Description
Technical field
The utility model patent is related to Long Traffic Tunnels smoke controlling device systems technical field, belongs to a kind of long big traffic
Tunnel area manifold type smoke control system.
Background technology
Long Traffic Tunnels refer to that length of tunnel is longer, and the vehicle run in tunnel can be under the commander of related system
Orderly traveling.It is main to include the automatic conveying traffic that conveyer belt conveyer has been laid in urban track traffic major long tunnel and tunnel
System tunnel.
There are multiple row vehicles simultaneously in the tunnel the case where orderly function in Long Traffic Tunnels peak period in long term.
Currently, domestic Long Traffic Tunnels civil engineering scheme mainly has two kinds of " one-tunnel one-track " and " one-tunnel two-tracks ", to ensure
Effectively smoke evacuation and evacuating personnel, smoke control system are native for both the above when vehicle fire accident in Long Traffic Tunnels
The scheme of " setting section ventilating shaft " and " setting tunnel top civil engineering air duct " is respectively adopted in the scheme of building：
1. section ventilating shaft scheme is arranged：
(1) " one-tunnel one-track " tunnel：Refer to that the uplink and downlink running tunnel that vehicle is run is made of two independent tunnels,
It is arranged the service channel of two tunnel unicom at a certain distance in tunnel at one.
(2) section ventilating shaft：It is arranged in the middle part of tunnel, is made of reversible emergency fan group, air-valve, silencer, air duct etc.,
The unit of mechanical smoke extraction can be carried out to uplink and downlink running tunnel respectively.
(3) operation principle：" one-tunnel one-track " tunnel is separated into several sections by section ventilating shaft, ensures to only exist one in each section
Train of vehicles is run.It is reversible in the section ventilating shaft at fiery vehicle fire position when in tunnel fire incident occurs for vehicle
Turn emergency fan group tunnel between ignition zone to discharge fume, ensures effectively to exclude flue gas, be formed with and evacuate conducive to fire vehicle crew
Air-flow, while ensureing that flue gas does not interfere with the vehicle that do not catch fire in same tunnel.
(4) there are problems：Section ventilating shaft is set in the middle part of running tunnel, big, the civil construction difficulty to ground influence of city layout
Greatly, civil engineering and equipment investment are high.General each section ventilating shaft only Civil Cost is as high as 1000~15,000,000 yuan, and ventilating shaft goes out ground
Partial Coordination by planning difficulty is very big, only can not all be solved by increasing investment sometimes.In addition rivers are crossed in Long Traffic Tunnels
When the sea of lake, there are no condition setting section ventilating shafts on the water surface.
2. tunnel top civil engineering air duct scheme is arranged：
(1) " one-tunnel two-tracks " tunnel：Refer to that the uplink and downlink section that vehicle is run is made of a tunnel, by tunnel
Between the partition wall that is arranged the uplink and downlink running tunnel that vehicle is run is separated, on partition wall every a certain distance be arranged by it is upper,
The fire resistant doorsets of downlink interval tunnel unicom.
(2) tunnel top civil engineering air duct：Using space bigger at the top of Long Traffic Tunnels, one civil engineering air duct is set,
Air duct is connected with reversible emergency fan group, air-valve, silencer, air duct etc. that both ends tunnel ends are arranged.
(3) operation principle：Several groups are respectively set corresponding to uplink and downlink driving section tunnel on tunnel top civil engineering air duct
" one-tunnel two-tracks " tunnel is separated into several sections by electric assembling air-valve by electric assembling air-valve, ensures to only exist one in each section
Train of vehicles is run.When in running tunnel fire incident occurs for vehicle, it is arranged on civil engineering air duct at the top of unlatching fire section
Air-valve is combined, reversible emergency fan group excludes flue gas in the civil engineering air duct of tunnel top, combination air-valve by being arranged, can
Ensure the safety of remaining non-vehicle that catches fire while effectively excluding flue gas adjacent to train.
(4) there are problems：Tunnel top civil engineering air duct is set, and civil construction difficulty is big, civil engineering and equipment investment are high, such as area
Between tunnel both ends be arranged underground station, then on underground station form influence it is very big.
