摘要
文章针对CRTSⅠ型双块式无砟轨道施工中的常见问题,结合高速铁路具体施工实践,从上线施工准备、道床板施工精度控制、底座板及道床板裂纹控制、道床板离缝控制等方面,讨论了影响双块式无砟轨道的施工质量的常见问题,并针对性地提出了解决措施。应用结果表明,标准化、系统化的质量控制可有效降低CRTSI型双块式无砟轨道施工中的常见、易发质量问题,为类似工程实践提供了重要参考。
Aiming at common problems during construction of CRTSⅠ twin-block ballastless track, combined with the specific construction practices of high-speed railway, the common problems affecting the construction quality of the twin-block ballastless track are discussed from the aspects of on-line construction preparation, precision control of track bed slab construction, crack control of base and track bed slabs, and control of slab seam, and the specific solutions are put forward. The application results of those solutions show that standardized and systematic quality control can effectively reduce common and prone quality problems during construction of CRTSⅠ twin-block ballastless track, and can provide important references for related engineering practices.
