Self-resetting prefabricated assembled pier and construction method thereof
The invention relates to the technical field of bridge engineering, and discloses a self-resetting prefabricated assembled pier and a construction method thereof. The self-resetting prefabricated assembled pier comprises a prefabricated pier column and a foundation platform and further comprises prestressed tendons and energy dissipation connecting pieces; the prefabricated pier column and the foundation platform are connected into a whole through the prestressed tendons, one end of each prestressed tendon is used for anchoring a carrying structure at the top of the prefabricated pier column,and the other end anchors the foundation platform. The energy dissipation connecting pieces are connected with the bottoms of the prefabricated pier columns and the foundation platform. The assembledpier is simple in structure, convenient to operate and high in construction efficiency, the constructed assembled pier has self-resetting performance and good overturning resistance, the problem thatpier corner parts of existing assembled piers are prone to damage and breakage due to stress concentration is effectively solved, and the damaged parts are easy to repair.
本发明涉及桥梁工程技术领域，公开了一种自复位预制拼装桥墩及其施工方法，该自复位预制拼装桥墩包括预制墩柱与基础承台，还包括预应力筋和耗能连接件；预制墩柱与基础承台通过预应力筋连接形成整体，预应力筋的一端用于锚固预制墩柱顶部的搭载结构，另一端锚固基础承台；耗能连接件连接预制墩柱的底部与基础承台；本发明结构简单、操作便捷，施工效率高，施工完成的拼装桥墩具有自复位性，抗倾覆性好，有效解决了现有的拼装桥墩的墩角部位容易因应力集中而损伤破碎的问题，并易于对破损的部位进行修复。
