Foundation reinforcing method with staggered CFG piles
The invention discloses a method for reinforcing a foundation with staggered CFG (cement fly-ash gravel) piles, which comprises the following steps of: during CFG construction, leveling and compacting the original ground until the original ground is kept in a stable state during pile foundation construction, then measuring and setting out, placing a drilling machine in place, drilling to form a hole, pumping a mixture, shifting the drilling machine, cleaning soil between the piles, cutting off pile heads, and detecting the formed piles, low-strain pile body integrity detection, single-pile vertical bearing capacity inspection, inter-pile soil backfilling and mattress layer construction are carried out. According to the CFG pile dislocation foundation reinforcement measure designed by the invention, in the pile forming detection step, if displacement of adjacent piles in the horizontal direction is found in the pile forming detection process, the foundation reinforcement method needs to be carried out on the basis that the positions of the piles are not changed.
本发明公开了一种CFG桩发生错位的地基加固方法，CFG施工时对原地面进行整平并压实到桩基施工中保持的平稳状态，之后进行测量放样，钻机就位、钻进成孔、泵送混合料、钻机移位并清理桩间土、切除桩头、进行成桩检测：符合地基平板，静载荷实验，低应变桩身完整性检测，单桩竖向承载力检验、桩间土回填、褥垫层施工。本发明设计的CFG桩错位的地基加固措施在成桩检测的步骤上，如果成桩检测的过程中发现相邻桩水平方向发生了位移，在不改变桩位置的基础上，需要进行的地基加固方法。
