Fire disaster test device and method used for multi-line transfer stations of subway

Abstract

The invention provides a fire disaster test device and method used for multi-line transfer stations of a subway. The device comprises a multi-line transfer subway station model, a smoke exhaust prevention system and a fire disaster test system, wherein the multi-line transfer subway station model comprises a station A, a station B, a station C and a station D and is used for realizing multi-line transfer by adjusting stairs between stations and opening or closing of transfer channels; the smoke exhaust prevention system comprises a smoke exhaust pipeline arranged in each space of the multi-line transfer subway station model as well as a smoke exhaust fan connected with the smoke exhaust pipeline; the fire disaster test system is used for detecting smoke parameters under the condition of a fire disaster and performing monitoring processing. According to the rule that smoke diffuses through multiple transfer channels and stairs to multiple stations and the smoke exhaust ventilation network air distribution and smoke control scheme of multiple smoke prevention areas, diffusion of fire disaster can be effectively controlled, death of people is reduced, and financial loss is reduced.

Description

technical field [0001] The invention relates to the technical field of fire tests, and more particularly, to a fire test device and method for subway multi-line transfer stations. Background technique [0002] At present, there are three-line interchange stations and four-line interchange stations under construction or put into operation in the subway network of Beijing, Guangzhou and other cities, but most of the research on fire smoke control in subway stations focuses on single-line stations, and two-line interchange stations. The research on the bus station also only adopts the method of numerical calculation, and the existing research object does not involve the third-line or fourth-line transfer station. [0003] For single-track stations, the existing research mainly adopts model experiments, full-scale experiments and numerical calculations to establish the maximum temperature model of the roof, the longitudinal temperature distribution model of the roof jet, and the...

AI Technical Summary

Problems solved by technology

[0004] The structural forms of multi-line transfer stations are more complicated, and the diversification transfer methods of channel transfer and stair transfer are generally adopted. Existing research lacks the diffusion model of fire smoke through multiple transfer channels and stairs to multiple stations

[0005] The structural form of a multi-line transfer station determines the number and structure of its ventilation network to be more complex. Existing research lacks smoke exhaust systems for multi-line transfer stations in station halls, platforms, transfer channels, and ventilation systems. Ventilation network air volume distribution data and fire smoke control scheme under the joint action of station tunnel rail exhaust system
