Description

Technical Field

[0001] The present invention relates to the field of traffic safety, and in particular to a railway rescue station provided with a service tunnel and a personnel evacuation and smoke control method, which is particularly suitable for ultra-long submarine railway tunnels. Background Art

[0002] With the advancement of railway construction technology and the increasing demand for faster travel, the construction of multiple cross-sea railway tunnels has become increasingly important. Tunnels are semi-enclosed spaces. If a fire occurs on a train, smoke quickly accumulates and the air temperature rises rapidly, posing a significant threat to passenger safety and property. This is especially true in ultra-long undersea tunnels, where multiple trains may be operating simultaneously. Failure to quickly and effectively control smoke and evacuate personnel to safe areas or the surface can easily lead to panic, resulting in stampedes and even non-fire train accidents.

[0003] Most long and large railway tunnels in China utilize a twin-hole, single-track design, and in-tunnel rescue stations often employ densely packed transverse tunnels or parallel pilot tunnels. When a train stops at an emergency rescue station in the event of a fire, passengers use the evacuation platform and transverse tunnels to enter unburned tunnels or evacuate outside the tunnel via parallel pilot tunnels for shelter. Smoke exhaust shafts and ventilation and exhaust facilities are installed near the rescue station to control smoke within the station and maintain wind speed at the transverse tunnel protective doors. This solution also requires the installation of inclined evacuation shafts and smoke exhaust shafts near the emergency rescue station.

[0004] It's also worth noting that the aforementioned solutions only provide a single evacuation route, underutilizing evacuation efficiency. Furthermore, while the system prioritizes ensuring the evacuation route, such as wind speed requirements at the cross-aisle protective doors, it lacks effective measures to prevent smoke from spreading into the tunnels at either end of the fire at the rescue station, compromising the safety of other trains and passengers within the extra-long tunnel. Summary of the Invention

[0005] In view of this, the present invention aims to propose a railway rescue station and personnel evacuation and smoke control method set up in a service tunnel, so as to improve the fire smoke exhaust efficiency and personnel evacuation efficiency when it is impossible to set up a smoke exhaust shaft or inclined shaft near the rescue station, thereby improving the overall disaster prevention and rescue level of the railway tunnel.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A railway rescue station with a service tunnel, comprising a service tunnel, an evacuation cross passage, a smoke exhaust duct, a fireproof partition sealing device, a jet fan, a wind speed and direction sensor, and a fan;

[0008] The service tunnel is arranged between two double-hole single-track tunnels, the evacuation transverse passage is located between the double-hole single-track tunnel and the service tunnel, and is arranged opposite to the evacuation platform in the double-hole single-track tunnel, for connecting the double-hole single-track tunnel and the service tunnel, and a protective door is provided in the evacuation transverse passage;

[0009] In the service tunnel, the fireproof partition sealing device is provided on the outside of both ends of the evacuation cross passage, and the smoke exhaust duct is provided between the double-hole single-track tunnel and the service tunnel. One end of the smoke exhaust duct is connected to the service tunnel, and the connection position is located outside the fireproof partition sealing device in the service tunnel. The other end of the smoke exhaust duct is connected to the double-hole single-track tunnel. The service tunnel serves as a smoke exhaust passage, and a smoke exhaust fire damper and a smoke exhaust port are provided in the smoke exhaust duct.

[0010] The jet fans are arranged on both sides of the evacuation platform in the double-hole single-track tunnel, the fans are arranged in the service tunnel, and there are multiple groups of wind speed and direction sensors, which are respectively arranged in the double-hole single-track tunnel and the evacuation cross channel. The monitoring values ​​can be converted into electrical signals and transmitted remotely.

[0011] Furthermore, both ends of the service tunnel are connected to open lines or ventilation shafts, and engineering maintenance vehicles and rescue vehicles can pass through the service tunnel.

[0012] Furthermore, the smoke exhaust fire damper is located in the smoke exhaust duct between the double-hole single-track tunnel and the service tunnel. The smoke exhaust fire damper is in a normally closed state and can be opened by a remote signal; there are multiple smoke exhaust ports, which are evenly distributed on the smoke exhaust duct in the double-hole single-track tunnel.

[0013] Furthermore, there are multiple evacuation transverse passages arranged side by side, and protective doors are provided in each of the evacuation transverse passages.

[0014] Furthermore, the fireproof partition sealing device is normally open during normal operation and can be closed via remote signal control. The fireproof partition sealing device uses fireproof rolling shutter doors and electrically controlled fiberglass reinforced plastic bi-folding / swinging doors. The circular cross-section of the service tunnel where the fireproof partition sealing device is located is divided into a rectangular cross-section that meets the dimensions of the fireproof partition sealing device through the civil wall. The columns and beams in the civil wall also serve as the columns and beams for the installation of the fireproof partition sealing device.

[0015] Furthermore, the fan can also be arranged in a machine room around the air shaft. The fan is composed of multiple groups of fans connected in parallel, and can realize smoke exhaust or air supply functions through remote control.

[0016] A method for evacuating personnel and controlling smoke at a railway rescue station, the process of which is as follows:

[0017] S1. Calculate and compare the distance between the nearest railway rescue station in front of the fire train and the safe evacuation exit;

[0018] S2. Based on the calculation result of step S1, determine the direction from the railway rescue station to the safe evacuation exit as the service tunnel evacuation direction;

[0019] S3. Remotely shut down the fireproof partition sealing device on the side of the rescue station away from the evacuation direction of the service tunnel;

[0020] S4. Remotely open the smoke and fire damper on the side of the rescue station away from the evacuation direction of the service tunnel;

[0021] S5: Remotely start the fan on the side away from the evacuation direction of the service tunnel, and the fan generates airflow in the exhaust direction; remotely start the fan on the side of the service tunnel evacuation direction, and the fan generates airflow in the supply direction;

[0022] S6. The rescue vehicle drives from the service tunnel to the rescue station in the evacuation direction;

[0023] S7. Guide passengers to wait and evacuate through evacuation platforms and evacuation cross passages to service tunnels and non-fire tunnels;

[0024] S8. Based on the values ​​monitored by the wind speed and direction sensors, the jet fans are regulated to ensure that the wind speed in the evacuation cross passage between the fire tunnel and the service tunnel is not less than 2 m / s, and the wind speed on both sides of the emergency rescue station used for evacuation in the fire tunnel is not less than the calculated critical wind speed, and the wind direction is blowing towards the fire train.

[0025] Furthermore, in step S1, after a fire occurs on a train and it is determined that the train stops at the emergency rescue station ahead for evacuation and rescue, the distance between the emergency rescue station and the safe evacuation exit is calculated respectively. The safe evacuation exit can be a station, a tunnel entrance, an inclined shaft or a vertical shaft for evacuation, etc.

[0026] Furthermore, in step S5, the smoke exhaust volume of the fan on the side away from the evacuation direction of the service tunnel is not less than the sum of the air volume flowing into the fire tunnel after all the protective doors in the evacuation cross channel are opened and the air intake volume at both ends of the fire tunnel that meets the critical wind speed, and is not less than the smoke generation of the fire train.

[0027] Furthermore, in step S8, the critical wind speed is calculated as follows:

[0028] ;

[0029] Where: V c - critical wind speed, in m / s;

[0030] g - acceleration due to gravity, in m / s 2 ;

[0031] H - tunnel height, in meters;

[0032] Q - the heat generated by the fire, in W;

[0033] - Density of surrounding air, in kg / m 3 ;

[0034] C p - Specific heat of air at a fixed pressure, in J / Kg·K;

[0035] A - net cross-sectional area of ​​the tunnel, in m 2 ;

[0036] T f - the temperature of the hot air, in K;

[0037] K g - Slope correction factor;

[0038] - Ambient air temperature, in K.

[0039] Compared with the prior art, the railway rescue station and personnel evacuation and smoke control method provided in the present invention have the following advantages:

[0040] The present invention provides an evacuation and rescue solution that does not rely on the installation of smoke exhaust shafts near railway tunnel emergency rescue stations. This solution directly utilizes the advanced pilot pit (service tunnel) used for geological exploration as a smoke exhaust path, avoiding the construction risks and increased project investment associated with the excessively large cross-section of the service tunnel caused by the installation of a smoke exhaust duct at the top of the service tunnel. Simultaneously, two evacuation routes, the service tunnel and the non-fire tunnel, are provided, improving fire evacuation efficiency. Furthermore, wind speed and direction sensors and jet fans are used to ensure smoke exhaust effectiveness while preventing smoke from spreading into the fire tunnel at both ends of the rescue station. This improves the safety of other trains in the extra-long tunnel and reduces the impact of smoke on tunnel facilities, facilitating the rapid resumption of operations after a disaster.
