[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Embodiment 1:

[0025] Reference Figure 1 and Figure 4, the shelter facilities of the emergency rescue station at the entrance of the plateau railway tunnel under the influence of multiple disasters include the main tunnel 1, and also include: escape passage 3. Here, for the tunnel entrance evacuation type tunnel entrance emergency rescue station, the location of the escape passage 3 can be set on the ground outside the tunnel. The area in the escape passage 3 is usually not less than 0.5㎡ / person. 0.5㎡ / person can ensure that people can stand and have a certain amount of space for activities. For remote areas, the time required for rescue forces to reach the rescue site will increase. Therefore, the waiting time of personnel in the escape passage 3 is longer and they cannot stand for a long time. In order to allow personnel to have a certain space to sit down and rest in the escape passage 3, we will increase the area of ​​the escape passage 3 of the plateau railway tunnel group to not less than 0.5㎡ / person. It should be designed to be less than 0.7 m2 / person, wherein the escape passage 3 is connected to the main tunnel 1 through the evacuation passage 2. A ventilation system should be installed in the evacuation passage 2 to ensure that personnel are evacuated facing the fresh air. An oxygen supply unit 301 and a heating unit 302 are installed in the escape passage 3. The oxygen supply unit 301 adopts the existing technology, preferably the Womute brand, model: BNG-10L / MIN, with electricity as the power and air as the raw material, and adopts pressure swing adsorption (PSA) technology, that is, the lithium molecular sieve has the characteristics of increasing the adsorption capacity of nitrogen under pressurized state and reducing the adsorption capacity of nitrogen under reduced pressure, forming a cyclic process of pressurized adsorption and reduced pressure desorption, realizing the separation of oxygen and nitrogen in the air, and continuously preparing oxygen for diffusion. The entire oxygen production process is a pure physical adsorption process without chemical reactions. The heating unit 302 adopts a heating lamp in the prior art, and a ventilation duct 303 is fixedly arranged at the top of the escape channel 3, which is conducive to the air circulation in the escape channel 3 and reduces the accumulation of toxic and harmful gases; and a parking area 101 is fixedly arranged on the main tunnel 1 for the parking of the burning train. For the tunnel evacuation type, the parking area 101 is located in the main tunnel and open line segment area of ​​the emergency rescue station, and the open line segment length is less than the critical open line segment length for setting mechanical ventilation. A ventilation and smoke exhaust system should be set to ensure that the fire smoke does not invade the adjacent tunnels.

[0026] When in use, by fixing the oxygen supply unit 301 and the heating unit 302 in the escape passage 3, the living environment in the escape passage 3 can be improved for the plateau areas with the characteristics of low temperature and low oxygen, the occurrence of secondary disasters can be reduced, the safety and comfort of the refuge can be ensured, the survival ability of the victims can be increased, and the time for rescue can be increased.

[0027] Reference Figure 4A gas detection unit 305 and a thermometer 306 are fixedly installed in the avoidance channel 3, and a lighting lamp 304 is fixedly installed on the top of the avoidance channel 3. When in use, the gas detection unit 305 can be used to detect the gas in the avoidance channel 3, such as the oxygen content, and the thermometer 306 can detect the temperature in the avoidance channel 3, so as to adjust the heating temperature or irradiation time of the heating unit 302 according to the actual situation. The lighting lamp 304 can provide lighting to improve the use effect.

[0028] Reference Figure 4 A protective door is fixedly installed at the entrance of the escape channel 3. The protective door is preferably a fire-proof fully enclosed type, which can prevent the flame from spreading to the escape channel 3 and reduce the entry of toxic gases into the escape channel 3. An observation window is fixedly installed on the protective door. By fixing the protective door in the escape channel 3, the protection effect of the internal space of the escape channel 3 can be improved, and the safety of personnel in the escape channel 3 can be ensured.

[0029] Embodiment 2:

[0030] Reference Figure 2 , which is basically consistent with the content of Example 1. On the basis of Example 1, we subdivide the position of the escape passage 3. For the cave entrance auxiliary tunnel type cave entrance emergency rescue station, the position of the escape passage 3 is selected as the auxiliary tunnel, which does not require additional civil engineering design and construction, thereby improving the use effect.

[0031] Embodiment three:

[0032] Reference Figure 3 , which is basically consistent with the content of Example 1. On the basis of Example 1, we further expand the position of the escape channel 3. For the cave entrance emergency rescue station with encrypted cross-channel at the cave entrance, the position of the escape channel 3 is selected as the flat guide channel. There is no need to increase the design and construction of civil engineering, which increases the selectivity of the position of the escape channel 3.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
