Soft-scattered-rigid ternary combined pile composite foundation of saturated soft soil and construction method of soft-scattered-rigid ternary combined pile composite foundation
The invention relates to the technical field of geotechnical engineering foundation treatment, and particularly discloses a soft-scattered-rigid ternary combined pile composite foundation of saturated soft soil, which comprises a soft-scattered-rigid ternary combined pile, and the soft-scattered-rigid ternary combined pile comprises three mixing piles which are mutually engaged and lapped, the three breathable discrete piles are arranged at the axis positions in the three stirring piles correspondingly, and the permeable pipe pile is arranged at the center position of the lap joint area in the three stirring piles. The basic group reinforcement technology, the carbonization reinforcement technology and the multi-element combined pile technology are combined in composite foundation treatment, the pile body strength is rapidly improved, the low-cost pile periphery reinforcement range expansion and foundation deep drainage are achieved through multi-element piles, it is ensured that the pile forming quality is reliable, and the construction period is shortened. And the stability requirement of a fill slope influence area is met by preventing surrounding flow damage of soil between piles. The method is particularly suitable for treatment engineering of embankments, river levees and fill slope foundations, and meanwhile the advantages of being environmentally friendly, rapid, efficient, economical, applicable and the like are achieved.
本发明涉及岩土工程地基处理技术领域，具体公开一种饱和软土的柔‑散‑刚三元联合桩复合地基，包括柔‑散‑刚三元联合桩，所述柔‑散‑刚三元联合桩包括三根相互咬合搭接的搅拌桩，三根透气散体桩分别设置在三根所述搅拌桩内部轴心位置，一根透水管桩设于三根所述搅拌桩内部搭接区域中心位置。本发明结合碱基发加固技术、碳化加固技术、多元联合桩技术于复合地基处理中，实现桩体强度快速提高，以多元桩实现低成本扩大桩周加固范围与地基深层排水，确保成桩质量可靠，通过预防桩间土绕流破坏以满足填方边坡影响区稳定性要求。特别适合应用于路堤河堤、填方边坡地基处理工程，同时发挥了环境友好、快速高效、经济适用等优势。
