Description

Technical Field

[0001] The invention belongs to the technical field of asphalt pavement water seepage instruments, in particular to an asphalt pavement water seepage performance detection device. Background Art

[0002] Asphalt pavement water permeability meter is a special device used to measure the water permeability of asphalt pavement. It is mainly used to evaluate the drainage capacity of the road to ensure that the asphalt pavement can effectively drain water under rainy or humid conditions, thereby improving driving safety and the service life of the road. The asphalt pavement water permeability meter is mainly composed of a water seepage ring, a measuring device, a counterweight and water. By placing the water seepage ring on the asphalt pavement and ensuring its sealing, a certain amount of water is injected into the water seepage ring, and the timing is started to record the drop in the water level to calculate the water penetration rate.

[0003] Before the existing asphalt pavement water seepage meter is used for testing, it is necessary to first place the water seepage ring on the asphalt pavement to be tested, and then apply a layer of sealant around the water seepage ring to ensure the sealing during the test. When using the glue, a glue spray gun is also required for auxiliary operation, which requires a lot of equipment to carry, which brings great inconvenience to outdoor testing; at the same time, the sprayed glue is also difficult to seal the water seepage ring well, and it needs to be adjusted repeatedly, which greatly reduces the efficiency of the test.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention describes an asphalt pavement water seepage performance detection device, which uses a sliding push plate to make the push plate bring the pressure plate to squeeze the glue pre-stored in the glue storage ring into the fixed ring, and flow to the water seepage circle through the arc-shaped sliding ring. By installing a number of fixed rings and sliding rings, the outflowing glue can surround the water seepage circle, thereby improving the glue spraying efficiency while also being able to efficiently spray around the water seepage circle. When moving, the sliding ring will move with the glue spreading plate, and then use the fixed rod to push the glue spreading plate in the sliding ring, so that the glue spreading plate slides along the direction of the opening of the hollow groove. The sliding glue spreading plate will contact the glue and move and spread the sprayed glue evenly to avoid the glue being sprayed only to the corresponding place of the sliding ring, resulting in no glue in the gap between the two sliding rings, resulting in poor sealing effect of the water seepage circle. Through the designed glue dispensing mechanism and glue spreading assembly, there is no need to carry extra glue and glue spray guns when testing asphalt pavement outdoors, which greatly reduces the need to carry equipment and brings great convenience to the test; at the same time, the surrounding glue spraying and auxiliary glue spreading can better seal the water seepage circle to avoid uneven glue spreading and cause leakage.

[0017] 2. The device for detecting water seepage performance of asphalt pavement described in the present invention continuously squeezes the positioning rod in the rectangular frame when the sliding rod slides, so that the positioning rod slides and contracts into the rectangular frame. When the sliding rod moves to a suitable position, the positioning holes of the positioning rod on the sliding rod are in the same straight line. The positioning rod enters the positioning hole and is fixed under the action of the spring, thereby fixing the sliding rod. At this time, the user's hands are freed, making it convenient for the user to press the pressure plate to perform the glue discharge operation. When the glue discharge operation is completed and the bottom of the water seepage circle needs to abut against the asphalt pavement, the rectangular frame is slidably installed to disengage the positioning rod from the positioning hole, and drive the water seepage meter and the water seepage circle to abut against the asphalt pavement.

[0018] 3. The device for detecting water seepage performance of asphalt pavement described in the present invention allows gas to enter the suction cup through the hollow slide rod, so that the suction cup loses suction and is easy to pull out. First, connect the connecting tube and the ring, and then slide the slide rod to move the storage box into the rectangular frame with the slide rod. The rectangular frame is used to continuously squeeze the storage box to force the degumming agent in the storage box to enter the ring through the connecting tube and flow to the bonding point between the water seepage ring and the glue through the connecting hole at the bottom of the ring, thereby reducing the viscosity of the glue and assisting in removing the water seepage ring from the asphalt pavement. The plug designed as above can quickly remove the suction cup used for positioning, and at the same time spray out the degumming agent, thereby assisting in the disassembly of the water seepage ring, avoiding the difficulty in disassembling the water seepage ring after glue bonding, which makes it difficult to continue to use the water seepage meter.

[0019] 4. The asphalt pavement water seepage performance detection device described in the present invention increases the weight of the water seepage instrument by installing a counterweight ring on the water seepage instrument and injecting a cleaning agent, thereby eliminating the need for additional counterweight equipment. By designing the counterweight ring, the water seepage instrument can be kept vertical and stable during the test to ensure the accuracy of the measurement. At the same time, the counterweight ring can increase the center of gravity of the device to prevent tilting. The design integrates the counterweight with the water seepage instrument, which does not need to be carried extra, greatly improving portability. When the push plate moves again, it will move with the sealing assembly and the sealing plate. The sealing plate pushes the cleaning agent in the counterweight ring into the liquid guide tube and injects it into the sleeve ring, and then sprays it to the glue on the asphalt pavement through the liquid outlet hole of the sleeve ring to flush the glue, thereby flushing the glue on the ground. Then slide the slide bar in the rectangular frame so that the connecting plate on the slide bar squeezes the elastic block and aligns the air outlet pipe with the bonding point between the glue and the asphalt pavement, thereby blowing away the residual glue, achieving further cleaning of the asphalt pavement, and thus ensuring traceless operation.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 to 10 As shown, an asphalt pavement water permeability detection device according to an embodiment of the present invention comprises a water seepage meter 1, a water seepage ring 2 is fixedly installed at the bottom of the water seepage meter 1; a glue discharging mechanism 10 for storing glue is arranged on the water seepage meter 1; the glue discharging mechanism 10 comprises a glue storage ring 11 fixedly installed on the water seepage meter 1, a pressure plate 12 is slidably connected inside the glue storage ring 11, a push plate 13 passing through the glue storage ring 11 is fixedly installed on the top of the pressure plate 12, a plurality of fixed rings 15 are fixedly installed on one side of the water seepage meter 1 close to the water seepage ring 2, the fixed ring 15 is connected to the glue storage ring 11, a sliding ring 14 is slidably connected to the outer surface of the fixed ring 15, the fixed ring 15 and the sliding ring 14 are both arc-shaped, and the port of the sliding ring 14 is close to the bottom of the water seepage ring 2;

[0041] Specifically, a glue spreading component 16 for assisting in applying glue is provided on one side of the water seepage meter 1 close to the fixed ring 15. The glue spreading component 16 includes a plurality of arc-shaped fixed rods 163 fixedly mounted on the bottom of the water seepage meter 1, a hollow groove 161 is provided inside the sliding ring 14, a glue spreading plate 162 is slidably connected in the hollow groove 161 through an elastic rope, the bottom of the glue spreading plate 162 is arc-shaped, the glue spreading plate 162 is rotatably connected by a plurality of rectangular plates through a rotating shaft, and the top of the glue spreading plate 162 is in contact with the fixed rod 163.

[0042] During operation, the water seepage meter 1 is placed on the asphalt pavement to be tested, and the water seepage circle 2 at the bottom of the water seepage meter 1 is close to the asphalt pavement. The push plate 13 is slid to move the push plate 13 and the pressure plate 12 from top to bottom in the glue storage ring 11, so that the glue pre-stored in the glue storage ring 11 is squeezed into the fixed ring 15 and flows to the water seepage circle 2 through the arc-shaped sliding ring 14. By installing a plurality of fixed rings 15 and sliding rings 14, the outflowing glue can surround the water seepage circle 2, thereby improving the glue spraying efficiency and spraying it around the water seepage circle 2 efficiently.

[0043] After spraying the glue, move the water seepage meter 1 and the water seepage ring 2 again so that the water seepage ring 2 fits the asphalt pavement and is completely bonded with the glue. Since one end of the sliding ring 14 is closer to the asphalt pavement than the water seepage ring 2, when the water seepage ring 2 moves toward the asphalt pavement, the sliding ring 14 will slide and shrink toward the fixed ring 15. At the same time, since the fixed rod 163 and the top of the glue plate 162 fit together, the sliding ring 14 will move with the glue plate 162 when moving, and then the fixed rod 163 will be used to push the glue plate 162 in the sliding ring 14, so that the glue plate 162 slides along the direction of the opening of the hollow groove 161 (it should be noted that the glue plate 162 is designed to be a number of rectangular plates connected by a rotating shaft in order to facilitate sliding out of the hollow groove 161). The sliding glue plate 162 will come into contact with the glue and move and spread the sprayed glue evenly to avoid the glue being sprayed only to the corresponding place of the sliding ring 14, resulting in no glue in the gap between the two sliding rings 14, resulting in poor sealing effect of the water seepage ring 2.

[0044] Through the designed glue dispensing mechanism 10 and glue applying assembly 16, when testing the asphalt pavement outdoors, there is no need to carry additional glue and glue spray gun, which greatly reduces the need to carry equipment and brings great convenience to the test; at the same time, the surrounding glue spraying and auxiliary glue applying can better seal the seepage ring 2 to avoid uneven glue application and cause leakage.

[0045] The surface of the water seepage meter 1 is symmetrically provided with two positioning mechanisms 20. The positioning mechanisms 20 and the water seepage meter 1 are fixedly connected to a rectangular frame 21. A slide bar 22 is slidably connected inside the rectangular frame 21. A suction cup 23 is fixedly installed at the bottom of the slide bar 22. The inside of the slide bar 22 is hollow and communicates with the suction cup 23. A plug 24 is threadedly connected to the top of the slide bar 22. A number of hemispherical positioning holes 25 are provided on both sides of the slide bar 22. A positioning rod 26 is slidably connected inside the rectangular frame 21 through a spring. The end of the positioning rod 26 away from the spring is hemispherical. Two symmetrically arranged elastic blocks 27 are fixedly installed inside the rectangular frame 21. The inside of the elastic block 27 is hollow. An air outlet pipe 28 connected to the inside is fixedly installed at the bottom of the elastic block 27. The end of the air outlet pipe 28 away from the elastic block 27 is aligned with the bottom of the suction cup 23.

[0046] During operation, when placing the water seepage meter 1, the water seepage meter 1 is carried through the rectangular frame 21, and the slide bar 22 in the rectangular frame 21 is slid, so that the slide bar 22 moves with the suction cup 23 to the asphalt road surface. At this time, the protrusions on both sides of the slide bar 22 will squeeze the elastic block 27 in the rectangular frame 21, so that the gas in the elastic block 27 is sprayed to the asphalt road surface through the air outlet pipe 28, and the asphalt road surface under the suction cup 23 is blown for pre-cleaning, reducing the residual impurities, and facilitating the suction of the suction cup 23 and the asphalt road surface. When sliding, the slide bar 22 will continuously squeeze the positioning rod 26 in the rectangular frame 21, so that the positioning rod 26 slides and shrinks into the rectangular frame 21. When the slide bar 22 moves to the appropriate position, the positioning rod 26 and the positioning hole 25 on the slide bar 22 are in the same straight line. The positioning rod 26 enters the positioning hole 25 under the action of the spring and is fixed, thereby fixing the slide bar 22. At this time, the user's hands are freed, and it is convenient for the user to press the pressing plate 12 to perform the glue discharge operation. After the glue discharge operation is completed, when it is necessary to make the bottom of the water seepage ring 2 abut against the asphalt pavement, the rectangular frame 21 is slidably installed to make the positioning rod 26 disengage from the positioning hole 25 (when the hemispherical shape of the positioning rod 26 is in the positioning hole 25, the center of the hemispherical body of the positioning rod 26 is still outside the positioning hole 25, so after applying a certain force, the positioning rod 26 can be disengaged from the positioning hole 25), and drive the water seepage meter 1 and the water seepage ring 2 to abut against the asphalt pavement.

[0047] The surface of the slide bar 22 is provided with a glue removal mechanism 30, and the glue removal mechanism 30 includes two storage boxes 31 symmetrically fixedly installed on the surface of the slide bar 22, and the storage boxes 31 are pre-stored with glue removal agents. A connecting pipe 32 connected to the interior is fixedly installed on one side of the storage box 31, and a hollow ring 33 is fixedly sleeved on the surface of the water seepage ring 2. A connecting hole 34 is opened on one side of the ring 33, and a liquid outlet 35 is opened at the bottom of the ring 33, and a filter is fixedly installed in the liquid outlet 35.

[0048] During operation, when the test is completed and the water seepage meter 1 needs to be removed, the plug 24 on the top of the slide rod 22 is twisted and unscrewed to allow the gas to enter the suction cup 23 through the hollow slide rod 22, so that the suction cup 23 loses suction and is easy to pull out. First, connect the connecting tube 32 and the collar 33, then slide the slide rod 22, let the slide rod 22 move the storage box 31 into the rectangular frame 21, and use the rectangular frame 21 to continuously squeeze the storage box 31, forcing the glue remover (which can be white vinegar, isopropyl alcohol, depending on the actual situation) in the storage box 31, and the glue remover enters the collar 33 through the connecting tube 32, and flows to the bonding point between the water seepage ring 2 and the glue through the connecting hole 34 at the bottom of the collar 33, thereby reducing the viscosity of the glue and assisting in removing the water seepage ring 2 from the asphalt pavement. The plug 24 designed as above can quickly remove the suction cup 23 used for positioning, and spray out the glue remover at the same time, thereby assisting the disassembly of the water seepage ring 2, avoiding the water seepage ring 2 being difficult to disassemble after being glued, resulting in difficulty in continuing to use the water seepage instrument 1.

[0049] A counterweight mechanism 40 is provided on one side of the water seepage meter 1 close to the rubber storage ring 11, and the counterweight mechanism 40 includes a hollow counterweight ring 41 fixedly mounted on the water seepage meter 1, and water is pre-stored in the counterweight ring 41; a liquid guide tube 42 connected to the interior is fixedly mounted on one side of the counterweight ring 41, and a sealing plate 43 is slidably connected in the counterweight ring 41, a fixing plate 44 is fixedly mounted on one end of the sealing plate 43, and sealing assemblies 47 are fixedly mounted on the upper and lower ends of the fixing plate 44, and one end of the sealing assembly 47 away from the fixing plate 44 is fixedly connected to the counterweight ring 41, and a groove 45 is provided at the bottom of the push plate 13, and the fixing plate 44 and the push plate 13 are connected by a connecting assembly 46.

[0050] Specifically, the connection assembly 46 includes an electromagnet 461 fixedly mounted on the top of the push plate 13, and a magnetic block 462 is fixedly mounted in the groove 45. The sealing assembly 47 is composed of a plurality of hollow plates that are sealed and slidably connected. A connection plate 50 is fixedly mounted on the surface of the slide bar 22, and the end of the connection plate 50 away from the slide bar 22 is arc-shaped.

[0051] During operation, the weight of the water seepage meter 1 is increased by installing a counterweight ring 41 on the water seepage meter 1 and injecting a cleaning agent (which can be water or can be replaced according to actual needs), thereby eliminating the need for additional counterweight equipment. By designing the counterweight ring 41, the water seepage meter 1 can be kept vertical and stable during testing to ensure the accuracy of the measurement. At the same time, the counterweight ring 41 can increase the center of gravity of the device to prevent tilting. This design integrates the counterweight with the water seepage meter 1, eliminating the need to carry it separately, greatly improving portability.

[0052] At this time, the push plate 13 is at the lowest end, and its groove 45 covers the electromagnet 461 of the fixed plate 44. By energizing the electromagnet 461, the electromagnet 461 and the magnetic block 462 in the groove 45 are attracted to each other and fixed to each other. After spraying the degumming agent, the connecting pipe 32 and the connecting hole 34 are separated, and the liquid guide tube 42 and the connecting hole 34 are connected and installed. At this time, the push plate 13 is pulled, so that when the push plate 13 moves again, it will move with the fixed plate 44, the electromagnet 461, the sealing assembly 47 and the sealing plate 43. The sealing plate 43 pushes the cleaning agent in the counterweight ring 41 into the liquid guide tube 42 and injects it into the ring 33, and then sprays it to the glue on the asphalt road through the liquid outlet hole 35 of the ring 33 to flush the glue, thereby flushing the glue on the ground. The sealing assembly 47 moves with the fixing plate 44 to seal the weight ring 41 well, effectively preventing the detergent in the weight ring 41 from leaking when the fixing plate 44 moves. At this time, the slide bar 22 in the rectangular frame 21 is slid again, so that the connecting plate 50 on the slide bar 22 squeezes the elastic block 27, and the air outlet pipe 28 is aligned with the bonding point between the glue and the asphalt pavement, so as to blow away the residual glue, realize further cleaning of the asphalt pavement, and thus ensure a traceless operation.

[0053] Working principle: When placing the water seepage meter 1, the water seepage meter 1 is carried through the rectangular frame 21, and the slide bar 22 in the rectangular frame 21 is slid, so that the slide bar 22 moves with the suction cup 23 to the asphalt road surface. At this time, the protrusions on both sides of the slide bar 22 will squeeze the elastic block 27 in the rectangular frame 21, so that the gas in the elastic block 27 is sprayed to the asphalt road surface through the air outlet pipe 28, and the asphalt road surface under the suction cup 23 is blown for pre-cleaning. When sliding, the slide bar 22 will continuously squeeze the positioning rod 26 in the rectangular frame 21, so that the positioning rod 26 slides and shrinks into the rectangular frame 21. When the slide bar 22 moves to the appropriate position, the positioning rod 26 and the positioning hole 25 on the slide bar 22 are in the same straight line. The positioning rod 26 enters the positioning hole 25 under the action of the spring and is fixed, thereby fixing the slide bar 22.

[0054] The water seepage meter 1 is placed on the asphalt pavement to be tested, and the water seepage circle 2 at the bottom of the water seepage meter 1 is close to the asphalt pavement. By sliding the push plate 13, the push plate 13 and the pressure plate 12 move from top to bottom in the glue storage ring 11, so that the glue pre-stored in the glue storage ring 11 is squeezed into the fixed ring 15, and flows to the water seepage circle 2 through the arc-shaped sliding ring 14. By installing a plurality of fixed rings 15 and sliding rings 14, the outflowing glue can surround the water seepage circle 2. When the glue discharge operation is completed, when it is necessary to make the bottom of the water seepage circle 2 abut against the asphalt pavement, the rectangular frame 21 is slid and installed, so that the positioning rod 26 is separated from the positioning hole 25, and the water seepage meter 1 and the water seepage circle 2 are driven to abut against the asphalt pavement, and are completely bonded with the glue. Since one end of the sliding ring 14 is closer to the asphalt pavement than the water seepage circle 2, when the water seepage circle 2 moves toward the asphalt pavement, the sliding ring 14 will slide and shrink toward the fixed ring 15. At the same time, since the fixed rod 163 and the top of the glue plate 162 are in contact with each other, the sliding ring 14 will move with the glue plate 162 when it moves, and then the fixed rod 163 will be used to push the glue plate 162 in the sliding ring 14, so that the glue plate 162 slides along the direction of the opening of the hollow groove 161, and the glue plate 162 that slides out will come into contact with the glue.

[0055] When the test is completed and the water seepage meter 1 needs to be removed, turn and unscrew the plug 24 on the top of the slide rod 22 to allow the gas to enter the suction cup 23 through the hollow slide rod 22, so that the suction cup 23 loses suction and is easy to pull out. First connect the connecting tube 32 and the ring 33, then slide the slide rod 22, let the slide rod 22 move the storage box 31 into the rectangular frame 21, and use the rectangular frame 21 to continuously squeeze the storage box 31, forcing the glue remover in the storage box 31 to enter the ring 33 through the connecting tube 32, and flow to the bonding point between the water seepage ring 2 and the glue through the connecting hole 34 at the bottom of the ring 33, thereby reducing the viscosity of the glue and assisting in removing the water seepage ring 2 from the asphalt pavement.

[0056] At this time, the push plate 13 is at the lowest end, and its groove 45 covers the electromagnet 461 of the fixed plate 44. By energizing the electromagnet 461, the electromagnet 461 and the magnetic block 462 in the groove 45 are attracted to each other and fixed to each other. After spraying the degumming agent, the connecting pipe 32 and the connecting hole 34 are separated, and the liquid guide tube 42 and the connecting hole 34 are connected and installed. At this time, the push plate 13 is pulled, so that when the push plate 13 moves again, it will move with the fixed plate 44, the electromagnet 461, the sealing assembly 47 and the sealing plate 43. The sealing plate 43 pushes the cleaning agent in the counterweight ring 41 into the liquid guide tube 42 and injects it into the ring 33, and then sprays it to the glue on the asphalt road surface through the liquid outlet hole 35 of the ring 33 to flush the glue. At this time, the slide bar 22 in the rectangular frame 21 is slid again, so that the connecting plate 50 on the slide bar 22 squeezes the elastic block 27, and the air outlet pipe 28 is aligned with the bonding point between the glue and the asphalt road surface, so as to blow away the residual glue.
