地铁桥梁工程中的支架法现浇箱梁施工技术

Construction Technology of Cast-in-Place Box Girder with Support Method in Subway Bridge Engineering

支架法现浇箱梁凭借施工便捷、安全可靠、成型质量良好等优点,被广泛地应用于地铁桥梁工程的各施工现场。以深圳市城市轨道交通6号线长圳站-观光站工程为背景,重点围绕支架法现浇箱梁的施工技术展开探讨,阐述施工中的技术要点,包括支架安装、预压、梁体施工、螺旋管支架施工等内容,可为类似工程提供参考。

With the advantages of convenient construction,safe and reliable construction and good forming quality,bracket method has been widely used in the construction sites of subway bridge engineering.Based on Shenzhen urban rail transit line 6 Changshen station to Guanguang station engineering as the background,this paper focuses on the construction technology of cast-in-place box girder with support method,and elaborates the technical points in the construction,including support installation,preloading,beam construction,spiral pipe support construction,etc.,which ultimately ensures the overall quality of the project.
