摘要
以沪昆客专新吉坪隧道接触网槽道施工为例,介绍接触网槽道预埋施工技术,即采用槽道组焊定位模具及槽道二次定位施工技术,确保了槽道预埋的精度,为今后高铁或客专隧道的接触网槽道施工提供参考。
With the construction of the channel for the contact net of the Xinjiping Tunnel of the Shanghai-Kunming Passenger- oriented Railway as a practical example,the construction techniques of embedding channels in advance for the contact net are in-troduced in the paper,namely, the technique of adopting the positioning moulds for the assembly welding of the channel,and the construction technique of the second-time positioning, both of which help ensure the embedding accuracy of the channel. The project may serve as a useful reference for the construction of other channels for the contact net of the tunnels of either high-speed railways or passenger-orented railways in the future.
