摘要
通过对相关地方技术规程进行优化组合,提出螺旋锥体挤土桩施工方法及螺旋锥体挤土压灌桩技术理论。螺旋锥体挤土压灌桩的单桩承载力高,在同等条件下可减小桩长,缩小桩径,可节约材料,降低造价。
Through the optimization and combination of relevant local technical regulations, the construction method of spiral cone compaction pile and the technical theory of spiral cone compaction and compaction pile are proposed. The single-pile bearing capacity of the spiral cone compaction pile is high, and under the same conditions, the pile length can be reduced and the pile diameter can be reduced, which can save materials and reduce the cost.
