In-subway evacuation structure

Abstract

The invention provides an in-subway evacuation structure. A tunnel and subway stations are arranged in a subway; each subway station is provided with a platform plate; the position between every two adjacent subway stations is a subway interval; the in-subway evacuation structure comprises an interval evacuation structure; the interval evacuation structure comprises interval evacuation platforms;the interval evacuation platforms extend in the length direction of the subway tunnel and is connected with the side wall of the subway tunnel; and the interval evacuation platforms extend to be connected with the platform plate. The problem that the interval evacuation platforms and the platform plate are discontinuous is solved through connection of the interval evacuation platforms and the platform plate, and even if a subway interval partition door is arranged at the end of a station, the interval evacuation platforms can still communicate with the platform plate. Meanwhile, people in theinterval can be prevented from going upstairs and downstairs twice for evacuation, the risk of in the process of the people going upstairs and downstairs is reduced, and the evacuation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of subway facilities, in particular to an evacuation structure in a subway. Background technique [0002] In recent years, due to the characteristics of high passenger capacity, punctuality, safety and convenience, the urban subway has gradually developed into the preferred method to solve the increasingly tense urban traffic problems. With the continuous densification of the subway network in major cities, the number of faults and fires in interval trains has gradually increased, which puts forward higher requirements for interval evacuation under emergency and fire conditions. How to quickly evacuate people in the interval and effectively avoid major safety liability accidents is an urgent problem to be solved. [0003] At present, the interval evacuation platform is generally disconnected 10m outside the end wall of the station. The end of the interval evacuation platform is provided with interval lower ...

AI Technical Summary

Problems solved by technology

Metro stations generally have the function of civil air defense emergency protection, and one end of the station will set up an interval civil air defense partition door. In extreme cases, when the train catches fire and the train loses power just at the civil defense door, the width of the general city subway partition door civil defense door is 3.8 m (the width of type A subway car is 3.0m, and the width of type B car is 2.88m). 0.46m, none of which meet the minimum evacuation width requirement of 0.55m in the "Code for Metro Design" GB50157-2013

In order to solve the problem that the width of the civil air defense door is not enough, some cities widen the civil air defense door to 4.2m. At this time, although the evacuation width of the train stopping at the civil air defense door is satisfied, passengers still need to go down the stairs from the section evacuation platform to the ballast bed. Across the civil air defense threshold and track drainage ditch, it is not convenient for passengers to evacuate
