武广铁路客运专线采用CRTSⅠ型双块式无砟轨道,结合在武广客运专线武汉试验段的施工实践,对施工工艺特别是轨道精确定位方法与控制要点进行分析,指出根据设计线型对轨排上面的钢轨进行精调定位后,再浇筑下面道床板混凝土,可以达到轨道定位一次到位的目的,减少道床板浇筑后的轨道精调作业量,减少精调时间和调整件数量。 Based on the construction practice of Wuhan test section of Wuhan-Guangzhou Passenger Dedicated Railway, this paper analyzes the precise positioning method and control points of the construction technology, especially the orbit, and points out that according to the design of linear orbit Arrangement of the above rails for fine positioning, and then pouring the concrete below the ballast bed can achieve the purpose of positioning the rail once in a row to reduce the rail slab pouring orbit after the fine-tune the homework to reduce the amount of fine-tuning time and adjust the number of pieces.
