The parallel pilot tunnel in this section of hole is vertically separated into superposed longitudinal ventilation road and positioned at the fire escape of lower part by vertical baffle,
Transverse passage-way is connected with fire escape；The longitudinal baffle of fire escape is closed downwards in the distal end setting of the vertical baffle, vertical
Full face longitudinal ventilation road is formed between partition board pilot tunnel parallel with hole distal end；The distal end setting of the parallel pilot tunnel in the hole
The transversal ventilation road being connected with left side tunnel or right side tunnel；Setting smoke evacuation jet blower, evacuation in the longitudinal ventilation road
Smoke prevention jet blower is set in channel.
The invention has the advantages that forming independent fire escape and longitudinal ventilation by separating the parallel pilot tunnel in hole
Road, and the transversal ventilation road being connected with left side tunnel or right side tunnel is set in the distal end of the parallel pilot tunnel in hole, longitudinally logical
Smoke evacuation jet blower, Smoke prevention jet blower are respectively set in air duct, fire escape, makes logical in rescue station tunnel and at protective door
Wind velocity meets requirement of taking precautions against natural calamities, and realizes signs of human habitation separation, ensures the safety of evacuating personnel；It avoids and jet blower is mounted on a left side
It adversely affects, eliminates safe hidden trouble caused by high speed train safety in side tunnel, right side tunnel main tunnel；Be independently arranged
Ventilating duct is compared, and ventilating duct is arranged by the way of extending pilot tunnel parallel with partition evacuation, quantities is smaller, and project cost is more
It is low.
The present invention is suitable for various extra-long railway tunnel groups.
