技术领域
本发明涉及海上风机浮式基础施工及风机安装技术领域，尤其涉及一种海上风机浮式基础整体式安装工艺。
背景技术
随着海上风电开发，风电场海域水深逐步加深，在水深达到40米，甚至更深海域时，传统的固定式基础造价偏高，并且深海海域，可用的船舶较少，对施工设备的要求较高，施工台班费高，而浮式基础具有明显优势，因此减少海上作业工序，降低工程造价，是深海浮式风机基础亟待研究、解决的课题。
因此，需要提供一种海上风机浮式基础整体式安装工艺来解决上述问题。
发明内容
为了解决该问题，本发明公开了一种海上风机浮式基础整体式安装工艺，它是一种海上风机浮式基础施工及风机安装相结合的施工工艺，此工艺施工便捷、安装效率高、作业安全性好。一种海上风机浮式基础整体式安装工艺，所述安装工艺的具体方法步骤如下：
步骤一，筒形浮式基础岸上制作
步骤二，筒形浮式基础下水
步骤三，筒形浮式基础平卧拖运至风机拼装海域
步骤四，筒形浮式基础竖立扶正
步骤五，竖立的筒形浮式基础嵌入固定于海上施工平台
步骤六，筒形浮式基础空腔内部填充砂石、灌浆料或细石混凝土
步骤七，风机海上拼装安装至浮式基础
步骤八，风机基础及风机整体浮式拖运至机位
步骤九，筒形浮式基础通过不锈钢锚链锚固至海床面上的钢筋混凝土预埋吊耳上。
本发明的有益效果为：
本发明主要的工序在陆上完成，受天气影响小；风机拼装等工序在海上完成，不需要专门的码头；对海床要求低，不需要专门的海床找平，工程造价低，为深海浮式风机基础的施工及风机安装大规模建设提供指导，具有较强的推广价值。
