Fire model test system for single-hole single-line tunnel single-side horizontal guide type rescue station

Abstract

The invention discloses a fire model test system for a single-hole single-line tunnel single-side horizontal guide type rescue station. The system comprises: a tunnel system, wherein the tunnel systemcomprises a main tunnel passage, a parallel evacuation passage and a transverse connecting passage, the main tunnel passage is a longitudinal passage, the parallel evacuation passage is parallelly arranged on one side of the main tunnel passage, and the transverse connecting passage is transversely arranged and perpendicularly communicated with the main tunnel passage and the evacuation passage;a fire source simulation device which is arranged in the main tunnel channel; a smoke discharge pipeline; and monitoring devices which are used for monitoring the flue gas concentration and the flue gas flow rule in the main tunnel passage, the parallel evacuation passage and the transverse connecting passage. The system can be assembled in a modular mode, is simple in structure, good in stability, easy to assemble, high in universality and convenient to test and operate, can accurately record and analyze characteristic parameters such as a smoke flow rule, a temperature field, a heat radiation value and a ventilation strategy when a fire occurs in a railway tunnel, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of fire safety, and more specifically relates to a fire model test system for a single-hole, single-track tunnel and one-side flat guide type rescue station. Background technique [0002] With the development of high-speed railways and passenger dedicated lines in China and the rise of the construction of the western railway network, the proportion of super-long railway tunnels in the line is getting higher and higher. As we all know, due to the structural characteristics of the super-long railway tunnel, once a fire breaks out in the tunnel, it is difficult for external rescuers to reach the scene in a short time to carry out rescue work, making it difficult for people to escape. [0003] In modern tunnel fire research, it is of great significance to ensure the efficient and safe operation of tunnels by using simulation tests to study the smoke flow laws and ventilation strategies under fire conditions in t...
