Abstract

The invention relates to the technical field of fire tests, and particularly relates to a fire test device and method for a subway turn-back track. The fire test device comprises an uplink tunnel, a downlink tunnel and a turn-back tunnel, and is characterized in that two ends of the turn-back tunnel are respectively connected with the uplink tunnel and the downlink tunnel, both the uplink tunnel and the downlink tunnel are provided with a tunnel fan, and the top part of the inner wall of the turn-back tunnel is provided with multiple groups of jet fans. In allusion to the condition that a train on fire stops in the turn-back tunnel or the uplink tunnel and the downlink tunnel which are adjacent to the turn-back tunnel, the fire test device can guide smoke to flow in a limited area and be discharged timely through controlling the uplink tunnel fan, the downlink tunnel fan and the jet fans, thereby creating a safe path for personnel evacuation in an emergency circumstance.

Description

technical field

[0001] The invention relates to the technical field of fire tests, in particular to a fire test device and method for subway switchback lines. Background technique

[0002] As a narrow and long underground confined space, the fire safety of tunnels has always been a hot issue concerned by relevant scholars at home and abroad. At present, the research on single-hole tunnel fire has established the prediction model of the maximum temperature above the fire source, the temperature vertical and horizontal attenuation model, the longitudinal distribution model of toxic gas, the optimization model of shaft smoke exhaust efficiency, and the critical wind speed prediction model. Most of these prediction models Based on the fitting analysis of small-scale experimental data, some models are adopted in the smoke control design of subways and highway tunnels and the compilation of standards and specifications.

[0003] The prior art models are all based on the dimension...
