Problems solved by technology

Due to its huge structure, the cost of conducting a full-scale tunnel fire test is high, the operation is difficult, and it is difficult to obtain a large amount of test data. Therefore, at present, small-scale simulation tests are mostly used, but usually small-scale simulation test systems can only simulate one or a few Several tunnel forms, poor versatility

Abstract

The invention discloses a double-hole single-line tunnel transverse channel smoke exhaust type rescue station fire model test system, which comprises a tunnel system, and is characterized in that thetunnel system comprises main tunnel channels and a transverse connecting channel, and the transverse connecting channel is transversely arranged between the two main tunnel channels and is verticallycommunicated with the two main tunnel channels; fire source simulation devices are arranged in the main tunnel channels; a smoke exhaust pipeline is arranged at the top of the transverse connecting channel; and monitoring devices are arranged in the main tunnel channels and the transverse connecting channel. According to the invention, a fire scene in a tunnel can be simulated, the flue gas concentration, the flue gas flow rule, the temperature field and the heat radiation value in the tunnel are observed, monitored and recorded, the accuracy and effectiveness of tunnel fire test research areimproved, modular splicing of the main tunnel channels can be achieved, all the modules with different functions can be repeatedly used according to the requirements of different positions, the manufacturing difficulty is lowered, and the splicing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel fire prevention, and more specifically relates to a fire model test system for a double-hole single-line tunnel cross-channel smoke exhaust 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 co...
