Description

Technical Field

[0001] The utility model relates to the technical field of underground tunnels, and specifically relates to a longitudinal evacuation structure for an underground tunnel. Background Technique

[0002] The key disaster prevention targets of the road tunnel disaster prevention system are, when a disaster occurs, to evacuate through the underground tunnel to avoid people being affected by natural disasters. Among them, the "longitudinal evacuation structure for an underground tunnel" disclosed in the patent number "CN217176695U" has solved various drawbacks in the current market, such as in a long tunnel when a disaster occurs, there is a lack of a convenient shelter space in the underground tunnel, it is not convenient for people to take emergency refuge, and people cannot hold on until the arrival of the rescue team. After further retrieval, it is found that the "longitudinal evacuation structure for an underground tunnel and an underground tunnel" disclosed in the patent number "CN102383807B" has effectively solved technical drawbacks such as the reduction of the fire fighting and rescue efficiency after the increase of the spacing of the pedestrian cross-passages, the lack of effective evacuation and rescue of firefighters in the longitudinal evacuation passage, and the disorderly evacuation of the drivers and passengers, which is extremely likely to lead to casualties. However, in actual use, a longitudinal evacuation structure for an underground tunnel with a similar structure still has many defects. For example, most of the existing underground evacuation passages lack a ventilation mechanism, resulting in the occurrence of oxygen deficiency when there are too many people during the underground evacuation for preventing natural disasters. And a small number of ventilation mechanisms lack a protection mechanism, resulting in the situation that external sundries are easily fallen into the ventilation pipe and cause blockage. Therefore, it is necessary to design a longitudinal evacuation structure for an underground tunnel. Content of the Utility Model
