Abstract

The invention provides a liftable slope-variable tunnel fire simulation device and a method thereof. The device is mainly composed of four parts, namely, a tunnel main body, a longitudinal ventilationsystem, a combustion source and a supporting measurement and control system; the tunnel main body includes a tunnel frame, a supporting rack, fireproof cloth, tempered glass and a magnesium oxide board wall; the tunnel ventilation system includes a frequency-adjustable axial flow fan and a rectification net; the tunnel combustion source includes a combustion dish and a tripod; and the tunnel supporting measurement and control system includes an electronic balance, an anemometer, a laser transmitter, a thermocouple and a camera. The simulation device has the advantages of little experiment consumption, high repeatability, and capability of comprehensively detecting the changes of temperature and wind speed under different slopes and lifting conditions.

Description

technical field [0001] The invention relates to a simulation device, which is used for simulating tunnel fire and observing the change of temperature and the flow of smoke in the tunnel, in particular to an ascending and descending variable-slope tunnel fire simulation device and a method thereof. Background technique [0002] With the deepening of reform and opening up, frequent exchanges between cities have increased the demand for the construction of road tunnels, and large cities have also accelerated the construction of subways that are convenient for people to travel. However, with the increase of tunnel construction, tunnel safety accidents are gradually increasing. Due to the characteristics of long tunnel distance and poor ventilation conditions, it is easy to cause large-scale casualties and serious economic losses after a fire occurs. In order to facilitate the escape of personnel and reduce casualties, longitudinal ventilation is generally adopted in the tunnel ...
