Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge construction, and in particular to a construction progress control method and system based on a bridge elevation drawing. BACKGROUND

[0002] Railway bridge engineering is a complex project, and the construction process may be affected by factors such as weather and material supply, resulting in changes in progress. Therefore, construction organization management needs to flexibly adjust the plan according to the actual situation on site to ensure that the project is completed on time. Dynamic progress adjustment can respond to unexpected problems in time, reduce the risk of delay, and ensure the overall progress. Therefore, progress management is crucial in railway bridge engineering construction and directly affects the smooth completion of the project.

[0003] Currently, existing bridge engineering progress management includes relying on universal progress management software (such as Microsoft Project, Primavera, etc.) to plan and track the construction progress of bridges. These progress management software creates progress plans, including task allocation, progress scheduling, etc., to help managers monitor progress in real time and make corresponding adjustments.

[0004] However, the existing progress management tools have insufficient functions, cannot meet the actual needs of users, lack appropriate graphical display functions and intuitive charts and dashboards, and have poor tracking functions and real-time updated data visualization effects, which may make it difficult for users to grasp the status and development trend of the project in a timely manner. SUMMARY

[0005] In view of this, the embodiments of the present application provide a construction progress control method and system based on a bridge elevation drawing to eliminate or improve one or more defects in the prior art. The existing progress management tools lack appropriate graphical display functions and intuitive charts and dashboards, and have poor tracking functions and real-time updated data visualization effects, which may make it difficult for users to grasp the status and development trend of the project in a timely manner.

[0006] One aspect of the present application provides a construction progress control method based on a bridge elevation drawing, which includes the following steps: Based on the current progress information of the construction bridge, the bridge elevation drawing corresponding to the construction bridge is colored, and the colored bridge elevation drawing is displayed on the progress display interface. The current progress information includes the construction status of each bridge structure on the construction bridge, and different construction statuses correspond to different coloring colors. In the case that there is a special bridge structure on the construction bridge, the construction period of the special bridge structure is deduced according to a planned progress deduction mode to obtain a deduction completion time corresponding to the special bridge structure; the planned progress deduction mode refers to a mode of predicting the progress according to a preset deduction algorithm in combination with an original construction plan and construction resources; Based on the difference between the deduction completion time, the planned completion time, the time for the beam truck to pass through, and the time for track laying, the progress warning of the special bridge structure is determined. Based on the progress warning, the bridge elevation drawing is colored, and the colored bridge elevation drawing is displayed on the progress warning interface; different progress warnings correspond to different colored colors.

[0007] In some embodiments of the present application, the construction bridge further includes an upper bridge structure and a lower bridge structure; in the case that the construction period deduction instruction corresponding to the upper bridge structure or the lower bridge structure is received, the method further includes: According to the construction period deduction mode and the target bridge structure indicated by the construction period deduction instruction, the progress of the target bridge structure is deduced to obtain a target deduction completion time corresponding to the target bridge structure; the construction period deduction mode includes a planned progress deduction mode, a low-index deduction mode, a medium-index deduction mode, or a high-index deduction mode; the low-index deduction mode refers to a mode of predicting the progress according to a preset deduction algorithm under the condition of limiting construction resources; the medium-index deduction mode refers to a mode of predicting the progress according to a preset deduction algorithm under the condition of normal construction resources; the high-index deduction mode refers to a mode of predicting the progress according to a preset deduction algorithm under the condition of high construction resources; Based on the difference between the target deduction completion time and the planned completion time corresponding to the target bridge structure, the progress warning of the target bridge structure is determined.

[0008] In some embodiments of the present application, in the case that the progress warning is lagging or seriously lagging, after the progress warning of the special bridge structure is determined based on the difference between the deduction completion time, the planned completion time, the time for the beam truck to pass through, and the time for track laying, the method further includes: According to the low-index deduction mode, the medium-index deduction mode, and the high-index deduction mode, the construction period of the special bridge structure is re-deduced to obtain a first deduction completion time corresponding to the low-index deduction mode, a second deduction completion time corresponding to the medium-index deduction mode, and a third deduction completion time corresponding to the high-index deduction mode; In the case that some time points in the first deduction completion time, the second deduction completion time, and the third deduction completion time are earlier than the deduction completion time, according to the deduction mode corresponding to these time points earlier than the deduction completion time, a prompt information is generated, and the prompt information is used to prompt the user to adjust the construction plan and the construction resources according to the corresponding deduction mode.

[0009] In some embodiments of the present invention, the preset inference algorithm includes a network planning-based inference algorithm, a resource constraint-based inference algorithm, or a machine learning-based inference algorithm.

[0010] In some embodiments of the present invention, the progress warning for special bridge structures is determined based on the differences between the estimated completion time and the planned completion time, the girder erection vehicle passage time, and the track laying time, including: If the projected completion time does not exceed the planned completion time, the progress warning is considered normal. If the projected completion time exceeds the planned completion time and the first time difference between the projected completion time and the girder erection vehicle's arrival time is greater than or equal to 28 days, the progress warning is considered delayed; if the first time difference is less than 28 days, the progress warning is considered severely delayed. If the girder erecting vehicle fails to pass through a special bridge structure, the projected completion time exceeds the planned completion time, and the second time difference between the projected completion time and the track laying time is greater than or equal to 28 days, the progress warning is considered delayed; if the second time difference is less than 28 days, the progress warning is considered severely delayed.

[0011] In some embodiments of the present invention, after determining the progress warning for special bridge structures based on the differences between the estimated completion time and the planned completion time, the girder erection vehicle passage time, and the track laying time, the method further includes: Based on progress warnings and current progress information, construction status statistical charts and tables are drawn. The construction status statistical charts include bar charts and pie charts. The bar charts and construction status statistical tables are used to display the construction progress of each bridge structure, and the pie charts are used to display the progress warning ratio of special bridge structures. The construction status statistics chart and construction status statistics table are displayed on the bridge statistics interface.

[0012] In some embodiments of the present invention, the progress display interface also includes a construction status list corresponding to each bridge structure; in the progress display interface, the display position of the construction status list matches the position of the elevation view corresponding to each bridge structure one by one.

[0013] In some embodiments of the present invention, based on the current progress information corresponding to the construction bridge, the bridge elevation view corresponding to the construction bridge is colored, and the colored bridge elevation view is displayed after the progress display interface, which further includes: Upon receiving a hover trigger command or click trigger command applied to the bridge elevation drawing, an information pop-up window is generated in the progress display interface. The information pop-up window displays the bridge structure information and current progress information of the bridge structure indicated by the hover trigger command or click trigger command.

[0014] Another aspect of the present invention provides a construction progress control system based on bridge elevation drawings, the system comprising: The information maintenance module is used to color the bridge elevation view corresponding to the construction bridge based on the current progress information of the construction bridge, and display the colored bridge elevation view on the progress display interface; the current progress information includes the construction status of each bridge structure on the construction bridge, and different construction statuses correspond to different coloring colors. The schedule prediction module is used to predict the schedule of special bridge structures under construction by using a planned schedule prediction mode. The planned schedule prediction mode refers to the mode of predicting the progress based on a preset prediction algorithm combined with the original construction plan and construction resources. The progress warning module is used to determine the progress warning for special bridge structures based on the difference between the estimated completion time and the planned completion time, the girder erection vehicle passage time and the track laying time. Based on the progress warning, the bridge elevation drawing is colored and displayed on the progress warning interface. Different progress warnings correspond to different coloring colors.

[0015] In some embodiments of the present invention, the system further includes: The progress statistics module is used to draw construction status statistics charts and tables based on progress warnings and current progress information. The construction status statistics charts include bar charts and pie charts. The bar charts and the construction status statistics tables are used to display the construction progress of each bridge structure, and the pie charts are used to display the progress warning ratio of special bridge structures. The construction status statistics charts and tables are displayed on the bridge statistics interface.

[0016] The construction progress control method and system based on bridge elevation drawings of this invention can solve the problems of existing progress management tools lacking appropriate graphical display functions and intuitive charts and dashboards, and having poor tracking functions and real-time data visualization effects, making it difficult for users to grasp the status and development trend of the project in a timely manner. By dynamically coloring the bridge elevation drawings based on the current progress information of the bridge under construction, displaying the colors corresponding to different construction states, a clear and intuitive progress visualization effect is provided. When encountering special bridge structures, a planned progress extrapolation mode is adopted to predict the completion time of special structures based on the original construction plan and resource extrapolation progress, and compare it with the planned completion time. By comparing construction time, girder erection vehicle transit time, and track laying time, progress warnings are generated. These warnings are then displayed in color on the progress warning interface, helping users quickly identify project status and progress trends, improving the efficiency of progress tracking and real-time updates, and ensuring users can keep abreast of project progress. Simultaneously, visualization methods supplement and improve basic data and historical progress information to meet the requirements of refined bridge management, providing visual progress charts, schedule projections, progress warnings, and statistical information. This enhances the intuitiveness and ease of use of progress and warning displays, reduces reliance on tedious text or numerical analysis, and thus promotes efficient information transmission and decision-making.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0023] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0024] In the following description, embodiments of the invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0025] The following section provides a detailed description of the construction progress control method based on bridge elevation drawings provided in this application.

[0026] like Figure 1 As shown, an embodiment of this application provides a construction progress control method based on bridge elevation drawings, which is used in electronic devices. These electronic devices include, but are not limited to, computers, tablets, or mobile phones; this embodiment does not limit the type of electronic device. The method includes at least steps S101 to S104: Step S101: Based on the current progress information of the construction bridge, color the bridge elevation view corresponding to the construction bridge, and display the colored bridge elevation view on the progress display interface.

[0027] In some embodiments of the present invention, the current progress information includes the construction status of each bridge structure on the construction bridge, wherein each bridge structure of the construction bridge includes an upper bridge structure, a lower bridge structure, and a special bridge structure.

[0028] The superstructure of a bridge refers to the main load-bearing part of the bridge, typically including the bridge deck and various components supported on piers and abutments (including piers and abutments). Examples include: bridge deck panels, main beams, crossbeams, bridge deck pavement, and bridge railings. The substructure of a bridge refers to the part that supports the superstructure, mainly including piers, pile foundations, ground, and foundations that support and bear the load.

[0029] Special bridge structures refer to bridges with unique characteristics or special requirements in terms of design, material selection, construction methods, and construction technology, such as continuous beam structures, arch structures, cable-stayed structures, or suspension structures.

[0030] Accordingly, the bridge elevation drawings include elevations corresponding to the superstructure, substructure, and special structures. Using an intuitive progress chart, a single bridge elevation drawing comprehensively displays the elevations of all bridge structures. Based on the current progress information of each structure, the elevation drawings are colored to represent the construction status, breaking down the construction progress of each sub-project and providing timely auxiliary decision-making support to construction and management units.

[0031] In some embodiments of the present invention, the current progress information is used to indicate the construction status of each bridge structure on the construction bridge, including the constructed state, the under-construction state, and the non-construction state. The elevation views corresponding to each bridge structure are colored according to the construction status indicated by the current progress information, with different colors corresponding to different construction states. Then, the colored bridge elevation views are displayed in the progress display interface. By using coloring to represent the current construction status of each bridge structure, the construction stage of each bridge structure can be clearly displayed, improving the visualization of information.

[0032] For example, the color corresponding to the "under construction" state is green, the color corresponding to the "under construction" state is red, and the color corresponding to the "not under construction" state is white.

[0033] In some embodiments of the present invention, the current progress information is the current progress information of each bridge structure of the construction bridge that is manually entered by the user.

[0034] In practice, the current progress information can also be obtained from other construction status management platforms or systems (such as the basic data platform of the railway engineering information management platform, or the electronic construction log management system of the railway engineering information management platform) to obtain the current progress information of each bridge structure of the construction bridge. This embodiment does not limit the method of obtaining the current progress information.

[0035] In some embodiments of the present invention, the current progress information also includes the construction date corresponding to the construction status of each bridge structure, so as to indicate the start date or completion date of construction of each bridge structure. By combining the construction date information of each bridge structure, the construction progress of each bridge structure can be presented more accurately.

[0036] Meanwhile, to facilitate users' real-time viewing of bridge structure information and related construction progress, when viewing bridge elevation drawings, users can click on a specific bridge structure's elevation drawing using a mouse or touchscreen, or hover the mouse pointer over it to trigger a pop-up window displaying detailed information and current construction progress. This ensures real-time accuracy and helps users quickly understand the construction progress and timelines for each bridge structure. For example, taking a completed pier as an example, the pop-up window includes the bridge structure's name, actual start date, actual completion date, pier width, and pier height.

[0037] Specifically, based on the current progress information of the bridge under construction, the bridge elevation view corresponding to the bridge under construction is colored, and the colored bridge elevation view is displayed after the progress display interface. It also includes: when a hover trigger command or click trigger command is received on the bridge elevation view, an information pop-up window is generated in the progress display interface. The information pop-up window is used to display the bridge structure information and current progress information of the bridge structure indicated by the hover trigger command or click trigger command.

[0038] Furthermore, to allow users to more intuitively connect the construction status and specific location of each bridge structure when viewing the progress display interface, a list of construction statuses for each bridge structure is included. The display position of the construction status list matches the position of the corresponding elevation view for each bridge structure. This allows users to quickly identify the progress related to each bridge structure without tedious searching and switching operations, improving the interface's visualization and operational efficiency. At the same time, the information display is more organized, the interface is clearer, visual clutter is reduced, and user convenience and overall user experience are enhanced.

[0039] Step S102: In the case of special bridge structures on the construction bridge, the construction period of the special bridge structures is simulated according to the planned progress simulation mode to obtain the simulated completion time of the special bridge structures.

[0040] The planned progress prediction mode refers to a mode that predicts the progress based on a preset prediction algorithm combined with the original construction plan and construction resources. The original construction plan includes the original start date and end date of construction; the original resources include human resources, equipment resources, or material resources, etc.

[0041] In some embodiments of the present invention, the preset inference algorithm includes a network-based algorithm, a resource-constrained scheduling algorithm, or a machine learning-based algorithm.

[0042] Network planning-based extrapolation algorithms typically rely on the Critical Path Method (CPM) or the Program Evaluation and Review Technique (PERT). First, based on the construction plan, project tasks and their interrelationships (such as prerequisites and successors) are determined, and a network diagram is drawn. Next, estimated start and end times are assigned to each task, and the duration of each task is marked. Then, the critical path is determined by calculating the earliest start time, earliest finish time, latest start time, and latest finish time for each task. Tasks on the critical path represent bottlenecks in the overall project schedule. Finally, through extrapolation algorithms, the progress of construction tasks is predicted based on different time phases, dynamically adjusting the project's estimated completion time, identifying potential delays, and dynamically adjusting task priorities and resource allocation based on actual resource input and task execution, updating the network diagram and critical path.

[0043] Resource-constrained extrapolation algorithms consider the dependencies between different construction tasks and the impact of resource availability (such as manpower, equipment, and materials) on construction progress, predicting progress by simulating actual resource allocation. First, the types and quantities of resources required for all construction tasks are determined, including manpower, equipment, and materials, and resource modeling is performed. Next, a resource constraint network is established, similar to network planning, but with resource constraints added between each construction task, such as whether the required equipment for a task is sufficient or whether there are available personnel for a certain skill. Then, based on the urgency of the construction tasks and resource availability, priorities are assigned to each task, prioritizing tasks with tight resource requirements. The start time and duration of construction tasks are scheduled according to resource constraints to avoid resource conflicts. For situations with insufficient resources, progress can be adjusted by postponing certain tasks or adjusting their resource requirements. Finally, through simulation and extrapolation, the completion time of construction tasks under different resource configurations is predicted in real time.

[0044] Machine learning-based inference algorithms use historical data to train models, automatically identifying potential patterns in project progress and predicting future construction schedules. Commonly used machine learning methods include regression analysis, decision trees, and neural networks. First, historical project data is collected, including actual task durations and resource usage, and then cleaned and preprocessed. Next, based on data characteristics and problem requirements, relevant features (such as task type and resource input) are selected as input features, and an appropriate machine learning algorithm is chosen for model training to optimize predictive accuracy. Then, methods such as cross-validation are used to evaluate the model's predictive performance, ensuring its generalization ability to unseen data. Finally, the model is applied to the current project, inputting the project's planned data and resource information; the model then predicts task progress based on the patterns learned during training.

[0045] In some embodiments of the present invention, the completion date of subsequent special bridge structures can be deduced by the planned and actual progress. The construction unit and the owner management unit can keep abreast of the bridge construction progress information, make reasonable resource arrangements in advance according to the construction period, and ensure that the special structures in the railway bridge are successfully completed on the specified date according to the construction organization plan and that the bridge is successfully connected.

[0046] Step S103: Based on the differences between the projected completion time and the planned completion time, the girder erection vehicle passage time and the track laying time, determine the progress warning for special bridge structures.

[0047] The planned completion time refers to the scheduled completion time of the entire special bridge structure. The girder erection vehicle passage time refers to the time point during actual construction when the girder erection vehicle passes through or completes the erection of a girder segment. The track laying time refers to the time point during bridge construction when the tracks are laid.

[0048] Specifically, based on the differences between the projected completion time and the planned completion time, the girder erection vehicle's transit time, and the track laying time, the progress warning for special bridge structures should include at least the following situations: The first scenario is that if the projected completion time does not exceed the planned completion time, the progress warning is considered normal.

[0049] The second scenario is that if the projected completion time exceeds the planned completion time, and the first time difference between the projected completion time and the girder erection vehicle's transit time is greater than or equal to 28 days, the progress warning is considered delayed.

[0050] If the time difference is less than 28 days, the progress warning indicates a serious delay.

[0051] The third scenario is that if the girder erecting vehicle fails to pass through a special bridge structure, the projected completion time exceeds the planned completion time, and the second time difference between the projected completion time and the track laying time is greater than or equal to 28 days, the progress warning is delayed.

[0052] If the second time difference is less than 28 days, the progress warning indicates a serious lag.

[0053] After obtaining progress warnings for special bridge structures during construction through schedule simulation, it is necessary to visualize the progress warning ratios for each special bridge structure to more intuitively display their proportions. This visualization involves creating a pie chart showing the proportions of various progress warnings. The pie chart uses the size and scale of the sectors to visually represent the percentage of each type of progress warning. Each sector represents a progress status (e.g., "normal," "delayed," "severely delayed," etc.), allowing project managers to quickly understand the overall progress distribution and clearly see which parts of the progress are experiencing problems and the severity of those problems. Simultaneously, to facilitate project managers' rapid understanding of the project's status and trends, as well as real-time updates and tracking of project progress and key indicators, charts are also needed to visually represent project progress and key indicators.

[0054] Specifically, after determining the progress warning for special bridge structures based on the differences between the projected completion time and the planned completion time, the girder erection vehicle passage time, and the track laying time, the process also includes: drawing construction status statistical charts and construction status statistical tables based on the progress warnings and current progress information; the construction status statistical charts include bar charts and pie charts, which are used to display the construction progress of each bridge structure, and the pie charts are used to display the progress warning ratio of special bridge structures; and the construction status statistical charts and construction status statistical tables are displayed on the bridge statistics interface.

[0055] In some embodiments of the present invention, the progress warning may further include progress warnings for other structures in the construction bridge besides special structures, including progress warnings for the superbridge structure and progress warnings for the subbridge structure. A progress prediction is performed on a specified superbridge structure or a specific subbridge structure using a planned progress projection model. The projected completion time of the structure is obtained and compared with the planned completion time to generate a progress warning, enabling project managers to adjust construction plans and resources based on the progress warning.

[0056] In addition, in some embodiments of the present invention, the schedule prediction mode also includes a planned schedule prediction mode, a low-indicator prediction mode, a medium-indicator prediction mode, or a high-indicator prediction mode. The low-indicator prediction mode refers to a mode that predicts the schedule under limited construction resources based on a preset prediction algorithm; the medium-indicator prediction mode refers to a mode that predicts the schedule under conventional construction resources based on the preset prediction algorithm; and the high-indicator prediction mode refers to a mode that predicts the schedule under high-standard construction resources based on the preset prediction algorithm.

[0057] Limited construction resources refer to construction under conditions of limited resources, such as restricting the number of construction workers and equipment, including reducing the number of workers and equipment by 20% or 30%. Conventional construction resources refer to the resources that the construction unit provides according to plan under normal circumstances, sufficient to meet the normal schedule requirements of the project. This includes a sufficient number of workers, including skilled and support staff, to meet the normal needs of the project, as well as sufficient equipment and tools in good condition to allow for planned construction. High-specification construction resources refer to resources that far exceed conventional needs under conditions of abundant resources. This includes a large number of skilled and support staff, multiple management and quality control personnel, the ability to work in shifts 24 hours a day, and advanced and sufficient construction equipment, with the option to add additional equipment as needed during construction.

[0058] Specifically, upon receiving a schedule projection instruction for the superstructure or the substructure, the method further includes: performing a schedule projection on the target bridge structure according to the schedule projection mode and the target bridge structure indicated by the schedule projection instruction, to obtain the target projected completion time for the target bridge structure; and determining a schedule warning for the target bridge structure based on the difference between the target projected completion time and the planned completion time for the target bridge structure.

[0059] Furthermore, in cases where the progress warning for special bridge structures (such as continuous beams) is delayed or severely delayed, to ensure construction progress and the smooth completion of the bridge, new projected completion times can be derived by employing low, medium, and high-indicator projection models. This allows for an assessment of whether the projected completion time can be advanced and whether the remaining time can be recovered. The projection results for each indicator also include the planned start date, planned completion date, projected completion date, and number of days of delay for the special bridge structure. In actual implementation, the projection results may also include detailed information such as whether there are conflicts with the next construction phase and the current construction stage.

[0060] Specifically, when the progress warning is delayed or severely delayed, after determining the progress warning for special bridge structures based on the differences between the projected completion time and the planned completion time, the girder erection vehicle's passage time, and the track laying time, the process also includes: re-projecting the construction period for the special bridge structures according to the low-index projection mode, the winning bid projection mode, and the high-index projection mode, respectively, to obtain the first projected completion time corresponding to the low-index projection mode, the second projected completion time corresponding to the winning bid projection mode, and the third projected completion time corresponding to the high-index projection mode; if there are some time points in the first, second, and third projected completion times that are earlier than the projected completion time, a prompt message is generated according to the projection mode corresponding to these time points that are earlier than the projected completion time. The prompt message is used to remind users to adjust the construction plan and construction resources according to the corresponding projection mode.

[0061] In practice, when performing progress simulations for special bridge structures, the simulation mode for the special bridge structure can be determined by receiving simulation instructions for the special bridge structure. This includes any one of the following modes: planned progress simulation mode, low-indicator simulation mode, medium-indicator simulation mode, or high-indicator simulation mode, in order to determine the simulation completion time.

[0062] Step S104: Color the bridge elevation drawing based on the progress warning and display the colored bridge elevation drawing on the progress warning interface. Different progress warnings correspond to different coloring colors.

[0063] By using progress alerts to color-code bridge elevation drawings and displaying the colored drawings on the progress alert interface, the progress status of different construction stages can be intuitively presented, allowing managers to clearly understand the difference between the actual and planned progress of the project. Different progress alerts correspond to different coloring colors, which can quickly identify which areas are behind schedule and which are progressing on schedule or ahead of schedule, helping to take timely corrective measures.

[0064] In some embodiments of this invention, visualization techniques are used to supplement and improve basic data and historical progress information to meet the requirements of refined bridge management, provide visual progress charts, project schedule simulations, progress warnings, and statistical information. This improves the intuitiveness and ease of use of progress and warning displays, reduces reliance on cumbersome textual or numerical analysis, and thus promotes efficient information transmission and decision-making. In this way, project managers can adjust resource allocation and strengthen management of key areas in a timely manner during actual construction, reducing the risk of project delays and ensuring the project progresses smoothly according to plan. Furthermore, the color-coded display of progress warnings provides effective support for subsequent project reviews and reports, facilitating overall progress monitoring and analysis, and improving the transparency and accuracy of project management.

[0065] In summary, the construction progress control method based on bridge elevation drawings provided in this application colors the bridge elevation drawings corresponding to the construction bridge based on the current progress information of the construction bridge, and displays the colored bridge elevation drawings on the progress display interface. The current progress information includes the construction status of each bridge structure on the construction bridge, with different coloring colors corresponding to different construction statuses. In the case of special bridge structures on the construction bridge, the construction period of the special bridge structures is extrapolated according to the planned progress extrapolation mode to obtain the extrapolated completion time of the special bridge structures. The planned progress extrapolation mode refers to the mode of predicting the progress based on a preset extrapolation algorithm combined with the original construction plan and construction resources. Based on the difference between the extrapolated completion time and the planned completion time, the girder erection vehicle passage time and the track laying time, a progress warning for the special bridge structures is determined. Based on the progress warning, the bridge elevation drawings are colored, and the colored bridge elevation drawings are displayed on the progress warning interface, with different coloring colors corresponding to different progress warnings. This method can solve the problem that existing progress management tools lack appropriate graphical display functions, intuitive charts and dashboards, tracking functions, and real-time monitoring capabilities. The previously poor data visualization made it difficult for users to keep track of project status and development trends. To address this, dynamic coloring of bridge elevations based on current construction progress information is used, displaying colors corresponding to different construction states to provide clear and intuitive progress visualization. For special bridge structures, a planned progress projection mode is employed. Based on the original construction plan and resources, the projected completion time of the special structure is predicted and compared with the planned completion time, girder erection vehicle passage time, and track laying time to generate progress warnings. These warnings are then displayed in color on the progress warning interface, helping users quickly identify project status and progress trends, improving the efficiency of progress tracking and real-time updates, and ensuring users can keep abreast of project progress. Furthermore, visualization methods supplement and improve basic data and historical progress information to meet the requirements of refined bridge management, providing visual progress charts, schedule projections, progress warnings, and statistical information. This enhances the intuitiveness and ease of use of progress and warning displays, reduces reliance on tedious text or numerical analysis, and promotes efficient information transmission and decision-making.

[0066] The following is an introduction to the construction progress control system based on bridge elevation drawings provided in this application, such as... Figure 2 As shown. The system includes: an information maintenance module 210, a schedule prediction module 220, and a progress early warning module 230.

[0067] In some embodiments of the present invention, the information maintenance module 210 is used to color the bridge elevation drawing corresponding to the construction bridge based on the current progress information of the construction bridge, and display the colored bridge elevation drawing on the progress display interface.

[0068] The current progress information includes the construction status of each bridge structure on the construction bridge, with different colors corresponding to different construction statuses.

[0069] In some embodiments of the present invention, the basic data and current progress information of the construction bridge are obtained from the Railway Engineering Management Platform (REMPLAT). The basic data includes project information, contract information, bridge information, and work site information corresponding to the construction bridge, which is automatically obtained from the basic data platform of the Railway Engineering Management Platform; the current progress information is obtained from the electronic construction log management system of the Railway Engineering Management Platform.

[0070] In some embodiments of the present invention, the basic data is used for information maintenance and construction task creation and editing of the various entities corresponding to the construction bridge in the system. The information maintenance of the construction bridge includes the maintenance of information on the superstructure, the superstructure itself, and special bridge structures. The various entities corresponding to the construction bridge are obtained through engineering breakdown structure.

[0071] For the substructure of the bridge, such as Figure 3 As shown, by selecting the section to be edited under the directory tree structure, and then selecting the substructure option of the target construction bridge, you can see three columns of content: the bridge piers, the pier body, the foundation and substructure, and the pile foundation. The pier information includes information such as pier number, center mileage, design weight, and type; the pier body, foundation and substructure, and pile foundation include information such as name, height, width, and total design quantity.

[0072] In practice, the construction information of each substructure of the bridge can be maintained and supplemented with information such as structure name, total design quantity and pier type by using the drawings of the designer or other data sources.

[0073] For the superstructure of the bridge, such as Figure 4 As shown, the maintenance of the superbridge structure mainly involves the span type. By clicking the "Add" button, information on the superbridge structure, such as the number of spans, span, beam type, construction type, area spanned, length, start and end piers, and special structural lines, can be improved.

[0074] After maintaining the information about the superstructure of the bridge, such as Figure 5 and Figure 6As shown, clicking the "Maintain Special Structure" button allows you to maintain the elevation information of special bridge structures. After selecting a specific special bridge structure, you can maintain different components within that structure in the corresponding information list. For example, you can fill in the names of segments such as the T-section, side span, straight segment, and mid-span of a rigid prestressed concrete continuous beam, as well as construction information such as the maximum number of T-sections, and the width and height of the side span, straight segment, and mid-span.

[0075] After maintaining all the information about the bridge structure, construction tasks can be created and edited. When editing construction tasks, it is necessary to first set up a new construction task and then edit the corresponding schedule to ensure the accuracy of the schedule.

[0076] like Figure 7 As shown, firstly, the planning interface is displayed by activating the planning button. Within the directory tree structure of the planning interface, select the bridge within the target section for which you want to create a planned schedule, and then perform the following operations: create a new plan version, edit the plan, set the girder erection vehicle's passage time, and set the track laying date. The track laying date can be obtained from the track laying dates for the entire line. After the plan is completed, lock it; subsequent schedule warnings are based on the locked construction plan version.

[0077] When creating a new construction task, clicking the control that edits the detailed plan will take you to the detailed plan interface for that task. The left side of the detailed plan interface includes a list of construction task information, such as... Figure 8 As shown, this is used to display information such as the created prerequisite tasks, duration, start date, and end date. Additionally, as... Figure 9 As shown, the right side of the detailed plan interface also includes a Gantt chart that matches each construction task.

[0078] In some embodiments of the present invention, the current progress information is maintained and entered through the information maintenance module 210. After receiving a click operation on the progress entry button under the information maintenance module 210, a list of bridges under construction is displayed. The target bridge is identified in the list of bridges under construction, and the upper and lower bridge structures are selected respectively to enter the current progress information, including the construction status and time of each bridge structure. The construction status includes: not under construction, under construction, and completed.

[0079] When filling in the progress report for the superstructure of the bridge, such as Figure 10 As shown, the beam yard number, completion status, actual erection date, and planned erection date for this structure can be maintained. When reporting the progress of the substructure, as shown... Figure 11 As shown, the system allows maintenance of a specific list of pier bodies, foundations, and pile foundations for a particular pier, including their construction status and date information.

[0080] After the current progress information maintenance is completed, the progress display interface will be shown, such as... Figure 12 As shown, the progress display interface includes a bridge elevation view. This elevation view presents the layout of the superstructure and substructure (or special structures) of the bridge under construction in a two-dimensional plan view, including the starting and ending points, pier numbers, pile arrangement, and construction or completion time. In this elevation view, different colors are used to indicate whether the bridge is under construction, not under construction, or not under construction, visually displaying the construction status of the bridge. Meanwhile, to facilitate users' real-time viewing of bridge structure information and related construction progress, when viewing bridge elevation drawings, users can click on a specific bridge structure's elevation drawing using a mouse or touchscreen, or hover the mouse pointer over it to trigger a pop-up window displaying detailed information and current construction progress. This ensures real-time accuracy and helps users quickly understand the construction progress and timelines for each bridge structure. For example, taking a completed pier as an example, the pop-up window includes the bridge structure's name, actual start date, actual completion date, pier width, and pier height.

[0081] In addition, the progress display interface also includes zoom in controls, zoom out controls, and bridge pier number query controls, which are used to zoom in and out of the bridge elevation view and to facilitate project managers to view detailed information of the work site and query the location of the bridge piers; specifically, when a zoom-in operation is received on the zoom-in control, the bridge elevation view displayed in the progress display interface is zoomed in according to the preset zoom ratio.

[0082] Upon receiving a zoom-out operation applied to the zoom-out control, the bridge elevation view displayed on the interface is zoomed out according to the preset zoom-out ratio; the target pier number is selected by using the pier number query checkbox in the bridge pier number query control, and upon receiving a query operation applied to the query button, the pier indicated by the target pier number is located.

[0083] After the current progress information is maintained, the schedule of special bridge structures in the construction bridge is simulated using the schedule simulation module 220.

[0084] In some embodiments of the present invention, the construction period of special bridge structures is simulated according to a planned schedule simulation model to obtain the simulated completion time of the special bridge structures. The planned schedule simulation model refers to a model that predicts the progress based on a preset simulation algorithm combined with the original construction plan and construction resources. The original construction plan includes the original construction start date and construction end date; the original resources include human resources, equipment resources, or material resources, etc.

[0085] Specifically, the schedule prediction module 320 is used to predict the schedule of special bridge structures in the case of special bridge structures on the construction bridge according to the planned schedule prediction mode, so as to obtain the predicted completion time of the special bridge structure. The planned schedule prediction mode refers to the mode of predicting the progress based on the preset prediction algorithm combined with the original construction plan and construction resources.

[0086] In practice, other simulation modes can also be used to simulate the construction period of special bridge structures, including planned schedule simulation modes, low-indicator simulation modes, medium-indicator simulation modes, or high-indicator simulation modes. The low-indicator simulation mode predicts the schedule based on a preset simulation algorithm under limited construction resources; the medium-indicator simulation mode predicts the schedule based on the preset simulation algorithm under conventional construction resources; and the high-indicator simulation mode predicts the schedule based on a preset simulation algorithm under high-standard construction resources.

[0087] Furthermore, in cases where the progress warning for special bridge structures (such as continuous beams) is delayed or severely delayed, to ensure construction progress and the smooth completion of the bridge, new projected completion times can be derived by employing low, medium, and high-indicator projection models. This allows for an assessment of whether the projected completion time can be advanced and whether the remaining time can be recovered. The projection results for each indicator also include the planned start date, planned completion date, projected completion date, and number of days of delay for the special bridge structure. In actual implementation, the projection results may also include detailed information such as whether there are conflicts with the next construction phase and the current construction stage.

[0088] After completing the simulation of the special bridge structure, the progress warning module 230 determines the progress warning of the special bridge structure based on the difference between the simulated completion time and the planned completion time, the girder erection vehicle passage time and the track laying time. The bridge elevation drawing is colored based on the progress warning and displayed on the progress warning interface. Different progress warnings correspond to different coloring colors.

[0089] Specifically, based on the differences between the projected completion time and the planned completion time, the girder erection vehicle's transit time, and the track laying time, the progress warning for special bridge structures should include at least the following situations: The first scenario is that if the projected completion time does not exceed the planned completion time, the progress warning is considered normal.

[0090] The second scenario is that if the projected completion time exceeds the planned completion time, and the first time difference between the projected completion time and the girder erection vehicle's transit time is greater than or equal to 28 days, the progress warning is considered delayed.

[0091] If the time difference is less than 28 days, the progress warning indicates a serious delay.

[0092] The third scenario is that if the girder erecting vehicle fails to pass through a special bridge structure, the projected completion time exceeds the planned completion time, and the second time difference between the projected completion time and the track laying time is greater than or equal to 28 days, the progress warning is delayed.

[0093] If the second time difference is less than 28 days, the progress warning indicates a serious lag.

[0094] In some embodiments of the present invention, after selecting any section under the target tree structure, a bridge statistics interface is displayed, including a bridge construction progress statistics chart and a bridge construction progress statistics table. The bridge construction progress statistics chart uses bar charts and pie charts to statistically analyze the construction progress, special structure progress warning ratio, and construction status of all bridge components under that section, including pile foundations, abutments, piers, open-cut sections, and spread foundations.

[0095] refer to Figure 13 To more intuitively display the progress warning proportions for various special bridge structures, the progress warnings for each special bridge structure were visualized, resulting in a pie chart showing the proportion of each type of progress warning. The pie chart visually displays the percentage of each type of progress warning through the size and proportion of the sectors. Each sector represents a progress status (e.g., "Normal," "Lagging," "Severely Lagging"), allowing project managers to quickly understand the overall progress distribution and clearly see which parts of the progress are experiencing problems and the severity of those problems. (Reference) Figure 14 The project progress and key indicators are displayed visually in the form of tables, including information such as the completion progress of each bridge structure yesterday, the completion progress this month, and the cumulative completion progress for the year.

[0096] Based on this, such as Figure 2 As shown, in some embodiments of the present invention, the system further includes a progress statistics module 240, which is used to draw a construction status statistics chart and a construction status statistics table based on progress warnings and current progress information; the construction status statistics chart includes a bar chart and a pie chart, the bar chart and the construction status statistics table are used to display the construction progress of each bridge structure, and the pie chart is used to display the progress warning ratio of special bridge structures; the construction status statistics chart and the construction status statistics table are displayed on the bridge statistics interface.

[0097] In summary, the bridge elevation-based construction progress control system provided in this application addresses the shortcomings of existing progress management tools, such as a lack of appropriate graphical display functions, intuitive charts and dashboards, poor tracking capabilities, and inadequate real-time data visualization, which can make it difficult for users to grasp the project's status and development trends in a timely manner. By dynamically coloring the bridge elevation based on the current construction progress information, different colors corresponding to different construction states are displayed, providing a clear and intuitive progress visualization effect. When encountering special bridge structures, a planned progress extrapolation mode is adopted, predicting the completion time of special structures based on the original construction plan and resource allocation, and comparing it with the planned progress. By comparing the completion time, the girder erection vehicle's transit time, and the track laying time, progress warnings are generated. These warnings are then displayed in color on the progress warning interface, helping users quickly identify project status and progress trends, improving the efficiency of progress tracking and real-time updates, and ensuring users can keep abreast of project progress. Simultaneously, visualization methods supplement and improve basic data and historical progress information to meet the requirements of refined bridge management, providing visual progress charts, schedule projections, progress warning reminders, and statistical information. This enhances the intuitiveness and ease of use of progress and warning displays, reduces reliance on tedious text or numerical analysis, and thus promotes efficient information transmission and decision-making.
