Description

Technical Field

[0001] The present invention relates to the technical field of computer-aided management of tunnel construction, and in particular to a mining tunnel construction management method based on BIM technology. Background Art

[0002] In tunnel construction, traditional technical briefing methods rely primarily on 2D design and construction drawings. This method of briefing requires high levels of spatial visualization and technical expertise from construction personnel, and can easily lead to the loss of technical details during the briefing process. Because construction drawings are mostly 2D, technicians rely on spatial visualization to construct the three-dimensional structure. This presents the problem of difficult-to-detect component conflicts in complex tunnels, which are composed of numerous structures. Furthermore, quantity statistics for tunnel projects often require manual calculations, which is not only inefficient but also difficult to ensure accuracy. Ultimately, the construction information stored in the project is primarily retained in the form of construction drawings, making detailed component construction information difficult to effectively preserve.

[0003] The existing technology has the following deficiencies in the management of tunnel construction using the mining method:

[0004] 1. Technical briefings rely on 2D drawings and lack 3D visualization support, making it difficult for construction workers to accurately understand construction details.

[0005] 2. Component conflict detection mainly relies on manual work, which is inefficient and prone to errors.

[0006] 3. Engineering quantity statistics rely on manual calculations, which are inefficient and low in accuracy.

[0007] 4. The preservation and transmission of construction information is not detailed enough, resulting in difficulties in subsequent construction and maintenance.

[0008] In view of the above problems, there is an urgent need in this field for a new mining tunnel construction management method to overcome the defects in existing construction management and improve construction efficiency and quality. Summary of the Invention

[0030] like Figure 1As shown, the mining tunnel construction management method based on BIM technology of this embodiment includes the following steps: S100, creating a 3D tunnel model based on the tunnel 2D construction drawing information, and defining the construction equipment and process flow of the mining tunnel; S200, based on BIM technology and the modeling results of step S100, using Navisworks software to generate a construction method model, showing the construction process in the form of 3D animation simulation, understanding the details of the construction nodes, and understanding the specific arrangement and size data of the relevant structures in the construction process, thereby understanding the technical explanation of the construction method and facilitating the optimization of the construction in advance. Construction process; S300, using BIM technology and combined with the collision detection tool of Navisworks software, to perform collision detection on the tunnel structure, and make timely adjustments and modifications to reduce on-site design changes and rework; S400, using BIM technology to perform 4D progress simulation of the entire tunnel construction process, and compare and analyze the difference between the planned construction workload and the actual planned workload, so as to grasp the construction progress, assist in analyzing the reasons for the delay in construction progress and make timely adjustments; S500, based on the BIM mining method tunnel model, detailed construction information is attached to the components to realize digital information management. The mining tunnel construction management method based on BIM technology, through step S100, converts the 2D construction drawing information into a 3D tunnel model, so that construction personnel can intuitively understand the construction details, reducing the dependence on the construction personnel's spatial imagination ability, thereby improving the accuracy of technical disclosure. At the same time, the intuitiveness of the 3D model also improves the efficiency of disclosure; step S200 uses Navisworks software to generate a construction method model, and simulates the construction process with 3D animation, so that the construction node details and structural arrangement and dimensional data are clear at a glance, which is convenient for construction personnel to find component conflicts in advance and optimize the construction process; step S300 uses Navisw The collision detection tool of the orks software performs collision detection on the tunnel structure, promptly discovers and adjusts conflicts in the design, reduces on-site design changes and rework, and improves construction efficiency and quality.

Step S500 adds detailed construction information to the components and realizes digital information management through BIM technology, making the storage and transmission of construction information more detailed and accurate, facilitating the subsequent construction and maintenance work.Converting 2D drawings into 3D models improves the intuitiveness and comprehensibility of information; through 3D animation simulation and 4D progress simulation of construction procedures, the construction process can be predicted and optimized in advance; using software tools for collision detection, design conflicts can be discovered and adjusted in a timely manner; attaching construction information to the model realizes the digital management of construction information, improves the efficiency of information storage and transmission, and based on the orderly progress of step-by-step processes, jointly improves the management level of mining-based tunnel construction, reduces construction risks, and improves construction efficiency and quality.

[0031] In this embodiment, step S100 specifically includes: creating a 3D tunnel model based on the tunnel's 2D construction drawing information, including parameterizing and modeling structural units such as the tunnel outline, lining, invert arch, anchor rods, steel arch frame, and steel mesh (including but not limited to these structures). In addition, to meet the requirements of the mechanized drilling and blasting method of the tunnel, BIM models are also created for slag, drill columns, construction steps, and transportation ramps (including but not limited to these structures). By converting 2D construction drawing information into a 3D tunnel model, the actual structure and dimensions of the tunnel can be reflected more accurately, reducing construction errors caused by incorrect interpretation of the drawings. At the same time, the creation of the 3D model provides an intuitive reference for construction preparation and improves the efficiency of construction preparation. Parameterized settings for each structural unit of the tunnel allow the model to be quickly adjusted according to design changes or construction needs, improving the flexibility and adaptability of the model. By creating 3D models of key structural units such as tunnel outlines, linings, and inverts, the construction team can more intuitively evaluate and optimize construction plans, such as determining the best blasting points and the layout of support structures. By accurately modeling key safety structures such as anchor bolts, steel arch frames, and steel meshes, these can be ensured during construction. The correct installation and use of the structure improves construction safety. Creating BIM models for slag, drill columns, construction steps, and transport ramps provides detailed construction guidance for mechanized drilling and blasting, helping to improve the efficiency and accuracy of mechanized construction. The 3D model provides a common communication platform for the construction team, designers, and project managers, facilitating coordination and communication on construction details and reducing misunderstandings and communication costs. The created 3D model contains all the basic data required for tunnel construction, providing essential data support for subsequent construction phases such as collision detection, schedule simulation, and information management. The precise 3D model allows for more rational planning of material usage and construction sequence, reducing material waste and construction time, and improving resource utilization efficiency. Step S100 creates a detailed 3D tunnel model, providing an accurate, intuitive, and operational reference framework for the entire tunnel construction process, thereby improving construction efficiency, safety, and quality.

[0032] In this embodiment, the modeling software adopts Autodesk's Revit series software for modeling. The specific modeling steps include: S101, importing relevant drawing information based on the plan view, longitudinal section view, and engineering geological map to determine the three-dimensional model of the tunnel location and topography and geology; S102, constructing the tunnel structure model based on the tunnel cross-section view; S103, adding structural attribute information to the corresponding tunnel model, such as the tunnel outline, lining, invert arch, anchor rod, steel arch frame and steel mesh; S104, establishing corresponding tunnel family components according to different lining types, construction methods, support types and means based on the structural design support parameters of the tunnel; S105, finally, appropriately adjusting and integrating the different types of tunnel structures established above to establish a complete three-dimensional tunnel model. Through step S101, by importing drawing information based on the plan view, longitudinal section view and engineering geological map, the location of the tunnel and the three-dimensional model of the topography and geology can be accurately determined, providing accurate geographical and geological information for subsequent tunnel design and construction; step S102 constructs the tunnel structure model based on the tunnel cross-section view, ensuring the accuracy and consistency of the tunnel design, and providing an accurate outline basis for subsequent structural design and construction; in step S103, structural attribute information is added to the tunnel model, so that the model contains not only geometric information, but also key attribute information such as material, size, and strength, providing detailed guidance for construction and material procurement; step S104 establishes tunnel family components based on the structural design support parameters of the tunnel, allowing customized design according to different lining types, construction methods, support types and means, etc., thereby improving the flexibility and adaptability of the design; step S105 adjusts and integrates different types of tunnel structures to build Establishing a complete 3D tunnel model provides the construction team with a comprehensive and detailed blueprint, facilitating coordination and management during the construction process. Through the collaborative capabilities of Revit software, the design and construction teams can work on the same model, updating and sharing information in real time, improving the efficiency of design and construction collaboration. The precise 3D model and detailed structural property information help identify design errors and potential construction issues in advance, thereby reducing rework and costs. The complete 3D tunnel model can be used for construction schedule planning and resource allocation, facilitating more precise control of construction progress and costs. With the precise model and detailed structural property information, the construction team can better understand the tunnel's safety requirements, enabling them to implement appropriate safety measures and improve construction safety. The detailed 3D model and structural property information provide basic data for the tunnel's subsequent maintenance and asset management, facilitating the development of maintenance plans and asset management. Steps S101 to S105, modeling using the Revit series of software, not only improve the accuracy and efficiency of tunnel design and construction, but also provide strong support for construction safety, schedule control, and subsequent maintenance.Optionally, a 3D tunnel model is created based on the tunnel 2D construction drawing information. When establishing the BIM model, modeling software is first selected. Commonly used software are corresponding software provided by Autodesk, Bentley, Dassault, and Nemetschek. Here, Autodesk's Revit series software is preferably used for modeling.

[0033] Optionally, when using Autodesk's Revit software to model the tunnel, the specific modeling steps are:

[0034] S101: Determine tunnel location and 3D model of topography and geology

[0035] Importing drawing information: First, you need to import the plan, longitudinal section, and engineering geology map into Revit. This can be done using the "Import CAD" function under the "Insert" tab. During the import process, you can set the scale, rotation angle, and other parameters to ensure the accuracy and consistency of the drawings.

[0036] Create a 3D terrain model: Leverage imported engineering geology maps and use Revit's modeling tools to construct a 3D terrain model. Geological data (such as a Digital Elevation Model (DEM)) can be imported into Revit, and drawing tools can be used to draw stratum boundaries and fill colors. Alternatively, Revit's wall elements can be used to represent stratum boundaries.

[0037] Integrate terrain and tunnel locations: Combine imported plan and profile views with the 3D terrain model to determine the exact location and alignment of the tunnel. Ensure the tunnel accurately matches the terrain by adjusting the model's 3D views.

[0038] S102: Constructing tunnel structure model

[0039] Import cross-section drawings: Import the cross-section drawings of the tunnel into Revit using the same method as importing other drawings.

[0040] Create tunnel profile: Based on the cross-sectional view, use Revit's parametric modeling capabilities to create the tunnel profile. Use Revit's family editor to define the tunnel's cross-sectional shape and size.

[0041] Generating a tunnel structure model: Utilizing visual programming tools like Dynamo, we perform parametric design of the tunnel structure, combining the tunnel centerline and cross-sectional profiles. Dynamo allows us to segment the road centerline and place corresponding cross-sectional profiles at each segment. Finally, we generate a complete tunnel structure model in Revit, either by placing predefined families or by directly creating solid shapes and then converting them into a Revit model.

[0042] Revit's 3D modeling capabilities enable precise simulation of tunnel structures and topographical and geological conditions, reducing design errors and improving design accuracy and reliability. Parametric modeling and automation tools, such as Dynamo, accelerate the modeling process and enhance design efficiency. The resulting 3D model serves as a common language across departments, enabling more accurate understanding and communication of project information among engineering, geology, and construction. The BIM platform enables data sharing and collaboration, improving the efficiency of engineering team collaboration. The detailed 3D model provides intuitive guidance for construction, helping construction personnel better understand the tunnel structure and construction requirements, reducing errors and rework. Furthermore, construction simulation and optimization can be performed within the model, identifying potential problems in advance and formulating more effective construction plans and management schedules. The resulting tunnel model can be used for various analyses and assessments, such as structural stability analysis and geological hazard risk assessment. These analyses provide a scientific basis for project decision-making, ensuring the safety and economic efficiency of tunnel projects.

By accurately calculating the project quantity and cost as the basis for investment control, accurate management of project costs and engineering costs can be achieved. BIM technology can provide detailed information such as construction plans, resource allocation, and progress monitoring, enabling refined management and control, and improving project management levels. The application of BIM technology has transformed technical briefings from traditional two-dimensional drawings to three-dimensional visualizations, improving the efficiency and accuracy of technical briefings and reducing construction problems caused by misunderstandings. The quality information recording function in the BIM model makes quality problems traceable and analyzable, providing data support for quality improvement. Through these effects, step S200 not only improves the quality and efficiency of construction, but also enhances the safety and compliance of the construction process, providing strong support for construction management.

[0045] In this embodiment, step S300 specifically includes: using BIM and combining the collision detection tool of Navisworks software to perform collision detection on the tunnel structure. The collision detection not only includes hard collisions between structures, but also includes functional inspections, which facilitates the improvement of errors caused by design and construction, thereby reducing the probability of rework and improving construction progress and safety quality; at the same time, automatic engineering quantity statistics using BIM technology are used to improve the efficiency and accuracy of on-site engineering quantity statistics.

BIM technology can provide real-time control and early warning of the engineering quantities used for a single floor or component, serving as a basis for material procurement and construction planning, facilitating material management and control. Parametric BIM models can prevent inaccurate statistical results caused by human error, effectively reducing costs and shortening construction periods. By reducing cost overruns, optimizing resource allocation, and improving construction efficiency, BIM 5D technology not only directly reduces project costs but also improves overall project efficiency.

In addition, in order to meet the needs of mechanized drilling and blasting methods for tunnels, BIM models such as slag, drill columns, construction steps and transportation slopes are also created; the construction equipment and process flow of the mining tunnel are defined, including designing the movement of construction equipment and creating the process flow of mining tunnel construction; the present invention simulates, monitors and analyzes the mining tunnel construction process by a BIM-based simulation method, which can realize the information management of the mining tunnel; the three-dimensional visualization of BIM technology can be used to visualize the three-dimensional excavation and support model of the tunnel. By leveraging BIM and the collision detection tool of Navisworks software, collision detection can be performed on tunnel structures, reducing design changes and rework. BIM technology can be used to simulate the entire tunnel construction process in 4D, compare and analyze the difference between the planned construction workload and the actual planned workload, assist in analyzing the reasons for the delay in construction progress from the perspective of overall construction, realize 4D construction progress management, and improve the efficiency of construction progress management. At the same time, BIM technology can be used for automatic engineering quantity statistics to improve the efficiency and accuracy of on-site engineering quantity statistics. The present invention expands the application field of BIM technology, effectively improves the safety management capability and level in the construction of mining-based tunnels, and provides a new technical means to ensure the safety of life and property during the construction of mining-based tunnels.

[0051] like Figure 1 As shown, the mining tunnel construction management method of the present invention which introduces BIM technology includes the following steps:

[0052] Step S1: Create a 3D tunnel model based on the tunnel's 2D construction drawings. This involves parameterizing and modeling structural elements such as the tunnel outline, lining, invert, anchors, steel arches, and steel mesh. Furthermore, to meet the requirements of the mechanized drill-and-blast method for the tunnel, BIM models are also created for elements such as slag, drill columns, construction steps, and transport ramps.

[0053] In step S1, a 3D tunnel model is created based on the tunnel 2D construction drawing information. When establishing the BIM model, the modeling software is first selected. The more commonly used software are the corresponding software provided by Autodesk, Bentley, Dassault, and Nemetschek. Here, Autodesk's Revit series software is preferred for modeling. The specific modeling steps are as follows: Figure 2 As shown:

[0054] S101 imports relevant drawing information based on the plan view, longitudinal section view, and engineering geological map to determine the location of the tunnel and a three-dimensional model of the topography and geology;

[0055] S102 constructs a tunnel structure model based on the tunnel cross-section diagram;

[0056] S103 adds structural attribute information to the corresponding tunnel model, such as tunnel outline, lining, invert arch, anchor rod, steel arch frame and steel mesh;

[0057] S104 establishes corresponding tunnel family components based on the tunnel's structural design support parameters and different lining types, construction methods, support types and means;

[0058] Finally, S105 appropriately adjusts and integrates the different types of tunnel structures established above to establish a complete three-dimensional tunnel model.

[0059] Step S2, defining the construction equipment and process flow of the mining method tunnel, including designing the construction equipment actions and creating the mining method tunnel construction process flow;

[0060] In step S2, the construction equipment movements are designed. Specifically, the multi-functional drilling rig, rock drilling rig, loader, transport vehicle, wet spraying machine and arch trolley are first established, and then the equipment movement relationship and work schedule are defined, such as the loader bucket rotation movement relationship, loading and unloading of slag and other schedules.

[0061] In step S2, a mining tunnel construction process is created. Specifically, the construction model is first allocated according to the equipment resources required for the construction process, and then the attributes such as equipment time consumption and work sequence are defined. Finally, the construction machinery and staff are allocated to the corresponding construction process.

[0062] Step S3: Based on BIM technology and the above-mentioned modeling results, Autodesk's Navisworks software is used to generate construction method models such as the step method, CRD, and double-sidewall pilot tunnel method. The complex construction process is displayed in the form of 3D animation simulation. The model is used to understand the details of the construction nodes, the specific arrangement of the relevant structures, and the dimensional data of the components, which facilitates the technical explanation of the construction method and the optimization of the construction process in advance.

[0063] In step S3, specifically based on the above modeling results, as Figure 3 Add construction-related laws and regulations, construction specifications, contract documents, construction organization design, machinery and equipment, temporary facilities and other data information to the BIM model to form a complete construction phase model.

[0064] In step S3, a new visual briefing model for mining-based tunnel construction was created based on BIM technology. BIM technology was used to visualize the technical briefing's design specifications, process flow, construction process simulation, safety and civilized construction precautions, and quality control measures. Visual, systematic training for on-site workers, delivered via PC and mobile devices, effectively addressed issues such as low literacy, weak cognitive abilities, and difficulty understanding written briefings among on-site construction personnel. This systematic training improved workers' construction skills, their ability to identify and address safety risks, and their awareness of civilized and environmental protection, accelerating the transition from traditional workers to industrialized and information-based workers.

[0065] Step S4: Using BIM and the collision detection tool of Navisworks software, collision detection can be performed on the tunnel structure to reduce design changes and rework;

[0066] In step S4, BIM is used in combination with the collision detection tool of Navisworks software to perform collision detection on the tunnel structure. The specific collision detection includes not only hard collisions between structures but also reserved dimensions between structures. This function facilitates the correction of errors caused by design and construction, reduces the probability of rework, and improves construction progress and safety quality.

[0067] Step S5: Automatic engineering quantity statistics based on BIM technology can be used to improve the efficiency and accuracy of on-site engineering quantity statistics;

[0068] In step S5, automatic quantity calculation of engineering works is performed using BIM technology. Specifically, based on the three-dimensional model of the mining tunnel created in the early stage, a detailed quantity list of the corresponding components is automatically generated using Revit. The detailed list provides information such as the material, area, and volume of the components. The material consumption and cost of the tunnel construction can then be accurately and quickly calculated through the detailed list, so that planning can be done in advance, thereby effectively improving the economic benefits of the project.

[0069] Step S6: Using BIM technology, a 4D progress simulation can be performed on the entire tunnel construction process. The difference between the planned construction workload and the actual planned workload can be compared and analyzed to facilitate the grasp of the construction progress and timely adjustment of the construction plan. Based on the BIM model, repeated progress simulation of the tunnel construction process can be achieved to assist in analyzing the reasons for the delay in tunnel construction progress from the perspective of overall construction. The tunnel construction progress picture is displayed in the form of a 3D roaming tour, realizing 4D construction progress management and improving construction progress management efficiency.

[0070] In step S6, according to Figure 4The BIM-based mining tunnel construction plan preparation process, with the joint participation of construction technicians and safety management personnel, uses virtual construction technology to prepare and modify the construction plan; in the preparation process, BIM technology can be fully utilized for 4D construction progress simulation, and the construction progress plan can be continuously modified and improved.

[0071] like Figure 4 As shown, a construction management flowchart based on BIM (Building Information Modeling) technology is displayed. The flowchart describes the operation process of the construction BIM data platform, and how to optimize the construction model and manage the construction progress through this platform. Specifically including: the construction BIM data platform, which is the core of the entire construction management process, used to store and manage all construction-related BIM data; BIM construction model, which extracts or creates the construction model from the data platform, is the basis of the construction process; model lightweighting, which optimizes the BIM model to reduce the complexity and data volume of the model for efficient use in different devices and software; construction component family library, which calls or creates a new construction component family library, which is a collection of various components in the construction model and can be reused; refine the construction progress, which refines the construction progress information according to the construction plan to ensure that each stage of construction can be completed on time; safety management information, which integrates safety management information during the construction process to ensure construction safety;

[0072] Feasibility of the plan: On the construction BIM data platform, the construction plan is evaluated to determine whether it is feasible. If the plan is not feasible, it is necessary to return to the steps of lightweighting the model, calling or creating a new one, refining the construction progress, and the safety requirements of the plan for adjustment and improvement. If the plan is feasible, construction will continue. Adjustment and improvement: During the construction process, the construction model and progress are adjusted and improved according to the actual situation to cope with possible changes. The construction management process based on BIM (Building Information Modeling) technology emphasizes the application of BIM technology in construction management. Through the integration and management of the data platform, the construction model is optimized, the construction progress is refined, and the construction safety management is managed, ultimately ensuring the feasibility of the construction plan and the smooth progress of the construction process.

[0073] Step S7: Finally, detailed construction information is added to the components based on the BIM mining tunnel model to achieve digital information management.

[0074] In step S7, detailed construction information is added to the components based on the BIM mining tunnel model, enabling digital information management. The core of BIM technology is a data repository that contains 3D models. This allows for detailed recording of all data and information during the project construction process. This has transformed traditional project management methods, evolving from paper-based archiving to electronic archiving. This shifts management from linear to three-dimensional, evolving from drawing management to the management of core model information.

[0075] The present invention introduces a mining tunnel construction management method using BIM technology. Based on construction drawings and project-related information, a three-dimensional tunnel model is established, and the construction equipment and process flow of the mining tunnel are defined. Based on BIM technology, the following are achieved: (1) visual technical briefing work, (2) collision detection of tunnel structure, (3) 4D progress simulation of the construction process, and (4) rapid and accurate statistics of engineering quantities.
