高速铁路隧道接触网轨槽预埋施工技术

Track Groove-Pre-Burying Techniques for the Contact Net of the Tunnel for High-Speed Railways

近年来高速铁路隧道接触网工程数量不断增加,结合兰新铁路客运专线某标段工程,具体介绍了隧道接触网轨槽预埋施工的工艺流程、质量控制标准、注意事项,定位孔的开设、轨槽定位、施工中对轨槽的检查和保护等,有效确保了高速铁路隧道接触网轨槽预埋施工质量。

In recent years？ the number of the contact net projects for high speed railway tunnels is increased continuously. With the project of a certain contracted section of the passengers-oriented railway of the Lan-Xin Railway as a practical example？the process flow of pre-burying the track grooves for the tunnel contact net？the quality controlstandards？points for attention,the laying of the location holes？the locating of the track grooves？and the inspection and safeguardingthe track grooves in the course of construction are introduced in detail in the paper. All those technical measures helpensure the construction quality of pre-burying the track grooves of the tunnel contact net of high speed railways.
