The invention discloses an offshore assembly type concrete floating type draught fan waterproof foundation structure which comprises a plurality of concrete foundation arms, a center connecting piece and a connecting flange, one end of each concrete foundation arm is connected with the center connecting piece through the connecting flange, and the other end of each concrete foundation arm is arranged in a radial shape. The concrete foundation arm comprises a plurality of concrete sections which are spliced in sequence, a plurality of hole channels for installation of prestressed tendons are formed in the cylinder wall of each concrete section in the circumferential direction of the concrete section, the hole channels between the adjacent concrete sections are in one-to-one correspondence, and the concrete sections are tightly connected through the prestressed tendons under tensioning of the center connecting pieces. Waterproof layers are arranged on the inner surface and the outer surface of each concrete section, and sealing assemblies are arranged between the joints of the concrete sections and the connecting flanges and between the joints of every two adjacent concrete sections; the waterproof performance of the floating foundation is effectively improved, safe operation of the wind turbine generator is guaranteed, and the floating foundation has the advantages of being convenient to construct, rigid and flexible, safe, reliable and the like.

    本发明公开了一种海上装配式混凝土漂浮式风机防水基础结构,包括混凝土基础臂、中心连接件和连接法兰,混凝土基础臂有多个,多个混凝土基础臂的一端均通过连接法兰和中心连接件相连接,另一端呈放射状设置,混凝土基础臂包括多个依次相拼接的混凝土节段,每个混凝土节段的筒壁上沿其周向设有多个供预应力筋安装的孔道,相邻混凝土之间的孔道一一对应,通过预应力筋在中心连接件的张拉下将多个混凝土节段紧连,每个混凝土节段的内、外表面均设有防水层,混凝土节段与连接法兰的接缝之间以及两个相邻的混凝土节段的接缝之间均设有密封组件;本发明有效提高了漂浮式基础的防水性能,保障风电机组安全运行,具有施工方便、刚柔并济、安全可靠等优点。
