Single-pile foundation of offshore wind power vibroflotation cemented pile reinforced soft soil foundation and construction method
The invention provides a single-pile foundation of an offshore wind power vibroflotation cemented pile reinforced soft soil foundation and a construction method. The single-pile foundation comprises a single pile and vibroflotation cemented piles, wherein the vibroflotation cemented piles are arranged around the single pile; the vibroflotation cemented piles are formed in a seabed soft soil layer and a supporting layer through a construction method of combining a deep sea gravel pile vibroflotation pile forming process and an underwater self-compacting cement-based cementing material self-flow grouting process; the vibroflotation cemented piles and soil bodies among the piles form a vibroflotation cemented pile composite foundation; and the pile body strength of the vibroflotation cemented piles in the composite foundation is sequentially increased from an outer ring to an inner ring and is sequentially decreased from the upper part to the lower part. The vibroflotation cemented piles effectively improve the bearing capacity of the soft soil layer, the applicability of the single-pile foundation in a shallow covering layer seabed and an offshore deep water wind power plant is expanded, meanwhile, a scouring structure does not need to be additionally arranged, and the single-pile foundation has the characteristics of being low in foundation manufacturing cost and construction cost, high in construction efficiency and easy and convenient to operate.
一种海上风电振冲胶结桩强化软土地基的单桩基础及施工方法，它包括单桩和振冲胶结桩，振冲胶结桩环绕于单桩设置，通过深海碎石桩振冲成桩工艺和水下自密实水泥基胶凝材料自流灌浆工艺胶结相结合的施工方法在海床软土层和持力层中形成振冲胶结桩，振冲胶结桩与桩间土体构成振冲胶结桩复合地基，所述复合地基中振冲胶结桩的桩身强度由外环至内环依次递增、由上部至下部依次递减。振冲胶结桩有效提高软土层承载能力，扩展单桩基础在浅覆盖层海床和近海深水风电场中的适用性，同时无需另设防冲刷结构，基础制造成本和施工成本低，施工效率高，操作简单方便的特点。
