多重防水技术在长大框架桥施工中的应用

Application of Multiple Waterproofing Technology in Big Frame Bridge Construction

苏州人民路公铁框架桥工程中,主体框架处在承载力低、渗水性强的地质漏斗区域,必须做好防水工作,确保结构不漏水。坚持"以防为主、刚柔结合、多道防线、因地制宜、综合治理"的施工原则,总结了从外到内、从下至上的多重防水施工技术,为同类工程提供了借鉴。

In the engineering of iron frame bridge in Suzhou people＇s Road, the main framework locates in geological funnel area of the low bearing capacity and strong water permeability. Thus waterproof is required to prevent the structure from water leakage. In line with the-focus on multiple preventions for comprehensive treatment according to practical conditions, the paper summarizes multiple water prevention technology from outside to inside and from top to bottom, and provides the reference for the similar project.
