Description

Technical Field

[0001] This invention belongs to the field of detection technology for earthen site protection engineering, and in particular relates to an intelligent detection device and detection method for rammed earthen site reinforcement engineering. Background Technology

[0002] The rammed earth reinforcement project is a core construction procedure for the protection of earthen sites. The thickness of the soil layer and the degree of compaction are key control indicators of the rammed earth construction quality, directly determining the density, integrity, and long-term stability of the rammed earth structure. The accuracy of their testing and the controllability of the construction process are crucial to the effectiveness of the site's protection. Currently, the testing of soil layer thickness and compaction degree in rammed earth reinforcement projects still relies on traditional manual methods: soil layer thickness and compaction thickness are measured using contact tools such as steel tape measures and measuring rods, the data is manually recorded, and then manually calculated using a calculator. The results are then used to determine whether the work is up to standard. This traditional testing method has many technical shortcomings and can no longer meet the professional requirements of rammed earth reinforcement projects. Manual measurement has large operational errors, and the accuracy of distance measurement is significantly affected by human factors, leading to large deviations in the calculation results. Too many test points increase construction costs and reduce construction progress. Manual data recording is prone to omissions and errors, and there is no systematic data storage and export function, which is not conducive to the archiving, traceability, and subsequent engineering analysis of the project testing data.

[0003] Therefore, developing an intelligent detection device and method that adapts to the requirements of earthen site protection projects and enables non-contact detection, automated calculation, real-time judgment, and on-site feedback has become the key to solving the current technical challenges. Summary of the Invention

[0004] (1) Technical problems to be solved: In view of the defects in the existing earthen site rammed reinforcement project detection, such as large human error, no real-time feedback, and uncontrollable construction quality, we provide an intelligent detection device for earthen site rammed reinforcement project, and at the same time provide a detection method based on the device to realize intelligent, automated and on-site detection, adapt to the principle of minimum intervention in earthen site protection, improve detection accuracy and construction progress, and ensure the quality of rammed construction.

[0005] (2) The technical solution adopted in this invention is as follows: A smart detection device for rammed earth archaeological site reinforcement projects includes a hardware detection module and a data processing and control module. The hardware detection module and the data processing and control module are electrically connected. The hardware detection module includes an infrared ranging unit and a power supply unit. The power supply unit supplies power to the infrared ranging unit and the data processing and control module. The data processing and control module includes a data acquisition unit, a calculation and processing unit, and a judgment and triggering unit. The data acquisition unit is used to receive data from the infrared ranging unit and transmit it to the computing unit. The processing unit has a built-in conversion algorithm for soil thickness, compaction thickness, and compaction degree, which is used to calculate the detection data of the infrared ranging unit into the measured values ​​of soil thickness, compaction thickness, and compaction degree. The determination trigger unit has built-in thresholds for soil thickness and compaction degree, which are used to compare the measured values ​​with the qualified thresholds.

[0006] A further technical solution is that the infrared ranging unit is an infrared rangefinder, and the detection end of the infrared rangefinder is equipped with a bracket.

[0007] A further technical solution is that the data processing control module also includes an audible and visual feedback unit, which includes a green light display module, a red light alarm module, and a buzzer module. The green light display module is in a constant-on mode, corresponding to the measured acceptable threshold for soil thickness and compaction degree; the red light alarm module is in a constant-on + flashing mode; and the buzzer module is in an intermittent-sounding mode, corresponding to the unacceptable threshold for measured soil thickness and compaction degree. The judgment triggering unit triggers the corresponding display mode of the audible and visual feedback unit based on the comparison result.

[0008] A further technical solution is that the conversion algorithms for soil thickness and compaction degree built into the processing unit are as follows: Soil thickness h0 = Height before soil laying p0 - Height after soil laying p1; Measured value of compaction degree h d =Compacted thickness h1 / Soil laying thickness h0, Compacted thickness h1 = Height before soil laying p0 - Height after soil laying and compaction p h The processing unit is equipped with a data storage module, which can record the measured values ​​of soil thickness, compaction thickness, compaction degree and detection time of each compaction test point, with a storage capacity of ≥10,000 sets of data.

[0009] A detection method based on an intelligent detection device for rammed earth archaeological site reinforcement projects includes the following steps: S1: Set up test points according to the construction area: area <5m² 2 At least two test points should be set up, spaced 1.0–1.5 m apart; the area should be 5–30 m². 2 Every 3m 2 No less than 1 test point; area > 30m² 2 Every 5m 2 No fewer than 1 point; all points are ≥0.2m from the edge of the site.

[0010] S2: Device debugging: Place the detection device next to the test point of the earthen site rammed earth construction, adjust the height and angle of the infrared ranging unit detection end so that the detection end is facing the rammed surface of the test point, and set the qualified threshold of soil thickness and rammed filling degree in the detection device to match the engineering design requirements. S3: Soil Laying Thickness Detection: Before laying soil at test point 1 on the rammed surface, the infrared ranging unit in the detection device detects the height p0 before soil laying. After soil laying is completed, the height p1 after soil laying is detected. The data acquisition unit transmits the detected data to the processing unit to obtain the measured value of the soil laying thickness h0 and stores it. S4: Soil thickness judgment and feedback: The judgment trigger unit compares the measured value of soil thickness h0 with the preset qualified threshold. If the measured value of soil thickness h0 does not exceed the qualified threshold ±1cm, the soil at the test point is judged to be qualified. If the measured value of soil thickness h0 exceeds the qualified threshold ±1cm, an audible and visual alarm is triggered to judge that the soil thickness at the test point is unqualified. The area around the test point needs to be leveled and tested again until the measured value of soil thickness h0 reaches the qualified threshold before proceeding to the next process of compaction. S5: Compaction Degree Detection: After compaction is completed, the infrared ranging unit detects the height data of the test points to obtain the height p after soil compaction. h The data acquisition unit transmits the detected data to the processing unit, which calculates the compaction thickness. Based on the internal substitution calculation algorithm, the processing unit automatically calculates the compaction degree h from the soil thickness and compaction thickness data. d Measured value; S6: Real-time Judgment and Feedback of Compaction Degree: The judgment trigger unit will determine the compaction degree h. d The measured value is compared with the preset qualified threshold. If the measured value is less than or equal to the qualified threshold, the test point is deemed to be qualified; if the measured value is greater than the qualified threshold, the test point is deemed to be unqualified. S7: Closed-loop construction process: If the test point compaction is qualified, the next layer of test compaction can proceed directly; if the test point compaction is unqualified, subsequent procedures are stopped, and the area around the test point is compacted. After completion, steps S5-S6 are repeated until the measured compaction degree reaches the qualified threshold. S8: Data Export and Archiving: After construction is completed, the test data in the data storage module is exported through the data transmission interface of the data processing control module to complete the archiving and retention of the engineering test data.

[0011] A further technical solution is that, in step S2, the vertical distance between the detection end of the infrared ranging unit and the test point on the rammed surface is 2.0m to 5.0m, so as to avoid collision and disturbance to the detection end during construction.

[0012] A further technical solution is that, in step S7, the construction parameters during the additional compaction are consistent with those of the previous compaction, including the weight of the tamping hammer, the number of tamping points, and the drop distance of the tamping hammer. Timely additional compaction ensures the structural uniformity of the rammed earth structure of the site.

[0013] A further technical solution is that the determination triggering unit is equipped with a threshold adjustment module, which can manually adjust the soil thickness threshold range to the design soil thickness ±1cm according to the design requirements of the earthen site ramming reinforcement project; the qualified ramming degree threshold adjustment range is 0.5~0.8.

[0014] (3) Due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Employing non-contact infrared ranging technology, the ranging accuracy is ≤±1mm, far exceeding the accuracy of traditional manual measurement. It strictly adheres to the core principle of minimal intervention in the protection of earthen sites and is suitable for the professional requirements of earthen site cultural relic protection; 2. It achieves full automation and real-time processing of the detection-calculation-judgment-feedback process. The overall time from data acquisition to audio-visual feedback is ≤5 seconds, eliminating the need for manual recording and calculation. This completely solves the shortcomings of traditional detection methods, and the detection results can guide construction in real time, significantly improving construction progress. 3. A closed-loop on-site management system was established, encompassing testing, judgment, construction correction, and process coordination. Through multiple feedback mechanisms including red light alarms and buzzers, it ensures timely correction of unqualified test points, preventing them from proceeding to the next stage. This achieves full control over the rammed earth construction quality and effectively improves the overall construction quality of the earthen site rammed earth reinforcement project. 4. The device has a high degree of integration and is easy to operate. The hardware module and data processing module are integrated into one design. The outer shell is waterproof and dustproof, making it suitable for the complex outdoor construction environment of earthen sites. The operation button area and data display screen are intuitive and easy to understand, and construction personnel can quickly get started without professional training. 5. It features adjustable thresholds, storable data, and exportable results. The threshold adjustment module can adapt to the design requirements of different earthwork rammed earth projects, the data storage module can record ≥10,000 sets of data, and the data transmission interface supports data export and archiving, facilitating project quality acceptance and subsequent data traceability, and meeting the standardized requirements of engineering testing; 6. The power supply unit uses a rechargeable lithium battery pack with a battery life of ≥8 hours. It is equipped with a power display and overcharge protection module, making it suitable for outdoor construction scenarios of earthen ruins without external power supply. The device has low energy consumption and low maintenance costs, and has good industrial application value and promotion prospects. Attached Figure Description

The trigger unit has built-in thresholds for soil thickness and compaction degree to determine whether the measured values ​​are within acceptable limits.

[0018] The infrared ranging unit is a high-precision infrared rangefinder, and the detection end of the infrared rangefinder is equipped with a bracket.

The red light alarm module is in a constant-on + flashing mode, and the buzzer module is in an intermittent-sounding mode, corresponding to the measured unacceptable threshold for soil thickness and compaction. The judgment triggering unit triggers the corresponding display mode of the audible and visual feedback unit based on the comparison result.

[0020] The built-in algorithms for converting soil thickness and compaction degree in the processing unit are as follows: Soil thickness h0 = Height before soil laying p0 - Height after soil laying p1; Measured compaction degree h d =Compacted thickness h1 / Soil laying thickness h0, Compacted thickness h1 = Height before soil laying p0 - Height after soil laying and compaction p h The processing unit is equipped with a data storage module, which can record the measured values ​​of soil thickness, compaction thickness, compaction degree and detection time of each compaction test point, with a storage capacity of ≥10,000 sets of data.

[0021] The data acquisition unit, processing unit, and triggering unit utilize existing automated control equipment and computer equipment.

[0022] A detection method based on an intelligent detection device for rammed earth archaeological site reinforcement projects includes the following steps: S1: Set up test points according to the construction area: area <5m² 2 At least two test points should be set up, spaced 1.0–1.5 m apart; the area should be 5–30 m². 2 , every 3m 2 No less than 1 test point; area > 30m²2 Every 5m 2 No fewer than 1 point; all points are ≥0.2m from the edge of the site.

[0023] S2: Device debugging: Place the detection device next to the test point of the earthen site rammed earth construction, adjust the height and angle of the infrared ranging unit detection end so that the detection end is facing the rammed surface of the test point, and set the qualified threshold of soil thickness and rammed filling degree in the detection device to match the engineering design requirements. S3: Soil Laying Thickness Detection: Before laying soil at test point 1 on the rammed surface, the infrared ranging unit in the detection device detects the height p0 before soil laying. After soil laying is completed, the height p1 after soil laying is detected. The data acquisition unit transmits the detected data to the processing unit to obtain the measured value of the soil laying thickness h0 and stores it. S4: Soil thickness judgment and feedback: The judgment trigger unit compares the measured value of soil thickness h0 with the preset qualified threshold. If the measured value of soil thickness h0 does not exceed the qualified threshold ±1cm, the soil at the test point is judged to be qualified. If the measured value of soil thickness h0 exceeds the qualified threshold ±1cm, an audible and visual alarm is triggered to determine that the soil thickness at the test point is unqualified. The area around the test point needs to be leveled and tested again until the measured value of soil thickness h0 reaches the qualified threshold before proceeding to the next step of compaction. S5: Compaction Degree Detection: After compaction is completed, the infrared ranging unit detects the height data of the test points to obtain the height p after soil compaction. h The data acquisition unit transmits the detected data to the processing unit, which calculates the compaction thickness. Based on the internal substitution calculation algorithm, the processing unit automatically calculates the compaction degree h from the soil thickness and compaction thickness data. d Measured value; S6: Real-time Judgment and Feedback of Compaction Degree: The judgment trigger unit will determine the compaction degree h. d The measured value is compared with the preset qualified threshold. If the measured value is less than or equal to the qualified threshold, the test point is deemed to be qualified; if the measured value is greater than the qualified threshold, the test point is deemed to be unqualified. S7: Closed-loop construction process: If the test point is compacted to a satisfactory level, the next layer of test compaction can proceed directly; if the test point is compacted to a substandard level, the subsequent procedures are stopped, and the area around the test point is compacted again. After completion, steps S5 to S6 are repeated until the measured compaction degree reaches the acceptable threshold. (The construction parameters for the supplementary compaction are the same as those for the previous compaction, including the weight of the hammer, the number of impact points, and the hammer drop distance. Timely supplementary compaction ensures the structural uniformity of the rammed earth structure of the site.) S8: Data Export and Archiving: After construction is completed, the test data in the data storage module is exported through the data transmission interface of the data processing control module to complete the archiving and retention of the engineering test data.

[0024] In step S2, the vertical distance between the detection end of the infrared ranging unit and the test point on the rammed surface is 2.0m to 5.0m to avoid collision and disturbance to the detection end during construction.

[0025] In step S7, the construction parameters for the supplementary compaction are the same as those for the previous compaction, including the weight of the tamping hammer, the number of tamping points, and the drop distance of the tamping hammer. Timely supplementary compaction ensures the structural uniformity of the rammed earth structure of the site.

[0026] The trigger unit is equipped with a threshold adjustment module, which can manually adjust the soil thickness threshold range to ±1cm according to the design requirements of the earthen site rammed reinforcement project; the qualified compaction degree threshold adjustment range is 0.5~0.8.

[0027] The hardware detection module and data processing control module are integrated into a waterproof and dustproof housing with a protection rating of >IP65. The housing surface is equipped with an operation button area and a data display screen. The operation button area includes a power button, a detection button, a storage button, and a threshold adjustment button. The data display screen displays the measured values ​​of the number of compaction layers, soil thickness, compaction thickness, and compaction degree in real time.

[0028] Example 1: This embodiment demonstrates intelligent detection for a reinforcement project of a loess rammed earth site, with a design compaction degree ≥0.96.

[0029] According to field tests, the optimum moisture content of the soil used for construction is 18.0%. When the soil thickness is 160mm, using 3... # When the compaction degree is ≤0.56 after 6 passes with a tamping hammer (4.5kg), the compaction degree is ≥0.96 after sampling with a ring cutter. The intelligent detection device and method of this invention are used for construction testing.

[0030] 1. Test points were set up according to the construction area. The construction surface is 0.9m wide and 6.2m long. Five test points were set up at 1.0m intervals. All test points were arranged in a curved shape and were located 0.2m to 0.4m from the edge of the site. The detection device was placed next to the test point of the earthen site. The fixed bracket of the infrared ranging unit was adjusted so that the vertical distance between the detection end and the rammed surface was about 3m, facing the rammed surface of the test point. Each infrared tester was connected to the data acquisition system. The wiring layout did not hinder the construction.

[0031] 2. Device debugging: Turn on the lithium battery power supply unit. The power display shows 100%. Use the threshold adjustment key to set the qualified threshold for soil thickness to 150-170mm and the qualified threshold for compaction degree to ≤0.56. Check that each module is operating normally, the infrared tester measuring points are in accordance with the layout, the red and green lights are both off, and the buzzer does not sound.

[0032] 3. Soil Laying Thickness Detection: Press the pre-laying acquisition key p0 on the operation button area to collect pre-laying data C1-p0~C5-1p0 (2920mm, 2911mm, 2893mm, 2841mm, 3040mm). After laying the soil, press the post-laying acquisition key p1 on the operation button area. The infrared ranging unit will collect post-laying data C1-1p1~C5-1p1 at the test points (2759mm, 2750mm, 2733mm, 2682mm, 2878mm). The infrared ranging unit will transmit the collected data to the processing unit. Press the detection key h0 on the operation button area. The data display screen will show the soil laying thickness values ​​C1-1h0~C5-1h0 at each point (161mm, 161mm, 160mm, 159mm, 162mm, where C1 represents test point #1, -1 represents the first layer, and h0 represents the soil laying thickness). 4. Soil thickness judgment and feedback: The judgment trigger unit compares the measured value of the soil thickness with the preset qualified threshold. The green light display module of the sound and light feedback unit is constantly lit, and there is no alarm when the red light is off. The soil at the test point is judged to be qualified and the next process of compaction is started. 5. Compacted Thickness Detection: After compaction, press the "ph" key in the operation button area. The infrared ranging unit will then collect the compacted data C1-1p from the test point again. h ~C5-1p h The values ​​are (2830mm, 2821mm, 2803mm, 2753mm, 2949mm), respectively. The data is transmitted from the data acquisition unit to the processing unit. When the detection key h1 is pressed, the processing unit calculates the compaction thickness as C1-1h1~C5-1h1, which are (90mm, 90mm, 90mm, 90mm, 91mm, where C1 represents test point #1, -1 represents the first layer, and h1 represents the compaction thickness).

[0033] 6. Automatic Conversion of Compaction Degree: Next, press the detection key "hd" in the operation button area. The processing unit will automatically calculate the soil thickness and compaction thickness data into the measured compaction degree value "h" according to the internal conversion algorithm. d The data display screen shows the compaction degree values ​​C1-1h at each point in real time. d ~C5-1h d The values ​​are (0.56, 0.56, 0.56, 0.55, 0.56, C1 represents test point #1, -1 represents the first layer, h) d (Indicates the degree of compaction); 7. Real-time compaction degree judgment and feedback: The judgment trigger unit compares the measured compaction degree with the preset qualified threshold. If the measured value is equal to the qualified threshold, the green light display module of the audible and visual feedback unit will remain lit, indicating that the compaction at each test point is qualified. 8. Closed-loop construction process: After the test point is successfully compacted, the next layer's compaction and testing will proceed directly. The data processing system will automatically default to the final data C1-1p from the next layer. h ~C5-1p h This refers to the data from the previous layer, C1-2p0 to C5-2p0, and so on. S8: Data Export and Archiving: After construction is completed, data is exported and archived via the data transmission interface of the data processing control module. Export the test data from the data storage module to complete the archiving and retention of the engineering test data.

[0034] Table 1. Test data for the first and second layers of rammed earth construction. In this embodiment, the device operates stably throughout the process, with a lithium battery life of up to 9 hours, meeting the construction requirements; unqualified test points are quickly corrected through real-time feedback and do not proceed to the next process, improving the overall construction efficiency by 50% compared to traditional testing methods. The compaction degree is ≥0.96 through ring sample testing, which meets the design requirements, and the accuracy of the test data is ≤±1mm, which is far higher than the accuracy of traditional manual measurement.
