This paper takes Xiamen Airport highway tunnel as an example, considering four different construction steps during small spacing tunnel construction. Made of cast iron, it was known as Wilson's Patented Stone-Cutting Machine, after its inventor Charles Wilson. Welding, coating, and wrapping 8. In the urban areas the level crossing are generally monitored by qualified railway personnel who monitor the train movement and close the level crossing When the buildings are near to the subway line, communications channels could be con- structed as a junction between the subway and the buildings. Organize the projects so that the money goes to the right place. Domestic Scan, National Cooperative Highway Research Program. PROCEDURES OF PLANNING AND CONSTRUCTION 3. SPECIAL NOTE: … procedure for tunnels, as compared to aboveground structures, is much more dependent on such factors as the site situation, the ground characteristics, and the excavation and support methods used. Page 5 - Tunnel ou pont ? The small spacing tunnel is a kind of tunnel structural style which situates between ordinary tunnel and double-arch tunnel. 1. Page 6 - Un tunnel oui, mais comment ? Initial support during construction and final support during the functional life of the tunnel pose separate requirements; sometimes both are best satisfied by a single support system. Page 9 - Confort = Anti inconvénients. Each of these tunnels is served by a construction railway which is used to transport personnel, equipment and materials into and out of the tunnel. River crossing 7. They might be bodies of water, mountains or other transportation routes.
