Description

Technical Field

[0001] The present invention relates to the field of drainage pipeline detection and informatization construction, and particularly relates to a system for storing and evaluating drainage pipeline detection results. Background Art

[0002] With the rapid development of cities and the coexistence of old and new urban areas, the drainage system still coexists in a combined sewer system and a separate sewer system, which inevitably leads to problems of wrong connection and rain - sewage mixing.

[0003] Due to the emphasis on construction and neglect of management in the drainage system, during the long - term operation of the drainage pipeline network, functional defects such as gradual sedimentation and scaling, as well as structural defects such as rupture and deformation, occur inside the pipeline. The continuous deterioration of pipeline defects leads to the abnormal operation of the pipeline and affects the normal drainage of the city. Summary of the Invention

[0004] In view of the technical defects and drawbacks existing in the prior art, the embodiments of the present invention provide a system for storing and evaluating drainage pipeline detection results to overcome or at least partially solve the above - mentioned problems. The specific solutions are as follows:

[0005] A system for storing and evaluating drainage pipeline detection results includes:

[0006] A data import module for importing drainage pipeline network detection data, where the drainage pipeline network detection data includes defect detection data of all pipelines;

[0007] A defect management module for spatially associating and presenting the defect detection data of each pipeline with a GIS map, so that the imported defect detection data is visualized on the GIS map;

[0008] A pipeline evaluation module for setting different location areas based on the GIS map, selecting corresponding areas in the form of a custom polygon, setting the importance parameter K of the corresponding area, and simultaneously setting the soil quality influence parameter T of the corresponding area. Combining the pipeline importance parameter E and the defect detection data, it calculates the pipeline defect evaluation and repair index RI and the pipeline defect evaluation and maintenance index MI;

[0009] A rendering and display module for calculating the evaluation result according to the pipeline defect evaluation and repair index RI and the pipeline defect evaluation and maintenance index MI, combining the pipeline repair grade division table and the pipeline maintenance grade division table, automatically calculating the comprehensive evaluation of different pipelines, and rendering and displaying the relevant pipelines through the GIS map.

[0010] Further, the data import module is also used to sort out the imported drainage network detection data, classify the defects of drainage pipes into structural and functional defects, organize the types, grades and scores of the structural and functional defects of drainage pipes, and construct a defect detection form based on the sorted drainage network detection data. The defect detection form includes fields such as pipe number, defect type, defect grade, detection length, pipe diameter, and defect score.

[0011] Further, the types of structural defects include rupture, deformation, offset, disconnection, leakage, undulation, foreign object penetration, branch pipe hidden connection, corrosion, and interface material shedding. The types of functional defects include sedimentation, scaling, obstacles, residual wall dam roots, tree roots, and scum. Each type of defect includes multiple defect grades, and each defect grade corresponds to a defect score.

[0012] Further, set the importance parameter K of the corresponding area, and at the same time set the soil quality influence parameter T of the corresponding area. The calculation of the pipeline defect evaluation and repair index RI and the pipeline defect evaluation and maintenance index MI in combination with the pipeline importance parameter E and the defect detection data includes:

[0013] Calculate the corresponding functional defect parameter G and functional defect density Y through the pipe number, defect type, defect grade, detection length, pipe diameter, and defect score data of each pipeline entered in the defect detection form M 、structural defect parameter F and structural defect density S M ;

[0014] Based on the functional defect parameter G, functional defect density Y M 、structural defect parameter F and structural defect density S M , in combination with the area importance parameter K, soil quality influence parameter T, and pipeline importance parameter E, complete the calculation and evaluation of the pipeline defect evaluation and repair index RI and the pipeline defect evaluation and maintenance index MI;

[0015] Among them:

[0016] The calculation formula of the pipeline defect evaluation and repair index RI is:

[0017] RI = 0.7×F + 0.1×K + 0.05×E + 0.15×T;

[0018] The calculation method of the pipeline defect evaluation and maintenance index MI is as follows:

[0019] MI = 0.8×G + 0.15×K + 0.05×E.

[0020] Further, the evaluation result is calculated based on the pipeline defect evaluation repair index RI and the pipeline defect evaluation maintenance index MI. Combining the pipeline repair grade division table and the pipeline maintenance grade division table, the comprehensive evaluation of different pipelines is automatically calculated, including:

[0021] Construct a pipeline repair grade division table and a pipeline maintenance grade division table. The pipeline repair grade division table includes the value range of the pipeline defect evaluation repair index RI corresponding to different repair grades, as well as the repair suggestions and instructions corresponding to different repair grades. The pipeline maintenance grade division table includes the value range of the pipeline defect evaluation maintenance index MI corresponding to different maintenance grades, as well as the repair suggestions and instructions corresponding to different maintenance grades.

[0022] Based on the calculated pipeline defect evaluation repair index RI, the rendering and display module queries the pipeline repair grade division table to determine the corresponding repair grade, repair suggestions and instructions. Based on the calculated pipeline defect evaluation maintenance index MI, the pipeline maintenance grade division table is queried to determine the corresponding maintenance grade and maintenance suggestions and instructions, so as to obtain the comprehensive evaluation of different pipelines.

[0023] Further:

[0024] The repair grades include four grades:

For the existing drainage pipelines that have been put into operation, the repair suggestions and instructions are that the structural conditions are basically intact and no repair is required. For the newly built drainage pipelines to be handed over, the repair suggestions and instructions are that the structural conditions are basically intact and no repair is required.

[0026] For the second grade, RI is greater than 1 and less than or equal to 4. For the existing drainage pipelines that have been put into operation, the repair suggestions and instructions are that the structure will not be damaged in the short term, but a repair plan should be made. For the newly built drainage pipelines to be handed over, the repair suggestions and instructions are that there are certain structural defects in the pipeline. The defects of undulation, offset and interface material shedding can be temporarily not repaired, but a repair plan should be made. Other structural defects should be repaired immediately.

[0027] For the third grade, RI is greater than 4 and less than or equal to 7. For the existing drainage pipelines that have been put into operation, the repair suggestions and instructions are that the structure may be damaged in the short term and should be repaired as soon as possible. For the newly built drainage pipelines to be handed over, the repair suggestions and instructions are that the structure may have been damaged or has been damaged in the short term and should be repaired immediately.

[0028] For the fourth grade, RI is greater than 7. For the existing drainage pipelines that have been put into operation, the repair suggestions and instructions are that the structure has been damaged or is about to be damaged and should be repaired immediately. For the newly built drainage pipelines to be handed over, the repair suggestions and instructions are that the structure may have been damaged or has been damaged in the short term and should be repaired immediately.

[0029] Furthermore:

[0030] The maintenance level includes four levels:

[0031] For the first level, the MI is less than or equal to 1. For existing drainage pipes that have been put into operation, the maintenance suggestions and descriptions are that there are no obvious defects that need to be processed. For newly built drainage pipes to be handed over, the maintenance suggestions and descriptions are that there are no obvious defects that need to be processed;

[0032] For the second level, the MI is greater than 1 and less than or equal to 4. For existing drainage pipes that have been put into operation, the maintenance suggestions and descriptions are that there is no immediate need for treatment, but a treatment plan should be arranged. For newly built drainage pipes to be handed over, the maintenance suggestions and descriptions are that the flow-through of the pipe is blocked to a certain extent and should be processed before handover;

[0033] For the third level, the MI is greater than 4 and less than or equal to 7. For existing drainage pipes that have been put into operation, the maintenance suggestions and descriptions are that comprehensive consideration should be given based on the basic data and it should be processed as soon as possible. For newly built drainage pipes to be handed over, the maintenance suggestions and descriptions are that the flow-through of the pipe is severely blocked and should be processed immediately;

[0034] For the fourth level, the MI is greater than 7. For existing drainage pipes that have been put into operation, the maintenance suggestions and descriptions are that the water conveyance function is severely affected and should be processed immediately. For newly built drainage pipes to be handed over, the maintenance suggestions and descriptions are that the flow-through of the pipe is severely blocked and should be processed immediately.

[0035] Furthermore, the system further includes a statistical analysis module, which is used to conduct statistical analysis on structural defects, functional defects, defect ratio length, repair index, maintenance index, and the statistics of defects and pipe attributes for different defect levels and categories, and analyze the influence of the attributes of different pipes on pipe defects based on the statistical results.

[0036] Furthermore, the system further includes a result management module, which is used to manage the pipe defect data, display the sediment longitudinal section, generate statistical reports and conduct defect assessments based on the defect assessment results of pipes in different regions, centrally manage the pipe assessment results through a resource directory tree, and support online preview and download of the results.

Among them, for structural early warning, thresholds for the repair index, structural defect parameters, and structural defect density of the pipe are set, and for functional early warning, thresholds for the maintenance index, functional defect parameters, and functional defect density of the pipe are set to achieve over-limit early warning of pipe assessment results, and display the repair and maintenance conditions of the pipe in the form of a thematic map.
