Embodiment Construction

[0031] figure 1 It is a schematic diagram of the system of the present invention; the large-section immersed tube tunnel fire simulation system of this embodiment includes an experimental oil pan 2 and an oil supply device, and the oil supply device includes an oil pool and a supply for transporting fuel in the oil pool to the experimental oil pan. Oil pump 13; use the oil supply pump 13 and the experimental oil pan 2 to provide fuel to simulate a fire caused by a vehicle accident. At the same time, the simulated fire system is standardized, which is convenient for use and removal, and the fuel supply can be adjusted to simulate fires of different intensities .

[0032] In this embodiment, the simulated fire system also includes a control device, and the control device includes:

[0033] The oil level detection unit 3 is arranged on the experimental oil pan 2 to detect the fuel oil level in the experimental oil pan 2; through the detection of the oil level, the amount of fuel...

Abstract

The invention discloses a fire simulation system for a large-crosssection immersed tube tunnel. The fire simulation system comprises an experimental oil tray and an oil supplying device, wherein the oil supplying device comprises an oil pool and an oil supplying pump which is used for conveying fuel oil in the oil pool to the experimental oil tray. According to the fire simulation system, a real fire scene is simulated and monitored by adopting a simulated tunnel structure, and a real fire scene of the tunnel is simulated under laboratory conditions, so that the acquisition of real fire data of the tunnel under various conditions is facilitated, disaster avoidance or timely emergency treatment with pertinence is facilitated, and an important theoretical basis is provided for the construction and fire control of the tunnel.

Description

technical field [0001] The invention relates to an experiment system for tunnel safety, in particular to a comprehensive experiment system for tunnel fire. Background technique [0002] As a tubular structure, highway tunnels have a narrow space and low visibility. Coupled with the black hole, black frame effect and the effect of the inner wall of the tunnel when entering the tunnel, vehicle collisions and vehicle anchorage accidents are very likely to occur in the tunnel. , and easily induce various fires. Therefore, due to the above-mentioned particularity of the spatial structure of highway tunnels, the potential for fires in highway tunnels is universal. [0003] Once a fire breaks out in a highway tunnel, especially a long and extra-long highway tunnel, if it cannot be detected and extinguished in time, the fire will spread rapidly along the longitudinal direction of the tunnel and affect adjacent vehicles that are too late to evacuate; the heat wave generated by the c...
