Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road maintenance engineering. More specifically, it relates to an anti-aging road surface structure for road maintenance engineering. Background Art
[0002] In the field of modern road engineering, the anti-aging road surface structure for road maintenance engineering has always been an important topic that has received much attention. However, the existing technologies still face many challenges and deficiencies when dealing with road surface aging problems.
[0003] First of all, whether it is a cement road surface or an asphalt road surface, various forms of damage, deformation and other defects will inevitably occur within a certain period after being put into use. One of the main reasons for road aging is the pumping phenomenon that occurs under the dual influence of vehicle load and rainwater infiltration. Pumping will cause the road surface to crack, which will in turn lead to more serious road surface damage. The existing road surface layers generally have the problem of strong water permeability, which allows rainwater to easily penetrate into the concrete layer below the road surface layer. The long-term erosion of water will not only weaken the strength of the roadbed, but also accelerate the aging process of the entire road surface structure. In this case, the service life of the road is greatly shortened, and the maintenance frequency increases, which not only increases the maintenance cost, but also affects the normal operation of traffic.
[0004] Secondly, under high-temperature weather conditions, especially for asphalt road surfaces, more severe challenges are faced. Strong direct sunlight will cause the road surface temperature to rise rapidly. In this case, the bonding property of the asphalt material decreases and it becomes softer. When heavy vehicles drive on the high-temperature road surface, it is easy to cause flowing ruts. These ruts not only damage the flatness of the road surface, but more seriously, they will cause the overall damage of the road surface structure and accelerate the aging degree of the asphalt road surface. The road surface deformation caused by high temperature not only affects the driving comfort and safety, but also causes water accumulation on rainy days, further exacerbating the damage of the road surface.
[0005] In addition, in the daily road surface maintenance work, there are also obvious deficiencies in the existing technologies for spraying maintenance materials. At present, most maintenance work still relies on manually adjusting the height of the spraying device to control the spraying range of the nozzle. This method has multiple problems: First of all, no matter how it is adjusted, it is difficult to achieve full coverage of the road surface, and there will always be some areas that cannot be fully maintained. Secondly, the manual adjustment process is cumbersome, time-consuming and laborious, and the efficiency is low. Summary of the Utility Model

[0017] (III) Beneficial effects
[0018] Compared with the prior art, the present utility model provides an anti-aging road surface structure for road maintenance projects, having the following beneficial effects:
[0019] 1. Through the multi-layer structure design, the protection device effectively solves the problem in the prior art that the road surface layer has strong water permeability, resulting in road surface aging. The ingenious combination of the mixing layer, concrete layer, water isolation layer, cushion layer, anti-seepage layer, top layer of the roadbed, and bottom layer of the roadbed not only enhances the overall strength of the road surface structure but also significantly improves the waterproof performance. In particular, the provision of the water isolation layer and the anti-seepage layer effectively prevents rainwater from seeping downward and groundwater from seeping upward, fundamentally solving the problems of pumping slurry and weakening of the roadbed strength. The design of the pipeline and the connecting pipe in the cushion layer, in cooperation with the communicating chamber, connecting pipe, and water inlet pipe, forms an efficient drainage system that can quickly drain the infiltrated rainwater, preventing moisture from staying in the road surface structure for a long time. The provision of the filter holes further improves the drainage efficiency and at the same time prevents impurities from entering the drainage system. This design of multi-layer protection and efficient drainage greatly extends the service life of the road, reduces the maintenance frequency, lowers the maintenance cost, and at the same time ensures the normal operation of traffic.
[0020] 2. The innovative design of the cooling device effectively solves the problem that the asphalt road surface is prone to deformation in high-temperature weather. The combination of the main pipe, shunt pipe, spray head, delivery pipe, delivery pump, and water storage tank forms an efficient cooling system. This design can not only timely lower the road surface temperature, prevent asphalt softening and flowing rut caused by high temperature, but also delay road surface aging by regularly spraying maintenance materials. The open design at the top end of the water storage tank and the detachable filter plate facilitate the addition and filtration of water resources, improving the practicability and maintenance convenience of the system.
[0021] 3. The design of the lifting device ingeniously solves the problems of limited spraying range and inconvenient adjustment in the prior art. The coordinated work of the support rod, fixed plate, motor, transmission belt, transmission wheel, turntable, connecting rod, movable frame, movable groove and movable rod realizes the automatic reciprocating movement of the nozzle up and down. This design not only greatly expands the spraying coverage range, ensures comprehensive and uniform cooling and maintenance of the road surface, but also eliminates the cumbersome operation of manual adjustment, improves work efficiency. The automated design driven by the motor enables the system to quickly respond to changes in road surface conditions, timely adjust the spraying height and range, realizes precise control and timely maintenance. The delivery pipe made of hose material increases the flexibility of the system, facilitating adjustment and maintenance. This optimized structure not only improves the quality and efficiency of maintenance, but also realizes the rational utilization of maintenance resources, avoiding problems of overuse or insufficient coverage.

The water storage tank 7 is installed on the road surface 1, and lifting devices are arranged on both sides of the water storage tank 7.

The motor 10 is detachably installed on both sides of the water storage tank 7. The transmission belt 11 is sleeved outside the transmission wheel 12. The transmission wheel 12 is connected to one side of the turntable 13. The turntable 13 is rotatably installed on one side of the fixing plate 9. The connecting rod 14 is fixedly connected to one side of the fixing plate 9. The movable frame 15 is connected to one end of the connecting rod 14.

The movable rod 17 is movably arranged in the movable groove 16, and the movable rod 17 is fixedly connected to one side of the movable plate. A protection device is arranged below the road surface 1.
[0033] The top end of the water storage tank 7 is of an open design, and a filter plate 18 is detachably provided at the top end of the water storage tank 7. The delivery pump 6 is detachably installed on the filter plate 18.
[0034] A speed reducer 19 is arranged on one side of the water storage tank 7, and the input end of the speed reducer 19 is connected to the output end of the motor 10.

A plurality of tightening wheels 20 are rotatably connected to the outside of the water storage tank 7, and one of the tightening wheels 20 is fixedly connected to the output end of the speed reducer 19.
[0036] In this embodiment, when the temperature of the road surface 1 is relatively high, two transfer pumps 6 are turned on. The transfer pumps 6 pump out the water stored in the water storage tank 7 through the transfer pipes 5 connected to their input ends, and then the pumped water is transported to the main pipe 2 through the transfer pipes 5 connected to the output ends of the transfer pumps 6. Then, the water is transported to each branch pipe 3 through the main pipe 2, and then the water is sprayed onto the road surface 1 through the nozzles 4 connected to the other ends of the branch pipes 3, achieving the cooling and maintenance of the road surface 1. Then, the motors 10 installed on both sides of the water storage tank 7 can be turned on. After being decelerated by the speed reducer 19, the motors 10 drive the tightening wheels 20 connected to the output end of the speed reducer 19 to rotate. Then, the tightening wheels 20 here drive the other tightening wheels 20 and the transmission wheels 12 connected to one side of the turntable 13 to rotate through the transmission belts 11 sleeved on the outside. Then, the turntable 13 drives the movable rod 17 arranged on the other side to rotate. Then, the movable rod 17 drives the support rod 8 to slide along the connecting rod 14 through the cooperation with the movable groove 16 and the movable frame 15. At the same time, the movable rod 17 slides along the movable groove 16 opened on the inner side of the movable frame 15. Then, the support rod 8 drives the main pipe 2 connected to the top end to move up and down reciprocally, thereby driving the branch pipes 3 and the nozzles 4 to move up and down reciprocally, so that the nozzles 4 spray water onto the entire road surface 1, achieving the comprehensive maintenance and cooling treatment of the road surface 1. In this device, the transfer pipes 5 are made of flexible hoses. When the temperature of the road surface 1 is cooled to an appropriate temperature, the motors 10 and the transfer pumps 6 can be turned off.
[0037] Please refer to Figures 1-4 , as an implementation manner of the protection device: The protection device includes a mixing layer 21, a concrete layer 22, a water-proof layer 23, a cushion layer 24, an anti-seepage layer 25, a top layer of the roadbed 26, and a bottom layer of the roadbed 27. The mixing layer 21 is arranged below the road surface 1, the concrete layer 22 is arranged below the mixing layer 21, the water-proof layer 23 is arranged below the concrete layer 22, the cushion layer 24 is arranged below the water-proof layer 23, the anti-seepage layer 25 is arranged below the cushion layer 24, the top layer of the roadbed 26 is arranged below the anti-seepage layer 25, and the bottom layer of the roadbed 27 is arranged below the top layer of the roadbed 26.
[0038] Pipes 28 are provided in the cushion layer 24, and communicating pipes 29 are connected between the pipes 28.
[0039] Connecting pipes 30 are connected above the pipes 28, a communicating chamber 31 is connected to the top ends of the connecting pipes 30, and a water inlet pipe 32 is connected to the top end of the communicating chamber 31.
[0040] Filter holes 33 are opened at the top ends of both the communicating chamber 31 and the water inlet pipe 32.
[0041] More specifically, when using the device in daily life, the road surface 1 is an asphalt layer, and the mixture of asphalt and concrete forms a mixed layer 21. When a vehicle travels on the road, it exerts pressure on the road. Under the support of the bottom roadbed 27, the top roadbed 26, and the cushion layer 24, the roadbed settlement is prevented. When rainwater passes through the road surface 1, most of the rainwater will flow into the communication bin 31 provided on the concrete layer 22 through the water inlet pipe 32 and the filter holes 33 opened at the top of the communication bin 31, and then enter the pipe 28 located in the cushion layer 24 through the connecting pipe 30 connected to the lower end of the communication. When the rainfall is large, the water in the pipe 28 flows into the communicating pipe 29 connected to the pipe 28. The setting of the water-proof layer 23 effectively prevents rainwater from penetrating into the cushion layer 24, and the setting of the anti-seepage layer 25 effectively prevents the moisture contained in the foundation from penetrating into the cushion layer 24, effectively preventing the aging of the entire road surface 1 structure.
[0042] In summary, when the overall device is in use or operation: when the temperature of the road surface 1 is high, turn on the two transfer pumps 6. The transfer pump 6 pumps out the water stored in the water storage tank 7 through the transfer pipe 5 connected to the input end, and then conveys the pumped water to the main pipe 2 through the transfer pipe 5 connected to the output end of the transfer pump 6. Then, the water is conveyed to each branch pipe 3 through the main pipe 2, and then the water is sprayed onto the road surface 1 through the nozzles 4 connected to the other end of the branch pipe 3, realizing the cooling and maintenance of the road surface 1. Then, the motor 10 installed on both sides of the water storage tank 7 can be turned on. After the deceleration of the reducer 19, the motor 10 drives the tightening wheel 20 connected to the output end of the reducer 19 to rotate. Then, the tightening wheel 20 here drives the other tightening wheels 20 and the transmission wheel 12 connected to one side of the turntable 13 to rotate through the transmission belt 11 sleeved on the outside. Then, the turntable 13 drives the movable rod 17 provided on the other side to rotate. Then, the movable rod 17 drives the support rod 8 to slide along the connecting rod 14 through the cooperation with the movable groove 16 and the movable frame 15. At the same time, the movable rod 17 slides along the movable groove 16 opened on the inner side of the movable frame 15. Then, the support rod 8 drives the main pipe 2 connected to the top to move up and down reciprocally, thereby driving the branch pipe 3 and the nozzle 4 to move up and down reciprocally, so that the nozzle 4 sprays water onto the entire road surface 1, realizing the comprehensive maintenance and cooling treatment of the road surface 1. In this device, the transfer pipe 5 is made of a flexible hose. When the temperature of the road surface 1 is cooled to an appropriate temperature, turn off the motor 10 and the transfer pump 6.
[0043] During the daily use of the device, the road surface 1 is an asphalt layer, and the mixture of asphalt and concrete forms a mixed layer 21. When a vehicle travels on the road, it squeezes the road. Under the support of the bottom layer 27 of the roadbed, the top layer 26 of the roadbed and the cushion layer 24, the settlement of the roadbed is prevented. When rainwater passes through the road surface 1, most of the rainwater will flow into the communication bin 31 provided on the concrete layer 22 through the water inlet pipe 32 and the filter holes 33 opened at the top of the communication bin 31, and then enter the pipe 28 located in the cushion layer 24 through the connecting pipe 30 connected to the lower end of the communication. When the rainfall is large, the water in the pipe 28 flows into the communicating pipe 29 connected to the pipe 28. The setting of the waterproof layer 23 effectively prevents rainwater from penetrating into the cushion layer 24, and the setting of the anti-seepage layer 25 effectively prevents the moisture contained in the foundation from penetrating into the cushion layer 24, effectively preventing the aging of the entire road surface 1 structure.
[0044] In all the solutions mentioned above, for the connection between two components, welding, the cooperation of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
