The invention discloses a translation construction method for a steel pier under an existing bridge, which relates to the technical field of bridge construction and comprises the following steps: surveying the existing bridge, constructing a bearing platform, manufacturing the steel pier in sections, hoisting a steel upright post, installing a steel cantilever transportation platform, hoisting a steel cantilever to the transportation platform, translating the steel cantilever to an installation position, and grouting the steel pier. And mounting a bridge floor accessory structure. Compared with the prior art, the method has the advantages that the steel cantilever adopts an installation construction method of erecting a steel pipe buttress transportation platform and transporting the steel cantilever from the outside of the old bridge to the design position of the pier of the spliced and widened bridge through the electric transportation flatcar, so that the steel cantilever can be installed without hoisting, and the method has the remarkable advantages of convenience in construction, low cost, safety, effectiveness and the like; the problem that the piers of an existing spliced bridge can only be built outside the projection of the existing bridge is solved.
本发明公开了一种既有桥梁下钢桥墩平移施工方法，涉及桥梁施工技术领域，包括如下步骤：既有桥梁进行勘测，承台施工，钢桥墩分段制造，钢立柱吊装，钢挑臂运输平台安装，钢挑臂吊装至运输平台，钢挑臂平移至安装位置，钢桥墩灌浆，桥面附属结构安装。与现有技术相比，本方法中钢挑臂则采用搭设钢管支墩运输平台，通过电动运输平车将钢挑臂从老桥外运至拼宽桥桥墩设计位置的安装施工方法，使其无需吊装即可安装，具有施工方便，成本低廉，安全有效等显著优点，解决了现有拼宽桥只能将桥墩建在现有桥梁投影外的问题。
