Fabricated replaceable combined pier after earthquake
The invention relates to the field of piers, in particular to a fabricated replaceable combined pier after an earthquake. The bridge pier comprises a lower bridge pier structure and an upper bridge pier structure which are sequentially arranged from bottom to top, and the lower bridge pier structure is detachably connected to the lower end of the upper bridge pier structure. During actual use of the pier, the upper portion of the pier is connected with the bridge body, and the lower portion of the pier is fixed to the ground. When an earthquake occurs, the damaged position of the bridge pier is mainly concentrated on the lower portion of the bridge pier. Therefore, the bridge pier is designed into the upper bridge pier structure located on the upper portion of the bridge pier and the lowerbridge pier structure located on the lower portion of the bridge pier, and detachable connection is formed between the upper bridge pier structure and the lower bridge pier structure. When the lowerbridge pier structure is damaged, only the lower bridge pier structure needs to be replaced and the upper bridge pier structure needs to be reserved during maintenance, and maintenance difficulty andmaintenance cost are reduced. And the upper pier structure is reserved during maintenance, so that the main beam connected with the upper pier structure cannot be damaged due to maintenance, and the safety of maintenance personnel can be guaranteed.
本发明涉及桥墩领域，具体是涉及一种装配式震后可更换组合桥墩。包括从下至上依次设置的下桥墩结构和上桥墩结构，所述下桥墩结构可拆卸式连接在上桥墩结构的下端。桥墩在实际使用时，桥墩的上部与桥梁主体相连接，桥墩的下部固定在地面上。当地震发生时，桥墩被破坏的位置主要集中在桥墩的下部。因此，本发明将桥墩设计成位于桥墩上部的上桥墩结构和位于桥墩下部的下桥墩结构，且上桥墩结构和下桥墩结构之间构成可拆卸连接。当下桥墩结构被损坏，维修时只需要更换下桥墩结构而保留上桥墩结构，降低了维修难度和维修成本。而且维修时保留上桥墩结构，既不会因维修而破坏与上桥墩结构相连接的主梁，又能够保障维修人员的安全。
