Hoisting construction method for lower steel pier of existing bridge
The invention discloses a hoisting construction method for a lower steel pier of 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, hoisting a steel cantilever arm, grouting the steel pier and installing a bridge floor accessory structure. Compared with the prior art, the method has the advantages that the steel pier is reasonably segmented, the balancing weights are arranged on the outer sides of the steel cantilevers, the gravity center of the steel pier is moved out of the existing bridge, construction of the steel pier of the spliced wide bridge under the existing bridge is smoothly achieved, and the method is convenient to construct, low in cost, safe, effective 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吊装施工方法，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，钢挑臂吊装，钢桥墩灌浆，桥面附属结构安装。与现有技术相比，本方法通过对钢桥墩合理分段，在钢挑臂外侧设置配重块的方法，使其重心外移至既有桥梁之外，顺利实现既有桥梁下的拼宽桥钢桥墩施工，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。
