Multifunctional railway tunnel fire experiment platform

Abstract

The invention discloses a multifunctional railway tunnel fire experiment platform. Arc-shaped glass top plates and front and back vertical observation windows of a model are all made of transparent fire-resistant glass, so that air flow movement is conveniently observed, and a tunnel main body structure frame and a bottom plate are made of stainless steel. All segments of a main tunnel are in flanged connection with one another and are sealed by a transparent fireproof adhesive. A top partition plate with smoke exhaust ports and the arc-shaped tempered glass top plates are detachable, the different tunnel top plates can be selected and the relevant size can be adjusted according to the experiment needs, the arc-shaped tempered glass top plates are used for a longitudinal ventilation and smoke exhaust experiment of the tunnel, the top partition plate with the smoke exhaust ports is used for a concentrated smoke exhaust tunnel experiment, and vertical shafts can be installed over the smoke exhaust ports for a vertical shaft chimney effect experiment. A tunnel support base is of a steel structure, electric gradient adjusting can be conducted on the platform, and the gradient adjusting angle ranges from 0 degrees to 10 degrees. The main tunnel concentrated smoke exhaust experiment, the main tunnel longitudinal ventilation and smoke exhaust experiment and the vertical shaft chimney effect experiment can be simulated through the platform, and then a reasonable ventilation and smoke exhaust control scheme can be obtained.

Description

technical field [0001] The invention relates to the technical field of railway tunnel fire safety, in particular to a multifunctional railway tunnel fire experiment platform. Background technique [0002] With the development of railway tunnel engineering, the scale and number of long tunnels are also increasing. In order to ensure the safe operation of tunnels, it is necessary to guide the ventilation and smoke exhaust design through simulation experiments. However, it is difficult to establish full-scale and large-scale experimental platforms, and the practical operability is not strong, so small-scale experimental platforms are widely used. However, the current small-scale experimental platform has a single function and can usually only simulate one type of experiment. Therefore, it is urgent to establish a multi-functional experimental platform that can simulate multiple types of experiments.
