Cylindrical fan foundation with steel sheet piles
The invention relates to the technical field of wind power generation, in particular to a steel sheet pile cylindrical fan foundation which comprises a fan tower tube, a bearing platform and a hollow sheet pile combined tube, the fan tower tube is connected to the top of the bearing platform, the sheet pile combined tube is arranged at the bottom of the bearing platform, and the sheet pile combined tube is formed by combining a plurality of steel sheet piles in an engaged mode. The steel sheet piles are filled with grouting materials. According to the steel sheet pile cylindrical draught fan foundation, the steel sheet piles are meshed, the problems that open excavation and on-site construction mechanical equipment are expensive, and procedures are complex are solved, and the foundation is convenient to construct, reliable in structure and good in economical efficiency. Open excavation is avoided, and disturbance of soil bearing capacity is avoided. Compared with a conventional pile foundation, the length of the steel sheet pile is reduced by more than 20%, the diameter of the concrete bearing platform is reduced by more than 20%, the overall engineering amount is reduced by more than 20%, and the high construction cost can be reduced under the condition that the strength of the fan foundation is guaranteed.
本发明涉及风电发电技术领域，尤其涉及一种钢板桩筒形风机基础，包括风机塔筒、承台和空心的板桩组合筒，所述风机塔筒连接于承台顶部，所述板桩组合筒设置于承台底部，所述板桩组合筒由多个钢板桩咬合组合，所述钢板桩内部填充有灌浆料。本发明采用的钢板桩筒形风机基础通过钢板桩咬合，避免明挖以及现场施工机械设备昂贵、工序复杂等问题，而且基础施工方便、结构可靠、经济性好。避免明挖、避免了扰动土体承载力。钢板桩长度较常规桩基础桩长度降低20％以上，混凝土承台直径降低20％以上，总体工程量降低20％以上，能够在保证风机基础的强度条件下降低施工高成本。
