The present invention relates to an apparatus for simulating fire extinguishing and ventilation of a railway tunnel (hereinafter referred to as a simulation apparatus), and more particularly, to a tunnel that is already being constructed or under construction using a model of a reduced railway vehicle and tunnel. In the simulated fire test, the center and one end of both sides of the shelf where the model tunnel, the model track, and the model railway vehicle are installed to implement the model tunnel and the model track gradient according to the slope of the terrain where the actual tunnel is constructed or the arbitrary inclination angle are implemented. By constructing the inclination control device, experiments were conducted on the flow trend of smoke, smoke control performance, and evacuation of passengers in a model tunnel in which a gradient was formed at the same angle as the actual tunnel and track by the inclination control device. It relates to a tilt control device (hereinafter, referred to as a tilt control device) of the railway tunnel fire-extinguishing experiment apparatus that can be analyzed through.

In general, due to the geographical characteristics of Korea where 70% of the country is a mountainous region, railway tunnels are constructed so that railroad cars can run smoothly in the highlands. There is no ventilation device in the domestic railway tunnel for discharging high-temperature smoke spread inside the tunnel in the event of a fire in the emergency situation. There was a big problem that the passengers in the railroad car and the evacuated passengers choked and lost their lives.

In addition, in foreign countries, a ventilator is installed inside the tunnel to discharge hot smoke, which is diffused into the tunnel, in the emergency situation due to a fire. Ventilation fan is installed in the duct installed in contact with the outside air in the ceiling of the tunnel without considering the gradient, and only the ventilation fan drive has a limitation in discharging smoke in the tunnel to the outside of the tunnel. Since the time and speed at which hot smoke spreads throughout the tunnel is very fast compared to the time and discharge flow rate to the outside of the tunnel, this also diffuses into the tunnel before the smoke in the tunnel is completely discharged to the outside of the tunnel. The smoke causes the passengers in the railcar and the evacuated passengers to choke and lose their lives. There was also a problem.

In the case of the conventional ventilation device as described above, since the size and performance of the ventilation device varies depending on the characteristics and conditions of the tunnel, it is very difficult to simply apply the conventional ventilation device to a domestic railway tunnel, and to install the ventilation device. In order to meet the domestic railway tunnel situation, there was also a cumbersome problem of having to redesign and install.

In addition, there is another object to verify the ventilation performance of the railway tunnel according to the actual fire conditions using the simulation apparatus to which the inclination control device of the present invention is applied.

Moreover, when the simulation fire test is performed using the simulation apparatus to which the inclination control device of the present invention is applied as described above, the simulation test is more accurate than the computer simulation method used to examine the pre-ventilation performance of the tunnel under construction. In addition, it is possible to verify the ventilation performance of the ventilation equipment of the tunnel more accurately in advance by comparing and comparing the simulated fire test results using the scaled down model with the computer simulation results. There is another purpose.
