Description

Technical Field

[0001] The invention relates to the technical field of highway quality detection, and in particular to a highway pavement construction quality detection method. Background Art

[0002] Roads are infrastructure for various trackless vehicles and pedestrians to pass through. After the road construction is completed, it is generally necessary to inspect the construction quality of the road. The items usually inspected include the paving thickness of the road, the permeability of the asphalt road, the flatness and compaction of the road, etc. However, there are still certain problems in the use of the current highway pavement construction quality inspection device, and patent documents have been used to improve this.

[0003] For example, Chinese patent CN116067863B discloses a road pavement construction quality inspection device, including a vehicle body, a roller mounted on the lower end of the vehicle body, a push rod fixedly connected to the upper right end of the vehicle body, a water tank mounted on the upper middle end of the vehicle body, support columns fixed on both sides of the right end of the vehicle body, and a support frame connected to the left side of the support column, a movable plate passing through the upper end of the support column, a mounting plate bolted to the left side of the movable plate, a dual-axis motor fixed to the upper end of the mounting plate, and a second threaded screw rod passing through the upper end of the support frame. The road pavement construction quality inspection device, by setting a wastewater recovery mechanism, can recycle wastewater generated by cooling and dust reduction during drilling and coring, without causing pollution to the road surface and moisture generated by cleaning, without manual cleaning, reducing the workload of operators, and the cooling liquid delivered by the cooling mechanism can directly reach the bottom of the drill bit, with better cooling effect, less use of cooling liquid, and reduced waste of water resources.

[0004] Although the equipment in the above document can detect water seepage on the road surface and drill holes to take samples, it still has defects that need to be improved in actual use, such as: When a highway is being built, the top surface is usually repaired more thoroughly, which improves its waterproofness. Therefore, when the equipment is testing the highway surface, it usually does not show serious water seepage data. However, the interior of the highway cannot be effectively tested by the equipment, which makes the test incomplete. Once the surface of the highway is damaged, rainwater will directly penetrate into the interior of the entire highway and cause damage to it. Therefore, a highway pavement construction quality inspection method that can improve inspection accuracy is now designed to solve such defects. Summary of the invention

Beneficial Effects

[0016] The present invention provides a method for detecting the quality of highway pavement construction. Compared with the existing technology, it has the following beneficial effects: (1) The highway pavement construction quality inspection method combines the water injection moving mechanism and the sampling inspection mechanism. The two mechanisms can be used to drill holes in the highway and take samples in turn, clean the holes, and finally use the holes to conduct a more comprehensive water seepage inspection on the inside of the highway to ensure the accuracy of the data. At the same time, the linkage between the structures can be used to allow the round gear column to cooperate with the motor to disassemble and remove the sample, effectively improving the overall practical functionality of the equipment.

[0017] (2) This highway pavement construction quality inspection method uses a cross slide table to install a third rectangular seat inside the load-bearing slide frame, and installs a motor on the top of the third rectangular seat, and is used in conjunction with a tapping rod and a cutting cylinder. The arrangement of these structures enables the tapping rod to drill and tap on the top of the sample when the cutting cylinder cuts and samples, so that the tapping rod and the sample are engaged, so that the sample can be directly pulled out of the hole after the third rectangular seat is pulled up, and the staff need to use tools to clamp the sample later, which is convenient for use.

[0018] (3) The highway pavement construction quality inspection method comprises a sealing cylinder disposed below the first rectangular seat, and an air guide tube, a hollow disk and an air bag ring disposed inside the sealing cylinder, which are used in conjunction with a compression plug. After the hollow disk enters the hole, the compression plug can compress the air inside the air guide tube to expand the air bag ring and block the hole, thereby improving the sealing of the hole and facilitating the subsequent water injection into the hole to inspect the water permeability inside the highway, thereby ensuring the accuracy of the inspection data and the stability during operation.

[0019] (4) This highway pavement construction quality inspection method uses a first tooth frame to install a lifting plate and a round tooth column on the left side of the inner cavity of the equipment box, and uses it in conjunction with a rectangular sleeve and a horizontal insertion rod. The arrangement of these structures can use the round tooth column to limit the bottom of the sample when the sealing cylinder is performing penetration testing, so that the tapping rod can rotate in the opposite direction and disengage from the sample, and push the sample down and disengage from the cutting cylinder, making it convenient for the staff to take out the sample.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-13 The present invention provides a technical solution: a method for detecting the quality of highway pavement construction, which specifically comprises the following steps: S1. Equipment movement: Before use, the water injection mobile mechanism 1 is pushed as a whole to a designated position on the highway using tires on both sides for preparation; S2, road surface sampling: start the cylinder 102 to push the cutting cylinder 218 in the sampling and detection mechanism 2 down to drill holes in the road surface for sampling; S3, hole cleaning: move the second rectangular seat 205, and lower the water spray rack 220 into the hole to clean the inner wall of the hole; S4, penetration test: move the sealing cylinder 207, and make the airbag ring 212 and the sealing cylinder 207 descend to dock with the hole, and then inject water for testing; S5. Sample disassembly: While testing, the round tooth column 115 is driven to dock with the sample, and the sample is disassembled and taken out.

[0024] The above-mentioned method for detecting the quality of highway pavement construction comprises the following more specific steps: S1. Equipment movement: Before use, first use the tires on both sides to push the water injection mobile mechanism 1 as a whole to the designated position on the road, and align the cutting barrel 218 with the sampling point, and the preparation process is completed at this time; S2, road surface sampling: start cylinder 102 to push cutting cylinder 218 in sampling detection mechanism 2 to descend. As docking plate 103 and concave frame 221 are docked, third rectangular seat 206 and U-shaped groove 203 will be separated. At the same time, upper push rod 127 no longer presses rectangular rod 104, so that positioning vertical plate 106 rises under the elastic force of spring 107 and inserts into concave frame 221 and inner side of positioning groove 105 to lock docking plate 103 and concave frame 221. During the descent, motor 216 starts to drive tapping rod 217 and cutting cylinder 218 to rotate synchronously. When descending to the road surface, cutting cylinder 218 performs cylindrical cutting on the road surface. After the distance, the tapping rod 217 will open a hole on the top of the sample and perform tapping to engage the tapping rod 217 with the sample until the cutting cylinder 218 completely cuts the sample and separates it from the road, then the motor 216 is turned off, and then the cylinder 102 drives the third rectangular seat 206 to rise. Since the tapping rod 217 engages with the inner side of the sample, the cutting cylinder 218 also drives the sample up. When the third rectangular seat 206 rises to the inner side of the U-shaped groove 203 again, the upper push rod 127 will also press the rectangular rod 104 to allow the positioning vertical plate 106 to withdraw from the positioning groove 105 and the inner side of the concave frame 221, and unlock the concave frame 221 and the docking plate 103; S3, hole cleaning: after the sealing cylinder 207 is raised, pull the U-shaped rod 224 out from the inner side of the calibration groove 126 by hand, then pull the support rod 222 to drive the horizontal slide 202 to move left on the inner side of the load-bearing slide frame 201 until the U-shaped rod 224 is inserted into the calibration groove 126 in the middle and stops. At this time, the concave frame 221 at the rear of the second rectangular seat 205 is accurately docked with the docking plate 103, and then the cylinder 102 is started again to push the second rectangular seat 205 down to make the water spray rack 220 enter the hole. At this time, the water pump 121 is started, and the solenoid valve 124 opens the water pipe 122 connected to the docking pipe 219. The water pump 121 draws water from the water tank 120 and sprays it through the water spray rack 220 to wash away the dust on the inner wall of the hole. After the washing is completed, the cylinder 102 pulls the second rectangular seat 205 up again and resets it to the U-shaped groove 203; S4, penetration test: after the third rectangular seat 206 rises, move the horizontal slide 202 to make the concave frame 221 at the rear of the first rectangular seat 204 dock with the docking plate 103, and at the same time, the horizontal insertion rod 214 is also inserted into the inner side of the rectangular sleeve 119, and then the cylinder 102 pushes the first rectangular seat 204 to descend, and the hollow disk 211 first enters the hole, and after the hollow disk 211 touches the bottom, the first rectangular seat 204 will push the sealing tube 207 to slide on the surface of the air guide tube 208 and continue to descend to compress the third spring 209. At this time, the compression plug 213 follows the first rectangular seat 204 to descend and insert into the air guide tube 208 to squeeze and compress, so that the air inside the air guide tube 208 is compressed into the inside of the hollow disk 211 and the air bag ring 212 is bulged to fully fill the inner wall of the hole. Fill and fit, at this time the hole is sealed, and when the sealing ring 210 fits with the road surface to surround the hole, the cylinder 102 stops descending, and at this time the solenoid valve 124 opens the water pipe 122 connected to the extension pipe 215, so that water is injected into the sealing cylinder 207 through the extension pipe 215 and fills the hole, and then it is left to stand to observe whether the water level inside the sealing cylinder 207 drops, so as to observe the water permeability of the road, and after the detection is completed, the cylinder 102 is started to pull the first rectangular seat 204 up, and when the first rectangular seat 204 drives the sealing cylinder 207 to rise and separate from the road surface, the compressed third spring 209 pushes the air pipe 208 and the hollow disk 211 to descend, so that the air pipe 208 is separated from the compression plug 213 and reset to release the air inside the air pipe 208; S5. Sample removal: During the process of step S4, the first rectangular seat 204 will drive the U-shaped plate 117 and the second tooth frame 110 to descend while descending. The descent of the second tooth frame 110 will cause the first tooth frame 109 to drive the guide rod frame 112 and the lifting plate 113 to rise through the rotation of the gear cylinder 111, so that the round tooth column 115 enters the interior of the cutting cylinder 218 and uses the elastic force of the first spring 114 to press only the bottom of the sample. At the same time, the motor 216 starts to drive the tapping rod 217 to rotate in the opposite direction. When the tapping rod 217 rotates in the opposite direction, it will push the sample down and separate the tapping rod 217 from it. After the sample is pushed down by the tapping rod 217, it will also press the lifting plate 113 to sink under the guidance of the guide rod frame 112, so that the sample is completely separated from the interior of the cutting cylinder 218, and then the sample is taken out.
