Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a rapid detection device for the compaction quality of rockfill bodies. Background Technology

[0002] In the field of hydraulic engineering, concrete-faced rockfill dams are an important type of dam with unique and complex structural characteristics. They are primarily constructed from rockfill masses with an extremely wide range of particle sizes, ranging from fine gravel to massive boulders. This non-uniformity in particle size presents significant challenges to the construction of the rockfill mass, but it is precisely this characteristic that allows concrete-faced rockfill dams to possess a certain level of strength and stability while adapting to diverse geological conditions and engineering requirements.

[0003] Compaction is a crucial step in the construction of rockfill dams. Proper compaction techniques ensure a tighter bond between rock particles, increasing the density and overall strength of the dam, thus guaranteeing its safety and stability. However, simply compacting the rockfill is insufficient. To ensure the dam meets design requirements and relevant standards, comprehensive and meticulous quality testing is essential after compaction. This testing typically includes assessing multiple indicators such as density, porosity, and particle size distribution. Only through rigorous quality inspection can potential problems during the rockfill construction process be identified and addressed, ensuring the safe operation of concrete-faced rockfill dams.

[0032] This invention provides a rapid testing device for the compaction quality of rockfill. By pre-embedding transparent pipes, a convenient channel is provided for the first camera to directly enter the rockfill for testing. The first camera can clearly capture the particle distribution and density within the rockfill, allowing inspectors to visually understand the compaction status and identify potential problems such as uneven compaction and excessive porosity, thus assessing the compaction quality. Simultaneously, multiple earth pressure sensors are connected at intervals to the outer wall of each transparent pipe. These sensors accurately measure earth pressure data at different locations within the rockfill in real time. An earth pressure data acquisition unit receives the earth pressure data transmitted from the sensors. By analyzing the changes in earth pressure data, the compaction degree and stress distribution of the rockfill at different compaction stages can be understood, providing crucial information for assessing the compaction quality.

[0033] By comprehensively analyzing earth pressure data and images captured by the first camera, the compaction degree, dry density, and particle distribution of the rockfill after compaction can be simultaneously detected, allowing inspectors to comprehensively and accurately assess the compaction quality of the rockfill. Compared with traditional detection methods, this device has the following significant advantages: First, it is fast, enabling the detection of the compaction quality of the rockfill in a short time, greatly improving detection efficiency; second, the detection results are intuitive and accurate, allowing direct observation of the compaction status inside the rockfill through the captured images, avoiding errors caused by sampling in traditional methods; third, it is simple to operate, with a high degree of automation, reducing the tediousness and errors of manual operation.

[0034] Because the earth pressure sensor is pre-embedded inside the paved rockfill along with the transparent conduit, data acquisition using the earth pressure sensor and the first camera will not disturb or damage the rockfill, allowing for direct measurement of the compaction quality of the rockfill. Furthermore, the multiple transparent conduits pre-embedded at intervals within the paved rockfill ensure that the detection range covers the entire rockfill, reflecting the overall compaction quality and improving detection accuracy.

Detailed Implementation

[0042] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The inventors discovered that the commonly used quality monitoring method in engineering is the pit-filling water method. This method is time-consuming, inefficient, and severely impacts construction progress. Furthermore, the pit-filling water method can only be used to detect certain points, employing a "point-to-surface" approach to reflect the compaction quality of the entire rockfill, which has limitations. Other detection methods mainly rely on ground-penetrating radar and shock wave detection. While these methods have a large detection range, their accuracy is low and errors are significant. Currently, they are still in the research stage and have not been directly applied to the detection of rockfill structures.

[0046] The small particle size in the rockfill is less than 0.075 mm, while the large particle size is 80 cm or even larger, with a particle size difference of more than 10,000 times. Due to the presence of large particles, it is impossible to directly detect them using the penetration method. Using the pit digging and water filling method or core drilling sampling will cause varying degrees of disturbance and damage to the rockfill.

[0047] To address the aforementioned issues, the inventors developed a rapid testing device for the compaction quality of rockfill. This device does not disturb or damage the rockfill and can directly measure its compaction quality. The testing range covers the entire rockfill, reflecting the overall compaction quality and improving testing accuracy. Example

[0048] See Figure 1 and Figure 2This embodiment proposes a rapid detection device for the compaction quality of rockfill. The device includes multiple earth pressure sensors 1, multiple transparent pipes 2, a first camera 3, a detection housing 4, an earth pressure data acquisition unit 5 located within the detection housing 4, and a lifting mechanism 6. The multiple transparent pipes 2 are pre-embedded at intervals inside the paved rockfill, with the bottom end of each pipe fixed to the bottom of the rockfill and the top end extending beyond the surface of the rockfill. The lifting mechanism 6 is connected to the first camera 3. When it is necessary to photograph the interior of the rockfill, the lifting mechanism 6 drives the first camera 3 to enter through the top end of any transparent pipe 2, and photograph the interior of the paved rockfill along the transparent pipe 2. (See reference...) Figure 2 Each transparent pipe 2 has multiple earth pressure sensors 1 connected at intervals on its outer wall. These earth pressure sensors 1 are characterized by high precision and high sensitivity, and can measure earth pressure data at different locations inside the rockfill in real time and accurately. The earth pressure data acquisition device 5 is wirelessly connected to all the earth pressure sensors 1 and transmits the earth pressure data measured by the earth pressure sensors 1 to the earth pressure data acquisition device 5 in a timely manner.

[0049] In this embodiment, the transparent pipe 2 is made of a high-strength, high-transparency material, such as polycarbonate (PC), to ensure clear observation of the pipe's interior while withstanding the pressure of the rockfill. The pre-embedded transparent pipe 2 provides a convenient channel for the first camera 3 to perform its inspection work, allowing the camera 3 to directly enter the rockfill for inspection. The length of the transparent pipe 2 can be flexibly customized according to the preset thickness of the fill layer, and different numbers of transparent pipes 2 can be buried depending on the size of the rockfill compaction area. When pre-embedding the transparent pipe 2, it is sufficient that the transparent pipe 2 remains generally vertical, allowing for some horizontal deviation. (See reference...) Figure 2 A soil pressure sensor 1 can be arranged at 50cm intervals on the outer wall of the transparent pipe 2. The soil pressure sensor 1 and the transparent pipe 2 can be connected using existing components such as wire 11 and cable ties. The soil pressure sensor 1 can collect the changes in soil pressure during the filling process, reflecting the compaction state of the rockfill. The dry density of the rockfill can be calculated based on the maximum dry density.

[0050] In this embodiment, the earth pressure data acquisition device 5 receives the internal earth pressure data of the rockfill transmitted by the earth pressure sensor 1 and processes and analyzes this data in real time. The earth pressure data acquisition device 5 can display the acquired data intuitively in the form of charts, curves, etc., which is convenient for inspection personnel to observe and analyze. At the same time, it can also store the data in its internal memory for subsequent query and further analysis. Based on the acquired earth pressure data, by analyzing the changes in earth pressure data, the compaction degree and stress distribution of the rockfill at different rolling stages can be understood, providing an important basis for evaluating the rolling quality. Furthermore, by using the earth pressure sensor 1 to collect earth pressure data before and after rolling the rockfill, the internal compaction degree of the rockfill can be obtained; by combining the earth pressure data before and after rolling and the obtained maximum dry density (which can be obtained by indoor compaction test of the rockfill), the maximum dry density of the rockfill after rolling can be calculated. Meanwhile, the first camera 3 has high-definition shooting capabilities, which can clearly capture the particle distribution and density inside the rockfill. Inspectors can intuitively understand the compaction status inside the rockfill and discover potential problems such as uneven compaction and excessively large pores, so as to further evaluate the compaction quality.

[0051] By comprehensively analyzing earth pressure data and images captured by the first camera 3, the compaction degree, dry density, and particle distribution of the rockfill after compaction can be simultaneously detected, enabling inspectors to comprehensively and accurately assess the compaction quality of the rockfill. Compared with traditional detection methods, this device has the following significant advantages: First, it is fast, capable of completing the detection of the compaction quality of the rockfill in a short time, greatly improving detection efficiency; second, the detection results are intuitive and accurate, allowing direct observation of the compaction status inside the rockfill through the captured images, avoiding errors caused by sampling in traditional methods; third, it is simple to operate, with a high degree of automation, reducing the tediousness and errors of manual operation.

[0052] In this embodiment, since the earth pressure sensor 1 is pre-embedded inside the paved rockfill along with the transparent pipe 2, the data acquisition using the earth pressure sensor 1 and the first camera 3 will not disturb or damage the rockfill, allowing for direct measurement of the compaction quality of the rockfill. Simultaneously, because multiple transparent pipes 2 are pre-embedded at intervals inside the paved rockfill, the detection range can cover the entire rockfill, reflecting the overall compaction quality and improving detection accuracy.

[0053] In one specific embodiment, see [reference] Figure 1A display mechanism 9 is installed on the outside of the testing box. This display mechanism 9 is connected to the first camera 3, and the images captured by the first camera 3 can be transmitted to the display mechanism 9 in real time. The display mechanism 9 is pre-installed with image recognition software. After the images captured by the first camera 3 are processed by the image recognition software, the vertical particle size distribution of the rockfill body can be formed, and the porosity distribution inside the rockfill body can be obtained. Of course, a data storage device 12 can be installed inside the testing box. This data storage device 12 is connected to the first camera 3 and can store the images captured by the first camera 3, so that the testing personnel can obtain historical data for comparative analysis of the compaction quality of the rockfill body.

[0054] In one specific embodiment, see [reference] Figure 2 Each transparent pipe 2 has an anti-slip texture (not shown in the figure) on its outer wall corresponding to the position of the earth pressure sensor 1. During the compaction of the rockfill, strong vibrations are generated. Without the anti-slip texture, the earth pressure sensor 1 may slide on the outer wall of the transparent pipe 2, causing a change in the measurement position and resulting in inaccurate earth pressure data. The anti-slip texture increases the friction between the earth pressure sensor 1 and the transparent pipe 2, effectively preventing displacement of the earth pressure sensor 1 and ensuring the accuracy and reliability of the measurement data. The presence of the anti-slip texture makes the connection between the earth pressure sensor 1 and the transparent pipe 2 tighter, reducing the shaking of the earth pressure sensor 1 caused by vibration. This helps improve the measurement stability of the earth pressure sensor 1, making the collected earth pressure data more stable and continuous, facilitating subsequent data analysis and processing. Because the anti-slip texture prevents displacement and shaking of the earth pressure sensor 1, and reduces friction and collision between the earth pressure sensor 1 and the transparent pipe 2, it reduces the risk of wear and damage to the earth pressure sensor 1, helping to extend its service life and reduce equipment maintenance costs.

[0055] In one specific embodiment, see [reference] Figure 1The lifting mechanism 6 is a key component of the device for enabling the flexible lifting and lowering of the first camera 3. The lifting mechanism 6 includes a control motor 601, a winding reel 602, and a guide cable 603. The control motor 601 is located in the detection housing 4 and can be a high-performance servo motor, characterized by fast response, high control precision, and smooth operation. The output end of the control motor 601 is connected to the winding reel 602, allowing the control motor 601 to precisely control the rotation of the winding reel 602. The winding reel 602 can be made of high-strength alloy material, possessing good wear resistance and fatigue resistance. The surface of the winding reel 602 has uniform grooves for winding the guide cable 603. The guide cable 603 is wound around the winding reel 602, and the first camera 3 is located at the end of the guide cable 603. The guide cable 603 includes an external protective sleeve and a data transmission line located inside the protective sleeve. The data transmission line is used to connect the first camera 3 and the display mechanism 9 to transmit the data of the first camera 3 to the display mechanism 9. At the same time, by setting the protective sleeve, the entire guide cable 603 has good flexibility and tensile strength, and can work stably in complex rockfill environments.

[0056] In use, the reel 602, driven by the control motor 601, can rotate in both directions, thereby raising and lowering the guide cable 603. This, in turn, controls the position of the first camera 3 within the transparent pipe 2, allowing the first camera 3 to capture omnidirectional images of the interior of the paved rockfill along the transparent pipe 2. Inspectors can directly observe the particle distribution, density, and porosity within the rockfill, providing a clear visual basis for assessing compaction quality. Simultaneously, the device boasts a high degree of automation, reducing the tediousness and errors of manual operation and avoiding potential safety risks associated with traditional inspection methods.

[0057] In one specific embodiment, see [reference] Figure 1 The lifting mechanism 6 also includes a rotary motor (not shown in the figure), which is connected to the end of the guide cable 603. The output shaft of the rotary motor is connected to the first camera 3. In use, the rotary motor rotates, driving the first camera 3 to rotate 360 ​​degrees, thereby achieving multi-angle and comprehensive imaging of the interior of the rockfill, providing more comprehensive data for evaluating the compaction quality of the rockfill.

[0058] In one specific embodiment, see [reference] Figure 1 and Figure 2The inner wall of the transparent pipe 2 is provided with a guide groove extending axially (not shown in the figure). The lifting mechanism 6 also includes a counterweight (not shown in the figure), which is connected to the bottom of the first camera 3. The counterweight is made of lead alloy material, which has a high density and can provide sufficient gravity for the first camera 3, ensuring that the first camera 3 remains stable during lifting and reducing shaking. The outer wall of the counterweight is provided with a ball bearing (not shown in the figure). The ball bearing uses high-precision steel balls and a cage, and the ball bearing can roll along the guide groove of the transparent pipe 2. The cooperation between the ball bearing and the guide groove makes the counterweight and the first camera 3 more stable and smooth during lifting and lowering. At the same time, it can prevent the first camera 3 from colliding and effectively protect the first camera 3. Under the action of the counterweight, sufficient gravity is provided for the first camera 3, which can maintain the stability of the first camera 3 during the rotation of the rotary motor, thereby ensuring the quality of the captured image and further improving the accuracy of detection.

[0059] In one specific embodiment, see [reference] Figure 1 The detection device in this embodiment also includes an adjustable-height overhead camera bracket 7 and a second camera 8. One end of the overhead camera bracket 7 is connected to the detection housing 4, and the other end is connected to the second camera 8, which can capture images of the surface of the paved rockfill. The overhead camera bracket 7 can be made of retractable aluminum alloy, and its height can be adjusted via an internal electric push rod. The electric push rod has high precision, high load capacity, and stable operating performance, allowing for precise adjustment of the height of the second camera 8 according to actual detection needs. The second camera 8 is connected to the display mechanism 9, and the images captured by the second camera 8 can be transmitted to the display mechanism 9 in real time. After processing with image recognition software, the captured images can form the surface particle size distribution of the rockfill. Inspectors can intuitively observe the flatness and particle distribution of the rockfill surface. Combined with the internal images captured by the first camera 3 and the data collected by the soil pressure sensor 1, comprehensive detection of the interior and surface of the rockfill is achieved, avoiding blind spots in traditional detection methods and enabling a comprehensive assessment of the compaction quality of the rockfill. Furthermore, by combining the vertical particle size distribution of the rockfill obtained by the first camera 3 with the surface particle size distribution of the rockfill obtained by the second camera 8 for comprehensive identification and analysis, the overall particle size distribution of the rockfill can be obtained.

[0060] In one specific embodiment, see [reference] Figure 1The bottom of the overhead camera bracket 7 is equipped with multiple high-precision laser diodes (not shown in the figure), which emit mutually perpendicular laser beams to form a uniform laser grid on the surface of the rockfill. The laser grid accurately divides the inspection area, providing precise positioning information for the surface images captured by the second camera 8. Inspectors can quickly determine the shooting position of each area based on the laser grid, avoiding repeated or missed shots and improving inspection efficiency. The laser grid has extremely high straightness and can serve as a reference benchmark for evaluating the flatness of the rockfill surface. When there are undulations on the rockfill surface, the laser grid will deform, and inspectors can visually judge the surface flatness by observing the deformation. For example, if the laser grid shows obvious bending or twisting in a certain area, it indicates that the surface flatness of that area is poor. This area can be quickly located, and corresponding data can be obtained using the first camera 3, the second camera 8, and the earth pressure sensor 1 for further analysis.

[0061] In one specific embodiment, see [reference] Figure 1 The bottom of the detection housing 4 is equipped with a movable component to improve the mobility and ease of use of the detection device in different construction scenarios. The movable component includes wheels 10 and a drive motor (not shown in the figure). The wheels 10 are rolledly connected to the detection housing 4. Specifically, the wheels 10 can be rolled to the bottom of the detection housing 4 via bearings (not shown in the figure). The bearings are high-precision deep groove ball bearings, which have advantages such as low friction coefficient, flexible rotation, and long service life, ensuring smooth rotation of the wheels 10 and reducing energy loss. The output end of the drive motor is connected to the wheels 10 to drive the movement of the movable component. The movable component enables the detection device of this embodiment to quickly reach different detection positions without manual handling or the use of other transportation tools, greatly shortening the detection time.

[0062] In one specific embodiment, see [reference] Figure 1 The testing housing 4 comprises a top frame 401, a middle frame 402, and a bottom frame 403, which are detachably connected in sequence. The top frame 401 is connected to the earth pressure data acquisition device 5, and a display mechanism 9 is installed on the outside of the top frame 401. The middle frame 402 is connected to the overhead camera bracket 7 and the second camera 8. The bottom frame 403 is connected to the lifting mechanism 6 and the first camera 3. The entire testing housing 4 forms an assembled structure that can be flexibly disassembled. It can be combined with the necessary components according to the compaction quality testing requirements of different filling sites, making it highly adaptable.

[0063] For example, when using this device for detection, the detection process may specifically include the following steps:

[0064] Step S101: During the paving of the rockfill body, multiple transparent pipes equipped with soil pressure sensors are installed.

[0065] Step S102: After the rockfill is laid, the first earth pressure data is collected using an earth pressure sensor.

[0066] Step S103: After the rock pile is compacted, a second camera is used to take pictures of the grid with a preset area as a unit.

[0067] Step S104: Lower the first camera into the transparent pipe in sequence to take multi-angle pictures of the interior of the rock pile;

[0068] Step S105: Use the earth pressure sensor to collect data for the second time, and combine the data with the first earth pressure data to obtain the compaction degree inside the rockfill.

[0069] In step S105 above, the maximum dry density of the rockfill after compaction is calculated by combining the maximum dry density obtained from the indoor compaction test of the rockfill with the first earth pressure data and the second earth pressure data.

[0070] Step S106: Use the image recognition software set in the display mechanism to recognize the images captured by the first camera and the second camera, and output the particle size distribution curve and porosity distribution of the entire rockfill body.

This disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
