[0001] This application relates to the field of tunnel construction technology, and in particular to a method, system, equipment and medium for generating tunnel construction plans. Background Technology

[0002] With the rapid development of the national economy and the continuous improvement of transportation infrastructure, tunnel construction technology has made remarkable progress. From the initial manual excavation to today's mechanized and automated construction, tunnel construction has achieved great improvements in speed, quality, and safety.

[0003] Tunnel construction is usually managed according to a construction cycle. Generally, the progress of a week or a month is predicted and a corresponding annual or monthly construction plan is formulated. Each month, the construction plan for the following month is formulated based on the progress.

[0004] Currently, tunnel construction plans are mostly formulated in advance based on the construction experience of technical personnel. Due to a lack of accuracy and flexibility, when faced with unexpected geological conditions, the inability to adjust the construction plan in a timely manner may cause delays in the construction schedule. Therefore, in order to improve construction efficiency, how to rationally coordinate and plan the construction plan according to the actual conditions of the construction site is an urgent problem to be solved. Summary of the Invention

[0005] In order to rationally coordinate and plan the construction schedule based on the actual conditions of the construction site, this application provides a method, system, equipment and medium for generating tunnel construction plans.

[0006] Firstly, this application provides a method for generating a tunnel construction plan, employing the following technical solution: A method for generating a tunnel construction plan, the method comprising: Obtain geological condition data for the current working face station; the geological condition data includes surrounding rock type, specific geological condition monitoring data, and hazardous gas monitoring data; Based on a pre-set construction method library, the corresponding construction method is determined according to the surrounding rock type; Based on the monitoring data of the specific geological conditions and the monitoring data of harmful gases, the corresponding specific construction measures are determined; The construction method is adjusted according to the specific construction measures to generate corresponding construction procedures. Based on the surrounding rock type and construction method, determine the preset cycle advance of the working face pile number; Based on the surrounding rock type, construction procedure, and preset cycle advance, the corresponding predicted construction operation time is determined; The system receives construction organization information input by the user, and generates a corresponding tunnel construction plan by combining the construction procedures and the predicted duration of construction operations.

[0007] By adopting the above technical solution, geological data such as the surrounding rock type, specific geological condition monitoring data, and hazardous gas monitoring data of the current tunnel face pile number are obtained from advanced geological forecast data or construction design data to comprehensively understand the geological conditions of the construction area. Specifically, the corresponding standard construction method can be obtained based on the surrounding rock type to ensure that the construction method matches the geological conditions; the specific construction measures can be obtained based on the specific geological condition monitoring data and hazardous gas monitoring data to reduce construction risks; the construction method can be adjusted according to the specific construction measures to ensure the smooth progress of the construction process; the preset cycle advance of the tunnel face pile number and the corresponding construction operation prediction time are determined based on the surrounding rock type and construction method; and the corresponding tunnel construction plan can be generated by combining the construction operation prediction time, the construction organization information input by the user, and the adjusted construction procedures.

[0008] By accurately acquiring geological data, flexibly selecting construction methods based on the actual geological conditions at the construction site, adjusting the procedures with specific construction measures, rationally determining the cycle advance and predicted construction operation time, and generating a tunnel construction plan in conjunction with construction organization information, construction efficiency was improved, construction risks were reduced, and the smooth progress of tunnel construction was ensured.

[0009] Optionally, the steps for determining specific construction measures based on the monitoring data of the specific geological conditions and the monitoring data of harmful gases include: Based on the monitoring data of the specific geological conditions and the monitoring data of harmful gases, it is determined whether there are any specific geological conditions and / or excessive harmful gases. If so, the corresponding severity level is determined based on the pre-set construction measures database and the monitoring data of the specific geological conditions and / or the monitoring data of harmful gases. Based on the specific geological conditions and / or the severity level of the hazardous gas exceedance, corresponding specific construction measures will be determined.

[0010] By adopting the above technical solutions, specific geological conditions and excessive levels of harmful gases are classified into different severity levels. Corresponding treatment measures are determined according to the severity level, which facilitates the implementation of appropriate measures in a targeted manner based on specific circumstances, thereby ensuring the safety of tunnel construction and the smooth progress of the construction plan.

[0011] Optionally, after generating the corresponding tunnel construction plan, the following may also be included: Real-time monitoring of specific geological conditions and harmful gas monitoring data at the working face pile number; To determine whether there have been changes in specific geological conditions and / or the extent of harmful gas exceedances; If so, then the specific construction measures after the change shall be determined based on the specific geological conditions and / or the level of harmful gas exceeding the standard. The construction procedures of the tunnel construction plan are adjusted according to the changed specific construction measures in order to regenerate the tunnel construction plan.

[0012] By adopting the above technical solution, during the process of generating and carrying out construction according to the construction plan, the specific geological conditions and the level of harmful gas exceedances at the current construction location can be monitored in real time. It can also be determined whether there are any changes compared to the last time the construction plan was generated. By determining the specific construction measures after the changes and adjusting the construction plan, changes can be responded to in a timely manner, ensuring the safety and smooth progress of tunnel construction, thereby improving construction quality, reducing risks, and effectively controlling the construction progress.

[0013] Optionally, the step of determining the corresponding predicted construction operation time based on the surrounding rock type, construction procedure, and preset cycle advance includes: Data preprocessing is performed on the surrounding rock type, construction procedure, and preset cycle advance to obtain the corresponding model input values; The model input values ​​are input into a pre-trained construction operation duration prediction model to obtain the predicted construction operation duration.

[0014] By adopting the above technical solution, the construction operation time can be predicted by using a neural network model based on factors affecting the tunnel construction operation time, such as the surrounding rock type, construction procedure, and preset cycle advance.

[0015] Optionally, the plan generation method further includes: Receive the actual duration of the construction operation input by the user; The predicted duration of the construction operation is corrected based on the actual duration of the construction operation. The tunnel construction plan is regenerated based on the revised predicted construction operation duration.

[0016] By adopting the above technical solution, when the actual duration of the construction work exceeds or precedes the predicted duration at the end of each construction cycle, the predicted duration is corrected in real time and a new construction plan is generated. By comparing the actual construction situation with the construction plan, it is convenient to adjust and optimize the construction progress and resource allocation in a timely manner, thereby improving the accuracy and operability of the construction plan.

[0017] Optionally, after generating the tunnel construction plan, the following may also be included: Based on the tunnel construction plan, the predicted construction operation time is obtained through analysis. Determine whether the predicted construction operation duration exceeds a preset construction duration threshold; If so, a project overdue warning signal will be sent to the user terminal.

[0018] By adopting the above technical solution, the predicted construction operation time is compared with the preset construction time threshold to help relevant personnel understand the construction progress in a timely manner, warn of potential risks of construction delays, and take corresponding countermeasures, such as adjusting the construction plan and increasing resources, to ensure that the construction proceeds as planned and avoid delays and increased costs.

[0019] Secondly, this application provides a tunnel construction plan generation system, which adopts the following technical solution: A tunnel construction plan generation system, the plan generation system comprising: The geological condition data acquisition module is used to acquire geological condition data for the current working face station; the geological condition data includes surrounding rock type, specific geological condition monitoring data, and hazardous gas monitoring data. The construction method determination module is used to determine the corresponding construction method based on the surrounding rock category, according to a preset construction method library. The specific construction measures determination module is used to determine the corresponding specific construction measures based on the monitoring data of the specific geological conditions and the monitoring data of harmful gases. The construction procedure generation module is used to adjust the construction method according to the specific construction measures and generate the corresponding construction procedure. The preset cycle advance determination module is used to determine the preset cycle advance of the working face pile number based on the surrounding rock type and construction method.

The tunnel construction plan generation module is used to receive construction organization information input by the user, and generate a corresponding tunnel construction plan by combining the construction procedures and the predicted duration of construction operations.

[0020] By adopting the above technical solutions, accurate geological data can be obtained, construction methods can be flexibly selected based on the actual geological conditions at the construction site, specific construction measures can be taken to adjust the procedures, and the cycle advance and construction operation prediction time can be reasonably determined. In addition, a tunnel construction plan can be generated by combining construction organization information, which improves construction efficiency, reduces construction risks, and ensures the smooth progress of tunnel construction.

[0021] Optionally, the plan generation system further includes: The monitoring module is used to monitor specific geological conditions and harmful gas data at the working face station in real time. The judgment module is used to determine whether there are changes in specific geological conditions and / or the level of harmful gas exceedances; if so, it outputs the judgment result that there are changes. The specific construction measures determination module is also used to determine the changed specific construction measures based on the specific geological conditions and / or the level of harmful gases exceeding the standard. The tunnel construction plan generation module is also used to adjust the construction procedures of the tunnel construction plan according to the changed specific construction measures, so as to regenerate the tunnel construction plan.

[0022] By adopting the above technical solution, during the process of generating and carrying out construction according to the construction plan, the specific geological conditions and the level of harmful gas exceedances at the current construction location can be monitored in real time. It can also be determined whether there are any changes compared to the last time the construction plan was generated. By determining the specific construction measures after the changes and adjusting the construction plan, changes can be responded to in a timely manner, ensuring the safety and smooth progress of tunnel construction, thereby improving construction quality, reducing risks, and effectively controlling the construction progress.

[0031] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-5 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0032] This application discloses a method for generating tunnel construction plans.

[0033] Reference Figure 1 A method for generating a tunnel construction plan, the method comprising: Step S101: Obtain geological condition data for the current working face pile number; wherein, the geological condition data includes surrounding rock type, specific geological condition monitoring data, and harmful gas monitoring data; In tunnel construction, the tunnel face refers to the working face that progresses from the entrance towards the exit according to specific procedures and methods. The location of the tunnel face is usually determined by stationing, a numbering system used to identify locations in engineering projects such as tunnels or roads. Construction workers use the stationing of the tunnel face to determine the current construction location and accordingly assess geological conditions, determine construction methods, and control the construction progress.

[0034] It should be noted that the advancement and construction of the tunnel face is a cyclical process, repeated continuously until the designed exit position of the tunnel is reached. At the tunnel face, construction workers perform excavation, support, drainage, and ventilation procedures according to construction technology and design requirements. Once the procedures and operations at the current face are completed, the face will advance a certain distance to the next face. By monitoring the position and progress of the tunnel faces, tunnel construction can be effectively managed and controlled, ensuring the smooth progress of both construction quality and schedule.

[0035] Geological data can be obtained through advanced geological forecasting data or construction design data. During the acquisition of geological data, if advanced geological forecasting data exists, it is obtained directly from it; otherwise, the geological data in the construction design data prevails. In one embodiment of this application, the construction design data is the result of geological surveys conducted during the design phase, including the surrounding rock type within a certain chainage range (starting chainage - ending chainage), specific geological conditions (such as water inrush), and hazardous gas conditions (such as methane). As tunnel construction progresses, this data will gradually be replaced by advanced geological forecasting data.

[0036] In some embodiments, advanced geological forecast data refers to data used in tunnel construction to predict and assess the surrounding rock and strata conditions in front of the tunnel face before construction, using modern geological exploration techniques and analysis methods. This data includes information such as surrounding rock type, geological structure, groundwater conditions, hazardous gas conditions, and engineering geological conditions, to help construction personnel understand and predict potential adverse geological hazards, thereby formulating corresponding construction plans and safety assurance measures.

[0037] Step S102: Based on the preset construction method library, determine the corresponding construction method according to the surrounding rock type; In some embodiments, according to the "Specifications for Construction and Quality Acceptance of Highway Tunnel Engineering," the surrounding rock of a tunnel can be classified into six levels based on the rock's hardness, integrity, stability, and internal structure. Level 1 surrounding rock is the best, consisting primarily of solid, hard rock, while Level 6 is the worst, consisting primarily of loose, fragmented soil. Different construction methods are required depending on the type of surrounding rock; common methods include the two-stage method, the three-stage method, the upper and lower stage method, and the full-face method.

[0038] In one embodiment of this application, a preset construction method library is established by standardizing the construction methods corresponding to each rock type. This preset construction method library includes multiple preset mapping relationships between rock types and construction methods, and each rock type is configured with a corresponding construction method.

[0039] Step S103: Based on the monitoring data of specific geological conditions and the monitoring data of harmful gases, determine the corresponding specific construction measures; Among them, specific geological conditions such as water inrush, faults, or weak interlayers are considered. In the embodiments of this application, each specific geological condition and the situation of excessive harmful gases are configured with corresponding specific construction measures. For example, when water inrush occurs, measures such as dewatering and drainage, water-blocking curtains, and reinforced support are required. When faults or weak interlayers occur, measures such as reinforced support are required. When excessive harmful gases such as methane are detected, ventilation, fire prevention, and explosion-proof measures are required to ensure the safety of tunnel construction.

[0040] Step S104: Adjust the construction process according to specific construction measures to generate the corresponding construction process. Understandably, since each standardized construction method includes multiple procedures, such as the two-step method which includes upper step excavation, initial support, lower step excavation, and secondary lining, each procedure consists of a series of steps, which are the operations. After determining the corresponding specific construction measures, the construction method can be adjusted according to these specific construction measures, such as adding or subtracting specific procedures or operations, thereby generating the adjusted construction procedures.

[0041] Step S105: Determine the preset cycle advance of the tunnel face pile number according to the surrounding rock type and construction method; Among them, the cyclic advance refers to the distance that the tunnel face station advances after each blast or excavation during the tunnel excavation process; In some embodiments, multiple historical data of cyclic advance corresponding to the surrounding rock category and construction method can be obtained from a historical construction database. The average value of the multiple historical data of cyclic advance can be calculated, and then the average value can be used as the preset cyclic advance corresponding to the surrounding rock category.

[0042] Step S106: Determine the corresponding predicted construction operation time based on the surrounding rock type, construction procedure, and preset cycle advance. In some embodiments, based on factors affecting tunnel construction operation time such as surrounding rock type, construction sequence, and preset cycle advance, the construction operation time can be predicted by means of historical data moving average, neural network model prediction, etc., so as to determine the predicted operation time of each operation in the construction sequence.

[0043] Step S107: Receive construction organization information input by the user, combine construction procedures and predicted construction operation time, and generate a corresponding tunnel construction plan.

[0044] The construction organization information includes, for example, the division of construction work areas, the construction teams in each work area, the number of people in each position, and equipment arrangement information such as the types and quantities of construction equipment.

[0045] In the above embodiments, geological data such as the surrounding rock type, specific geological condition monitoring data, and harmful gas monitoring data of the current tunnel face pile number are obtained from advanced geological forecast data or construction design data to comprehensively understand the geological conditions of the construction area. Among them, the corresponding standard construction method can be obtained according to the surrounding rock type to ensure that the construction method matches the geological conditions; the specific construction measures can be obtained according to the specific geological condition monitoring data and harmful gas monitoring data to reduce construction risks; the construction method is adjusted according to the specific construction measures to ensure the smooth progress of the construction process; the preset cycle advance of the tunnel face pile number and the corresponding construction operation prediction time are determined according to the surrounding rock type and construction method; and the corresponding tunnel construction plan can be generated by combining the construction operation prediction time, the construction organization information input by the user, and the adjusted construction procedures.

[0046] In this application, by accurately obtaining geological data, flexibly selecting construction methods based on the actual geological conditions at the construction site, adjusting the procedures with specific construction measures, rationally determining the cycle advance and the predicted duration of construction operations, and generating a tunnel construction plan in conjunction with construction organization information, construction efficiency is improved, construction risks are reduced, and the smooth progress of tunnel construction is ensured.

[0047] It should be noted that in the process of generating the tunnel construction plan, the tunnel face chainage needs to start from the tunnel design entrance chainage. By continuously repeating the tunnel construction plan generation steps S101 to S107, the tunnel design exit chainage is reached. This is to effectively control the entire tunnel construction schedule and improve the accuracy of the construction plan.

[0048] Reference Figure 2 As a further implementation of the tunnel construction plan generation method, after generating the corresponding tunnel construction plan, the method further includes: Step S201: Obtain tunnel design parameters; Among them, tunnel design parameters can be obtained from construction design data. Tunnel design parameters can include data related to support and lining: such as the size and number of arch frames, the concrete grade and thickness of support and lining, etc. Step S202: Calculate the required quantity of raw materials based on the tunnel design parameters and generate a corresponding production plan; Based on the collected tunnel design parameters, the required quantities of major raw materials such as arch frames and concrete are calculated using relevant calculation formulas and specifications. For example, the required number of arch frames can be calculated based on the tunnel interface area and support parameters; the required quantity of concrete can be calculated based on support and lining parameters.

[0049] In some embodiments, a production plan for concrete and steel arches can be generated based on the required quantity of raw materials, combined with production capacity and supply chain conditions. This plan includes determining information such as production time, production batches, and production sequences to ensure timely supply of the required raw materials.

[0050] Step S203: Generate a corresponding demand plan based on the required quantity of raw materials and the production plan; In some embodiments, the demand plan includes determining information such as the timing, batch, and quantity of raw material procurement to ensure that production needs are met on time. Step S204: Incorporate the production plan and demand plan into the tunnel construction plan.

[0051] In the above implementation, incorporating the production plan into the construction plan helps to rationally arrange production and supply, ensuring the timely supply of the required raw materials to support the smooth progress of tunnel construction.

[0052] As one implementation of step S103, the step of determining the corresponding specific construction measures based on specific geological condition monitoring data and hazardous gas monitoring data includes: Based on monitoring data of specific geological conditions and monitoring data of harmful gases, determine whether there are specific geological conditions and / or excessive levels of harmful gases; If so, the corresponding severity level will be determined based on the pre-set construction measures database, according to the monitoring data of specific geological conditions and / or the monitoring data of harmful gases; Among them, specific geological conditions and excessive levels of harmful gases can be classified and assessed according to their severity, while the pre-set construction measures database can pre-configure specific construction measures corresponding to each severity level.

[0053] Based on the specific geological conditions and / or the severity of the hazardous gas exceedance, determine the corresponding specific construction measures.

[0054] In some embodiments, monitoring data for specific geological conditions can be categorized into three levels: minor, moderate, and severe, based on their severity. For minor cases, simpler measures can be taken, such as increased patrols and monitoring; for moderate cases, more complex measures may be required, such as enhanced support and reinforcement; and for severe cases, more stringent and comprehensive measures may be necessary, such as large-scale support and treatment.

[0055] In some embodiments, hazardous gas monitoring data can also be classified and assessed based on their concentration or the severity of exceeding the limit. For example, for hazardous gases with low concentrations or slight exceedances, conventional measures such as ventilation and fire prevention can be taken; for hazardous gases with high concentrations or severe exceedances, more stringent measures such as ventilation, explosion prevention, and personal protective equipment may be required.

[0056] In the above implementation method, specific geological conditions and excessive levels of harmful gases are classified into different severity levels, and corresponding treatment measures are determined according to the different severity levels. This facilitates the implementation of appropriate measures in a targeted manner based on specific circumstances, ensuring the safety of tunnel construction and the smooth progress of the construction plan.

[0057] Reference Figure 3 As a further implementation of the tunnel construction plan generation method, after generating the corresponding tunnel construction plan in step S107, the method further includes: Step S301: Real-time monitoring of specific geological conditions and harmful gas monitoring data at the working face pile number; The working face station number indicates the current construction location. Understanding the geological and gas conditions of the current construction area helps to promptly detect and assess changes in specific geological conditions and the extent of harmful gas exceedances.

[0058] Step S302: Determine whether there has been a change in specific geological conditions and / or the level of harmful gas exceedances; if yes, proceed to step S303; if no, do not perform any operation. Step S303: Based on the specific geological conditions and / or the level of harmful gas exceedances that have changed, determine the specific construction measures after the changes; When specific geological conditions and / or the level of harmful gas exceedances change, appropriate measures will be taken according to the changes to ensure the safety and smooth progress of construction. Step S304: Adjust the construction procedures of the tunnel construction plan according to the changed specific construction measures to regenerate the tunnel construction plan.

[0059] In the above embodiments, during the process of generating a construction plan and carrying out construction according to the plan, the specific geological conditions and the level of harmful gas exceedances at the current construction location are monitored in real time, and it is determined whether there are any changes compared to the last time the construction plan was generated. By determining the specific construction measures after the changes and adjusting the construction plan, the changes can be responded to in a timely manner, ensuring the safety and smooth progress of tunnel construction, thereby improving construction quality, reducing risks, and effectively controlling the construction progress.

[0060] As one implementation of step S106, the step of determining the corresponding predicted construction operation time based on the surrounding rock type, construction procedure, and preset cycle advance includes: Data preprocessing is performed on the surrounding rock type, construction procedure, and preset cycle advance to obtain the corresponding model input values; The model input values ​​are fed into a pre-trained construction operation duration prediction model to obtain the predicted construction operation duration.

[0061] Among them, by using the linear normalization method, the factors affecting the tunnel construction operation time, such as the surrounding rock type, construction procedure and preset cycle advance, can be mapped to values ​​between 0 and 1, thereby obtaining the corresponding model input values; In some embodiments, taking the surrounding rock category as an example: assuming the current surrounding rock category is 4a, then the current original value is 4.2; if the surrounding rock category has levels 2, 5, 4 and 6c, then the corresponding original values ​​are 2, 5, 4 and 6.4 respectively. Therefore, according to the mapping formula, the value of 4a surrounding rock mapped to the 0-1 range is (4.2-2) / (6.4-2) = 0.5. Taking the cyclic advance as an example: assuming the cyclic advance is 2m, the minimum value of all cyclic advances in the system is 0.3m, and the maximum value of all cyclic advances is 4m, then according to the mapping formula, the current 2m cyclic advance mapped to the 0-1 range is (2-0.3) / (4-0.3) = 0.45.

[0062] It should be noted that there are many factors that affect the prediction of construction operation time, including but not limited to the type of surrounding rock, construction procedures and preset cycle advance. Therefore, in actual prediction, it is necessary to adjust the influencing factors input into the prediction model according to the actual construction situation. This application embodiment does not limit this.

[0063] In the above embodiments, based on factors affecting the tunnel construction operation time such as the surrounding rock type, construction procedure, and preset cycle advance, the construction operation time can be predicted by a neural network model to determine the predicted operation time of each operation in the construction procedure.

[0064] In some embodiments, during the training process of the construction operation time prediction model, all historical input data associated with influencing factors such as surrounding rock type, construction procedure and preset cycle advance, as well as all historical output data associated with tunnel construction operation time, can be used as a data sample set. The training set and test set are then divided. By continuously training and iterating the neural network model until the preset number of iterations or the desired model performance is reached, the optimal construction operation time prediction model can be obtained.

[0065] In this embodiment of the application, taking the excavation process as an example, the excavation process includes drilling, charging, blasting, slag removal, surveying, and initial support. Through methods such as historical data moving average and neural network model prediction, it is known that the construction operation time for drilling is predicted to be 20 minutes, the construction operation time for charging is predicted to be 10 minutes, and so on. Then the system can roughly plan the construction time of the entire excavation process and the corresponding tunnel construction plan based on the number of personnel, construction equipment type and material configuration of each operation.

[0066] Reference Figure 4 As a further implementation of the tunnel construction plan generation method, the plan generation method also includes: Step S401: Receive the actual duration of the construction operation input by the user; Once each cycle of construction is completed, the actual duration of the construction operation for that cycle, as input by the user, can be received. Step S402: Correct the predicted duration of construction work based on the actual duration of the construction work; When the actual construction time exceeds or precedes the predicted time, the predicted construction time is adjusted based on the actual time to more accurately predict the construction progress and avoid construction delays or advances due to prediction deviations.

[0067] Step S403: Regenerate the tunnel construction plan based on the revised predicted construction operation duration.

[0068] In the above implementation, when the actual duration of the construction work exceeds or precedes the predicted duration at the end of each construction cycle, the predicted duration is corrected in real time and the construction plan is regenerated. By comparing the actual construction situation with the construction plan, it is convenient to adjust and optimize the construction progress and resource allocation in a timely manner, thereby improving the accuracy and operability of the construction plan.

[0069] In addition, it should be noted that during the construction process, if unexpected work stoppages occur, such as those caused by power outages or excessive gas levels, resulting in delays in the construction period, the tunnel construction plan also needs to be recalculated based on the duration of the work stoppage. By continuously adjusting and regenerating the construction plan, the construction progress can be effectively controlled and the accuracy of the construction plan can be improved.

[0070] Reference Figure 5 As a further implementation of the tunnel construction plan generation method, after generating the tunnel construction plan in step S107, step S304, or step S403, the method further includes: Step S501: Based on the tunnel construction plan, the predicted construction operation time is obtained through analysis; Step S502: Determine whether the predicted construction operation time exceeds the preset construction time threshold; if yes, proceed to step S503; if no, do not perform any operation. The preset construction duration threshold can be pre-configured and adjusted according to the actual project situation. When the predicted construction operation duration exceeds the preset construction duration threshold, it indicates that there may be a delay in the construction period.

[0071] Step S503: Send a project timeout warning signal to the user terminal.

[0072] Among them, the user terminal can be a mobile smart terminal for technicians, such as a mobile phone or tablet computer, or a computer terminal in the management room.

[0073] In the above implementation, the predicted construction operation time is compared with the preset construction time threshold to help relevant personnel understand the construction progress in a timely manner, warn of potential risks of construction delays, and take corresponding countermeasures, such as adjusting the construction plan and increasing resources, to ensure that the construction proceeds as planned and avoid delays and increased costs.

[0074] This application also discloses a tunnel construction plan generation system.

[0075] A tunnel construction plan generation system, the plan generation system comprising: The geological condition data acquisition module is used to acquire geological condition data for the current working face station; the geological condition data includes surrounding rock type, specific geological condition monitoring data, and hazardous gas monitoring data. The construction method determination module is used to determine the corresponding construction method based on the surrounding rock type, according to the preset construction method library. The specific construction measures determination module is used to determine the corresponding specific construction measures based on monitoring data of specific geological conditions and monitoring data of harmful gases. The construction procedure generation module is used to adjust the construction method according to specific construction measures and generate the corresponding construction procedure. The preset cycle advance determination module is used to determine the preset cycle advance of the face pile number based on the surrounding rock type and construction method. The construction operation prediction duration determination module is used to determine the corresponding construction operation prediction duration based on the surrounding rock type, construction procedure, and preset cycle advance. The tunnel construction plan generation module receives construction organization information input by the user, combines it with construction procedures and predicted construction operation durations, and generates a corresponding tunnel construction plan.

[0076] In the above embodiments, by accurately acquiring geological data, flexibly selecting construction methods based on the actual geological conditions at the construction site, adjusting the procedures by taking specific construction measures, rationally determining the cycle advance and the predicted construction operation time, and generating a tunnel construction plan in conjunction with construction organization information, construction efficiency is improved, construction risks are reduced, and the smooth progress of tunnel construction is ensured.

[0077] As a further implementation of the tunnel construction plan generation system, the plan generation system also includes: The monitoring module is used to monitor specific geological conditions and harmful gas data at the working face station in real time. The judgment module is used to determine whether there are changes in specific geological conditions and / or the level of harmful gas exceedances; if so, it outputs the judgment result that there are changes. The specific construction measures determination module is also used to determine the changed specific construction measures based on the specific geological conditions and / or the level of harmful gases exceeding the standard.
