Description

Technical Field

[0001] The present invention belongs to the technical field of asphalt pavement permeameters, and specifically relates to a device for detecting the permeation performance of asphalt pavements. Background Art

[0002] An asphalt pavement permeameter is a special device for measuring the permeation performance of asphalt pavements. It is mainly used to evaluate the drainage capacity of roads to ensure that asphalt pavements can effectively drain water under rainy or wet conditions, thereby improving driving safety and the service life of roads. The asphalt pavement permeameter mainly consists of a permeation ring, a measuring device, a counterweight, and water. By placing the permeation ring on the asphalt pavement and ensuring its airtightness, a certain amount of water is injected into the permeation ring and timing is started, and the decrease in water level is recorded to calculate the water permeability.

[0003] Before the existing asphalt pavement permeameters are used for testing, the permeation ring needs to be placed on the asphalt pavement to be tested first, and then a layer of sealant is applied around the permeation ring to ensure airtightness during the test. When using the glue, a glue gun is also needed for auxiliary operation, and a large number of devices need to be carried, which brings great inconvenience to outdoor testing; at the same time, the sprayed glue is also difficult to seal the permeation ring well and requires continuous adjustment many times, greatly reducing the test efficiency.

[0004] Therefore, the present invention provides a device for detecting the permeation performance of asphalt pavements. Summary of the Invention

[0009] Further, two symmetrically arranged elastic blocks are fixedly installed inside the rectangular frame. The inside of the elastic block is hollow. An air outlet pipe communicating with the inside is fixedly installed at the bottom of the elastic block. One end of the air outlet pipe away from the elastic block is aligned with the bottom of the suction cup.

[0010] Further, a glue - removing mechanism is arranged on the surface of the sliding rod. The glue - removing mechanism includes two symmetrically fixedly installed storage boxes on the surface of the sliding rod. The storage boxes store glue - removing agent in advance. A connecting pipe communicating with the inside is fixedly installed on one side of the storage box. A hollow sleeve ring is fixedly sleeved on the surface of the water seepage ring.

A liquid guide pipe communicating with the inside is fixedly installed on one side of the weight ring. A sealing plate is slidably connected inside the weight ring.

[0014] Further, a connecting plate is fixedly installed on the surface of the sliding rod. One end of the connecting plate away from the sliding rod is arc - shaped.

[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 seepage circle needs to be in contact with 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 seepage circle to contact 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 seepage performance detection device described in the present invention increases the weight of the seepage meter by installing a counterweight ring on the seepage meter and injecting a cleaning agent, so that there is no need to additionally set up a counterweight device. By designing the counterweight ring, the seepage meter 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. This design integrates the counterweight with the seepage meter, eliminating the need to carry it separately, greatly improving portability. When the push plate moves, it will drive the sealing component and the sealing plate to move together. The sealing plate pushes the cleaning agent in the counterweight ring into the liquid guide pipe and then injects it into the collar, and then sprays it onto the glue on the asphalt pavement through the liquid outlet holes of the collar to wash the glue, thereby washing the glue on the ground clean. Then slide the sliding rod in the rectangular frame so that the connecting plate on the sliding rod presses the elastic block and aligns the air outlet pipe with the bonding part of the glue and the asphalt pavement, so as to blow away the remaining glue, realizing further cleaning of the asphalt pavement, and thus ensuring a trace-free operation.

[0039] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] As Figures 1 to 10 shown, a device for detecting the water permeability performance of an asphalt pavement according to an embodiment of the present invention includes a permeability tester 1, and a permeability ring 2 is fixedly installed at the bottom of the permeability tester 1; a glue discharging mechanism 10 for storing glue is provided on the permeability tester 1; the glue discharging mechanism 10 includes a glue storage ring 11 fixedly installed on the permeability tester 1, a pressing plate 12 is slidably connected inside the glue storage ring 11, a pushing plate 13 passing through the glue storage ring 11 is fixedly installed on the top of the pressing plate 12, a plurality of fixed rings 15 are fixedly installed on one side of the permeability tester 1 close to the permeability ring 2, the fixed rings 15 are communicated with the glue storage ring 11, the outer surface of the fixed ring 15 is slidably connected with a sliding ring 14, both the fixed ring 15 and the sliding ring 14 are arc-shaped, and the port of the sliding ring 14 is close to the bottom of the permeability ring 2;

[0041] Specifically, a glue spreading component 16 for assisting in spreading glue is provided on one side of the water seepage meter 1 close to the fixing ring 15. The glue spreading component 16 includes a plurality of arc-shaped fixing rods 163 fixedly installed at the bottom of the water seepage meter 1. A hollow groove 161 is formed 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 formed by rotatably connecting a plurality of rectangular plates through a rotating shaft. The top of the glue spreading plate 162 is in contact with the fixing rod 163.

[0042] During operation, the water seepage meter 1 is placed on the asphalt pavement to be tested. At this time, the water seepage ring 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 drives the pressing plate 12 to move downward in the glue storage ring 11, so as to squeeze the glue pre-stored in the glue storage ring 11 into the fixing ring 15, and flow to the water seepage ring 2 through the arc-shaped sliding ring 14. By installing a plurality of fixing rings 15 and sliding rings 14, the flowing glue can surround the water seepage ring 2, thereby improving the glue spraying efficiency and efficiently spraying the glue around the water seepage ring 2.

[0043] After the glue is sprayed, the water seepage meter 1 and the water seepage ring 2 are moved again so that the water seepage ring 2 is in contact with the asphalt pavement and completely adhered to 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 towards the asphalt pavement, the sliding ring 14 will slide and contract towards the fixing ring 15. At the same time, since the fixing rod 163 is in contact with the top of the glue spreading plate 162, when the sliding ring 14 moves, it will drive the glue spreading plate 162 to move, and then use the fixing rod 163 to push the glue spreading plate 162 in the sliding ring 14, so that the glue spreading plate 162 slides along the opening direction of the hollow groove 161 (it should be noted that the glue spreading plate 162 is designed as a plurality of rectangular plates connected by a rotating shaft to facilitate sliding out of the hollow groove 161). The slid-out glue spreading plate 162 will contact the glue and move and spread the sprayed glue to avoid the situation that the glue can only be sprayed to the corresponding place of the sliding ring 14, resulting in no glue at the gap between the two sliding rings 14 and poor sealing effect of the water seepage ring 2.

[0044] Through the designed glue discharging mechanism 10 and glue spreading component 16, when testing the asphalt pavement outdoors, there is no need to carry glue and a glue spraying gun additionally, which greatly reduces the equipment to be carried and brings great convenience to the test; at the same time, the surrounding spraying of glue and the auxiliary glue spreading can better seal the water seepage ring 2 and avoid the situation of uneven glue spreading and water leakage.

[0045] Two positioning mechanisms 20 are symmetrically arranged on the surface of the seepage meter 1. A rectangular frame 21 is fixedly connected to the positioning mechanism 20 and the seepage meter 1. A sliding rod 22 is slidably connected inside the rectangular frame 21. A suction cup 23 is fixedly installed at the bottom of the sliding rod 22. The inside of the sliding rod 22 is hollow and communicates with the suction cup 23. A plug column 24 is threadedly connected to the top of the sliding rod 22; a number of hemispherical positioning holes 25 are formed on both sides of the sliding rod 22. A positioning rod 26 is slidably connected inside the rectangular frame 21 through a spring. One 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 communicating with the inside is fixedly installed at the bottom of the elastic block 27. One 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 seepage meter 1, the seepage meter 1 is carried through the rectangular frame 21, and the sliding rod 22 inside the rectangular frame 21 is slid, so that the sliding rod 22 drives the suction cup 23 to move towards the asphalt pavement. At this time, the protrusions on both sides of the sliding rod 22 will squeeze the elastic block 27 inside the rectangular frame 21, so that the gas inside the elastic block 27 is sprayed towards the asphalt pavement through the air outlet pipe 28, and the asphalt pavement under the suction cup 23 is blown and pre-cleaned to reduce the residue of impurities and facilitate the adsorption of the suction cup 23 and the asphalt pavement. When the sliding rod 22 slides, it will continuously squeeze the positioning rod 26 inside the rectangular frame 21, so that the positioning rod 26 slides and contracts into the rectangular frame 21. When the sliding rod 22 moves to a suitable position, the positioning holes 25 on the sliding rod 22 and the positioning rod 26 are on 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 sliding rod 22. At this time, the hands of the user are liberated, which is convenient for the user to press the pressing plate 12 for glue discharging operation. When the glue discharging operation is completed and it is necessary to make the bottom of the seepage ring 2 abut against the asphalt pavement, the rectangular frame 21 is slidably installed, so that the positioning rod 26 disengages from the positioning hole 25 (when the hemispherical shape of the positioning rod 26 is inside the positioning hole 25, the center of the hemisphere of the positioning rod 26 is still outside the positioning hole 25, so after applying a certain force, the positioning rod 26 can disengage from the positioning hole 25), and the seepage meter 1 and the seepage ring 2 are driven to abut against the asphalt pavement.

[0047] A glue removing mechanism 30 is arranged on the surface of the sliding rod 22. The glue removing mechanism 30 includes two storage boxes 31 symmetrically and fixedly installed on the surface of the sliding rod 22. The storage boxes 31 pre-store glue remover. A connecting pipe 32 communicating with the inside is fixedly installed on one side of the storage box 31. A hollow ring 33 is fixedly sleeved on the surface of the seepage ring 2. A connecting hole 34 is formed on one side of the ring 33. A liquid outlet hole 35 is formed at the bottom of the ring 33. A filter screen is fixedly installed in the liquid outlet hole 35.

[0048] During operation, when it is necessary to remove the water seepage meter 1 after the test is completed, turn and screw out the plug post 24 at the top of the sliding rod 22, so that gas enters the suction cup 23 through the hollow sliding rod 22, causing the suction cup 23 to lose suction and facilitating extraction. First, connect the connecting pipe 32 and the collar 33, then slide the sliding rod 22, so that the sliding rod 22 drives the storage box 31 to move into the rectangular frame 21. Use the rectangular frame 21 to continuously squeeze the storage box 31, forcing the degreaser (which can be white vinegar, isopropyl alcohol, depending on the actual situation) in the storage box 31. The degreaser enters the collar 33 through the connecting pipe 32 and flows through the connecting hole 34 at the bottom of the collar 33 to the bonding place between the water seepage ring 2 and the glue, thereby reducing the viscosity of the glue and assisting in removing the water seepage ring 2 from the asphalt pavement. Through the above-designed plug post 24, the suction cup 23 for positioning can be quickly removed, and at the same time, the degreaser is ejected, thereby assisting in the disassembly work of the water seepage ring 2 and avoiding the difficulty in disassembling the water seepage ring 2 after being bonded with glue, resulting in the difficulty in continuing to use the water seepage meter 1.

[0049] On one side of the water seepage meter 1 close to the glue storage ring 11, a weight mechanism 40 is provided. The weight mechanism 40 includes a hollow weight ring 41 fixedly installed on the water seepage meter 1. Water is pre-stored in the weight ring 41. A liquid guide pipe 42 communicating with the inside is fixedly installed on one side of the weight ring 41. A sealing plate 43 is slidably connected in the weight ring 41. One end of the sealing plate 43 is fixedly installed with a fixing plate 44. Sealing components 47 are fixedly installed at the upper and lower ends of the fixing plate 44. The end of the sealing component 47 away from the fixing plate 44 is fixedly connected to the weight ring 41. A groove 45 is opened at the bottom of the push plate 13. The fixing plate 44 and the push plate 13 are connected by a connecting component 46.

[0050] Specifically, the connecting component 46 includes an electromagnet 461 fixedly installed in the groove 45 of the push plate 13, and a magnetic block 462 is fixedly installed at the top of the fixing plate 44. The sealing component 47 is composed of a plurality of hollow plates that are hermetically and slidably connected. An arc-shaped connecting plate 50 is fixedly installed on the surface of the sliding rod 22.

[0051] During operation, by installing the weight ring 41 on the water seepage meter 1 and injecting a cleaning agent (which can be water or can be replaced according to actual requirements), the weight of the water seepage meter 1 is increased, and thus there is no need to additionally set up a weight device. By designing the weight ring 41, the water seepage meter 1 can be kept vertical and stable during the test to ensure the accuracy of measurement. At the same time, the weight ring 41 can increase the center of gravity of the device to prevent tilting. This design integrates the weight with the water seepage meter 1, eliminating the need to carry it separately and greatly improving the portability.

[0052] At this time, the push plate 13 is at the lowest end, and its groove 45 covers the electromagnet 461 on the fixed plate 44. By energizing the electromagnet 461, the electromagnet 461 and the magnetic block 462 at the top of the fixed plate 44 attract each other with opposite polarities and are fixed to each other. After spraying the degreaser, the connecting pipe 32 is detached from the connecting hole 34, and the liquid guide pipe 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, it will drive the fixed plate 44, the electromagnet 461, the sealing assembly 47 and the sealing plate 43 to move together. The sealing plate 43 pushes the cleaner in the counterweight ring 41 into the liquid guide pipe 42 and then injects it into the collar 33, and then sprays it onto the glue on the asphalt pavement through the liquid outlet hole 35 of the collar 33 to wash the glue, so as to wash the glue on the ground clean. The sealing assembly 47 moves with the fixed plate 44, which can well seal the counterweight ring 41 and effectively prevent the cleaner in the counterweight ring 41 from leaking when the fixed plate 44 moves. At this time, the sliding rod 22 in the rectangular frame 21 is further slid, so that the connecting plate 50 on the sliding rod 22 squeezes the elastic block 27, and the air outlet pipe 28 is aligned with the bonding place of the glue and the asphalt pavement, so as to blow away the remaining glue, realize the further cleaning of the asphalt pavement, and further ensure trace-free operation.

[0053] Working principle: When placing the permeameter 1, the permeameter 1 is carried by the rectangular frame 21, and the sliding rod 22 in the rectangular frame 21 is slid, so that the sliding rod 22 drives the suction cup 23 to move towards the asphalt pavement. At this time, the protrusions on both sides of the sliding rod 22 will squeeze the elastic block 27 in the rectangular frame 21, so that the gas in the elastic block 27 is sprayed towards the asphalt pavement through the air outlet pipe 28 to blow and pre-clean the asphalt pavement under the suction cup 23. When the sliding rod 22 slides, it will continuously squeeze the positioning rod 26 in the rectangular frame 21, so that the positioning rod 26 slides and contracts into the rectangular frame 21. When the sliding rod 22 moves to a suitable position, the positioning hole 25 of the positioning rod 26 on the sliding rod 22 is in the same straight line, and the positioning rod 26 enters the positioning hole 25 under the action of the spring and is fixed, thereby fixing the sliding rod 22.

[0054] By placing the seepage meter 1 on the asphalt pavement to be tested, the seepage circle 2 at the bottom of the seepage meter 1 is close to the asphalt pavement at this time. By sliding the push plate 13, the push plate 13 drives the pressing plate 12 to move downward in the glue storage ring 11, so as to squeeze the glue pre-stored in the glue storage ring 11 into the fixed ring 15 and flow to the seepage circle 2 through the arc-shaped sliding ring 14. By installing a number of fixed rings 15 and sliding rings 14, the flowing glue can surround the seepage circle 2. When the glue discharging operation is completed and it is necessary to make the bottom of the seepage circle 2 abut against the asphalt pavement, the rectangular frame 21 is slidably installed, so that the positioning rod 26 disengages from the positioning hole 25, and drives the seepage meter 1 and the seepage circle 2 to abut against the asphalt pavement and be completely bonded with the glue. Since one end of the sliding ring 14 is closer to the asphalt pavement than the seepage circle 2, when the seepage circle 2 moves towards the asphalt pavement, the sliding ring 14 will slide and contract towards the fixed ring 15. At the same time, since the fixed rod 163 is in contact with the top of the glue spreading plate 162, when the sliding ring 14 moves, it will drive the glue spreading plate 162 to move, and then use the fixed rod 163 to push the glue spreading plate 162 in the sliding ring 14, so that the glue spreading plate 162 slides along the opening direction of the hollow groove 161, and the sliding out glue spreading plate 162 will contact the glue.

[0055] When it is necessary to remove the seepage meter 1 after the test is completed, turn and screw out the plug column 24 at the top of the sliding rod 22, so that the gas enters the suction cup 23 through the hollow sliding rod 22, making the suction cup 23 lose suction and facilitating pulling out. First, connect the connecting pipe 32 and the collar 33, and then slide the sliding rod 22, so that the sliding rod 22 drives the storage box 31 to move into the rectangular frame 21, and use the rectangular frame 21 to continuously squeeze the storage box 31, forcing the remover in the storage box 31. The remover enters the collar 33 through the connecting pipe 32 and flows to the bonding place of the seepage circle 2 and the glue through the connecting hole 34 at the bottom of the collar 33, so as to reduce the viscosity of the glue and assist in removing the seepage circle 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 on the fixed plate 44. By energizing the electromagnet 461, the electromagnet 461 and the magnetic block 462 at the top of the fixed plate 44 are attracted by opposite sex and fixed to each other. After spraying the remover, disconnect the connecting pipe 32 from the connecting hole 34 and connect and install the liquid guide pipe 42 and the connecting hole 34. At this time, pull the push plate 13, so that when the push plate 13 moves, it will drive the fixed plate 44, the electromagnet 461, the sealing assembly 47 and the sealing plate 43 to move together. The sealing plate 43 pushes the cleaner in the counterweight ring 41 into the liquid guide pipe 42 and then injects it into the collar 33, and then sprays it onto the glue on the asphalt pavement through the liquid outlet hole 35 of the collar 33 to wash the glue. At this time, slide the sliding rod 22 in the rectangular frame 21 again, so that the connecting plate 50 on the sliding rod 22 squeezes the elastic block 27 and aligns the air outlet pipe 28 with the bonding place of the glue and the asphalt pavement, so as to blow away the remaining glue.
