Bridge abutment structure with replaceable back wall and construction method
The abutment structure comprises the abutment back wall and an abutment body, the abutment body comprises a bearing platform and a pile foundation, the pile foundation is located below the bearing platform and used for supporting the bearing platform, background filling is arranged on one side of the abutment back wall, the abutment back wall is an independent prefabricated part, and the abutment back wall is fixed to the bearing platform through a connecting part. Mounting parts for mounting the connecting parts are arranged on the abutment back wall and the supporting bearing platform; when the earthquake force exceeds a set value, the connecting part is damaged by the earthquake force; the bridge abutment back wall is a prefabricated part, connection between the bridge abutment back wall and the bridge abutment bearing platform can be achieved through the shear bars and the bolts, and compared with the mode that the bridge abutment back wall and the bridge abutment bearing platform are integrally formed in the prior art, fabricated construction is facilitated, back wall sections damaged after an earthquake can be rapidly replaced, and rapid repairing of the bridge abutment after the earthquake can be achieved; and precious time is won for post-disaster rescue, and the post-earthquake bridge repair and traffic recovery efficiency is improved.
本发明公开一种可更换背墙的桥台结构及施工方法，包括桥台背墙及台身，台身包括承台及桩基，桩基位于承台下面用于支撑承台，桥台背墙一侧为后台填土，所述桥台背墙是独立的预制构件，桥台背墙通过连接部固定在承台上，桥台背墙及支撑承台上设置有安装所述连接部的安装部；当地震力超过设定值时，所述的连接部被地震力损坏；本发明桥台背墙为预制构件，通过剪力棒及螺栓可实现桥台背墙与桥台承台的连接，与现有技术桥台背墙与桥台承台一体成型的方式相比，本发明便于装配化施工，地震破坏后的背墙节段可快速进行更换，可实现震后桥台快速修复，为灾后救援争取了宝贵时间，提高了震后桥梁修复和交通恢复效率。
