Description

Methods and Systems for Construction Quality Management of Urban Water Supply and Drainage Systems Technical Field

[0001] This application belongs to the technical field of construction quality management of urban water supply and drainage systems, and relates to a method and system for construction quality management of urban water supply and drainage systems. Background Technology

[0002] Urban water supply and drainage systems are an important component of urban infrastructure, comprising both water supply and drainage systems, which together ensure the city's water needs and treat wastewater.

[0003] To ensure the construction quality of urban water supply and drainage systems, water supply and drainage engineers are required to strictly review construction drawings before construction begins. They must also develop corresponding construction procedures based on the drawings. During construction, water supply and drainage engineers are responsible for the technical management of the construction site, such as tracking the construction progress, identifying and pointing out any non-standard operating methods that may exist during construction, coordinating with construction and supervision units to handle on-site technical issues, and finally participating in the final acceptance of the project.

[0004] In practical applications, due to the large construction area and numerous process nodes in water supply and drainage construction, it is difficult for on-site water supply and drainage engineers to conduct comprehensive quality monitoring and management of the entire construction process after the construction drawings have been reviewed and confirmed. As a result, some defects in the quality of the project may go unnoticed, which may pose a hidden danger to the stable operation of the entire water supply and drainage system in the later stage. Summary of the Invention

[0005] To address the problem that water supply and drainage engineers often struggle to comprehensively monitor the construction quality of water supply and drainage systems during practical applications, leading to potential construction defects in specific areas and impacting the future stable operation and lifespan of the system, this application aims to propose a construction quality management method for urban water supply and drainage systems. This method, by establishing a construction quality control model combined with on-site guidance from engineers and data entry, significantly improves the convenience and comprehensiveness of construction quality management, thus contributing to the overall improvement of project construction quality. To further implement this method, this application also aims to propose a construction quality management system for urban water supply and drainage systems. The specific solution is as follows: A construction quality management method for urban water supply and drainage systems includes: pre-setting and storing the construction difficulty coefficients corresponding to each construction site based on construction drawings; acquiring and storing the quality correlation coefficients between each construction site, and marking construction sites with quality correlation coefficients greater than a set value as associated construction sites; and based on the construction drawings and the pre-set construction parameters, construction difficulty coefficients, and the correlation coefficients between each construction site... Based on the spatial location relationship and quality correlation coefficient, a construction quality control model is constructed. Construction sites with a construction difficulty coefficient higher than a set value are selected as initial monitoring nodes. Actual construction parameters of each initial monitoring node are collected and entered at regular intervals. Based on the quality correlation coefficient stored in the construction quality control model, the expected construction parameters of the associated construction sites corresponding to the initial monitoring nodes are output. The above actual construction parameters and expected construction parameters are compared with the preset construction parameters corresponding to the relevant construction sites. If the deviation exceeds the set value, quality alarm information and quality warning information are output respectively. The construction difficulty coefficient is used to reflect the difficulty of achieving the preset construction parameters in the actual construction process. The definition standard of construction quality is the deviation of the actual construction parameters from the preset construction parameters. The quality correlation coefficient is used to reflect the mutual influence relationship between the construction quality of two construction sites. The construction sites include the construction location coordinates corresponding to each pipeline and its connection in the construction drawings. The construction parameters include the engineering parameters preset in the construction drawings and the process parameters preset in the construction process flow.

[0006] Through the above technical solutions, water supply and drainage engineers conducting on-site construction quality management can more effectively monitor construction sites that may have quality defects. They can also more easily input actual construction parameters into the system based on the construction quality control model. According to the quality correlation coefficients between associated construction sites configured in the construction quality control model, engineers can promptly identify potential construction quality problems. Simultaneously, various construction parameters throughout the entire construction process can be recorded, facilitating later project acceptance and significantly improving the convenience and comprehensiveness of water supply and drainage system construction quality management, thus contributing to the overall improvement of project construction quality.

[0007] Furthermore, the method for constructing the construction quality control model includes: acquiring construction drawings and converting them into an interactive interface based on an electronic display screen; numbering each construction site on the construction drawings, and storing the construction site number and its corresponding preset construction parameters, construction difficulty coefficient, spatial position relationship with other construction sites, and quality correlation coefficient; establishing the correspondence between the graphic symbols corresponding to each construction site on the interactive interface and the information interaction pop-up; establishing and storing the correlation between the display color of each graphic symbol and quality alarm information and quality warning information; establishing the correlation between user click actions and the content presented in the information interaction pop-up; wherein, based on the user's click action on the above-mentioned graphic symbols, an information interaction pop-up is output to record the actual construction parameters, query command information, and remarks information input by the user, or to display one or more combinations of preset construction parameters, construction difficulty coefficient, spatial position relationship with other construction sites, quality correlation coefficient, actual construction parameters, or historical remarks information associated with the construction site where the graphic symbol is located; if the construction site where the graphic symbol is located corresponds to quality alarm information or quality warning information, the graphic symbol is displayed by setting a color.

[0008] Through the above technical solutions, water supply and drainage engineers who conduct on-site construction quality management can quickly and conveniently input or view data related to each construction site using portable devices such as tablets. At the same time, the interactive interface of the above construction quality control model can clearly display the construction sites containing quality alarm information or quality warning information, making it convenient for engineers to know the construction progress and quality status of the entire system, which facilitates strengthening quality supervision or improving relevant construction techniques in subsequent construction, thereby improving project quality.

[0009] Furthermore, the construction quality management method also includes: counting the number of associated construction sites corresponding to each construction site, selecting construction sites with more than a set number of associated construction sites as initial monitoring nodes, and periodically collecting and recording the actual construction parameters of each initial monitoring node and its associated construction sites.

[0010] Through the above technical solution, the expected construction parameters of multiple related construction sites can be obtained by inputting the actual construction parameters of the initial monitoring nodes. This allows for early warning of potential quality problems during subsequent construction, enabling engineers to pay more targeted attention to the construction quality of one or more construction sites.

[0011] Furthermore, the construction quality management method also includes: configuring a construction error compensation scheme for each construction site according to the preset construction parameters corresponding to each construction site, and storing it in association with the construction site number; if there is quality alarm information or quality warning information corresponding to a construction site, the construction error compensation scheme corresponding to the above construction site is retrieved according to the user's click operation on the interactive interface.

[0012] With the above technical solution, when a construction quality problem occurs at a certain construction site, the on-site quality control engineer can directly obtain the corresponding compensation measures through a tablet computer, and carry out construction compensation for the completed construction site or the construction site about to start, thereby reducing the deviation between the actual construction parameters and the preset construction parameters.

[0013] Furthermore, the construction difficulty coefficient corresponding to each construction site is preset, including: acquiring and statistically analyzing the preset construction parameters and actual construction parameters of similar construction sites in each project, and calculating the deviation range between the two; excluding data interference items in the statistics, calculating the average deviation range of similar construction sites in each project, and preset the construction difficulty coefficient based on the average deviation range.

[0014] The above technical solution can calculate the construction difficulty coefficient corresponding to each construction site based on historical construction data, which helps on-site water supply and drainage engineers to identify key areas for quality monitoring and improve construction quality.

[0015] Furthermore, the construction quality management method also includes: setting the correlation between the construction difficulty coefficient and the environmental parameters of the construction site according to the construction parameters; acquiring the environmental parameters of the construction site in real time, and automatically correcting the construction difficulty coefficient associated with the relevant construction sites according to the above correlation; wherein, the environmental parameters include the temperature and humidity, rainfall, snowfall and wind speed of the construction site.

[0016] The above technical solutions can be used to adjust the construction difficulty coefficient of each construction site based on the environmental parameters of the construction site, thereby improving the efficiency of construction quality monitoring.

[0017] Furthermore, obtaining the quality correlation coefficient between each construction site includes: obtaining the construction parameters corresponding to the construction site on the construction drawings, and establishing a theoretical functional relationship between the construction parameters related to the spatial location between two adjacent construction sites based on the relative positional relationship between the two construction sites; or, obtaining the construction quality data of adjacent construction sites in each project, and statistically obtaining the quality correlation coefficient between each construction site.

The system includes one or more of the following: spatial relationship between construction sites, quality correlation coefficient, actual construction parameters, or historical remarks information; a construction data acquisition unit configured to select construction sites with a construction difficulty coefficient higher than a set value as initial monitoring nodes, and periodically collect and input the actual construction parameters of each initial monitoring node; a data processing unit configured to output the expected construction parameters of the associated construction sites corresponding to the initial monitoring nodes based on the quality correlation coefficient stored in the construction quality control model, and compare the above actual construction parameters and expected construction parameters with the preset construction parameters corresponding to the relevant construction sites respectively. If the deviation exceeds the set value, quality alarm information and quality warning information are output respectively; and an alarm information output unit configured to connect to the data storage unit and the data processing unit, and change the display color of the graphic marker according to the quality alarm information or quality warning information corresponding to the construction site where the graphic marker is located.

[0019] Furthermore, the system also includes a mode selection unit, configured to count the number of associated construction sites corresponding to each construction site according to the user's selection, select construction sites with more than a set value of associated construction sites as initial monitoring nodes, and periodically collect and record the actual construction parameters of each initial monitoring node and its associated construction sites.

[0020] Furthermore, the data storage unit also stores the construction error compensation schemes corresponding to each construction site and the correlation between the construction difficulty coefficient and the construction site environmental parameters; the system also includes: a construction deviation compensation unit, configured to detect and retrieve the construction error compensation schemes corresponding to the above-mentioned construction sites based on the user's click operation on the interactive interface; a construction site environmental parameter acquisition unit, configured to automatically or manually input the environmental parameters of the construction site; and a construction difficulty coefficient correction unit, configured to acquire the environmental parameters of the construction site and automatically correct the construction difficulty coefficient associated with the relevant construction sites based on the above correlation.

Detailed Implementation

[0024] The embodiments of this application are described in detail below, and examples of the embodiments are shown in the accompanying drawings.

[0025] In the description of this specification, the references to "certain embodiments," "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples" refer to specific features, structures, materials, or characteristics described in connection with the described embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] A construction quality management method for urban water supply and drainage systems, as shown in Figure 1, includes: S100, pre-setting and storing the construction difficulty coefficients corresponding to each construction site based on the construction drawings.

[0027] S200: Acquire and store the quality correlation coefficient between each construction site, and mark the construction sites with a quality correlation coefficient greater than the set value as associated construction sites; S300: Construct a construction quality control model based on the construction drawings and the preset construction parameters, construction difficulty coefficients, spatial position relationships and quality correlation coefficients between each construction site corresponding to each construction site; S400: Select construction sites with a construction difficulty coefficient higher than the set value as initial monitoring nodes, collect and record the actual construction parameters of each initial monitoring node at regular intervals, and output the expected construction parameters of the associated construction sites corresponding to the initial monitoring nodes based on the quality correlation coefficients stored in the construction quality control model; S500: Compare the above actual construction parameters and expected construction parameters with the preset construction parameters corresponding to the relevant construction sites respectively, and output quality alarm information and quality warning information respectively if the deviation exceeds the set value; In step S100, the construction drawings are CAD drawings, which are marked with data such as the location of inspection wells and pipelines, pipeline burial direction, pipeline diameter, trench width and depth, and gravel layer thickness. Construction sites include the coordinate points of the construction locations corresponding to each pipeline and its connection in the construction drawings. These coordinate points are generated based on the same reference coordinate system on the construction drawings. The construction difficulty coefficient is used to reflect the ease or difficulty of achieving the preset construction parameters during actual construction. In this embodiment, the preset construction difficulty coefficient corresponding to each construction site includes: S110, acquiring and statistically analyzing the preset construction parameters and actual construction parameters of similar construction sites in each project, and calculating the deviation range between the two; S111, excluding data interference items in the statistics, calculating the average deviation range of similar construction sites in each project, and preset the construction difficulty coefficient based on the average deviation range.

[0028] In practical applications, the numerical range of the above construction difficulty coefficient is set to 0-1. For example, 0-0.2 indicates no difficulty, requiring no on-site construction guidance or process control; 0.2-0.4 indicates easy, requiring experienced construction personnel to provide guidance during construction; 0.4-0.6 indicates moderate difficulty, requiring experienced construction personnel to participate in the construction; 0.6-0.8 indicates significant difficulty, requiring on-site guidance from a water supply and drainage engineer; and 0.8-1 indicates very high construction difficulty, requiring on-site guidance from a water supply and drainage engineer based on construction drawings and parameters, and requiring experienced construction personnel to carry out the construction.

[0029] In this application, the standard for defining construction quality is the deviation of actual construction parameters from preset construction parameters, such as the deviation between the actual excavation depth of the trench and the preset depth, or the deviation between the strength of the poured concrete and the preset strength.

[0030] Construction parameters include the engineering parameters preset in the construction drawings and the process parameters preset in the construction process flow.

[0031] In step S200, the quality correlation coefficient is used to reflect the mutual influence between the construction quality of two construction sites. For example, when the pipe burial depth deviates by 10cm, the burial depth of the prefabricated inspection well (usually made of PVC material with an opening for connection to the drainage pipe) will also deviate by 10cm. Similarly, when the pipe laying angle deviates from the preset angle, it will cause a deviation in the actual required laying length of the pipe. For another example, the deviation in the soil compaction degree of the inspection well pit will affect the settlement of the inspection well. In short, the deviation in the actual construction parameters of construction site A will be transmitted to construction site B. The deviation introduced during the above construction process will eventually disappear after correction by one or more construction sites.

[0032] In this application, the quality correlation coefficients between various construction sites are obtained as follows:

[0033] S210: Obtain the construction parameters corresponding to the construction sites on the construction drawings. Based on the relative positional relationship between two adjacent construction sites, establish a theoretical functional relationship between the spatially related construction parameters of the two construction sites. For example, if the depth of construction site A increases by 10cm, the depth of construction site B will decrease by 5cm. Alternatively, S211: Obtain the construction quality data of adjacent construction sites in each project and statistically determine the quality correlation coefficient between each construction site. For example, by statistically analyzing the soil compaction degree at the bottom of each manhole and the settlement data of the manhole after a set time, the correlation between the manhole settlement amplitude and the soil compaction degree can be obtained.

[0034] In step S300, the method for constructing the construction quality control model includes: S310, acquiring construction drawings and converting them into an interactive interface based on an electronic display screen.

[0035] S311 is the construction drawing, which is to number each construction site in the interactive interface, and to store each construction site number and its corresponding preset construction parameters, construction difficulty coefficient, spatial position relationship with other construction sites, and quality correlation coefficient.

[0036] S312, establish the correspondence between the graphic markers corresponding to each construction site on the interactive interface and the information interaction pop-up windows. In this embodiment, the information interaction pop-up windows are preferably displayed next to the graphic markers, but can also be displayed in the right side area of ​​the interactive interface. In use, the system detects and outputs information interaction pop-ups based on the user's actions of clicking the graphic markers, such as double-clicking, right-clicking, or clicking the set virtual command buttons. These pop-ups are used to input the actual construction parameters, query command information, and remarks information entered by the user, or to display one or more combinations of preset construction parameters, construction difficulty coefficient, spatial positional relationship with other construction sites, quality correlation coefficient, actual construction parameters, or historical remarks information associated with the construction site where the graphic marker is located.

[0037] S313, Establish and store the association between the display color of each graphic marker and the quality alarm information and quality warning information. If the construction site where the graphic marker is located corresponds to quality alarm information or quality warning information, then the graphic marker is displayed by setting a color. In this embodiment, the graphic marker corresponding to quality alarm information is displayed in red, the graphic marker corresponding to quality warning information is displayed in yellow, and the normal graphic marker is displayed in green.

[0038] S314, Establish and store the association between user click actions and the content presented in the information interaction pop-up, such as double-clicking, right-clicking and other operations corresponding to different pop-up content.

[0039] Based on the above technical solution, water supply and drainage engineers who conduct on-site construction quality management can quickly and conveniently input or view data related to each construction site using portable devices such as tablets. At the same time, the interactive interface of the above construction quality control model can clearly display the construction sites containing quality alarm information or quality warning information, making it convenient for engineers to know the construction progress and quality status of the entire system, which facilitates strengthening quality supervision or improving relevant construction techniques in subsequent construction, thereby improving project quality.

[0040] In step S400, construction sites with a difficulty coefficient higher than the set value are selected as initial monitoring nodes. This allows water supply and drainage engineers conducting on-site construction quality management to more effectively monitor construction sites that may have quality defects. The actual construction parameters can be collected at set intervals or at set times after each construction site is completed, such as collecting concrete strength data 3 days and 28 days after concrete pouring.

[0041] In the optimized version of this application, the construction quality management method further includes: counting the number of associated construction sites corresponding to each construction site, selecting construction sites with more than a set number of associated construction sites as initial monitoring nodes, and periodically collecting and recording the actual construction parameters of each initial monitoring node and its associated construction sites.

[0042] The above technical solution obtains the expected construction parameters of multiple related construction sites by inputting the actual construction parameters of the initial monitoring nodes, thereby providing early warnings of potential quality problems during subsequent construction and enabling engineers to pay more targeted attention to the construction quality of one or more construction sites.

[0043] Following step S500, the construction quality management method further includes a construction compensation step: Based on the preset construction parameters corresponding to each construction site, a construction error compensation plan is configured for each construction site and stored in association with each construction site number. For example, if the thickness of the crushed stone layer is insufficient, the compensation plan is to add more crushed stone and lay it evenly; if the pipe length cannot meet the requirements due to the offset of the pipe laying angle, a pipe connection plan is provided. If there is quality alarm information or quality warning information corresponding to a construction site, the construction error compensation plan corresponding to the aforementioned construction site is retrieved based on the user's click operation on the interactive interface. Therefore, when a construction quality problem occurs at a certain construction site, the on-site quality control engineer can directly obtain the corresponding compensation measures via a tablet computer and work with workers to compensate for the completed or upcoming construction sites, reducing the deviation between the actual construction parameters and the preset construction parameters.

[0044] The construction process of urban water supply and drainage systems is often affected by environmental parameters at the construction site. For example, rainy weather can cause water to accumulate in the trenches where pipes are laid, which can increase the measurement error of the trench depth and the compaction of the soil at the bottom of the trench. In order to ensure construction quality, the construction quality management method described in this application also includes: S710, setting the correlation between the construction difficulty coefficient and the environmental parameters at the construction site based on the construction parameters. The above correlation is set by the engineer based on the experience of construction and quality management. For example, low temperature rain and snow will increase the value of the masonry difficulty coefficient of the slope protection by 0.1.

[0045] S711 acquires environmental parameters of the construction site in real time and automatically corrects the construction difficulty coefficient associated with the relevant construction sites based on the above-mentioned correlation.

[0046] The aforementioned environmental parameters include temperature and humidity, rainfall, snowfall, and wind speed at the construction site.

Model storage unit 2 is configured to store the aforementioned construction quality control model.

[0049] Interaction unit 3 includes an interactive interface designed based on construction drawings, which is used to detect and output an interactive pop-up window based on the user's action of clicking the above-mentioned graphic mark. This pop-up window is used to input the actual construction parameters, query instructions and remarks entered by the user, or to display one or more of the following stored preset construction parameters, construction difficulty coefficient, spatial positional relationship with other construction sites, quality correlation coefficient, actual construction parameters or historical remarks associated with the construction site where the above-mentioned graphic mark is located: construction parameters, construction difficulty coefficient, spatial positional relationship with other construction sites, quality correlation coefficient, actual construction parameters or historical remarks.

[0050] The construction data acquisition unit 4 is configured to select construction sites with a construction difficulty coefficient higher than the set value as initial monitoring nodes, and automatically or by the user collect and input the actual construction parameters of each initial monitoring node.

[0051] Data processing unit 5 is configured to output the expected construction parameters of the associated construction sites corresponding to the initial monitoring nodes based on the quality correlation coefficients stored in the construction quality control model. It compares the actual and expected construction parameters with the preset construction parameters corresponding to the relevant construction sites. If the deviation exceeds a set value, it outputs quality alarm information and quality warning information respectively. Alarm information output unit 10 is configured to connect to data storage unit 1 and data processing unit 5, and changes the display color of the graphic marker according to the quality alarm information or quality warning information corresponding to the construction site where the graphic marker is located.
