Offshore wind power cylindrical foundation and construction method thereof
The invention relates to the technical field of offshore wind power, in particular to an offshore wind power cylindrical foundation and a construction method of the offshore wind power cylindrical foundation. The offshore wind power barrel-shaped foundation comprises a negative pressure barrel, a transition section and a center pile, the negative pressure barrel is hollow, the bottom of the negative pressure barrel is provided with an opening communicating the outside with the inner space of the negative pressure barrel, the transition section is coaxially arranged on the top of the negative pressure barrel, and the top of the transition section communicates with the bottom of the negative pressure barrel to form a penetration hole; the center pile is matched with the penetration hole in an inserted mode, a water pumping opening communicated with a water pump is formed in the top of the negative pressure cylinder, and the top of the transition section is connected with the bottom of a fan unit tower cylinder. According to the offshore wind power barrel-shaped foundation, a large part of bearing capacity is additionally provided through interaction of the center pile and the soil body, and the negative pressure barrel and the center pile are connected into a whole and jointly stressed, so that the structural bearing capacity is met, the system engineering amount is saved, and the requirements for manufacturing, transportation and installation are greatly reduced.
本发明涉及海上风电技术领域，尤其涉及一种海上风电筒形基础和该海上风电筒形基础的施工方法。该海上风电筒形基础包括负压筒、过渡段和中心桩，负压筒的内部中空，负压筒的底部开设有连通外界与负压筒内部空间的开口，过渡段同轴设置在负压筒的顶部上，过渡段的顶部与负压筒的底部相连通形成贯入孔，中心桩与贯入孔插接配合，负压筒的顶部开设有与水泵相连通的抽水口，过渡段的顶部与风机机组塔筒的底部相连接。该海上风电筒形基础通过中心桩与土体的相互作用额外提供了很大一部分承载力，并将负压筒与中心桩连接为一个整体，使两者共同受力，来满足结构承载力，节约了系统工程量，大大降低了对制造、运输及安装的要求。
