The invention relates to a corrugated steel-concrete combined floating box girder and a construction method thereof, and belongs to the technical field of offshore wind power platforms. Comprising a wind turbine supporting structure, a buoyancy platform, a transfer platform, an external prestressing tendon, a corrugated steel-concrete combined floating box girder, a positioning structure, a wind turbine, a concrete flange plate, L-shaped steel, a flange plate, a stiffening rib, a corrugated web, a reserved bolt hole, a corrugated arch, a shear part, a steel flange, an embedded nut, a partition plate and a bolt, and the corrugated arch is connected with the L-shaped steel and the flange plate in a welded mode. According to the floating platform, the multiple sections of corrugated steel-concrete combined floating box girders are connected through the tensioning external prestressing tendons and the flanges, the stability of an inner cavity of the floating platform and the stability of the platform are improved, an offshore wind power floating foundation suitable for larger megawatts can be formed, the corrugated web H-shaped steel and the corrugated arch are used for replacing traditional concrete slabs, and the construction cost is reduced. The device has the advantages of reducing weight, facilitating marine transportation, shortening the manufacturing period, increasing the structural strength and reducing the cost.
本发明涉及一种波纹钢‑混凝土组合浮式箱梁及其施工方法,属于海上风电平台技术领域,包括风电机支撑结构、浮力平台、转接平台、体外预应力束、波纹钢‑混凝土组合浮式箱梁、定位结构、风电机、混凝土翼缘板、L型钢、法兰板、加劲肋、波纹腹板、预留螺栓孔、波纹拱、剪力件、钢翼缘、预埋螺母、隔板、螺栓,波纹拱与L型钢和法兰板焊接相连。本发明中,通过张拉体外预应力束和法兰将多段波纹钢‑混凝土组合浮式箱梁连接,增加了浮式平台内部空腔和平台平稳性,可形成适用于兆瓦数更大的海上风电浮式基础,使用波纹腹板H型钢和波纹拱替代传统的混凝土板,具有减轻重量、方便海上运输、缩短制造周期、增加结构强度以及降低成本的优点。
