Description
Technical Field
[0001] This utility model relates to the field of detection device technology, and in particular to an asphalt pavement water seepage detection device. Background Technology
[0002] Asphalt pavement permeability testing is a crucial quality control and performance evaluation indicator, directly impacting pavement durability and serviceability. An excessively high permeability coefficient typically indicates insufficient pavement compaction and excessive porosity, leading to insufficient asphalt mixture strength and susceptibility to rutting and loosening. Currently, asphalt pavement permeability testing using equipment involves applying a ring of sealant to the pavement, ensuring it fills all gaps and adheres firmly before fixing the testing device. However, due to the presence of dust and debris on the ground, manual cleaning is required before applying the sealant. This process is cumbersome, and manual application makes it difficult to control the amount of sealant applied. Applying too much leads to waste, while applying too little may not achieve the desired sealing effect. Furthermore, uneven application of the sealant can result in gaps even after the testing device is placed on top, causing water leakage. Utility Model Content
[0003] This utility model discloses an asphalt pavement water seepage detection device, which solves the problem of manual application of sealant material, which requires cleaning the road surface first, is cumbersome, and makes it difficult to control the amount of sealant material applied. As a result, even after the detection device is placed on the sealant material, gaps still exist, causing water leakage.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An asphalt pavement water seepage detection device includes a trolley, a connecting plate fixed on the trolley, a lifting plate on the connecting plate, a sealing cylinder that moves synchronously with the lifting plate below the lifting plate, an opening on the trolley for the sealing cylinder to pass through, an annular cavity for filling waterproof sealant on the bottom surface of the sealing cylinder, a liftable push plate inside the cavity, a first electric telescopic rod for driving the push plate on the lifting plate, a perforated disc inside the sealing cylinder, a second electric telescopic rod for driving the disc to rise and fall on the sealing cylinder, a fan on the lifting plate for blowing air into the disc, a measuring cylinder for injecting water into the sealing cylinder fixed on the lifting plate, and a third electric telescopic rod for driving the lifting plate to rise and fall fixed on the connecting plate.
[0005] Compared with the prior art, the present invention has the following beneficial effects: After moving the trolley to the designated position, align the sealing cylinder with the area of the road surface to be inspected. Then, activate the third electric telescopic rod to drive the lifting plate, causing the sealing cylinder to move downwards synchronously. The sealing cylinder passes through the opening on the trolley. When the sealing cylinder approaches the road surface, the third electric telescopic rod closes, and the second electric telescopic rod activates, causing the disc to move downwards and contact the road surface. Then, the fan blows air into the disc, which is then expelled through perforations, removing dust and other impurities from the area being inspected, thus cleaning the inspected area. The second electric telescopic rod then drives the disc back to its original position, and subsequently, the third electric telescopic rod continues to drive the sealing cylinder downwards until its bottom contacts the road surface, covering the area to be inspected. The first electric telescopic rod is activated, driving the push plate to move downwards. The push plate then pushes the waterproof sealant filling the cavity downwards, allowing the sealant to adhere to the road surface and fill the gaps, improving the sealing effect of the sealing cylinder. Water is then injected into the measuring cylinder, entering the sealing cylinder. The changes in the water level inside the measuring cylinder are then observed and recorded, completing the water seepage detection of the asphalt pavement. This invention can quickly clean dust and impurities from the road surface before conducting water seepage detection on asphalt pavement. Subsequently, the waterproof sealant can be automatically squeezed onto the road surface to fill all the gaps, further preventing water leakage from the gap between the sealing cylinder and the road surface. The operation process is simple and fast. Attached Figure Description

[0009] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0010] like Figure 1 and Figure 2As shown, this utility model provides an asphalt pavement water seepage detection device, including a trolley 1, a connecting plate 2 fixed on the trolley 1, a lifting plate 21 on the connecting plate 2, a sealing cylinder 3 below the lifting plate 21 that moves synchronously with the lifting plate 21, an opening on the trolley 1 for the sealing cylinder 3 to pass through, a ring-shaped placement cavity 31 on the bottom surface of the sealing cylinder 3 for filling with waterproof sealant 35, a liftable push plate 32 inside the placement cavity 31, a first electric telescopic rod 33 on the lifting plate 21 for driving the push plate 32; a disc 4 with a perforated outer surface inside the sealing cylinder 3, a second electric telescopic rod 41 on the sealing cylinder 3 for driving the disc 4 to rise and fall, a fan 22 on the lifting plate 21 for blowing air into the disc 4; a measuring cylinder 5 for injecting water into the sealing cylinder 3 fixed on the lifting plate 21, and a third electric telescopic rod 6 fixed on the connecting plate 2 for driving the lifting plate 21 to rise and fall. A water tank 7 is fixed on the trolley 1, and a first water pump 71 is fixed on the water tank 7. The drain end of the first water pump 71 is connected to a first flexible hose 72, and the drain end of the first flexible hose 72 is connected to the top of the measuring cylinder 5. The bottom of the measuring cylinder 5 is connected to a water supply pipe 51 connected to the top of the sealing cylinder 3, and a valve 52 is installed on the water supply pipe 51. The telescopic end of the third electric telescopic rod 6 is fixed with a vertical pipe 24 that passes through the lifting plate 21. The bottom of the vertical pipe 24 is connected to a folding pipe 25. The top of the disc 4 is connected to a connecting pipe 42 that passes through the top of the sealing cylinder 3 and is connected to the folding pipe 25. The exhaust end of the fan 22 is connected to a horizontal pipe 23 that is connected to the vertical pipe 24. The telescopic end of the first electric telescopic rod 33 is fixed with a vertical rod 34. The bottom end of the vertical rod 34 is located in the placement cavity 31 and connected to the push plate 32. A fixing ring 36 for the disc 4 to enter is fixed at the top of the sealing cylinder 3. After moving the trolley 1 to the designated position, align the sealing cylinder 3 with the part of the asphalt pavement that needs to be inspected. The connecting plate 2 is L-shaped. The fixed end of the third electric telescopic rod 6 passes through the top of the connecting plate 2. The lifting plate 21 is slidably connected to the vertical surface inside the connecting plate 2. After the telescopic end of the third electric telescopic rod 6 drives the lifting plate 21 to move downward through the vertical pipe 24, the lifting plate 21 drives the sealing cylinder 3 to move downward through the water supply pipe 51, so that the sealing cylinder 3 passes through the opening on the trolley 1. The fixed end of the second electric telescopic rod 41 passes through the top of the sealing cylinder 3, and the telescopic end is fixed to the top of the disc 4. When the sealing cylinder 3 approaches the road surface, the third electric telescopic rod 6 closes, and the second electric telescopic rod 41 starts and drives the disc 4 to move downward, so that the connecting pipe 42 stretches the folded pipe 25. The disc 4 then contacts the road surface. The air blown out by the fan 22 enters the vertical pipe 24 through the horizontal pipe 23, and then continues to enter the connecting pipe 42 through the folded pipe 25. Finally, it enters the disc 4 and is discharged through the perforations. The air can blow away dust and other impurities on the road surface inspection area, and quickly clean the area of the road surface that needs to be inspected. In addition, the perforations on the disc 4 are distributed in a ring array to avoid cleaning dead corners.After the dust on the road surface inspection area is cleaned, the telescopic end of the second electric telescopic rod 41 drives the disc 4 to move upward, so that the disc 4 enters the inner side of the fixing ring 36. The inner wall of the fixing ring 36 contacts the outer wall of the disc 4, sealing the perforations on the disc 4. Then, the third electric telescopic rod 6 continues to move downward, so that the bottom of the sealing cylinder 3 contacts the road surface. Then, the first electric telescopic rod 33 (the fixed end of the first electric telescopic rod 33 is fixed to the bottom of the lifting plate 21) is activated, so that the vertical rod 34 pushes the waterproof sealing putty 35 filled in the placement cavity 31 downward through the push plate 32 (the push plate 32 is arranged in a ring), so that the waterproof sealing putty 35 adheres to the road surface and fills the gaps in the road surface, further preventing water in the sealing cylinder 3 from leaking out through the gap between the road surface and the bottom surface of the sealing cylinder 3. Then, the first water pump 71 is activated to deliver water to the measuring cylinder 5 through the first hose 72. The valve 52 on the water supply pipe 51 is opened to allow water to enter the sealing cylinder 3. The top of the device has a vent hole, into which a sealing plug is inserted (the vent hole and sealing plug are not shown in the figure). The sealing plug can be removed to observe whether water flows out through the vent hole, thus determining whether the sealed cylinder 3 is full of water. Once full, the sealing plug is inserted back into the vent hole. The changes in the water level in the measuring cylinder 5 are then observed and recorded to complete the water seepage detection of the asphalt pavement. The trolley 1 is equipped with a battery and a control panel (not shown in the figure). The battery supplies power to the first electric telescopic pole 33, the second electric telescopic pole 41, the third electric telescopic pole 6, the first water pump 71, and the fan 22. The control panel allows for the installation of a control program to start and stop the first electric telescopic pole 33, the second electric telescopic pole 41, the third electric telescopic pole 6, the first water pump 71, and the fan 22. There are two first electric telescopic poles 33, which are raised and lowered synchronously via a control program. The method of controlling the two first electric telescopic poles 33 is existing technology and will not be elaborated here.
[0011] like Figure 1 , Figure 2 and Figure 3As shown, a second water pump 8 is fixed on the lifting plate 21. The pumping end of the second water pump 8 is connected to a pumping pipe 81 that penetrates the top of the sealing cylinder 3. The draining end of the second water pump 8 is connected to a second flexible hose 82 for draining water into the water tank 7. The draining end of the second flexible hose 82 is connected to a connecting cylinder 83 placed on top of the water tank 7. The bottom of the connecting cylinder 83 is open, and a collecting cylinder 9 is threaded inside the connecting cylinder 83. The bottom of the collecting cylinder 9 is connected to a drain pipe 91. The top of the water tank 7 has a hole for inserting the drain pipe 91. A bearing ring 92 is fixed inside the collecting cylinder 9, and a filter screen 93 is fixed on the bearing ring 92. A rubber ring 37 is fixed to the bottom of the sealing cylinder 3. The battery can power the second water pump 8, and the control panel can also control the operation of the second water pump 8. After the road seepage detection is completed, the device on the water supply pipe 51 is turned off, and the second water pump 8 starts. Water is drawn out of the sealed cylinder 3 through the water suction pipe 81, and then discharged into the connecting cylinder 83 through the second hose 82. The water enters the collecting cylinder 9, is filtered by the filter screen 93, and then enters the water tank 7 through the drain pipe 91 for water recycling. Subsequently, the connecting cylinder 83 can be removed from the top of the water tank 7, allowing the drain pipe 91 to be moved out of the hole. Then, the collecting cylinder 9 is rotated to separate the collecting cylinder 9 from the connecting cylinder 83, so that the impurities filtered on the filter screen 93 can be cleaned. When the sealed cylinder 3 moves downward, the rubber ring 37 (there are two rubber rings 37, such as...) Figure 2 The bottom of the sealing cylinder 3 (as shown in the image) is in contact with the road surface, which further improves the sealing effect after the bottom surface of the sealing cylinder 3 is pressed onto the road surface, and can prevent gaps from appearing after the bottom surface of the sealing cylinder 3 rubs against the road surface for a long time.
