摘要
当前,随着我国建设领域的快速发展,在拱桥建设方面,钢箱梁安装施工工艺发挥着越来越重要的作用。以引江济淮在庐江县内的罗埠大桥为例,重点介绍了下承式钢管混凝土拱桥在内河流域内钢箱梁施工方法,主要包含钢箱梁安装支架设计、拖拉滑移具体步骤等,为类似工程提供借鉴。
At present,with the rapid development of the construction field in China,the installation and construction technology of steel box girder has been playing an increasingly important role in the construction of arch bridges.Taking the Luobu bridge,which is used to carry the Yangtse river and Huaihe river to Lujiang county,as an example,the construction method of steel box girder for the concrete-filled steel tube arch bridge in the inland river basin is introduced,mainly including the design of steel box girder installation bracket,the concrete steps of dragging and sliding,etc.,so as to provide reference for similar projects.
