Description

Technical Field

[0001] This utility model relates to the field of road surface testing technology, and in particular to a road surface water seepage detection device. Background Technology

[0002] In the vast field of highway construction and maintenance, pavement permeability, as a key indicator for measuring pavement quality and assessing its durability, has always received widespread attention within the industry. Permeability not only directly relates to the drainage efficiency of the pavement but also profoundly affects road safety and the long-term stability of the pavement structure. Therefore, accurate and efficient detection of pavement permeability is of paramount importance for the timely discovery and repair of pavement defects, ensuring unimpeded highway traffic.

[0003] Traditional methods for detecting pavement seepage, such as the manual water-pouring method and the seepage volume measuring instrument method, can meet the testing needs to a certain extent, but their limitations are becoming increasingly apparent. The manual water-pouring method relies on the operator's experience and judgment, making it difficult to ensure the consistency of testing conditions, resulting in significant subjectivity and uncertainty in the test results. While the seepage volume measuring instrument method improves the objectivity and accuracy of the test, it often requires the installation of a sealing layer, which usually requires manual operation by the testing personnel. The sealing performance is often ensured manually and relies on human experience.

[0004] Solving the aforementioned technical problems is the challenge facing this utility model. Summary of the Invention

Simultaneously, through two symmetrically arranged sets of hydraulic extrusion rods and several electric extrusion rods, pressure can be applied evenly and precisely, allowing the gel-like substance to completely fill the gaps and make close contact with the road surface, further enhancing the sealing effect.

This vibration damping design makes the device suitable for various complex and uneven road surface conditions, thus greatly improving its application range and adaptability.

[0023] This invention combines a stable placement component with a seepage detector, enabling efficient and interference-free seepage detection. During operation, precise positioning and quantitative control allow for rapid completion of seepage detection tasks, significantly saving detection time and improving work efficiency. Furthermore, the design of the measuring cylinder and seepage chamber allows for real-time monitoring of seepage, ensuring timely feedback of detection data and facilitating rapid maintenance decisions.

[0034] Specifically, this type of gelatinous substance can be made from flour dough or from mud mixed with water.

[0035] Specifically, the stable base 100 serves as the supporting foundation for the entire testing device, ensuring its stability during the testing process. The first bracket 110 and the second bracket 120 work together to provide a stable support frame for the extrusion cylinder 400 and the water seepage detector 800. The vertical shock absorption component 300 reduces interference from external factors during the testing process, ensuring the accuracy of the test data. The stable support component 500, mounted on the second bracket 120, provides additional support and shock absorption. The telescopic arm 520 and the connecting arc plate 530 are used to tightly connect the extrusion cylinder 400 to the stable support component 500, ensuring its stability during the testing process. The extrusion cylinder 400, as a key component in the formation of the sealing layer, contains a gel-like substance. Its structural design ensures that the gel-like substance is evenly distributed and tightly adheres to the road surface to be tested during extrusion. The extrusion assembly 600 applies pressure to the gel-like material, deforming it and causing it to adhere tightly to the road surface, forming a sealed environment. Simultaneously, it can also compress the permeability detector 800, further meeting its sealing requirements. The stabilization assembly 700 is used to stably position the permeability detector 800, ensuring it does not shift during testing and affect data acquisition. The permeability detector 800 is the core tool for actual water collection and measurement. A measuring cylinder 850 records the amount of water that permeates under the road surface within a certain time period, thereby evaluating the road surface's permeability performance.

[0036] Furthermore, the vertical damping assembly 300 includes a vertical cavity 310 formed in the first bracket 110.

[0039] Specifically, the vertical damping component 300 plays a crucial technical role in the road surface seepage detection device, primarily responsible for reducing or eliminating vertical vibrations and impacts from the road surface and the device itself. These vibrations and impacts can originate from various factors, such as uneven road surfaces, vehicle traffic, wind forces, and the movement of the device itself.

[0040] Furthermore, the stable support component 500 includes a stable sleeve 510 sleeved on the second bracket 120, and a stable damping unit that cooperates with the stable sleeve 510 is provided on the second bracket 120.

[0041] The stabilizing sleeve 510 is provided with a telescopic arm 520, and the telescopic end of the telescopic arm 520 is provided with a connecting arc plate 530 that connects to the extrusion cylinder 400. The connecting arc plate 530 is provided with a connecting screw 540 that cooperates with the extrusion cylinder 400.

[0042] Specifically, the main function of the stabilizing support component 500 is to provide strong support and stability, ensuring that the seepage detection device can be firmly fixed to the road surface during the detection process, unaffected by external factors. It typically consists of multiple structural components, including a stabilizing sleeve 510, a stabilizing damping unit, a telescopic arm 520, and a connecting arc plate 530, etc.

[0043] The vertical damping component 300 and the stabilizing support component 500 work together in the highway pavement seepage detection device to improve detection accuracy, protect the device structure, enhance stability, and increase detection efficiency. They ensure that the seepage detector 800 can accurately and reliably detect pavement seepage by reducing vibration and impact forces and providing strong support and stability.

[0044] Furthermore, the extrusion assembly 600 includes two sets of extrusion hydraulic rods 610 symmetrically arranged on the extrusion frame 130. The moving ends of the two sets of extrusion hydraulic rods 610 are connected to the same extrusion base 620.

When the water seepage detector 800 is placed, the extrusion ring plate 630 is in contact with the water seepage detector 800.

[0046] Furthermore, the stable placement assembly 700 includes a placement circular frame 710 that contacts the extrusion cylinder 400. The placement circular frame 710 is provided with a placement ring plate 720 that cooperates with the extrusion cylinder 400. A plurality of placement guides 730 that are aligned with the axial direction of the placement circular frame 710 and cooperate with the seepage detector 800 are evenly arranged along the circumferential direction of the placement circular frame 710.

[0051] Preferably, the stable base 100 is provided with movable wheels.

[0052] Specifically, the extrusion assembly 600 is the core of the entire seepage detection device. Its main function is to apply pressure to the gel-like substance to form a sealing ring between the extrusion cylinder 400 and the road surface, thereby creating a closed environment for seepage detection. In addition, when placing the seepage detector 800, the extrusion assembly 600 is used to further compress and bond the seepage detector 800 with the gel-like substance, thereby further meeting the sealing requirements of the seepage detector 800.

[0053] In use, the extrusion base 620 is first placed directly above the extrusion cylinder 400 using the extrusion hydraulic rod 610. Then, the positioning screws are loosened, causing the extrusion rod 660 located in the extrusion base 620 to detach from the extrusion base 620, so that the extrusion round seat 670 located at the bottom end of the extrusion rod 660 is located in the extrusion cylinder 400. Then, the gelatinous substance, such as dough or mud, is placed in the extrusion cylinder 400. The extrusion base 620 is then placed on the extrusion cylinder 400 using the extrusion hydraulic rod 610. The extrusion rod 660 is then fixed using the positioning screws. Finally, the extrusion electric rod 640 is used to drive the extrusion ring plate 630, thereby completing the formation of the sealing layer.

[0054] After the sealing layer is formed, the hydraulic compression rod 610 is used to separate the compression base 620 from the compression cylinder 400. Then, the stable placement component 700 is placed in the compression cylinder 400. With the cooperation of the stable placement component 700, the water seepage detector 800 is stably placed on the sealing layer. Then, the electric compression rod 640 is used to drive the compression ring plate 630 to compress the water seepage detector 800, thereby further satisfying the sealing requirements of the water seepage detector 800.
