膨胀加强带代替后浇带在超长混凝土结构施工中的应用

The Application of Expansion Reinforcing Strip Instead of Back Strip Used in the Overlong Concrete Structure Construction

文章以京沪高铁南京南站北广场工程为例,针对传统后浇带施工中存在的一系列问题,对膨胀加强带代替后浇带的基本原理及施工工艺作了论述,阐明超长混凝土结构采用膨胀加强带是一项有效加快工程进度和降低施工成本的技术措施。

Based on the project from north square, Nanjing south railway station, Beijing-Shanghai high-speed rail line, and according to a series of problems of traditional back strip in the construction, discuss the basic principle and construction technology used by expansion reinforcing strip instead of back strip, illustrate that it is technical measures to speed up the construction progress and reduce the construction cost used by expansion reinforcing strip.
