Description

一种导管桩与筒组合式的海上风电基础
技术领域
本发明涉及风能工程、新能源领域，具体是一种将导管桩基础与筒型基础相结合而成的组合式海上风电基础。
背景技术
随着全球能源、气候环境等问题的日益突出，风能作为可再生能源受到世界各国的高度关注。风能具有清洁，低成本，取用不尽，开发范围广，装机容量增长空间大，成本下降快，运行安全等优势。相比于陆上风电，海上风电具有风速大、湍流度低、不占耕地等优势。目前，我国海上风电基础多采用桩基础、复合桩基础或管桩，其设计简单，安装工艺成熟，但在横向荷载(风、浪、流)作用下的水平形变较大。宽浅式筒型基础的出现，为海上风机基础的设计提供了新的思路，宽浅式基础可有效抵抗海上风机受到的较大横向荷载，且其结构简单、成本较低、施工便捷快速。
近年来，随着海上复合筒型风机基础及风机一步式安装技术的成功运用，大大减少海上风电基础的建造和施工成本，有较好的工程应用前景。为了进一步推广筒型基础，需要向海底地质条件较差的海域进军，这势必会影响风机基础的运行稳定性。目前来看，较差的地质条件造成的直接影响是增大了筒型基础直径。筒直径的增加，基础材料的用量提升、结构的整体受力变差。同时现有的施工装备和施工技术不能满足要求，需要巨大的装备投入，显著提高了工程的建造费用。这会给现有的生产工艺流程造成巨大的冲击，削弱该基础经济方面的优越性。
目前我国海上风电已经应用了一批海上风电筒型基础结构，拥有相应的建造设备。现有建造设备对筒直径的要求是不超过38m，筒裙长度一般受航道限制不超过12m。而当今风机的容量逐渐增大，风机极限弯矩荷载超过了200MN.m，更深水深和更差的地质情况，导致需要更大筒直径和更长的筒裙深度。筒的直径和筒裙长度的增加导致结构设计难度，结构的建造难度都显著的增加，从而提高工程成本。
发明内容
本发明的目的是为了克服现有技术中的不足，提供一种导管桩与筒组合式的海上风电基础，在降低基础建造费用情况下，保证整个风机结构的设计抗倾要求。充分的利用导管桩基础和筒型基础各自的优势，从而在实现海上风电基础建造成本的降低。
本发明的目的是通过以下技术方案实现的：
一种导管桩与筒组合式的海上风电基础，包括导管桩和筒型基础两部分；所述筒型基础部分由钢筒裙、筒顶盖、主梁、圈梁和过渡段组成，所述钢筒裙的顶部和筒顶盖一体形成为一开口向下的半密封结构，所述筒顶盖上径向均匀布置有3～24根所述主梁，筒顶盖的边缘设置有一圈所述圈梁，所述过渡段设置于筒顶盖上表面中部；
所述导管桩由导管、钢桩、导管支撑和高强度砂浆组成；所述主梁的外侧端部相对应的设置有3～24个导管，所述导管的轴线与竖直方向的夹角为0～15°；导管的下端出口与筒顶盖的下表面齐平，导管的下端出口设置在钢筒裙的外侧；所述钢桩设置于导管中并通过高强度砂浆连接成一整体；所述导管支撑设置于导管外侧并与主梁和圈梁连接并与筒顶盖、主梁和圈梁形成一整体。
进一步的，筒顶盖、主梁、过渡段和圈梁均为钢筋混凝土结构且均浇筑形成为一整体。
进一步的，所述过渡段为空心圆台形结构。
进一步的，所述导管和导管支撑均为钢结构。
与现有技术相比，本发明的技术方案所带来的有益效果是：
本发明组合式海上风电基础，在不增加现有筒型基础直径情况下，通过筒裙外侧的导管桩提供抗倾力矩，从而综合筒型基础和桩基础的优势，同时可以充分的利用现有的一步式筒型基础安装的技术和装备，以及现在大量存在的沉桩设备，从而提高的装备的利用效率和降低工程建设投入，从而实现海上风电建造的成本降低。
