Newly constructed or extension constructed wind power foundation on soft foundation shallow covering layer and construction method thereof
The invention discloses a newly constructed or extension constructed wind power foundation on a soft foundation shallow covering layer and a construction method thereof. An annular pile group is arranged in the soft foundation shallow covering layer or in the soft foundation shallow covering layer and around an original wind power foundation; a ring beam is arranged on the annular pile group; a foundation top plate is arranged in the ring beam; or the foundation base of the original wind power foundation surrounded in the ring beam is reutilized; a stand is arranged on the foundation top plateor the foundation base; a reinforcing component for supporting the stand and transmitting the stand load is arranged between the ring beam and the stand; a foundation ring for mounting and fixing a tower drum is fixed on the stand to finish the newly constructed or extension constructed wind power foundation, and the practical demand for newly constructing or extension constructing a wind power plant on the soft foundation shallow covering layer is met. According to the newly constructed or extension constructed wind power foundation, the pressure of the foundation top cover and the active and passive earth pressure of a side wall cylindrical type foundation are utilized to resist large-moment load generated during the fan operating process, the land resource is fully utilized, the bearing capacity is improved, the cost is reduced and the efficiency is improved.
一种软弱地基浅覆盖层上新建或扩建的风电基础及其施工方法，是通过在软弱地基浅覆盖层内、或在软弱地基浅覆盖层内且围绕着原有风电基础设置环形群桩、在环形群桩上设置环梁、在环梁的内部设置基础顶板或将包围在环梁内部的原有风电基础的基础底座加以重新利用、在基础顶板或基础底座上设置台柱、在环梁与台柱之间设置用于支撑台柱并传递台柱荷载的加强构件、在台柱上固定用于塔筒安装固定的基础环，完成新建或扩建风电基础，满足在软弱地基浅覆盖层上新建或扩建风力发电场的现实需要。本发明利用扩展基础顶盖压力及侧壁筒型基础主被动土压力来抵抗风机运行中产生的大弯矩荷载，充分利用了土地资源，提高了承载力，降低了成本，提高了效率。
