TRANSVERSE VENTILATION OF DOUBLE TUBE TUNNELS USING AN AUXILIARY TUNNEL

A transverse ventilation system proposed for double tube tunnels uses an auxiliary gallery. With this system complete separation is attained between fresh air ducts (in the auxiliary gallery) and used air ducts over the main tunnels ceiling. The proposed system makes it possible to reduce the cross-section of the fresh air supply ducts, by using a contemporaneity factor of the peak traffic flows in the two tubes. A further advantage is the reduction of construction problems and the solution of safety problems.
