Combined cylinder structure draught fan foundation
The invention discloses a combined cylinder structure draught fan foundation. A circular expansion foundation and an annular structure are included. The bottom of the circular expansion foundation isin rigidity connection with the top of the annular structure. The top face of the circular expansion foundation is flush to the ground. The annular structure comprises a plurality of pressure fillingpiles, the pressure filling piles are arranged in the circumference direction of the annular structure, and the diameter of the circular expansion foundation is larger than or equal to the outer diameter of the annular structure. The foundation soil pressure on the side face of the combined large-diameter cylinder structure foundation is sufficiently utilized for resisting the large bending momentload of a draught fan, meanwhile, the expansion foundation and the large annular structure face are used for bearing on the section with the large bending moment and shear force, and the strength ofa combined structure body is sufficiently utilized; and the foundation can be applied to all land draught fan foundations, particularly to a draught fan foundation needing foundation treatment and a natural foundation of a large-volume wind power unit, and obvious economic advantages are achieved.
本发明公开了一种组合式圆筒结构风机基础，包括圆形扩展基础和环形结构，圆形扩展基础的底部与环形结构的顶部刚性连接，圆形扩展基础的顶面与地面平齐，环形结构包括若干压灌桩，压灌桩沿环形结构的圆周方向排列，圆形扩展基础的直径大于等于环形结构的外径；本发明充分利用了组合大直径圆筒结构基础侧面的地基土压力来抵抗风机的大弯矩载荷，同时在弯矩和剪力较大截面采用扩展基础和大环形结构面承担，充分利用了组合结构体的强度；此基础可应用于所有陆上风机基础，特别是需要进行地基处理的风机基础和大容量风电机组的天然地基基础，具有明显的经济优势。
