Description
Technical Field
[0001] This invention relates to the field of asphalt pavement construction technology, and in particular to a vibration compaction construction process for asphalt pavement on highways. Background Technology
[0002] Vibratory compaction of asphalt pavement on highways is a crucial step in ensuring pavement quality and performance. This compaction is typically carried out using vibratory rollers. Vibratory rollers are engineering machines that utilize their own weight and vibration to compact various building and road construction materials. In highway construction, vibratory rollers are widely used because they are best suited for compacting various non-cohesive soils, crushed stone, crushed stone mixtures, and various types of asphalt concrete.
[0003] Compared to conventional rollers, existing vibratory rollers can more effectively improve the density and smoothness of road surfaces, thereby extending their service life and performance. Vibratory compaction ensures even distribution of materials, dispersing the load and increasing the road's load-bearing capacity, while reducing the risk of deformation or damage. It also reduces the rebound effect of asphalt surfaces on vehicle tires, resulting in a smoother surface and reduced bumps during driving. Furthermore, it helps reduce road porosity, improves drainage, and minimizes rainwater accumulation, mitigating traffic safety hazards caused by water accumulation. Vibratory rollers offer high construction efficiency, significantly shortening construction time, reducing costs, and improving project quality.
[0004] However, existing vibratory rollers typically have only one roller and an internal vibration mechanism. While compacting the asphalt pavement, the vibration effect needs to be improved. Furthermore, they lack the function of cleaning the outer wall of the roller. After prolonged use, a thick layer of dirt may accumulate on the outer wall of the roller, thus affecting the vibration compaction effect. Summary of the Invention

Vibratory compaction: Using a vibratory roller to compact asphalt concrete pavement, thereby improving the density and stability of the pavement; S4. Inspection and Repair: After the vibration compaction operation is completed, the asphalt concrete pavement is inspected and any non-compliant parts are repaired. S5.

Detailed Implementation
[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.
[0030] See Figure 1 A vibration compaction process for highway asphalt pavement includes the following steps: S1. Cleaning and Repair: First, clean the roadbed of the highway to be constructed, removing debris and accumulated dust; at the same time, repair potholes and damaged road surfaces. S2. Laying asphalt pavement: Laying asphalt concrete pavement on the highway subgrade to be constructed, ensuring uniform laying of asphalt concrete pavement. S3. Vibratory compaction: Using a vibratory roller to compact asphalt concrete pavement, thereby improving the density and stability of the pavement; S4. Inspection and Repair: After the vibration compaction operation is completed, the asphalt concrete pavement is inspected and any non-compliant parts are repaired. S5. Inspect and accept the construction quality to ensure that the compaction and smoothness of the road surface meet the requirements.
[0031] See Figure 2 and Figure 4The above step S3 is completed using a vibratory roller device, specifically including a vehicle body 1. A support column 2 is installed through the left end of the vehicle body 1. Triangular support components are set at both the front and rear ends of the support column 2. A roller unit 7 is set between the front and rear two triangular support components at the right position. A first-level vibration unit 5 is set between the front and rear two triangular support components at the left position. A second-level vibration unit 9 is set between the front and rear two triangular support components at the middle position. A lifting and cleaning unit 10 is set at the left end of the vehicle body 1 between the second-level vibration unit 9 and the roller unit 7.
[0032] See Figure 2 , Figure 3 and Figure 4 The triangular support assembly includes a first triangular support plate 3 and a second triangular support plate 4, which are provided on both the front and rear sides of the vehicle body 1. The opposite ends of the two first triangular support plates 3 are fixedly connected to the vehicle body 1.
[0033] See Figure 3 , Figure 4 , Figure 6 and Figure 7 The road compaction unit 7 includes circular mounting plates 71 installed on opposite ends of two first triangular support plates 3. The two circular mounting plates 71 are rotatably fitted with annular road compaction wheels 72. A circular seat 73 is installed in the middle of the inner wall of the annular road compaction wheel 72. A dual-axis motor 74 is installed at the rear end of the circular mounting plate 71 via a motor seat, and a rotary motor 78 is installed at the front end of the circular mounting plate 71 via a motor seat. The output shafts of the dual-axis motor 74 and the rotary motor 78 on opposite sides are rotatably passed through the corresponding circular mounting plates 71 and connected to a drive shaft 75. Both drive shafts 75 are simultaneously rotatably passed through adjacent first triangular support plates 3. The other ends of both drive shafts 75 are rotatably connected to the corresponding second triangular support plates 4. The other output shaft of the dual-axis motor 74 is connected to a first rotating shaft 76, which is installed through the middle of the circular seat 73. A transmission mechanism 77 is provided at the position of the drive shaft 75 between the corresponding first triangular support plate 3 and the second triangular support plate 4.
[0034] When vibratory compaction of asphalt concrete pavement is required, the operator first controls the vehicle body 1 to move to the target position and maintains a constant speed. At the same time, the dual-shaft motor 74 controls the first rotating shaft 76 to rotate. The first rotating shaft 76 drives the annular roller 72 to rotate through the circular seat 73, thereby compacting the asphalt concrete pavement. It should be noted that when the compaction unit 7 starts working, the speed of the vehicle body 1 must be controlled to be the same as the speed of the annular roller 72. The compaction unit 7 can drive the annular roller 72 to rotate at a constant speed, thereby achieving the effect of uniform compaction of the asphalt concrete pavement.
[0035] See Figure 2 , Figure 5 , Figure 6 and Figure 7 The secondary oscillation unit 9 includes a cylindrical roller 91 mounted on the opposite ends of two triangular support plates 3, with the roller 91 having a hollow cylindrical structure. A second rotating shaft 92 is mounted on the opposite ends of two triangular support plates 4, rotating through the two triangular support plates 3 and the cylindrical roller 91. Cams 93 are symmetrically mounted on the front and rear of the rotating shaft 92, and the two cams 93 roll in contact with an annular sleeve 94. The front and rear ends of the annular sleeve 94 are movably connected to the cylindrical roller 91. On the front and rear ends of the inner wall of the roller 91, and with the annular sleeve 94 eccentrically positioned corresponding to the second rotating shaft 92, the front and rear ends of the inner wall of the cylindrical roller 91 are jointly equipped with annular support plates 95. Multiple sets of vibration components are evenly arranged on the outer wall of the annular sleeve 94. Each set of vibration components consists of multiple slide rods 96 evenly distributed in a circle. Multiple slide rods 96 slide through the annular support plate 95, and an arc-shaped impact plate 97 is installed at the end of each slide rod 96 away from the annular sleeve 94. The outer wall of the arc-shaped impact plate 97 movably contacts the inner wall of the cylindrical roller 91.
[0036] See Figures 3-5 The transmission mechanism 77 includes two large sprockets 771 that are rotatably mounted on the opposite ends of the two first triangular support plates 3 corresponding to the positions of the transmission shafts 75. The two large sprockets 771 are mounted on the corresponding transmission shafts 75. Small sprockets 773 are rotatably mounted on the opposite ends of the two first triangular support plates 3 corresponding to the positions of the second rotating shafts 92. The two small sprockets 773 are mounted on the second rotating shafts 92. The large sprockets 771 and the small sprockets 773 on the same side are together fitted with a chain 775.
[0037] When the first rotating shaft 76 is controlled to rotate by the dual-axis motor 74, the dual-axis motor 74 and the rotary motor 78 respectively drive the corresponding transmission shaft 75 to rotate. The two transmission shafts 75 are respectively driven by the corresponding large sprocket 771, small sprocket 773 and chain 775, which together drive the second rotating shaft 92 to rotate. The second rotating shaft 92 drives the annular sleeve 94 to rotate eccentrically through the two cams 93. The annular sleeve 94 drives the corresponding multiple arc-shaped impact plates 97 to rotate eccentrically through multiple slide rods 96. During the rotation, the outer walls of multiple arc-shaped impact plates 97 will sequentially impact the inner wall of the cylindrical roller 91. It should be noted that, under the combined action of the vehicle body 1 and the roller unit 7, the cylindrical roller 91 will rotate at a constant speed following the annular roller 72. The roller unit 7, in cooperation with the secondary vibration unit 9, can drive the arc-shaped impact plates 97 to sequentially impact the inner wall of the cylindrical roller 91 through the transmission mechanism 77, thereby achieving the effect of uniformly compacting and vibrating the asphalt concrete pavement through the cylindrical roller 91.
[0038] See Figures 3-5 The adjacent first triangular support plate 3 and second triangular support plate 4 are connected by a connecting column 8 on their left sides. The two adjacent first triangular support plates 3 and second triangular support plates 4 on the front and rear sides are fitted with mudguards 6. The two second triangular support plates 4 on the front and rear sides are rotatably mounted with a drive gear 772 at the end near the large sprocket 771. The two drive gears 772 on the front and rear sides are mounted on the corresponding drive shafts 75. The two second triangular support plates 4 on the front and rear sides are rotatably mounted with an eccentric wheel 774 at the end near the small sprocket 773. The two eccentric wheels 774 on the front and rear sides are mounted on the second rotating shaft 92.
[0039] See Figure 2 , Figure 4 , Figure 5 and Figure 7 The first-stage oscillation unit 5 includes a semi-circular head connecting plate 51 that is slidably installed at the opposite ends of two first-stage triangular support plates 3. A road roller 52 is installed at the lower end of the semi-circular head connecting plate 51. Waist-shaped guide holes 53 are opened at the corresponding positions of the first-stage triangular support plates 3 and the second-stage triangular support plates 4 on both the front and rear sides of the semi-circular head connecting plate 51. A support cylinder 54 is installed through the upper end of the semi-circular head connecting plate 51. The front and rear ends of the support cylinder 54 are slidably connected to the corresponding two waist-shaped guide holes 53. An extension cylinder 55 is installed at the lower end of the part of the support cylinder 54 located between the corresponding first-stage triangular support plate 3 and the second-stage triangular support plate 4. A support slider 56 is installed at the lower end of the extension cylinder 55. The support slider 56 slides against the corresponding second-stage triangular support plate 4, and the lower end of the support slider 56 is connected to the mudguard 6 through a spring buffer 57.
[0040] See Figure 2 , Figure 4 , Figure 5and Figure 7 The first-stage oscillation unit 5 also includes an annular collar 58 rotatably sleeved on the outer wall of the eccentric wheel 774. A vertical connecting rod 59 is installed on the upper end of the annular collar 58. The first triangular support plate 3 and the second triangular support plate 4 on the front and rear sides are provided with waist-shaped limiting through holes 60 corresponding to the positions of the vertical connecting rod 59. A connecting slide bar 61 is installed through the upper end of the vertical connecting rod 59. The front and rear ends of the connecting slide bar 61 are slidably connected in the two corresponding waist-shaped limiting through holes 60. An arc-shaped connecting rod 62 is rotatably sleeved on the end of the connecting slide bar 61 away from the vertical connecting rod 59. The other end of the arc-shaped connecting rod 62 is hinged to the support slider 56. A trapezoidal support plate 63 is installed at the bottom end of the inner wall of the mudguard 6 corresponding to the position of the arc-shaped connecting rod 62. The upper end of the trapezoidal support plate 63 is rounded.
[0041] When the second rotating shaft 92 rotates, it drives the annular collar 58 to rotate eccentrically via the eccentric wheel 774. Under the limiting action of the waist-shaped limiting through hole 60, the annular collar 58 drives the connecting slide bar 61 to reciprocate up and down along the waist-shaped limiting through hole 60 via the vertical connecting rod 59. Under the support of the trapezoidal support plate 63 and the limiting action of the waist-shaped guide through hole 53, the connecting slide bar 61 drives the support slider 56 to reciprocate up and down via the arc-shaped connecting rod 62. The support slider 56 drives the support cylinder 54 to reciprocate up and down via the extended cylinder 55. The support cylinder 54 drives the road roller 52 to reciprocate up and down via the semi-circular head connecting plate 51. During this period, the spring buffer 57 can buffer the support slider 56. The secondary vibration unit 9 cooperates with the primary vibration unit 5 to drive the road roller 52 to reciprocate up and down without increasing the drive, thereby achieving a uniform vibration effect on the asphalt concrete pavement and effectively improving the vibration effect on the asphalt concrete pavement.
[0042] See Figure 2 , Figure 3 and Figure 5 The lifting cleaning unit 10 includes waist-shaped through holes 101 on both the first and second triangular support plates 3 and 4 on the front and rear sides. The waist-shaped through holes 101 are located on the upper side between the annular roller 72 and the cylindrical roller 91. A connecting shaft 102 is slidably installed on multiple waist-shaped through holes 101. The front and rear ends of the connecting shaft 102 that extend out of the waist-shaped through holes 101 are rotatably fitted with extension seats 103. A driven gear 104 is installed on both the front and rear sides of the connecting shaft 102. The driven gear 104 is rotatably connected to the corresponding second triangular support plate 4. A transmission gear 105 is installed on the end of the second triangular support plate 4 near the driven gear 104. The transmission gear 105 on the same side meshes with the driving gear 772.
[0043] See Figure 2 , Figure 3 , Figure 5 and Figure 7 A brush cylinder 106 is sleeved between the front and rear two No. 1 triangular support plates 3. A scraper 107 is installed between the front and rear two No. 1 triangular support plates 3 and between the annular roller 72 and the cylindrical roller 91. A material leakage hole 108 is opened in the middle of the scraper 107. A rectangular support plate 109 is installed on the left end of the vehicle body 1. Electric telescopic rods 110 are installed at both the front and rear ends of the rectangular support plate 109. The telescopic ends of the electric telescopic rods 110 on the front and rear sides are respectively connected to the corresponding extension seats 103. Multiple interconnected high-pressure nozzles 111 are evenly installed through the lower end of the rectangular support plate 109.
[0044] After the vibration compaction of the asphalt concrete pavement is completed, the dual-shaft motor 74 stops working, and the vehicle body 1 is manually moved to a suitable location for cleaning. The two electric telescopic rods 110 at the front and rear drive the extension seats 103 downwards. The two extension seats 103 together drive the connecting shaft 102 downwards until it is at the lowest point of the oblong through-hole 101. At this point, the connecting shaft 102 drives the brush cylinder 106 downwards, and the brush bristles contact the outer walls of the annular roller 72 and the cylindrical roller 91. The connecting shaft 102 also drives the driven gear 104 downwards. Since the connecting shaft 102 can drive the driven gear 104 to rotate freely, the driven gear 104 will automatically adjust its position after contacting the transmission gear 105, thus achieving the meshing effect between the driven gear 104 and the transmission gear 105. Then, the dual-shaft motor 74 and the rotary motor 78 respectively... The corresponding drive shaft 75 is driven to rotate. The two drive shafts 75 are driven by the active gear 772, the transmission gear 105 and the passive gear 104, which in turn drive the connecting shaft 102 to rotate. The connecting shaft 102 drives the brush cylinder 106 to rotate. At this time, the brush cylinder 106 is sprayed with water through multiple high-pressure nozzles 111 connected to an external water tank, thereby cleaning the outer walls of the annular roller 72 and the cylindrical roller 91. The sludge washed off is discharged through the material leakage hole 108. It should be noted that during the vibration compaction of the asphalt concrete pavement, if the mud and dirt adhering to the outer walls of the annular roller 72 and the cylindrical roller 91 are too thick, they will be scraped off by the scraper 107. The scraped mud and dirt are also discharged through the material leakage hole 108. When the cleaning of the outer walls of the annular roller 72 and the cylindrical roller 91 is completed, the dual-shaft motor 74 stops working.
[0045] Repeating the above operations allows for repeated vibration compaction of the asphalt concrete pavement. The roller unit 7, secondary vibration unit 9, primary vibration unit 5, and lifting and cleaning unit 10 work together, using a single drive to simultaneously achieve primary vibration, secondary vibration, primary compaction, secondary compaction, and cleaning. This effectively improves the compaction and vibration effect on the asphalt concrete pavement, reduces energy consumption, and allows for timely cleaning of the outer walls of the annular roller 72 and the cylindrical roller 91, preventing dirt residue from affecting the normal compaction and vibration effect of the equipment.
