高速铁路的发展证实,高速铁路基础工程如果使用常规的轨道系统,道砟粉化严重,线路维修频繁,安全性、舒适性、经济性相对较差。无砟轨道采用谐振式轨道电路传输特性技术,首次成区段建成无砟轨道铁路。本文根据无砟轨道道床施工要求阐述了无砟轨道基桩控制网的建立,以及CPⅢ控制网建立好后,进行无砟轨道底座的施工,其Ⅰ型板式无砟轨道安装、调整测量和在长钢轨铺设后,安装充填式垫板前进行无砟轨道线路精测、定位测量方法与无砟轨道施工技术。
The development of high-speed railway confirms that if the conventional high-speed railway infrastructure is used, the severe dusting of the road surface will lead to frequent maintenance of the lines, resulting in relatively poor safety, comfort and economy. Ballastless track using resonant orbit transmission characteristics of the technology, the first section into a ballastless track railway. Based on the ballastless track ballast construction requirements, the article sets forth the establishment of ballastless track foundation pile control net and the construction of ballastless track base after the CPⅢ control network is established. The first type slab ballastless track is installed, adjusted and measured at long After the laying of the rail, before installing the filling plate precision measurement of ballastless track line, positioning measurement methods and ballastless track construction technology.
