Background technique
As the underground traffic of the rapid development of our people's economy, while city is also quickly grown, meeting when train driving
The tail gas containing multiple harmful substances is discharged, is introduced into fresh air from the external world and waters down harmful components in tail gas, make harmful substance
Concentration, which is reduced to safe concentration or less just, seems particularly important, and due to the particularity of Metro Space structure, the ventilation in tunnel is set
Ineffective always, therefore reasonable setting vented exhaust facility is applied, to basis in the life security of support personnel, protection path
Facility and structure are crucial.
Existing patent CN104989420A provides a kind of safety for being easy to discharge fume and is open to traffic tunnel, including the tunnel that is open to traffic, institute
The side for stating the tunnel that is open to traffic is equipped with the discharge flue closed at both ends separated by the first partition wall and the tunnel that is open to traffic, described
It is logical that the inside far from the tunnel that is open to traffic of discharge flue is equipped with the safety separated by the second partition wall and the discharge flue
Road, the escape route for being equipped with both connections between the exit passageway and the tunnel that is open to traffic and being isolated with the discharge flue;
The discharge flue is communicated by crossing the smoke evacuation branch pipe on first wall with the tunnel that is open to traffic, and the discharge flue is logical
It is extraneous to cross smoke explorer connection.The present invention is quickly sucked the smog being open to traffic in tunnel, so on a large scale by setting discharge flue
Row arrives the external world, the significant effect for mist of discharging fume afterwards;Under crisis situations, personnel can enter exit passageway by escape route, guarantee
Human life's safety.But air draft and air inlet are same path in the technology tunnel, easily cause interference, drafting efficiency is low, simultaneously
Flue gas is directly discharged into atmosphere in tunnel, causes influence to environment.
Existing patent CN203925558U provides a kind of short section ventilation smoke exhaust structure of subway, including single partition wall, section
Ventilating shaft and smokejack, the list partition wall are set to the centre at short section parking line, short section are laterally divided into left line section and the right side
