Description
Technical Field
[0001] This invention relates to the field of asphalt pavement testing, and more specifically, to a device for detecting water seepage during asphalt pavement construction. Background Technology
[0002] Water seepage testing during asphalt pavement construction is an important aspect of engineering quality inspection. It primarily assesses whether the asphalt pavement possesses good waterproofing properties after construction, preventing water from seeping into the pavement structure and thus ensuring the pavement's durability and service life. The following is a detailed explanation of water seepage testing: Definition and Importance of Water Seepage Testing: Water seepage testing uses specific methods and instruments to test the water permeability of the asphalt pavement surface. Its purpose is to ensure that the pavement meets the designed drainage standards after construction.
[0003] Existing testing devices require multiple points of inspection on a single road surface to improve data accuracy. The process involves first applying sealant, then placing the testing device on top of it. This manual application of sealant each time increases workload and inefficiency. Furthermore, the soft sealant causes the device to shift when pressed down, resulting in poor adhesion and potential leaks. This further complicates the testing process and causes numerous inconveniences.
[0004] Therefore, a device for detecting water seepage during asphalt pavement construction is proposed. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) When the pressure block moves down, it can automatically spray glue. The rotating block sprays glue around the circle to form an annular sealing ring. The pressure block moves down and fits with the sealant. The rotating block also has a certain annular limiting effect on the sealant, which makes the fit between the pressure block and the sealant better, avoids water leakage, and allows water to seep out through the asphalt pavement, thus making the testing work more efficient and improving the sealing effect and the accuracy of the test data.
[0018] (2) The ring block is located at the top of the rotating block. The bottom end can limit the sealant to prevent it from overflowing. At the same time, the movement of the ring block can make the top of the sealant liquid flat, thereby improving the adhesion between the sealant and the pressure block, further improving the sealing degree, and making the test effect better.
[0019] (3) When the test is finished, the screw rod reverses, which causes the rotating block to rotate. Under the action of the L-shaped rod, the rotating block scrapes off the sealant that is highly adhered to the inner wall of the rotating block, so as to avoid the sealant adhering to the side wall of the rotating block and affecting the next glue spraying work, thus improving the use effect.
[0020] (4) When the ring block rotates, the protrusions collide and rub against each other, which causes the ring block to vibrate. When the ring block vibrates, it can make the rotating block rotate. The vibration of the rotating block can better help the sealant to release air, thereby improving the sealing effect. At the same time, when the L-shaped rod cleans the inner wall of the rotating block, the vibration can help the sealant to separate from the inner wall of the rotating block, improving the ease of use.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1 to 9A device for detecting water seepage in asphalt pavement construction includes a vehicle body 1, with the lower end of the vehicle body 1 close to the ground. Inside the vehicle body 1 is a measuring cylinder 12 for holding water. A horizontal plate 10 is fixedly connected to the lower end of the measuring cylinder 12, and a support rod 13 is fixedly connected to the lower end of the horizontal plate 10. A pressure block 15 is fixedly connected to the lower end of the support rod 13 and is used to press on the asphalt pavement. A pipe fitting 19 connected to the lower end of the pressure block 15 is fixedly connected to the upper end of the pressure block 15, which communicates with the lower end of the measuring cylinder 12. Water inside the measuring cylinder 12 is guided to the pressure block 15 through the pipe fitting 19 to detect water seepage in the asphalt pavement. A valve 14 is fixedly connected to the right side of the pipe fitting 19 to control the flow of water through the pipe fitting 19. Inside the vehicle body 1 is a spraying assembly for filling the lower end of the pressure block 15 with sealant. The spraying assembly includes a U-shaped support plate 3 fixedly connected to the upper end of the vehicle body 1. The U-shaped support plate 3 provides support, and a threaded rod 4 is threadedly connected inside the U-shaped support plate 3. By rotating the threaded rod 4, it can move up and down. A connecting plate 7 is provided at the lower end of the threaded rod 4, and the lower end of the connecting plate 7 is fixedly connected to the upper end of the horizontal plate 10. Movable grooves 8 are provided on both sides of the U-shaped support plate 3, and extension plates 9 are provided on both sides of the connecting plate 7. The extension plates 9 can move up and down inside the movable grooves 8. The lower end of the vehicle body 1 is rotatably connected to... Rotating block 28 is rotatable relative to the lower end of vehicle body 1. A nozzle 32 is installed inside rotating block 28 for spraying material. A toothed block 27 is fixedly connected to the outer side of rotating block 28. A spiral rod 5 is threadedly connected to the inside of the left extension plate 9. When the extension plate 9 moves up and down, the spiral rod 5 rotates. The rod wall of the spiral rod 5 is rotatably connected to the inside of vehicle body 1, allowing the spiral rod 5 to rotate relative to vehicle body 1. A gear 26 is fixedly connected to the lower end of the spiral rod 5. The rotation of the spiral rod 5 drives the gear 26 to rotate. The outer side of gear 6 meshes with the toothed block 27. When gear 26 rotates, it causes the toothed block 27 to move. An annular plate 31 is rotatably connected to the outer side of the rotating block 28. The annular plate 31 and the rotating block 28 can rotate relative to each other. The annular plate 31 is fixedly connected to the lower end of the vehicle body 1. A liquid cylinder 21 is fixedly connected to the upper right side of the vehicle body 1. The liquid cylinder 21 contains sealant. A first conduit 25 is fixedly connected to the lower end of the liquid cylinder 21. The first conduit 25 is used to guide the sealant inside the liquid cylinder 21 into the interior of the cylinder 33. The lower inner wall of the vehicle body 1 is fixedly connected to... A cylinder 33 is connected to a circular block 34 that is slidably connected to the upper end of the cylinder 33. The circular block 34 can move up and down relative to the cylinder 33. A connecting rod 20 is provided at the upper end of the circular block 34. The upper end of the connecting rod 20 is fixedly connected to the right extension plate 9. The right extension plate 9 moves up and down, which drives the connecting rod 20 to move up and down, and in turn drives the circular block 34 to move up and down. A second conduit 36 is provided at the lower end of the cylinder 33. The second conduit 36 is fixedly connected to the right side of the annular plate 31. The second conduit 36 squeezes the sealant inside the cylinder 33 into the interior of the rotating block 28. The vehicle body 1 is moved to the required working position. Locks are installed on the moving wheels of the vehicle body 1 to limit their movement, fixing the device relative to the ground. Then, by rotating the threaded rod 4, it moves downwards. This downward movement of the threaded rod 4 causes the connecting plate 7 to move downwards, which in turn causes the horizontal plate 10 to move downwards. This movement is transmitted via the support rod 13, which in turn causes the pressure block 15 to move downwards. Simultaneously, as the connecting plate 7 moves downwards, it causes the extension plates 9 on both sides to move downwards within the moving groove 8. The left extension plate 9 moves downwards... When the device moves, the screw rod 5 rotates, which in turn drives the gear 26 to rotate. The gear 26 then moves the toothed block 27, which in turn causes the rotating block 28 to rotate. The extension plate 9 on the right moves downwards, causing the connecting rod 20 to move downwards. This downward movement of the connecting rod 20 causes the circular block 34 to move downwards. The downward movement of the circular block 34 squeezes out the sealant inside the cylinder 33, which is then introduced into the rotating block 28 through the second conduit 36 and sprayed out from the nozzle 32. Because the rotating block 28 rotates continuously, the nozzle 32 sprays the sealant in a ring shape, requiring... It is explained that when the connecting rod 20 moves downward, it causes the circular block 34 to move downward, squeezing out the adhesive inside the cylinder 33. As the circular block 34 moves downward, it seals the left side of the first conduit 25. When the circular block 34 moves upward, and its lower end is positioned above the lower end of the first conduit 25, the adhesive inside the liquid cylinder 21 flows into the cylinder 33 through the first conduit 25. As the pressure block 15 moves downward, it contacts the sealant, and then liquid is injected into the measuring cylinder 12. The valve 14 is opened, and the speed is measured using a stopwatch. This process... During testing, the device automatically sprays adhesive as the pressure block 15 moves downwards. The rotating block 28 sprays adhesive around the circle, forming a ring-shaped seal. As the pressure block 15 moves downwards, it adheres to the sealant. The rotating block 28 also provides a certain ring-shaped limiting effect on the sealant, resulting in a better fit between the pressure block 15 and the sealant. This allows the pressure block 15 to move downwards stably without any positional deviation, preventing water leakage. Water can only seep out through the asphalt pavement, making the testing work more efficient, improving the sealing effect, and enhancing the accuracy of the test data.
[0025] like Figure 5 As shown, the wall of the connecting rod 20 is slidably connected to the interior of the vehicle body 1, and the lower end of the connecting rod 20 is slidably connected to the upper end of the circular block 34. A first spring 35 is fixedly connected between the connecting rod 20 and the circular block 34. When the circular block 34 moves to the bottom of the cylinder 33, the connecting plate 7 continues to drive the pressure block 15 to move downward. At this time, the connecting rod 20 compresses the first spring 35, so that when the pressure block 15 comes into contact with the sealant, the nozzle 32 no longer dispenses sealant, thus avoiding affecting the adhesion between the pressure block 15 and the sealant. like Figure 2 , Figure 2 , Figure 5 and Figure 6 As shown, rectangular blocks 30 are slidably connected to both sides of the rotating block 28. A second spring 29 is fixedly connected to one side of the rectangular block 30 and the rotating block 28. An annular block 37 is fixedly connected to one side of the rectangular block 30. The upper end of the annular block 37 is inclined. The rectangular block 30 can move inside the rotating block 28. The second spring 29 provides some support for the rectangular block 30. When the rotating block 28 rotates, it drives the rectangular block 30 to move. The rectangular block 30 drives the annular block 37 to move. When the pressure block 15 moves downward, the annular block 37 moves outward from the rotating block 28 under the action of the inclined surface. It will not interfere with the movement of the pressure block 28. The annular block 37 is located at the upper end of the rotating block 28. The lower end can limit the sealant to prevent it from overflowing. At the same time, the movement of the annular block 37 can make the upper end of the sealant liquid flat, thereby improving the adhesion between the sealant and the pressure block 15, further improving the sealing degree, and making the detection effect better.
[0026] like Figure 2 and Figure 9 As shown, support blocks 44 are fixedly connected to both sides of the lower end of the vehicle body 1. A movable block 45 is slidably connected inside the support block 44. The movable block 45 can move left and right inside the support block 44. An L-shaped rod 11 is provided at the lower end of the movable block 45. A third spring 6 is fixedly connected to one side of the movable block 45. The third spring 6 can pull the movable block 45 to move. One side of the L-shaped rod 11 is in contact with the inner wall of the rotating block 28. The rotating block 28 can rotate relative to the L-shaped rod 11. The third spring 6 exerts a certain pulling force on the moving block 45, which makes the L-shaped rod 11 fit against the inner wall of the rotating block 28. When the test is finished, the spiral rod 5 reverses, which makes the rotating block 28 rotate. Under the action of the L-shaped rod 11, the rotating block 28 scrapes off the sealant that is highly adhered to the inner wall of the rotating block 28, preventing the sealant from adhering to the side wall of the rotating block 28 and affecting the next glue spraying work, thus improving the use effect.
[0027] like Figure 9 As shown, a slide rod 46 is fixedly connected inside the support block 44. The wall of the slide rod 46 is slidably connected to the moving block 45. The slide rod 46 enables the moving block 45 to move stably. like Figure 6 As shown, a movable rod 38 is slidably connected to the lower inner wall of the vehicle body 1. A fourth spring 39 is sleeved on the rod wall of the movable rod 38. An arc plate 40 is fixedly connected to one side of the movable rod 38. A protrusion 41 is fixedly connected to one side of the arc plate 40 and one side of the annular block 37. The movable rod 38 can move at the upper end of the vehicle body 1. The fourth spring 39 provides a certain support force to the movable rod 38, which causes the arc plate 40 to fit with the annular block 37. When the annular block 37 rotates, the protrusions 41 collide and rub against each other, which causes the annular block 37 to vibrate. When the annular block 37 vibrates, it can cause the rotating block 28 to rotate. The vibration of the rotating block 28 can better help the sealant to vent, thereby improving the sealing effect. At the same time, when the L-shaped rod 11 cleans the inner wall of the rotating block 28, the vibration can help the sealant to detach from the inner wall of the rotating block 28, improving the ease of use.
[0028] like Figure 4 As shown, a vertical rod 42 is slidably connected to the lower end of the threaded rod 4. The vertical rod 42 can move up and down relative to the threaded rod 4. The lower end of the vertical rod 42 is rotatably connected to the upper end of the connecting plate 7. A fifth spring 43 is fixedly connected to the upper end of the vertical rod 42. The upper end of the fifth spring 43 is connected to the inside of the threaded rod 4. When the threaded rod 4 moves downward, it drives the vertical rod 42 to move downward through the fifth spring 43. The downward movement of the vertical rod 42 drives the connecting plate 7 to move downward. When the pressure block 15 comes into contact with the sealant, the threaded rod 4 continues to rotate, causing the fifth spring 43 to be compressed. Under the action of the fifth spring 43, the pressure block 15 always has a downward force, which makes the pressure block 15 adhere stably to the sealant.
[0029] like Figure 2 and Figure 8 As shown, a stop block 16 is fixedly connected inside the pressure block 15, and a float block 17 is slidably connected to the left side of the pressure block 15. The lower end of the float block 17 is located at the upper end of the stop block 16, and rectangular grooves 18 are evenly opened on the outer side of the float block 17. The existing device requires human observation during venting, and the vent pipe must be blocked when water flows out, which is inconvenient to use; When water is injected into the pressure block 15, the gas inside is continuously discharged through the rectangular groove 18. When the water block is full, the float 17 moves upward under the buoyancy of the water. When the float 17 moves upward, it is embedded in the interior of the pressure block 15, thereby achieving a seal and preventing liquid from flowing out. This method is more convenient when venting.
[0030] like Figure 1 and Figure 2 As shown, a pressure valve is provided on the left side of the second conduit 36, which allows the adhesive to be discharged only when there is pressure. The height of the circular block 34 is the same as the height of the cylinder 33. A gravity block 2 is fixedly connected to the upper left side of the vehicle body 1. The gravity block 2 makes the entire device heavier, thus ensuring that the pressure block 15 is in a stable state. like Figure 2As shown, a movable plate 22 is slidably connected inside the liquid cylinder 21. A round rod 23 is fixedly connected to the upper end of the movable plate 22. A sixth spring 24 is sleeved on the rod wall of the round rod 23. The sixth spring 24 exerts downward pressure on the round rod 23, which in turn causes the movable plate 22 to have a downward moving force, thereby facilitating the discharge of sealant. A liquid inlet valve is provided at the lower right end of the liquid cylinder 21 for replenishing sealant inside the liquid cylinder 21.
[0031] Working principle: The vehicle body 1 is moved to the required working position. Locks on the moving wheels of the vehicle body 1 limit the movement of the wheels, fixing the device relative to the ground. Then, by rotating the threaded rod 4, it moves downwards. This downward movement of the threaded rod 4 causes the connecting plate 7 to move downwards, which in turn causes the horizontal plate 10 to move downwards. This movement is transmitted through the support rod 13, which in turn causes the pressure block 15 to move downwards. Simultaneously, as the connecting plate 7 moves downwards, it causes the extension plates 9 on both sides to move downwards within the moving groove 8. (Left...) When the extension plate 9 on the side moves downward, it causes the spiral rod 5 to rotate. The rotation of the spiral rod 5 drives the gear 26 to rotate, which in turn causes the toothed block 27 to move. The toothed block 27 then causes the rotating block 28 to rotate. The downward movement of the extension plate 9 on the right side causes the connecting rod 20 to move downward. As the connecting rod 20 moves downward, it causes the circular block 34 to move downward. The downward movement of the circular block 34 squeezes out the sealant inside the cylinder 33, which is then introduced into the rotating block 28 through the second conduit 36 and sprayed out from the nozzle 32. Because the rotating block 28 rotates continuously, the nozzle 32... When spraying the adhesive, it forms a ring shape. It should be noted that when the connecting rod 20 moves downwards, it causes the circular block 34 to move downwards, squeezing out the adhesive from inside the cylinder 33. As the circular block 34 moves downwards, it seals the left side of the first conduit 25. When the circular block 34 moves upwards, and its lower end is above the lower end of the first conduit 25, the adhesive from inside the liquid cylinder 21 flows into the cylinder 33 through the first conduit 25. As the pressure block 15 moves downwards, it contacts the sealant, and then liquid is injected into the measuring cylinder 12, opening... Valve 14 is used, and then a stopwatch is used to measure the speed. During the test, when the pressure block 15 moves down, the adhesive is automatically sprayed. The rotating block 28 sprays adhesive around the circle, thus forming an annular sealing ring. The pressure block 15 moves down and adheres to the sealant. The rotating block 28 also has a certain annular limiting effect on the sealant, which makes the adhesion between the pressure block 15 and the sealant better, preventing water leakage. Water can only seep out through the asphalt pavement, thus making the test work more efficient, improving the sealing effect, and improving the accuracy of the test data. Furthermore, when the rotating block 28 rotates, it drives the rectangular block 30 to move, and the rectangular block 30 drives the annular block 37 to move. When the pressure block 15 moves downward, the annular block 37 moves outward from the rotating block 28 under the action of the inclined surface, without interfering with the movement of the pressure block 28. The annular block 37 is located at the upper end of the rotating block 28, and its lower end can limit the sealant to prevent it from overflowing. At the same time, the movement of the annular block 37 can make the upper end of the sealant liquid flat, thereby improving the adhesion between the sealant and the pressure block 15, further improving the sealing degree, and making the detection effect better. Furthermore, the rotating block 28 can rotate relative to the L-shaped rod 11, and the third spring 6 exerts a certain pulling force on the moving block 45, thereby causing the L-shaped rod 11 to fit against the inner wall of the rotating block 28. When the test is finished, the spiral rod 5 reverses, thereby causing the rotating block 28 to rotate. Under the action of the L-shaped rod 11, the rotating block 28 scrapes off the sealant that is highly adhered to the inner wall of the rotating block 28, preventing the sealant from adhering to the side wall of the rotating block 28 and affecting the next glue spraying work, thus improving the use effect. Furthermore, the movable rod 38 can move at the upper end of the vehicle body 1. The fourth spring 39 provides a certain support force to the movable rod 38, thereby causing the arc plate 40 to fit with the annular block 37. When the annular block 37 rotates, the protrusions 41 collide and rub against each other, thereby causing the annular block 37 to vibrate. When the annular block 37 vibrates, it can cause the rotating block 28 to rotate. The vibration of the rotating block 28 can better help the sealant to release air, thereby improving the sealing effect. At the same time, when the L-shaped rod 11 cleans the inner wall of the rotating block 28, the vibration can help the sealant to detach from the inner wall of the rotating block 28, improving the ease of use. Furthermore, when the threaded rod 4 moves downward, it drives the vertical rod 42 to move downward through the fifth spring 43. The vertical rod 42 moves downward, which in turn drives the connecting plate 7 to move downward. When the pressure block 15 comes into contact with the sealant, the threaded rod 4 continues to rotate, which compresses the fifth spring 43. In this way, under the action of the fifth spring 43, the pressure block 15 always has a downward force, which makes the pressure block 15 adhere stably to the sealant. Furthermore, when water is injected into the pressure block 15, the gas inside is continuously discharged through the rectangular groove 18. When the water block is full, the float 17 moves upward under the buoyancy of the water. When the float 17 moves upward, it is embedded inside the pressure block 15, thereby achieving a seal and preventing liquid from flowing out. This method is more convenient when venting.
