[0002] At present, with the rapid development of my country's railway construction industry, the number and length of railway tunnels in my country are increasing. While it brings great convenience to people's travel to a certain extent, it also brings many safety hazards such as fire hazards. In order to study the flow law and ventilation strategy of smoke in different types of tunnels when fire occurs, a tunnel structure model with the same shape and structure as the actual tunnel is designed for fire test, which can effectively guide the structural design of ventilation and smoke exhaust mode in the actual operation of the tunnel, thereby improving the safety of railway tunnel operation and the efficiency of solving fire accidents.

[0003] However, although conducting full-scale tunnel fire research is the most direct research method, due to the particularity of the tunnel structure and the huge aspect ratio, the full-scale tunnel test is not only large-scale, difficult to operate, and costly, but also difficult to obtain a large amount of accurate experimental data. Therefore, small-scale simulation test research is particularly important in the research methods for tunnel fires. The use of small-scale simulation test systems can effectively study and analyze the smoke flow laws and ventilation conditions in the simulated test tunnel, but the common small-scale tunnel fire test systems currently often have defects such as complex system structure, difficult splicing, time-consuming construction, large space occupation, weak thermal insulation and heat insulation performance, weak high-temperature insulation performance, and inconvenient monitoring and observation.

[0004] Therefore, it is an urgent problem to be solved by technical personnel in this field to provide a fire model test system for flat-guided rescue stations on both sides of a single-hole double-track tunnel, which has a simple structure, is easy to assemble, and can be used in the laboratory to study and analyze characteristic parameters such as smoke flow laws, temperature fields, thermal radiation values, and ventilation strategies in extra-long railway tunnels when a fire occurs.

The first smoke exhaust pipe 221 is a cylindrical smoke exhaust pipe with a T-shaped cross-section, and the bottom of the vertical section of the first smoke exhaust pipe 221 is fixed to the upper end of the smoke exhaust port 1222. The second smoke exhaust pipe 222 is a cylindrical smoke exhaust pipe. The second smoke exhaust pipe 222 is arranged along the parallel evacuation channel 12 and is connected to the transverse section of the first smoke exhaust pipe 221 or connected to other second smoke exhaust pipes 222.

[0075] This embodiment can effectively exhaust the smoke in the main tunnel channel 11, improve the compactness of the overall structure of the smoke exhaust device, and facilitate the measurement of the smoke flow pattern in the test system, so as to formulate a corresponding ventilation strategy.

[0076] like Fig.13As shown, in this embodiment, the monitoring device includes a smoke sensor, a camera, a temperature sensor and a control terminal. There are multiple smoke sensors, and the multiple smoke sensors, cameras, and temperature sensors are evenly arranged at the top of the main tunnel basic module 111, the main tunnel observation module 112, the main tunnel smoke exhaust port module 113, the main tunnel combustion module 114, the main tunnel connection module 115 and the transverse connection channel protection door module 131, and the multiple smoke sensors, cameras, and temperature sensors are communicatively connected to the control terminal, and the control terminal is communicatively connected to the smoke exhaust fan.

[0077] In this embodiment, the smoke sensor, the camera, and the temperature sensor are arranged at intervals of 1 m;

[0078] In other embodiments, the smoke sensor, the camera, and the temperature sensor are arranged at intervals of 0.5-2 m.

[0079] Specifically, one of the simulation embodiments is that when a fire occurs on one side of the main tunnel passage 11, the smoke sensor, camera, and temperature sensor monitoring equipment discover the fire point, and the smoke exhaust fan is started by the control terminal. The smoke exhaust fans located in the parallel evacuation passage 12 all supply air in the direction of the parallel evacuation passage 12, which can not only send the smoke and dust at the fire point into the smoke exhaust passage 22, but also prevent the smoke and dust on the fire side from going to the other main tunnel passage 11. The escaping personnel can escape through the parallel evacuation passage and the other main tunnel passage 11; and the smoke exhaust fan can adjust the air volume according to the data of the smoke sensor, camera, and temperature sensor obtained by the control terminal to ensure the timeliness of smoke removal.

[0080] This embodiment simulates the tunnel and the fire, and can accurately measure the smoke concentration, temperature and smoke flow conditions in the main tunnel basic module, the main tunnel observation module, the main tunnel smoke exhaust port module, the main tunnel combustion module, the main tunnel connection module and the transverse connecting channel protection door module at different positions when a fire occurs in the tunnel, so as to facilitate the study and analysis of characteristic parameters such as the smoke flow law, temperature field and thermal radiation value in the tunnel, help to simulate the fire in the newly built tunnel and then set the position of equipment such as smoke exhaust fans to ensure the effectiveness of fire rescue, and help to trace the fire in the already built tunnel and then adjust the layout position of the original smoke exhaust fans to ensure the effectiveness of fire rescue.
