轨排架法施工无砟轨道精调测量技术

On precisely-adjusting survey of unballasted tracks of track bent method construction

结合龙厦铁路象山隧道无砟轨道施工,论述了使用自动跟踪全站仪、自动记录整理轨道各项参数的轻型轨检小车对轨排架法施工的双块式无砟轨道精调的测量技术,以确保轨道的平顺性,提高无砟轨道的建设质量。

Combining with the unballasted tracks of Xiangshan tunnel of Longyan-Xiamen railway,the paper indicates the precisely-adjusting survey technique of double-block unballasted track of the track bent method construction by using the automatic tracking total station and the light track inspection vehicle with the function of the automatic recording and compiling all parameter,so as to ensure the smoothness of the track and enhance the constructing quality of the unballasted tracks.
