Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of underground pipeline repair, in particular to a pre-inspection system for underground pipeline trenchless repair and a working condition judgment method. BACKGROUND

[0002] As a key component of urban infrastructure, municipal drainage pipelines bear the important mission of discharging rainwater and transporting sewage. However, as the service life of the pipeline increases, sediments, tree roots and other debris gradually accumulate inside the pipeline, which seriously affects the transportation efficiency of the pipeline. In addition, the pipeline may also have structural problems such as corrosion, damage, misalignment and disconnection, which pose a great safety hazard. Therefore, the pipeline needs to be repaired. Trenchless repair is an important way of pipeline repair at present, and it is particularly important to thoroughly pretreat the pipeline before underground pipeline trenchless repair. The pretreatment work includes but is not limited to cleaning the accumulated water, sediments, tree roots and other debris in the pipeline, and drying the pipeline under special working conditions to ensure the cleanliness and dryness of the pipeline interior. The effect of pipeline pretreatment is directly related to the long-term performance, construction safety and construction quality of trenchless repair. If the pretreatment is not thorough, the repair material may not be effectively attached to the inner wall of the pipeline, thereby affecting the repair effect; at the same time, the residual debris may also cause safety problems during construction. In addition, different trenchless repair processes have different requirements for the working conditions of the pipeline, for example, some processes may require the inner wall of the pipeline to reach a certain degree of dryness or cleanliness.

[0003] At present, there are various instruments and equipment for pipeline inspection on the market, which can collect various working condition parameters inside the pipeline, such as water depth, sediment thickness, water content of the pipe wall and pipe wall protrusions, providing important equipment support and data acquisition support for post-treatment detection of the pipeline. However, after obtaining these data, how to quickly and accurately judge whether the pipeline pretreatment effect meets the requirements of the construction process is still a problem to be solved.

[0004] The traditional method relies on manual interpretation and judgment of inspection data, which is not only inefficient, but also easily affected by human factors, leading to subjectivity and inconsistency of the judgment results. Therefore, it is particularly important to develop a pre-inspection system that can automatically, quickly and accurately judge the pipeline pretreatment effect and working conditions. This system not only improves the efficiency and accuracy of pipeline pretreatment effect evaluation, but also provides strong data support for subsequent trenchless repair construction, thereby ensuring the safety and quality of construction.

[0039] A determination method for a trenchless repair working condition of an underground pipeline, comprising the following steps:

[0040] Before repairing a city water supply pipeline using an ultraviolet light curing trenchless repair process, in order to ensure the repair effect, the pre-inspection system for trenchless repair of an underground pipeline and the determination method for the working condition of the trenchless repair are applied. The specific steps and details are as follows:

[0041] Step one, use the data acquisition and receiving module to collect the working condition parameters of the water depth, sediment thickness, and pipe wall moisture in the underground pipeline. The specific details are as follows: deploy high-sensitivity sensors in the drainage pipeline to be repaired for real-time collection of key working condition parameters such as the water depth of the inner wall of the pipeline, the thickness of the sediment, the moisture of the pipe wall, and possible pollutant residues. The sensor transmits the collected data to the data receiving module of the pre-inspection system through wireless communication technology, which preliminarily checks and arranges the received data to ensure the integrity and accuracy of the data.

[0042] Step two, the data preprocessing module cleans and processes the collected working condition parameters in a unified format to generate a standardized data set. The specific details are as follows: the data preprocessing module receives data from the data receiving module, first filters out noise and removes outliers to ensure data quality. Then, format the data, including converting the working condition parameters such as sediment thickness and water depth to a unified unit, quantifying the pipe wall moisture, and paying special attention to and processing the cleanliness and dryness parameter values of the inner wall of the pipeline according to the requirements of the ultraviolet light curing repair process. According to the different sections and working condition characteristics of the pipeline, the data is coded and classified for subsequent analysis.

[0043] Step three, in the working condition parameter matching module, the processed working condition parameters are matched with the preset process parameter standard. The specific details are as follows: the working condition parameter matching module presets the corresponding working condition parameter standard according to the specific requirements of the ultraviolet light curing repair process. These standards include but are not limited to the cleanliness threshold of the inner wall of the pipeline, the dryness requirement, the proportion of the water-free area, etc. The actual working condition parameters after preprocessing are compared and matched with the preset standard, and it is preliminarily evaluated whether the pipeline meets the prerequisite conditions for ultraviolet light curing repair.

[0044] Step four, the matched data are compared and analyzed by using the working condition parameter comparison and analysis module, and it is evaluated whether the pipeline pretreatment effect meets the repair requirements. The specific details are as follows: the comparison and analysis module uses advanced algorithm models to deeply compare and analyze the actual working condition parameters and the preset standard. In particular, for the high requirements of the ultraviolet light curing repair process on the state of the inner wall of the pipeline, the system will focus on evaluating the cleanliness, dryness and possible sediment residues of the inner wall of the pipeline. The system will also consider the working condition differences of different sections of the pipeline, and perform sectional and hierarchical comparison and analysis to more comprehensively reflect the overall pretreatment effect of the pipeline.

[0045] Step five, based on the comparison and analysis results, the conclusion determination module automatically determines whether the pipeline pretreatment effect is qualified, and generates a pre-inspection report containing the determination conclusion. After the pre-inspection report is fed back to the user, corresponding measures are taken for subsequent processing. The specific details are as follows: based on the results of the comparison and analysis, the conclusion determination module automatically determines whether the pipeline pretreatment effect meets the requirements of the ultraviolet light curing repair process, and generates a detailed pre-inspection report. The pre-inspection report not only contains the overall evaluation of the pipeline pretreatment effect, but also lists the existing problems, the specific section position and the suggested improvement measures, etc., providing clear guidance and reference for subsequent repair construction.

[0046] Step six, the security guarantee module is used to prevent illegal access and data tampering. The specific details are as follows: during the entire pre-inspection process, the security guarantee module is always running, ensuring the security of data transmission, the stability of system operation and the accuracy of data processing.

[0047] Therefore, the pre-inspection system for non-excavation repair of underground pipelines and the working condition determination method have obvious advantages and effects, and can ensure that the pipeline pretreatment effect meets the requirements of the repair process, providing strong guarantee for the successful implementation of repair construction.

[0048] It should be pointed out finally that the above examples are only used to illustrate the technical solutions of the present application but not to limit it, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can still be modified or replaced equivalently, and these modifications or equivalent replacements should not make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present application.
