Description

Technical Field

[0001] The present invention relates to the technical field of urban rainwater pipe network reconstruction, and in particular to an urban rainwater pipe network reconstruction planning method, device, equipment and storage medium. Background Art

[0002] The renovation of urban rainwater pipe networks is the core link in the construction of rainwater and sewage diversion systems during the process of urban combined rainwater and sewage transformation and rainwater diversion. The renovation of urban rainwater pipe networks (especially the transformation of combined rainwater and sewage pipe networks in old urban areas into rainwater and sewage diversion pipe networks) aims to build an independent rainwater collection and transportation system. Through replacement, repair or new construction and access and other renovation methods, it realizes the separate collection, efficient transportation, safe discharge and resource utilization of rainwater, improves the urban water environment, and enhances drainage and flood prevention capabilities. It plays an irreplaceable role in ensuring urban ecological security and sustainable development.

[0003] In actual construction scenarios, the renovation of the rainwater pipe network in the old city is based on the requirements of first the source and then the end (following the principle of topological convergence logic + pollution prevention and control needs), first the main line and then the branch line (following the principle of priority of drainage channels + avoiding the risk of waterlogging). After completing the preliminary investigation and design work, it is necessary to gradually renovate the multiple pipe network nodes to be renovated under the original pipe network. The planning of this renovation process is restricted by many factors: first, the project construction content of different renovation locations is different, and the project construction time and resources required for project construction are different; second, each renovation location has a different topological position in the regional pipe network topology relationship diagram, and different topological positions have construction execution requirements. The impact of the order of precedence; thirdly, because the construction of rainwater pipe network renovation projects is affected by rainfall, different renovation projects cannot be constructed normally when they are disturbed by different rainfall amounts. The topological connection relationship between the main pipe network, branch lines and source means that the rainfall amount of each renovation project usually takes into account not only the rainfall at its own location, but also the superimposed impact of its associated pipe network source within the topological connection relationship (for example, if the rainfall in any branch line or source area exceeds the standard, rainwater will flow back into the main pipe foundation pit through the pipe network). In addition, for the sake of construction safety, regardless of the renovation method used, it is necessary to ensure that the superimposed parameters of the pipe network rainfall at the location of each renovation project do not exceed the specified construction threshold. The combined existence of these limitations makes the execution and planning of pipe network renovation tasks extremely difficult, increases the overall construction difficulty, and reduces construction efficiency and safety.

[0004] Therefore, how to reasonably and scientifically plan the execution sequence and execution period of each renovation project in the pipeline renovation task in the target pipeline renovation area, on the basis of improving the construction efficiency of urban pipeline renovation tasks, meet the construction sequence requirements of the rainwater pipeline renovation location and the construction safety of the topological superimposed rainfall restriction conditions, and shorten the construction period and reduce construction costs as much as possible, is a technical problem that needs to be solved urgently.

When the construction of each reconstruction project is completed, the pipe network reconstruction planning strategy is updated based on the re-acquired rainfall prediction information, the construction plan completion time of the reconstruction projects under construction, and the pipe network reconstruction planning influence feature set of the remaining reconstruction projects.

[0025] The specific embodiments of the application applied to the device are basically the same as the various embodiments of the application of the urban rainwater pipe network reconstruction planning method described below, and will not be repeated here.

[0026] The embodiment of the application provides a kind of urban rainwater pipe network reconstruction planning method, refer to Figure 2 , Figure 2 It is the flowchart of the embodiment of the application of the urban rainwater pipe network reconstruction planning method.

[0027] In this embodiment, a kind of urban rainwater pipe network reconstruction planning method, comprising the following steps: S100: obtain the pipe network reconstruction task of target pipe network reconstruction region;Wherein, the pipe network reconstruction task includes the reconstruction project associated information of several reconstruction sub-regions; S200: extract the project attribute information of several reconstruction projects in the reconstruction project associated information of each reconstruction sub-region, according to the project construction content and project construction topological relationship position in the project attribute information, the pipe network reconstruction planning influence feature set of each reconstruction project under the pipe network reconstruction task is constructed; S300: obtain the rainfall prediction information and pipe network reconstruction resource configuration information of target pipe network reconstruction region in reconstruction planning period, consider the project construction time length feature and project construction resource demand feature about project construction content in pipe network reconstruction planning influence feature set and the project construction sequence feature about project construction topological relationship position, utilize the optimization model based on multiple constraint conditions, solve pipe network reconstruction planning strategy; S400: according to the project construction plan of each reconstruction project under each reconstruction sub-region in the pipe network reconstruction planning strategy, the pipe network reconstruction project construction of each reconstruction project is performed; S500: when the construction of each reconstruction project is completed, the pipe network reconstruction planning strategy is updated based on the re-acquired rainfall prediction information, the construction plan completion time of the reconstruction projects under construction and the pipe network reconstruction planning influence feature set of the remaining reconstruction projects.

[0028] It should be noted that, in actual construction scenarios, the renovation of the rainwater pipe network in the old city is based on the requirements of first the source and then the end (following the principle of topological convergence logic + pollution prevention and control needs), first the main line and then the branch line (following the principle of priority of drainage channels + avoiding the risk of waterlogging). After completing the preliminary investigation and design work, it is necessary to gradually renovate the multiple pipe network nodes to be renovated under the original pipe network. The planning of this renovation process is restricted by many factors: first, the project construction content of different renovation locations is different, and the project construction time and resources required for project construction are different; second, each renovation location has a different topological position in the regional pipe network topology relationship diagram, and different topological positions have construction difficulties. First, the order in which projects are executed is affected. Second, because the construction of stormwater pipe network renovation projects is affected by rainfall, different renovation projects cannot proceed normally when they are disturbed by different rainfall amounts. The topological connection between the main and branch pipe networks and their sources means that the rainfall amount for each renovation project usually takes into account not only the rainfall at its own location, but also the superimposed impact of its associated pipe network sources within the topological connection (for example, if rainfall in any branch line or source area exceeds the standard, rainwater will flow back into the main pipe network foundation pit through the pipe network). Furthermore, for construction safety considerations, regardless of the renovation method used, it is necessary to ensure that the superimposed parameters of the pipe network rainfall at the location of each renovation project do not exceed the specified construction threshold. The combined existence of these limitations makes the execution and planning of pipe network renovation tasks extremely difficult, increasing the overall construction difficulty and reducing construction efficiency and safety.

[0029] In this embodiment, by obtaining pipeline network renovation tasks, extracting the project construction content and project construction topological relationship locations of several renovation projects in each renovation sub-area, and then obtaining rainfall forecast information and pipeline network renovation resource configuration information for the target pipeline network renovation area, an optimization model is established with the project construction sequence, pipeline network renovation resources, and the aggregated rainfall at the pipeline network nodes as constraints, and the shortest construction period as the optimization goal, to solve the pipeline network renovation planning strategy. As a result, the present invention improves the construction efficiency of urban pipeline network renovation tasks by rationally and scientifically planning the execution sequence and execution time period of each renovation project in the pipeline network renovation tasks of the target pipeline network renovation area, meets the construction sequence requirements of the rainwater pipeline network renovation location and the topological superimposed rainfall constraints, and minimizes the construction period and reduces construction costs.

[0030] In a preferred embodiment, the steps for obtaining the pipeline network reconstruction task in the target pipeline network reconstruction area specifically include: S110: receiving a pipeline network renovation demand information package for a target pipeline network renovation area uploaded by a survey and design terminal, extracting a regional pipeline network topology diagram and pipeline network renovation types of a plurality of pipeline network renovation points in the regional pipeline network topology diagram from the pipeline network renovation demand information package; The regional pipe network topology relationship diagram records the topological connection relationship of all rainwater pipe networks in the target pipe network reconstruction area, and the topological connection relationship includes a plurality of rainwater pipe network branches connected to each rainwater pipe network trunk line and a plurality of rainwater pipe network sources connected to each rainwater pipe network branch line; The pipe network renovation points are configured as the pipe network nodes to be renovated marked in the regional pipe network topology diagram, and the pipe network renovation types include rainwater pipe network source renovation, rainwater pipe network branch line renovation, and rainwater pipe network trunk line renovation; S120: Divide the target pipe network renovation area into a plurality of renovation sub-areas based on the deployment areas of all pipe network nodes to be renovated of a plurality of rainwater pipe network branches and a plurality of rainwater pipe network sources belonging to the same rainwater pipe network trunk line in the regional pipe network topology diagram; S130: Summarize the pipeline nodes to be renovated of the rainwater pipeline network branches and rainwater pipeline network sources contained in each renovation sub-area, and assign each pipeline node to be renovated of the rainwater pipeline network trunk to the nearest renovation sub-area, count the pipeline renovation type and project construction topological relationship position of each pipeline node to be renovated in each renovation sub-area, and generate a pipeline renovation task including the associated information of several renovation projects.

[0031] In this embodiment, first, by receiving professional data uploaded by the survey and design terminal (including the pipeline network renovation demand information package), the regional pipeline network topology relationship diagram (recording the connection logic of the trunk line, branch line, and source) and the pipeline network renovation point type (source / branch line / trunk line renovation) that can reflect the pipeline network structure are extracted, and then the renovation sub-areas are divided according to the branches and sources associated with the same trunk line to ensure that the topological association of the renovation projects in the sub-areas is close. Finally, the nodes to be renovated in the sub-areas are integrated, and the trunk nodes are allocated to the nearest sub-areas. The renovation type and topological position of each node are counted, and a renovation task containing the association information between the sub-areas and projects is generated to avoid omission or confusion of renovation objects.

[0032] In a preferred embodiment, the steps of extracting project attribute information of several renovation projects from the renovation project association information of each renovation sub-area and constructing a pipeline network renovation planning impact feature set for each renovation project under the pipeline network renovation task based on the project construction content and the project construction topological relationship position in the project attribute information specifically include: S210: Extracting the pipeline network renovation type and the project construction topological relationship position of all pipeline network nodes to be renovated from the renovation project association information of each renovation sub-area, converting the pipeline network renovation type into the corresponding project construction content, and generating project attribute information corresponding to the renovation project for each pipeline network node to be renovated based on the project construction content and the project construction topological relationship position; S220: Matching the project construction duration characteristics and project construction resource requirement characteristics of each renovation project according to the project construction content in the project attribute information, and using the project construction topological relationship position in the project attribute information as the project construction sequence characteristics of each renovation project; S230: Based on the project construction duration characteristics, project construction resource demand characteristics, and project construction sequence characteristics of each renovation project, a pipeline network renovation planning impact feature set is constructed for each renovation project.

[0033] In this embodiment, by converting abstract renovation projects into quantifiable planning parameters, the renovation type (source / branch / trunk) and the project construction topological relationship position of each node to be renovated are first extracted from the sub-region project association information. The renovation type is then mapped to specific construction content (e.g., source renovation corresponds to the renovation of residential building rainwater downpipes and the transfer of balcony wastewater pipes), generating project attribute information. Then, based on the construction content, the preset project construction duration characteristics (e.g., 4 days / building for source renovation) and project construction resource requirement characteristics (e.g., 2 plumbers + 1 hot melt machine) are matched. The topological position is directly used as the project construction sequence feature. Finally, the three types of features are integrated to form a three-dimensional feature set of "duration, resources, and sequence" for each project, providing standardized input data for the optimization model. Therefore, by visualizing the renovation projects as calculable feature parameters, the present invention ensures that the subsequent optimization model can accurately identify project differences, provide data support for resource allocation and sequence arrangement, and improve the scientific nature of planning.

[0034] In a preferred embodiment, rainfall forecast information and pipeline network renovation resource allocation information for the target pipeline network renovation area during the renovation planning period are obtained. Considering the project construction duration characteristics, project construction resource demand characteristics, and project construction sequence characteristics regarding the topological relationship of the project construction in the pipeline network renovation planning impact characteristics, a multi-constraint optimization model is used to solve the pipeline network renovation planning strategy steps, specifically including: S310: Accessing a meteorological forecast database to query rainfall forecast information for the target pipe network renovation area during the renovation planning period; wherein the rainfall forecast information includes rainfall forecast parameters for each rainwater pipe network source location within the target pipe network renovation area at each moment during the renovation planning period; S320: Querying the pipeline network renovation resource configuration information of the pipeline network renovation construction team for the target pipeline network renovation area during the renovation planning period; wherein the pipeline network renovation resource configuration information includes configuration information of pipeline network renovation construction equipment and pipeline network renovation construction personnel; S330: considering the project construction time length feature of the project construction content, the project construction resource demand feature and the project construction sequence feature of the project construction topological relationship position in the influence feature set of the pipe network reconstruction planning, taking the project construction time period of each reconstruction project as the first constraint condition, taking the equipment and personnel demand of the project construction resource feature of the project construction content of all reconstruction projects executed at the same time not exceeding the configuration information of the pipe network reconstruction construction equipment and the pipe network reconstruction construction personnel of the target pipe network reconstruction area in the reconstruction planning time period as the second constraint condition, taking the pipe network node summary rainfall of each reconstruction project at each time in the project construction time period being less than the rainfall parameter value allowed by the corresponding pipe network reconstruction type of the reconstruction project as the third constraint condition, taking the completion time of all reconstruction projects of the pipe network reconstruction task being the earliest as the optimization target, constructing an optimization model with multiple constraint conditions; S340: solving the optimization target by using an optimization algorithm to obtain the project construction time period of each reconstruction project in the project construction time period, and generating a pipe network reconstruction planning strategy.

[0035] In this embodiment, first, the rainfall prediction information (real-time rainfall parameter of each source position) and the resource configuration information (equipment and personnel quantity) are acquired to clearly define the external limiting conditions, then the earliest completion of all projects is taken as the optimization target, three rigid constraints are set: sequence constraint (construction after completion of previous project), resource constraint (resource demand of same period does not exceed configuration), rainfall constraint (summarized rainfall of construction time period does not exceed standard), to ensure the safety and feasibility of the planning, finally, the optimization algorithm is used to solve the model, and the construction time period of each project is output to form an executable strategy. In this way, the shortest construction period is realized under the premise of meeting the safety, quality and resource constraints, while avoiding the risk of construction in rainy days, and balancing efficiency and safety.

[0036] In a preferred embodiment, the project construction topological relationship position is configured as an array A [A1, A2, A3] recording the position parameter of each reconstruction project in the regional pipe network topological relationship graph; Wherein, A1 is the rainwater pipe network trunk line number of the reconstruction project in the regional pipe network topological relationship graph, A2 is the rainwater pipe network branch line number of the reconstruction project on the corresponding rainwater pipe network trunk line in the regional pipe network topological relationship graph, and A3 is the rainwater pipe network source number of the reconstruction project on the corresponding rainwater pipe network branch line in the regional pipe network topological relationship graph; Wherein, the project construction sequence feature is configured as the rainwater pipe network source on each rainwater pipe network branch line of each rainwater pipe network trunk line being the first priority construction sequence, the rainwater pipe network trunk line where each rainwater pipe network source is located being the second priority construction sequence, and the rainwater pipe network branch line where each rainwater pipe network source is located being the third priority construction sequence; Among them, when the renovation project is the renovation of the source of the stormwater pipe network, there is no previous renovation project; Among them, when the renovation project is the renovation of the rainwater pipe network trunk line, the previous renovation project of the renovation project is configured as the renovation of all rainwater pipe network sources on the rainwater pipe network trunk line; Among them, when the renovation project is the renovation of the rainwater pipe network branch line, the predecessor renovation project of the renovation project is the renovation of the rainwater pipe network trunk line and the renovation of all rainwater pipe network sources on the rainwater pipe network trunk line.

[0037] In this embodiment, the association logic between the topological position and the construction sequence is clarified through array positioning and priority sorting: first, the topological position is defined as the array A[A1, A2, A3] (A1=main line number, A2=branch line number, A3=source number) to achieve accurate positioning of the renovation project in the topology map, and then the construction sequence is set according to the source (first priority), main line (second priority), and branch line (third priority), and the preceding projects of different renovation types are clarified (for example, the preceding order of main line renovation is all source renovations, and the preceding order of branch line renovation is the main line and all source renovations), to ensure that the construction sequence complies with the pipeline convergence logic and avoid renovation failure.

[0038] For example, the topological position array of the trunk line reconstruction project is A[G2,3,0] (A1=G2 trunk line, A2=branch line 3, A3=0, no source number). According to the rules, its predecessor projects are all 8 source reconstructions on the G2 trunk line. The branch line reconstruction project array is A[G1,4,0], and the predecessor projects are the G1 trunk line reconstruction and 8 source reconstructions. The source reconstruction project array is A[G3,3,5], and there is no predecessor project, ensuring that the source is modified first, then the trunk line, and finally the branch line.

[0039] In a preferred embodiment, the aggregated rainfall at the pipe network node is configured as the sum of the rainfall prediction parameters of the location of each renovation project and all associated rainwater pipe network sources in the regional pipe network topology relationship diagram; Wherein, when the renovation project is the renovation of the source of the rainwater pipe network, the aggregated rainfall at the pipe network node is the rainfall prediction parameter at the location of the renovation project; Wherein, when the reconstruction project is the reconstruction of a rainwater pipe network branch line, the aggregated rainfall at the pipe network node is the sum of the rainfall prediction parameters at the locations of all rainwater pipe network sources on the rainwater pipe network branch line where the reconstruction project is located; Among them, when the renovation project is the renovation of the rainwater pipe network trunk line, the aggregated rainfall at the pipe network node is the sum of the rainfall prediction parameters at the locations of all rainwater pipe network sources on each rainwater pipe network branch line of the rainwater pipe network trunk line where the renovation project is located.

[0040] In this embodiment, source reconstruction is considered to be associated only with rainfall at its own location (without confluence), with the aggregated rainfall being the rainfall at its own location. Branch reconstruction is associated with rainfall at all connected sources (branches confluence source rainwater), with the aggregated rainfall being the sum of all associated source rainfall. Trunk reconstruction is associated with rainfall at all connected sources of all branches (trunks confluence all branches and source rainwater), with the aggregated rainfall being the sum of all associated source rainfall. This ensures that rainfall constraints cover the actual rainfall risks of the reconstruction project and the upstream confluence area, avoiding flooding accidents caused by underestimating rainfall. Thus, by accurately quantifying the actual rainfall risks of different reconstruction types, the limitations of traditional methods that only consider local rainfall are avoided, reducing the risk of foundation pit flooding accidents on rainy days. At the same time, clear aggregation rules facilitate model calculations and provide a precise parameter basis for rainfall constraints.

[0041] In a preferred embodiment, upon completion of each renovation project, the pipeline network renovation planning strategy is updated based on the newly acquired rainfall forecast information, the planned completion time of the unfinished renovation projects, and the pipeline network renovation planning impact feature set of the remaining renovation projects. Specifically, the steps include: S510: When each renovation project is completed, rainfall forecast information is re-obtained; S520: Determine whether the rainfall prediction parameters at each time point in the renovation planning period at the location of each rainwater pipe network source in the updated rainfall prediction information meet the third constraint condition in the multi-constraint optimization model for the unfinished renovation projects and the remaining renovation projects; S530: If yes, continue to execute the construction of each subsequent renovation project in the current pipeline network renovation planning strategy; If not, a new pipeline network renovation planning strategy is solved by reusing the multi-constraint optimization model based on the updated rainfall forecast information, the configuration information of pipeline network renovation construction equipment and pipeline network renovation construction personnel within the remaining renovation planning period determined by the planned completion time of the unfinished renovation projects, and the pipeline network renovation planning impact feature set of the remaining renovation projects. S550: Execute the construction of each renovation project in the updated pipeline network renovation planning strategy.

[0042] In this embodiment, after each project is completed, the latest rainfall forecast information is obtained again (the weather forecast may be adjusted) to determine whether the original construction period of the unfinished project still meets the rainfall constraint (the aggregated rainfall does not exceed the standard). If so, execution continues. If not, the optimization model is re-run to generate a new strategy based on the new rainfall information, remaining available resources, and remaining project characteristics to ensure that construction is always within a safe range and avoid delays due to emergencies such as rainfall forecast adjustments and project extensions. At the same time, it is ensured that construction is not forced to proceed during periods of rainfall exceeding the standard, further reducing safety risks and improving the flexibility and adaptability of planning.

[0043] Therefore, this embodiment constructs a set of pipeline renovation planning impact features, obtains rainfall forecast information and pipeline renovation resource allocation information for the target pipeline renovation area, establishes an optimization model with project construction sequence, pipeline renovation resources, and pipeline node aggregated rainfall as constraints, and takes the shortest construction period as the optimization goal, solves the project construction period for each renovation project within the project construction period, and generates a pipeline renovation planning strategy. Thus, by rationally and scientifically planning the execution sequence and execution period of each renovation project in the pipeline renovation task of the target pipeline renovation area, the present invention improves the construction efficiency of urban pipeline renovation tasks, meets the construction safety requirements of the rainwater pipeline renovation location and the topological superimposed rainfall constraint conditions, and shortens the construction period and reduces construction costs as much as possible.
