摘要

湄渝高速跨沈海高速现浇梁工程施工,是跨既有分离式双向八车道的大跨度现浇梁支架的施工,取得了较大的安全效益、社会效益和经济效益。基此,文章详细阐述了大跨度支架设计与搭设、沈海高速桥梁两侧支架搭设处理、非标贝雷梁的应用、双层贝雷梁安装和拆除等施工技术及措施。
        The cast-in-situ beam construction of Meiyu Expressway across Shenhai Expressway is the construction of large-span cast-in-situ beam bracket spanning the existing separated two-way eight lanes,which has achieved greater safety,social and economic benefits. Based on this,this paper elaborates on the design and erection of long-span brackets,the erection and treatment of brackets on both sides of Shenhai high-speed bridge,the application of non-standard Bailey beams,the installation and demolition of double-deck Bailey beams and other construction technologies and measures.
