The utility model provides a key system of discharging fume of highway tunnel segmentation, the system includes: at the 1st driving main cave's top, along vertically setting up a plurality of furred ceiling wind channel according to certain interval, the service tunnel top sets up main discharge flue, and every furred ceiling wind channel is a corresponding horizontal contact flue, one end and furred ceiling wind channel intercommunication, the other end and main discharge flue intercommunication of setting up all. The advantage does: because the utility model discloses set up a plurality of independent furred ceiling wind channels at the main cave top, furred ceiling wind channel bearing capacity is stronger, and the electronic exhaust port area that the bottom set up can expand 50m2 to,and the longitudinal separation can reach 1000m, has reduced electronic exhaust port quantity, has simplified the control prediction scheme of discharging fume. Left and right line tunnel is served tomain discharge flue, redu
