DETAILED DESCRIPTION

[0030] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1As shown, a system for preparing a visual construction schedule for a hydropower project includes a BIM model management module 1, a construction process management module 2, a BIM model segmentation management module 3, a construction schedule visualization preparation module 4, a construction process verification module 5, a construction resource analysis module 6, a construction schedule optimization module 7, and a construction schedule visualization display module 8:

[0032] BIM model management module 1 is used to import BIM models, implement the update and replacement of single BIM model files, the overall replacement of model files after assembly and integration, and the management of BIM model file versions;

[0033] Construction process management module 2 is used to manage and divide the construction process of hydropower projects, and can divide the process by area or system;

[0034] BIM model segmentation management module 3, used to automatically segment the BIM model and associate corresponding processes according to the division of construction processes;

[0035] The construction schedule visualization module 4 is used to visualize the construction schedule. It assigns a start time, duration, and end time to each construction process, and logically sets the relationship between construction processes. At the same time, it assigns the required personnel and construction machinery inputs to each construction process based on the engineering quantity extracted from the BIM model.

[0036] Construction process verification module 5 is used to verify the construction process. It combines the prepared construction schedule with the BIM model to check the integrity of construction tasks and data assignments to ensure that there are no omissions in the entire hydropower project construction process and the corresponding data are complete;

[0037] Construction resource analysis module 6 is used to conduct preliminary analysis based on the duration of the construction process and provide an allocation analysis of the construction personnel and construction machinery for the corresponding process;

[0038] Construction schedule optimization module 7 is used to verify and modify the logical relationship of construction processes;

[0041] The construction process division format in the construction process management module 2 includes: serial number, construction process name, and grid coordinates.

[0042] The construction process verification module 5 automatically calculates and selects BIM models that correspond to the construction process and are assigned time, logical relationships and resources. The BIM model that contains all elements is displayed in green highlight mode, the BIM model that does not correspond to the construction process is highlighted in red, and the BIM model that corresponds to the construction process but lacks time or logical relationships or resource assignments is highlighted in yellow.

[0043] The construction schedule optimization module 7 realizes the automatic display of the construction schedule in chronological order through the time-driven BIM model, and then observes whether the logical relationship between the construction processes is reasonable. If it is unreasonable, it is optimized, modified and adjusted in the construction schedule visualization compilation module 4.

[0044] The construction progress plan visualization display module 8 displays the BIM model in the upper half and the construction progress plan arrangement and bar chart in the lower half. At the same time, it can be filtered according to different dimensions such as time, space and system to achieve a visual display of the construction progress plan.

[0045] A method for compiling a visual construction schedule for a hydropower project is provided. The method is based on the aforementioned visual construction schedule compilation system for a hydropower project and is as follows:

[0046] After dividing the hydropower project process, the BIM model is automatically segmented to achieve a one-to-one correspondence between the process and the BIM model. Then, the construction resources, time, and logical relationships are matched with the BIM model. Combined with the BIM model, the compiled construction schedule is used to verify the process and analyze the resources. The unreasonable construction process and resource arrangements are visually optimized, and finally the construction schedule is visualized based on the BIM model, completing the visual compilation of the construction schedule.

[0047] Specifically, the above-mentioned method for compiling a visual construction schedule for a hydropower project is implemented in the following manner:

[0048] First, import the BIM model through the BIM model management module 1. The BIM model should include all elements of the hydropower project construction scope, such as construction machinery, temporary construction facilities and permanent facilities. The format of the BIM model is the common .dgn and .rvt formats. The BIM model management module 1 can realize the update and replacement of a single BIM model file, and can also realize the overall replacement of the model file after assembly integration, and realize the management of BIM model file versions, such as version A, version B, version C, etc. The construction process management module 2 realizes the management and compilation of the hydropower project construction process. The process can be divided according to the area or system. For example, the installation of the volute layer technical water supply system equipment and pipelines of the No. 1 unit in the main powerhouse. The spatial range grid coordinates corresponding to this process are 0+000m and 0+25.0m on the left of the plant, 0+000m above the plant and 0+22.0m below the plant. The elevation of the volute layer technical water supply system equipment and pipelines is EL.80.0m~EL.86.0m. The compilation format of its construction process division is as follows: Figure 2 shown.

[0049] The process management function of the construction process management module 2 realizes basic functions such as process merging, splitting, adding and deleting. The BIM model segmentation management module 3 automatically segments the BIM model according to the construction process division of the construction process management module 2, specifically: Figure 3As shown, the spatial grid coordinates of the construction process division in the construction process management module 2 are used to automatically read the grid surface coordinates of the corresponding process from the BIM model and set them as cutting surfaces. The BIM model is automatically cut according to the cutting surfaces and the corresponding processes are associated. For example, for the installation of the technical water supply system equipment and pipelines of the volute layer of the main powerhouse unit 1, the spatial range grid coordinates corresponding to this process are 0+000m (surface 1) and 0+25.0m (surface 2) on the left side of the plant, 0+000m (surface 10) above the plant, and 0+22.0m (surface 9) below the plant. The elevation of the volute layer technical water supply system equipment and pipelines is EL.80.0m (surface 6) to EL.86.0m (surface 7). The grid surface coordinates are automatically read directly from the BIM model using the above coordinates and a cutting surface is formed. After completion, the BIM model is automatically cut to form a BIM model of the corresponding process. When there are grid coordinate changes such as merging, deleting, and adding processes in the construction process management module 2, the BIM model segmentation management module 3 can automatically adjust the segmentation grid surface according to the adjusted construction process. After the BIM model is segmented according to all the processes in the construction process management module 2, the construction schedule visualization compilation module 4 performs visualization compilation of the construction schedule, assigns a start time, duration, and end time to each construction process, and logically sets the relationship between the construction processes. At the same time, combined with the engineering quantity extracted from the BIM model, the required personnel input and construction machinery input are assigned to the construction process. By repeating the above steps for each construction process until all construction processes are completed, the compilation of the construction schedule for the entire hydropower project is completed. After the entire construction schedule is compiled, the construction processes are verified using the Construction Process Verification Module 5. This module automatically calculates and selects BIM models that correspond to construction processes and have been assigned time, precedence, and succession relationships, as well as resources. BIM models that include all elements are highlighted green, while BIM models without corresponding construction processes are highlighted red. BIM models that correspond to construction processes but lack time, precedence, and succession relationships, or resource assignments, are highlighted yellow. For BIM models with red highlights that do not correspond to construction processes, the Construction Process Management Module 2 verifies whether any construction processes are missing. If so, construction processes are added. The BIM Model Segmentation Management Module 3 then segments the model and associates the construction processes. Once completed, the Construction Process Visualization Compilation Module 4 assigns start times, durations, and end times to the construction processes. The precedence and succession relationships are logically defined, and the required personnel and machinery inputs are assigned. For BIM models highlighted yellow, the Construction Process Visualization Compilation Module 4 adds time, precedence, and succession relationships, or resource assignments. Repeat the above steps until the construction schedule is completed.After the construction schedule is verified, it is necessary to analyze and verify whether the arrangement of construction resources for each process is scientific and reasonable. The construction resource analysis module 6 can conduct a preliminary analysis based on the engineering quantity directly extracted from the BIM model, combined with the duration of the construction process, and provide an allocation analysis of the construction personnel and construction machinery for the corresponding process. The logical relationship of the construction process is verified and modified through the construction schedule optimization module 7. This module realizes the automatic display of the construction schedule in chronological order through the time-driven BIM model, and then observes whether the logical relationship between the construction processes is reasonable. If it is unreasonable, it is optimized, modified and adjusted in the construction schedule visualization compilation module 4. Finally, the compiled construction schedule can be fully displayed in the construction schedule visualization display module 8, as shown. Figure 4 As shown, the display is divided into the BIM model in the upper part and the construction schedule and bar chart in the lower part. It can also be filtered according to different dimensions such as time, space and system to achieve a visual display of the construction schedule.
