Land wind turbine generator extended foundation tubular pile reinforcing structure and construction method
The invention belongs to the technical field of wind generating set foundation reinforcement, and discloses a land wind turbine generator extended foundation tubular pile reinforcing structure and a construction method. The land wind turbine generator extended foundation tubular pile reinforcing structure comprises a wind turbine generator foundation original structure, and the wind turbine generator foundation original structure comprises a concrete structure and an anchor bolt assembly arranged in the concrete structure; a local pressure resistant grouting body is arranged below the top of the anchor bolt assembly; and uniform holes are formed in the outer side of the concrete structure, the bottoms of the holes are subjected to hole expanding treatment, prestressed tubular piles are arranged in the holes, and pores between the prestressed tubular piles and the holes are subjected to grouting treatment to form a bonding grouting body. The prestressed tubular pile is anchored into a rock-soil body through drilling, the concrete anchoring end head and the concrete expanding head are formed through grouting treatment, and large pulling resistance is generated to jointly resist loads transmitted from the upper part.
本发明属于风力发电机组基础加固技术领域，公开一种陆上风机扩展基础管桩加固结构及施工方法；所述结构包括风机基础原有结构，所述风机基础原有结构包含混凝土结构和布置在混凝土结构中的锚栓组合件；所述锚栓组合件顶部下方设有抗局压灌浆体；所述混凝土结构外侧钻有均匀孔洞，所述孔洞底部经过扩大孔洞处理，所述孔洞内设有预应力管桩，所述预应力管桩与孔洞之间的孔隙经灌浆处理形成粘结灌浆体。本发明通过钻孔，将预应力管桩锚入岩土体内，经灌浆处理，形成混凝土锚固端头和混凝土扩大头，由产生较大的抗拔力，共同抵御上部传递下来的荷载。
