Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of asphalt pavement detection, and particularly relates to a water permeation detection device for asphalt pavement. BACKGROUND

[0002] The main purpose of asphalt pavement detection is to evaluate the quality, durability and stability of the pavement, and to find potential problems so as to take corresponding repair measures, prolong the service life of the pavement, improve traffic safety, and save maintenance costs. The detection projects include pavement flatness detection, pavement thickness detection, pavement structure strength detection, crack and pit detection, and water permeability detection. The water permeability detection is generally performed by using a pavement water permeation instrument.

[0003] An application No. CN202011544647.2 discloses an asphalt pavement detection device, which comprises a lower base, a connecting pipe is arranged at the upper end of the lower base, two weight increasing blocks are symmetrically arranged at the outer side of the connecting pipe, a fixing structure is arranged at the upper end of the two weight increasing blocks, an extrusion block is arranged at the lower end of each weight increasing block, two fixing columns are symmetrically arranged at the lower end of the fixing structure, two connecting plates are symmetrically arranged on the outer wall of the fixing structure, and a No. 2 spring is arranged at the upper end of each connecting plate. The asphalt pavement detection device disclosed by the application belongs to the field of detection equipment. The accommodating groove and the leakage hole arranged on the lower base can facilitate the storage of sealing glue. The extrusion block arranged at the lower end of the weight increasing block can facilitate the extrusion of the sealing glue, thereby simplifying the complexity of asphalt pavement detection and improving the efficiency of asphalt pavement detection.

[0004] However, the sealing glue is extruded by the weight increasing block in the application, which simplifies the complexity of asphalt pavement detection. However, the weight increasing block increases the overall weight of the device, which is not convenient for carrying and using.

[0005] An application No. CN202011198684.2 discloses an asphalt pavement water permeation detection device. The inner ring and the outer ring are combined to form a sealing area. The cooperation between the limiting rod on the putty cylinder and the limiting groove at the lower end of the hydraulic rod enables the putty cylinder to rotate and move upward when extruding putty, simulating the process of applying putty. An arc-shaped push plate is connected to the lower end of the putty cylinder to evenly apply putty. The vertical relative movement between the fan-shaped plate and the inner and outer rings removes the ring-shaped sealing putty from the ring-shaped area. The rotation of the self-locking motor rotates the liquid injection device above the sealing putty ring, and then performs water permeation detection. Two sets of detection devices work simultaneously, and the next measurement point can be detected by rotating the two sets of detection devices at the center support rod.

[0006] The patent has high automation degree but high cost, large size and is inconvenient to carry and use.

[0007] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. SUMMARY

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the technical scheme in the embodiments of the present application to make clear and complete description, obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

When a component is referred to as "fixed to" another component, it can be directly on the other component or there can be a middle component. When a component is referred to as "connected to" another component, it can be directly connected to the other component or there can be a middle component. When a component is referred to as "provided on" another component, it can be directly provided on the other component or there can be a middle component. The terms "vertical", "horizontal", "left", "right" and the like used herein are only for illustrative purposes.

[0043] As Figures 1 to 12As shown, the water permeability detection device for asphalt pavement provided by the present application comprises a detection mechanism 1 for detecting the asphalt pavement, and a supporting mechanism 2 for supporting the detection mechanism 1, which avoids the detection mechanism 1 from being skewed during the detection process and affecting the detection effect; the detection mechanism 1 comprises a measuring cylinder 12 for storing water and visually observing the water level drop so as to calculate the water permeability of the asphalt pavement; the supporting mechanism 2 comprises a base 23, a limiting frame 21, and a water injection assembly 22 for injecting water into the measuring cylinder 12, which can reduce the labor strength consumed by manually injecting water into the measuring cylinder 12 from the upper opening of the measuring cylinder 12 during the detection process, reduce the complexity of the detection process, and also can perform the pre-watering work before reaching the detection area, thereby accelerating the detection efficiency.

[0044] The water injection assembly 22 comprises a capsule 221, a liquid delivery pipe 2211 connected with the capsule 221, a connecting pipe 2212 connected with the liquid delivery pipe 2211, a horizontal piece 2213 connected with the connecting pipe 2212, a liquid discharge pipe 2214 connected with the horizontal piece 2213, a liquid discharge opening 2215 formed in the liquid discharge pipe 2214, and a valve 1 installed in the connecting pipe 2212; the liquid delivery pipe 2211 is communicated with the measuring cylinder 12, and a valve 2 is installed in the liquid delivery pipe 2211; the valve 1 is an electric control valve, and the valve 2 is a one-way valve.

[0045] When the capsule 221 is pressed, the water in the capsule 221 is discharged into the measuring cylinder 12 through the liquid delivery pipe 2211 and the horizontal piece 2213, which avoids manually adding water into the measuring cylinder 12, increases the labor participation degree, and causes the detection process to be complicated; in addition, under the action of the valve 1 and the valve 2, the water in the capsule 221 enters the measuring cylinder 12, and when the detection is needed, the water in the measuring cylinder 12 enters the liquid discharge pipe 2214 through the connecting pipe 2212 and the horizontal piece 2213, and is discharged through the liquid discharge opening 2215, thereby optimizing the step of manually injecting water into the measuring cylinder 12 in the prior art, and improving the detection efficiency.

[0046] When the capsule 221 is pressed, the water enters the horizontal piece 2213, and since a porous plate 22131 is fixedly installed on the horizontal piece 2213, a plurality of small holes are formed in the porous plate 22131, a sliding plate 22132 is slidably connected to the horizontal piece 2213, an extension piece 22133 is fixedly installed on the sliding plate 22132, a sliding piece 221321 is slidably connected to the sliding plate 22132, a liquid leakage opening 221322 is formed in the sliding piece 221321, and a convex rod 22141 is fixedly installed on the liquid discharge pipe 2214; the extension piece 22133 is fixedly installed on the inner wall of the horizontal piece 2213, and the end of the horizontal piece 2213 away from the capsule 221 is transparent, so that the water in the horizontal piece 2213 can be observed.

[0047] When the water liquid enters the inside of the horizontal piece 2213 through the connecting pipe 2212, the sliding plate 22132 is pushed to move to the direction of the liquid discharge pipe 2214 under the impact of the water liquid, and the inside of the horizontal piece 2213 is filled through the porous plate 22131 at the same time. At this time, the sliding piece 221321 moves on the sliding plate 22132 under the action of the top rod, so that the liquid leakage port 221322 is exposed. At this time, the water liquid continuously entering the inside of the horizontal piece 2213 flows outwards under the action of the liquid leakage port 221322 and the liquid discharge pipe 2214. When the water liquid injection in the measuring cylinder 12 is completed, the extrusion capsule one 221 is stopped, and the water liquid in the horizontal piece 2213 flows out after the water liquid stops entering. At this time, the valve one controls the water liquid flowing out of the measuring cylinder 12 to carry out the water seepage detection on the road surface.

[0048] In addition, if the levelness of the horizontal piece 2213 and the whole device is within the qualified range, the water liquid between the porous plate 22131 and the transparent end of the horizontal piece 2213 forms a water film, which cannot pass through the small holes on the porous plate 22131, and water will be stored in the horizontal piece 2213. It can be observed through the transparent end of the horizontal piece 2213. If the levelness of the horizontal piece 2213 and the whole device is unqualified, the water liquid cannot form a water film, which is convenient for measuring the levelness of the detection area and improving the detection effect. It should be noted that the volume of the horizontal piece 2213 is small, and the amount of water contained is small, so that too much water liquid cannot flow out, which affects the water seepage detection effect on the road surface.

[0049] That is, the extrusion capsule one 221 makes the water liquid enter the horizontal piece 2213 and the measuring cylinder 12. The horizontal piece 2213 can detect the levelness of the device, and the water liquid in the measuring cylinder 12 is discharged through the liquid discharge port 2215 to enter the inside of the detection seat 2326 for detection, which has good use effect. By controlling the height of the horizontal piece 2213 (that is, the distance between the transparent end of the horizontal piece 2213 and the end opposite to the transparent end), the detection range of the levelness of the road surface can be adjusted, which has good use effect.

[0050] To supplement the above, if foreign matter enters the upper end of the measuring cylinder 12 during the draining process, it will affect the outflow of water and thus the accuracy of the test results. Therefore, the measuring cylinder 12 is further provided with a cover plate 11 that closes the inlet of the measuring cylinder 12. The cover plate 11 is composed of a fixed plate 111 that is detachably connected to the measuring cylinder 12, a through hole 112 opened in the fixed plate 111, a rotating shaft 113 rotatably installed on the fixed plate 111, and a rotating plate 114 fixedly installed on the rotating shaft 113. The fixed plate 111 can block large foreign matter from entering the interior of the measuring cylinder 12, preventing the water inside the measuring cylinder 12 from flowing out. In addition, the rotating shaft 113 can drive the rotating plate 114 to rotate, allowing the rotating plate 114 to move below the through hole 112, completely isolating the measuring cylinder 12 from the outside. This has the advantage that before the extrusion of the first capsule 221, the rotating shaft 113 is rotated to move the rotating plate 114 below the through hole 112, and then the first capsule 221 is extruded. At this time, due to the existence of air pressure in the measuring cylinder 12, the water will preferentially enter the horizontal piece 2213 to detect the levelness of the detection area, and at the same time, water resources will not be wasted. After the levelness detection of the horizontal piece 2213 is completed, the rotating shaft 113 is rotated again to move the rotating plate 114 away from below the through hole 112, allowing the water in the first capsule 221 to normally enter the measuring cylinder 12. On the one hand, the cover plate 11 can block foreign matter from entering the interior of the measuring cylinder 12, affecting the outflow of water from the measuring cylinder 12. On the other hand, the levelness detection is separated from the water injection of the measuring cylinder 12, avoiding the situation where the levelness is unqualified and the water in the first capsule 221 is discharged, resulting in the inability to detect and the waste of water resources.

[0051] To avoid the unevenness or cracks in the road surface causing the water to flow to the non-detection area, affecting the detection effect of the road surface, it is usually necessary to seal the space between the base 23 and the road surface after the base 23 contacts the road surface, to ensure the accuracy of the detection results.

[0052] The lower bottom plate 212 is fixedly installed with a base 23, the base 23 is provided with a cavity 231, the cavity 231 is communicated with a second liquid outlet pipe 2221, the second liquid outlet pipe 2221 is communicated with a second capsule 222, the second capsule 222 is fixedly connected with a connecting rod 2222, one end of the connecting rod 2222 is connected with the upper end of the second capsule 222, the upper end of the second capsule 222 is the end close to the measuring cylinder 12, the connecting rod 2222 is slidably connected with a rotating block 232, the rotating block 232 is provided with a liquid inlet 2321 on the side close to the base 23, the rotating block 232 is provided with a sliding groove 2322 on the side close to the connecting rod 2222, the rotating block 232 is provided with a side liquid outlet 2323 on the side away from the base 23, the rotating block 232 is provided with an end liquid outlet 233 on the side away from the connecting rod 2222, the base 23 is provided with a glue outlet matched with the position of the liquid inlet 2321; the rotating block 232 is slidably connected with the connecting rod 2222 through the sliding groove 2322.

[0053] When the first extrusion capsule 221 is extruded, the second extrusion capsule 222 is also extruded synchronously, so that the sealant in the second extrusion capsule 222 is discharged into the base 23 through the second liquid outlet 2221, and then enters the rotating block 232 through the glue outlet and the liquid inlet 2321, and is discharged through the end liquid outlet 233 and the side liquid outlet 2323. The sealant is discharged outward through the end liquid outlet 233 and the side liquid outlet 2323, so that the sealing area is larger and the sealing effect is better.

[0054] In addition, when the second extrusion capsule 222 is compressed, the connecting rod 2222 is driven to move, and the connecting rod 2222 drives the rotating block 232 to move downward, so that the sealant is prevented from diffusing into the detection area and affecting the water seepage detection of the asphalt pavement. That is to say, when the first extrusion capsule 221 and the second extrusion capsule 222 are extruded, the first extrusion capsule 221 stores water and detects the levelness, and the second extrusion capsule 222 discharges the sealant for sealing. The use is simple, the complexity of the asphalt pavement detection is simplified, and the efficiency of the asphalt pavement detection is improved.

[0055] It should be noted that the guide 2324 is fixedly installed on the side of the rotating block 232 away from the base 23, the detection seat 2326 is communicated with the liquid outlet 2215, the rotating block 2325 is fixedly installed on the detection seat 2326, the arc-shaped groove 23251 is formed in the rotating block 2325, and the arc-shaped groove 23251 is in sliding connection with the guide 2324. The baffle 2327 is in sliding connection with the detection seat 2326, and the baffle 2327 moves into the detection seat 2326 under the block of the ground when the detection seat 2326 contacts the ground. The baffle 2327 can further prevent the sealant from penetrating into the detection seat 2326 and affecting the water seepage detection of the water in the detection seat 2326 and the ground. The reset member is arranged between the baffle 2327 and the detection seat 2326, and is used to reset the baffle 2327. The reset member can be a spring.

[0056] When the sealant in the second extrusion capsule 222 is discharged to the base 23, the liquid inlet 2321 and the glue outlet are not coincident at this time, and the sealant exists in the cavity 231 of the base 23. The connecting rod 2222 drives the rotating block 232 to move downward, and the rotating block 232 rotates through the sliding groove 2322 under the limiting and guiding of the guide 2324 and the arc-shaped groove 23251. At this time, the liquid inlet 2321 and the glue outlet are opposite to each other, the sealant in the cavity 231 can flow out, the sealing of the sealant between the ground and the base 23 can be triggered, the direct glue discharge is avoided, the detection area cannot meet the detection condition, and the sealant is wasted. In addition, one side of the rotating block 232 is attached to the rotating block 2325, and the rotating block 232 can scrape off the impurities on the side of the rotating block 2325 when the rotating block 232 moves downward, so as to avoid affecting the use effect of the detection seat 2326.

[0057] When the extrusion capsules 221 and 222 are watered and sealed, on the one hand, the water is discharged into the horizontal part 2213 to detect the levelness of the detection area, and on the other hand, the rotating block 232 can be moved to clean the side surface of the rotating block 2325, so as to avoid the influence of the residual sealant or other impurities on the rotating block 2325 on the water seepage detection of the road surface. After the preparation work of adding glue and water is completed, the application only needs to be placed in the detection position, and then the upper top plate 211 is pressed down to complete the water injection, sealing, level detection and water seepage detection. It is convenient to use and easy to operate.

[0058] It should be noted that the volume of the capsule 221 is greater than that of the capsule 222 to meet the use requirements. When the capsules 221 and 222 are extruded, the limit frame 21 is arranged to drive the capsules 221 and 222 to move synchronously and reset. The limit frame 21 comprises: the upper top plate 211 fixedly installed at both ends of the capsules 221 and 222, the lower bottom plate 212, the positioning rod 213 fixedly connected to the lower bottom plate 212, the spring 214 wound on the positioning rod 213, and the two ends of the spring 214 are fixedly connected with the upper top plate 211 and the lower bottom plate 212, respectively. The positioning rod 213 is slidably connected with the upper top plate 211.

[0059] That is, the capsules 221 and 222 are extruded synchronously under the action of the upper top plate 211, which is more convenient to use. When the capsules 221 and 222 are extruded, the spring 214 deforms. When the objects in the capsules 221 and 222 are discharged, the extrusion of the capsules 221 and 222 is stopped, and the spring 214 resets to drive the capsules 221 and 222 to reset, so as to facilitate the addition of materials to the inside of the capsules 221 and 222. Under the action of the positioning rod 213, the capsules 221 and 222 can be limited during movement to avoid uneven compression of the capsules 221 and 222. During actual detection, only artificial standing on the upper top plate 211 is needed to complete the basis of the materials in the capsules 221 and 222 by relying on gravity. It is very convenient to use, and the size is small, which is convenient to carry.

[0060] As a further extension of this application, a float plate 121 is movably connected to the measuring cylinder 12. A sensor 122 is fixedly installed on both the float plate 121 and the measuring cylinder 12. The sensor 122 is a capacitive proximity sensor. The measuring cylinder 12 is fixedly installed on the surface of the upper top plate 211. When water enters the measuring cylinder 12, the float plate 121 floats up under the action of the water. At the same time, the sensor 122 on the float plate 121 and the sensor 122 on the side wall of the measuring cylinder 12 move closer and further away in turn, and an alarm is triggered when they approach each other. On the one hand, the number of alarms from the sensor 122 reminds the staff of the amount of water inside the measuring cylinder 12. On the other hand, when water flows out of the measuring cylinder 12, it can remind the staff of the amount of water flowing out, so that the staff can make the statistical results more accurate.

[0061] like Figure 12 The sensors 122 shown are symmetrically and alternately arranged on the measuring cylinder 12 to avoid multiple sets of sensors 122 being installed on one side of the measuring cylinder 12, which would result in an excessive difference in structural strength between the two sides of the measuring cylinder 12. In other words, when the bladder 221 is squeezed, on the one hand, water enters the measuring cylinder 12 to prepare for detection, and on the other hand, the water pushes the float 121 to move inside the measuring cylinder 12. Under the action of the sensors 122, an alarm is triggered to reflect the amount of water inside the measuring cylinder 12. The operation is simple and the effect is good.

[0062] In addition, the cover plate 11 can also prevent foreign objects from affecting the float plate 121, and avoid the float plate 121 from being affected by foreign objects, which would obstruct its floating or movement and thus affect the alarm, resulting in a decrease in the accuracy of the detection results.
