在高速公路和城市建设中,桥梁结构施工占据着至关重要的位置。本文以广乐高速公路第T22合同段箱梁预制项目为例,对箱梁预制及安装施工技术进行探讨,分别阐述了台座施工,钢筋加工,预应力张拉,孔道压浆等关键工序施工步骤及注意事项。 In the highway and urban construction, the construction of the bridge occupies a crucial position. Taking the prefabricated box beam prefabricated project of section T22 of Guangle Expressway as an example, this paper discusses the prefabrication and installation of box girder construction technology, and respectively elaborates the construction steps of pedestal construction, steel bar processing, prestressing tensioning and pore pressure grouting And precautions.
