具体实施方式
下面详细描述本公开的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
本公开的实施例提供一种预制装配式风电基础，以下参照图1至图6进行详细阐述。
一种预制装配式风电基础，参照图1，包括：周侧支撑组件1以及中心承重组件2；
周侧支撑组件1，包括若干Y形预制构件11，每个Y形预制构件11包含一体设置的三块预制板111，每块预制板111的规格相同，多个Y形预制构件11拼接成整体为蜂窝状结构的周侧支撑组件1；
中心承重组件2，包括若干中心承重预制构件21，若干中心承重预制构件21呈圆周阵列相邻排列，若干中心承重预制构件21之间形成有中心空腔22，且中心承重构件与Y形预制构件11固定连接。
其中，参照图1和图3，其中图3中为了具体表明预应力索孔6的位置，未示出锚栓孔5位置，锚栓孔5位置参照图1。中心承重预制构件21具体包括一体设置主体承重构件211和连接构件212，主体承重构件211为多棱柱，本实施例中设置为正六棱柱，且中心承重预制构件21在拼接中心承重组件2时，每个主体承重构件211的相邻面彼此贴合，在中心围成正六边形的中心空腔22；且中心承重预制构件21侧壁上在水平方向贯穿设置有预应力索孔6，本实施例中设置有两条预应力索孔6，预应力索孔6设置位置需要保证贯穿中心承重预制构件21正对的两个平面，同时相邻的两个中心承重预制构件21的预应力索孔6正对设置，预应力索可以穿过两个中心承重预制构件21相互平行的4个平面；连接构件212设置于主体承重构件211不用于拼接形成中心承重组件2以及中心空腔22的侧面上，且连接构件212朝向周侧支撑组件1一端设置有用于配合Y形预制构件11连接的连接段，连接段上设置有用于与Y形预制构件11固定连接的螺栓连接孔4，同时在连接构件212上配合主体承重构件211上的预应力索孔6设置有通孔，从而在中心承重预制构件21拼接完成之后，可以通过预应力索进行将相邻中心承重预制构件21固定连接。并且在每个中心承重预制构件21的端面上沿竖直方向设置有若干锚栓孔5，以供锚栓插入，且在组装拼接好的中心承重组件2的水平截面上，锚栓孔5以中心空腔22的中心为圆心呈圆周阵列排列，且预应力索孔6与锚栓孔5排列的圆周阵列所在圆环相切或相离设置。由于在中心空腔22的存在，工作人员在对锚栓进行检修时可以进入中心空腔22内，从而方便了工作人员对锚栓的检修作 业。
在一些实施例中，单个Y形预制构件11的三块预制板111中任意两块之间的夹角相同，本实施例中设置为120°，且三块预制板111的端面任意两端面之间的夹角呈与任意两预制板111之间的夹角互补，本实施例中设置为60°。在一些实施例中，考虑到当遇到一些由于地质、地形因素影响无法或不方便直接在地面上进行预制构件拼装搭接的作业的情况，需要在Y形预制构件11底部一体设置有底板3，具有底板3的Y形预制构件11可以方便工作人员在多种地质、地形条件下进行风电基础的施工作业，且由于各个Y形预制构件11拼接后围成的图形为复合蜂窝状的正六边形或其他多边形的形状，参与拼接的每个Y形预制构件11对应的底板3同样需要彼此之间不产生干涉且能完整的形成同一个平面，因此底板3优选为三角形，且底板3的每个角的角度均需要与相对的预制板111夹角互补，本实施例中底板3设置为正三角形，且底板3的每个角呈60°。
在一些实施例中，在每个Y形预制构件11的每个预制板111上均设置有贯通至端面螺栓连接孔4，螺栓连接孔4从预制板111拼接的端面贯通至与该端面相邻的侧面，且在侧面上对应螺栓连接孔4位置设置有用于容纳螺栓头的沉孔；相邻Y形预制构件11中相互接触的预制板111上的螺栓连接孔4正对设置，以使相邻Y形预制板111使用螺栓穿过两个正对的螺栓连接孔4固定连接。本实施例中每个预制板111连接端面相邻的两个侧面上均设置有一个螺栓连接孔4。
在一些实施例中，考虑到Y形预制构件11彼此之间连接的稳定性以及紧密性，在相邻Y形预制构件11之间设置有灌浆连接层7。当相邻Y形预制构件11通过螺栓完成连接之后，工作人员再次对相邻Y形预制构件11之间进行灌浆作业，从而形成灌浆连接层7。
其中，以中心承重组件2位置中心，呈辐射状远离中心方向上，处于不同同心圆上的Y形预制构件11根据支撑需求具有不同的功能作用，为了更好的对中心承重组件2进行支撑，周侧支撑组件1的高度由中心承重组件2朝向远离中心承重组件2方向呈阶梯状依次降低，也即Y形预制构件11的高度由中心承重组件2朝向远离中心承重组件2方向呈阶梯状依次降低，也即Y形预制构件11的高度根据使用功能不同进行调整。且在不同的实际施工情况下，Y形预制构件11的高度根据实际施工情况的不同也可以进行调整。
其中，由于Y形预制构件11的拼接形成的蜂窝状结构，使得整个周侧支撑组件1中形成多个蜂窝空腔12，每个蜂窝空腔12内设置有填充物，填充物可以为泥土、碎石、沙石等，本实施例中填充物设置为施工风电基础时的回填土。且填充物需要根据实际承重需求进行不同数量的填充。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含 于本公开的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本公开的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
尽管已经示出和描述了本公开的实施例，本领域的普通技术人员可以理解：在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公开的范围由权利要求及其等同物限定。
本公开所有实施例均可以单独被执行，也可以与其他实施例相结合被执行，均视为本公开要求的保护范围。
