Collapsible loess geology static pressure compaction pile construction method
The invention discloses a static pressure compaction pile construction method for collapsible loess geology, which adopts a plain soil compaction pile to treat a foundation, and performs static pressure compaction pile construction through original ground treatment, measurement positioning, static pressure pore forming, pore forming inspection, filler moisture content test, plain soil layered ramming and filling, comprehensive inspection and pile forming. The static pressure compaction pile construction problem of the collapsible loess geology is effectively solved, the construction is safe, the quality is reliable, the progress is fast, the input cost is low, and compared with traditional compaction pile construction methods such as hammering immersed tube hole forming, vibrating immersed tube hole forming and impact hole forming, the static pressure hole forming cost is high, and the construction efficiency is high. However, compared with a CFG pile and a prefabricated square pile with the same foundation treatment effect, the investment cost of the static pressure compaction pile is greatly reduced.
本发明公开了一种湿陷性黄土地质静压挤密桩施工方法，采用素土挤密桩处理地基，通过原地面处理、测量定位、静压成孔、成孔检查、填料含水率试验、素土分层夯填、综合检查和成桩进行静压挤密桩施工。本发明有效解决湿陷性黄土地质的静压挤密桩施工问题，施工安全，质量可靠，进度快，投入成本低，相比于锤击沉管成孔、振动沉管成孔以及冲击成孔等传统挤密桩施工方法，静压成孔成本费用偏高，但对比于相同地基处理效果的CFG桩及预制方桩而言，采用静压挤密桩投入费用大大减少。
