Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular relates to a method for inspecting the construction quality of a water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. The quality of water conservancy projects is directly related to the safety of people's lives and property and the national economic development. With the rapid development of my country's economy, the number of water conservancy project construction projects has continued to increase, and the requirements for the quality of water conservancy project construction have become higher and higher.

[0003] At present, the traditional quality inspection method for water conservancy projects is a manual inspection method, which is measured by naked eye observation combined with measuring tools. This traditional inspection method has the following problems: First, the inspection efficiency is low. Manual inspection requires a lot of time and manpower, and the inspection results are easily affected by the subjective factors of the inspectors; second, the inspection accuracy is not high. Manual inspection is difficult to find some minor quality problems, such as cracks and leakage; third, it is difficult to achieve real-time inspection and monitoring. Manual inspection usually sets an inspection time node, and only conducts inspection when the inspection time node is reached. During the time between two inspection time nodes, inspection is usually not conducted.

[0004] Among the existing patents, the invention with application number CN202310554102.7 discloses a quality acceptance inspection method for water conservancy construction projects. The specific steps are determining the acceptance items, bringing instruments to the site, project acceptance supervision and inspection, reporting of inspection results, secondary random inspections, manual review of results, copying and archiving of results, and feedback of results. This patented solution can greatly enhance supervision through the intervention of a third party in the process of project acceptance supervision and inspection, and the entire inspection process is photographed and recorded to ensure the traceability and authenticity of the shell inspection process, prevent misreading of test values, and combine multiple manual review processes to improve the authenticity and accuracy of the data. It is convenient to assign responsibilities to individuals based on data records and seals. Combined with the secondary spot check data in the later stage, the error rate of quality acceptance inspections is reduced to a minimum.

[0005] It can be seen from the scheme and beneficial effects of the above patent that its inspection method is still the traditional inspection method of manual inspection with tools, which has failed to change the current situation of low inspection efficiency, low inspection accuracy and difficulty in achieving real-time inspection and monitoring, and needs further improvement.

[0026] Figure 2 It is a block diagram of the electrical control structure of the detection system proposed by the present invention. DETAILED DESCRIPTION

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0028] Example 1

[0029] This embodiment provides a method for inspecting the quality of water conservancy project construction. Figure 1 As shown, the following steps are included:

[0030] S100, setting up a detection system, in which the warning threshold and quality threshold of various parameters of the water conservancy project are stored, and the warning threshold and quality threshold are dynamic values ​​that change with time, and the warning threshold of the same period is less than the quality threshold of the same period. Various parameters include one or more of displacement, seepage pressure, gap and strain. When there is a parameter seepage pressure, the detection system stores a corresponding table of the warning threshold and quality threshold of the seepage pressure and different water levels. Therefore, the warning threshold and quality threshold of the seepage pressure are not only related to time, but also to the water level, and the relationship with the water level is greater after a certain period of time.

[0031] S200, sensors are provided to collect various parameters of the water conservancy project and transmit the collected data to the detection system in real time. The sensors include displacement sensors for detecting displacement parameters, seepage pressure sensors for detecting seepage pressure, crack measuring sensors for detecting gaps, and strain sensors for detecting strain. If a seepage pressure sensor for detecting seepage pressure is provided, a water level sensor for detecting water level should also be provided.

[0032] Different water conservancy projects require different types of sensors. Displacement sensors are usually used to detect the horizontal and vertical displacement of structures such as dams and sluices. For example, they are installed at key locations such as the dam crest and abutment to detect the position changes of the main structure of the water conservancy project and determine whether the structure has uneven settlement or overall displacement. If the displacement exceeds the design allowable range, it may indicate a problem with the stability of the structure. Seepage pressure sensors are mainly used to detect seepage pressure in dams, gate foundations and other parts. The seepage pressure sensor is buried inside the dam or in the dam foundation to understand the seepage situation by monitoring the pore water pressure. Once the seepage pressure increases abnormally, seepage damage such as pipe bursts and soil flow may occur, threatening the safety of water conservancy projects. Crack sensors are installed at the joints of concrete structures such as dams and sluices or at locations prone to cracks, such as the dam body joints. The changes in the width of the cracks can be accurately detected. The development of the cracks may cause the structure's impermeability to decrease and weaken the integrity of the structure. Strain sensors are arranged at key stress-bearing parts of structures such as dams and bridges, such as the main stress-bearing areas inside the dam body. It is used to measure the strain of the structure under load, and to infer the actual stress state of the structure based on the strain data to prevent the structure from being damaged due to excessive stress. Water level sensors are installed in water bodies such as reservoirs and channels to monitor water level changes in real time. Abnormal changes in water level may generate additional pressure on the structure of the water conservancy project and affect the seepage pressure.

[0033] S300: The detection system compares the parameter data collected by each sensor with the warning threshold and quality acceptance threshold of the corresponding parameter. When comparing, specific values ​​in the same period are selected for comparison.

[0034] S400, when the collected data reaches the warning threshold, the detection system sends out a warning signal to remind the staff to conduct on-site verification, which helps to conduct timely investigation when problems arise. When the collected data reaches the qualified quality threshold, the detection system sends out an alarm signal. At this time, the staff needs to conduct a detailed investigation to find out the cause, and make rectifications and repairs in time to ensure that the subsequent standards can be met and safety can be guaranteed.

[0035] S500: If the collected data is always less than the qualified quality threshold, the collected parameter data are analyzed after the test is completed to calculate the average value, standard deviation and coefficient of variation of each parameter.

[0036] S600. Based on the calculation results of the data analysis, the detection system uses the following quality evaluation formula to perform quality evaluation:

[0037]

[0038] Among them, Q represents the parameter quality evaluation index, α, β, and γ are weight coefficients, which represent the importance of the reciprocal of the standard deviation, the reciprocal of the coefficient of variation, and the average value in the quality evaluation. By adjusting these weight coefficients, the proportion of each statistical indicator in the quality evaluation can be flexibly adjusted according to different water conservancy project construction projects and different quality requirements. The value range of the weight coefficients α, β, and γ is 0≤α, β, γ≤1, and α+β+γ=1. σ represents the standard deviation, CV represents the coefficient of variation, and X represents the average value of the parameter.

[0039] The calculation formula of standard deviation σ is:

[0040]

[0041] The calculation formula of coefficient of variation CV is:

[0042]

[0043] Among them, n represents the number of data, X i Represents the i-th data.

[0044] The standard deviation reflects the degree of dispersion of the data. The smaller the standard deviation, the more concentrated the data, indicating that the quality of water conservancy project construction is more stable. Therefore, the larger the reciprocal of the standard deviation, the higher the quality evaluation index. The coefficient of variation is the ratio of the standard deviation to the mean value, which reflects the relative dispersion of the data. The smaller the coefficient of variation, the smaller the relative dispersion of the data, indicating that the quality of water conservancy project construction is more uniform. Therefore, the larger the reciprocal of the coefficient of variation, the higher the quality evaluation index. The average value of the parameter reflects the overall level of the data, and the average value can also reflect the construction quality of water conservancy projects to a certain extent.

[0045] S700, the detection system outputs the quality evaluation result, and there are multiple output methods. For example, the detection system itself has a display module, and the display module can be a display, and the detection system can display the quality evaluation result through the display. For another example, the detection system is also connected to a printing device, and the detection system can output the quality evaluation result to the printing device, and the printing device prints the quality evaluation result.

[0046] Example 2

[0047] This embodiment provides a detection system, such as Figure 2As shown, the detection system includes a main control module, a data storage module, a communication interface module, an alarm module, a display module and a wireless communication module, and the data storage module, the communication interface module, the alarm module display module and the wireless communication module are all electrically connected to the main control module. The main control module includes a data receiving unit, a data processing unit and a data drawing unit, and the dynamic early warning threshold and the qualified quality threshold are stored in the data storage module. Each sensor is connected to the data receiving unit through the communication interface module, and the data receiving unit transmits the data collected by the sensor to the data processing unit, and the data processing unit compares the data collected by the sensor with the early warning threshold and the qualified quality threshold stored in the data storage module. When the data collected by the sensor reaches the early warning threshold or reaches the qualified quality threshold, the main control module transmits a control signal to the alarm module, and the alarm module sends an early warning signal or an alarm signal according to the received control signal. The alarm module includes an on-site alarm unit and a remote alarm unit. The on-site alarm unit is an audible and visual alarm, which sends out a sound alarm signal and a light alarm signal at the same time, and has the advantage of a good alarm effect. The remote alarm unit can use a GSM alarm, which can make a call to a preset phone number inside it, and can also send abnormal data information to the preset phone number in the form of a short message.

[0048] When the sensor includes an osmotic pressure sensor for detecting seepage pressure and a water level sensor for detecting water level, the water level sensor is connected to the main control module through a communication interface module, and the data storage module stores a correspondence table of the warning threshold and quality threshold of the seepage pressure and different water levels, when the data processing unit compares the seepage pressure data collected by the sensor with the warning threshold and quality threshold of the seepage pressure stored in the data storage module, the warning threshold and quality threshold of the seepage pressure corresponding to the water level currently detected by the water level sensor are selected for comparison.

[0049] The data drawing unit of the main control module can extract the warning threshold and the qualified quality threshold stored in the storage module, and draw the warning threshold-time curve and the qualified quality threshold-time curve corresponding to the time with time as the horizontal coordinate and the threshold as the vertical coordinate, and display the above curves on the display module. After the main control module receives the data collected by each sensor, the data drawing unit draws the real-time data-time curve of each parameter with time as the horizontal coordinate and the collected value as the vertical coordinate, and displays the real-time data-time curve on the display module. The data drawing unit of the main control module merges the warning threshold-time curve, the qualified quality threshold-time curve and the real-time data-time curve of each parameter into the same value-time curve with time as the horizontal coordinate and the value as the vertical coordinate, and the three curves are displayed in different colors, and the value-time curve has the explanation of the colors corresponding to the three curves. In this way, the staff can clearly see the comparison between the existing parameter value and the warning threshold and the qualified quality threshold, which is more intuitive, and can be discovered in time when problems occur, and can accurately see the time node.

[0050] In addition, the wireless communication module of the detection system is connected to the intelligent controller, which has a display screen and an APP module. The APP module is bound to the main control module. The APP module has an input unit, a sensor data acquisition display unit and an alarm unit. The input unit is used to input parameter thresholds, perform initial threshold input or threshold modification, and transmit it to the main control module through the wireless communication module, and the main control module stores it in the data storage module. The sensor data acquisition display unit has a parameter data monitoring display page, and the value-time curve of each parameter can be viewed on the parameter data monitoring display page. When the detection system sends out an early warning signal or an alarm signal, the main control module transmits the signal to the intelligent controller through the wireless communication module, and the alarm unit of the intelligent controller sends out a corresponding early warning signal or an alarm signal. In this way, as long as the staff carries the intelligent controller, whether at work or at home, they can view the status of each parameter in real time, which helps the staff to find problems in time and effectively ensures the timeliness of the inspection.

[0051] In summary, the water conservancy project construction quality inspection method provided by the present invention can perform real-time inspection and monitoring of various parameters through sensors, and slight changes in various parameters can be reflected through the data collected by the sensors, with high inspection accuracy, and reducing the manual inspection of many projects, which not only reduces the labor intensity and manpower cost of the staff, but also effectively improves the inspection efficiency. The present invention is provided with a detection system, which can calculate the quality evaluation index according to the data collected by each sensor, realizes the digital evaluation of the quality of water conservancy project construction, provides an important basis for the reward arrangement after the project is completed, and is helpful for team management.
