Single-hole double-track tunnel two-side horizontal guide type rescue station fire model test system

Abstract

The invention discloses a single-hole double-track tunnel two-side horizontal guide type rescue station fire model test system. The system comprises a tunnel system, a fire source simulation device, asmoke exhaust device and a monitoring device. The tunnel system comprises a main tunnel passage, parallel evacuation passages and transverse connecting passages, the two parallel evacuation passagesare arranged on the two sides of the main tunnel passage in parallel, and the transverse connecting passages are perpendicular to and communicate with the main tunnel passage and the parallel evacuation passages. The fire source simulation device is arranged in the tunnel system; the smoke exhaust device comprises a smoke prevention fan, a smoke exhaust pipeline and a smoke exhaust fan, the smokeprevention fan is arranged in the transverse connecting passages, the smoke exhaust pipeline is communicated with the main tunnel passage, and the smoke exhaust fan is arranged at the tail end of thesmoke exhaust pipeline and exhausts smoke to the outside of the tunnel; the monitoring device is arranged in the tunnel system and used for monitoring the smoke concentration and the smoke flowing rule in the main tunnel passage, the parallel evacuation passages and the transverse connecting passages. Modularized assembling is adopted, assembling is easy and convenient, and the real tunnel fire situation can be fully simulated.

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 rescue station with flat guides on both sides of a single-hole double-track tunnel. Background technique [0002] At present, with the rapid development of my country's railway construction industry, the number and length of railway tunnels in my country continue to increase, which brings great convenience to people's travel to a certain extent, but also brings many safety hazards such as fire hazards Wait. In order to study the smoke flow law and ventilation strategy in the case of fire in different types of tunnels, a tunnel structure model with the same shape and structure as the actual tunnel is designed for fire tests, which can be effectively used to guide the actual operation of the tunnel. For the structural design of the ventilation and smoke exhaust mode, the safety of railway tunnel operation and the efficiency of solv...

Problems solved by technology

[0005] In view of this, in order to solve the technical problems of the existing technical problems such as the complex structure of the small and medium-sized tunnel fire simulation test system and the inconvenient detection and observation of test data, the invention provides a simple structure, easy to assemble, and can be carried out in the laboratory. In the case of a fire, the fire model test system for the fire model test system of the flat-guided rescue station on both sides of the single-hole double-track tunnel for the research and analysis of the characteristic parameters such as the smoke flow law, temperature field, heat radiation value and ventilation strategy in the tunnel
