Description

Technical Field

[0001] This application relates to the field of construction management technology, and in particular to a method for visual and dynamic management of tunnel construction progress. Background Technology

[0002] Among related technologies, tunnel engineering includes railway tunnels, highway tunnels, water conservancy tunnels, and subway tunnels. These tunnels are characterized by linear distribution, complex geological conditions, numerous construction procedures, and limited working space. Their construction progress management is one of the core challenges in engineering construction management.

[0003] Currently, tunnel construction progress management mainly employs three methods: traditional manual reporting, BIM-based construction progress management, and BIM / GIS integration. Traditional manual reporting involves on-site management personnel recording the progress of each construction segment using paper reports or spreadsheets, then summarizing and reporting at each level. This method suffers from low data collection efficiency, long processing times, error-proneness, delayed information transmission, information distortion, and difficulty in effectively archiving and retrospectively analyzing historical data. BIM-based construction progress management utilizes BIM technology to construct a 3D model of the tunnel project, linking the progress plan with model components to achieve visualized display and management of construction progress. However, this method lacks effective integration of the BIM model and GIS data, failing to fully reflect the impact of geospatial information such as surface elevation and geological stratification on the progress.

[0004] Existing attempts have focused on combining BIM and GIS for tunnel construction management, achieving 3D visualization through model overlay. However, current integration of BIM and GIS is still limited to model overlay and data import. There is a lack of a data mapping mechanism based on unified coding between BIM components and GIS spatial elements, and progress information cannot be automatically synchronized and transferred between the two models. At the same time, each link from deviation identification to decision execution is relatively independent, lacking a closed-loop control mechanism, resulting in a lag in management response.

[0005] Therefore, there is an urgent need for a method for visualized dynamic management and control of tunnel construction progress that can achieve automatic mapping and synchronous flow of BIM and GIS data and has closed-loop management capabilities of perception, analysis, early warning, decision-making and execution. Summary of the Invention

[0006] To address or partially address the problems existing in related technologies, this application provides a method for visually and dynamically managing tunnel construction progress, aiming to solve the technical problems of construction progress data not being able to be automatically synchronized between BIM models and GIS scenes, and the limitations in collaborative analysis and visualization.

[0007] This application provides a method for visually and dynamically managing the progress of tunnel construction, including: Construct an integrated spatial data model of BIM and GIS. The integrated spatial data model takes the construction section as the smallest management unit and establishes the mapping relationship between the construction section code, spatial coordinate range and attribute parameters of each construction section. Collect multi-source construction progress data and label the collected construction progress data according to the construction section code; Based on the mapping relationship, the labeled construction progress data is matched to the corresponding construction segment in the integrated spatial data model using the construction segment code as the index, and the progress status of the construction segment is updated synchronously and displayed on the 3D visualization platform. The actual progress of each construction section is compared with the planned progress to calculate the progress deviation rate and deviation trend. When the progress deviation rate exceeds the preset deviation threshold, a graded early warning is triggered. Based on the logical dependencies of the work processes, the impact of schedule deviations on subsequent construction sections and the overall project duration is deduced.

[0008] Optionally, an integrated spatial data model combining BIM and GIS can be constructed, including: Acquire the design BIM model of the tunnel project and the geographic information data of the construction area. The BIM model includes the design parameters, lining type and engineering quantity attribute information of each construction section, and the geographic information data includes surface elevation, geological stratification and hydrological conditions. Convert the BIM model and geographic information data to the same coordinate system for spatial registration and fusion; In the integrated model after fusion, the index relationship between BIM components and GIS spatial elements is established with the construction section code as the link.

[0009] Optionally, establish the mapping relationship between the construction segment code, spatial coordinate range, and attribute parameters for each construction segment, including: The tunnel project is divided into several construction sections along the axis according to a preset length. A unique construction section code is generated for each construction section according to a preset coding rule. The construction section code includes the project code, bid section code, construction section type code, starting chainage and ending chainage information. Determine the spatial coordinate range and attribute parameters of each construction segment in the coordinate system. The spatial coordinate range includes the three-dimensional coordinates of the starting point, ending point, and feature points on the centerline of the construction segment. The attribute parameters include design parameters, planned schedule parameters, real-time schedule parameters, geological parameters, and construction parameters. Establish a mapping table with the construction section code as the first primary key, the spatial coordinate range as the second index, and the attribute parameters as the data carrier.

[0010] Optionally, collect multi-source construction progress data, including: By deploying laser ranging equipment on key sections of the tunnel to detect the spatial position of the section in real time, and matching the construction section code of the construction section to which the section is located according to the mapping relationship, the progress status of the construction section is marked as under construction. The positioning terminal mounted on the construction machinery obtains the working position and status of the construction machinery in real time. When the position of the construction machinery enters the spatial coordinate range of a certain construction section, the machinery operation time of that construction section is recorded, and the machinery operation data is associated with the corresponding construction section code. The system receives confirmation information about completed work processes from managers via mobile terminals, and then uploads the confirmed completed construction section code, the corresponding work process name, and the completion time to the data fusion engine.

[0011] Optionally, the progress status of this construction section can be updated synchronously, including: The labeled multi-source construction progress data is transmitted to the data fusion engine; The data fusion engine receives and parses multi-source construction progress data, and matches the corresponding three-dimensional components of the construction section in the integrated BIM and GIS spatial data model according to the mapping relationship and the construction section code as the index. Real-time progress data is written into the attribute parameters of the construction section, driving the corresponding components in the BIM model and the corresponding spatial locations in the GIS scene to update their progress status synchronously.

[0012] Optionally, it can be displayed on a 3D visualization platform, including: On the 3D visualization platform, the progress status of each construction section is colored according to the preset color mark rules, generating a 3D progress status map with geological profiles superimposed, and the construction progress process is displayed in the form of timeline animation.

[0013] Optionally, trigger tiered alerts, including: The actual progress of each construction section is compared with the preset planned progress section by section to calculate the progress deviation rate and deviation trend. When the progress deviation rate exceeds the preset deviation threshold, a tiered warning is triggered. The tiered warnings include: A yellow warning is triggered when the progress deviation rate is within the first preset range. The delayed construction section is displayed in yellow highlight flashing mode on the 3D visualization platform. Orange alert: When the progress deviation rate is within the second preset range, an orange level 2 alert is triggered. The lagging construction section is displayed in orange highlight flashing mode on the 3D visualization platform, and an alert notification is pushed to the project management personnel. A red alert is triggered when the progress deviation rate falls within the third preset range. The lagging construction section is displayed in red flashing mode on the 3D visualization platform. At the same time, an alert notification is sent to project managers and construction supervisors, and a voice alarm call is automatically dialed.

[0014] Optionally, the impact of schedule deviations on subsequent construction sections and the overall project duration can be simulated, including: Extract the process logic dependencies between each construction section from the BIM model. The process logic dependencies include the preceding process, the succeeding process, and the process interval time. Starting from the current delayed construction segment, traverse the logical dependencies of the work process level by level and calculate the delay of the planned start time of each subsequent construction segment affected by the delay. Based on the delays of each subsequent construction segment, the critical path method is used to recalculate the total project duration, resulting in an updated estimated completion date. All affected construction sections and their delays are highlighted on a 3D visualization platform to generate a schedule impact analysis report.

[0015] Optional methods for visually and dynamically managing tunnel construction progress also include: Based on the impact of the projected schedule deviation on subsequent construction sections and the overall project duration, an auxiliary decision-making scheme, including resource allocation recommendations, is generated. This auxiliary decision-making scheme is then pushed to the management personnel's terminal. After confirmation, a control command is generated and directly issued to the on-site operation terminal via the communication network, forming a closed-loop control system from data perception, analysis and early warning to decision execution. Resource allocation recommendations and related decision support schemes include: Based on the schedule impact analysis report, the construction segment on the critical path that is most affected by delays was identified; To determine the reasons for the delays in the construction phase, corresponding resource allocation plans are matched from the pre-set plan library. These plans include increasing the number of construction workers, increasing the number of mechanical equipment, and extending the working time.

[0016] The technical solution provided in this application may include the following beneficial effects: A BIM and GIS integrated spatial data model is constructed with the three-element mapping relationship of construction section codes, spatial coordinate intervals, and attribute parameters as its core. Using construction section codes as an index, it realizes the synchronous and automatic matching of multi-source construction progress data to BIM components and GIS spatial elements, and the synchronous update of progress status. This enables the automatic flow and collaborative visualization of construction progress data between the two models. By comparing the actual progress of each construction section with the planned progress segment by segment to trigger hierarchical early warnings, and automatically inferring the impact of progress deviations on subsequent construction sections and the overall project duration based on the logical dependencies of work processes, it realizes the transformation from passive data collection to proactive risk prediction. Based on the inference results, a resource allocation plan is generated and issued to the on-site operation terminal in a closed loop, constructing a complete closed-loop management and control system of perception-analysis-early warning-decision-execution. This solves the problem of delayed management response caused by the lack of a closed-loop management and control mechanism, and improves the intelligence level and response efficiency of construction progress management.

While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0021] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] In some implementations, see Figure 1 A method for visually and dynamically controlling the progress of tunnel construction, comprising: S101. Construct an integrated spatial data model of BIM and GIS. The integrated spatial data model takes the construction section as the smallest management unit and establishes the mapping relationship between the construction section code, spatial coordinate range and attribute parameters of each construction section. Specifically, an integrated tunnel spatial data model combining BIM and GIS is constructed. First, the design BIM model of the tunnel project and the geographic information data of the construction area are obtained. The BIM model includes the design parameters, lining type and engineering quantity attribute information of each construction section, and the geographic information data includes surface elevation, geological stratification and hydrological conditions. Then, the BIM model and geographic information data are spatially registered and integrated in the same coordinate system, specifically including: Convert the local coordinates of the BIM model and the geographic information data into the same coordinate system; Then, the converted BIM model is spatially overlaid with GIS geographic information data to ensure that each construction segment component in the BIM model is precisely matched with its corresponding geographic spatial location in the GIS scene. In the matched BIM and GIS integrated model, a two-way index relationship is established between BIM components and GIS spatial elements, using the construction section code as the link.

[0023] Establish a ternary mapping relationship between construction section codes, spatial coordinates, and attribute parameters to form an integrated spatial data model of BIM and GIS.

[0024] The ternary mapping relationship uses the construction segment code as the unique primary key, linking the spatial coordinate range of the construction segment in three-dimensional space with all attribute parameters of the construction segment, specifically including: First, the tunnel project is divided into several construction sections along the axis according to a preset length. For each construction section, a unique construction section code is generated according to a preset coding rule. The construction section coding rule includes project code, section code, construction section type code, starting chainage and ending chainage information. Next, determine the spatial coordinate range and attribute parameters of each construction section in the coordinate system. The spatial coordinate range includes the starting point coordinates, ending point coordinates, and three-dimensional coordinates of each feature point on the centerline of the construction section. The attribute parameters include design parameters, planned progress parameters, real-time progress parameters, geological parameters, and construction parameters. Then, a mapping table is established with the construction section code as the first primary key, the spatial coordinate range as the second index, and the attribute parameters as the data carrier.

[0025] S102. Collect multi-source construction progress data and label the collected construction progress data according to the construction section code; Specifically, multi-source sensing devices are deployed inside the tunnel construction area to collect construction progress data in real time. The collected multi-source construction progress data is then labeled according to the construction section code and transmitted to the data fusion engine. The multi-source sensing devices include laser ranging devices deployed on key sections of the tunnel, Beidou positioning terminals mounted on construction machinery, and mobile terminals for use by on-site management personnel.

[0026] The collected multi-source construction progress data is labeled according to the construction section code, including: The laser ranging device detects the spatial coordinates of the cross section in real time, and automatically matches the construction section code of the construction section where the cross section is located according to the ternary mapping relationship, and marks the progress status of the construction section as under construction. The Beidou positioning terminal obtains the real-time operating location and status of construction machinery. When the location of the construction machinery enters the spatial coordinate range of a certain construction section, it automatically records the machinery operation time of that construction section and associates the machinery operation data with the corresponding construction section code. The mobile terminal receives the process completion confirmation information input by the management personnel, and uploads the confirmed completed construction section code, the corresponding process name, and the completion time to the data fusion engine.

[0027] S103. Based on the mapping relationship, the labeled construction progress data is matched to the corresponding construction segment in the integrated spatial data model using the construction segment code as the index, and the progress status of the construction segment is updated synchronously and displayed on the three-dimensional visualization platform. Specifically, when the data fusion engine receives and parses the multi-source construction progress data, it automatically matches the corresponding 3D components of the construction segment in the integrated BIM and GIS spatial data model based on the ternary mapping relationship and the construction segment code as the index. It then writes the real-time progress data into the attribute parameters of the construction segment, driving the corresponding components in the BIM model and the corresponding spatial locations in the GIS scene to update their progress status synchronously. Finally, on the 3D visualization platform, the progress status of each construction segment is colored according to the preset color mark rules, generating a 3D progress status map overlaid with geological profiles, and displaying the construction progress process in a timeline animation.

[0028] S104. Compare the actual progress of each construction section with the planned progress, calculate the progress deviation rate and deviation trend, and trigger a graded early warning when the progress deviation rate exceeds the preset deviation threshold. Specifically, the actual progress of each construction section is compared with the preset planned progress section by section to calculate the progress deviation rate and deviation trend. When the progress deviation rate exceeds the preset deviation threshold, the system automatically triggers a tiered warning. The tiered warning includes the following three warning methods: A yellow warning is triggered when the progress deviation rate is within the first preset range. The delayed construction section is displayed in yellow highlight flashing mode on the 3D visualization platform. Orange alert: When the progress deviation rate is within the second preset range, an orange level 2 alert is triggered. The lagging construction section is displayed in orange highlight flashing mode on the 3D visualization platform, and an alert notification is pushed to the mobile terminal of the project management personnel. A red alert is triggered when the progress deviation rate falls within the third preset range. The lagging construction section is displayed in red highlight flashing mode on the 3D visualization platform. At the same time, an alert notification is pushed to the mobile terminals of project managers and construction supervisors, and a voice alarm call is automatically dialed.

[0029] S105. Based on the logical dependencies of the work processes, deduce the impact of schedule deviations on subsequent construction sections and the total construction period; Specifically, based on the pre-set process logic dependencies in the BIM model, the system automatically infers the scope and degree of impact of the current construction section's delay on subsequent construction sections and the overall construction period, and generates a schedule impact analysis report. Based on the pre-defined process logic dependencies in the BIM model, the system automatically calculates the scope and degree of impact of the current construction segment's delay on subsequent construction segments and the overall project duration, including: Extract the process logic dependencies between each construction section from the BIM model. The process logic dependencies include the preceding process, the succeeding process, and the process interval time. Starting from the current delayed construction segment, we traverse step by step along the logical dependencies of the work process to calculate the delay in the planned start time of each subsequent construction segment due to the delay. Then, based on the delay of each subsequent construction section, the critical path method is used to recalculate the total project duration and obtain the updated estimated completion date. Finally, all affected construction sections and their delays are highlighted on a 3D visualization platform.

[0030] S106. Closed-loop feedback and execution of control instructions; Based on the project schedule impact analysis report, an auxiliary decision-making scheme including resource allocation recommendations is automatically generated. The auxiliary decision-making scheme is pushed to the management personnel terminal. After confirmation, a control command is generated and directly issued to the on-site operation terminal through the communication network, forming a closed-loop control from data perception, analysis and early warning to decision execution.

[0031] This includes generating auxiliary decision-making schemes that include resource allocation suggestions, such as: Based on the schedule impact analysis report, the construction segment on the critical path that is most affected by delays was identified; Then, based on the reasons for the delay in this construction section, a corresponding resource allocation plan is matched from the pre-set plan library. The resource allocation plan includes increasing the number of construction personnel, increasing the number of mechanical equipment, and extending the working time.

[0032] Corresponding to the aforementioned application function implementation method embodiments, this application also provides a tunnel construction progress visualization dynamic control system and corresponding embodiments.

[0033] A tunnel construction progress visualization and dynamic control system includes: Data acquisition layer, data fusion layer, analysis and calculation layer, visualization layer, and closed-loop feedback layer; The data acquisition layer includes multi-source sensing devices deployed in the tunnel construction area. These devices include laser ranging equipment deployed on key sections of the tunnel, Beidou positioning terminals mounted on construction machinery, and mobile terminals for use by on-site management personnel.

[0034] The data fusion layer includes a BIM-GIS mapping engine and a ternary mapping relationship database. The BIM-GIS mapping engine is used to spatially register and fuse BIM models and GIS geographic information data in the same coordinate system, and establish a ternary mapping relationship of "construction section code - spatial coordinates - attribute parameters". The data fusion layer is also used to receive and parse multi-source construction progress data collected by the data acquisition layer, automatically match the corresponding 3D components of the construction section based on the ternary mapping relationship and using the construction section code as an index, and write the real-time progress data into the attribute parameters of the construction section.

[0035] The analysis and calculation layer includes a progress analysis and early warning module. This layer compares the actual progress of each construction segment with the preset planned progress segment by segment, calculates the progress deviation rate, and triggers a tiered early warning when the deviation rate exceeds a preset deviation threshold. Simultaneously, based on the preset process logic dependencies in the BIM model, the critical path method is used to automatically deduce the scope and degree of impact of the current construction segment's delay on subsequent construction segments and the overall project duration.

[0036] The visualization layer includes a 3D visualization management platform. This platform renders the progress status of each construction section using color-coded markers according to preset color-coded rules, based on the attribute parameters updated by the data fusion layer. The platform also includes a progress replay module, a progress prediction module, and a mobile AR module. The progress replay module allows for the playback of 3D construction progress scenes at any historical time point using a timeline sliding method based on historical progress data. The progress prediction module uses machine learning algorithms to predict the trend of subsequent construction progress based on the current actual progress and planned progress. The mobile AR module allows on-site management personnel to overlay BIM design parameters and real-time progress information when scanning the tunnel wall using a mobile terminal camera.

[0037] The closed-loop feedback layer is used to automatically generate auxiliary decision-making schemes based on the project schedule impact analysis report, push the schemes to the management personnel terminal, generate control instructions after confirmation, and issue the control instructions directly to the field operation terminal through the communication network.

[0038] It achieves a complete closed-loop management and control process of data collection, analysis and early warning, and decision execution. It can automatically generate auxiliary decision-making schemes including resource allocation suggestions based on the simulation results, and directly issue the confirmed control instructions to the on-site operation terminals. It can effectively reduce the waiting and connection time between processes, optimize resource scheduling, improve control efficiency, and provide an efficient, accurate and intelligent solution for tunnel engineering construction progress management.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
