Offshore wind turbine cylindrical foundation underwater construction floating structure and method
The invention relates to an offshore wind turbine cylindrical foundation underwater construction floating structure and method. The construction floating structure comprises a cylindrical foundation, a prefabricated platform and a sinking platform, wherein the prefabricated platform is fixed in a harbor basin, a steel-clad concrete polygonal cylinder is constructed on the prefabricated platform, the steel-clad concrete polygonal cylinder is connected to a floating box to inflate and drain the floating box, the steel-clad concrete polygonal cylinder is separated from the prefabricated platform, the steel-clad concrete polygonal cylinder is transferred to the sinking platform fixed on a mud surface, and subsequent pouring of the steel-clad concrete polygonal cylinder and construction of a concrete bottom plate and a concrete transition section are carried out above the water surface until the cylindrical foundation is completely constructed. According to the structure, a cylindrical foundation construction site is placed in a harbor basin, dependence on a large wharf is reduced, a large gantry crane is not needed in the construction process, the cylindrical foundation can be rapidly, conveniently and economically towed and transported to a designated machine position to be installed after being constructed, construction equipment can be repeatedly used, and the economical efficiency is good.
本发明涉及一种海上风机筒型基础水中建造起浮结构及方法，该建造起浮结构，包括筒型基础、预制平台和沉底平台，预制平台固定在港池中，包钢混凝土多边形筒建造在预制平台上，包钢混凝土多边形筒与浮箱连接，向浮箱充气或排水，使包钢混凝土多边形筒与预制平台脱离；将包钢混凝土多边形筒转移到固定在泥面上的沉底平台上，在水面以上进行包钢混凝土多边形筒后续浇筑，以及混凝土底板和混凝土过渡段的施工，直至筒型基础全部建造完成。本发明通过将筒型基础施工场地放置在港池中，减少了对大型码头的依赖，建造过程不需要大型龙门吊，建造完成后可以快速、方便且经济的方式，拖航运输到指定机位安装。且施工设备可以反复使用，经济性较好。
