Pushing, transverse moving, splicing and mounting method for steel structure bridge
The invention relates to the technical field of steel structure bridges, in particular to a pushing, transverse moving, splicing and mounting method for a steel structure bridge, which comprises the following steps: S1, building a prefabricated frame bridge site at a proper position on the side of a bridge head, building a steel beam splicing site on the prefabricated frame bridge site, and constructing a sliding plate on one side of the steel beam splicing site, constructing the pushing plates at the ends of the sliding plates, and prefabricating frame bridge sections on the sliding plates; and S2, prefabricating the frame bridge sections on the sliding plates: specifically, the steel beam sections are spliced in the longitudinal direction to form steel beam units in a steel beam splicing site. Compared with a traditional pushing mode, the pushing, transverse moving, splicing and mounting method for the steel structure bridge can effectively reduce horizontal pushing force borne by buttresses, the bridge structure stress is improved, the overall stability and local stability requirements during bridge pushing construction are greatly guaranteed, the method can be applied to the construction process of bridges with complex linearity, and the method has wide applicability.
本发明涉及钢结构桥梁技术领域，尤其涉及一种钢结构桥梁的顶推横移拼接安装方法，包括以下步骤：S1、在桥头侧方合适位置建造预制框架桥场地，并在预制框架桥场地上建造钢梁拼接场地，在钢梁拼接场地一侧施工滑板，在滑板的端部施工顶推板，并在滑板上预制框架桥节段；S2、在滑板上预制框架桥节段：在钢梁拼接场地由钢梁节段沿纵向拼接形成钢梁单元，本发明作为一种钢结构桥梁的顶推横移拼接安装方法，较传统顶推方式而言，能有效减小支墩所受的水平推力，改善桥梁结构受力，大大保证了桥梁顶推施工时的整体稳定性和局部稳定性要求，此方法可以应用在具有复杂线性的桥梁的建设施工过程，使本发明的方法具有广泛的适用性。
