深层黄土隧道无砟轨道重建快速施工关键技术

Key Technologies of Rapid Construction of Ballastless Track Reconstruction of Deep Loess Tunnel Ballastless Track

本文通过张家庄隧道无砟道床重建施工实例,介绍了在高铁隧道无砟道床施工中的一些关键技术,如施工准备、物流组织、CPⅢ轨道控制网测设、轨排粗(精)调及混凝土施工等,这些关键技术对高铁隧道抢险工程施工技术具有积极的参考价值。

Through the reconstruction example of the ballastless track in Zhangjiazhuang, this paper introduces some key technologies in the construction of ballastless track in high -speed railway tunnel, such as the construction preparation, logistics organization,measurement and design of CP III track control network, rough adjustment and fine adjustment of track skeleton, concrete construction and so on. These key technologies have a positive reference value for the construction technology of high-speed railway tunnel.
