Double-layer grouting subdivision type suction bucket-inclined steel pipe pile composite foundation and construction method thereof
The invention relates to the technical field of ocean structure foundations, and provides a double-layer grouting subdivision type suction bucket-inclined steel pipe pile composite foundation and a construction method thereof, and the double-layer grouting subdivision type suction bucket-inclined steel pipe pile composite foundation comprises a suction bucket, a guide pile and a steel pipe pile; the suction barrel comprises a barrel body and compartment rib plates, the barrel body is internally provided with a moving space for the guide pile to move, the compartment rib plates are arranged in the barrel body and around the moving space, and the barrel body is divided into a plurality of side compartments by the compartment rib plates; a sleeve is arranged in the circumferential direction of the guide pile and used for being fixedly connected with a steel pipe pile. Partitioned grouting is performed after the suction buckets and the steel pipe piles are connected through the guide piles, the advantages of the suction buckets and the steel pipe piles are combined, and the soil resistance of a shallow covering layer batholith seabed is fully mobilized through the synergistic effect of the subdivision type suction buckets and the steel pipe pile group piles, so that the transverse bearing performance of the offshore wind turbine foundation is improved; the problems that the foundation rock-socketed construction difficulty is large and the construction process is complex are solved.
本发明涉及海洋结构基础技术领域，提供一种双层注浆分舱式吸力桶‑倾斜钢管桩复合基础及其施工方法，包括吸力桶、导向桩和钢管桩；所述吸力桶包括桶体和隔舱肋板，所述桶体内设有供所述导向桩活动的活动空间，所述隔舱肋板设置在桶体内且设置在活动空间的四周，所述隔舱肋板将桶体分割为多个边舱；所述导向桩的周向上设有套筒，所述套筒用于固定连接钢管桩。本发明通过将吸力桶和钢管桩通过导向桩连接后进行分区注浆，结合了吸力桶以及钢管桩的优点，通过分舱式吸力桶和钢管桩群桩的协同作用充分调动浅覆盖层岩基海床的土体抗力以提高海上风机基础的横向承载性能，避免了基础嵌岩施工难度大且施工工艺复杂的问题。
