Abstract
Description
Technical Field
[0001] This invention belongs to the field of highway maintenance technology, and in particular relates to a rapid detection and repair device and method for road potholes. Background Technology
[0002] Potholes and other localized damage are typical road surface defects. Potholes significantly impact road surface smoothness, driving comfort, and safety, especially given the increasingly prevalent overloading in my country's traffic, which exacerbates the likelihood of pothole damage. Therefore, timely detection and repair of road surface potholes is crucial. However, current technologies often lack standardized methods for pothole detection and repair, resulting in significant randomness. Furthermore, most repairs rely on manual filling, leading to low efficiency, reduced traffic flow, and inconsistent standards. Therefore, this paper proposes a rapid detection and repair device and method for road potholes.
[0003] The rapid pothole detection and repair device is a tool used for the rapid detection and repair of potholes on highway surfaces. Currently, there are often no unified standards for the detection and repair of potholes. Determining whether a pothole needs repair often relies on manual experience, resulting in some potholes that need repair often going unrepaired. Furthermore, repairs are largely done manually, which is inefficient and leads to prolonged lane closures, reducing highway traffic flow. Therefore, this rapid pothole detection and repair device and method are proposed to quickly complete the detection and repair of potholes.
[0004] In view of this, the present invention discloses a rapid detection and repair device and method for road potholes, which improves the efficiency of detection and repair of highway potholes, has wide applicability, can be used for both national and provincial highways, has a high degree of automation, and can improve the efficiency of highway pothole maintenance. Summary of the Invention
[0005] The purpose of this invention is to address the current lack of relevant equipment and methods for the detection and maintenance of road potholes by providing a rapid detection and repair device and method for road potholes. The device has a reasonable structural design, is fast and efficient, and the method is simple to operate and energy-saving and environmentally friendly.
[0006] The aforementioned rapid detection and repair device for road potholes includes a frame, horizontal shovel, adhesive, rubber rod, biodegradable plastic sheet, roller, scraper, flushing pipe, water tank, disposable plastic bag, soft thin pipe, small annular iron sheet, electromagnet, air extractor, telescopic cylinder system, grouting pipe, mixing box, flexible adhesive, vertical round bar, movable patch adhesive, displacement sensor, movable patch, and valve.
[0007] Furthermore, the biodegradable plastic board is black in color, matching the road surface color, and has rubber rods evenly distributed at the bottom, which can compact the mixed filler and reinforce the filler body. Its lower ends have adhesive, which can firmly fix it to the road surface. It will automatically degrade after half a month and become integrated with the road surface.
[0008] Furthermore, the telescopic cylinder system consists of a total of 64 telescopic cylinders arranged in an 8*8 configuration, with a spacing of 5cm. The vertical cylindrical bar in the middle of each telescopic cylinder can extend and retract freely. The vertical cylindrical bar is centered and flexibly fixed at the bottom by a flexible adhesive. There is a displacement sensor at the top, which calculates the vertical deformation of each cylinder. There is a movable patch at the top. When vertical deformation occurs, one end of the patch moves downward, and a crack appears at the top, which can realize the grouting function.
[0009] Furthermore, the disposable plastic bag comes with a soft, thin tube that connects to a vacuum pump. By drawing a vacuum, it achieves close contact with the surface of the groove. One end of the soft, thin tube is thicker, while the end connected to the vacuum pump is softer. It is funnel-shaped with a small annular iron piece at the opening of the funnel. The vacuum pump opening is equipped with an electromagnet, which can be used to perform vacuuming, adsorption, and disconnection operations via a battery and a switch.
[0010] Furthermore, the rollers are equipped with scrapers, which can compact the mixture. The scrapers and water spraying device can clean the substances adhering to the rollers. The horizontal bucket can recycle waste and avoid polluting the road surface environment.
[0011] The operating method of the above-mentioned rapid detection and repair device for road potholes is as follows: During inspection and repair, a trailer tows the entire device at a low speed along the section of road to be inspected. The telescopic boom system detects potholes. When more than 32 telescopic booms deform vertically by more than 6 cm, an alarm is triggered, confirming the pothole requires repair. The trailer is moved forward until a disposable plastic bag is aligned with the pothole. The bag is lowered, and an electromagnet is energized. The electromagnet attracts a small annular iron plate, completing the closure. A vacuum is then created to ensure tight contact between the plastic bag and the pothole. After completion, the power is cut off, disconnecting the plastic bag's conduit from the vacuum pump. Simultaneously, the mixing tank valve is opened. The vertical rod in the center of the telescopic boom automatically moves downwards upon encountering the pothole, while the free end of the movable patch rotates, creating a crack at the top that gradually widens. Grout enters the telescopic boom until it reaches the pothole, enabling grouting. As the grout fills, the vertical rod in the center of the telescopic boom rises, closing the patch and completing the grouting process. The grouting process involves moving the device forward to compact the grout with rollers. Then, the device continues to move forward to cover the repair area with a biodegradable plastic sheet. This sheet adheres closely to the road surface, is black, and does not impede traffic. It degrades automatically over time. Finally, a horizontal shovel cleans up any spilled grout, completing the rapid pothole detection and repair process. This method automatically detects potholes requiring repair and achieves rapid, environmentally friendly repair. It fills a gap in rapid pothole repair for highways in China. The device and method are highly efficient and accurate, requiring minimal manpower, and have significant implications for on-site monitoring and maintenance.
[0012] The advantages and technical effects of this invention are as follows: 1. The biodegradable plastic board has rubber rods evenly distributed at the bottom, which can compact the mixed filler and reinforce the filler body. The bottom two ends are self-adhesive, which can be firmly fixed to the road surface. 2. In the telescopic cylinder system, the vertical cylindrical bar in the middle of each telescopic cylinder can extend and retract freely, and there is a movable patch at the top. After vertical deformation occurs, one end of the patch moves downward, and a crack appears at the top, which can realize the grouting function.
[0013] 3. The disposable plastic bag comes with a soft, thin tube that connects to a vacuum pump. It achieves close contact with the surface of the groove by drawing a vacuum. One end of the soft, thin tube is thicker, while the end connected to the vacuum pump is softer. It is funnel-shaped with a small annular iron piece at the opening of the funnel. The vacuum pump opening is equipped with an electromagnet, and the vacuuming and disconnection operations can be achieved through a battery and a switch. Attached Figure Description
