[0002] Tunnel bricks have a wide range of applications and are the preferred decorative materials for buildings such as tunnel traffic, high-speed prompts, and tunnel turns. However, once they fall off, they will cause serious traffic accidents. Therefore, in order to achieve the maintenance and management of tunnels, in the invention patent application CN202211000361.7 "Tunnel structure property prediction method, device, computer equipment and storage medium", the key disease indicators that affect the performance of the tunnel structure are sorted out, and the tunnel structure is finely predicted according to the key disease indicators and various influencing factors, so as to achieve targeted maintenance and management. However, it is not difficult to find the following technical problems through analysis:

[0003] For tunnels, especially large tunnels, the number of tunnel bricks inside is very large. Due to the differences in the placement of different tunnel bricks, the probability of traffic accidents when they fall varies greatly. Therefore, if differentiated maintenance management strategies cannot be generated based on the differences in the placement of tunnel bricks, it is impossible to improve the reliability of maintenance management while reducing the difficulty of maintenance management.

[0004] In view of the above technical problems, the present invention provides a tunnel brick maintenance management method, system and cutting device. Summary of the invention

[0040] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0041] The falling of tunnel bricks will not only affect the smoothness of traffic to a certain extent, but also have a certain impact on the driving safety of vehicles. Therefore, it is necessary to generate differentiated tunnel brick maintenance and inspection strategies based on the traffic volume of different tunnels and the risk of tunnel brick falling to ensure the safety of tunnel bricks.

[0042] Specific:

[0043] Drop impact coefficient: It is determined based on the historical lane flow data of the lane affected when the tunnel brick falls. Specifically, the drop impact coefficient can be determined based on the average value of the historical lane flow. Specifically, it is determined based on the ratio of the average value of the historical lane flow to the preset flow. For example, if the average value of the historical lane flow is 1,000 vehicles, the drop impact coefficient is 1,000 divided by 10,000, which is 0.1.

[0044] Falling risk: It is determined according to the stress condition of the tunnel brick, specifically, the product of the number of falling tunnel bricks with similar stress condition to the tunnel brick and the preset proportional coefficient. For example, if the number of falling bricks is 20, the falling risk is 20 multiplied by 0.1, which is 0.2.

[0045] The maintenance inspection strategy includes a maintenance inspection cycle, and the maintenance inspection strategy is specifically determined according to a preset maintenance inspection strategy that matches the number of tunnel bricks and the drop impact coefficient. Example

[0046] To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a method for tunnel brick maintenance management is provided, which specifically includes:

[0047] S1 determines the lane affected by the fall of the tunnel brick, and uses the historical lane flow data of the lane affected by the fall to determine the fall influence coefficients of different tunnel bricks, and judges whether the fall influence coefficients of the tunnel bricks meet the requirements. If so, proceed to step S3, if not, proceed to the next step;

[0048] S2: determining the stress condition of the tunnel brick based on the setting position of the tunnel brick, and when it is determined according to the stress condition that the falling risk of the tunnel brick meets the requirement, proceeding to the next step;

[0049] S3 determines the risk type of the tunnel brick using the drop impact coefficient of the tunnel brick, and when the number of tunnel bricks of the risk type determined by using a preset quantity threshold does not meet the requirement, proceeds to the next step;

[0050] S4 obtains the historical lane flow of the tunnel in different lanes, and determines the maintenance and detection strategy of the tunnel bricks in different risk types in combination with the number of tunnel bricks in different risk types and the drop impact coefficient of the tunnel bricks. When it is determined that the tunnel bricks are abnormal based on the maintenance and detection strategy, the tunnel bricks are replaced using the size of the tunnel bricks and the cutting device.

[0051] Furthermore, the lane affected by the fall of the tunnel brick is determined according to the setting position of the tunnel brick. Specifically, the lane affected by the fall of the tunnel brick is determined according to the setting position of the tunnel brick, and the lane affected after the fall is used as the lane affected by the fall of the tunnel brick.

[0052] Specifically, the historical lane flow data is determined based on the analysis result of the monitoring data of the monitoring device of the lane affected by the fall.

[0053] It should be noted that if Figure 2 As shown, the method for determining the drop influence coefficient of the tunnel brick is:

[0054] Determine the historical duration ratio of the lane affected by the drop at different vehicle spacings according to the historical lane flow data of the lane affected by the drop, and determine the vehicle driving probability at different vehicle spacings based on the historical duration ratio at different vehicle spacings;

[0055] Determine the drop impact weight value at different vehicle spacings, and determine the drop lane impact coefficient of the drop impact lane in combination with the vehicle driving probabilities at different vehicle spacings;

[0056] The setting position of the tunnel brick is used to determine the area ratio of the tunnel brick and different drop-influence lanes under vertical projection, and the area ratio is used to determine the influence weight values ​​of different drop-influence lanes. The drop influence coefficient of the tunnel brick is determined based on the drop lane influence coefficients and influence weight values ​​of different drop-influence lanes.

[0057] Further, the drop influence coefficient of the tunnel brick is determined based on the drop lane influence coefficients and influence weight values ​​of different drop influence lanes, specifically including:

[0058] The lane influence coefficients of different drop impact lanes are determined by multiplying the drop lane influence coefficients of different drop impact lanes and the influence weight value, and the drop impact coefficient of the tunnel brick is determined according to the sum of the lane influence coefficients of different drop impact lanes.

[0059] It can be understood that the value range of the drop impact coefficient of the tunnel brick is between 0 and 1, wherein when the drop impact coefficient of the tunnel brick is greater than the preset impact coefficient, it is determined that the drop impact coefficient of the tunnel brick does not meet the requirements.

[0060] It should also be noted that the method for determining the drop influence coefficient of the tunnel brick is:

[0061] Determine the average daily traffic volume of the drop-affected lane according to the historical lane traffic volume data of the drop-affected lane, and determine the preset drop-affected coefficient corresponding to the drop-affected lane based on the average daily traffic volume;

[0062] Using the setting position of the tunnel brick, determine the area ratio of the tunnel brick and different drop-affected lanes under vertical projection, and using the area ratio to determine the influence weight value of different drop-affected lanes;

[0063] The fall impact coefficient of the tunnel brick is determined based on preset fall impact coefficients and impact weight values ​​corresponding to different fall impact lanes.

[0064] In another embodiment, the method for determining the drop impact coefficient of the tunnel brick is:

[0065] S11 determines the historical traffic volume of the drop-affected lane on different dates according to the historical lane traffic volume data of the drop-affected lane, takes the date when the historical traffic volume is greater than the preset traffic volume as the busy date, and determines whether there is a drop-affected lane with a busy date. If yes, proceed to the next step, if not, proceed to step S14;

[0066] S12 determines whether there is a drop lane whose number of busy dates accounts for more than a preset proportion. If so, proceed to the next step; if not, proceed to step S14;

[0067] S13 determines the driving busy coefficient by using the proportion of the number of busy days of different falling lanes and the historical traffic flow on different busy days, and judges whether the driving busy coefficient meets the requirements. If so, proceeds to the next step; if not, determines the falling influence coefficient of the tunnel brick by using the driving busy coefficient;

[0068] S14 determines the vehicle driving probability of the drop-affected lane at different vehicle spacings based on the historical duration ratios at different vehicle spacings, determines the drop-affected weight values ​​at different vehicle spacings, and determines the drop-affected lane influence coefficient of the drop-affected lane in combination with the vehicle driving probability at different vehicle spacings;

[0069] S15 uses the setting position of the tunnel brick to determine the area ratio of the tunnel brick and different drop-influence lanes under vertical projection, and uses the area ratio to determine the influence weight values ​​of different drop-influence lanes, and determines the drop influence coefficient of the tunnel brick based on the drop lane influence coefficients and influence weight values ​​of different drop-influence lanes.

[0070] Furthermore, the stress condition of the tunnel brick is determined according to the stress numerical simulation result of the setting position of the tunnel brick, specifically including the stress data in different preset directions.

[0071] It should be noted that if Figure 3 As shown, the method for determining the falling risk of the tunnel brick is:

[0072] Determine the force data of the tunnel brick in different preset directions by using the force conditions, and determine the initial falling risk of the tunnel brick according to the force data in different preset directions;

[0073] Based on the force data in different preset directions, the deviations from the force data of different historical dropped tunnel bricks in different preset directions are determined, and based on the deviations from the force data in different preset directions, the force deviation coefficients from different historical dropped tunnel bricks are determined;

[0074] Determine the tunnel bricks at similar positions of different historically dropped tunnel bricks by the installation positions of different historically dropped tunnel bricks, and determine the drop risk compensation factor under different historically dropped tunnel bricks by the product of the number ratio of different historically dropped tunnel bricks in the tunnel bricks at similar positions and the force deviation coefficient of the tunnel brick;

[0075] The fall risk of the tunnel brick is determined based on the sum of the fall risk compensation factor and the initial fall risk under different historical fall tunnel bricks.

[0076] Further, when the falling risk of the tunnel brick is greater than a preset risk threshold, it is determined that the falling risk of the tunnel brick does not meet the requirement.

[0077] It is understandable that when the falling risk of the tunnel brick does not meet the requirements, the tunnel brick needs to be subjected to maintenance and inspection.

[0078] It should also be noted that the method for determining the falling risk of the tunnel brick is:

[0079] Determine the force data of the tunnel brick in different preset directions by using the force conditions, determine the deviation from the force data of different historical dropped tunnel bricks in different preset directions based on the force data in different preset directions, and determine the force deviation coefficient from different historical dropped tunnel bricks based on the deviation from the force data in different preset directions;

[0080] The force deviation coefficient is used to determine the tunnel bricks with similar force among the tunnel bricks that have fallen historically, and the falling risk of the tunnel brick is determined according to the number of the tunnel bricks with similar force.

[0081] It should also be noted that the method for determining the falling risk of the tunnel brick is:

[0082] S21 uses the force conditions to determine the force data of the tunnel brick in different preset directions, determines the deviations from the force data of different historical dropped tunnel bricks in different preset directions based on the force data in different preset directions, and determines the force deviation coefficients from different historical dropped tunnel bricks based on the deviations from the force data in different preset directions;

[0083] S22 determines the initial falling risk of the tunnel brick according to the force data in different preset directions, and judges whether the initial falling risk of the tunnel brick is greater than the risk limit value. If so, proceed to the next step; if not, proceed to step S25;

[0084] S23 determines the tunnel bricks with similar forces among the tunnel bricks that have fallen in history by using the force deviation coefficient, and judges whether the number of the tunnel bricks with similar forces meets the requirement, if so, proceeds to the next step, if not, determines that the falling risk of the tunnel brick does not meet the requirement;

[0085] S24 determines the similar position tunnel bricks of different similar force-bearing tunnel bricks through the installation positions of different similar force-bearing tunnel bricks, and judges whether there are similar force-bearing tunnel bricks whose quantity ratio among the similar position tunnel bricks does not meet the requirements, if not, proceeds to the next step, if yes, determines that the falling risk of the tunnel brick does not meet the requirements;

[0086] S25 determines the tunnel bricks at similar positions of different historical dropped tunnel bricks through the installation positions of different historical dropped tunnel bricks, determines the drop risk compensation factor under different historical dropped tunnel bricks through the product of the number proportion of different historical dropped tunnel bricks in the tunnel bricks at similar positions and the force deviation coefficient of the tunnel brick, and determines the drop risk of the tunnel brick based on the drop risk compensation factor under different historical dropped tunnel bricks and the sum of the initial drop risk.

[0087] Furthermore, the method for determining the risk type of the tunnel brick is:

[0088] The risk type of the tunnel brick is determined by using the fall impact coefficient of the tunnel brick and the fall impact coefficient intervals corresponding to different risk types.

[0089] Specifically, the preset quantity threshold is determined according to a preset quantity threshold corresponding to the risk type of the tunnel brick.

[0090] It should be noted that, when the number of tunnel bricks of the risk type is greater than a preset number threshold, it is determined that the number of tunnel bricks of the risk type does not meet the requirement.

[0091] It can be understood that when the number of tunnel bricks of the risk type meets the requirement, the tunnel bricks of the risk type are all subjected to maintenance inspection.

[0092] Specifically, Figure 4 As shown, the method for determining the maintenance and detection strategy of the tunnel brick is:

[0093] Determine the average daily traffic volume of the tunnel based on the historical lane traffic volume of the tunnel in different lanes, and determine the detection ratio of tunnel bricks of different risk types based on the average daily traffic volume;

[0094] The number of tunnel bricks of the risk type to be inspected is determined based on the number of tunnel bricks of the risk type and the tunnel brick inspection ratio, and the maintenance inspection strategy for the tunnel bricks in the risk type is determined based on the inspection number and the drop impact coefficient.

[0095] Specifically, the maintenance and inspection strategy includes a maintenance and inspection cycle.

[0096] Specifically, the maintenance inspection strategy for tunnel bricks in the risk type is determined based on the number of inspections and the drop impact coefficient, specifically including:

[0097] The comprehensive risk factor in the risk type is determined based on the detection quantity and the drop impact coefficient, and the maintenance detection strategy for the tunnel bricks in the risk type is determined based on the comprehensive risk factor.

[0098] It should be further explained that the method for determining the maintenance and inspection strategy of the tunnel bricks is:

[0099] Determine whether the middle value of the drop impact coefficient interval corresponding to the risk type is less than the preset coefficient threshold value. If so, determine the maintenance inspection strategy of the tunnel bricks in the risk type using the preset inspection ratio and the drop impact coefficient. If not, proceed to the next step.

[0100] Determine the traffic volume of the tunnel on different dates based on the historical lane traffic volume of the tunnel in different lanes, and judge whether the traffic volume of the tunnel on different dates is less than a preset traffic volume threshold. If yes, determine the maintenance inspection strategy of the tunnel bricks in the risk type using the preset inspection ratio and the drop influence coefficient. If no, proceed to the next step.

[0101] Determine whether the proportion of days with a traffic volume greater than a preset traffic volume threshold is greater than a preset day proportion threshold. If so, perform maintenance inspection on all tunnel bricks in the risk type. If not, proceed to the next step.

[0102] Determine the average daily traffic volume of the tunnel by using the historical lane traffic volume of the tunnel in different lanes, and determine the number of tunnel bricks detected of the risk type by using the average daily traffic volume, and judge whether the number of tunnel bricks of the risk type is less than the number of tunnel bricks detected. If so, perform maintenance detection on all tunnel bricks of the risk type. If not, proceed to the next step.

[0103] The maintenance inspection strategy for tunnel bricks in the risk type is determined based on the number of tunnel brick inspections and the drop impact coefficient. Example

[0106] The impact coefficient evaluation module is responsible for determining the lane affected by the fall of the tunnel bricks, and determining the fall impact coefficients of different tunnel bricks using the historical lane flow data of the lane affected by the fall;

[0107] The falling risk assessment module is responsible for determining the stress condition of the tunnel brick based on the setting position of the tunnel brick, and determining whether the falling risk of the tunnel brick meets the requirements according to the stress condition;

[0108] The risk assessment module is responsible for determining the risk type of the tunnel brick using the drop impact coefficient of the tunnel brick, and determining whether the number of tunnel bricks of the risk type meets the requirement using a preset quantity threshold;

[0109] The replacement processing module is responsible for obtaining the historical lane flow of the tunnel in different lanes, and determining the maintenance detection strategy of tunnel bricks in different risk types based on the number of tunnel bricks in different risk types and the drop impact coefficient of tunnel bricks. When it is determined that the tunnel brick is abnormal based on the maintenance detection strategy, the size of the tunnel brick and the cutting device are used to replace the tunnel brick. Example
