Railway track-laying system in tunnel - forms floor with same transverse inclination as track

摘要

The railway track-laying system in a tunnel is particularly for very high-speed trains, a section of track with concrete sleepers, preferably pre-stressed, being aligned in the vertical and horizontal directions in a trough in relation to the tunnel floor, and grouted in with concrete poured on site. The tunnel floor surface (4) at the track is formed with the same transverse inclination as the track and at a constant height (h) below the rail of the track at a small distance from the sleeper ends. The grout (13) securing the sleepers (9) is poured onto the floor. ADVANTAGE - Economy of material.
