摘要
文章以冷水江资江二桥为例,针对宽翼宽幅π型主梁悬浇挂篮设计与施工技术特点,提出了分层滑移概念,采用先挂篮结构再内模体系的异步前移方式,既减轻挂篮自重,又方便内模施工,供同类工程参考。
With Lengshuijiang Zijiang II Bridge as an example, regarding the characteristics of cantile- ver-grouting cradle design and construction technology for wide-flange and wide-width -type main girder, this article proposed the concept of layered slipping, and used the asynchronous forward mode of cradle structure first and then internal mold system, which can both reduce the hanging basket weight and facilitate the internal mold construction, thereby providing the reference for similar engineering.
