Annular prefabricated assembly beam plate type fan foundation and installation method
The invention relates to the technical field of wind driven generator foundation structures, and discloses an annular prefabricated assembly beam plate type fan foundation which is characterized in that an annular prefabricated assembly beam plate type fan foundation cushion layer is poured at the bottom of a corresponding area of a wind driven generator foundation; the annular structure is formed by annularly distributing a plurality of precast beam and slab units, the annular structure is arranged above the cushion layer, the annular structure and the cushion layer are in filling connection through a bottom grouting body, and any two adjacent precast beam and slab units are in filling connection through an abutted seam grouting body; the annular prestressed cable is arranged on the outer side of the annular structure in a surrounding mode, and the annular prestressed cable is tightly attached to the outer side of the annular structure and tensioned; and the anchor bolt assemblies are arranged on the precast beam and slab units respectively and used for being connected with a bottom flange of the fan tower drum. The overall strength of the assembly type fan foundation can be improved, and the shock resistance of the fan foundation is improved. Meanwhile, the invention further provides an installation method of the annular prefabricated assembly beam plate type draught fan foundation.
本发明涉及风力发电机基础结构技术领域，公开了一种环向预制装配梁板式风机基础，本发明的环向预制装配梁板式风机基础垫层，浇筑在风力发电机基础对应区域底部；由若干个预制梁板单元环向分布组成的环形结构，环形结构设置在垫层上方，环形结构与垫层之间通过底部注浆体填充连接，任意两相邻预制梁板单元之间通过拼缝灌浆体填充连接；环向预应力索，环绕设置在环形结构的外侧，环向预应力索紧贴环形结构的外侧并张紧；锚栓组合件，分别设置在各预制梁板单元上，用于连接风机塔筒的底法兰。其能够提高装配式风机基础的整体强度，提高风机基础的抗震能力。同时，本发明还提供一种该环向预制装配梁板式风机基础的安装方法。
