FIELD: construction.
SUBSTANCE: invention relates to the ventilation of transport tunnels, namely to the method of removal of radon in railway tunnels. This includes the movement of streams of air under action of a moving electric locomotive. Before entering the tunnel on the electric locomotive flaps open and create strengthening to the pressure of streams of air, they will carry radon from stagnant zones of sewage chutes, mix it in a turbulent stream of air and ejected through existing ventilating system, after passage of the tunnel flaps on an electric locomotive are clean.
EFFECT: ensures a sufficient yield force of the pressure of air streams for removal of radon from sewage chutes of a tunnel.
