Abstract
Description
Technical Field
[0001] This invention relates to the field of roadbed construction, specifically to a construction method for highways, pavement structures, and highway pavements. Background Technology
[0002] Currently, my country's highway structure is mainly composed of asphalt and concrete. When laying asphalt pavement, a paver is used to spread the asphalt, then a steel wheel roller is used to compact it, and then a rubber wheel is used to compact it, thus completing the laying of the asphalt pavement.
[0003] When using rubber-tired rollers to compact asphalt pavements, the rubber tires easily pick up stones mixed with asphalt, causing potholes and affecting pavement quality. Initially, workers coated the tires with anti-sticking agents like cooking oil or engine oil. However, this method was cumbersome and posed a safety hazard as workers had to operate the rollers close to the machine. Later, scrapers and spray nozzles were used to prevent stone adhesion. While scrapers clean the stones from the tires, this process caused stones to accumulate on the scraper, leading to re-adhesion and poor cleaning. Spray nozzles... The spraying method mainly involves spraying an anti-sticking agent onto the rubber wheels to prevent stones from adhering, which can achieve a good anti-sticking effect. However, the effectiveness of the anti-sticking agent is affected by factors such as weather and environment. For example, in a dusty working environment, the anti-sticking agent will degrade quickly, and in hot weather, the anti-sticking agent will also degrade quickly. Therefore, when using the nozzle spraying method, it is usually necessary to continuously spray the anti-sticking agent to ensure that the rubber wheels do not stick to stones. However, continuous spraying is unnecessary. Continuous spraying will lead to waste of anti-sticking agent, increase the cost of use, and excessive spraying of anti-sticking agent will cause the anti-sticking agent to flow onto the road surface. Anti-sticking agent has a certain dissolving effect on asphalt, and anti-sticking agent flowing onto the road surface will reduce the adhesion of the asphalt, thereby affecting the quality of the asphalt pavement.
[0004] Therefore, in order to improve the anti-sticking effect of rubber tires without affecting the road surface quality, a construction method for highways, road surface structures, and highway pavements is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a construction method for highways, road structures, and highway pavements. By installing a cleaning device on the frame, cleaning the stones after they adhere to the rubber wheels, and then spraying an anti-sticking agent onto the rubber wheels, the problems mentioned in the background art can be solved.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A construction method for highways, pavement structures, and highway pavements includes the following steps:
[0008] S1. First, use a paver to pave the road surface;
[0009] S2. Start the steel wheel roller to compact the road surface;
[0010] S3. Start the rubber-tired roller to compact the road surface;
[0011] S4. The cleaning device is activated to clean the stones adhering to the rubber wheels and to prevent the rubber wheels from sticking.
[0012] S5. After working for 20-30 seconds, the cleaning device stops.
[0013] The rubber-tired roller includes a frame and multiple rubber tires, which are rotatably mounted on the frame. The frame is equipped with a drive device for driving the rubber tires to rotate, and the cleaning device is mounted on the frame.
[0014] Preferably, the cleaning device includes an atomizing nozzle mounted on a frame, and the frame is equipped with a feeding device for supplying anti-sticking agent to the atomizing nozzle. The feeding device uses an oil tank and an oil pump to supply oil. The oil tank is welded to the frame, and the oil pump is screwed to the oil tank. There are multiple methods, as long as the anti-sticking agent is supplied to the atomizing nozzle. The anti-sticking agent is an organic solvent such as machine oil or edible oil. The atomizing nozzle is connected to the feeding device through a pipe, which is a flexible hose such as a steel wire braided rubber hose or a nylon resin hose. A mounting plate is welded to the frame, and a scraper is rotatably mounted on the mounting plate via a rotating shaft. A magnet is glued to the scraper, and a second magnet is provided on the frame that attracts the first magnet. A switch is provided on the frame that is in contact with the scraper, and the switch is wired to the feeding device. A reset component for resetting the scraper is connected to the scraper.
[0015] By using a scraper, stones adhering to the rubber wheel are cleaned. When the stones are strongly adhered, the scraper, under the force of the stones, detaches from the magnet, causing it to rotate. Upon contact with the rubber wheel, the scraper deforms, resulting in a tighter fit and thus cleaning even strongly adhered stones. After rotation, the scraper disengages from the switch, triggering it to activate the feeding device, providing anti-sticking agent to the atomizing nozzle. This agent is then applied to the rubber wheel surface to further prevent sticking. Finally, a reset assembly returns the scraper to its original position. By setting a rotating scraper and triggering a switch to control the feeding device to apply anti-sticking agent to the rubber wheel, the scraper can promptly apply anti-sticking agent to the rubber wheel after stones adhere to it, thus effectively reducing the amount of anti-sticking agent used and its impact on the road. The scraper also cleans the stones already adhering to the rubber wheel, preventing them from damaging the road. Furthermore, a reset component resets the scraper, reducing friction between the scraper and the rubber wheel, extending the scraper's service life, and reducing stone accumulation at the scraper, preventing stone buildup from affecting the stone cleaning effect.
[0016] Preferably, the reset assembly includes a pressure cylinder mounted on a mounting plate, and the inside of the pressure cylinder is divided into a pressure chamber and an air chamber by a first partition and a second partition. The pipe is connected to the atomizing nozzle through the pressure chamber, and the air chamber is connected to the external atmosphere. The first partition is integrally connected inside the pressure cylinder, and the second partition is movably installed inside the pressure cylinder and connected to a rotating shaft. The pressure cylinder is provided with a timing component to prevent the scraper from quickly resetting and to improve the anti-sticking agent spraying time.
[0017] By setting up a pressure cylinder, and connecting it to the pressure chamber inside the pressure cylinder through a pipe, and then connecting it to the atomizing nozzle through another pipe, when the feeding device is started, the anti-sticking agent first passes through the pressure chamber and then through the atomizing nozzle, causing pressure to be generated inside the pressure chamber and pushing the second partition to rotate. The second partition drives the rotating shaft to rotate, thereby realizing the reset of the scraper. The air chamber is connected to the outside air to avoid the pressure cylinder being in a negative pressure state, which would affect the rotation of the scraper.
[0018] In this invention, a motor can also be used to reset the scraper. However, using a motor to reset the scraper increases the manufacturing cost of the cleaning device. Furthermore, when using a motor, the mud, asphalt, and other impurities kicked up by the rubber-tired roller during operation will splash onto the motor. These impurities will adhere to the motor surface, affecting heat dissipation. When the rubber-tired roller travels on muddy roads, water will splash onto the motor, which may cause a short circuit and damage during operation, resulting in unnecessary losses and posing certain safety hazards. In contrast, using a feeding device to reset the scraper eliminates these safety hazards during use. Moreover, the pressure generated by the feeding device drives the scraper, allowing for the reuse of its energy and reducing the operating cost of the cleaning device.
[0019] However, when using the feeding device to drive the scraper to reset, the scraper resets quickly during the feeding process, causing it to quickly contact the switch and shut down the feeding device. This results in insufficient spraying time for the atomizing nozzle, preventing the rubber roller from being fully coated with enough anti-sticking agent. Although setting a delay control for the feeding device can evenly coat the rubber roller surface with anti-sticking agent, the rapid reset of the scraper prevents the rubber roller from being thoroughly cleaned, leaving stones that may still adhere to it. This can damage the road when the rubber roller is working. Therefore, by setting a timing component, the working time of the feeding device can be increased while ensuring that the rubber roller is coated with enough lubricating oil and allowing the scraper to reset with a delay for thorough cleaning of the rubber roller surface.
[0020] Preferably, the timing component includes a one-way damper mounted on the outer wall of the pressure cylinder, and the one-way damper is connected to the rotating shaft.
[0021] By connecting a one-way damper to the rotating shaft, when the oil supply assembly provides pressurized anti-sticking agent to the pressure cylinder, the rotating shaft slowly resets under the action of the one-way damper. This increases the working time of the feeding device while delaying the reset of the scraper. The one-way damper has a simple structure, is easy to install, and does not affect the rotation of the scraper when it is cleaning stones.
[0022] Preferably, the frame includes a blocking cover, which is mounted on the frame. The blocking cover is in contact with the rotating shaft and the mounting plate, and the switch and magnet are both mounted on the blocking cover.
[0023] During operation, rubber-tired rollers carry asphalt and mud debris, which can splash onto the switch, preventing the scraper from fully resetting and thus preventing the switch from triggering. This necessitates regular cleaning of the switch area. Furthermore, after rain or on muddy roads, the rubber tires accumulate more mud, causing significant mud splashing and rapid buildup at the switch area. Before regular cleaning, this mud can prevent the scraper from resetting and triggering the switch. Therefore, to prevent mud, asphalt, and other debris from adhering to the frame at the switch area, a protective cover is installed. This cover, along with the mounting plate and shaft, forms a sealed cavity, effectively preventing mud from splashing onto the switch.
[0024] Preferably, a positioning block is installed on the frame, a magnet three is provided on the positioning block, and a magnet four is provided on the scraper that attracts the magnet three.
[0025] Preferably, the upper surface of the positioning block is inclined, and the height of the positioning block on the side closer to the rubber wheel is greater than the height on the side farther away from the rubber wheel.
[0026] Preferably, the positioning block is slidably mounted on the mounting plate, and a spring is connected between the positioning block and the mounting plate, and an inclined surface is provided at the front end of the positioning block.
[0027] During use, the rotation of the scraper is usually accompanied by the deformation of the scraper. After the scraper is deformed multiple times, it will undergo a certain amount of plastic deformation and will not be able to return to its original state. This will cause the scraper to come into direct contact with the rubber wheel, which will aggravate the wear of the scraper. To address this, a positioning block is installed on the frame, and a magnet is installed on the positioning block. After the positioning block is reset, the magnet will attract the magnet, making the scraper stick tightly to the positioning block. This ensures that the scraper and the rubber wheel can always maintain a small distance, but without direct friction between them, thereby improving the service life of the scraper.
[0028] During use, the rotation of the rubber wheel will cause dirt and asphalt impurities to splash, resulting in the accumulation of impurities on the positioning block. After the scraper resets, the distance between the scraper and the rubber wheel will increase, making it impossible for the scraper to clean the stones on the rubber wheel, thus causing the cleaning device to fail. To address this, the upper surface of the positioning block is made inclined, and the height of the side of the positioning block closer to the rubber wheel is greater than the height of the side farther away from the rubber wheel. After the scraper contacts the positioning block, the magnet attracts the scraper again. Due to the inclination of the upper surface, the contact area between the scraper and the positioning block is small at this time. Therefore, the scraper will squeeze the impurities on the surface of the positioning block, causing the impurities on the scraper surface to be squeezed away, so that the scraper can always contact the positioning block and maintain a certain height.
[0029] During use, the scraper may deform and detach from the positioning block during rotation. However, during the reset process, the scraper may be squeezed and deformed by the positioning block, making it unable to return to its original position and constantly adhering to the rubber wheel, resulting in friction and reduced service life. To address this, the positioning block is slidably mounted on the mounting plate. When the positioning block is reset, the scraper pushes the positioning block to retract. After the scraper returns to its original position, the positioning block pops out under the action of the spring and moves to the bottom of the scraper to attract the scraper, keeping the scraper at a certain height.
[0030] When the scraper is deformed, the height of the scraper below is lower than that of the positioning block, and it cannot rotate to be above the positioning block, thus failing to complete the reset. Therefore, the front of the positioning block is set as an inclined surface, and the lowest point of the inclined surface is lower than the height of the rubber wheel, so as to ensure that the positioning block is always lower than the scraper and that the scraper can be reset.
[0031] During use, in order to prevent impurities from the mixture of soil and asphalt from solidifying and causing the scraper to be unable to remove the impurities, the positioning block needs to be placed within the spraying range of the atomizing nozzle. By spraying an anti-sticking agent onto the positioning block, the asphalt can be prevented from solidifying.
[0032] Preferably, the scraper is at an angle of 10°-20° to the vertical direction, and the atomizing nozzle is located above the scraper.
[0033] During use, scrapers can accumulate asphalt-laden stones. These stones restrict the scraper's rotation when cleaning the stones and can cause them to re-adhere to the rubber-tired rollers, leading to damage to the road during operation. To address this, the scraper is tilted to the vertical, with the atomizing nozzle positioned above it. When the nozzle operates, some anti-sticking agent is sprayed onto the scraper to prevent stones from adhering. The angle is set to ensure the anti-sticking agent is sprayed onto the scraper more effectively. However, a large tilt angle results in a large scraper rotation angle and deformation. Therefore, the scraper tilt angle is set between 10° and 20°.
[0034] A highway and pavement structure manufactured according to a highway pavement construction method includes a roadbed, on which a slag layer is laid, and on the slag layer a compacted and regular gravel base layer is laid, on the base layer an epoxy resin asphalt layer is laid, with 1-1.2 kg of epoxy resin asphalt layer laid per square meter, and on the epoxy resin asphalt layer a modified asphalt concrete pavement layer is laid, with the asphalt to concrete ratio of the asphalt to concrete in the asphalt concrete pavement layer being 5:100, and a number of equally spaced speed bump components are embedded in the modified asphalt concrete pavement layer.
[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0036] 1. The present invention discloses a construction method for highways, road surface structures, and highway pavements. By installing a rotating scraper on a frame and controlling a feeding device to apply an anti-sticking agent to the rubber wheel via a switch triggered by the rotation of the scraper, the anti-sticking agent can be applied to the rubber wheel promptly after stones adhere to it, effectively reducing the amount of anti-sticking agent used and minimizing its impact on the highway. The scraper also cleans stones already adhering to the rubber wheel, preventing damage to the highway. Furthermore, a reset component resets the scraper, reducing friction between the scraper and the rubber wheel and extending the scraper's service life. An atomizing nozzle located above the scraper sprays anti-sticking agent onto both the rubber wheel and the scraper simultaneously, preventing asphalt and stones from adhering to the scraper and affecting its cleaning effect.
[0037] 2. The construction method for highways, road surface structures, and highway pavements described in this invention, by connecting a reset component on a rotating shaft, allows the scraper to reset under the power of the feeding device, reducing the need for an external power source and lowering manufacturing costs. Furthermore, by installing a one-way damper on the rotating shaft, the working time of the feeding device is increased, ensuring that the surface of the rubber wheel is fully coated with anti-sticking agent while allowing the scraper to reset after a delay, thus thoroughly cleaning the surface of the rubber wheel. This avoids incomplete cleaning by the scraper and inadequate application of anti-sticking agent to the rubber wheel, which would lead to frequent starts of the cleaning device and reduce its service life.
[0038] 3. The construction method for highway, road surface structure and highway pavement described in this invention uses positioning blocks on the frame and magnets on the positioning blocks to attract three pairs of scrapers. This ensures that the scrapers maintain a certain distance from the rubber wheel even after deformation, preventing the scrapers from constantly contacting the rubber wheel and reducing their wear life. Furthermore, by setting the positioning blocks as inclined surfaces, impurities on the positioning blocks are squeezed away when the scrapers are attracted, preventing the rubber wheel from carrying dirt, asphalt, and other impurities onto the positioning blocks, which would increase the height of the positioning blocks, leading to inaccurate scraper positioning and causing the scraper to be too far from the rubber wheel, thus preventing the cleaning device from working properly.

[0050] Example 1, as Figures 1 to 10 As shown in the figure, this embodiment illustrates the operation of a rubber-tired roller as follows:
[0051] A method for constructing a highway pavement, comprising:
[0052] S1. First, use a paver to pave the road surface;
[0053] S2. Start the steel wheel roller to compact the road surface;
[0054] S3. Start the rubber-tired roller to compact the road surface;
[0055] S4. The cleaning device is started to clean the stones adhering to the rubber wheel 2 and to prevent the rubber wheel 2 from sticking.
[0056] S5. After 20 seconds of operation, the cleaning device stops.
[0057] The rubber-tired roller includes a frame 1 and four rubber-tired rollers 2. The four rubber-tired rollers 2 are rotatably mounted on the frame 1. The frame 1 is equipped with a drive device for driving the rotation of the rubber-tired rollers 2. The drive device is a diesel engine. A cleaning device is mounted on the frame 1 and includes atomizing nozzles 3 mounted on the frame 1. The frame 1 is also equipped with a feeding device 4 for supplying anti-sticking agent to the atomizing nozzles 3. The feeding device 4 uses an oil tank and an oil pump to supply oil. The oil tank is welded to the frame 1, and the oil pump is screwed to the oil tank. The anti-sticking agent is edible oil. The atomizing nozzles... 3 is connected to the feeding device 4 via pipe 13, which is a steel wire braided rubber hose. Two mounting plates 5 are welded to the frame 1, symmetrically mounted on it. Scrapers 6 are rotatably mounted on the mounting plates 5 via a rotating shaft 28. Magnets 7 are glued to the scrapers 6. A blocking cover 17 is bolted to the frame 1, and a switch 9 is installed on the blocking cover 17 to control the start and stop of the feeding device 4. A second magnet 8, which cooperates with magnet 7, is also installed on the blocking cover 17. The blocking cover 17 is respectively attached to the mounting plates 5 and the rotating shaft 28, forming a... A closed cavity is formed, and a reset assembly for resetting the scraper 6 is connected to the scraper 6. The reset assembly includes a pressure cylinder 10 mounted on the mounting plate 5, and the inside of the pressure cylinder 10 is divided into a pressure chamber 11 and an air chamber 12 by a partition 14 and a partition 15. The pipe 13 is connected to the atomizing nozzle 3 through the pressure chamber 11, and the air chamber 12 is connected to the atmosphere. The partition 14 is integrally connected to the inside of the pressure cylinder 10, and the partition 15 is movably installed inside the pressure cylinder 10 and connected to the rotating shaft 28. The pressure cylinder 10 is provided with a preventive device. The timing component for quick reset of the scraper 6 to improve the spraying time of the anti-sticking agent includes a one-way damper 16 installed on the outer wall of the pressure cylinder 10 and connected to the rotating shaft 28. A positioning block 18 is hinged on the frame 1. A magnet 3 19 is provided on the positioning block 18. A magnet 4 20 is provided on the scraper 6 and attracts the magnet 3 19. The side of the positioning block 18 near the installation and the side near the scraper 6 are both inclined surfaces. The positioning block 18 is slidably installed on the mounting plate 5 and a spring 21 is connected between the positioning block 18 and the mounting plate 5.
[0058] A highway and pavement structure manufactured according to a highway pavement construction method includes a roadbed 22, a soil layer 23 laid on the roadbed 22, a compacted and regular stone base layer 24 laid on the soil layer 23, an epoxy resin asphalt layer 25 laid on the base layer 24, the epoxy resin asphalt layer 25 being laid at 1.2 kg per square meter, a modified asphalt concrete pavement layer 26 laid on the epoxy resin asphalt layer 25, the asphalt to concrete ratio of the modified asphalt concrete pavement layer 26 being 5:100, the asphalt pavement thickness being 6 cm, and a number of equally spaced speed bump components 27 embedded on the modified asphalt concrete pavement layer 26.
[0059] Before operation, add anti-sticking agent to the oil tank and clean the surface of scraper 6. During operation, the rubber-tired roller needs to be kept stopped to avoid safety accidents. After operation, the rubber-tired roller can be used to compact the road.
[0060] After the rubber-tired roller starts running, the feeding device 4 will start first to spray anti-sticking agent on the rubber tire 2 to prevent the rubber tire 2 from sticking with stones when it starts working, thus reducing the number of cleaning times of the scraper 6. After spraying for 20 seconds, the feeding device 4 will stop working, and the rubber-tired roller will start to compact the asphalt pavement.
[0061] After the rubber-tired roller has been working for a certain period of time, the anti-sticking agent on the rubber tire 2 begins to fail. Asphalt-coated stones on the asphalt pavement will adhere to the rubber tire 2. When the stones rotate to the scraper 6, the scraper 6 will push the stones to clean them, preventing the rubber tire 2 from squeezing the asphalt pavement during operation and causing pits, thus affecting the road quality. When the anti-sticking agent's effectiveness further decreases, the asphalt adhesion increases, and the stones will push the scraper 6 to rotate, causing the scraper 6 to adhere to the rubber tire 2. At this time, the scraper 6 moves away from the switch 9, and the switch 9 activates the feeding device 4, supplying material to the atomizing nozzle 3 through the pipe 13. An anti-sticking agent is sprayed onto the rubber wheel 2. During the spraying process, the anti-sticking agent first enters the pressure chamber 11 inside the pressure cylinder 10, generating a certain pressure and pushing the partition plate 15 to rotate around the rotating shaft 28, thereby driving the scraper 6 to reset. The rotating shaft 28 is connected to a one-way damper 16. When the scraper 6 rotates for cleaning, the scraper 6 can rotate quickly. When the scraper 6 rotates to reset, the scraper 6 rotates slowly under the action of the one-way damper 16, which plays a timing role. Finally, the scraper 6 thoroughly cleans the rubber wheel 2, and the rubber wheel 2 can be sprayed with enough anti-sticking agent, thereby reducing the start frequency of the cleaning device.
[0062] During use, the feeding device 4 needs to be controlled by the rotation speed of the rubber-tired roller 2. When the rubber-tired roller stops working, even if the scraper 6 is far away from the switch 9 and the feeding device 4 is in a stopped state, the feeding device 4 should not continue to work when the rubber-tired roller stops working. This would not only prevent the rubber-tired roller 2 from being fully coated, resulting in a waste of anti-sticking agent, but would also cause the scraper 6 to reset when not working, causing the scraper 6 to rotate again when the rubber-tired roller starts working again, thus increasing the start frequency of the cleaning device.
[0063] Example 2, as Figures 1 to 10 As shown, this embodiment illustrates the operation of a rubber-tired roller on a dirt road surface, as detailed below:
[0064] In Embodiment 2, a control switch for separate control of the cleaning device is installed inside the cab of the rubber-tired roller. When the rubber-tired roller is traveling on a dirt road, the cleaning device can be controlled separately through the control switch to prevent the cleaning device from starting to work when stopping or starting. When traveling on a dirt road, although the rubber tire 2 will stick to the dirt, the viscosity of the dirt is low and it cannot push the scraper 6 away from the attraction of the magnet 2 8. Therefore, there is no need to consider that the scraper 6 will rotate and cannot return to its original position when it is not working.
[0065] For any implementation methods not mentioned in Example 2, they are the same as in Example 1, and will not be described in detail here.
[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
