无砟轨道是具有“高精度、高平顺性、耐久性”结构特点的综合性和系统性非常强的工程,对精度的要求非常高。论文重点探讨了双块式无砟道床关键施工工艺、轨道状态检测、轨道测量、模拟试算、调整件准备、轨道调整、调整方法、质量控制、轨道静态调整标准、轨道状态复测、安全管理,注意事项等内容。针对双块式无砟道床精调施工方法进行一系列详细论述,为双块式无砟道床静态调整施工提供参考。 Ballastless track is a comprehensive and systematic very strong engineering with “high precision, high ride comfort,” structural features, the requirements of the accuracy is very high. The paper focuses on the key construction technology of double-block ballastless bed, track condition test, orbit measurement, simulation test, adjustment part preparation, track adjustment, adjustment method, quality control, track static adjustment standard, track state retest, safety management , Matters needing attention and so on. A series of detailed discussion is made on the fine adjustment method of double-block non-ballast bed, which provides a reference for the static adjustment of double-block ballastless bed.
