Description

Technical Field

[0001] This invention relates to the field of engineering digitization and information technology, specifically to the application method of BIM model engineering management for water conveyance tunnels. Background Technology

[0002] Currently, engineering digitization and information technology have developed rapidly and been widely applied in my country. However, there is still room for improvement in the breadth and depth of their application, especially in specific engineering fields. Building Information Modeling (BIM) technology, as an important representative of digital transformation, is widely required in new large-scale engineering projects in order to improve the construction quality and management level of these projects.

[0003] While BIM technology has demonstrated relatively deep application in fields such as building construction and municipal engineering, and has gained widespread industry recognition in the design, construction, and even operation and maintenance phases, its application in water conservancy projects is relatively less widespread and in-depth. In particular, when integrating BIM technology with the actual business management systems during the engineering construction process, it often faces the dilemma of data silos and insufficient application depth, failing to fully realize BIM's potential as an information integration and collaboration platform.

[0004] As a core component of water conservancy and water diversion projects, the effectiveness of the construction and management of water conveyance tunnels is crucial to the success of the entire project. However, in current practice, the application of BIM for water conveyance tunnels often fails to effectively integrate with specific business management needs. This is reflected in the fact that the breakdown of the BIM model does not fully consider the needs of management dimensions and data interaction, resulting in a mismatch between the model granularity and management units. Simultaneously, the massive amounts of business data generated during the management process lack systematic classification standards and unified coding rules, making it difficult to establish a clear and accurate correspondence with the component information in the BIM model. This situation creates a significant barrier to the correlation between the BIM model and actual management operations, hindering the effective implementation of refined BIM-based management and digital applications. Therefore, there is an urgent need for an application method that can systematically integrate the BIM model of water conveyance tunnels with engineering management operations to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] To address the shortcomings of existing BIM technology applications in water conveyance tunnels, such as data fragmentation, insufficient integration with engineering construction business management systems, unclear classification of management business data, lack of unified coding rules, ambiguous BIM model splitting rules and modeling accuracy, and unclear model component coding data, which result in insufficient correlation between business data and the BIM model and hinder the full realization of the value of BIM technology, this invention provides a method for applying BIM model engineering management business in water conveyance tunnels. This method aims to systematically organize and standardize the coding of management business and engineering structures, deeply integrate them with the BIM model, and ultimately realize the digital application of various management businesses in the digital construction management system, thereby improving the precision, level, and efficiency of engineering construction management.

[0006] To achieve the above objectives, this invention provides an application method for BIM model engineering management of water conveyance tunnels.

[0007] This method first involves sorting out management business to determine the content of management business modules, and simultaneously sorting out the division of engineering units to determine the hierarchical structure of engineering units such as unit projects, sub-projects, unit projects, and processes.

[0008] Next, the relevant data information involved in each management business module identified above is meticulously classified and encoded according to unified coding rules to form structured business data coding results. Simultaneously, the hierarchical structure data of the identified engineering units is standardized and coded using a hierarchical structure coding method, thereby forming engineering division coding results. These business data coding results and engineering division coding results together constitute the core of the data standardization of this invention.

[0009] Subsequently, based on the modeling methods guided by the aforementioned business data coding results and engineering division coding results, a BIM model of the water conveyance tunnel was created using mainstream BIM modeling software. The key is that, based on the already created BIM model of the water conveyance tunnel, the components in the model are innovatively assigned the previously formed business data coding results and engineering division coding results. This allows the BIM model components to carry standardized coding information, transforming them into BIM data that can be recognized and associated by the system.

[0010] Furthermore, all business data generated based on the aforementioned business data coding results, along with BIM data carrying coding information, are uniformly input into a digital construction management system. Within this digital construction management system, the aforementioned business data coding results, which are assigned to BIM model components and are also reflected in the business data, and the project division coding results are used as common coding identifiers to achieve effective association and integration between business data and BIM data carrying coding information, forming a holographic data network with logical relationships.

[0011] Ultimately, within the digital construction management system, based on the close connection established between BIM data and business data through common coding identification, various digital applications of engineering management business are carried out, such as investment analysis and decision-making, progress simulation and analysis, quality tracking and traceability, and safety visualization control, thereby fully leveraging the value of BIM technology in water conveyance tunnel engineering management.

[0012] In one specific embodiment of the present invention, the sorted management business modules may include one or more of the following: investment management module, progress management module, quality management module, safety management module, and materials management module, to adapt to the comprehensive needs of project management.

[0013] In another specific embodiment of the present invention, the created water conveyance tunnel BIM model may specifically include models of different construction stages or structural parts, such as the side arch excavation BIM model, the bottom slab excavation BIM model, the shotcrete BIM model, the anchor bolt BIM model, the side arch BIM model, and the bottom slab BIM model, depending on business management needs and the accuracy of engineering unit division.

[0014] Preferably, when creating a BIM model of a water conveyance tunnel, the tunnel can be segmented along its axis at predetermined lengths (e.g., 1 meter) to form refined BIM model components. The step of assigning the business data coding results and the engineering division coding results to the BIM model components specifically involves assigning at least one code from the engineering division coding results to each segment of the BIM model component, such as a unit project code, starting station number, and ending station number, thereby achieving precise mapping of the project location and scope.

[0015] To ensure the effective implementation of this method, the digital building management system has a BIM model data parsing function to read and understand the input BIM model; a BIM model output management function to store and manage BIM data; and a BIM model visualization function to present the model and its associated business information intuitively.

[0016] The present invention may also include continuously updating and maintaining the input business data and the BIM data carrying the coding information in the digital construction management system to ensure the timeliness, accuracy and completeness of the data during the project implementation process, so as to support dynamic management decisions.

[0017] This invention, through the aforementioned technical solution, innovatively proposes a dual coding system for business data and engineering division, starting from management business needs. This coding system is then deeply bound to BIM model components. A digital construction management system is used as an integration platform, breaking down the barriers between business data and the BIM model through unified coding identifiers. This data association method, with coding as the core link, is key to achieving deep digital application in water conveyance tunnel engineering management, ensuring that the BIM model is no longer an isolated geometric display, but truly becomes the information core that carries and drives management operations.

[0018] This invention provides an application method for BIM model engineering management of water conveyance tunnels. It has the following beneficial effects:

[0019] 1. This invention first identifies management business modules by sorting out management business processes and then identifies engineering unit hierarchical structures by sorting out engineering unit divisions. Subsequently, a unified coding rule and hierarchical structure coding method are used to form business data coding results and engineering division coding results for these sorted business data information and engineering unit hierarchical data respectively. This enables the complex management information and engineering structure information in water conveyance tunnel projects to obtain systematic classification and standardized digital expression, laying a clear and orderly technical foundation for subsequent data integration and application.

[0020] 2. After creating the BIM model of the water conveyance tunnel, this invention innovatively assigns the aforementioned business data coding results and engineering division coding results to the components of the BIM model. This transforms the BIM model from merely a three-dimensional geometric display into BIM data carrying rich, standardized business and structural attributes. This technical processing method significantly enhances the BIM model's ability as an information carrier, enabling it to participate more directly in the specific business processes of engineering management.

[0021] 3. This invention inputs business data generated based on business data coding results and BIM data carrying coding information into the digital construction management system together. It uses the business data coding results and project division coding results as a common coding identifier, achieving precise association between business data and BIM model components within the system. This unified coding-based technical association mechanism effectively solves the problem of fragmentation between BIM data and various management business data in the traditional model, constructing a unified data environment.

[0022] 4. By establishing a close link between business data and BIM data carrying coded information through a common coding identifier within the digital construction management system, this method can support various specific digital applications for business management, such as digital management of investment, progress, quality, and safety. This application method based on coding association allows management instructions and feedback to be directly linked to specific objects in the BIM model, improving the pertinence and accuracy of management decisions.

[0023] 5. The BIM model decomposition proposed in this invention is based on business data coding and engineering division coding. For example, the water conveyance tunnel is divided into BIM model components along its axis at predetermined lengths and assigned corresponding engineering division codes. This ensures that the precision of the BIM model can meet the needs of different management businesses and enables effective and accurate correspondence between management business data and BIM data. This enhances the depth and breadth of BIM technology application in water conveyance tunnel engineering management and provides solid data support for subsequent implementation of more advanced engineering digital analysis and control.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the application method of the BIM model engineering management business for water conveyance tunnels provided by this invention will be further described in detail below with reference to the accompanying drawings and one or more specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0032] Please see the appendix Figure 1 -Appendix Figure 7 This invention discloses a method for applying a BIM model of a water conveyance tunnel in conjunction with engineering management procedures. This method is implemented by integrating BIM technology into a digital construction and management system, which serves as the project's business management system. The method involves classifying and encoding management procedures and engineering information, and then combining these codes with the BIM model and inputting them into the digital construction and management system to implement digital management procedures.

[0033] Reference Figure 1 The flowchart shown illustrates the application method of the present invention, which combines a BIM model of a water conveyance tunnel with engineering management procedures. This application method may include the following steps:

[0034] S1. Conduct a review of management procedures and divide engineering units;

[0035] S2. Classify and encode the data for management operations and engineering units;

[0036] S3. Create a BIM model based on the classified and coded data, and encode and connect the BIM model components;

[0037] S4. Input the sorted business data and BIM data into the digital building management system;

[0038] S5. Implement BIM-based digital applications for business management in the construction management system.

[0039] In one specific embodiment of the present invention, step S1 involves conducting a management business review and engineering unit division, which is a fundamental preliminary step in the entire application method. The implementing entity for step S1 is the project management team or a designated BIM implementation team. Its core objective is to clarify the core requirements for the construction management of the water conveyance tunnel project and establish a clear and unified structured decomposition system for engineering objects.

[0040] In step S1, a systematic review of management operations is conducted, focusing on the inherent characteristics and management objectives of water diversion projects (with particular attention to the water conveyance tunnel section). This review aims to identify and define the key business areas that must be monitored and controlled throughout the entire project construction process, especially during the construction phase.

[0041] Reference Figure 2The management business process illustrated herein, through the analysis of project management needs, identifies and determines several core management business modules. In some embodiments of this invention, these management business modules may include, but are not limited to: an investment management module for controlling project costs, measuring payments, and cash flow; a schedule management module for planning, tracking, and controlling various activities and milestones in project construction; a quality management module for ensuring that the project entity and construction process meet design and specification requirements; a safety management module for identifying, assessing, and controlling various risks at the construction site to ensure the safety of personnel and property; an equipment management module for managing construction equipment; and a materials management module for managing the procurement, inventory, and consumption of materials and components required for the project. The identification and definition of these modules provide a basis for subsequent data classification, coding, and the construction of digital application modules.

[0042] Simultaneously, in step S1, the engineering unit division is carried out in parallel with or after the management business review. This step involves a top-down hierarchical and structured decomposition of all physical components of the water conveyance tunnel project based on relevant industry standards, design documents, and the specific conditions of the project itself.

[0043] Reference Figure 3 The diagram shown illustrates the logical structure of the engineering unit division, which follows a hierarchical system. In water conservancy and water diversion projects, this hierarchical system includes:

[0044] The top level is the unit project, which refers to a project with independent design documents and capable of independently exerting production capacity or benefits, such as "XX Water Conveyance Tunnel Main Project".

[0045] A unit project is divided into several sub-projects. Sub-projects are decomposed into unit projects according to factors such as project location, structural type, construction characteristics, or equipment type. Examples include "tunnel entrance section project", "tunnel body excavation and support sub-project", and "tunnel lining sub-project".

[0046] A sub-project is further divided into several unit projects. A unit project is a subset of a sub-project and serves as the basic unit for construction organization, quality inspection and evaluation, progress tracking, and project measurement and payment. For example, a "tunnel excavation and support sub-project" can be divided into multiple unit projects according to station mileage (e.g., every 50 meters or 100 meters) or specific construction sections.

[0047] Based on the unit project, it is further refined to the process level according to the needs of the construction technology. The process is a construction operation activity that constitutes the unit project and has clear technological boundaries and sequence. For example, a "tunnel excavation unit project (a certain pile number section)" may include specific processes such as "surveying and setting out", "drilling", "blasting", "ventilation and muck removal" and "initial support (such as shotcrete)".

[0048] It should be noted that the level of detail in the engineering unit division, especially at the unit project and process levels, plays a crucial role in the subsequent refined breakdown of the BIM model, the accurate assignment of codes, and the digital application of various management functions (such as process-level comparison between schedule plans and actual progress, and precise correlation between quality inspection results and unit projects). The implementation of step S1 lays the foundation for subsequent data standardization and model informatization.

[0049] In one specific embodiment of the present invention, step S2 involves classifying and encoding the management business and engineering unit data, which is performed based on the results of step S1. Its core objective is to establish a standardized and unified digital identification system for the various management information and engineering structural units identified in step S1, laying a solid data foundation for the effective association and system integration of the BIM model and business data.

[0050] In step S2, the specific data information involved in each management business module identified in step S1 is further refined and analyzed. (Refer to...) Figure 2 The business data processing process shown includes, but is not limited to: budget data, contract list data, measurement and payment data, and change negotiation data related to the investment management module; planned construction period data, actual start and completion date data, and critical path data related to the progress management module; inspection batch classification data, quality acceptance standard data, inspection record data, and non-conforming item data related to the quality management module; hazard identification data, safety technical briefing data, and hidden danger investigation record data related to the safety management module; equipment information data related to the equipment management module; and material specification and model data, purchase order data, inbound and outbound data, and consumption data related to the materials management module.

[0051] Based on a thorough analysis of the data information from the aforementioned business modules, this invention proposes the need for systematic information classification and coding. This coding work aims to assign a unique, structured code to each type of key business data item. The coding rules are formulated following principles such as uniformity, systematicity, scalability, identifiability, and stability. For example, investment data can be coded as investment data, progress data as progress data, quality data as quality data, safety data as safety data, equipment-related data as equipment data, and material-related data as material data, etc.

[0052] These different types of business data codes are not isolated but rather form a logically related coding system based on their inherent business logic. For example, the code for a quality inspection record may include or be associated with its corresponding unit project code, the corresponding schedule activity code, and related contract list item codes. In this way, based on each business data and its coding system, a structured and standardized business data output is ultimately formed, such as... Figure 2 The business data shown is the foundation for subsequent multi-dimensional information association and analysis.

[0053] Simultaneously, in step S2, the hierarchical structure data of the engineering units formed by the unit projects, sub-projects, unit projects, and processes divided in step S1 is encoded. This invention employs a hierarchical structure encoding method to accomplish this task. (Refer to...) Figure 3 The engineering division coding process shown is a coding method that can clearly reflect the position of each engineering unit in the overall engineering project structure and its subordinate relationship.

[0054] Specifically, a code segment is assigned to each unit project. A sub-project adds a code segment to the unit project code, a unit project adds another code segment to the sub-project code, and a work process adds a further code segment to the unit project code. For example, if a unit project is coded "DE01", a sub-project under it can be coded as "DE01-FB02", a unit project under that sub-project can be coded as "DE01-FB02-DY003", and a work process within that unit project can be coded as "DE01-FB02-DY003-GX04". This hierarchical coding is unique, facilitates computer recognition and processing, and supports subsequent data aggregation, filtering, and statistical analysis at different levels. Ultimately, this coding method forms the project division data coding results.

[0055] Through the implementation of step S2, this invention establishes two core coding systems: one is the business data coding result for management business data, and the other is the engineering division data coding result for engineering entity structure. These two coding results together constitute the "digital language" connecting the BIM model and engineering management business.

[0056] In one specific embodiment of the present invention, step S3 involves creating a BIM model based on classified and coded data and encoding and attaching the BIM model components. This step is a core technical step in achieving deep integration of BIM technology and engineering management business. This step aims to construct a three-dimensional digital model of the water conveyance tunnel that meets management requirements and assign the standardized coded information formed in step S2 to the model components, thus elevating the BIM model from a simple geometric representation to "BIM data" that carries rich business and structural information.

[0057] In step S3, the first step is to create a BIM model of the water conveyance tunnel. (Refer to...) Figure 4 The process shown illustrates that the creation of the BIM model in this invention is based on the modeling method and accuracy requirements determined by the business data coding results and engineering division coding results formed in step S2. This means that the granularity of the BIM model's breakdown, the level of detail of its components, and the types of information it contains serve the digital application needs of subsequent management operations.

[0058] For example, when the required precision of the engineering unit division determined in step S2 reaches the process level, the creation of the water conveyance tunnel BIM model undergoes corresponding refined subdivision. (Refer to...) Figure 6 The diagram illustrates the composition of the BIM model. In this case, the water conveyance tunnel BIM model can be broken down into sub-models representing different construction procedures or structural parts, such as the side arch excavation BIM model, the bottom slab excavation BIM model, the shotcrete (initial support) BIM model, the anchor bolt (support) BIM model, the secondary lining bottom slab BIM model, and the secondary lining side arch BIM model. These sub-models are created using mainstream BIM modeling software (such as Autodesk Revit, Bentley MicroStation, etc.). To ensure the correct assembly and integration of models from different disciplines and different segments, the modeling process should follow a unified modeling origin, coordinate system, and naming rules.

[0059] More importantly, during or after the creation of the water conveyance tunnel BIM model (or its sub-models and components), the business data codes and engineering unit division codes formed in step S2 are entered into the corresponding components of the BIM model. This is the so-called code linking or information assignment process. Through this process, each important component of the BIM model is given a standardized "identity" and "attribute information".

[0060] Reference Figure 5 The diagram shows the coding information when the BIM model of the water conveyance tunnel floor slab is divided into 1-meter segments. It illustrates that a specific floor slab BIM model component (representing a 1-meter-long segment) is assigned information such as "component name" (e.g., "floor slab"), "unit project code" (corresponding to the code of its respective unit project), "starting chainage," "ending chainage," "project category" (e.g., "lining project"), and "serial number." Among this information, the "unit project code" originates from the project division data coding results generated in step S2, while the coding of other business management-related information comes from the business data coding results.

[0061] The assignment of codes is achieved through the parametric function of the BIM modeling software itself. For example, custom parameters can be added to model families or component instances, and the codes generated in step S2 can be filled in as parameter values. For a large number of components, the API interface of the BBIM software can also be used to perform batch code assignment and verification through secondary development tools or scripts (such as Dynamo or Python scripts) to improve the efficiency and accuracy of assignment and verification.

[0062] Through the implementation of step S3, the BIM model, which originally mainly expressed geometric shapes and physical properties, is transformed into part of the BIM data because its components are assigned standardized business data codes and engineering division data codes. In other words, it becomes a digital model carrying business and structural information. This BIM data carrying coded information is the prerequisite and core for realizing automatic association, information linkage, and visualization applications between business data and BIM models in the subsequent digital construction management system.

[0063] In one specific embodiment of the present invention, step S4 involves inputting the sorted business data and BIM data carrying coded information into the digital building management system. This step is a core step in achieving information integration and building a unified management platform. This step aims to aggregate the standardized business data generated in the preceding steps and the coded BIM model data into a centralized digital management platform, and to establish the connection between the two using a unified coding system, providing data support for subsequent digital applications.

[0064] In step S4, a digital construction management system is first adopted as the data carrier and application platform. The digital construction management system in this invention refers to a construction management business system that supports BIM applications and is widely used in the construction phase of the engineering construction industry. Such systems typically have or can be configured with corresponding management modules, such as investment management, progress management, quality management, safety management, material management, and equipment management modules. Crucially, this digital construction management system should have BIM model data parsing capabilities, able to parse model data in mainstream BIM formats (such as IFC, RVT, DWG, etc.); it should also have BIM model output management functions to store, organize, and version control BIM models and their associated information; and it should have BIM model visualization display functions to enable operations such as browsing, querying, sectioning, and roaming of the model.

[0065] The business data originates from the results of step S2, namely, structured records and ledgers of various management business information with unified codes. The BIM data carrying coding information originates from the results of step S3, namely, the BIM model of the water conveyance tunnel with components assigned business data codes and engineering division codes. This data needs to be input into the selected digital construction and management system.

[0066] The data input process includes: in the early stages of the project or during the system deployment phase, batch importing of basic data, such as importing a complete engineering division coding system, a business data coding rule library, an initial version of the water conveyance tunnel BIM model, contract list data, and a preliminary overall construction schedule.

[0067] As the project progresses, newly generated business data and updated BIM model data are continuously input into or synchronized to the digital construction management system during construction. For example, daily or weekly progress reports, on-site quality inspection records, safety inspection results, material entry and exit records, and actual cost data are entered into the system according to established coding rules. When the BIM model is updated due to design changes or construction refinement, the updated model is also imported into the system.

[0068] To ensure the timeliness, accuracy, and effectiveness of data in the digital construction management system, a working mechanism for data improvement, modification, and optimization has been established. This mechanism includes regular data verification, data cleaning, version management, and access control to ensure that data quality meets the needs of management applications.

[0069] In the digital construction management system, business data and BIM data are effectively linked through the business data codes and project division data codes established and uniformly applied to business data and BIM components in step S2. Using these common codes, the system automatically or semi-automatically links a business data record (e.g., a quality inspection report for a unit project) to the corresponding component or area in the BIM model (e.g., the BIM model segment corresponding to that unit project).

[0070] Through the implementation of step S4, scattered business data and BIM model data are collected, integrated, and correlated within the digital building management system, forming a holographic data network with BIM models as the visualization carrier, interconnected through a unified coding system, and possessing inherent logical relationships. This data network forms the foundation for subsequent development of various BIM-based digital applications for business management.

[0071] In a specific embodiment of the present invention, step S5 is to carry out BIM-based digital application of business management in the digital construction and management system. This step aims to use the business data and BIM data collected and associated in step S4 to realize the digital, visual and intelligent upgrade of various core management businesses of the water conveyance tunnel project through the digital construction and management system.

[0072] After business data and BIM data carrying coding information are input into the digital building management system and effectively linked based on a unified coding system, this integrated data supports functions such as visualization, data analysis, decision support, and information traceability, laying the foundation for carrying out digital applications of various management businesses.

[0073] Reference Figure 7 The illustrated application demonstrates the digital application of various management functions within the digital construction management system. For example, in investment management, the system automatically compares completed and accepted components in the BIM model (identified by their associated project classification codes) with quantities in the contract list (linked by business data codes) to assist in quantity calculation and support visualized measurement and payment review. Simultaneously, actual cost data is collected by code and linked to project units in the BIM model, enabling three-dimensional visualization analysis of cost composition and dynamic comparison between preliminary estimates and actual costs.

[0074] In terms of digital applications for schedule management, BIM model components are associated with work activities (also assigned corresponding codes) in the schedule planning software through their engineering partition codes, enabling 4D construction simulation. This simulation is used for the visualization, optimization, and potential clash detection of construction plans. Based on the actual construction progress data reported daily or periodically (which records the completion status of specific engineering unit codes), completed, under construction, or lagging components are dynamically rendered (e.g., by changing color or transparency) on the water conveyance tunnel BIM model. For example, the construction progress of the corresponding tunnel section is displayed by unit length (e.g., meters) to provide an intuitive progress display.

[0075] In terms of digital application of quality management, a two-way link is established between various quality inspection records, image data, test reports, etc. (all of which include business data codes and project division codes) and specific components or unit projects in the BIM model. When users click on the BIM model corresponding to a unit project that has completed the acceptance and evaluation in the digital construction management system, they can view and trace the quality control records, problems found, and related acceptance and evaluation data of that unit project during the construction process.

[0076] In terms of digital applications for safety management, the locations of identified major hazards are marked in the BIM model (associated with corresponding safety business codes), and dynamic safety risk alerts are provided in conjunction with the construction schedule. Furthermore, when the system integrates on-site personnel positioning technologies (such as GPS and UWB), the specific construction pile number and location within the tunnel of the construction personnel are calculated using the global coordinate system of the BIM model and real-time coordinate data uploaded by the personnel positioning devices. This assists in monitoring and issuing early warnings for personnel entering and exiting specific hazardous areas.

[0077] In addition to the main management functions mentioned above, the method of the present invention also supports digital applications for materials management (e.g., tracking the procurement, warehousing, and requisition status of specific materials associated with BIM components) and digital applications for equipment management (e.g., monitoring the installation and commissioning progress of large equipment associated with equipment components in the BIM model).

[0078] Furthermore, this invention can also realize the comprehensive digital application of multiple management functions in a digital construction management system. For example, it can build an integrated project management dashboard or dashboard, summarize and display key performance indicators (KPIs) from different business modules, and link them with the BIM model to provide project managers with a comprehensive and real-time view of the project status and decision support information.

[0079] Through the implementation of step S5, the BIM model of the water conveyance tunnel becomes the core data carrier and collaborative work platform that drives and supports engineering management operations. It effectively combines BIM technology with the actual needs of engineering management, thereby improving the construction management level, decision-making efficiency and risk control capabilities of engineering projects, and laying the data and application foundation for realizing digital twin water conservancy projects.

[0080] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
