超长混凝土结构加强带在地铁施工中的应用

The application of extra long concrete structure reinforcing band in subway construction

通过对超长混凝土结构传统后浇带施工中混凝土自应力的分析,指出采用膨胀加强带代替传统后浇带可实现无缝施工,解决了开裂、渗漏等质量问题,大大缩短了施工周期,具有一定的推广价值。

Through concrete self stress analysis of extra long concrete structure classic late poured band construction, it pointed that the expansive reinforce concrete tape replaced classic late poured band could realize no-seam construction, which resolved cracking, leakage and other quality problems, and shortened construction period, had some popularized value.
