Description

Technical Field

[0001] The present invention relates to the technical field of waterproof detection of directly buried pipes, and particularly to a method for detecting the waterproof performance of foam glass for directly buried pipes. Background Art

[0002] As an inorganic non-metallic material mainly made of waste glass, foam glass has the characteristics of light weight, high strength, excellent heat insulation performance, fire resistance and corrosion resistance, and is widely used in building energy conservation and directly buried pipeline projects. Its closed-cell structure endows good moisture barrier performance. However, directly buried pipes need to bear complex working conditions such as soil load, groundwater seepage, and temperature and humidity changes. Therefore, the detection of the waterproof performance of foam glass is particularly important.

[0003] The traditional method for detecting the waterproof performance of foam glass for directly buried pipes conducts tests on the pre-treated directly buried pipes through buried tests and water immersion tests. However, during the tests, after the test directly buried pipes are landfilled or immersed in water, it is necessary to manually adjust the test environment by adding weight to the landfill layer and agitating the static water to simulate the complex underground soil environment and water dynamic pressure. The simulation effect is poor, time-consuming and laborious, and the data of the simulation test depends on manual collation and is relatively fuzzy, with low reference value.

[0012] Step 2: Conduct a waterproof performance test in the test simulation block and perform test execution control on the waterproof performance test.

[0013] As a further improvement of the present invention, the test execution control is specifically:

When the waterproof performance test corresponds to the buried soil test, generate a test signal SY 土 , detect the test simulation box in the test simulation device. When the test simulation box corresponds to the soil simulation chamber, generate the corresponding simulation chamber signal MN 土 ; When the test simulation box corresponds to the water immersion simulation chamber, generate the corresponding simulation chamber signal MN 水 ; Match the test signal with the simulation chamber signal to obtain the matching signal (SY n , MN n ). When the matching signal corresponds to (SY 土 , MN 土 ), it indicates that the waterproof performance test is matched and generate a test run signal. When the matching signal corresponds to (SY 土 , MN 水 ) or there is no simulation chamber signal, it represents that the waterproof performance test is not matched and generate a test run delay signal;

[0016] Test execution stage: When detecting the test permit instruction, specifically execute the waterproof performance test. Among them, the buried soil test is specifically as follows: Place the test pipe sample on the Y-shaped object placing rod in the test simulation box and fill and level the soil. Drive the positioning frame to descend through the simulation box positioning cylinder, and fix the test simulation box through the guidance of the arc-shaped positioning groove A and the arc-shaped positioning groove B. Drive the pressure loading plate to descend through the hydraulic servo system in the pressure loading component to perform soil pressurization operation on the soil. Through the centrifugal water pump pressurization system, inject the test water with a preset temperature from the external constant temperature water tank into the test simulation box through the water outlets of the shunt component to increase the soil humidity, and the excess test water will be discharged through the drainage port preset on the equipment main body;

When the fault warning signal corresponds to no fault, mark the corresponding test data as preferred test data, and mark the corresponding test pipe sample as a preferred test pipe sample; when the fault warning signal corresponds to a fault, mark the corresponding test data as abnormal test data, and mark the corresponding test pipe sample as an abnormal test pipe sample; perform Step 4 on the preferred test pipe sample, and perform Step 5 on the preferred test data, abnormal test data, and abnormal test pipe samples.

[0021] Divide to obtain multiple monitoring time points according to a preset time interval, obtain the pressure data of the pressure loading component based on the test data, and the pressure data includes the hydraulic system pressure and the centrifugal pump outlet pressure; calculate the standard deviation of the hydraulic pressure σ of the hydraulic system pressure corresponding to each detection time point 液压 and the average value of the hydraulic pressure μ 液压 , through the pressure fluctuation coefficient calculation formula calculate to obtain the hydraulic pressure fluctuation coefficient F 液压 ; similarly, obtain the centrifugal pressure fluctuation coefficient F corresponding to the centrifugal pump outlet pressure 离心 ; compare both the hydraulic pressure fluctuation coefficient and the centrifugal pressure fluctuation coefficient with the corresponding preset fluctuation standard coefficients to obtain pressure qualification information. When both the hydraulic pressure fluctuation coefficient and the centrifugal pressure fluctuation coefficient are within the fluctuation standard coefficients, output pressure qualification information, otherwise output pressure abnormality information.

[0022] Based on the test data, the temperature data and humidity data inside the test simulation device are obtained. Based on the temperature data, the maximum temperature and the minimum temperature in the corresponding time period of adjacent monitoring time points are obtained. The temperature maximum value and the temperature minimum value are subtracted by a subtractor to calculate the temperature fluctuation value. When the temperature fluctuation value is greater than the 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 is greater than the preset threshold, a humidity anomaly signal is output; when a temperature anomaly signal or a humidity anomaly signal is detected, temperature and humidity anomaly information is generated; the pressure anomaly information and the fault warning signal corresponding to the temperature and humidity anomaly information are considered to be faulty.

[0023] Step 4: Transport the preferred test tube sample to the sample disassembly block for disassembly. Data collection of the transportation and disassembly process of the preferred test tube sample is carried out through a high-definition camera component to obtain disassembly data and test record data; the disassembly data is analyzed by a preset disassembly monitoring unit to obtain disassembly compliance. When the disassembly compliance corresponds to abnormal disassembly specifications, the corresponding test record data is marked as problematic test data; on the contrary, when the disassembly compliance corresponds to normal disassembly specifications, the corresponding test record data is marked as compliant test data, and step 5 is performed on the compliant test data.

[0024] As a further improvement of the present invention, the disassembly monitoring unit, its specific analysis method is:

[0025] Based on the disassembly data, the actual trajectory coordinates (x i , y i ) corresponding to multiple sampling points of the disassembly are obtained. The preset trajectory coordinates (x i0 , y i0 ) preset in the database are obtained. The path deviation rate PC is calculated through the path deviation calculation formula ; where n represents the number of sampling points, and L represents the total length of the preset path; the number of frames corresponding to the disassembly video is obtained according to the disassembly data, and multiple key frames are extracted at a preset inter-frame interval time. The disassembly images of adjacent key frames are compared to obtain the displacement between adjacent frames. The adjacent frame displacement and the inter-frame interval time are ratio-calculated through the speed calculation formula to obtain the disassembly speed;

[0026] The preset path deviation threshold and disassembly speed threshold designed in advance are obtained, and the path deviation rate and disassembly speed are monitored 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, the corresponding disassembly compliance is generated as abnormal disassembly specifications.

[0027] Step 5: Generate test data reports corresponding to the preferred test data, abnormal test data, abnormal test tube samples, and compliant test data.
