Abstract

本发明公开了一种海上逆作法安装装配式风力发电机施工方法，（1）将风力发电机的底盘、立柱、风叶全部在陆地或港池组装好，底盘上预留有可穿过桩的孔洞，在立柱外周竖向放置预制桩，桩底***预留孔洞，桩身与立柱临时固定防止脱落；然后用拖船拉到预定海域，将整体装置沉至海底预定位置；（2）通过拖船上或者浮坞上设置的吊机线吊住预制桩，解除预制桩与立柱的临时固定，通过振动锤将桩打入至海底预定深度；（3）通过固定结构件将桩顶与底盘永久固定连接。本发明中风机装置全部在工厂预制装配，质量可控，在预定海域仅需下沉、打桩，该逆作法施工方便，无需额外搭设海上施工平台、可减小或取消沉箱，大大节约成本。

Description

海上逆作法安装装配式风力发电机施工方法
技术领域
本发明涉及一种海上逆作法安装装配式风力发电机施工方法。
背景技术
现有的海上风力发电机安装时，一般采用二种方法：一是：先在海底打桩，然后在桩基础上固装基础平台和筒柱，再在基础平台或筒柱上安装风叶，即传统顺作法，该方法步骤多，工期长，现场施工不可控因素多；二是：采用沉箱式底盘，将风机整体安装好后拉到预定海域，然后将底盘抽气负压沉入海底软土中，由于风机重达2000-4000吨且没有桩基础，底盘直径一般需要30多米，高度10多米，消耗钢材等原材料量巨大，成本高昂。
发明内容
本发明的目的在于提供一种施工方便、成本低的海上逆作法安装装配式风力发电机施工方法。
本发明的技术解决方案是：
一种海上逆作法安装装配式风力发电机施工方法，其特征是：包括下列步骤;
（1）将风力发电机的底盘、立柱、风叶全部在陆地或港池组装好，底盘上预留有可穿过桩的孔洞，在立柱外周竖向放置预制桩，桩底***预留孔洞，桩身与立柱临时固定防止脱落；然后用拖船拉到预定海域，将整体装置沉至海底预定位置；
（2）通过拖船上或者浮坞上设置的吊机吊住预制桩，解除预制桩与立柱的临时固定，通过振动锤将桩打入至海底预定深度；
（3）通过固定结构件将桩顶与底盘永久固定连接。
所述固定结构件为插销、榫卯、螺栓螺丝结构件中的一种或多种。
步骤（3）固定连接后，在固定结构件周围浇筑水下速凝混凝土。
本发明中风机装置全部在工厂预制装配，质量可控，在预定海域仅需下沉、打桩，该逆作法施工方便，无需额外搭设海上施工平台、可减小或取消沉箱，大大节约成本。
下面结合实施例对本发明作进一步说明。
具体实施方式

（2）通过拖船上或者浮坞上设置的吊机的钢绞线吊住预制桩，解除预制桩与立柱的临时固定，通过振动锤将桩打入至海底预定深度；桩顶与底盘的底板等高；
（3）通过固定结构件将桩顶与底盘永久固定连接。
所述固定结构件为插销、榫卯、螺栓螺丝结构件中的一种或多种。
步骤（3）固定连接后，在固定结构件周围浇筑水下速凝混凝土。
