CFG pile long auger drilling core tube pumping mixture pouring pile forming construction method
The invention discloses a CFG pile long auger drilling core tube pumping mixture pouring pile forming construction method. The CFG pile long auger drilling core tube pumping mixture pouring pile forming construction method comprises the following steps of determining soil characteristics of a construction site, selecting a pile position determining method according to the soil characteristics, determining technological parameters of CFG pile construction, processing the earth surface, setting a working cushion layer, measuring and setting out a pile position, placing a drilling machine in place, starting drilling, drilling a long spiral drilling core tube to a preset depth, stopping drilling by the drilling machine, pumping a pouring mixture to the long spiral drilling core tube, starting the drilling machine to lift the drill, and moving the long spiral drilling core tube out of a drill hole; moving the drilling machine to a next pile position which is determined. According to the method, in railway construction, pouring of a CFG pile is achieved according to the soil texture characteristics, one-time forming of the CFG pile is achieved, rapid construction of the CFG pile under different soil textures can be achieved, the construction time and the construction cost can be effectively saved, pollution to the environment is reduced, and environment improvement is facilitated.
本发明公开了一种CFG桩长螺旋钻孔芯管泵送混合料灌注成桩施工方法，包括以下步骤：确定施工现场的土质特征，并根据土质特征选择桩位确定方法，确定CFG桩施工的工艺参数，地表处理，并设置工作垫层，桩位测量放样，钻机就位，钻孔开始，将长螺旋钻孔芯管钻入至预定深度，钻机停止钻进，并泵送灌注混合料至长螺旋钻孔芯管，钻机启动提钻，将长螺旋钻孔芯管移出钻孔；移动钻机至已确定的下一桩位，本发明通过在铁路修建中，根据土壤土质特征实现对CFG桩的浇筑，实现对CFG桩的一次成型，可以实现不同土质下CFG桩的快速施工，能够有效的节省施工时间与施工成本，减小了对环境的污染，有利于改善环境。
