Description

Technical Field

[0001] This utility model relates to the field of engineering technology for continuous compaction testing of roadbeds, and more specifically, to a soil moisture content testing system suitable for continuous compaction of roadbeds. Background Technology

[0002] In today's technologically advanced world, the use of clustered and automated compaction machinery has been vigorously developed and promoted in roadbed compaction operations to meet the needs of scientific, efficient, and automated process control for roadbed construction quality management. The soil moisture content after roller compaction is a crucial indicator of whether the compaction degree meets standards. Its measurement accuracy not only affects the roller's operation but also the quality of the compaction process and, more importantly, the safety of the entire roadbed.

[0003] Traditional methods for measuring soil moisture content typically require sampling and sending samples back to a laboratory for analysis. This approach is time-consuming, makes real-time monitoring difficult, and fails to meet the demands of modern construction for immediacy and efficiency. Therefore, it is crucial to ensure construction quality and efficiency by enabling real-time monitoring of soil moisture content after compaction and providing timely feedback to the road roller to optimize the workflow. Consequently, there is an urgent need to design a soil moisture content monitoring system suitable for continuous compaction of roadbeds to achieve real-time monitoring of soil moisture content and intelligent control of the construction process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a soil moisture content detection system suitable for continuous compaction of roadbeds. It has the advantages of improving the efficiency and accuracy of moisture content detection, ensuring the stability and accuracy of measurement data, and thus solving the problem that traditional soil moisture content measurement methods usually require sampling and sending back to the laboratory for analysis, making it difficult to achieve real-time monitoring and failing to meet the needs of modern construction for immediacy and efficiency.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned advantages of improving the efficiency and accuracy of moisture content detection, and ensuring the stability and accuracy of measurement data, the specific technical solution adopted by this utility model is as follows:

[0008] A soil moisture content detection system suitable for continuous compaction of roadbed includes a road roller body, a satellite locator installed at the top of the road roller body, a display screen installed on one side of the inner top of the road roller body, a signal analyzer installed at the bottom of the display screen, an axle support installed on the outer bottom of the road roller body, a sensor installed on one side of the top of the axle support, a pressure roller installed inside the axle support, and a moisture content detection component installed on the outer circumference of the pressure roller.

[0009] Furthermore, in order to uniformly set several sets of moisture measuring device bodies on the outer circumference of the pressure roller, and to use snap-fit ​​components to install and fix the moisture measuring device bodies, comprehensive coverage detection of the subgrade soil is achieved, ensuring the comprehensiveness and representativeness of the measurement data, significantly improving the efficiency and accuracy of moisture content detection, and thus ensuring the stability and accuracy of the measurement data. The moisture content detection component includes a mounting plate set on the outer circumference of the pressure roller, several moisture measuring device bodies are uniformly set inside the mounting plate, and snap-fit ​​components are symmetrically set on both sides of the moisture measuring device bodies. First fixing frames that cooperate with the snap-fit ​​components are symmetrically set at both ends of the moisture measuring device bodies. The moisture measuring device bodies are FDR special-shaped moisture measuring devices.

[0010] Furthermore, in order to enable independent disassembly and replacement of individual moisture measuring devices through the snap-fit ​​assembly, each moisture measuring device operates independently. When the detection effect of a certain moisture measuring device is abnormal or malfunctions, it can be disassembled and replaced individually, thereby ensuring the overall accuracy and stability of the detection system. The mounting plate has a first mounting groove inside, and several second mounting grooves that cooperate with the snap-fit ​​assembly are opened on both sides of the first mounting groove.

Detailed Implementation

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a soil moisture content detection system suitable for continuous compaction of roadbeds is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the soil moisture content detection system for continuous compaction of roadbed according to an embodiment of the present invention includes a roller body 1, a satellite locator 2 is provided at the top of the roller body 1, a display screen 3 is provided on one side of the inner top of the roller body 1, a signal analyzer 4 is provided at the bottom of the display screen 3; a wheel axle bracket 5 is provided at the outer bottom of the roller body 1, a sensor 6 is provided on one side of the top of the wheel axle bracket, a pressure roller 7 is provided inside the wheel axle bracket 5; and a moisture content detection component 8 is provided on the outer circumference of the pressure roller 7.

[0028] By using the above solution, the present invention installs the moisture content detection component 8 on the roller 7, enabling the moisture measurement device body 802 to collect soil moisture content data in real time as the roller body 1 moves, without relying on laboratory analysis, providing instant feedback. Furthermore, the moisture measurement device body 802 uses electromagnetic wave reflection technology to measure soil moisture content, eliminating the need for sampling operations, avoiding damage to the soil structure, and having minimal impact on the construction process, thereby significantly improving detection efficiency and construction quality.

[0029] Specifically, the moisture measuring device body 802 is an FDR-type moisture measuring device. The moisture measuring device body 802 sends a sweep test signal of a specific frequency band. At the conductor impedance mismatch, a strong reflected signal with the same frequency as the transmitted signal but at a different time will be generated. These signals are analyzed by Fourier transform, and the distance to the line obstacle point is calculated by measuring the frequency of the peak value of the reflected signal. Using the principle of electromagnetic pulse, the apparent dielectric constant of the soil is tested according to the propagation frequency of electromagnetic waves in the soil to obtain the volumetric water content of the soil. The probe of the moisture measuring device body 802 mainly consists of a pair of electrodes forming a capacitor, with the soil between them acting as the dielectric. The capacitor and the oscillator form a tuning circuit.

[0030] Specifically, the capacitance of sensor 6 is directly proportional to the dielectric constant of the measured medium between the two poles. When the moisture in the soil increases, its dielectric constant increases accordingly, and the measured capacitance value also rises, causing the measurement frequency to change. Thus, the soil moisture content is measured. Sensor 6 can collect data such as the number of compaction cycles, vibration frequency, and compaction speed. Signal analyzer 4 collects and processes the transmitted data and is interconnected with the satellite locator 2 installed on the top of the roller body 1. Display screen 3 provides the operator with real-time compaction data and performs process control of roadbed compaction.

[0031] Specifically, the moisture measurement device 802 integrated into the compaction machinery is used to detect the soil moisture content after compaction in real time. This data is then integrated with other information to build a wireless monitoring system for soil moisture content, number of compaction cycles, vibration frequency, and compaction speed. The data is transmitted to the display screen 3 installed in the cab. Based on the information displayed on the display screen 3, the operator controls the compaction process of the roadbed to ensure the quality of construction compaction and realize the informatization of embankment construction.

[0032] In one embodiment, the moisture content detection component 8 includes a mounting plate 801 disposed on the outer circumference of the pressure roller 7. A plurality of moisture measuring device bodies 802 are uniformly disposed inside the mounting plate 801. A snap-fit ​​component 803 is symmetrically disposed on both sides of each moisture measuring device body 802. A first fixing frame 804 cooperating with the snap-fit ​​component 803 is symmetrically disposed at both ends of each moisture measuring device body 802. Thus, a plurality of moisture measuring device bodies 802 are uniformly disposed on the outer circumference of the pressure roller 7, and the snap-fit ​​component 803 is used to install and fix the moisture measuring device bodies 802. This achieves comprehensive coverage detection of the roadbed soil, ensuring the comprehensiveness and representativeness of the measurement data, significantly improving the efficiency and accuracy of moisture content detection, and thus guaranteeing the stability and accuracy of the measurement data.

[0033] In one embodiment, for the aforementioned mounting plate 801, a first mounting groove 8011 is provided inside the mounting plate 801, and a plurality of second mounting grooves 8012 that cooperate with the snap-fit ​​assembly 803 are provided on both sides of the first mounting groove 8011. The snap-fit ​​assembly 803 includes a second fixing frame 8031 ​​disposed inside the first mounting groove 8011 and located on one side of the moisture measuring device body 802. A compression spring 8032 is disposed inside the second fixing frame 8031, and a snap-fit ​​post 8033 is disposed on the side with the compression spring 8032. A toggle plate 8034 is disposed on the outer circumference of the snap-fit ​​post 8033. One side of the second fixing frame 8031... The two sides are provided with third mounting slots 8035 that cooperate with the toggle plate 8034. The first fixing frame 804 has a first locking hole 8041 that cooperates with the locking post 8033. The second fixing frame 8031 ​​has a second locking hole 80311 that cooperates with the compression spring 8032. Thus, the locking assembly 803 can realize the independent disassembly and replacement of a single moisture measuring device body 802. Each moisture measuring device body 802 operates independently. When the detection effect of a certain moisture measuring device body 802 is abnormal or malfunctions, it can be disassembled and replaced individually, thereby ensuring the overall accuracy and stability of the detection system.

[0034] Specifically, the working principle of the snap-fit ​​assembly 803 is as follows: When fixing the moisture measuring device body 802, the actuating plate 8034 is pressed against the compression spring 8032 from inside one of the third mounting slots 8035. At the same time, the snap-fit ​​post 8033 is aligned with the first snap-fit ​​hole 8041. Thus, the rebound action of the compression spring 8032 can drive the snap-fit ​​post 8033 to be inserted into the first snap-fit ​​hole 8041, and fix the actuating plate 8034 into the other third mounting slot 8035, thereby realizing the installation and fixing of the moisture measuring device body 802.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In practical applications, the moisture measuring device body 802 is first installed in the first mounting slot 8011. The moisture measuring device body 802 is then fixed in place by the snap-fit ​​component 803. Protective measures are taken around the moisture measuring device body 802 to prevent external interference and damage. After the road roller body 1 begins construction, the moisture measuring device body 802 starts to collect the dielectric constant of the soil in real time. The data is then processed using a built-in algorithm (the core of which is based on the nonlinear relationship between the dielectric constant and soil moisture content, and uses a calibration model to convert the dielectric constant into the volumetric moisture content of the soil, combined with compensation correction). The system calculates the soil moisture content using high-precision measurement. Through a built-in wireless transmission module, the data is transmitted in real-time to the control system and signal analyzer 4. The signal analyzer 4 then performs a fitting simulation of the received raw data and combines it with other detection data to determine the compaction effect. The real-time monitoring data and results are fed back to the display screen 3. Construction personnel can accurately adjust and control the road roller body 1's travel route and compaction speed using the satellite locator 2 to ensure optimal compaction results. This achieves real-time monitoring of soil moisture content, thereby improving construction quality and efficiency and providing reliable real-time data support for the construction process.

[0037] Specifically, in the control system and signal analyzer 4, the collected moisture content data is processed, including fitting, simulation, and comprehensive analysis with other detection parameters (such as compaction degree, roadbed material density, etc.) to determine whether the compaction effect of the current rolling area meets the standard; if the effect is not ideal, the signal analyzer will combine real-time data to analyze possible reasons, such as the moisture content being too high or too low.

[0038] The processed real-time monitoring data and analysis results are fed back to display screen 3 for construction personnel to view intuitively. Display screen 3 will simultaneously display key information such as current soil moisture content, compaction degree, and construction path. At the same time, satellite locator 2 is linked with the control system to accurately determine the current position, travel route, and compaction area of ​​the road roller body 1.

[0039] Based on the real-time feedback information provided by the display screen 3 and the precise positioning data provided by the satellite locator 2, the construction personnel adjust the travel route and compaction speed of the road roller body 1 to ensure that the road roller always compacts along the optimal path and at a reasonable speed to achieve optimized compaction results.

[0040] In summary, by utilizing the above-mentioned technical solution of this utility model, the moisture content detection component 8 is installed on the roller, enabling the moisture measurement device body 802 to collect soil moisture content data in real time as the roller body 1 moves, without relying on laboratory analysis and providing immediate feedback. Furthermore, the moisture measurement device body 802 uses electromagnetic wave reflection technology to measure soil moisture content, eliminating the need for sampling operations, avoiding damage to the soil structure, and minimizing the impact on the construction process, thereby significantly improving detection efficiency and construction quality. This utility model also utilizes a plurality of moisture measurement device bodies 802 evenly arranged on the outer circumference of the roller 7, and employs… The snap-fit ​​component 803 enables the installation and fixation of the moisture measuring device body 802, thereby achieving comprehensive coverage detection of the roadbed soil, ensuring the comprehensiveness and representativeness of the measurement data, significantly improving the efficiency and accuracy of moisture content detection, and thus ensuring the stability and accuracy of the measurement data. This invention also allows for the independent disassembly and replacement of individual moisture measuring device bodies 802 through the snap-fit ​​component 803. Each moisture measuring device body 802 operates independently; when the detection effect of a particular moisture measuring device body 802 is abnormal or malfunctions, it can be disassembled and replaced individually, thereby ensuring the overall accuracy and stability of the detection system.
