Since water infiltration can cause a decrease in the strength and deterioration of the subgrade materials' bearing capacity, improper permeability control will directly lead to defects such as rutting and cracking in the pavement structure. Therefore, subgrade permeability testing is a crucial aspect of road engineering quality control.

[0027] According to an embodiment of the present invention, a seepage detection device for roadbeds is provided.
[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the roadbed seepage detection device according to an embodiment of the present utility model includes a base plate 1, a through hole 2 at the top center of the base plate 1, an angle adjustment component 3 at the top of the through hole 2, a horizontal adjustment component 4 on one side of the top of the angle adjustment component 3, a measuring cylinder 5 at the top center of the top of the angle adjustment component 3, a water guide pipe 6 at the top of the measuring cylinder 5, a water storage tank 7 on one side of the top of the base plate 1, and a water pump 8 connected to the water guide pipe 6 at the top of the water storage tank 7; a height adjustment component 9 that cooperates with the through hole 2 is provided at the bottom center of the base plate 1, universal wheels 10 are symmetrically arranged on one side of the bottom of the base plate 1, and wheels 11 are symmetrically arranged on the other side of the bottom of the base plate 1.
[0029] By utilizing the above-described technical solution of this utility model, the angle adjustment component 3 and the level adjustment component 4 work together to automatically adjust the angle of the measuring cylinder 5 to adapt to the actual slope of the roadbed, ensuring that the measuring cylinder 5 always remains horizontal. This effectively avoids measurement errors caused by tilting and significantly improves the accuracy and reliability of the roadbed permeability assessment. By setting the height adjustment component 9, the sealing ring 904 can be precisely fitted to the roadbed surface, which not only enhances the sealing performance at the contact point between the detection device and the roadbed surface, effectively preventing water leakage in non-target areas, but also significantly improves the accuracy of the detection results.
[0030] In one embodiment, for the base plate 1, a push rod 12 is provided on the other side of the top of the base plate 1, and a controller 13 is provided between the push rod 12 and the angle adjustment component 3; a photoelectric sensor 14 is provided on the side of the water tank 7 near the angle adjustment component 3, thereby increasing the functionality of the detection device and realizing automated operation.
[0031] In one embodiment, the measuring cylinder 5 is provided with a float 15 inside, which makes it easier for staff to read the test results and improves work efficiency.
[0032] In one embodiment, the angle adjustment component 3 includes a flexible tube 301 disposed at the top of the through hole 2. An adjustment plate 302 is disposed at the top of the outer circumference of the flexible tube 301, and the adjustment plate 302 cooperates with the base plate 1 through two sets of adjustment members 303. Each adjustment member 303 includes a mounting base 3031 disposed at the top of the base plate 1. Limiting blocks 3032 are symmetrically disposed at the top of the mounting base 3031, and a groove 3033 is formed at the inner bottom end of the mounting base 3031. The measuring cylinder 33 is internally equipped with a worm gear 3034, and a motor 3035 is installed at one end of the worm gear 3034. The top of the mounting base 3031 is equipped with an arc-shaped moving seat 3036 connected to the adjusting plate 302. The bottom of the arc-shaped moving seat 3036 is provided with a limiting groove 3037 that cooperates with the limiting block 3032. The inner top of the arc-shaped moving seat 3036 is provided with an arc-shaped worm wheel 3038 that meshes with the worm gear 3034, thereby realizing the angle adjustment of the measuring cylinder 5 and improving the adaptability and flexibility of the detection device.
[0033] In one embodiment, the horizontal adjustment component 4 includes a fixing block 401 disposed on one side of the top of the adjustment plate 302, and a bubble tube 402 is disposed on the inner top of the fixing block 401, so that the measuring cylinder 5 is in a horizontal position, thereby improving the accuracy of the test results.
[0034] The working principle of the angle adjustment component 3 and the level adjustment component 4 is as follows: According to the actual slope of the roadbed, the operator starts the motor 3035 through the controller 13, causing the worm gear 3034 to rotate. Due to the engagement of the arc-shaped worm wheel 3038 with the worm gear 3034, and under the synergistic action of the limiting block 3032 and the limiting groove 3037, the angle of the adjustment plate 302 is adjusted. At the same time, the photoelectric sensor 14 (for example, the above-mentioned photoelectric sensor 14 can be the EE-SX671 model, FU-7FZ model, etc.) is used to monitor the position of the bubble in the bubble tube 402 to ensure that the measuring cylinder 5 remains horizontal. When the bubble is detected to be in the center, it indicates that the measuring cylinder 5 has reached the ideal horizontal position. At this time, the photoelectric sensor 14 sends a signal to the controller 13. After receiving this signal, the controller 13 immediately instructs the motor 3035 to stop working, thereby completing the angle adjustment process of the measuring cylinder 5. This not only improves the accuracy of the positioning of the measuring cylinder 5, but also enhances the stability and reliability of the entire detection device, providing strong support for accurately assessing the water seepage performance of the roadbed.
[0035] In one embodiment, the height adjustment component 9 includes a connecting pipe 901 disposed at the bottom of the base plate 1. A movable plate 902 is disposed at the bottom of the outer circumference of the connecting pipe 901, and the movable plate 902 is connected to the base plate 1 through two sets of electric telescopic rods 903. A sealing ring 904 is disposed at the bottom of the movable plate 902, and a proximity sensor 905 is disposed on one side of the movable plate 902. A recovery pipe 906 is disposed at the middle of the outer circumference of the connecting pipe 901, and a second water pump 907 is disposed at the top of the recovery pipe 906. The second water pump 907 cooperates with the water storage tank 7. The top and bottom of the connecting pipe 901 are both pleated structures to realize the extension and retraction of the connecting pipe 901, thereby enhancing the sealing performance at the contact point between the detection device and the roadbed surface and effectively preventing water leakage in non-target areas.
[0036] The working principle of the height adjustment component 9 is as follows: The operator starts the electric telescopic rod 903 through the controller 13, which drives the moving plate 902 to move downward. During this process, the proximity sensor 905 (for example, the aforementioned proximity sensor 905 can be model E2E-X5ME1, model IM12-04BPS-ZW1, etc.) is used to detect whether the sealing ring 904 is tightly attached to the roadbed surface. When it is detected that the sealing ring 904 is completely attached to the roadbed surface, the proximity sensor 905 sends a signal to the controller 13. After receiving this signal, the controller 13 immediately instructs the electric telescopic rod 903 to stop working, thereby realizing the efficient and automated completion of the entire telescopic adjustment process. This not only improves work efficiency but also ensures the reliability of the sealing effect, providing a guarantee for subsequent accurate testing.
[0037] In one embodiment, the water guide pipe 6 has a flexible tube structure on the side near the measuring cylinder 5 to adjust the angle of the measuring cylinder 5, thereby assisting in the adjustment of the detection device and improving the accuracy of the detection results.
[0038] It should be further explained that, based on the specific needs of the seepage detection along the route, the staff sends a start command through the human-machine interface (HMI) of the controller 13. This command is transmitted to the PLC (Programmable Logic Controller) via the HMI. Upon receiving the command, the PLC drives the electric telescopic pole 903 to move to a preset distance and precisely controls the motor 3035 to rotate to a specified number of revolutions, ensuring that the equipment can accurately execute the operation according to the set requirements, achieving efficient and accurate roadbed seepage detection. After the detection is completed, the PLC controls the motor 3035 to return the adjusting plate 302 to the initial horizontal position and restore the electric telescopic pole 903 to the starting position. During this process, the proximity sensor 905 and the photoelectric sensor 14 continuously monitor and feedback the status information of the device to the PLC to confirm that the adjusting plate 302 has been adjusted to a horizontal state and that the electric telescopic pole 903 has been accurately reset to the predetermined starting point. After the reset is complete, the detection device will check each component through a self-test program to ensure that all systems are in normal working condition. The self-test program will verify whether the device is ready to start the next task based on sensor data. If the self-test confirms that there are no errors, the PLC will execute the next start operation according to the new instructions on the HMI interface, and the detection device will enter a new roadbed seepage detection task to ensure that each operation is executed efficiently and accurately.
[0039] 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.
[0040] In practical application, the operator uses push rod 12 to push the detection device to the area to be detected and uses the braking mechanism on the caster wheel 10 to secure it firmly. The height adjustment component 9 is activated via the human-machine interface (HMI) of controller 13, ensuring the sealing ring 904 tightly adheres to the roadbed surface, guaranteeing the sealing effect of the detection device (the working principle of the height adjustment component 9 is as described above). The water pump 8 is activated via controller 13, drawing water from the water tank 7 and injecting it into the measuring cylinder 5 through the water pipe 6. Under gravity, the water in the measuring cylinder 5 flows through the angle adjustment component 3 into the height adjustment component 9, contacting the roadbed. Simultaneously, based on the actual slope of the roadbed, the pump 8 is activated... The angle adjustment component 3 adjusts the tilt angle of the measuring cylinder 5, and with the assistance of the horizontal adjustment component 4, ensures that the measuring cylinder 5 is kept in a horizontal state (the working principle of the angle adjustment component 3 and the horizontal adjustment component 4 is as described above), thereby improving the stability of the roadbed seepage detection. After the water level in the measuring cylinder 5 stabilizes, the change in water volume is recorded by monitoring the height change of the float 15 in the measuring cylinder 5. As water gradually seeps into the roadbed, the height of the float 15 will decrease accordingly, thereby obtaining the detection data of the roadbed seepage performance. After the detection is completed, the second water pump 907 is started to pump the water in the connecting pipe 901 back and recover it to the water storage tank 7 to improve the recycling rate of water resources.
[0041] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated operation of the angle adjustment component 3 and the level adjustment component 4, the angle of the measuring cylinder 5 can be automatically adjusted to adapt to the actual slope of the roadbed, ensuring that the measuring cylinder 5 always remains horizontal. This effectively avoids measurement errors caused by tilting and significantly improves the accuracy and reliability of the assessment of roadbed permeability performance. By setting the height adjustment component 9, it is ensured that the sealing ring 904 precisely fits the roadbed surface, which not only enhances the sealing performance at the contact point between the detection device and the roadbed surface, effectively preventing water leakage in non-target areas, but also significantly improves the accuracy of the detection results.
