Description

Technical Field

[0001] This invention belongs to the field of colored permeable pavement, and specifically relates to a construction system and construction method for high-toughness permeable colored composite pavement. Background Technology

[0002] Permeable colored pavement is widely used in urban sightseeing roads, park trails, and scenic area roads. However, the existing construction process faces two major technical challenges: First, the level of mechanization is low, especially in the process of applying thick coatings, which mainly relies on manual operation. Workers repeatedly scrape the wet material surface with a scraper, resulting in high labor intensity, low efficiency, and difficulty in ensuring uniform coating thickness. Second, there is a lack of real-time thickness control mechanisms. Manual scraping cannot dynamically adjust the scraper height according to the undulations of the substrate, and the coating thickness deviation usually exceeds ±3mm. This leads to unstable permeability, insufficient interlayer bonding strength, and early-stage peeling, fading, and other quality problems, failing to meet the construction requirements of high-durability colored pavement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-toughness permeable colored composite pavement construction system and its construction method. This system integrates a paving device, a viscous material spraying device, a scraping device, a texture compaction device and a thickness measurement system on the same mobile frame, realizing integrated construction of the entire process from the base layer to the protective layer. This avoids the time waste and connection problems of traditional multi-equipment alternating operations, and greatly improves construction efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A high-toughness, permeable colored composite pavement construction system includes a paving device, a viscous material spraying device, a scraper device, a texture compaction device, and a thickness measurement system, wherein the paving device, the viscous material spraying device, the scraper device, the texture compaction device, and the thickness measurement system are mounted on a mobile frame device.

The telescopic end of the scraper drive cylinder is connected to the scraper. The scraper drive cylinder is used to drive the scraper to actively scrape the material.

[0009] As a preferred embodiment, the system also includes a paint overflow prevention device, which includes a suction head installed on the scraper. The suction head is installed on the edge of the scraper end, and at least one suction head is provided at both ends of the scraper. The suction head is connected to the manifold box through a transfer pipe. The manifold box is located in the middle of the scraper, and a discharge port is provided at the bottom of the manifold box. A suction pump is provided on the manifold box, which is used to transfer excess paint from both ends of the scraper to the middle of the scraper.

[0010] As a preferred embodiment, the texture compaction device includes a hammer plate, which is driven to move up and down by a hammer plate drive cylinder, which is mounted on the middle crossbeam of the vehicle frame; the bottom surface of the hammer plate is provided with a textured shape, which includes a sawtooth shape, a wave shape, or a concave-convex shape.

[0011] As a preferred embodiment, both the front and rear measurement sensor matrices consist of multiple laser rangefinders, which are mounted on the vehicle frame via sensor mounting plates. The front and rear measurement sensor matrices calculate the thickness of the viscous coating by measuring the height difference of the measured surface.

[0012] As a preferred embodiment, the independent driving device includes at least four sets, which are respectively used to be installed at the end or edge of the frame. The independent driving device includes a track wheel assembly, which is connected to the driving motor through a sprocket and a chain. Both the track wheel assembly and the travel drive motor are mounted on the wheel support frame. The wheel support frame is connected to the bushing via a rotating shaft. A steering hoop is mounted on the outside of the rotating shaft. The steering hoop is driven by a steering cylinder, which is rotatably mounted on the frame.

[0013] As a preferred embodiment, the system also includes a speed sensor and a main controller. The speed sensor is used to measure the travel speed of the mobile frame device. The speed sensor, the front measurement sensor matrix, and the rear measurement sensor matrix are connected to the signal input terminal of the main controller. The output terminal of the main controller is connected to the drive cylinder or actuator of the paving device, the viscous material spraying device, the scraping device, and the texture compaction device. The drive cylinder includes a horizontal plate lifting cylinder and a scraper drive cylinder.

[0014] The construction method of the high-toughness permeable colored composite pavement construction system includes the following steps: S1. Construction of the foundation layer: The original soil compaction layer is constructed using a compactor. After the crushed stone drainage layer and permeable concrete buffer layer are laid separately using a paving device, a textured compaction device is used to treat the texture, followed by curing. S2. Construction of high-bonding transition layer: Position the mobile frame device to the construction starting point, lower the viscous material spraying device to the working position, and adjust the working height according to the type of viscous material; at this time, the viscous material is a high-adhesion transition material. Start the feed pump and adjust the discharge speed of each nozzle through the flow control valve group to spray the viscous material evenly onto the base surface; Simultaneously, the scraping device is activated, and the main controller sets the moving frame device travel speed V1 and the scraper drive cylinder extension speed V2 according to preset parameters, keeping V1=V2. When the scraper drive cylinder extends to its maximum stroke, it quickly retracts to its initial position and then continues to extend at a speed of V2, forming a continuous intermittent scraping action. The thickness measurement system works in real time. The front measurement sensor matrix measures the average height L1 of the front base surface, and the rear measurement sensor matrix measures the average height L2 of the leveled surface. The main controller calculates the height difference △L=L1-L2, and automatically adjusts the horizontal plate lifting cylinder to change the scraper height according to the set target thickness D, with a control accuracy of ±1mm; The paint overflow prevention device works simultaneously to prevent material from overflowing from the edge of the scraper; S3, Colored Functional Surface Layer Construction: After completing the curing of the high-adhesion transition layer, raise the viscous material spraying device and scraper to a non-working position; lower the height of the paving device and pave the colored functional surface layer; perform necessary cleaning and expansion joint cutting; and carry out curing. S4, Fluorocarbon-silane composite protective layer construction: Fluorocarbon silane composite protective material is evenly sprayed onto the colored functional surface layer using a thick material spraying device; After the S5 and fluorocarbon-silane composite protective layer are constructed, they are cured in stages, and finally, a quality acceptance test is conducted.

[0015] A high-toughness, permeable, colored composite pavement structure, comprising: The original soil compaction layer is used to provide foundation bearing capacity and control settlement, serving as the supporting foundation for the entire pavement system; The gravel drainage layer is used to quickly drain seepage water and prevent water accumulation, while also dispersing the load from above. The permeable concrete buffer layer is used to store water and filter rainwater, and to buffer the impact of the upper load on the base layer. A high-adhesion transition layer is used to eliminate abrupt changes in interlayer modulus, enhance interlayer bond strength, and improve overall toughness; The colored functional surface layer provides a decorative and aesthetically pleasing effect, while also offering high wear resistance and anti-slip safety features; Fluorocarbon-silane composite protective layer is used for UV protection and antifouling and anti-seepage, enhancing surface hardness and maintaining water permeability.

[0016] The present invention can achieve the following beneficial effects: 1. This system integrates the paving device, the viscous material spraying device, the scraping device, the texture compaction device, and the thickness measurement system onto the same mobile frame, realizing integrated construction of the entire process from the base layer to the protective layer. This avoids the time waste and connection problems of traditional multi-equipment alternating operations, and greatly improves construction efficiency.

[0017] 2. A front and rear measurement sensor matrix is ​​used to monitor the height difference between the substrate and the coating surface in real time. The height of the scraper is dynamically adjusted by the main controller to achieve coating thickness control accuracy, which significantly improves coating uniformity and functional stability.

[0018] 3. By controlling the travel speed V1 of the moving frame to be equal to the extension speed V2 of the scraper drive cylinder, the scraper is kept relatively stationary relative to the ground, forming a continuous intermittent scraping action, which solves the problem of uneven surface caused by the traditional "scraping once and retracting once" and improves the smoothness of the coating surface.

[0019] 4. The paint overflow prevention device uses a negative pressure system consisting of a suction head, a transfer pipe, and a suction pump to transfer excess paint overflowing from the edge of the scraper to the center, effectively preventing the common problem of the edge thickness being greater than the center thickness, ensuring uniform coating thickness distribution, and reducing material waste.

[0020] 5. Each functional device is equipped with an independent lifting mechanism, which can flexibly switch working states according to the needs of the construction stage. For example, when paving the colored functional surface layer, the thick material spraying device and scraping device can be raised to the non-working position to avoid mutual interference, thereby improving equipment utilization and construction flexibility.

[0021] 6. Based on feedback data from the speed sensor and thickness measurement system, the main controller can automatically adjust the parameters of each actuator to adapt to different viscous material characteristics and surface undulations, reducing reliance on operator skills and improving construction quality.

[0024] Example 1: Preferred solutions include Figures 1 to 4 As shown, a high-toughness permeable colored composite pavement construction system includes a paving device 1, a viscous material spraying device 2, a scraper device 3, a texture compaction device 4, and a thickness measurement system 5. The paving device 1, the viscous material spraying device 2, the scraper device 3, the texture compaction device 4, and the thickness measurement system 5 are mounted on a mobile frame device 6. The mobile frame device 6 includes a frame 6.1, on which multiple independent driving devices 6.2 are installed. The frame 6.1 is also equipped with a paving device 1, a viscous material spraying device 2, a scraping device 3, a texture compaction device 4, and a thickness measurement system 5. The paving device 1 is used for paving the functional layer of the road; in this embodiment, the functional layer includes a crushed stone drainage layer, a permeable concrete buffer layer and a colored functional surface layer; the colored functional surface layer uses weather-resistant colored ceramic particles as aggregate, combined with white silicate cement and nano-silica, and the surface is treated to achieve anti-slip safety effect.

[0025] The aforementioned viscous material spraying device 2 is used to spray the viscous material; the viscous material includes a high-adhesion transition layer and a fluorocarbon-silane composite protective layer. The high-adhesion transition layer enhances interlayer adhesion strength by adding nano-active SiO2 and polymer modifiers, ensuring an adhesion strength ≥0.8 MPa with the upper and lower layers. The fluorocarbon-silane composite protective layer is an organic-inorganic hybrid protective agent that effectively prevents UV erosion and oil penetration while maintaining water permeability.

[0026] The textured compaction device 4 is used to hammer textures onto the surface of the functional layer; for example, hammering a serrated texture onto the surface of a permeable concrete buffer layer, and then spraying a high-adhesion transition layer. This can enhance the interlayer bond strength, eliminate abrupt changes in interlayer modulus, and improve overall toughness.

[0027] The thickness measurement system 5 includes a front measurement sensor matrix 51 and a rear measurement sensor matrix 52, which are used together to calculate the coating thickness of the viscous coating. Due to the poor flowability of the viscous material, after spraying, it needs to be smoothed by a scraper device 3 to form a smooth viscous coating. The installation height of the scraper in the scraper device 3 is the main factor determining the thickness of the viscous coating; when the thickness of the viscous coating is unqualified, the height of the scraper needs to be adjusted. In this solution, the front measurement sensor matrix 51 and the rear measurement sensor matrix 52 are used to monitor the thickness of the viscous coating in real time. The viscous coating in this embodiment is a high-adhesion transition layer, but any similar morphology suitable for scraping falls within the scope of protection of this invention. For example, if the fluorocarbon-silane composite protective layer is thin, the scraper device 3 is not needed; if the fluorocarbon-silane composite protective layer is thick, the scraper device 3 can be used. The terms "thinner" and "thicker" here are determined by the control precision of the scraping device 3. If the thickness of the fluorocarbon-silane composite protective layer is less than 1 mm, the scraping device 3 is not required, and the viscous material spraying device 2 can be used to spray it evenly.

[0028] Specifically, the paving device 1 in this embodiment includes a feeding hopper 1.1, and a screw spreader 1.2 is provided at the bottom of the feeding hopper 1.1. The two ends of the screw spreader 1.2 are respectively connected to the lifting side plate 1.3. The lifting side plate 1.3 is driven to move up and down by the lifting cylinder 1.4 of the screw spreader. The lifting cylinder 1.4 of the screw spreader is installed on the frame 6.1.

[0029] The paving device 1 in this embodiment is similar to the paving structure of existing pavers, except that the auger paver 1.2 of this invention can be raised and lowered. Its advantages are: first, when the viscous material spraying device 2, scraping device 3, and texture compaction device 4 are working, the auger paver 1.2 can be raised to avoid interfering with the operation of other devices; second, the paving device 1 can pave more than one type of material, and different materials have different paving thicknesses, so different heights can be switched for different materials.

[0030] Specifically, the viscous material spraying device 2 in this embodiment includes multiple spray heads 2.1, which are linearly mounted on a lifting bracket 2.2. The lifting bracket 2.2 is driven to move up and down by a spray head lifting cylinder 2.3, which is mounted on a frame 6.1.

[0031] Specifically, in this embodiment, the lifting bracket 2.2 is equipped with a material pump mounting bracket and a paint mounting bracket. The material pump mounting bracket is equipped with a material pump 2.4, and the paint mounting bracket is equipped with a paint tank 2.5. The material pump 2.4 is connected to the spray head 2.1 through a material delivery pipe and a flow control valve group.

[0032] like Figure 1 , Figure 5 As shown, multiple spray heads 2.1 are linearly installed in the middle of the frame 6.1. A paving device 1 is installed at the front end of the viscous material spraying device 2, a scraping device 3 is installed at the rear end of the viscous material spraying device 2, and a texture compaction device 4 is installed at the rear end of the scraping device 3.

[0033] The spray head 2.1 adopts a liftable design. Its purpose is that when the viscous material spraying device 2 is not working, the spray head 2.1 and the material conveying pipe, flow control valve group, material pump 2.4 connected to the spray head 2.1 are all raised to the top with the lifting bracket 2.2 to avoid interfering with the operation of the paving device 1.

[0034] Specifically, the scraping device 3 in this embodiment includes a horizontal plate lifting cylinder 3.1 installed on the frame 6.1. The horizontal plate lifting cylinder 3.1 is used to drive the horizontal plate 3.2 to move up and down. A scraper drive cylinder 3.3 is installed on the horizontal plate 3.2. The telescopic end of the scraper drive cylinder 3.3 is connected to the scraper 3.4. The scraper drive cylinder 3.3 is used to drive the scraper 3.4 to actively scrape the material.

[0035] like Figure 6 , 7 As shown, the scraper 3.4 can be moved up and down by the horizontal plate lifting cylinder 3.1 to adjust the height of the scraper 3.4, thereby controlling the thickness of the viscous coating. The scraper drive cylinder 3.3 is used to drive the scraper 3.4 to move horizontally, simulating the action of manual scraping.

[0036] Specifically, the system also includes a paint overflow prevention device 7, which includes a suction head 7.1 installed on the scraper 3.4. The suction head 7.1 is installed on the edge of the end of the scraper 3.4, and at least one suction head 7.1 is provided at both ends of the scraper 3.4. The suction head 7.1 is connected to the manifold 7.3 through the transfer pipe 7.2. The manifold 7.3 is located in the middle of the scraper 3.4, and the bottom of the manifold 7.3 is provided with a discharge port. The manifold 7.3 is provided with a suction pump 7.4, which is used to transfer excess paint from both ends of the scraper 3.4 to the middle of the scraper 3.4.

[0037] A gap exists between the scraper 3.4 and the side baffle 6.3 of the mobile frame device 6 to ensure smooth operation of the scraper 3.4. However, this gap can cause leakage of viscous material at this location, especially when the viscous material spraying device 2 provides a large amount of material. A significant amount of material will leak from the front end of the scraper 3.4 to its rear end, resulting in a thicker coating at the edge than in the center. To avoid this defect, this invention incorporates a paint overflow prevention device 7. This device continuously transfers excess material from the edge of the scraper 3.4 to the center. Since the scraping principle of the scraper 3.4 ensures that regardless of the amount of material in the center (as long as it does not exceed the scraper height), the viscous coating can be smoothed. This reduces the amount of overflow at the edge of the scraper 3.4, thereby improving the overall quality of the scraping. In this embodiment, the suction head 7.1 is installed slightly higher than the lower edge of the scraper 3.4. When the height of the viscous material exceeds the height of the suction head 7.1, the negative pressure generated by the suction head 7.1 will transfer the material on the edge of the scraper 3.4 to the center.

[0038] Specifically, the texture compaction device 4 in this embodiment includes a hammer plate 4.1, which is driven to move up and down by a hammer plate drive cylinder 4.2. The hammer plate drive cylinder 4.2 is installed on the middle crossbeam of the frame 6.1. The bottom surface of the hammer plate 4.1 is provided with a texture shape, which includes a sawtooth shape, a wave shape, or a concave-convex shape.

[0039] The texture compaction device 4 is used to hammer out a certain shape of texture on the surface of the functional layer, such as hammering out a serrated texture, a wavy texture, or an uneven texture on the surface of the permeable concrete buffer layer. When the hammering plate 4.1 is not in operation, it is lifted to its highest position by the hammering plate drive cylinder 4.2. Accordingly, the paving device 1, the scraping device 3, etc. in this invention all have lifting functions to avoid interfering with the normal operation of other devices when not in operation.

[0040] Specifically, in this embodiment, both the front measurement sensor matrix 51 and the rear measurement sensor matrix 52 are composed of multiple laser rangefinders, which are mounted on the vehicle frame 6.1 via a sensor mounting plate 53. The front measurement sensor matrix 51 and the rear measurement sensor matrix 52 calculate the thickness of the viscous coating by measuring the height difference of the measured surface.

[0041] Both the front measurement sensor matrix 51 and the rear measurement sensor matrix 52 are composed of 5-10 laser rangefinders. The average value is obtained by measuring the distance of the measured surface by multiple laser rangefinders, thereby calculating the measurement height of the front and rear ends of the moving frame device 6 respectively. Finally, the thickness of the thick coating is estimated by the height difference.

[0042] Specifically, such as Figure 8As shown, the independent driving drive device 6.2 in this embodiment includes at least four sets, which are respectively used to install at the end or edge of the frame 6.1. The independent driving drive device 6.2 includes a track wheel assembly 6.2.1, which is connected to the driving drive motor 6.2.2 via a sprocket and a chain. The track wheel assembly 6.2.1 and the travel drive motor 6.2.2 are both mounted on the wheel support frame 6.2.3. The wheel support frame 6.2.3 is connected to the bushing via a rotating shaft. A steering hoop 6.2.4 is mounted on the outside of the rotating shaft. The steering hoop 6.2.4 is driven to steer by a steering cylinder 6.2.5. The steering cylinder 6.2.5 is rotatably mounted on the frame 6.1.

[0043] In this embodiment, four independent driving units 6.2 are respectively installed at the four corners of the frame 6.1, and the area in the middle of the four independent driving units 6.2 is the working area. This layout design enables this construction system to complete multiple paving tasks, that is, it can not only pave the crushed stone drainage layer, the permeable concrete buffer layer and the colored functional surface layer, but also spray the high-bonding transition layer and the fluorocarbon-silane composite protective layer.

[0044] Specifically, the system also includes a speed sensor and a main controller. The speed sensor is used to measure the travel speed of the mobile frame device 6. The speed sensor, the front measurement sensor matrix 51 and the rear measurement sensor matrix 52 are connected to the signal input terminal of the main controller. The output terminal of the main controller is connected to the drive cylinder or actuator of the paving device 1, the thick material spraying device 2, the scraping device 3 and the texture compaction device 4. The drive cylinder includes a horizontal plate lifting cylinder 3.1 and a scraper drive cylinder 3.3.

[0045] The main controller employs an industrial-grade programmable logic controller (PLC) system, specifically a Siemens S7-1500 series or equivalent controller. It can process data from the speed sensor and measurement sensor matrix in real time and output control signals to each actuator according to a preset algorithm. The laser rangefinder sensor is a high-precision diffuse reflection laser displacement sensor, specifically a Keyence IL-600 series, SICK DT50 series, or equivalent precision sensor.

[0046] In practical applications, the laser rangefinders are arranged in groups of 5-10 to form a front measurement sensor matrix 51 and a rear measurement sensor matrix 52. The spacing between adjacent sensors is 150-200mm. They are connected to the main controller via RS485 bus or EtherCAT bus to achieve synchronous sampling and data transmission.

[0047] The main controller calculates the difference ΔL=L1-L2 by comparing the average base surface height L1 measured by the front measurement sensor matrix 51 and the average coating surface height L2 measured by the rear measurement sensor matrix 52 in real time, and compares it with the target thickness D. When |ΔL-D|>1mm, the main controller outputs a signal to adjust the position of the horizontal plate lifting cylinder 3.1 to achieve closed-loop control of the coating thickness.

[0048] The basic principle of viscous material layer construction: Position the mobile frame device 6 to the construction starting point, lower the viscous material spraying device 2 to the working position, and adjust the working height according to the type of viscous material. Start the feed pump 2.4 and adjust the discharge speed of each spray head 2.1 through the flow control valve group to make the viscous material evenly sprayed on the base surface; At the same time, the scraping device 3 is started, and the main controller sets the travel speed V1 of the moving frame device 6 and the extension speed V2 of the scraper drive cylinder 3.3 according to the preset parameters, keeping V1=V2; When the scraper drive cylinder 3.3 extends to its maximum stroke, it quickly retracts to its initial position and then continues to extend at a speed of V2, forming a continuous intermittent scraping action. The thickness measurement system 5 operates in real time. The front measurement sensor matrix 51 measures the average height L1 of the front base surface, and the rear measurement sensor matrix 52 measures the average height L2 of the leveled surface. The main controller calculates the height difference ΔL = L1 - L2, and automatically adjusts the horizontal plate lifting cylinder 3.1 to change the height of the scraper 3.4 according to the set target thickness D, with a control accuracy of ±1mm; The paint overflow prevention device 7 works synchronously to prevent material from overflowing from the edge of the scraper 3.4.

[0049] Example 2: The construction method of the high-toughness permeable colored composite pavement construction system includes the following steps: S1. Construction of the foundation layer: The original soil compaction layer is constructed using a compactor. After spreading the crushed stone drainage layer and permeable concrete buffer layer using the paving device 1, the texture is treated using the textured compaction device 4 and cured for 18 hours. S2. Construction of high-bonding transition layer: Position the mobile frame device 6 to the construction starting point, lower the viscous material spraying device 2 to the working position, and adjust the working height according to the type of viscous material; at this time, the viscous material is a high-adhesion transition material.

[0050] Start the feed pump 2.4 and adjust the discharge speed of each spray head 2.1 through the flow control valve group to make the viscous material evenly sprayed on the base surface; At the same time, the scraping device 3 is started, and the main controller sets the travel speed V1 of the moving frame device 6 and the extension speed V2 of the scraper drive cylinder 3.3 according to the preset parameters, keeping V1=V2; When the scraper drive cylinder 3.3 extends to its maximum stroke, it quickly retracts to its initial position and then continues to extend at a speed of V2, forming a continuous intermittent scraping action. The thickness measurement system 5 operates in real time. The front measurement sensor matrix 51 measures the average height L1 of the front base surface, and the rear measurement sensor matrix 52 measures the average height L2 of the leveled surface. The main controller calculates the height difference ΔL = L1 - L2, and automatically adjusts the horizontal plate lifting cylinder 3.1 to change the height of the scraper 3.4 according to the set target thickness D, with a control accuracy of ±1mm; The paint overflow prevention device 7 works synchronously to prevent material from overflowing from the edge of the scraper 3.4.

[0051] Specifically, in this embodiment, the traveling speed of the mobile frame device 6 can be set to V1 = 0.6 m / s, and the extension speed of the scraper drive cylinder 3.3 can be set to V2 = 0.6 m / s; Adjust the working height of the nozzle 2.1 to 180mm and the working pressure to 15±1MPa; The amount of high-adhesion transition layer material should be controlled at 55±3 kg / m². The layer thickness is controlled within the range of 30±2mm by the thickness measurement system 5; After construction, cover with plastic wrap and allow to cure for 8 hours; S3, Colored Functional Surface Layer Construction: After completing the curing of the high-adhesion transition layer, raise the viscous material spraying device 2 and the scraping device 3 to the non-working position; Lower the height of paving device 1 and pave the colored functional surface layer; Perform necessary cleaning and expansion joint cutting; Allow to cure for 24 hours until fully hardened; S4, Fluorocarbon-silane composite protective layer construction: The fluorocarbon-silane composite protective material is evenly sprayed onto the colored functional surface layer using the thick material spraying device 2. In this embodiment, the travel speed of the mobile frame device 6 is set to V1 = 0.8 m / s, the working height of the spray head 2.1 is adjusted to 200-250 mm, the working pressure of the first spray is 18±1 MPa, and the working pressure of the second spray is 22±1 MPa; the amount of the first protective agent is controlled to be 0.20±0.02 kg / m², and after an interval of 4 hours, the second coat is sprayed perpendicular to the direction of the first coat, with an amount of 0.15±0.02 kg / m². S5. Maintenance and Acceptance: After the protective layer is completed, it will be cured in stages: for example, rain and dust protection for 24 hours, traffic restriction for 24-72 hours, and allow design load after 7 days. Conduct quality acceptance testing, including checking permeability, anti-slip performance, color consistency, and flatness; It will be put into use after passing the acceptance inspection.

[0052] The advantages of this method are as follows: First, when the moving frame device 6 moves forward, the scraper drive cylinder 3.3 extends synchronously. When V1 = V2, the scraper 3.4 remains stationary relative to the ground. After the scraper drive cylinder 3.3 extends to its maximum stroke, it quickly retracts once, achieving one scraping operation. Then, the scraper drive cylinder 3.3 extends again at a speed of V2. This results in a better scraping effect, as the scraper 3.4 continuously scrapes forward intermittently, rather than scraping once and then retracting once. Similarly, another advantage of this design is that if the scraper 3.4 is not driven by the scraper drive cylinder 3.3 but instead scrapes based on the travel speed of the moving frame device 6, the scraping speed will be slow, and the surface of the viscous material will be uneven.

[0053] Second, the front measuring sensor matrix 51 measures the average value L1, and the rear measuring sensor matrix 52 measures the average value L2. By using L1-L2=ΔL, the height of the scraper 3.4 can be adjusted at any time, thereby controlling the thickness D of the viscous material layer. This design can precisely control the scraping thickness.

[0054] Example 3: like Figure 9 As shown, a high-toughness permeable colored composite pavement structure includes, from bottom to top, a compacted original soil layer 8, a crushed stone drainage layer 9, a permeable concrete buffer layer 10, a high-bonding transition layer 11, a colored functional surface layer 12, and a fluorocarbon-silane composite protective layer 13. Specific parameters are as follows: The original soil compaction layer, with a compaction degree of ≥93%, is used to provide foundation bearing capacity and control settlement, serving as the supporting foundation for the entire pavement system. Specifically, an improved soil formula is adopted. When the original soil does not meet the requirements, lime, cement, and an appropriate amount of water are added in proportion to improve it, ensuring that the organic matter content is ≤5%, the liquid limit is ≤40%, and the plasticity index is ≤18.

[0055] The crushed stone drainage layer is used to quickly drain infiltrated water and prevent water accumulation, while also dispersing the load from the upper part of the structure. Specifically, it is composed of basalt crushed stone of a specific particle size and the porosity is controlled at 20-30%, which can ensure drainage performance and maintain structural stability.

[0056] The permeable concrete buffer layer is used to store and filter rainwater, and to buffer the impact of the upper load on the base layer. Specifically, it contains aggregates, cementitious materials, mineral admixtures and additives in a special ratio to form a structure with water storage and filtration functions. The porosity is controlled at 20-22% in summer construction and 22-24% in winter construction.

[0057] A high-adhesion transition layer is used to eliminate abrupt changes in interlayer modulus, enhance interlayer bonding strength, and improve overall toughness. Specifically, the interlayer bonding strength is enhanced by adding nano-active SiO2 and polymer modifiers to ensure that the bonding strength with the upper and lower layers is ≥0.8MPa.

[0058] The colored functional surface layer provides a decorative and aesthetically pleasing effect while also offering high wear resistance and anti-slip safety features. Specifically, it uses highly weather-resistant colored ceramic particles as aggregate, combined with white silicate cement and nano-silica, and the surface is treated to achieve an anti-slip safety effect.

[0059] The fluorocarbon-silane composite protective layer is used for UV protection and antifouling / anti-seepage, enhancing surface hardness while maintaining water permeability. Specifically, it is a protective agent with an organic-inorganic hybrid structure that effectively prevents UV erosion and oil penetration while maintaining water permeability.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
