Description

Technical Field

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

[0002] Road surface water permeability testing is an important means of assessing the water stability of asphalt pavement. It is generally conducted using a road surface water permeability meter. The road surface water permeability meter calculates the permeability coefficient by measuring the time it takes for the water level to drop from the 100mL mark to the 50mL mark. During the test, the base and the road surface are sealed with sealing material to prevent water from leaking out from the base.

[0003] Patent document CN219758021U discloses a road surface seepage detection device, which includes: a top plate, a bottom plate, a measuring tube, and a main body. The bottom plate is provided at the bottom end of the top plate, and the main body is fixedly installed on the surface of the bottom plate. Compared with traditional road surface seepage detection devices, this device allows for flexible adjustment of the overall height of the main body during use. After the main body contacts the sealing material on the ground, the rotation of the screw can strengthen the contact force and intensity between the main body and the ground material, eliminating the need for additional counterweights. This makes the device more convenient and stable to use, improves the accuracy of the data during detection, and allows for rapid movement and transport of the entire device. Tools and materials used in the detection process can also be placed inside the device for transport and movement, making the device more convenient to use, reducing the workload of the staff, and improving overall work efficiency.

[0004] However, the aforementioned public document's road seepage detection device mainly addresses the problem that existing seepage detection devices are not convenient to use and cannot improve work efficiency. However, the excessive addition of structures to the outside of the seepage detector in this device can actually affect the use of the seepage detector, easily obstruct the main body, and make it inconvenient for staff to operate. The addition of transmission structures such as motors makes the structure complex and prone to damage. Moreover, it requires a power supply system, resulting in a large size of the detection device that is inconvenient to carry. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Please see Figures 1 to 5 This application proposes a road surface seepage detection device, including a sealing base 1, mounting shafts 13, connecting discs 14, elastic connecting components 30, moving components 28, and pressure applying components 29. The sealing base 1 is generally arranged in a disc shape, with a circular groove at the bottom. Four mounting shafts 13 are symmetrically installed, with their bottom ends installed on the top of the sealing base 1. The connecting discs 14 are respectively installed on the top of the mounting shafts 13. The elastic connecting components 30 are arranged on both sides of the top of the sealing base 1 via the mounting shafts 13, and two sets are symmetrically arranged. The moving components 28 are respectively arranged on one side of the elastic connecting components 30. The pressure applying components 29 are respectively arranged on the top of the moving components 28.

[0021] In the embodiments provided in this application, the sealing base 1 is used to seal the bottom of the detection device. Before sealing, the location where water seepage detection is required is encircled by the sealing slurry, and then the detection device is placed on top of the sealing slurry through the sealing base 1, so that the bottom of the sealing base 1 and the ground being tested have a better sealing effect. The mounting shaft 13 and the connecting plate 14 enable the elastic connecting assembly 30 to be symmetrically installed on top of the sealing base 1. The elastic connecting assembly 30 enables the moving assembly 28 to be elastically connected to the sealing base 1, so that the device can move up and down under the support of the moving assembly 28. The pressure applying assembly 29 is used to apply downward pressure to the detection device, so that the sealing base 1 is pressed on top of the sealing slurry.

[0022] In some embodiments of this application, the elastic connection assembly 30 includes a sleeve 15, a spring 16, a mating rod 17, and a connecting rod 18. The inner side of the sleeve 15 is fitted over the outer side of the mounting shaft 13 and is located above the sealing base 1. The bottom end of the spring 16 is mounted on the top of the sleeve 15, and the top end is fixed to the bottom of the connecting plate 14 and is located outside the mounting shaft 13. The mating rod 17 is located between the sleeves 15, and its two ends are respectively connected to the outer side of the sleeve 15. One end of the connecting rod 18 is fixed to one side of the sleeve 15.

[0023] The connecting rod 17 improves the stability of the elastic connection assembly 30 by connecting the sleeve 15. The elastic connection assembly 30 is installed on the mounting shaft 13 by the sleeve 15, and then, under the connection of the spring 16, the elastic connection assembly 30 is elastically installed on the top of the sealing base 1. The connecting rod 18 is used to connect the moving assembly 28. The spring 16 in the elastic connection assembly 30 is stretched when the sealing base 1 moves downward. After the sealing base 1 is used, it automatically moves upward back to its original height under the action of the spring 16.

[0024] In some embodiments of this application, the movable component 28 includes a movable frame 19, a movable wheel 20, and a fixing hole 21. The outer side of the movable frame 19 is connected to the other end of the connecting rod 18, and the whole is arranged in an inverted U-shaped rod body. The top of the movable wheel 20 is connected to the bottom end of the movable frame 19 and can be locked so that it cannot rotate. The fixing hole 21 is located in the middle of one side of the movable frame 19, and a threaded structure is provided inside it.

[0025] The moving component 28 is moved by the moving wheels 20. The moving component 28 supports the detection device. Since the detection device needs to detect water seepage on the road surface at different locations, the moving component 28 facilitates the movement of the detection device, making it easier to move and saving time and effort. At the same time, the moving component 28 has a simple structure, occupies a small area, and does not obstruct the main body of the water seepage detection device too much. When the sealing base 1 is connected to the sealing slurry, the staff can observe more clearly and prevent the connection from shifting. The moving wheels 20 can be locked to ensure the stability of the detection device.

[0026] In some embodiments of this application, the pressure application assembly 29 includes a fixing sleeve 22, a fixing bolt 23, a right-angle plate 24, a threaded mounting hole 25, a pressure application screw 26, and a rotating handle 27; the fixing sleeve 22 is fitted onto the top middle position of the movable frame 19; the fixing bolt 23 is threaded through one side of the fixing sleeve 22 and threadedly connected to the fixing hole 21; the right-angle plate 24 is disposed on the top of the fixing sleeve 22, with the right angle at the top facing inward; the threaded mounting hole 25 is opened on the top of the right-angle plate 24; the pressure application screw 26 is installed on the top of the right-angle plate 24 through the threaded mounting hole 25, and its bottom end penetrates the inner wall of the right-angle plate 24; the rotating handle 27 is disposed on the top end of the pressure application screw 26.

[0027] The fixing sleeve 22 is fixed to the outside of the moving frame 19 by fixing bolt 23, so that the right angle plate 24 is installed on the top of the moving frame 19. When the device is moved to the designated position by the moving component 28, the operator rotates the pressure screw 26 by turning the handle 27. Since the pressure screw 26 is installed through the threaded mounting hole 25, the bottom end of the pressure screw 26 moves downward to apply pressure to the mounting plate 3, thereby driving the sealing base 1 to move downward and press on the sealing slurry. There is no need to use an electric structure to provide power, so there is no need to equip it with a power supply or other circuit system, reducing the weight and volume of the device, making it easy to store and carry, and it will not be easily damaged.

[0028] In some embodiments of this application, the bottom of the sealing base 1 is provided with a drain hole 11 and an exhaust hole 12, and the exhaust hole 12 is located on one side of the drain hole 11. The top of the sealing base 1 is provided with an exhaust pipe 9 connected to the exhaust hole 12, and the top end of the exhaust pipe 9 is provided with a threaded plug 10.

[0029] The drain hole 11 allows the liquid used for seepage detection to be discharged onto the sealed road surface. The gas in the sealed space is transmitted through the vent hole 12 and finally discharged through the vent pipe 9. After the venting is completed, the top is sealed with the threaded plug 10 to prevent the liquid from flowing out.

[0030] Furthermore, a connecting pipe 7 is installed at the top center of the sealing base 1, and the connecting pipe 7 is connected to the top of the drain hole 11. A control valve 8 is installed on the outside of the connecting pipe 7. The connecting pipe 7 allows the liquid in the measuring cylinder 5 to be discharged through transmission to the bottom, and the control valve 8 is used to control the flow of the liquid.

[0031] Furthermore, four support rods 2 are symmetrically installed on the top of the sealing base 1. A mounting plate 3 is installed through the top of each support rod 2, and the mounting plate 3 is located below the bottom end of the pressure screw 26. The support rods 2 are used to fix the mounting plate 3 to the sealing base 1, and the mounting plate 3 provides a position for the installation of the mounting cylinder 4.

[0032] Furthermore, an installation cylinder 4 is installed on the top of the installation plate 3, and the installation cylinder 4 is connected to the connecting pipe 7. A measuring cylinder 5 is installed inside the installation cylinder 4, and a scale line 6 is installed on the outside of the measuring cylinder 5. The installation cylinder 4 is used to install the measuring cylinder 5, and the inside of the measuring cylinder 5 is used to add liquid for leakage detection. The scale line 6 makes it convenient for staff to observe the liquid level inside the measuring cylinder 5.

[0033] Working principle: First, before conducting water seepage detection, multiple detection positions need to be marked on the road surface. Then, sealant is used to surround the detection positions in a circle. The detection device is then moved above the detection position by the moving component 28. The operator rotates the handle 27 to rotate the pressure screw 26, causing the pressure screw 26 to move downward and apply pressure to the device. This causes the sealing base 1 at the bottom of the device to move downward. At this time, the spring 16 is stretched, causing the sealing base 1 to press against the top of the sealant, so that the bottom of the device is sealed with the road surface, and no liquid will flow out during water seepage detection.

[0034] Next, the staff adds liquid into the measuring cylinder 5. The liquid enters the sealed space through the connecting pipe 7 and the drain hole 11. After the gas inside the space is discharged through the vent hole 12 and the vent pipe 9, the connecting pipe 7 is closed by the control valve 8, and the top of the vent pipe 9 is sealed by the threaded plug 10. Then, liquid is added into the measuring cylinder 5 again. At this time, the control valve 8 is opened, and the liquid flows downward. The liquid will seep into the road surface inside the sealed space. The staff times the falling speed of the liquid in the measuring cylinder 5 to detect the water seepage on the road surface.
