Wind turbine generator foundation recycling method and large unit foundation structure
The invention provides a wind turbine generator foundation recycling method and a large unit foundation structure, and relates to the technical field of wind power generation equipment installment, the method is used for transforming an original small unit foundation, and comprises the steps that foundation soil is excavated to a preset size, concrete and reinforcing steel bars on the outer side of a foundation ring of a stand are broken, and longitudinal reinforcing steel bar connectors on the outer side of the stand are left; scabbling the surface of the foundation plate to expose the bottom radial steel bars of the foundation plate; an anchor bolt cage is installed on the outer side of the foundation ring, reinforcing steel bars of a specific structure are placed on the outer side of the anchor bolt cage, and the reinforcing steel bars of the specific structure are connected with longitudinal reinforcing steel bar connectors on the outer side of the stand and radial reinforcing steel bars on the bottom face; and sealing the mold, pouring newly added concrete, tensioning the steel strand after curing until the strength meets the requirement, applying prestress, and backfilling foundation soil after tensioning is completed, so that the reutilization of the original small unit foundation is completed. Therefore, on the premise that the original small unit foundation can be reserved as much as possible, the original small unit foundation is transformed, and the original small unit foundation can meet the operation requirement of a new unit.
本申请提供一种风电机组基础再利用方法及大机组基础结构，涉及风力发电设备安装技术领域，该方法用以对原小机组基础的改造，包括：开挖地基土至预设尺寸，破除台柱的基础环外侧的混凝土和钢筋，留下台柱外侧的纵向钢筋接头；凿毛基础板的表面，露出基础板的底面径向钢筋；在基础环的外侧安装锚栓笼，锚栓笼的外侧放置特定结构的钢筋，特定结构的钢筋分别与台柱外侧的纵向钢筋接头、底面径向钢筋连接；封模并浇筑新增混凝土，养护至强度满足要求之后张拉钢绞线，施加预应力，张拉完成后回填地基土，即完成原小机组基础的再利用。这样，可以在尽可能多的保留原小机组基础的前提下，对原小机组基础进行改造，使其能够适应新机组的运行需求。
