Embodiment Construction
[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0042] In this embodiment, as shown in Figure 1, a kind of fire ventilation and smoke exhaust experimental simulation device based on the urban underground traffic connection tunnel system, the urban underground traffic connection tunnel is a two-way vehicle single carriageway; the experimental simulation device includes a simulated fire source device, a tunnel Longitudinal smoke control optimization device, fire detection device, multi-characteristic parameter measurement device and tunnel slope adjustment device.
[0043] Such as Figure 1a , Figure 1b As shown, the urban underground traffic connection tunnel experiment simulation device is composed of four single-hole tunnels, and the simulation device is placed in the direction of up north, down south, left west, right east. There are a total of 8 entrances and exits, namely, exit 1 on th...
