预应力混凝土简支箱梁施工技术

Construction Technology of Prestressed Concrete Simply-Supported Box Girder

结合某简支箱梁施工实例,详细地探讨了简支箱梁施工中的支架预压及模板调整、钢筋及钢绞线加工与安装、混凝土浇筑、预应力施工及真空注浆等施工环节,总结了切实可行的施工技术,可为同类工程提供参考借鉴。

Combined with the construction example of one simply supported box girder, the paper discusses the construction link from the aspects such as support preloading and template adjustment, installation of concrete iron and steel strand, concrete pouring, prestress construction, vacuum grouting, and so on, and summarizes the feasible construction technology , which can provide reference for the similar engineering.
