Novel thin-wall large-diameter single pile-barrel composite pile foundation and installation method thereof
The invention provides a novel thin-wall large-diameter single pile-barrel composite pile foundation and an installation method thereof. The novel thin-wall large-diameter single pile-barrel compositepile foundation comprises an outer barrel-shaped foundation and a thin-wall variable-cross-section single-pile foundation located in the middle of the outer barrel-shaped foundation, and the thin-wall variable-cross-section single-pile foundation comprises an upper foundation part and a lower foundation part; the diameter of the upper foundation part is smaller than that of the lower foundation part; a plurality of annular plates are arranged at the inner side of the upper foundation part at intervals from top to bottom, a plurality of vertical rib plates are evenly arranged between the outerwalls of the annular plates and the inner wall of the upper foundation part, a plurality of annular reinforcing beams are arranged at the outer side of the lower foundation part in the circumferential direction, and Y-shaped reinforcing ribs are arranged between the adjacent annular reinforcing beams; the pile foundation is reasonable in design, can provide higher bearing capacity and rigidity compared with a traditional single-pile foundation, and can serve as a foundation form with higher fan power; in the aspect of the specific structure, the wall thickness of the same foundation is optimized, the structural strength is guaranteed, steel is saved, and the economical efficiency is good; and the bearing performance of the foundation can be remarkably improved as the foundation is connected with the outer barrel-shaped foundation in a grouting manner.
本发明提供一种新型薄壁大直径单桩‑桶复合桩基及其安装方法，包括外侧桶形基础以及位于外侧桶形基础中部的薄壁变截面单桩基础，薄壁变截面单桩基础包括基础上部和基础下部，基础上部的直径小于基础下部，基础上部内侧由上至下间隔设有多个环形板，环形板外壁与基础上部内壁之间均匀设有多个竖向肋板，基础下部外侧周向设置有多个环向加强梁，相邻环形加强梁之间设有Y型加强肋。本发明设计合理，相比于传统单桩基础其能够提供更高的承载能力和刚度，能够作为更大风机功率的基础形式；在具体结构方面通过同基础的壁厚进行优化，既保证的结构强度又节约钢材，经济性好；与外侧桶形基础通过注浆方式连接，能够显著提高其承载性能。
