一次性浇筑地铁长轨枕双侧沟式整体道床技术应用

The Application of One-time Concreting Technology for Subway Long Sleeper Bilateral Groove Type Monolithic Roadbed

地铁轨道道床浇筑混凝土时,水沟里的水容易通过水沟和道床两次浇筑混凝土的接触缝进入道床,对道床产生破坏,以致使道床混凝土松动,直接影响地铁线路的稳定。详细探讨了一次性浇筑地铁长轨枕双侧沟式整体道床技术的应用。

In concreting for subway track＇s roadbed, the water in the ditch will easily contact joints between the ditch and roadbed in two-times concreting, which will cause the enter the damage roadbed through the to the roadbed, make the roadbed concrete loose, and directly influence the stability of the subway lines. This paper probes into the application of one-time concreting technology for subway long sleeper bilateral groove type monolithic roadbed.
