Construction method of offshore composite foundation
The invention discloses an offshore composite foundation and a construction method thereof, belongs to the field of ocean engineering construction, and aims to provide an underwater composite foundation structure which is high in bearing capacity, short in construction period and good in economical efficiency and a construction method of the underwater composite foundation structure. According to the technical scheme, the offshore composite foundation comprises a suction bucket, a steel pipe pile and an anchoring part, an opening of the suction bucket faces downwards and is inversely buckled on a covering layer, the steel pipe pile penetrates through an inner barrel of the suction bucket, the lower end of the steel pipe pile is located on bedrock, a cushion layer is arranged at the pile bottom of the steel pipe pile, an anchoring hole is formed in the cushion layer, and a drill hole located in the bedrock is formed in the bottom of the anchoring hole. An anchoring part is arranged in the drill hole and anchored to bed rock, the upper end of the anchoring part penetrates through a spring and is fixedly connected with a cushion block, and a prestress anchoring system is formed. The construction method of the offshore composite foundation is used for constructing the offshore composite foundation in a shallow covering layer rock seabed sea area. The method is used for design and construction of the offshore wind power foundation in the shallow covering layer rock foundation seabed.
本发明公开了一种海上复合基础及其施工方法，属于海洋工程建设领域，目的是提供一种承载力高、施工周期短、经济性好的水下复合基础结构及其施工方法。本发明采用的技术方案是：海上复合基础，包括吸力桶、钢管桩和锚固件，吸力桶开口朝下并倒扣于覆盖层，吸力桶的内筒穿设钢管桩，钢管桩的下端坐落于基岩，钢管桩的桩底设置垫层，垫层内设置锚固孔，锚固孔的底部为位于基岩内的钻孔，钻孔内设置锚固件并锚固于基岩，锚固件的上端穿设弹簧并固定连接垫块，形成预应力锚固体系。海上复合基础的施工方法，用于在浅覆盖层岩石海床海域施工上述海上复合基础。本发明用于浅覆盖层岩石地基海床中海上风电基础的设计与施工。
