Description

Technical Field

[0001] This application relates to the field of construction technology, and in particular to a method and apparatus for representing linear engineering construction progress based on three-dimensional visualization technology. Background Technology

[0002] Linear engineering projects refer to engineering projects that are linearly distributed, such as railways, highways, oil and gas pipelines, canals, pipelines, urban integrated pipe networks, power transmission lines, and cableways. Linear engineering projects are characterized by long construction lines, complex social and natural environments, high construction difficulty, long construction periods, high project costs, and significant social impact, requiring strong organizational and coordination capabilities. The core focus of linear engineering project organization and management is the management of the construction schedule. This requires the development of a scientific and reasonable construction schedule, close coordination of various tasks, and orderly organization of various resources to ensure the project progresses smoothly according to plan.

[0003] The existing method uses Gantt charts to represent the start and end points of tasks. This is simple and intuitive, reflecting the logical relationships between tasks and, for complex projects, showing the relationships between different levels of tasks. However, its shortcomings lie in the fact that large linear projects often involve hundreds or even thousands of tasks with complex logical relationships. Non-professionals or those not in charge of the project may find it difficult to understand these internal relationships, and problems in the plan are hard to spot. While the critical path can be identified, it's difficult to grasp the overall construction schedule from a macro perspective, and it doesn't provide a direct view of the construction progress or the deployment of construction equipment.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] This specification provides an embodiment of a method for representing linear engineering construction progress based on 3D visualization technology. Please refer to [link / reference]. Figure 1 As shown, it includes: S1. Obtain a linear engineering plan table, obtain several sub-project planning points based on the linear engineering plan table, obtain several sub-item planning points based on the sub-project planning points, and obtain the smallest unit construction procedure based on the sub-item planning points. The linear engineering plan table includes construction equipment parameters and quantities. The linear engineering project is broken down step by step and item by item, down to the smallest unit of construction procedure.

[0032] Linear engineering projects undergo structural decomposition, breaking down the entire project into sub-projects and individual items. Items impacting the overall construction schedule are further decomposed into the smallest unit of work for schedule planning, and then visualized using 3D models. Specifically, CAD design drawings are imported into Revit or other 3D modeling software for model creation at a 1:1 scale to ensure accuracy. Temporary structures primarily used on-site, such as drilling platforms, pier caps, cofferdams, temporary steel trestle bridges, pier formwork, and bridge supports, are all modeled using Revit or other 3D software. Large specialized construction equipment used on-site is modeled using equipment drawings provided by the manufacturers. Conventional large equipment such as excavators and crawler cranes can be purchased from professional 3D websites.

[0033] S2. Obtain the minimum unit construction procedure duration and construction specification requirements; S3. Based on the equipment parameters and quantity, as well as the construction specifications, obtain the construction period for the minimum unit of construction process. S4. Obtain the project schedule for each item based on the construction period of the smallest unit of construction procedure, and obtain the project schedule for each section based on the project schedule for each item. S5. Generate a three-dimensional visual construction schedule based on the planned points and durations of each sub-project.

[0034] In one possible implementation, generating a 3D visualized construction schedule based on the planned points and durations of each sub-project includes: horizontally setting several planned points of the sub-project along the route mileage on a horizontal coordinate axis to generate a mileage-route horizontal coordinate system; vertically setting the durations of the corresponding sub-project planned points on a vertical coordinate axis to generate a time coordinate system; and generating a 3D visualized construction schedule based on the mileage-route horizontal coordinate system and the time coordinate system. For example: A 3D visualized process schedule is created and controlled by equipment resources. For each construction process, relevant construction machinery and equipment are configured, and the time required is determined by the equipment's production efficiency. The process duration is determined based on equipment parameters and quantities, and controlled by equipment resources. All of this is presented in a 3D visualized format, making it very easy to understand. Furthermore, through parameterized settings, the visualized, digitally driven process schedule can be adjusted in real time.

[0035] Develop a 3D visualization schedule for each sub-project. The development of the construction schedule for each sub-project at each point along the mileage direction of the linear project should be determined based on the number of sub-projects, equipment, and specification requirements at that point. Each sub-project schedule should be displayed using 3D visualization.

[0036] Develop a 3D visualization construction schedule for each section of the project along the longitudinal axis (Y-axis) at each point along the mileage direction. For each project point along the mileage direction, accumulate the time schedules of different sub-projects from bottom to top in chronological order to determine the completion period of the section project at that point. Develop a three-dimensional visualization-driven overall construction schedule for linear engineering projects. Using the vertical axis (Y-axis) as the time axis and the horizontal axis (X-axis) as the linear spatial (mileage) axis, based on the construction periods of each sub-project, adopt a reverse scheduling approach, compiling the schedule from top to bottom. The schedule fully considers the turnover and reuse of resources such as equipment, maximizing the efficiency of equipment and human resources. Through computer optimization, it avoids various resource wastes or shortages that could prevent meeting the contractually required construction period.

[0037] In a specific implementation, before developing a construction schedule, the linear engineering project is decomposed into sections from surface to line and from line to point (see...). Figure 2 ),like Figure 2A simplified linear project can be divided into ten points horizontally (X-axis) from P1 to P10. At point P1, it can be further divided vertically (Y-axis) into sub-projects such as bored piles, pile caps, piers, and superstructure. When preparing the construction schedule, the sub-projects are first decomposed into work processes (see...). Figure 3 This connects linear engineering projects from points to lines, and from lines to surfaces, into a unified whole (see...). Figure 4 , 5 2); Linear projects are generally not distributed in a straight line, but rather in a linear pattern with many turns and deviations. To address this, the project will be straightened according to the route mileage and placed on the horizontal (X-axis) coordinate axis, with the main sub-projects and sub-projects placed on the mileage line. Each major sub-project is decomposed into work processes, and each construction process is visualized using a 3D model. The completion time of each process is determined based on the equipment performance. Parametric digitally driven 3D software is used to integrate the processes of each sub-project. By parametrically changing the parameters of one process, the time of other processes will be linked together. The sub-project work sequence plan is mainly driven by equipment resources. For example, the sub-project work sequence for bored piles mainly includes installing the casing, drilling, lowering the reinforcing cage, and pouring concrete. Each process is equipped with relevant equipment, and the time required is determined by the production efficiency of the equipment. All of these are represented in a 3D visualization format, which is very easy to understand. Furthermore, through parameter settings, adjustments can be made in real time (see...). Figure 6 The process and technology will be displayed in the form of animation, which can reflect the construction methods of each sub-project. The animations of the process and technology of each sub-project will be compiled to form a process animation library.

[0038] The construction schedule for each sub-item of the linear project along the mileage direction is determined based on the number of sub-items, equipment, and specification requirements at that point. For example, there are 6 bored piles at point P1 (see...). Figure 4 According to the specifications, two piles must be constructed simultaneously at a certain distance. This determines the maximum number of machines that can be placed. The construction period for the bored piles at this location is then determined based on the number of machines and their production efficiency (see [link]). Figure 7 ).

[0039] For each point in a linear project, the total completion time of each sub-project along the vertical axis (Y-axis) is calculated, which is the construction schedule plan for that sub-project at that point.

[0040] By accumulating the time plans of different sub-projects from bottom to top in chronological order, the completion period of the sub-project at that point can be determined.

[0041] Develop an overall construction schedule for the linear project, using the vertical axis (Y-axis) as the time axis and the horizontal axis (X-axis) as the linear spatial (mileage) axis. Based on the construction periods of each sub-project, develop an overall construction schedule for the linear project (see...). Figure 8 ).

[0042] Methodology: The schedule is planned from top to bottom using a reverse scheduling approach. The schedule fully considers the turnover and reuse of resources such as equipment, and makes full use of the efficiency of equipment and human resources. The schedule is optimized by computer to avoid various wastes or shortages of resources that do not match the contractual schedule requirements.

[0043] Presentation format: The vertical axis represents time, with a sliding time slider that can be moved up or down to display the specific year, month, and day, reflecting the passage of time. The horizontal axis represents linear mileage, with major engineering projects distributed at corresponding mileage nodes. Engineering projects have three display states: 1) not displayed when construction has not started; 2) displayed in blue when under construction; and 3) displayed in red when completed. Major construction equipment is also displayed on the map, reflecting its construction status and movement trajectory at corresponding times. The equipment movement trajectory can be set to either visible or hidden.

[0044] Develop other 3D visualization professional construction schedules, and develop 3D visualization professional construction schedules with different requirements based on the characteristics and needs of the project.

[0045] A 3D visualization of the key milestone schedule for an engineering project is created by extracting the construction status of milestone completion points from the overall linear project construction schedule and compiling a 3D milestone schedule (see...). Figure 9 This allows us to understand the on-site construction status at each milestone, drawing attention from all parties and preventing fines due to improper work arrangements that could lead to failure to meet milestones.

[0046] A three-dimensional visualization plan for the lifting of steel beams using large floating cranes was developed for the bridge project, addressing the large number of steel beams to be lifted at sea and the complexity of the lifting sequence. (See [link]) Figure 10 The steel beams to be lifted by the floating crane are divided into sections and marked with different colors. The horizontal direction indicates the position of the steel beams, and the vertical direction indicates the time of beam erection.

[0047] A three-dimensional time-mileage construction progress chart is used, with the horizontal axis representing project mileage and the vertical axis representing construction period. This time-mileage chart allows for checking the rationality of the plan and visually and intuitively reflects the work content and sequence of each construction and installation component (see...). Figure 11 This allows for an overall grasp of the project's construction schedule and pace, serving as a supplement to the Gantt chart plan.

[0048] Actual progress is shown in comparison with the plan.

[0049] (1) Compile a resource-based three-dimensional image progress chart It not only reflects the on-site construction progress, but also the resource input (see...). Figure 12 This involves comparing the resources invested with those in the plan to identify and correct any problems.

[0050] By filling in information on human, material, and machine resources and displaying the progress, the actual progress can be compared with the plan, which will allow for a more accurate and efficient grasp of the on-site situation, timely identification of problems, and the proposal of effective countermeasures.

[0051] The actual progress can be displayed through animation, and a three-dimensional progress map is prepared every week to intuitively grasp the on-site construction progress and the status of plan completion. The focus of the progress map is different in different stages of construction. During the bored pile construction stage, the equipment and personnel invested in the bored piles of the main bridge are highlighted, while during the pier cap construction stage, the construction process of the pier cap is highlighted.

[0052] The start and completion dates, the input of personnel, materials and equipment, and the progress of work completion will be fed back to the 4DBIM cloud platform in real time. By leveraging the advantages of information integration, the distribution of on-site resources and the construction status can be well grasped.

[0053] (2) Use VR / AR technology to reflect the construction progress status at the construction site. VR / AR technology can be used to reflect the construction progress status at the construction site, allowing for an immersive experience of the construction progress. A VR project showcasing the construction progress of bored piles was created using BIM technology (see...). Figure 13 The system also includes AR technology for the construction progress of the main bridge girder of the interchange. Wearing a VR headset allows for an immersive experience, displaying the type and quantity of devices along with text descriptions. Users can also view the progress of bored piles on their mobile phones. (3) Comparison of BIM model plan and actual on-site progress pictures By comparing the BIM model with actual on-site progress photos, the gap between the planned and actual progress can be seen very clearly and intuitively.

[0054] Advantages of linear engineering 3D visualization digital-driven construction schedule planning: First, it can visually and intuitively demonstrate the progress and completion sequence of linear engineering projects over time, providing an intuitive understanding of the rationality of the project construction arrangement. Second, it can display the quantity, working time, and operating trajectory of major construction machinery and equipment. Third, it can decompose sub-projects on the critical path into work processes, determine the minimum construction unit's working time through the equipment input of construction processes, and thus determine the overall construction period. By using a reverse scheduling approach, the construction period can be optimized, resources can be allocated rationally, and resource waste can be avoided. Fourth, through the time slider, the construction progress plan can be freely simulated forward or backward, and by setting parameterized work process durations, the construction date can be easily adjusted, enabling digital-driven operation.

[0055] like Figure 14 As shown, an apparatus for representing linear engineering construction progress based on three-dimensional visualization technology is characterized by comprising: The decomposition module 301 is used to obtain a linear engineering plan table, obtain several sub-project planning points based on the linear engineering plan table, obtain several sub-item planning points based on the sub-project planning points, and obtain the smallest unit construction procedure based on the sub-item planning points. The linear engineering plan table includes construction equipment parameters and quantities. Processing module 302 is used to obtain the minimum unit construction procedure duration and construction specification requirements; obtain the minimum unit construction procedure duration based on equipment parameters and quantity and construction specification requirements; obtain the sub-item plan point duration based on the minimum unit construction procedure duration; and obtain the sub-section plan point duration based on the sub-item plan point duration.
