High-rise platform building pile foundation
The invention discloses a high-rise platform building pile foundation. The high-rise platform building pile foundation is characterized by comprising a precast tubular pile and a sleeve which is arranged at the top of the precast tubular pile in a sleeving manner; a grouting hole, an exhaust vent and multiple anchor ribs are arranged on the sleeve; and the sleeve is detachably arranged on the precast tubular pile. According to the high-rise platform building pile foundation, concrete slurry is injected into the precast tubular pile at a high pressure through the grouting hole so that the precast tubular pile, the sleeve, an internal casing, a bolt, a reinforcing rib and an inclined rod are integrated, and therefore, the integrity, reliability and shear capacity of the pile foundation are enhanced; after pile foundation is connected with a bearing platform through the anchor ribs, due to the arranging of the sleeve, the internal casing, the bolt and the reinforcing ribs, the structuralstability of the pile foundation and the bearing platform are enhanced, and the anti-bending capacity and shear capacity of the connecting position of the pile foundation and the bearing platform arealso improved.
本发明公开了一种高承台建筑桩基，其特征是：包括预制管桩和套设于预制管桩顶部的套筒，所述套筒上设有灌浆孔、排气孔和多根锚固筋，所述套筒可拆卸设于预制管桩上。该高承台建筑桩基通过灌浆孔将混凝土浆液高压注入预制管桩内，使预制管桩、套筒、内套管、螺栓、加强筋和斜向杆成为一体，提高了桩基的整体性、可靠性及抗剪能力；通过锚固筋连接承台后，由于套筒、内套管、螺栓和加强筋的设置，提高了桩基与承台的结构稳定性，还提高了桩基与承台的连接位置的抗弯和抗剪能力。
