Abstract

The invention provides a fire disaster simulating experiment platform for an underground traffic switching channel. The platform comprises a model main body simulating the underground traffic switching channel, a combustor butted to the model main body and generating smoke, and a smoke imaging system, wherein the smoke imaging system comprises laser sheet light sources and image recording devicesrecording smoke distribution images; the plurality of laser sheet light sources are distributed in the model main body, and planar laser emitted by the laser sheet light sources is parallel to the flowing direction of smoke; the plurality of image recording devices are in one-to-one correspondence with the laser sheet light sources and are distributed outside an observation window of the model main body; and each laser sheet light source and each image recording device in pair which correspond to each other are provided with light filters filtering out laser with the same wavelength. The firedisaster simulating experiment platform for the underground traffic switching channel can conveniently research the horizontal spreading feature of the smoke, and is particularly suitable for simulating the fire disaster of the underground traffic switching channel.

Description

technical field [0001] The invention relates to the technical field of fire experiments, in particular to a device for performing simulation experiments on the fire smoke diffusion characteristics of underground traffic conversion passages. Background technique [0002] With the acceleration of urbanization in our country, the population is oversaturated, and the traffic pressure is increasing. Traffic congestion has become a prominent problem faced by many cities. The development and utilization of underground space is an important measure to relieve traffic pressure and save land resources. As an important hub connecting the urban three-dimensional traffic network, underground traffic conversion channels are gradually being popularized and applied. Due to the closed nature of the underground space structure, when a fire occurs, the smoke exhaust and heat dissipation conditions are poor, the temperature is high, and the toxic smoke will accumulate rapidly, which will seriou...
