Fabricated anti-floating piled raft foundation
The invention discloses a fabricated anti-floating piled raft foundation, and belongs to the technical field of building foundations. The pre-stressed pipe pile structure comprises a pile pre-fabricated raft block, a pile-free pre-fabricated raft block and a pre-fabricated pre-stressed pipe pile, preformed holes are formed in the positions, where the prestressed pipe piles are prefabricated, of the pile prefabricated raft blocks, and UHPC cross supports are arranged in the preformed holes; connecting steel bars and steel supporting plates are arranged at the tops of the prefabricated prestressed pipe piles, and the prefabricated prestressed pipe piles are connected with the pile prefabricated raft plates through core grouting UHPC; a joint is reserved between the pile prefabricated raft plate block and the pile-free prefabricated raft plate block, a rabbet which moves upwards and backwards is formed in the periphery adjacent to the joint, and a full-length extending steel plate is pre-embedded in the lower portion of the rabbet and is connected with raft plate structural steel bars through the full-length pre-embedded steel plate; and short steel bars are welded to the top faces of the full-length extending steel plates at intervals, and post-pouring UHPC is poured into the joints. The precast concrete technology is fully utilized, the connecting structure can release raft arch-up stress and deformation caused by underground water buoyancy, and a piled raft foundation solution which is reliable in quality, easy and convenient to construct and excellent in performance is formed.
本发明公开了一种装配式抗浮桩筏基础，属于建筑基础技术领域。其包括有桩预制筏板块、无桩预制筏板块和预制预应力管桩；有桩预制筏板块在预制预应力管桩部位设置预留孔，预留孔内设置UHPC十字交叉支撑；预制预应力管桩顶部设置连接钢筋和钢托板，与有桩预制筏板块通过灌芯UHPC连接；有桩预制筏板块和无桩预制筏板块之间预留接缝，与接缝相邻的周边设置上进下退的企口，企口下部预埋通长伸出钢板，通长伸出钢板通过通长预埋钢板和筏板结构钢筋连接；在通长伸出钢板顶面间隔焊接短钢筋，向接缝内浇筑后浇UHPC。本发明充分利用预制混凝土技术，连接构造可释放地下水浮力引起的筏板上拱应力及变形，形成质量可靠、施工简便、性能优良的桩筏基础解决方案。
