Description

Technical Field

[0001] This invention relates to the field of waterproof testing technology for buried pipes, specifically a method for testing the waterproof performance of foam glass used in buried pipes. Background Technology

[0002] Foam glass, an inorganic non-metallic material made primarily from waste glass, is lightweight, high-strength, has excellent thermal insulation properties, and is fire-resistant and corrosion-resistant. It is widely used in building energy conservation and direct-buried pipeline projects. Its closed-cell structure provides good moisture-proof performance. However, direct-buried pipelines need to withstand complex conditions such as soil load, groundwater infiltration, and temperature and humidity changes. Therefore, testing the waterproof performance of foam glass is particularly important.

[0003] Traditional methods for testing the waterproof performance of directly buried pipes using foam glass involve burying and immersion tests. However, after burying or immersing the pipes, adjusting the test environment requires manual intervention, such as adding weight to the burial layer and agitating the static water, to simulate the complex underground soil environment and dynamic water pressure. This results in poor simulation effects, is time-consuming and labor-intensive, and the data from the simulation tests is often vague due to manual processing, making it less reliable for reference. Summary of the Invention

[0007] The test simulation equipment includes an installed waterproof performance testing simulation device, which comprises a test simulation chamber, a simulation box positioning component, a pressure loading component, and a monitoring and control component. The waterproof performance testing simulation device includes a main body with a sealed cabinet door hinged to the side opening. A secondary chamber is installed at the top opening of the main body, with a secondary cabinet door hinged to its top opening. A test simulation box is located inside the main body. An installation plate is fixedly installed between the inner walls of the two sides of the secondary chamber. An electrical control box is installed on the upper surface of the installation plate. The simulation box positioning component, pressure loading component, and monitoring and control component are all electrically connected to the electrical control box. An intelligent control panel is installed on the outer surface of the secondary chamber and is electrically connected to the electrical control box. Guide strips are installed on both sides of the main body, and ventilation holes are provided on both outer surfaces of the secondary chamber.

[0008] The test simulation chamber includes a soil simulation chamber and a water immersion simulation chamber. The inner wall of the soil simulation chamber is equipped with ventilation holes; the inner wall of the water immersion simulation chamber is a sealed structure with an anti-corrosion coating, and an intelligent water valve is installed on the bottom side of the chamber.

[0009] The simulation box positioning assembly includes mounting bases at all four ends of the upper surface of the main body of the equipment. The mounting bases are fixedly installed on the inner wall of the sub-box. Each mounting base has a simulation box positioning cylinder installed on its side. A positioning frame is provided on the inner side of the upper box opening of the main body of the equipment. Each simulation box positioning cylinder is fixedly connected to the upper surface of the positioning frame.

[0010] The pressure loading assembly includes a hydraulic servo system mounted on all four ends of the lower surface of the mounting plate. A pressure loading plate is installed on the upper side of the test simulation chamber, and the shape of the pressure loading plate matches the inner wall of the test simulation chamber. Sealing strips are fitted on the outer surface of the pressure loading plate, and the sealing strips fit tightly against the inner wall of the test simulation chamber. The telescopic ends of the four hydraulic servo systems are connected to the upper surface of the pressure loading plate through spherical hinges. A centrifugal water pump pressurization system is installed on the upper surface of the mounting plate. The input end of the centrifugal water pump pressurization system is connected to an external constant temperature water tank, and the output end of the centrifugal water pump pressurization system is connected to a flexible guide pipe. A diversion assembly is installed inside the pressure loading plate. The lower end of the diversion assembly has multiple water outlets, each of which extends downward and penetrates the lower surface of the pressure loading plate. The upper inlet of the diversion assembly is connected to the flexible guide pipe. The spherical hinge connection allows the pressure loading plate to adaptively tilt and pressurize according to the deformation of the soil when pressurizing the test simulation chamber, and the sealing strips increase the sealing performance.

[0011] The test simulation chamber has an arc-shaped positioning groove A on its upper end and an arc-shaped positioning groove B on the lower surface of the positioning frame. The arc-shaped positioning groove A and the positioning frame match each other. Y-shaped storage rods are installed on both sides of the lower inner wall of the test simulation chamber.

[0012] The monitoring and control components include data sensors mounted on the lower surface of the pressure loading plate, including pressure sensors and temperature and humidity sensors, and an intelligent temperature-controlled fan mounted on one side of the upper surface of the mounting plate.

[0013] Step 2: Conduct waterproof performance tests in the simulated test area and adjust the test execution.

[0014] As a further improvement to the present invention, the test execution control is specifically as follows:

[0015] Test permit preparation phase: Waterproofing performance tests include soil burial tests and water immersion tests. The waterproofing performance test is identified, and a test signal SY is generated when the corresponding waterproofing performance test is a soil burial test. 土 The test simulation chamber inside the test simulation equipment is tested. When the test simulation chamber corresponds to the soil simulation chamber, the corresponding simulation chamber signal MN is generated. 土 When the test simulation chamber corresponds to a water immersion simulation chamber, the corresponding simulation chamber signal MN is generated. 水 The test signal is matched with the simulation chamber signal to obtain the matching signal (SY). n MN n When the matching signal corresponds to (SY) 土 MN 土 When the matching signal is (SY), it indicates that the waterproof performance test is matched and a test operation signal is generated. 土 MN 水 If there is no simulation chamber signal, it indicates a mismatch in the waterproof performance test and generates a test run delay signal;

[0016] When the waterproof performance test corresponds to a water immersion test, a test signal SY is generated. 水 Similarly, when the matching signal corresponds to (SY) 水 MN 土 If there is no simulation chamber signal, it indicates a mismatch in the waterproof performance test and generates a test run delay signal; when a test run signal is detected, a corresponding test permit instruction is generated.

[0017] Test execution phase: When a test permit is detected, the waterproof performance test is carried out. The soil burial test is specifically performed as follows: the test tube sample is placed on the Y-shaped support rod inside the test simulation box and the soil is filled and leveled. The positioning frame is lowered by the positioning cylinder of the simulation box. The test simulation box is fixed by the guidance of the arc positioning groove A and arc positioning groove B. The pressure loading plate is lowered by the hydraulic servo system in the pressure loading component to pressurize the soil. The test water at the preset temperature collected by the centrifugal water pump pressurization system is injected into the test simulation box through the outlets of the diversion component to increase the soil moisture. Excess test water will be discharged through the preset drain outlet of the main body of the equipment.

[0018] The water immersion test is specifically as follows: the test tube sample is placed in the test simulation chamber and positioned by the simulation chamber positioning component. Water is injected into the test simulation chamber by the centrifugal water pump pressurization system and the liquid pressure is adjusted. The water level change in the chamber is controlled by the closing of the intelligent control water valve.

[0019] Furthermore, the number of test simulation devices within the test simulation block is identified to obtain the number of test simulation devices, Sn; when Sn=1, the soil burial test and water immersion test are performed according to the predetermined test sequence; when Sn>1, the test simulation devices are divided into two groups of test simulation devices, with the number corresponding to... The two sets of test simulation equipment were used to perform soil burial test and water immersion test respectively.

[0020] Step 3: Collect data from the simulation test using the monitoring and control components during the test execution phase. Input the test data into the fault early warning mechanism to obtain a fault early warning signal. When the fault early warning signal corresponds to no fault, mark the corresponding test data as preferred test data and the corresponding test tube sample as preferred test tube sample. When the fault early warning signal corresponds to a fault, mark the corresponding test data as abnormal test data and the corresponding test tube sample as abnormal test tube sample. Perform Step 4 on the preferred test tube sample, and perform Step 5 on the preferred test data, abnormal test data, and abnormal test tube sample.

[0021] As a further improvement of the present invention, the fault early warning mechanism specifically performs the fault early warning as follows:

[0022] Multiple monitoring time points were obtained by dividing the data into pre-set time intervals. Based on the test data, pressure data of the pressure loading component was obtained, including hydraulic system pressure and centrifugal pump outlet pressure. The standard deviation of hydraulic pressure was calculated by dividing the hydraulic system pressure at each monitoring time point. and average hydraulic pressure The formula for calculating the pressure fluctuation coefficient. The hydraulic pressure fluctuation coefficient was calculated. Similarly, the centrifugal pressure fluctuation coefficient corresponding to the centrifugal pump outlet pressure is obtained. The pressure qualification information is obtained by comparing the hydraulic pressure fluctuation coefficient and the centrifugal pressure fluctuation coefficient with the corresponding preset fluctuation standard coefficient. When both the hydraulic pressure fluctuation coefficient and the centrifugal pressure fluctuation coefficient are within the fluctuation standard coefficient, the pressure qualification information is output; otherwise, the pressure abnormality information is output.

[0023] Based on the experimental data, temperature and humidity data within the experimental simulation equipment are obtained. The maximum and minimum temperature values ​​for adjacent monitoring time points are acquired from the temperature data. A subtractor is used to calculate the difference between the maximum and minimum temperature values ​​to obtain the temperature fluctuation value. When the temperature fluctuation value exceeds a preset threshold, a temperature anomaly signal is output. Similarly, the humidity fluctuation value corresponding to the humidity data is obtained, and when the humidity fluctuation value exceeds a preset threshold, a humidity anomaly signal is output. Temperature and humidity anomaly information is generated when either a temperature or humidity anomaly signal is detected. Fault warning signals corresponding to pressure anomaly information and temperature and humidity anomaly information are identified as faulty.

[0024] Step 4: Transport the selected test tube sample to the sample disassembly area for disassembly. Use a high-definition camera to collect data on the transportation and disassembly process of the selected test tube sample to obtain disassembly data and test record data. Analyze the disassembly data through a pre-set disassembly monitoring unit to obtain disassembly compliance. When the disassembly compliance corresponds to an abnormal disassembly compliance, mark the corresponding test record data as problematic test data; conversely, when the disassembly compliance corresponds to a normal disassembly compliance, mark the corresponding test record data as compliant test data, and proceed to Step 5 for compliant test data.

[0025] As a further improvement of the present invention, the monitoring unit is disassembled, and the specific analysis method is as follows:

[0026] The actual trajectory coordinates corresponding to multiple sampling points obtained from the disassembly data are obtained. Obtain the preset trajectory coordinates from the database. Calculated using the path deviation formula The path deviation rate PC is calculated; where n represents the number of sampling points and L represents the total length of the preset path.

[0027] The number of frames corresponding to the disassembly video is obtained from the disassembly data. Multiple key frames are extracted according to the preset inter-frame interval time. The disassembly images of adjacent key frames are compared to obtain the displacement between adjacent frames. The disassembly speed is calculated by the ratio of the displacement between adjacent frames to the inter-frame interval time using the speed calculation formula.

[0028] Obtain the pre-designed path deviation threshold and disassembly speed threshold, and monitor the path deviation rate and disassembly speed in real time. When the path deviation rate is greater than the path deviation threshold or the disassembly speed is greater than the disassembly speed threshold, generate the corresponding disassembly specification as disassembly specification abnormal.

[0029] Step 5: Generate a report by combining the selected test data, abnormal test data, abnormal test samples, and compliant test data to obtain the corresponding test data report.

[0030] The beneficial effects of the technical solution provided by this invention compared with the prior art are as follows:
