Technical Field

[0001] The present invention relates to the technical field of tunnel construction information management, and in particular to a shield tunnel construction information visualization management method based on model knowledge information expression. Background Art

[0002] The construction of shield tunnel is a fully mechanized construction method in the dark excavation method. It is a mechanized construction method that uses the shield shell and segments to support the surrounding rock to prevent collapse and form a tunnel structure. In the conventional tunnel construction process, it is often necessary to ensure a good construction environment, both to ensure stable air pressure and to ensure the stability of the working surface. This requires the relevant information data of each component project in the tunnel as the basis, and to go through coordination and communication between multiple departments to achieve a smooth shield tunnel construction process.

[0003] At present, the research on shield tunnel construction management is still in its preliminary stage. There are often certain problems with the management methods in most scenarios. The parties involved in collaborative management cannot conveniently enter, modify and visualize information anytime and anywhere, which reduces the decision-making level of engineering management. The standardization and systematization of related coding also needs to be improved. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides a method for visualizing shield tunnel construction information based on model knowledge information expression, which solves the problem of messy information of various components in the shield tunnel construction process and can collaboratively display shield tunnel construction information.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a method for visual management of shield tunnel construction information based on model knowledge information expression, which specifically includes the following steps:

[0006] Step 1: Classify shield tunnel construction information into equipment layer, pipeline layer and segment layer, and encode them respectively;

[0007] Step 2: The coded shield tunnel construction information is expressed using model knowledge, a model knowledge information system is established according to the relationship between various shield tunnel construction information, and the system is stored in a shield tunnel database;

[0008] Step 3: Create a form in the shield tunnel database, capture the corresponding tunnel construction information from the model knowledge information system according to the form fields, visualize the tunnel construction information through the form, and collaboratively manage the visualized form.

[0009] Furthermore, the model knowledge information system established in step 2 includes: establishing a model knowledge information system for each layer in the equipment layer, pipeline layer, and pipe layer, and establishing a model knowledge information system between any two layers in the equipment layer, pipeline layer, and pipe layer.

[0010] Furthermore, the process of encoding the device layer in step 1 is as follows: the first bit of the device layer encoding is represented by S, the second bit is used to distinguish the system level of the device, the third bit is used to express the type of the device, and the fourth and fifth bits are used to represent the specific type of the device.

[0011] Furthermore, the model knowledge information system of the equipment layer includes: entity information consisting of geometric information and physical properties of the equipment, and dynamic information consisting of the installation location and practical status of the equipment.

[0012] Furthermore, the process of encoding the pipeline layer in step 1 is as follows: the first digit of the pipeline layer encoding is represented by X, and the second and third digits are used to represent the specific type of the pipeline.

[0013] Furthermore, the model knowledge information system of the pipeline layer includes: the geometric shape of the pipeline, the material of the pipeline, the functional positioning of the pipeline in the tunnel and the connection method.

[0014] Furthermore, the process of encoding the pipe segment layer in step 1 is as follows: the first digit of the encoding of the pipe segment layer is represented by G, the second and third digits are used to represent the material type of the pipe segment, the fourth digit is used to distinguish the shape of the pipe segment, and the fifth digit is used to represent the basic composition of the pipe segment.

[0015] Furthermore, the model knowledge information system of the segment layer includes: entity information consisting of geometric information and physical properties of the segments and spatial constraints between the segments.

[0016] Furthermore, the entity information of each segment in the segment layer is expressed by creating a three-dimensional model of each segment through BIM software, the geometric information of the segment is displayed through the three-dimensional model, and the physical properties and coding of the segment are edited through the property editing function of the BIM software.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the present invention classifies and encodes the shield tunnel construction information based on the visualization management method of the shield tunnel construction information expressed by the model knowledge information, and solves the problem of information clutter in the shield tunnel construction process by encoding and standardizing the shield tunnel construction information, thereby ensuring the accuracy and retrieval efficiency of the shield tunnel construction information and enhancing the traceability of the tunnel construction information during the construction process; at the same time, the present invention uses the model knowledge expression to establish a model knowledge information system according to the relationship between the various construction information of the shield tunnel. The model knowledge information system improves the efficiency of information integration and the coordination of the construction process by clarifying the logical relationship between the shield tunnel construction information, and provides a structured reference framework for the construction team, which is helpful to optimize resource allocation, reduce construction risks, and improve construction quality and safety standards; and the established model knowledge information system can be imported into the platform database to realize the collaborative design of three-dimensional visualization scenes, realize the coordinated management of the model knowledge information system, and further gain insight into the automatic association information in the information network by retrieving the specified components in the database, and display the shield tunnel construction information in a graphical manner, which is convenient for tracking analysis and collaborative modification.

[0022] The technical solution of the present invention is further explained below in conjunction with the accompanying drawings.

[0023] like Figure 1 The flowchart of the method for visualizing the construction information of a shield tunnel based on model knowledge information expression of the present invention is as follows:

[0024] Step 1: Classify the shield tunnel construction information into equipment layer, pipeline layer and segment layer, ensuring the clear structure of the shield tunnel construction information, facilitating accurate management and operation by professionals, and then encode them separately to achieve standardized management of shield tunnel information, which not only simplifies data storage and access, but also reduces human errors, improves data consistency, operability and retrieval efficiency, and promotes cross-domain collaboration and information sharing, providing accurate data support for decision-making. Specifically,

[0025] The equipment layer is encoded to identify the equipment used in the shield tunnel construction process. The specific encoding process is shown in Table 1-3. The first digit of the equipment layer encoding is represented by S; the second digit is used to distinguish the system level of the equipment, including: shield construction supporting equipment, rail transportation system and other supporting equipment, represented by 0, 1, and 2 respectively; the third digit is used to express the type of equipment, and the fourth and fifth digits are used to indicate the specific type of equipment.

[0031]

[0032]

[0033] The pipeline layer is encoded to identify pipelines during shield tunnel construction. The specific encoding process is as follows: the first digit of the pipeline layer encoding is represented by X, and the second and third digits are used to represent the specific type of pipeline, such as: high-pressure air duct 01, high-pressure water pipe 02, ventilation pipe 03, power line 04, lighting line 05.

[0034] The segment layer is encoded to identify the segments in the shield tunnel construction process. The specific encoding process is shown in Table 4. The first digit of the segment layer encoding is represented by G, and the second and third digits are used to indicate the material type of the segment, such as reinforced concrete segment 01, cast iron segment 02, steel segment 03, composite segment 04, etc.; the fourth digit is used to distinguish the shape of the segment, and the fifth digit is used to indicate the basic composition of the segment.

[0036]

[0037] Step 2. Express the encoded shield tunnel construction information using model knowledge, establish a model knowledge information system according to the relationship between the various shield tunnel construction information, and save it in the shield tunnel database. Model knowledge expression is a structured method for organizing and representing complex systems or objects. It decomposes shield tunnel construction information into multiple levels so that each part can be clearly and systematically represented and managed. The coding system provides accurate identification and description for the model knowledge information system, ensuring that the data and information used at different levels and different links are consistent and accurate, thereby improving the efficiency of information management. The model knowledge information system established in the present invention includes: establishing a model knowledge information system for each layer in the equipment layer, pipeline layer, and segment layer, and establishing a model knowledge information system between any two layers in the equipment layer, pipeline layer, and segment layer. Specifically, Figure 2 In the multi-level structure of shield tunnel construction information, the equipment layer, pipeline layer and segment layer are all regarded as its subsets, and the component layer is further subdivided based on these subsets. This hierarchical structure tree reflects the relationship and hierarchy between different components in shield tunnel construction information; any two layers in the equipment layer, pipeline layer and segment layer are connected by dotted lines, reflecting the complex functional, spatial and information relationship between the various components. These connections are not just simple visual expressions, but the actual mutual dependence and collaboration of the above components during the design, construction and operation process. For example, the equipment layer may be connected to the segment layer by a dotted line, indicating the direct connection between the equipment and the segment during installation and transportation; the pipeline layer is connected to the equipment layer and the segment layer by dotted lines, reflecting its functional support and data exchange requirements in the tunnel system. This structured connection method ensures the reasonable layout and effective coordination of various components in three-dimensional space, and provides a clear information exchange channel for the management and maintenance of tunnel projects.

[0038] The model knowledge information system of the equipment layer includes: entity information composed of the geometric information and physical properties of the equipment, and dynamic information composed of the installation location and practical status of the equipment. The geometric information of the equipment includes the shape and size of the equipment, and the physical properties of the equipment include the power and energy consumption of the equipment. Here, the rail vertical transportation lifting gantry equipment is taken as an example, and its entity information is expressed as shown in Table 5. Therefore, the geometric size, shape, power, energy consumption, installation and use status information of the equipment are recorded in detail in the model knowledge information system of the equipment layer. It can be seen that the model knowledge information system of the equipment provides comprehensive and accurate information, which not only ensures the integrity and traceability of the information, but also improves the equipment use efficiency and construction safety. At the same time, it provides strong data support for decision-making, risk management and cost control, optimizes the construction process and improves the overall construction efficiency.

[0040]

[0041] The model knowledge information system of the pipeline layer provides a solid data foundation for optimizing pipeline layout and maintenance plan by systematically recording the geometric shape, material, functional positioning and connection method of the pipeline. For example, for the high-pressure air duct, its knowledge information expression is shown in Table 6. The model knowledge information system records the length, diameter, material and strength grade of the pipeline in detail. This key information helps to evaluate the performance and applicability of the pipeline and ensure that it plays its expected function in the tunnel system. Through this information expression, the installation location of the pipeline can be accurately planned, maintenance work can be predicted and scheduled, and the compatibility and safety of the pipeline can be considered in the design stage, so as to build an efficient and reliable tunnel pipeline.

[0042] Table 6 Information expression of high pressure air duct

[0043]

[0044] The model knowledge information system of the segment layer includes: entity information composed of the geometric information and physical properties of the segment and the spatial constraints between the segments. Specifically, taking the reinforced concrete hexagonal segment-standard block coded as G0131 as an example, the geometric information includes specific parameters such as the segment ring outer diameter, wedge amount, thickness, etc. These geometric information are closely related to the physical property information, because the geometric shape determines the physical performance of the segment in the structure, such as bearing capacity and installation accuracy. Since the physical property information of the segment is difficult to express simply by simple numerical values, BIM technology can visualize these complex information in three dimensions in BIM software. The present invention uses BIM technology to express the entity information of each segment in the segment layer by creating a three-dimensional model of each segment through BIM software, displaying the geometric information of the segment through the three-dimensional model, editing the physical properties and coding of the segment through the attribute editing function of the BIM software, and closely linking the detailed geometric information of the segment such as the ring outer diameter, wedge amount, thickness, and physical properties such as compressive strength and impermeability grade with specific codes, thereby realizing the digitization and three-dimensional visualization of the segment information. Taking the reinforced concrete hexagonal segment-standard block coded as G0131 as an example, its information table is shown in Table 7. The entity information is as follows: Figure 3 Through the above technical means, a comprehensive, accurate and intuitive expression of the geometric information and physical properties of shield tunnel segments is achieved.

[0045] Table 7G0131 Reinforced concrete hexagonal segment-standard block entity information expression

[0046]

[0047] The spatial constraint relationship is a correct description of the relative position relationship between the basic components of the segment. Because the constraint method of connecting the basic components between the segments is based on bolt connection, the constrained plane of the segment constraint object is divided into rigid constraint and flexible constraint according to the different bolt connections between different segment blocks and rings. Combined with the coding system, a constraint information library between each other is created, see Table 8.

[0049]

[0050] Step 3. Create a form in the shield tunnel database, and grab the corresponding tunnel construction information from the model knowledge information system according to the form fields. You can also modify the data type of the tunnel construction information in the form fields to ensure the accuracy and consistency of the data. For example, set the data type of the entity model field to a hyperlink. The hyperlink type field can be associated with the established parametric modeling model file, so that users can directly access and view the absolute path of the model through the form, and realize the visualization of tunnel construction information. At the same time, set the component code as the primary key to ensure that each component has a unique identifier. The primary key plays a key role in the shield tunnel database and is used to establish the relationship between tables. For the entry of data information, for fields with a text data type, enter the corresponding data according to the assembly information model. For the hyperlink type entity model field, right-click the field cell and select the hyperlink option to link to the parametric model file. You can intuitively view and manage the three-dimensional model of each component, such as Figure 4 shown.

[0051] In order to achieve coordinated operation in actual scenarios, the collaborative management database adds component energy consumption information, quality information, and scheduling information to the database. The purpose of building a collaborative management database platform is to integrate energy consumption information, quality information, and scheduling information into a comprehensive database to achieve coordinated operation in actual scenarios, so as to improve the efficiency and accuracy of project execution and achieve comprehensive collaborative management of components. In the collaborative management database, energy consumption information includes energy data consumed by components or equipment during operation, such as electricity and fuel consumption, through which energy management and energy saving optimization can be carried out. Quality information covers the quality indicators of components or equipment, including material quality and manufacturing process control data, which is crucial to ensuring project quality and safety. Scheduling information involves the time arrangement and plan management of components or equipment in project execution, including construction progress, task allocation, and work cycle. Effective scheduling management helps optimize resource utilization and ensure the smooth progress of the project.

[0052] The innovation of building a collaborative management database platform is specifically reflected in the integration and sharing of multi-level information, dynamic information update and real-time management, automated conflict detection and optimization, and intelligent decision support. The platform integrates various types of information such as energy consumption, quality, and scheduling into one platform to achieve comprehensive information sharing and management, making project management more comprehensive and efficient. By receiving and integrating data from different disciplines and updating it to the collaborative management platform in real time, the data is kept up to date, facilitating real-time management and decision-making. The platform can also automatically detect and resolve conflicts between different processes and resources, improving the coordination and efficiency of the construction process. The integrated various data analysis and query tools support intelligent decision-making, for example, optimizing energy management strategies through energy consumption data analysis, and early warning and solving quality problems through quality data analysis.

[0053] The newly added energy consumption, quality and scheduling data complement and expand the information in the existing database, enriching the functions and application scope of the database. By establishing relational tables and integrating information, the relevance between the newly added data and the existing data is ensured to form a unified collaborative management platform. For example, energy consumption data can be associated with the operating status and location information of the equipment, making management and analysis more comprehensive and in-depth. This complementarity and integration of information enhances the comprehensive management capabilities of the database and supports more efficient decision-making and construction process management.

[0054] Specific methods for adding information to the database include data import and format conversion, automated data collection and entry, and manual review and data verification. The newly added information is mainly imported into the database through standardized formats such as .csv or .xlsx files to ensure data consistency and integrity. Secondly, sensors and IoT technology can also be used to realize the automated collection of equipment energy consumption, quality, and scheduling data, and enter them into the database in real time to ensure the real-time and accuracy of the data. Finally, through regular manual review and data verification, the imported and collected data is verified to ensure its accuracy, such as regularly checking energy consumption data to ensure that it is consistent with the actual situation. These methods together ensure that the newly added information is smoothly integrated into the database, providing reliable data support for collaborative management.

[0055] The relationship page contains the basic information base of the shield tunnel, including the entity information base, equipment information base and pipeline information base. Each information base contains the corresponding attribute information, and the information base contains the editing and collaboration of collaborative information. Taking the number of shield tunnel equipment information as an example, the editing of collaborative information forms the shield tunnel equipment information base in the form of a database, saves the result as an .mdb file, and forms an information association with the shield tunnel. When receiving data information from other disciplines, add it to the original collaborative management database to become a new form of the database, and create relationships between the forms in the relationship interface to achieve the collaboration of other levels of component information, such as the shield tunnel pipeline information base, the shield tunnel entity information base, etc.

[0056] Taking actual operation as an example of the expression of collaborative management information, after adding quantity information, location information, and work status information to the collaborative management database and establishing relationships between tables, the collaboration between all data has been realized. At this time, using the table generation tool in the access database query tool, all quantity information, location information, work status information, and scheduling information related to a certain equipment can be reflected in one table.

[0057] Create a new query design, select Generate Table, and edit the required integrated information fields below. Due to the rules for storing information in database tables, all information will be concentrated in one tuple, that is, one row. This may be less intuitive. However, it will not affect the computer's call for data. Run the query to obtain the data results of the collaborative management database integration, and achieve the goal of collaborative management information expression.

[0058] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
