[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0038] Example 1

[0039] like Figure 1 As shown in Example 1, this embodiment provides a method for scheduling the overall construction schedule of a pumped storage power station. The specific steps are as follows:

[0040] S1. Construct a template library for the overall construction schedule; wherein, the template library includes node projects and individual projects; each individual project includes several individual buildings and the logical relationships between them; the logical relationships between individual buildings include the logical relationships between individual buildings within the same individual project and the logical relationships between individual buildings across different individual projects; the construction process of the template library specifically includes:

[0041] A1. Collect data on individual projects; wherein, the data on individual projects includes basic data; the basic data includes project location and quantity; the quantity includes calculated quantity and characteristic quantity of construction procedures; the calculated quantity is the physical quantity of the project during construction; the characteristic quantity is the geometric characteristic parameter characterizing the structure and construction scale of the individual project;

[0042] A2. Construct the logical relationships between the construction procedures and between the individual buildings; based on the construction period quota, obtain the construction progress indicators of the construction procedures, the construction progress indicators including construction intensity; wherein, the individual buildings are decomposed into multiple construction procedures according to the construction process;

[0043] A3. Based on the construction period of the construction process, the logical relationship between the construction processes, and the logical relationship between the individual buildings, the construction progress of the individual project is obtained; wherein, the construction period of the construction process = the characteristic engineering quantity of the construction process. The construction intensity of the construction process is determined based on the construction period quota. Since the progress indicators and construction intensity in the construction period quota are based on characteristic quantities, characteristic quantities are added to the template library to make the construction period calculation more intuitive and convenient.

[0044] In this embodiment 1, the node project includes project commencement, preparatory project, preparatory project, commencement of main project, reservoir closure, reservoir gate closure, commissioning of the first generating unit, and project completion.

[0045] The calculated engineering quantities include excavation volume, filling volume, and concrete pouring volume; the characteristic engineering quantities include slope excavation height, tunnel length, dam filling height, and panel concrete area.

[0046] In this embodiment 1, the logical relationships include: a first relationship, a second relationship, a third relationship, and a fourth relationship;

[0047] The first relationship is that a subsequent process can only begin after the preceding process has been completed;

[0048] The second relationship is that the completion of a subsequent process depends on the completion of the preceding process;

[0049] The third relationship is that the start of a subsequent process depends on the start of the preceding process;

[0050] The fourth relationship is that a subsequent process can only be completed when the preceding process has started.

[0051] S2. Based on the template library, select the individual projects and individual buildings involved in the actual project;

[0052] In this embodiment 1, if the individual project and / or individual building involved in the actual project is not recorded in the template library, then the unrecorded individual project and / or individual building is added to the template library. The individual building can be a single-level directory structure, a two-level directory structure, or a multi-level directory structure.

[0053] S3. Preset the reservoir closure time and reservoir gate closing time in the node project corresponding to the actual project;

[0054] S4. Based on the node projects corresponding to the actual project, establish the logical relationship between the individual buildings involved in the actual project to obtain the overall construction schedule of the actual project;

[0055] S5. Update the overall construction schedule of the actual project until the overall project schedule target of the actual project is met;

[0056] Update the overall construction schedule of the actual project, specifically including: adjusting the construction schedule of individual projects of the actual project or the reservoir closure time and reservoir gate closing time of the corresponding node projects of the actual project.

[0057] S6. Based on the overall construction schedule obtained in step S5, generate a construction schedule Gantt chart, a construction intensity statistics table, a project quantity summary table, and parameter charts.

[0058] In existing technologies, the strength data corresponding to some engineering quantities needs to be obtained by manually selecting the corresponding buildings and performing cumulative calculations after exporting all strength data. In the pumped storage power station construction schedule planning method provided in Embodiment 1, after the overall construction schedule is completed, it allows for the selection of some or all buildings, and then the engineering quantities of the selected buildings are automatically calculated to generate strength data charts, specifically including monthly and annual strength tables. For example, to obtain the construction intensity of the open excavation of the upper reservoir, only the upper reservoir needs to be selected for the single building, and the construction process needs to be selected as open excavation. The output strength data includes monthly and annual construction intensities for open excavation, earthwork filling, rock excavation, and concrete construction. Corresponding strength curves are generated based on the construction intensity statistics table.

[0059] The method for compiling the overall construction schedule of a pumped storage power station provided in Example 1, based on relevant regulations and standards, enables the creation of a template library, improves the initial scheduling efficiency of the overall construction schedule of conventional pumped storage structures, and allows users to easily and quickly modify and optimize the schedule according to project characteristics.

[0060] Example 2

[0061] Figure 2 This document presents a flowchart for designing a template library for the overall construction schedule of a pumped storage power station. The following section combines... Figure 2 The design process of the construction schedule template library in Example 2 is explained below. The specific steps are as follows:

[0062] Step A01: Collect basic data of individual buildings to obtain individual project data; the basic data includes project location and project quantity.

[0063] A single building is an important component of a construction project, possessing independent construction conditions and complete functionalities. It serves as the basic unit for construction units to prepare construction organization plans and organize construction. In this embodiment 2, a single building includes several individual buildings; each individual building can be decomposed into multiple construction procedures according to the construction process. Each construction procedure, as the smallest work unit, has a quantity attribute, which includes calculated quantities and characteristic quantities. Calculated quantities are the physical quantities of the single building during construction; characteristic quantities are geometric feature parameters that characterize the structure and construction scale of the single building.

[0064] Based on the engineering components of a pumped storage power station, a single building can be a single-level, two-level, or multi-level structure. The corresponding construction procedures include open excavation, tunnel excavation, earthwork filling, and concrete pouring. Calculated quantities include, but are not limited to, excavation volume, filling volume, and concrete pouring volume, all in cubic meters. Characteristic quantities include, but are not limited to, slope excavation height, tunnel length, dam filling height, and concrete panel area, all in meters or square meters. Compared to existing technologies, the basic data collected for a single building in this embodiment 2 is more comprehensive.

[0065] Step A02: Construct a single project schedule library.

[0066] In the individual project schedule database, corresponding schedule database data is configured for each individual project, including the logical relationships between construction procedures, the construction progress indicators of construction procedures, and the logical relationships between individual buildings.

[0067] Based on the construction procedures and technologies of individual buildings, logical relationships are established between construction processes, between individual buildings, and process delays. The definition of logical relationships includes the following four types:

[0068] ① Finish-Start (FS): A subsequent process can only begin after the preceding process has been completed.

[0069] ② Finish-Finish (FF): The completion of a subsequent process depends on the completion of the preceding process;

[0070] ③ Start-Start (SS): The start of a subsequent process depends on the start of the preceding process;

[0071] ④ Start-Finish (SF): A subsequent process can only be completed when the preceding process has started.

[0072] The construction procedures for individual buildings can be obtained from regulations and standards such as the "Design Code for Pumped Storage Power Stations", "Construction Period Quota for Hydropower (including Pumped Storage EPC) Projects" and "Guidelines for the Compilation of Overall Construction Schedule for Pumped Storage Power Station Projects".

[0073] Based on the construction period quota, the construction progress indicators of the construction process are obtained, and the construction progress indicators are matched with the characteristic engineering quantities of the corresponding individual buildings to determine the construction period and construction progress of the individual buildings and corresponding individual projects; the construction of the individual project progress database is completed; among them, the construction period quota refers to the standard construction time specified by the standard for completing the corresponding engineering content, construction process or engineering quantity, and is the basis for calculating the construction period; the construction progress indicators refer to the quantitative indicators used to reflect the construction progress status of the project, including but not limited to the planned start time, planned end time, construction period, construction intensity, etc.

[0074] The construction technology of pumped storage power stations includes civil engineering and electromechanical installation. Civil engineering includes open-cut construction, tunnel excavation, anchor spraying support, dam filling, concrete pouring, and steel pipe installation. Electromechanical installation includes primary electrical systems, secondary electrical systems, and mechanical systems, including transformer installation, secondary cable installation, and pump and turbine installation.

[0075] Step A03: Obtain the construction progress of the individual project.

[0076] The individual project data and the individual project schedule database are preprocessed separately. The preprocessing includes data filtering and editing to ensure the accuracy of the project quantities.

[0077] Divide the characteristic engineering quantity corresponding to the construction process by the construction intensity to obtain the construction period of the construction process. Combine the logical relationship between the construction processes and the logical relationship between individual buildings to obtain the construction progress of the individual project.

[0078] Based on the common individual structures of pumped storage power stations, the above steps can be used to establish a template library for the overall construction schedule of pumped storage power stations.

[0079] Example 3

[0080] like Figure 3 As shown in Example 3, this embodiment provides a method for scheduling the overall construction schedule of a new pumped storage power station project. The specific steps are as follows:

[0081] Step 1: Create a new project using the template library.

[0082] Based on the template library of the overall construction schedule for pumped storage power stations provided in Example 2, select the individual projects and individual buildings involved in the actual new construction project.

[0083] Step 2: Set the logical relationships between individual buildings in the actual new project according to the node project settings.

[0084] Nodes are used to control construction progress and represent key milestone targets. Node projects are engineering contents within the project schedule that represent key milestones and control the construction period, used to identify important control objectives during project implementation. For pumped storage power station projects, node projects include project commencement, preparatory work, preparatory work, commencement of main construction, upper reservoir closure, lower reservoir closure, upper reservoir gate closure, lower reservoir gate closure, commissioning of the first generating unit, and project completion. Based on the project's planned commencement and completion dates, the planned duration of preparatory work, the planned duration of preparatory work, and information on individual buildings, the closure and gate closure times are preset. The node requirement for the overall project schedule target is the commissioning time of the first generating unit. The closure time includes the closure time of the upper and lower reservoirs of the pumped storage power station, and the gate closure time includes the gate closure time of the upper and lower reservoirs.

[0085] Step 3: The construction progress of each individual project is linked to the actual milestone targets of the new project. For example, if a milestone target has a logical relationship with both individual project A and individual project B, the relationship between individual project A and individual project B is indirectly established by linking this milestone target with individual project A and individual project B using any of the four logical relationships provided in Example 2. By linking multiple individual projects sequentially, the overall construction schedule plan for the project can be formed and obtained.

[0086] Through intelligent calculation of the critical path schedule, the initial overall construction schedule for the actual new project is obtained. The critical path is the path with the longest total work duration in the entire project; the critical path schedule refers to the project schedule corresponding to the critical path in the project plan, and its changes directly affect the overall project duration.

[0087] The overall project schedule target is the overall project schedule control target, and the milestone targets are the phased milestone targets obtained by decomposing the overall project schedule target. The achievement of several milestone targets together support the achievement of the overall project schedule target.

[0088] Step 4: Automatically generate a construction schedule Gantt chart based on the actual construction schedule data of the new project. Adjust the construction schedule of individual projects or the construction intensity of individual operations according to the critical path and free float, so that the overall construction schedule changes. Iteratively update the calculation until a construction schedule that meets the overall project schedule target is generated.

[0089] Specifically, after intelligent calculation, if the critical path and nodes meet the overall project schedule target, then step 5 is executed; if any critical path or node does not meet the requirements, then the construction schedule of the individual project is adjusted; if the node does not meet the requirements, but the logical relationship in the construction schedule of the individual project is correct and the schedule indicators have been adjusted to the optimal, then the node target is adjusted, for example, adjusting the reservoir closure time and reservoir gate closing time in the node project corresponding to the actual new project.

[0090] Step 5: Based on the latest Gantt chart of the overall construction schedule after iteration, the main quantities of some or all individual buildings can be output as needed. A bar chart of quantities and a strength data table can be generated according to the schedule time, showing the strength data by year and month, the total amount, etc., which provides convenience for subsequent work such as earthwork balance and concrete aggregate calculation.

[0091] When creating an actual project, for individual buildings that are missing from the template library, you can add the following information: project name, planned start time, planned end time, quantity, duration, logical relationships, etc., to complete and arrange the missing individual buildings and update them to the template library.

[0092] If the overall construction schedule for Project A has already been completed, and Project B contains the same individual structures as Project A—for example, both projects have concrete-faced dams for both upper and lower reservoirs and two-stage vertical shafts for their water conveyance systems, differing only in dam height and shaft depth—then the source files for Project A can be used to import the updated bill of quantities for Project B, generating the initial overall construction schedule for Project B with a single click. The source files for Project A include individual project data, an individual project schedule library, and individual project construction schedules.
