the position of a pile is determined and positioned; and drilling is performed bymeans of a pile point positioning tool, and white ash is poured into a drilled hole so as to mark the pile point position. The CFG pile composite foundation construction process provided by the invention has the effects that the situation that white ash is directly paved and spread on a soil layer and is prone to being washed away by rainwater or a marked pile point fails to be found after soil above a marked pile point is removed, and the pile point position needs to be re-positioned is improved, and the construction efficiency is greatly improved.
本申请涉及一种CFG桩复合地基施工工艺，其包括场地开挖、桩点放位、钻孔操作、灌注成桩和桩顶复合处理的步骤，其中桩点放位包括确定定位桩的位置，用桩点定位工具钻孔并向钻孔中灌注白灰用以标记桩点位置。本申请具有改善直接在土层上铺撒白灰，容易被雨水冲刷掉或者清除掉标记桩点上方的土后找不见标记桩点需要重新定位桩点位置的情况，大大加快了施工效率的效果。
