ring under Gagarin square –The Gagarin tunnel. The twin

tunnel is 1100 m long and 20 m wide.
The twin tubes are divided by a solid barrier, admissible traffic speed is 100 km/h in the undersurface part.

= 0.019m with the North-South direction and the form of

tunnel   on all of the terrace is rectangle.

The terrace passes almost parallel the existing pipeline (at a distance of 25 m) laid in technological tunnel №-1 which was built in the1970.

The main parameters of the ventilation system in this project provide the necessary ventilation tunnel by using natural draft factor for minimally open the part of tunnel section 15.73 and taking into account the internal space of the tunnel blockage process piping, cable seals, monitoring equipment and ensure safe operation.
