Large-diameter tubular pile cylindrical fan foundation structure and construction method
The invention discloses a large-diameter tubular pile cylindrical fan foundation structure and a construction method. The wind turbine foundation structure comprises a large-diameter pipe pile, a pile shoe and a pre-stressed anchor cable, the pile shoe is connected to the bottom of the large-diameter tubular pile; a plurality of tubular pile preformed holes which extend in the axial direction of the large-diameter tubular pile and are through are formed in the large-diameter tubular pile, through pile shoe preformed holes are formed in the pile shoe, and the pile shoe preformed holes are communicated with the tubular pile preformed holes; the pre-stressed anchor cables are inserted into the pipe pile preformed holes and the pile shoe preformed holes; an anchor plate is arranged at the bottom of the pre-stressed anchor cable; concrete is poured into the tubular pile preformed hole and the pile shoe preformed hole; the lower end of the pre-stressed anchor cable, the anchor plate, the lower portion of the large-diameter pipe pile and the pile shoe are all anchored in a foundation. The structure that the large-diameter pipe piles are matched with the pre-stressed anchor cables is adopted, fatigue damage of steel bars and concrete is avoided, the crack resistance and durability of the foundation structure are improved, and the safety of the foundation structure is guaranteed.
本发明公开了一种大直径管桩筒形风机基础结构及施工方法；该风机基础结构包括大直径管桩、桩靴和预应力锚索；所述桩靴连接在大直径管桩的底部上；所述大直径管桩上设有多个沿大直径管桩的轴向延伸且贯通的管桩预留孔，且桩靴上设有贯通的桩靴预留孔，桩靴预留孔与管桩预留孔相通；所述预应力锚索插入管桩预留孔和桩靴预留孔中；预应力锚索的底部设有锚板；管桩预留孔和桩靴预留孔中灌注有混凝土；预应力锚索的下端、锚板、大直径管桩的下部以及桩靴均锚固于地基中。本发明采用大直径管桩和预应力锚索相配合的结构，避免了钢筋和混凝土的疲劳破坏，提高了基础结构的抗裂性、耐久性，保证了基础结构的安全性。
