Vertical continuous segmental prefabricated assembled bridge pier with tenon-and-mortise structure
The invention relates to the technical field of bridge engineering, and discloses a vertical continuous segmental prefabricated assembled bridge pier with a mortise and tenon joint structure. Thevertical continuous segmental prefabricated assembled bridge pier comprises a bottom bearing platform, a prefabricated segmental assembled bridge pier with a dovetail joint structure, a prefabricated bent cap, a connecting bearing platform, vertical continuous steel bars of prefabricated segments and the bent cap, an external prestressing anchoring system for connecting the bearing platform, the prefabricated sections and the bent cap, and a dovetail tenon structure. Compared with a traditional integral type bridge pier, the bridge pier is subjected to segment prefabrication production in a factory, the use amount of bridge pier concrete is reduced, the hoisting mass during assembly is reduced, the bottom segment plastic hinge can be poured through UHPC, the mechanical property of the structure is improved, the dovetail tenon connecting mode is introduced between the assembly segments, the lateral shear resistance of the lateral bridge pier is improved, and meanwhile the anti-roll capacity and the self-resetting capacity of the segment prefabricated and assembled bridge pier are improved.
本发明涉及桥梁工程技术领域，且公开了一种竖向连续带榫卯结构的节段预制拼装桥墩，包括底承台，带有燕尾榫结构的预制节段拼装桥墩，预制盖梁，连接承台、预制节段以及盖梁的竖向连续钢筋，连接承台、预制节段以及盖梁的体外预应力锚固系统以及燕尾榫结构。与传统的整体式桥墩相比，本发明通过在工厂将桥墩进行节段预制生产，降低了桥墩混凝土的用量，减轻拼装时吊装的质量，并且可以将底节段塑性铰去采用UHPC进行浇筑，提高结构的力学性能，通过将燕尾榫的连接形式引入到拼装节段间，提高了侧向桥墩的侧向抗剪能力，同时提高节段预制拼装桥墩的抗侧倾能力、自复位能力。
