For example, the Chinese invention patent with the application number 200910050827.2 and the application date of 2009-05-08 discloses a method for centralized exhaust gas discharge in a longitudinally ventilated road tunnel. The road tunnel includes an uplink tunnel and a downlink tunnel. A roundabout air duct is set at the entrance of the tunnel and the downlink tunnel, so that the tunnel airflow flowing in the direction of traffic flows back to the opposite tunnel through the roundabout air duct, and at least one centralized exhaust shaft is respectively set inside the uplink tunnel and the downlink tunnel However, in some special cases, such as car accidents, vehicle spontaneous combustion, etc., a large amount of smoke will be generated, this method cannot meet the smoke emission requirements, and for particularly long tunnels, especially tunnels with many vehicles, this method has a very good ventilation effect Poor, personnel cannot be evacuated in time, which is likely to cause serious consequences

Abstract

The invention relates to a safety traffic tunnel facilitating smoke discharging. The safety traffic tunnel comprises a traffic tunnel body. One side of the traffic tunnel body is provided with a smoke discharging channel. The smoke discharging channel is separated from the traffic tunnel body through a first partition wall, and the two ends of the smoke discharging channel are closed. The inner side, away from the traffic tunnel body, of the smoke discharging channel is provided with a safety channel separated from the smoke discharging channel through a second partition wall. An escape channel which is isolated from the smoke discharging channel and communicates the safety channel with the traffic tunnel body is arranged between the safety channel and the traffic tunnel body. The smoke discharging channel is communicated with the traffic tunnel body through a smoke discharging branch pipe transversely penetrating through the first wall body. The smoke discharging channel is communicated with the external world through a main smoke discharging pipe. Due to the arrangement of the smoke discharging channel, smoke inside the traffic tunnel body is rapidly sucked to a large scale and then discharged to the external world, and the smoke discharging effect is remarkable. On the emergency condition, people can pass through the escape channel to enter the safety channel, and life safety of people is ensured.

Description

technical field [0001] The invention relates to a tunnel, in particular to a safe traffic tunnel which is easy to exhaust smoke, and belongs to the field of road construction. Background technique [0002] In the road tunnel, the vehicles driving will continuously emit harmful exhaust gas and smoke. Since the tunnel concentrates a certain length of automobile exhaust, it is necessary to set up a ventilation and exhaust gas structure in the tunnel to ensure the fresh air in the tunnel and ensure the opening of the tunnel. Safety. For example, the Chinese invention patent with the application number 200910050827.2 and the application date of 2009-05-08 discloses a method for centralized exhaust gas discharge in a longitudinally ventilated road tunnel. The road tunnel includes an uplink tunnel and a downlink tunnel. A roundabout air duct is set at the entrance of the tunnel and the downlink tunnel, so that the tunnel airflow flowing in the direction of traffic flows back to th...
