Description

Technical Field

[0001] The invention relates to the technical field of water seepage detection during asphalt construction, and in particular to a device for detecting water seepage during asphalt construction of road pavement. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder can effectively improve the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors. Therefore, asphalt pavement is the most common pavement on highways at present. In the construction of asphalt pavement, the water permeability coefficient of asphalt pavement directly affects the performance of highways.

[0003] Chinese patent CN213600552U discloses a road pavement asphalt construction water seepage detection device, comprising a base and a top plate, wherein the top plate is installed above the base, and connecting rods are fixedly installed on both sides of the bottom of the top plate near the center. The device for detecting water seepage during asphalt construction on a road surface, when the cylinder is working, can drive the upper top plate to move downward, so that the water outlet pipe can be close to the ground, and then the telescopic rod can be moved downward to make the humidity sensor close to the ground, and the liquid inside the water tank will flow into the top of the asphalt on the road surface through the water outlet pipe, and the water will flow to the outside of the humidity sensor. After the humidity sensor senses the clean water, the solenoid valve works, thereby cutting off the water outlet pipe. When the water level inside the water tank drops, the liquid level sensor can sense the dropped water level inside the water tank, thereby detecting the degree of water seepage during asphalt construction on the road surface, and thus accurately detecting the water seepage of asphalt on the road surface. The above-mentioned related technology has the following defects: during detection, the water in the device is generally stored in the water storage structure. During detection, the water outlet part of the water storage structure is directly in contact with the asphalt pavement, and all the water in the water storage structure directly exerts pressure on the asphalt pavement. As the pavement permeates, the water volume in the water storage structure gradually decreases, which will cause the water pressure on the asphalt pavement to gradually change, and the permeability of the asphalt pavement cannot be stably detected. A device for detecting water seepage during asphalt construction on a road surface is proposed for this purpose. Summary of the invention

After the detection tube is controlled to contact with the asphalt pavement, water is added to the detection tube through the water storage barrel and the coaxial tube.

The threaded barrel engages with the rotating threaded rod to drive the flat plate to move up and down. The flat plate drives the coaxial tube to move up and down relative to the detection barrel. When the coaxial tube moves up and down, the water-passing rotating plate is driven to rotate through the lower curved pipe to control the highest water level in the detection barrel and adjust the water pressure on the asphalt pavement.

[0019] 3. The present invention provides components such as a blocking plate, an elastic telescopic rod and a material hole. When the control plate moves downward to push the material storage barrel and the detection barrel downward through the force-bearing plate, the lower end of the elastic telescopic rod first contacts the road surface. When the control plate continues to move downward, the elastic telescopic rod is gradually compressed under the resistance of the road surface, driving the lower end of the hinged plate to gradually approach the material storage barrel. The hinged plate pushes the blocking plate to move. When the detection barrel and the waterproof molding cavity ring contact the ground, the blocking plate drives the material hole to connect with the material passage pipe and the material storage barrel, ensuring that the sealing liquid is discharged to seal the detection part all around only after the road surface contacts the detection barrel and the waterproof molding cavity ring, thereby preventing the sealing liquid from leaking.

[0031] The embodiment of the present invention discloses a road pavement asphalt construction water seepage detection device. Figure 1-Figure 9 As shown, it includes a supporting base frame 1 and a water storage barrel 2, the water storage barrel 2 is installed on the upper end of the supporting base frame 1, and an observation structure 5 is slidably installed on the upper end of the water storage barrel 2, the observation structure 5 includes a buoyancy disc 51 and a water flow scale plate 52, the buoyancy disc 51 is fixedly sleeved on the lower end of the water flow scale plate 52, the upper end of the water flow scale plate 52 slides through the top wall of the water storage barrel 2, water can be added to the lower part of the buoyancy disc 51 inside the water storage barrel 2 through the upper end of the water flow scale plate 52, the buoyancy disc 51 synchronously drives the water flow scale plate 52 to move up and down according to the change of the water surface in the water storage barrel 2, and the movement of the water flow scale plate 52 can be observed to observe the water level.

[0032] A detection cylinder 3 is arranged on the inner side of the supporting base frame 1 and below the water barrel 2. A glass observation strip A13 is installed on the circumferential side of the water barrel 2, and a glass observation strip B14 is installed on the circumferential side of the detection cylinder 3. The inside of the water barrel 2 and the detection cylinder 3 can be observed through the glass observation strip A13 and the glass observation strip B14. A coaxial tube 4 is installed at the axis of the detection cylinder 3. A plurality of evenly distributed water outlets 6 are provided on the circumferential side of the lower end of the coaxial tube 4. A matching vertical plate 9 is slidably penetrated through the inner bottom wall of each water outlet 6. Water in the coaxial tube 4 can flow into the detection cylinder 3 through the water outlet 6.

[0033] A buoyancy structure 7 is provided at the lower side of the coaxial tube 4, and the lower end of the vertical plate 9 is fixed to the buoyancy structure 7. The buoyancy structure 7 includes a permeable plate 71 and a buoyancy inner cavity ring 72. The lower end of the coaxial tube 4 is located at the inner ring side of the buoyancy inner cavity ring 72, and the buoyancy inner cavity ring 72 is coaxially fixed to the permeable plate 71. The lower end of the vertical plate 9 is fixed to the permeable plate 71. One end of the vertical plate 9 located inside the water outlet 6 is in a convex strip structure to prevent the vertical plate 9 from being separated from the water outlet 6. After the buoyancy inner cavity ring 72 contacts the water surface, it can move up and down synchronously with the water surface. When the upper end of the vertical plate 9 is separated from the inner top wall of the water outlet 6, the water in the coaxial tube 4 can flow into the detection tube 3 through the water outlet 6. When the water level in the detection tube 3 is high enough, the buoyancy inner cavity ring 72 pushes the vertical plate 9 upward under the buoyancy of the water surface to block the water outlet 6, thereby limiting the water surface height in the detection tube 3 and subjecting the asphalt pavement to stable water pressure.

[0034] An extendable water-permeable structure 8 is installed at the upper end of the coaxial tube 4 , and the upper end of the extendable water-permeable structure 8 is connected and installed with the lower end of the water storage barrel 2 .

[0035] The extendable water-through structure 8 includes two water-through rotating plates 81, a lower curved pipe 82 and an upper curved pipe 83. The ends of the two water-through rotating plates 81 close to each other are rotatably connected and installed through the longitudinal water-through pipe 84, and the ends of the two water-through rotating plates 81 away from each other are respectively rotatably connected and installed with the upper curved pipe 83 and the lower curved pipe 82. The upper end of the upper curved pipe 83 is connected and installed with the bottom surface of the water storage bucket 2, and the lower end of the lower curved pipe 82 is connected and installed with the upper end of the coaxial pipe 4. The ends of the upper curved pipe 83 and the lower curved pipe 82 away from each other are both vertical ends, and the upper curved pipe 83 and the lower curved pipe 82 are close to each other. The near end is a horizontal end, and the upper end of the upper curved pipe 83 is connected to a hollow plate 85, and a water blocking plate 86 is slidably inserted inside the hollow plate 85. A power telescopic rod B87 is installed at the front end of the water blocking plate 86, and the other end of the power telescopic rod B87 is fixed to the hollow plate 85. The power telescopic rod B87 can control whether the water blocking plate 86 blocks the upper curved pipe 83 and the water storage bucket 2 by telescoping. When the coaxial tube 4 moves up and down, the upper curved pipe 83 can drive the two water-passing rotating plates 81 to rotate relative to the longitudinal water-passing pipe, the lower curved pipe 82 and the upper curved pipe 83.

[0036] A flat plate 19 is fixed to one end of the coaxial tube 4 located above the detection cylinder 3, an adjusting motor 20 is fixed to the circumferential side of the detection cylinder 3, a threaded rod 21 is fixed to the output end of the adjusting motor 20, a threaded cylinder 22 is threadedly sleeved on the threaded rod 21, the upper end of the threaded cylinder 22 is fixed to the bottom surface of the flat plate 19, and the threaded cylinder 22 can adjust the distance between the lower end of the coaxial tube 4 and the lower end of the detection cylinder 3 by engaging with the rotating threaded rod 21, thereby controlling the highest water level in the detection cylinder 3.

[0037] A control panel 10 is arranged between the water storage barrel 2 and the detection tube 3. Side panels 11 are slidably connected to the front and rear sides of the detection tube 3. The upper ends of the side panels 11 are fixed to the supporting base frame 1. The side panels 11 are slidably sleeved on the outer surface of the control panel 10. The bottom surface of the control panel 10 is elastically connected to the detection tube 3. Power telescopic rods A12 are installed on both sides of the supporting base frame 1, and the lower ends of the power telescopic rods A12 are connected to the control panel 10.

[0038] A waterproof molded cavity ring 15 is installed on the circumferential side of the lower end of the detection cylinder 3, and the lower end of the waterproof molded cavity ring 15 is flush with the bottom surface of the detection cylinder 3. A spray ring 16 is installed on the inner top wall of the waterproof molded cavity ring 15. The upper end of the spray ring 16 is connected to a material passing pipe 17, and the upper end of the material passing pipe 17 slides through the inner top wall of the waterproof molded cavity ring 15. A material storage structure 18 is installed on the circumferential side of the detection cylinder 3, and the lower end of the material storage structure 18 is connected to the upper end of the material passing pipe 17.

[0039] The material storage structure 18 includes a material storage barrel 181 and a pressure plate 182. The material storage barrel 181 is fixed to the circumferential side of the detection tube 3. The pressure plate 182 is slidably inserted at the lower end of the material storage barrel 181. The lower end of the material storage barrel 181 is connected and installed with the upper end of the material passage pipe 17. A feeding pipe 183 is installed through the bottom surface of the pressure plate 182. The upper end of the feeding pipe 183 slides through the top wall of the material storage barrel 181. The bottom surface of the material storage barrel 181 is provided with a movable groove 186 connected to the inside. The movable groove 186 is provided with a movable groove 186. A blocking plate 187 is slidably inserted in the bottom of the blocking plate 187, and a through block 188 is fixed on the bottom surface of the blocking plate 187 and on both sides of the through pipe 17. The lower end of the through block 188 slides through the bottom surface of the movable groove 186. A material hole 189 is opened on the upper surface of the blocking plate 187. A hole structure coaxial with the through pipe 17 is opened at the connection between the top wall of the movable groove 186 and the storage barrel 181. An elastic telescopic rod 1810 is arranged below the storage barrel 181. The telescopic end of the elastic telescopic rod 1810 is connected to the through pipe 17. The bottom surface of the material storage barrel 181 is fixed, and the fixed end of the elastic telescopic rod 1810 is rotatably connected to two hinged plates 1811. The upper ends of the two hinged plates 1811 are rotatably connected to the lower ends of the two penetration blocks 188 respectively. The lower end of the elastic telescopic rod 1810 is located below the lower end of the detection cylinder 3. When the detection cylinder 3 moves downward, when the control board 10 pushes the material storage barrel 181 and the detection cylinder 3 downward, the lower end of the elastic telescopic rod 1810 first contacts the road surface. When the control board 10 continues to move downward, the elastic telescopic rod 1810 is gradually compressed under the resistance of the road surface, driving the lower end of the hinged plate 1811 to gradually approach the material storage barrel 181. The hinged plate 1811 pushes the blocking plate 187 to move. When the detection cylinder 3 and the waterproof molding cavity ring 15 are in contact with the ground, the blocking plate 187 drives the material hole 189 to communicate with the material pipe 17 and the material storage barrel 181, ensuring that only after the road surface contacts the detection cylinder 3 and the waterproof molding cavity ring 15, the sealing liquid will be discharged to seal the surrounding areas of the detection part.

[0040] The upper end of the feeding tube 183 is elastically connected to the upper surface of the storage barrel 181, and a sealing rod 185 is inserted into the internal thread of the feeding tube 183. The sealing rod 185 is rotated to separate it from the feeding tube 183, and sealed liquid raw materials can be added to the storage barrel 181 through the feeding tube 183. Two force plates 184 are installed circumferentially on the upper end of the feeding tube 183. The force plates 184 are located below the control panel 10. The left end of the control panel 10 is U-shaped and recessed. The feeding tube 183 is located inside the U-shaped groove of the control panel 10. When the control panel 10 moves downward, the U-shaped recessed structure pushes the force plate 184 downward.

[0041] The working principle is as follows: the power telescopic rod A12 pushes the control board 10 downward by extending, and the control board 10 pushes the detection tube 3 to contact the asphalt pavement through the elastic connection, and then water is added to the water storage barrel 2. The water in the water storage barrel 2 is filled into the coaxial tube 4 through the upper curved pipe 83, the water-passing rotating plate 81 and the lower curved pipe 82. The water in the coaxial tube 4 is added to the detection tube 3 through the water outlet 6. When the water contacts the buoyancy structure 7, the buoyancy structure 7 gradually pushes the vertical plate 9 to move upward by the buoyancy of the water. When the vertical plate 9 completely blocks the water outlet 6, the water in the coaxial tube 4 stops adding water to the detection tube 3, and the highest position of the water in the detection tube 3 is limited. When the water level in the detection tube 3 is lowered due to the infiltration of the road surface, the buoyancy structure 7 moves downward with the water level, so that the water in the coaxial tube 4 can be added to the detection tube 3 through the water outlet 6 again, so that the water level in the detection tube 3 is stably maintained at a certain height, so that the pressure of water on the asphalt pavement is kept stable, and the stability of the detection is improved.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
