跨包西铁路特大桥变截面薄壁空心墩翻模施工技术
|
摘要
随着国家铁路规模的迅猛发展,铁路桥梁的薄壁空心墩技术的应用也越来越多。本文结合蒙华铁路跨包西铁路特大桥16#～17#变截面空心薄壁墩施工实践,叙述了邻近既有线变截面空心薄壁墩施工方案的选择及施工工艺、质量、安全控制措施,为今后同类工程的施工提供参考,具有较广泛的推广价值。
With the rapid development of the national railway scale,the thin-walled hollow piers technology in railway bridges is often used. Combined with the construction practice of No. 16 ～ 17 variable cross-section thin-walled hollow pier across over Baotou-Xi'an Railway Bridge in Inner Mongolia-Jiangxi Railway,the paper describes the construction scheme selection on hollow thin-walled pier with variable cross-section adjacent to the existing line,as well as its construction technology,quality and safety control measures. It could provide a reference with a widely spreading value for similar projects in the future.
