Soft soil foundation pile group half-branch pile foundation technology
The invention discloses a soft soil foundation pile group half-branch pile foundation technology, and belongs to the technical field of soft soil foundation pile group foundation treatment engineering. The technology is a unique pile foundation technology for soft soil foundation pile groups, according to secondary splitting grouting of soft soil between group piles of a group pile large-bottom-plate drilling and grouting pile foundation and secondary compaction reinforcement of the soft soil between the piles after pile forming within the 2-3-time pile diameter thickness range (even within the thicker and deeper range) of the soft soil foundation under a large bottom plate, the bearing capacity of a group pile foundation composite foundation is improved, soft soil foundation settlement is reduced and even eliminated, and high bearing platform pile foundation items possibly occurring on the structure due to soft soil foundation settlement are eliminated. The pile group half-branch pile foundation technology is a very effective and innovative inventive patent technology about the pile group foundation of the soft soil foundation.
本发明公开了一种软土地基群桩半支盘桩基础技术，技术属于软土地基群桩基础地基处理工程技术领域，是一种软土地基群桩独特的桩基础技术，是根据对群桩大底板钻孔压浆桩基础的群桩桩间软土二次劈裂注浆并且在大底板下软土地基2～3倍桩径厚度范围内(乃至更厚更深的范围内)进行成桩后的桩间软土二次挤密加固来提高群桩基础复合地基承载能力、减小乃至消除软土地基沉降，消除因软土地基沉降可能出现的结构上的高承台桩基础事项。群桩半支盘桩基础技术是非常有效的创新型关于软土地基群桩基础发明性专利技术。
