Description

Technical Field

[0001] This invention relates to the field of information technology for construction quality management, specifically to a sleeve grouting quality traceability system and method. Background Technology

[0002] In prefabricated buildings, the construction quality of grouting connections for rebar sleeves directly affects the integrity and safety of the building structure. Currently, quality control of this critical process still mainly relies on traditional management methods, namely manual paper records and on-site supervision. This model has the following inherent drawbacks:

[0003] Information management is inefficient: Construction records, inspection forms, etc. are all in paper form, which leads to fragmented information that is easy to lose or damage. Furthermore, the subsequent sorting, archiving, and retrieval work is extremely cumbersome and inefficient.

[0004] Blind spots in process supervision: It is impossible to record and monitor the entire grouting construction process (such as grout preparation and grouting operation) in real time and objectively. The lack of key video data makes it difficult to trace the source of quality problems and determine responsibility when they occur.

[0005] Data lag and silos: The transmission of information such as on-site inspection data and rectification instructions relies on manual processes, resulting in significant time delays. Data cannot be shared and linked in real time between different stages (such as inspection, construction, and acceptance), leading to slow problem response and rectification loop closure, and lagging quality control.

[0006] Weak process control: Pre-grouting condition checks (such as work interface, connecting steel bars, etc.) and the issuance of grouting orders rely heavily on personnel experience and self-discipline, lacking mandatory and traceable electronic process control, which poses potential quality risks.

[0007] Currently, although the level of information management in the construction industry is gradually improving, and some general construction management systems have emerged, there is still no system specifically designed for integrated, real-time, and traceable management of the entire process of rebar sleeve grouting (from construction preparation, pre-grouting inspection, grout preparation, grouting construction to post-grouting inspection). Therefore, there is an urgent need for a system and method that can overcome the above-mentioned shortcomings and achieve full-process digital and traceable management of sleeve grouting quality. Summary of the Invention

[0008] The purpose of this invention is to provide a sleeve grouting quality traceability system and method to solve the problem that there is currently no system or method that can provide integrated, real-time, and traceable management of the entire process of rebar sleeve grouting.

[0009] To address the aforementioned technical problems, in a first aspect, the present invention provides a sleeve grouting quality traceability system, comprising:

[0010] The information entry module is used to enter basic project information, including construction location, construction time, workers, and component numbers.

[0011] The pre-grouting inspection module is used to record the working interface of the sleeve, the connecting steel bars, and the compartment inspection data; when any pre-grouting inspection data is abnormal, a rectification process is initiated; when the working interface of the sleeve, the connecting steel bars, and the compartment inspection data all meet the requirements, an electronic grouting order is generated.

[0012] The grouting construction inspection module is used to select components to be grouted from engineering design drawings and record grouting construction process data.

[0013] The post-grouting inspection module is used to record quality inspection data after grouting is completed.

[0014] The management and control platform is used to set up access control, process approval, and to acquire, archive and store data information uploaded in real time by the information entry module, the pre-grouting inspection module, the grouting construction inspection module and the post-grouting inspection module.

[0015] Furthermore, the working interface inspection of the sleeve includes:

[0016] Check that any debris or trash inside the sleeve has been cleaned.

[0017] Check whether the grouting holes or grout outlets are intact and clean;

[0018] Check if the sleeve is unobstructed;

[0019] The inspection of the connecting steel bars of the sleeve includes:

[0020] Check that the surface of the connecting steel bars is clean and free of rust;

[0021] Check whether the position and length of the connecting steel bars meet the requirements;

[0022] The compartmentalized inspection of the sleeve includes:

[0023] Check whether the sleeve compartment material meets the requirements;

[0024] Check the compartmentation of the sleeve, including whether it is compartmentalized and whether the compartmentation method meets the design requirements.

[0025] Furthermore, the grouting construction process data includes material preparation data, grout preparation data, grout mixture test data, and work record data;

[0026] Material preparation data includes: whether the equipment is complete and meets the grouting construction requirements (equipment includes thermometer, electronic scale, graduated cup, slurry mixing bucket, water bucket, hand mixer, grouting gun, grouting pump, truncated cone mold, glass plate, steel ruler, triple mold, etc.) and grouting material information (including brand, whether it is qualified, expiration date, etc.).

[0027] Slurry preparation data includes: slurry batch, dry powder and water usage, stirring time, ambient temperature, and data on abnormal phenomena in slurry preparation;

[0028] The test data for the slurry mixture includes: fluidity test, specimen retention, and number of specimen retention groups;

[0029] The work record data includes: the number of the grout outlet / inlet, whether grout is flowing from the grout outlet / inlet, whether the sealing of the grout outlet / inlet meets the specifications, and data on abnormal phenomena in the work (grouting and repair measures, plugging and re-grouting measures, etc.).

[0030] Furthermore, the quality inspection after grouting is completed includes: the fullness of grout in / out and whether there is a supervisor present.

[0031] Furthermore, the system employs a hybrid networking approach for data transmission, including one or more of 4G, LoRa, NB-IoT, and Wi-Fi.

[0032] Furthermore, the system uses the message middleware Kafka to process data.

[0033] Secondly, the present invention provides a method for tracing the quality of grouting in a cylinder, comprising the following steps:

[0034] S1: Enter basic project information through the information entry module;

[0035] S2: Record the working interface of the sleeve, the connecting steel bars, and the compartment inspection data through the pre-grouting inspection module; if any pre-grouting inspection data is abnormal, a rectification process is initiated; when the working interface of the sleeve, the connecting steel bars, and the compartment inspection data all meet the requirements, an electronic grouting order is generated.

[0036] S3: Select the components to be grouted from the engineering design drawings through the grouting construction inspection module, and record the grouting construction process data;

[0037] S4: Record the quality inspection data after grouting is completed through the post-grouting inspection module;

[0038] S5: Through the management and control platform, you can set up access control, process approval, and data information that is uploaded to the management and control platform in real time by the information entry module, the pre-grouting inspection module, the grouting construction inspection module, and the post-grouting inspection module.

[0039] The beneficial effects of this invention are as follows: The system uses four modules—information entry, pre-grouting inspection, grouting construction inspection, and post-grouting inspection—to collect and seamlessly connect the data of the entire process of sleeve grouting operation in a structured manner, and upload it to the management and control platform for centralized archiving in real time; forming a complete and tamper-proof "electronic quality archive," which completely solves the problems of easy loss and difficulty in querying paper records, and realizes forward tracking and reverse traceability of quality problems from component to grouting process.

[0043] Figure 3 This is a schematic diagram of the grouting construction inspection items according to an embodiment of the present invention. Detailed Implementation

[0044] Firstly, such as Figure 1 The sleeve grouting quality traceability system shown includes

[0045] The information entry module is used to enter basic project information, including construction location, construction time, workers, and component numbers.

[0046] The pre-grouting inspection module is used to record the working interface of the sleeve, the connecting steel bars, and the compartment inspection data; when any pre-grouting inspection data is abnormal, a rectification process is initiated; when the working interface of the sleeve, the connecting steel bars, and the compartment inspection data all meet the requirements, an electronic grouting order is generated.

[0047] The grouting construction inspection module is used to select components to be grouted from engineering design drawings and record grouting construction process data.

[0048] The post-grouting inspection module is used to record quality inspection data after grouting is completed.

[0049] The management and control platform is used to set up access control, process approval, and to acquire, archive and store data information uploaded in real time by the information entry module, the pre-grouting inspection module, the grouting construction inspection module and the post-grouting inspection module.

[0050] The system uses four modules—information entry, pre-grouting inspection, grouting construction inspection, and post-grouting inspection—to collect and seamlessly connect data from the entire process of sleeve grouting operations in a structured manner, and upload it to the management and control platform for centralized archiving in real time. This forms a complete and tamper-proof "electronic quality archive," which completely solves the problems of paper records being easy to lose and difficult to search, and realizes forward tracking and reverse traceability of quality problems from the entire process from component to grouting.

[0051] According to one embodiment of this application, the working interface inspection of the sleeve includes:

[0052] Check that any debris or trash inside the sleeve has been cleaned.

[0053] Check whether the grouting holes or grout outlets are intact and clean;

[0054] Check if the sleeve is unobstructed;

[0055] The inspection of the connecting steel bars of the sleeve includes:

[0056] Check that the surface of the connecting steel bars is clean and free of rust;

[0057] Check whether the position and length of the connecting steel bars meet the requirements;

[0058] The compartmentalized inspection of the sleeve includes:

[0059] Check whether the sleeve compartment material meets the requirements;

[0060] Check the compartmentation of the sleeve, including whether it is compartmentalized and whether the compartmentation method meets the design requirements.

[0061] This embodiment clarifies the specific items that must be checked before grouting, providing specific and executable judgment criteria for the generation of "electronic grouting orders" and eliminating potential quality risks from the source.

[0062] The prerequisite for grouting construction is that all prior inspections (work interface, connecting steel bars, compartments, etc.) must be qualified. Any abnormality will trigger the rectification process. The system introduces a mandatory "electronic grouting order" mechanism, which requires the consent of the person in charge and the signatures of the quality inspector and the supervisor before construction can begin. This technically eliminates the possibility of skipping the inspection process and constructing with defects, moves the quality control checkpoint forward, and transforms post-event remediation into pre-event prevention and strict in-process control, fundamentally reducing quality risks.

[0063] According to one embodiment of this application, the grouting construction process data includes material preparation data, grout preparation data, grout mixture test data, and work record data.

[0064] Material preparation data includes: whether the equipment is complete and meets the grouting construction requirements (equipment includes thermometer, electronic scale, graduated cup, grout mixing bucket, water bucket, hand mixer, grouting gun, grouting pump, truncated cone mold, glass plate, steel ruler, triple mold, etc.) and grouting material information (including grouting material brand, quality qualification, expiration date, etc.).

[0065] Slurry preparation data includes: slurry batch, dry powder and water usage, stirring time, ambient temperature, and data on abnormal phenomena in slurry preparation;

[0066] The test data for the slurry mixture includes: fluidity test, specimen retention, and number of specimen retention groups;

[0067] Work record data includes: grout inlet / outlet number, whether grout is flowing from the grout inlet / outlet, whether the grout inlet / outlet sealing meets specifications, and data on abnormal operations (grouting and repair measures, plugging and re-grouting measures, etc.).

[0068] The system records detailed data on grout preparation (such as proportions and mixing time), grout mixture testing (such as fluidity), and grouting operation (such as inlet / outlet conditions). These key process parameters are objectively recorded and can be supplemented with video footage as needed, making the grouting process transparent, visible, and verifiable. This greatly reduces human interference and subjective judgment errors, providing a reliable basis for quality assessment.

[0069] According to one embodiment of this application, the quality inspection after grouting is completed includes: the fullness of grout in / out (i.e., the density of grout in / out) and whether there is a supervisor present.

[0070] According to one embodiment of this application, the system employs a hybrid networking approach for data transmission, including one or more of 4G, LoRa, NB-IoT, and Wi-Fi. This hybrid networking approach allows the system to flexibly adapt to the complex and harsh network environment of construction sites, ensuring stable data transmission.

[0071] According to one embodiment of this application, the system uses the message middleware Kafka to process data. Utilizing Kafka to handle high-concurrency, massive amounts of IoT and business data ensures the system's response speed and stability under high load, providing a solid technical foundation for the system's large-scale and routine application.

[0072] Secondly, this invention discloses a method for tracing the quality of sleeve grouting, comprising the following steps:

[0073] S1: Enter basic project information through the information entry module;

[0074] S2: Record the working interface of the sleeve, the connecting steel bars, and the compartment inspection data through the pre-grouting inspection module; if any pre-grouting inspection data is abnormal, a rectification process is initiated; when the working interface of the sleeve, the connecting steel bars, and the compartment inspection data all meet the requirements, an electronic grouting order is generated.

[0075] S3: Select the components to be grouted from the engineering design drawings through the grouting construction inspection module, and record the grouting construction process data;

[0076] S4: Record the quality inspection data after grouting is completed through the post-grouting inspection module;

[0077] S5: Set up permission management and process approval through the management and control platform, and acquire, archive and store data information uploaded to the management and control platform in real time by the information entry module, grouting pre-inspection module, grouting construction inspection module and grouting post-inspection module.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the invention.
