Technical field
The present invention relates to ventilating apparatus for tunnels technical field, specially a kind of ventilative metope structure of subway tunnel smoke evacuation.
Background technology
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, being introduced into fresh air from the external world waters down harmful components in tail gas, makes 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 rational 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 being easy to smoke evacuation 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 with the tunnel that is open to traffic by the first partition wall, 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 escape way 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 the way that discharge flue is arranged
Row arrives the external world, the significant effect for mist of discharging fume afterwards；Under crisis situations, personnel can enter escape way by escape route, ensure
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 air in tunnel, and influence is caused on 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
Line section, section ventilating shaft are set to the middle part in short section, ventilating apparatus for tunnels are equipped in the ventilating shaft of section；Left line section and right line section
Top be respectively equipped with a smokejack, each smokejack respectively with the previous station right end in short section and latter station left end
Heat extraction wind devices are connected to the ventilating apparatus for tunnels by getting in touch with air duct by getting in touch with air duct connection, the smokejack.On a left side
Smokejack is arranged in the top in line section and right line section, and section fire scenario is reduced to one kind.The short section ventilation row of subway
Section fire scenario is divided more succinct, smoke evacuation effect by cigarette structure in the case where not influencing normal running tunnel, Fire Ventilation
Fruit is preferable.But the engineering amount is larger, and cost is higher, and design is relatively complicated.
