Offshore wind power hollow interlayer concrete-filled steel tube single-pile foundation structure and construction method
The invention relates to an offshore wind power hollow interlayer concrete-filled steel tube single pile foundation and a construction method. The single pile foundation comprises three sections of prefabricated hollow interlayer concrete-filled steel tubes which are the upper-section prefabricated hollow interlayer concrete-filled steel tube, the middle-section prefabricated hollow interlayer concrete-filled steel tube and the lower-section prefabricated hollow interlayer concrete-filled steel tube, wherein the lower end of the upper-section prefabricated hollow interlayer concrete-filled steel tube is fixedly connected with the upper end of the middle-section prefabricated hollow interlayer concrete-filled steel tube, the lower end of the middle-section prefabricated hollow interlayer concrete-filled steel tube is fixedly connected with the upper end of the lower-section prefabricated hollow interlayer concrete-filled steel tube, the three sections of prefabricated hollow interlayerconcrete filled steel tubes comprise outer steel tubes, inner steel tubes and concrete interlayers, and the position between the outer steel tubes and the inner steel tubes are filled with the concrete interlayers. According to the foundation and the method, the horizontal bearing performance of a single pile can be improved, the pile diameter can be reduced under the condition of providing the same horizontal rigidity as a common steel pipe pile, the requirements of an existing pile sinking device and driller rock embedding device for the pile diameter are met, and meanwhile, the steel consumption is greatly reduced, so that the economical efficiency is good.
本发明涉及一种海上风电中空夹层钢管混凝土单桩基础及施工方法，该单桩基础，包括三段预制中空夹层钢管混凝土，分别为上段预制中空夹层钢管混凝土、中段预制中空夹层钢管混凝土和下段预制中空夹层钢管混凝土，上段预制中空夹层钢管混凝土下端和中段预制中空夹层钢管混凝土上端固定连接，中段预制中空夹层钢管混凝土下端和下段预制中空夹层钢管混凝土上端固定连接；三段预制中空夹层钢管混凝土均包括外钢管、内钢管和混凝土夹层，混凝土夹层填充在外钢管和内钢管之间。本发明可以提高单桩的水平承载性能，能在与普通钢管桩提供相同水平刚度的条件下减小桩径，满足现有的沉桩设备及钻工嵌岩设备对于桩径要求，同时大幅降低钢材用量，经济性好。
