Bridge pier replacing method
The invention discloses a bridge pier replacing method, which is used for replacing an existing bright pier with a temporary bridge pier, and comprises the following steps: arranging a temporary bridge pier on the bottom side of a bridge; arranging a baffle on an existing bridge pier and/or the temporary bridge pier and making the baffle contact with the side wall of the bridge; arranging a jacking mechanism between the existing bridge pier and the bridge and/or between the temporary bridge pier and the bridge; driving the bridge by the jacking mechanism to move away from the existing bridge pier, so that the connection relation between the bridge and the existing bridge pier is relieved; and driving the bridge by the jacking mechanism to move towards the temporary bridge pier, so that the bridge is supported by the temporary bridge pier. According to the technical scheme, the technical problems that in the prior art, when piers are replaced, an overpass can move transversely, and safety is low are solved.
本发明公开一种桥梁换墩方法，以将所述桥梁的既有桥墩托换为临时桥墩，包括：将所述临时桥墩设置于所述桥梁的底侧；将挡板设置于所述既有桥墩和/或临时桥墩，并接触所述桥梁的侧壁；将顶升机构设置于所述既有桥墩与所述桥梁之间和/或所述临时桥墩与所述桥梁之间；通过所述顶升机构驱动所述桥梁背离所述既有桥墩移动，以解除所述桥梁与所述既有桥墩的连接关系；通过所述顶升机构驱动所述桥梁朝向所述临时桥墩移动，以使得所述临时桥墩支撑所述桥梁。本发明技术方案旨在解决现有技术中在换墩之时，立交桥具有横向移动，安全性低的技术问题。
