For example, the Chinese invention patent with the application number of 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 ; but for particularly long tunnels, especially those with many vehicles, the ventilation effect of this method is extremely poor

Embodiment Construction
[0015] As attached figure 1 , 2 The exhaust gas exhaust structure of a road tunnel shown includes a traffic tunnel 10, and a ventilation channel 20 arranged on the side of the traffic tunnel 10 and separated from the traffic tunnel 10 by a partition wall 101. The two ends of the ventilation channel 20 are closed to form The enclosed space communicates with the traffic tunnel 10 through the exhaust branch pipe 30 arranged on the partition wall 101. The exhaust branch pipe 30 includes an extension pipe 301 extending to the partition wall 101 on the wall inside the traffic tunnel 10, and the extension pipe 301 There are a number of air inlets aligned with the inner and lower parts of the traffic tunnel 10, the number of air inlets depends on the length of the tunnel, usually one per meter; at the outlet of the exhaust branch pipe 30, there is a ventilation device 40 on the ventilation channel 20 An exhaust main pipe 50 communicating with the outside is provided, and the exhaust...

The invention belongs to the field of municipal construction and relates to a tunnel, in particular to an exhaust gas discharging structure of a highway tunnel. The exhaust gas discharging structure comprises an open traffic tunnel. A ventilating channel which is separated from the open traffic tunnel through a partitioning wall is arranged on at least one side of the open traffic tunnel. The ventilating channel and the open traffic tunnel are communicated through a ventilating branch pipe arranged on the partitioning wall. An air pumping device communicated with the ventilating branch pipe is arranged in the ventilating channel. A ventilating header pipe communicated with the outside is arranged on the ventilating channel. The exhaust gas discharging structure is reasonable, vehicle exhaust in the tunnel can be discharged into the ventilating channel quickly and efficiently and then can be discharged out, and obvious effect is achieved especially on a long tunnel with a plurality of vehicles.
Description
Technical field [0001] The invention belongs to the field of municipal construction, and relates to a tunnel, in particular to an exhaust gas discharge structure of a highway tunnel. Background technique [0002] In highway tunnels, vehicles that travel will continuously emit harmful exhaust gas and smoke. As the tunnel concentrates a certain length of vehicle exhaust, it is necessary to set up a structure for ventilation and exhaust gas in the tunnel to ensure the fresh air in the tunnel and ensure that the tunnel is open to traffic. Safety. For example, the Chinese invention patent with the application number 200910050827.2 and the application date 2009-05-08 discloses a method for concentrated exhaust emission of a longitudinally ventilated road tunnel. The road tunnel includes an upward tunnel and a downward tunnel. A roundabout air duct is set at the entrance of the tunnel and the downward tunnel, so that the tunnel airflow flowing in the direction of the traffic flo...
