Embodiment Construction
[0037] see figure 1 , 2 , 3 (for the sake of simplicity, some structures irrelevant to the present invention are omitted in the figure). The underground tunnel in this specific embodiment includes six floors, and the underground tunnel includes: a first circular tunnel 1, a second circular tunnel 2, a first rectangular tunnel 3, a second rectangular tunnel (not shown in the figure), an equipment corridor Zone 5, the first lane slab 6, the second lane slab 7, and the longitudinal evacuation structure of the underground tunnel.
[0038] The second circular tunnel 2 is parallel to the first circular tunnel 1 , and there is a space between the second circular tunnel 2 and the first circular tunnel 1 . One end of the first rectangular tunnel 3 connects one end of the first circular tunnel 1 and one end of the second circular tunnel 2 , and the first rectangular tunnel 3 connects the first circular tunnel 1 and the second circular tunnel 2 . The other end of the first rectangular...

The invention relates to a longitudinal evacuation structure of a tunnel, in particular to a longitudinal evacuation structure of an underground tunnel. The longitudinal evacuation structure comprises a connection ramp and a turning lane which are arranged in an equipment pipe galley area of a rectangular tunnel, wherein one end of the connection ramp is connected with a layer on which two lane plates are positioned, the other end of the connection ramp is connected with a layer on which two rescuing and firefighting vehicle passages are positioned, the turning lane is arranged on the layer on which the two rescuing and firefighting vehicle passages are positioned, one end of the turning lane is connected with the connection ramp, and the other end of the turning lane is connected with one of the two rescuing and firefighting vehicle passages. The invention also relates to the underground tunnel with the longitudinal evacuation structure of the underground tunnel. According to the invention, the problem that in the existing evacuation structure of the underground tunnel has low firefighting and rescuing efficiency is solved.
Description
technical field [0001] The invention relates to a longitudinal evacuation structure of a tunnel, in particular to a longitudinal evacuation structure of an underground tunnel. The invention also relates to an underground tunnel with such a longitudinally evacuated structure of the underground tunnel. Background technique [0002] Fire is the key disaster type that the road tunnel disaster prevention system prevents. The evacuation and rescue of long tunnels is difficult, and once a fire occurs, it may cause large economic losses and social impact. Based on the principle of "people-oriented", one of the key technologies of road tunnel fire protection system is to ensure the safety and efficiency of personnel evacuation and fire rescue. [0003] There are three general modes of evacuation and rescue in tunnels: horizontal mode, combined mode of horizontal and vertical, and vertical mode. The horizontal mode refers to the evacuation or rescue from one tunnel to the other tun...
