Abstract

本发明涉及拉紧的-带腿的海上被淹没的平台，在混凝土-钢的混合方案中，具有预应力混凝土的中心体(1)，钢周边结构(2)，通过钢加固装置(9)、(10)、(5)连接至中心体。本发明还涉及用于这样的平台的底层(15)。

Description

在混凝土-钢混合方案中的用于远海中的海上风力电站的能沉入水中的拉紧锚定的平台
技术领域
本发明的目的是根据在意大利专利Nr.0001331996中说明的一些特征，具有块状的冲断层的能沉入水中的海上风平台，其由混凝土-钢混合结构构成。所述意大利专利Nr.0001331996涉及具有用于风力电站的支撑基底和海洋生物养殖工厂的双功能的能沉入水中的漂浮的平台。所述全部通过使用具有块状冲断层的部分地沉入水中的平台来实施，ballastable且传输直至它被锚定至放置在海底上的底层上的位置；所述锚定用连接拉杆来实施，易于支撑由于漂浮力和由于由海和风获得的外力造成的甚至是组合的重量、压力和作用力。 
背景技术
发明内容
本发明的目的是克服关于使用根据专利Nr.0001331996的特征的平台的一些关键的方面，在关于所述配置的特定情形中，关于在实施方式中使用的材料、用于锚定平台至底层的系统以及将所述底层用作半沉入水中的浮码头的使用，因此在构造工厂中的平台被构造，且用其所述平台被从构造工厂运输至所述位置。 
本发明的平台物体也是沉入水中的平台，所述平台具有块状冲断层，装配有由预应力混凝土制成的轴向对称的中心体和通过多个加固构件的方式连接至其上的由钢制成的周边结构。这种类型的方案允许实现几个优点：通过消除或然而是限制以采用特定工艺(焊接等)的合格的建筑技术，用于包含所述结构的整个质量、用于保证高的机械阻力特征，用于简化和使所述构造经济化，用于允许实施平台自身。 
附图说明
本发明的详细描述将具体地参考表格1/3至3/3，其中并不是绝对地为了限制性的目的示出了本发明的优选的实施例的例子。 
具体地： 
图1示出了所述系统的整体配置的方案； 
图2示出了底层的平面和剖面视图； 
图3示出了能沉入水中的平台的平面视图。 
具体实施方式
如从上述的图中所看到的，平台包括由预应力混凝土制成的中心体1、由钢2制成的周边结构，所述周边结构通过埋入到混凝土中的由钢9制成的特定的插入件、由钢支撑的拉杆以及加强环5连接至中心体。中心体主要是支撑风轮机的由钢12制成的塔。 
本发明的基本特征是用于锚定平台至底层15的系统，包括多个纺织绳索6，其被向下锚定至底层15，向上延伸以刺入到中心体1的内部。拉紧系统11放置在中心体的顶部，计划用于甚至通过大量的仪表允许修改绳索的长度，对绳索的预负载起作用。这一特征还允许通过简单地从平台的内部作用甚至由几个仪表来补偿底层15在各个海洋洋流的作用之后在具有巨大的沙层的所有位置上方的可能的垂直下沉。所述方案还包括装置7和8，易于保护从平台向外延伸的绳索，和最小化/消除沿着绳索的路线的摩擦。相反地，专利Nr.0001331996的平台已有的物体的特征在于使用了拉杆(例如链条)，其在周边垂直地将平台束紧至配重(底层)。这样的链条被用装配有机械安全装置的液压千斤顶锚定至平台的腿部，且因此是可以以受限制的方式调节的。 
在这样的情形中，必须基于海床的深度和状况限定链条的长度，使得实施期望的预负载到拉杆上。这需要进行海床的精确勘察。另外，在安装期间，且之后为了保养的目的，参考方案需要使用水下驱动装置。 
在本发明中，由于使用所述纺织绳索6和包含在中心体1的顶部的相关的拉紧系统，克服了这些问题。 
另外，至于材料的使用被关注，仅由预应力的混凝土制成的平台包括也由混凝土制成的在下部束紧至周边冠的中心体，其将具有由80％的周边部分和20％的中心体构成的重量。另一方面，整体地由钢制成的结构将在周边部分中是相对轻的，但是将需要长的时间周期、合格的建筑手艺和高的实施成本。 
本发明的由预应力混凝土和钢物体制成的结构，通过消除其的不利，为整体地由混凝土制成和整体地由钢制成的方案增添了优点。专利Nr.0001331996的方案被提供以运输平台至所述位置且随后通过拉杆的方式将其锚定至之前布置在海床上的底层。相反地，本发明的方案包括具有自由体积的由预应力混凝土15制成的底层，其可以被空气加压且可能是被淹没的，其在其的建造之后可能用作用于在其上构造平台的半沉入水中的浮码头，从构造工厂至所述位置的底层加平台的联合的运输。 
此外，在单元的安装期间，在其的淹没期间底层通过所述绳索系统6保持锚定至在其上直立的平台，其被保持成张紧的，且对系统的稳定性起到积极的作用。
