Evacuation exit with man and car pass function in tunnel

Abstract

The invention discloses an evacuation exit with a man and car pass function in a tunnel. The evacuation exit comprises a car pass transverse passageway in the tunnel and evacuation ear holes formed inthe positions of the side walls of the ends of the car pass transverse passageway. Certain gaps are formed between the evacuation ear holes and the walls of main holes of the tunnel. The evacuation ear holes are perpendicular to the direction of the car pass transverse passageway. According to the evacuation exit with the man and car pass function in the tunnel, the car pass transverse passagewayand a man pass transverse passageway are integrated, the evacuation exit has the escape and rescue functions of the car pass transverse passageway and the man passage transverse passageway, the evacuation escape distance of people in danger is shortened, the influences of faults of fireproof rolling shutter doors on evacuation escape are avoided, the escape and rescue efficiency of people is improved, precious time for escape and rescue is gained to the maximum degree, the confidence in the safety performance of the tunnel can be improved, and bad social influences can be reduced; and construction is easy and convenient, the manufacturing cost is low, the structure is safe and reliable, and the evacuation exit is easily and rapidly recognized during escape.

Description

technical field [0001] The invention relates to the field of highway tunnel construction, in particular to an evacuation passage in a tunnel with the function of passing people and vehicles. Background technique [0002] According to the current "Code for Design of Highway Tunnels", emergency parking belts, cross passages for vehicles and cross passages for pedestrians need to be set up at a certain distance in long and extra long road tunnels to facilitate disaster prevention, rescue and operation and maintenance. Dangerous situations in long and extra-long highway tunnels not only seriously threaten human life and property safety, but also cause huge damage to transportation facilities and human production activities, reduce users' trust in tunnel safety performance, and cause adverse social impacts. Especially when a fire occurs in a tunnel, it has the characteristics of fast fire spread, fast smoke spread, easy to induce secondary traffic accidents, tight escape time, an...

Problems solved by technology

However, the disadvantage of the above structure is that although the width of the cross passage for vehicles is about 2m wider than that of the cross passage for pedestrians, its longitudinal separation distance is nearly three times that of the cross passage for pedestrians. The vehicle cross passage is relatively close but its fire shutter door is closed, which requires the persons involved in danger to walk to the pedestrian cross opening about 250m away before entering the side tunnel. In view of the rapid spread of the fire, especially the smoke Very fast, the existing cross-passages for vehicles and cross-passages for pedestrians are set along the tunnel, which will greatly delay the precious escape time of those involved in danger, and there are strong potential safety hazards; and the separate settings for cross-passages for vehicles and pedestrians will increase Increased construction difficulty and construction cost
