Lifting shape control construction method for large-span continuous steel box girder bridge
The invention discloses a lifting shape control construction method of a large-span continuous steel box girder bridge, which relates to the field of municipal bridge construction and comprises the steps of steel box girder segmentation, stress deformation analysis, pre-assembly, cross beam erection and tensile embedded part connection, ground splicing and erection, lifting truss installation and lifting, lifting truss and equipment dismantling and the like. The midspan of the steel box girder is lifted through the lifting equipment, alignment, temporary fixing, correction and full-length welding of the inner arc section steel box girder and the outer arc section steel box girder are achieved, on the premise that construction safety and quality are guaranteed, deformation of the steel box girder and the influence on a lower road network after temporary supporting is canceled are reduced, local deformation of the steel box girder after the steel box girder is in place is controlled, and the construction efficiency is improved. And the construction safety and quality are improved.
本申请公开了一种大跨度连续钢箱梁桥的提拉控形施工方法，涉及市政桥梁建造的领域，其包括钢箱梁分段、应力变形分析、预拼装、横梁架设及抗拉埋件连接、地面拼接与架设、提拉桁架安装及提拉，以及提拉桁架与设备拆除等步骤。本申请利用提拉设备对钢箱梁跨中进行提拉，实现内外弧段钢箱梁的对齐、临时固定、校正及满焊焊接，在保证施工安全及质量的前提下，减小钢箱梁的形变以及取消临时支撑后对下部路网的影响，控制钢箱梁就位后的局部变形，提高施工安全性及质量。
