Subway station fire hazard simulation experiment platform

Abstract

The invention relates to a subway station fire hazard simulation experiment platform, provides a subway station interior fire hazard simulation experiment platform and relates to subway fire hazard accident simulation equipment which is used to carry out experiment research on a generation and development mechanism of the subway station fire hazard accident, a control, prevention and treatment technology. The platform comprises a large-scale subway station entity model, a fire source system, a ventilation and smoke exhaust system, a fire hazard detection alarm system, a experiment measurement acquisition system and a data analysis system. The large-scale subway station entity model is made of a fireproof material and is a multi-layer building structure which comprises an interval tunnel, a platform, a station hall, an equipment room and the like. The whole entity model can be dismounted and combined. The fire source system can simulate different fire hazard scenes and generate approximately real hot smoke of the fire hazard. A problem of being difficult to develop a field experiment research on the urban mass transit subway fire hazard accident can be solved by the experiment system platform. Three-dimensional experiment simulation of subway fire hazard accident of different station structures, such as underground, deeply burying, an elevated type, an island style, a side type, a central nave and the like.

Description

technical field [0001] The invention relates to a device for experimental research on the spread and control of fire smoke in a subway station, in particular to a fire simulation experiment platform for a subway station. [0002] Background technique [0003] It is difficult to use a full-scale physical model to carry out experimental research on disaster accidents in a specific space. It is a necessary, scientific, economical and feasible method to use a certain scale simulation experimental model to carry out research. Most of the simulation experiment system platforms at home and abroad are designed and developed based on scale simulation technology and combined with specific needs. For example, in the study of fire accidents in buildings, Thomas et al. used a 1 / 10 reduced-scale model to study the smoke spread in large-space buildings, and Morgan used a 1 / 10-reduced model of shopping malls and atrium-style large spaces to study the atrium. Fire smoke control laws, W. ...

AI Technical Summary

Problems solved by technology

However, the applicable objects and applicable functions of the existing simulation experiment system platform are relatively single, which can only meet the specific needs of certain types of projects; or the scale of the model is too small, which will bring large similarity errors in the experimental research. Unable to meet the needs of in-depth research on disaster accident simulation experiments

[0004]At present, there is no subway station experimental model platform in China to simulate the experimental research of smoke spread and control in subway fires. Therefore, how to establish a multi-functional platform for subway fire accidents A large-scale experimental system platform to carry out experimental simulations of subway space fire spread, poisonous gas diffusion, etc., and experimental research on accident ventilation is an urgent problem in the field of urban rail transit.
