Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0023] The following will combine with the attached drawings to make a detailed description of some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0024] Embodiment 1

[0025] Figure 1 It is a functional module diagram of a comprehensive linkage system for flood prevention in urban underground tunnels provided by the present utility model. As Figure 1 shown, the system includes: a water level monitoring facility 10, a flood prevention control facility 20, and a tunnel flood prevention facility 30.

[0026] The water level monitoring facility 10 is installed on the side wall at the lowest point of the tunnel pavement in the urban underground tunnel; the water level monitoring facility 10 is used to monitor the accumulated water depth at the lowest point of the tunnel pavement.

[0027] The flood prevention control facility 20 is respectively connected to the water level monitoring facility 10 and the tunnel flood prevention facility 30; the flood prevention control facility 20 is used to issue an emergency instruction to the tunnel flood prevention facility 30 according to the water depth interval where the accumulated water depth is located.

[0028] The tunnel flood prevention facility 30 is arranged at the flood prevention operation position of the urban underground tunnel; the tunnel flood prevention facility 30 is used to execute emergency measures according to the emergency instruction.

[0029] According to the composition of the comprehensive linkage system for flood prevention in urban underground tunnels provided in the embodiments of the present utility model in the above text and the function descriptions of each functional module, a water level monitoring facility 10 is set in the comprehensive linkage system to monitor the accumulated water depth at the lowest point of the road surface in the underground tunnel, and send the monitored data to the flood prevention control facility 20. After receiving the accumulated water depth, the flood prevention control facility 20 compares its size with the preset depth threshold. If it is determined that the accumulated water depth is not greater than the preset depth threshold, there is no need to make an emergency response to the current accumulated water situation. However, if it is determined that the accumulated water depth is greater than the preset depth threshold, it means that there is a risk of waterlogging in the underground tunnel. In order to reduce the risk of waterlogging, the flood prevention control facility 20 needs to issue corresponding emergency instructions according to the water depth interval where the current accumulated water depth is located, so that the tunnel flood prevention facility 30 executes emergency measures.

[0030] The corresponding relationship between the water depth range and the emergency instructions is exemplified below. For example, when the water accumulation depth is in the first water depth range (greater than the first depth and less than the second depth), the corresponding emergency instruction is to close the tunnel; when the water accumulation depth is in the second water depth range (greater than or equal to the second depth and less than the third depth), the corresponding emergency instruction is to close the road section to which the tunnel belongs; when the water accumulation depth is in the third water depth range (greater than or equal to the third depth), the corresponding emergency instruction is to close the road section and drain the water in the tunnel. Based on the above corresponding relationship, the flood prevention control facility 20 can determine the corresponding emergency instruction according to the water depth range where the actual water accumulation depth is located.

[0031] The embodiments of the present utility model do not specifically limit the number and values of the depth reference values, and users can set them according to actual needs. Optionally, three depth reference values are set, the first depth is 1 cm, the second depth is 15 cm, and the third depth is 30 cm.

[0032] The present utility model provides a comprehensive linkage system for flood prevention in urban underground tunnels, including: a water level monitoring facility 10, a flood prevention control facility 20, and a tunnel flood prevention facility 30. The water level monitoring facility 10 is installed on the side wall at the lowest point of the tunnel road surface in the urban underground tunnel, and is used to monitor the water accumulation depth at the lowest point of the tunnel road surface and send the monitoring result to the flood prevention control facility 20. The flood prevention control facility 20 issues an emergency instruction to the tunnel flood prevention facility 30 according to the water depth range where the water accumulation depth is located. The tunnel flood prevention facility 30 is arranged at the flood prevention operation position in the urban underground tunnel and is used to execute emergency measures according to the emergency instruction, so as to prevent the spread of floods and reduce the loss of tunnel waterlogging. The application of the present utility model can improve the safety, traffic smoothness and management efficiency of underground tunnels, and provide guarantee for the normal operation of urban traffic.

[0033] Optionally, as Figure 2 shown, the comprehensive linkage system further includes: a meteorological monitoring facility 40;

[0034] The meteorological monitoring facility 40 is arranged at a preset position on the ground of the urban underground tunnel; the meteorological monitoring facility 40 is used to monitor the meteorological data of the location where the urban underground tunnel is located.

[0035] The flood prevention control facility 20 is connected to the meteorological monitoring facility 40; the flood prevention control facility 20 is used to determine the flood risk information of the urban underground tunnel in a preset future time period according to the meteorological data, and display the flood risk information when the preset future time period arrives.

[0036] Specifically, in order to strengthen the ability to respond to extreme weather conditions such as heavy rainfall, the integrated linkage system can also add a function to monitor the meteorological data of the location where the urban underground tunnel is located, and send the monitored meteorological data to the flood prevention control facility 20. The flood prevention control facility 20 processes the meteorological data using the rainfall prediction method in the existing technology, and can determine the rainfall in the tunnel during a preset future time period. Then, according to the rainfall range where the rainfall is located, the corresponding flood risk information is determined. Once the starting time point of the preset future time period arrives, the above flood risk information is displayed, so that the system user, that is, the user of the integrated linkage system, which can also be understood as the tunnel management personnel, can make corresponding preparations for flood prevention in the tunnel in advance.

[0037] The corresponding relationship between the rainfall range and the flood risk information is exemplified below. For example, if the rainfall range is greater than 1 cm and less than 15 cm, the corresponding flood risk information is an emergency linkage blue warning; if the rainfall range is greater than or equal to 15 cm and less than 30 cm, the corresponding flood risk information is an emergency linkage yellow warning; if the rainfall range is greater than or equal to 30 cm, the corresponding flood risk information is an emergency linkage red warning. Obviously, as the rainfall increases, the risk level of the above three disaster warning information also increases.

[0038] The flood prevention control facility 20 is also provided with a database, which stores the corresponding relationship between multiple groups of rainfall ranges and historical control strategies. Therefore, once the rainfall range where the predicted rainfall is located is determined, the corresponding historical control strategy can also be fed back to the system user, so as to provide a reference strategy for the system user to prevent the tunnel from being flooded.

[0039] Furthermore, the flood prevention control facility 20 can also be communicatively connected to the emergency response system of the relevant department (that is, the external emergency response system). Thus, after the flood prevention control facility 20 determines the flood risk information corresponding to the rainfall range, the flood risk information is synchronously sent to the external emergency response system to work in coordination with the external emergency response system to ensure that actions can be taken promptly to mitigate the possible impact of tunnel flooding.

[0040] In this embodiment, the meteorological data, such as rainfall, wind speed, temperature, humidity, etc., the meteorological data collected by the meteorological monitoring facility 40 can be set according to the input data required by the rainfall prediction method used by the flood prevention control facility 20. Similarly, the duration of the above preset future time period is also adjusted following the rainfall prediction method. The present utility model embodiment does not specifically limit the rainfall prediction method, and the user can choose any method in the existing technology. For example, the method disclosed in the paper "Research on Rainfall Prediction Based on the CatBoost Model" can be referred to.

[0041] Optionally, asFigure 3 As shown in Figure 3 , the meteorological monitoring facility 40 includes: a weather station 401.

[0042] The weather station 401 is set at a preset above-ground position of the urban underground tunnel and is connected to the flood prevention control facility 20; among them, the preset above-ground position can be selected near the tunnel entrance or exit.

[0043] The water level monitoring facility 10 includes: an electronic water gauge 101.

[0044] The electronic water gauge 101 is installed on the side wall at the lowest point of the tunnel road surface of the urban underground tunnel and is connected to the flood prevention control facility 20.

[0045] In order to enhance the flood prevention monitoring ability, at least one electronic water gauge 101 can also be set in the open area where the tunnel exits to the ground and is connected to the tunnel, and the water depth data monitored by it is sent to the flood prevention control facility 20. Once the water depth at any place is greater than the preset depth threshold, the integrated linkage system will start corresponding emergency measures. The embodiments of the present utility model do not specifically limit the reporting period of the monitoring data of the weather station 401 and the electronic water gauge 101, and users can set it according to actual needs. For example, in rainy weather, it can be configured to report in real time, and in sunny weather, it can be configured to report periodically.

[0046] Since the electronic water gauge 101 is an electronic device that automatically monitors the water depth and reports it, the reported data may deviate due to equipment failures. Therefore, in order to further improve the reliability of the integrated linkage system, the water level monitoring facility 10 further includes: a water level warning line 102 and a water level camera 103.

[0047] The water level warning line 102 is set at a preset height from the lowest point of the tunnel road surface and is used to indicate the depth range where the water depth at the lowest point of the tunnel road surface is located.

[0048] The water level camera 103 is set at a designated position in the urban underground tunnel, and the water level camera 103 is used to take images of the water level warning line.

[0049] The flood prevention control facility 20 is connected to the water level camera 103; the flood prevention control facility 20 is used to display a verification water depth prompt message when it is determined that the depth range indicated by the water level warning line 102 does not match the water depth monitored by the electronic water gauge 101 according to the water level warning line image.

[0050] The embodiments of the present utility model do not specifically limit the preset height of the water level warning line 102 from the ground, and users can set it according to actual needs. Optionally, the preset height is the same as the values of the above-mentioned first depth, second depth, and third depth. If referring to the examples of the first depth, second depth, and third depth above, the water level warning line 102 is respectively set at 1 cm, 15 cm, and 30 cm from the ground at the lowest point of the tunnel.

[0051] If the accumulated water depth monitored by the electronic water level gauge 101 is not within the depth range indicated by the water level warning line 102, it indicates that there is an abnormality in the indication of the electronic water level gauge 101 or the water level warning line 102. Therefore, it is necessary to prompt the system user to verify the accumulated water depth in the tunnel. When the system user conducts the verification, they can observe the water level in the tunnel through a video monitoring device connected to the water level camera 103. In addition, the setting of the water level warning line 102 can also facilitate the drivers and passengers inside the tunnel to intuitively perceive the water accumulation situation on the road surface in the tunnel.

[0052] Optionally, the flood prevention control facility 20 includes: a central processing unit and a display;

[0053] The central processing unit is the core data processing module of the flood prevention control facility 20, and is used to process the data sent by the water level monitoring facility 10 and the meteorological monitoring facility 40.

[0054] The display is connected to the central processing unit, and is used to display the data received by the central processing unit and the data sent outwards.

[0055] That is to say, the setting of the display enables information such as the accumulated water depth, the image of the water level warning line, meteorological data, as well as the emergency instructions, flood risk information, and historical control strategies output by the flood prevention control facility 20 to be presented to the system user intuitively.

[0056] Optionally, the flood prevention control facility 20 further includes: a memory; the memory is connected to the central processing unit, and is used to record the actions executed by the central processing unit.

[0057] Specifically, the memory can record the data transmission and data processing processes of the integrated linkage system for subsequent data traceability. And based on the data stored in the memory, the system user can also write the rainfall amount during each rainfall, as well as the corresponding traffic flow, the number of water pumps, the tunnel pumping time, and tunnel control parameters such as flow limiting, control, or closure when executing the emergency response into the database to guide future similar rainfall events.

[0058] Optionally, as Figure 4 shown, the tunnel flood prevention facility 30 includes: a warning facility 301, a water blocking facility 302, a drainage facility 303, and a road closure facility 304.

[0059] The warning facility 301 is installed at the entrance and exit of the urban underground tunnel; the warning facility 301 is used to output warning information corresponding to the emergency instruction.

[0060] The water-blocking facility 302 is installed at the entrance and exit of the urban underground tunnel; it is used to prevent road waterlogging from entering the tunnel.

[0061] The drainage facility 303 is installed inside the urban underground tunnel and is used to drain the tunnel waterlogging.

[0062] The road closure facility 304 is installed at the entrance and exit of the urban underground tunnel and its affiliated road section; it is used to close the tunnel and its affiliated road section.

[0063] Among them, the warning facility 301 includes at least one of the following: traffic signal lights, electronic information boards, notice boards, and broadcasts. The setting of the warning facility 301 can effectively convey the tunnel waterlogging risk information to the personnel and vehicles near the tunnel.

[0064] The water-blocking facility 302 includes at least one of the following: water-blocking sandbags, water baffle plates, and flood prevention doors. The water-blocking facility 302 can effectively protect the urban underground tunnel from the threat of waterlogging.

[0065] The drainage facility 303 includes: water pumps. When the flood prevention and control facility 20 outputs an emergency instruction to drain the tunnel waterlogging, the instruction carries the number of water pumps to be called, and the number of water pumps to be called is determined according to the rainfall and the pumping capacity of the water pumps. The number of water pumps to be called can also be dynamically adjusted according to the dynamically changing water depth inside the tunnel, so as to drain the water inside the tunnel as soon as possible.

[0066] The road closure facility 304 includes at least one of the following: conical warning caps, crash trucks, road gates, and no-entry signs. The road closure facility 304 can quickly close the tunnel and the entrance and exit of the tunnel's affiliated road section when a waterlogging occurs in the tunnel.

[0067] The following is an example of an application of the integrated linkage system. The meteorological monitoring facility 40 continuously monitors the meteorological data at the preset positions on the ground of the urban underground tunnel and sends the meteorological data to the flood prevention and control facility 20. The flood prevention and control facility 20 determines that the waterlogging risk information for the preset future time period is an emergency linkage red warning based on the meteorological data. And when the preset future time period arrives, it notifies the maintenance duty or emergency duty personnel to immediately arrive at the tunnel entrance, make preparations for road closure, water blocking, increased drainage, etc., and report to the supervision department.

[0068] The flood prevention control facility 20 collects the water depth at the lowest point of the tunnel road surface every two seconds, and determines whether the water depth at this moment is higher than 1 cm. If it is lower than 1 cm, the water level monitoring facility 10 continues to monitor the water depth. If it is higher than 1 cm, an emergency linkage blue warning is initiated, and the local traffic police department and the supervision department are immediately contacted and a road closure requirement is proposed. The warning signs, electronic information boards, and broadcasts in the tunnel flood prevention facility 30 simultaneously prompt the warning information of "Operation inside the road, it is recommended to detour", and use road closure facilities such as crash trucks and conical warning caps in combination with traffic lights to close each lane one by one. If it is higher than 15 cm, an emergency linkage yellow warning is initiated, and a report is immediately made to the local traffic police department and the supervision department, and the road is completely closed using road closure facilities such as no-entry signs and road gates in combination with traffic lights. At the same time, the warning signs, electronic information boards, and broadcasts simultaneously prompt "Road closure operation, no entry". If it is higher than 30 cm, an emergency linkage red warning is initiated, and all vehicles including emergency vehicles are strictly prohibited from entering the water accumulation area. Immediately, water blocking facilities such as emergency water blocking boards and water blocking sandbags are added to block the water, and drainage facilities such as temporary drainage pumps are started to increase the strong drainage flow rate.

[0069] In summary, the implementation and application of the comprehensive linkage system provided by the embodiments of the present invention can achieve comprehensive monitoring and management of underground tunnels, promptly discover and alarm flood events, ensure that emergency measures are taken as early as possible, effectively prevent and reduce underground tunnel flood events, ensure the safe operation of the tunnels, reduce accidents and disasters caused by floods, and contribute to improving the urban management level and enhancing the urban disaster resistance ability.
