摘要
结合淅河桥工程实际,从施工准备、模板和钢筋制作安装、预应力钢筋张拉、混凝土浇筑与养护、预应力钢筋放张和后期养护等方面分析了先张法预应力混凝土空心板梁施工工艺与方法,为预应力混凝土工程施工技术发展提供了参考价值。
This paper analyzed the construction technology and method of the pretensioned prestressed concrete hollow slab for example Xihe bridge,from the construction preparation,formwork and steel bar installation,prestressed steel bar tensioning,concrete pouring and maintenance,prestressed steel bar release and post-conservation. It provides reference value for the development of prestressed concrete engineering construction technology.
