Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0020] This application relates to a rescue facility for urban highway tunnels, including an escape passage 1, a warning unit, an escape unit 10, and a lifting unit 20.

[0021] The specific implementation method is as follows; please refer to it for details. Figures 1-2 and Figure 12 As shown, escape route 1 is located in a highway tunnel; the indicator unit includes a water level monitor 51, an alarm 52, and an evacuation indicator light 53; the water level monitor 51 is installed at the bottom of the inner wall of the highway tunnel; the alarm 52 is installed at the top and entrance of the highway tunnel; the evacuation indicator light 53 is installed on the wall of the highway tunnel; the escape unit 10 includes an escape staircase 11, a rescue platform 13, and a rest platform 12; the escape staircase 11 is erected in escape route 1, and the rescue platform 13 is connected to the escape staircase 11; the rest platform 12 is located between the rescue platform 13 and the escape staircase 11, and the rest platform 12 is connected to the top of the escape staircase 11. The lifting unit 20 includes a lifting channel 21, a track 23, a lifting mechanism, and a safety seat 22. The lifting channel 21 is located on one side of the escape passage 1 and extends from the bottom of the highway tunnel to the rest platform 12. The track 23 is installed in the lifting channel 21. The lifting mechanism is located in the rest platform 12. The safety seat 22 is located at the output end of the lifting mechanism and is movably connected to the track 23. Under the action of the lifting mechanism, the safety seat 22 moves from the bottom of the escape passage 1 to the rest platform 12. Escape passage 1, warning unit, escape unit 10 and lifting unit 20 constitute a set of rescue facilities; one or more sets of rescue facilities are set in the highway tunnel; each set of rescue facilities is set at a interval of 500m.

[0022] In the above embodiment, when a large amount of water accumulates in the highway tunnel, the water level monitor 51 automatically activates. When the water level reaches 0.5m, the alarm 52 lights up red and emits an emergency alarm sound. Simultaneously, the alarm light 52 at the tunnel entrance illuminates, alerting vehicles outside that there is a disaster inside the tunnel and entry is prohibited. The alarm light 52 inside the tunnel prompts trapped personnel to immediately evacuate through the nearest escape route. Simultaneously, the disaster signal is transmitted to the nearest fire and rescue department so that rescue personnel can quickly reach the scene. During a rapid escape, one can enter the rest platform 12 via the escape stairs 11 and escape from the rest platform 12 to the rescue platform 13 to await rescue. Handrails and lifebuoys are installed on the tunnel walls to assist various personnel in moving through the water. An escape route 1 is set up every 500m in the tunnel, and each escape route 1 has a lifting unit 20 on one side. When necessary, elderly people, children, and others with mobility difficulties can be directly transported to the rescue platform using the lifting unit 20.

[0023] In the above embodiment, most personnel use escape staircases, which rise from the top of the tunnel. A rescue platform is set up at a higher elevation after the staircases emerge from the ground. Trapped personnel wait for rescue on the rescue platform after escaping the tunnel. The escape staircases begin 0.5m above the bottom of the tunnel and extend to a spiral staircase at the top of the tunnel. Personnel ascend the spiral staircase and first reach a rest platform at an elevation of -2.5m (the outdoor ground level is ±0). Rest seats are provided on this platform, with rescue supplies placed underneath. Emergency call devices and CPR equipment are installed on the walls, allowing personnel to rest briefly and receive emergency treatment. Enclosed stairwells and stairs continue upwards from the rest platform. Fixed windows on the exterior walls of each floor of the stairwells allow for natural lighting. A waterproof, airtight door connects the stairwells to the rescue platform to prevent water from overflowing into the stairwells during floods. Trapped personnel can then continue up the stairwells to the outdoor rescue platform after reaching the rest platform.

[0024] When large-scale flooding occurs in the tunnel, water level monitors are installed to monitor the depth of the water, effectively alerting personnel and vehicles to assess the water depth and choose the optimal escape route. Alarms are also activated to transmit disaster signals to vehicles about to enter the tunnel, effectively reducing the scale of the disaster and casualties. Simultaneously, rescue signals are transmitted to the nearest fire and rescue department via communication units, effectively shortening rescue time and ensuring that trapped personnel receive the fastest possible rescue. Escape staircases are also installed to allow trapped personnel to quickly escape the disaster site, preventing them from being submerged or swept away by floodwaters. This not only improves evacuation efficiency but also helps individuals with lower mobility to evacuate quickly.

[0033] As one embodiment of this application, please refer to the specific details. Figures 9-11As shown, a sump 40 is provided on the ground of the highway tunnel, and a flood lift pump 41 is installed in the sump 40. The output end of the flood lift pump 41 is connected to a pipe 42. The pipe 42 is installed in the lifting channel 21, and an impeller 43 is installed below the output end of the pipe 42. A rotating shaft 44 is connected to the impeller 43. The end of the rotating shaft 44 away from the impeller 43 is connected to a duct 45.

The exhaust fan 46 delivers fresh air from the air duct 45 to the ceiling of the rest platform 12. A single-layer louvered air outlet 47 is set at the lower part of the air duct 45 to realize mechanical ventilation of the rest platform 12. When the non-powered vent cap 18 or the mechanical exhaust fan is working to exhaust air outward, due to the pressure difference between indoor and outdoor, air will automatically enter at the air supply louvers to circulate indoor air and ensure normal indoor air quality.

[0034] As one embodiment of this application, it is a single-layer rainstorm relief platform; please refer to the following for details. Figure 7 As shown, the rescue platform 13 is a single-layer structure set on the escape unit 10 and is open-air; the rescue platform 13 has an elevation of 1.5m and is surrounded by guardrails 130; this solution is suitable for most cities, such as some northern cities or cities with generally low rainfall. The platform elevation is 1.5m (outdoor ground level is ±0), it is an open platform, and guardrails are set on all sides. When the water level on the city road is less than 1.5m, trapped personnel can wait for rescue here or directly evacuate to the outdoor ground from this platform.

[0035] As one embodiment of this application, it is a two-layer rainstorm rescue platform; please refer to the following for details.
