Abstract

The invention disclose a utility tunnel fire experiment platform system and an experiment method. A linear fire source experiment frame with freely-adjustable positions and a high-power fire source calorimeter system suitable for pipe gallery fire are arranged in a utility tunnel fire simulation laboratory; the flame height measuring and smoke layer thickness measuring device is arranged outside the utility tunnel fire simulation laboratory, and is used for preforming high-definition video recording on a utility tunnel combustion chamber area, and processing the recorded video to obtain a curve of flame height and smoke layer thickness changing with time; and the linear fire source experimental frame with freely-adjustable positions is arranged in the utility tunnel fire simulation laboratory, and thus the accurate movement and positioning in the horizontal direction and the vertical direction can be realized. The system and the method can realize simulation experiments of internal fires in utility tunnel under multiple spatial positions, measure data such as mass loss rate of fire source, heat release rate, flame height of fire source, thickness of smoke layer in pipe gallery andthe like in real time, and lay a foundation for scientific research of fires in the utility tunnel.

Description

technical field [0001] The invention relates to a simulated fire experiment system, in particular to a comprehensive pipe gallery fire experiment platform system and an experiment method, belonging to the technical field of fire safety. Background technique [0002] The urban comprehensive pipe gallery, also known as the common ditch, is a modern and intensive urban infrastructure that is built in the underground tunnel space and integrates a variety of municipal pipelines. This comprehensive pipe gallery includes electricity, telecommunications, water supply and drainage, gas, etc. All kinds of professional pipelines, especially cable and natural gas pipeline warehouses are prone to fire, gas leakage and other accidents, so there are great fire safety hazards. [0003] At present, there are few domestic researches on the law of fire in integrated utility corridors and relevant research on prevention and control technologies. Compared with other underground spaces, the cross...
