Abstract
Description
Technical Field
[0001] This application relates to the field of road construction, and in particular to a continuous paving device and paving method for road lime-soil. Background Technology
[0002] The construction of lime-soil base courses for highways is crucial to the service life, compressive strength, and stability of highways. The road mixing method is widely used due to its advantages such as simple mixing and faster progress.
[0003] In the related technology, Chinese patent CN219410487U discloses a paving device, including a mounting plate, a material bin fixedly connected to the upper end of the mounting plate, a guide groove opened on the upper end surface of the mounting plate, a paving mechanism slidably connected in the guide groove, the paving mechanism including a guide column slidably connected in the guide groove, a paving plate fixedly connected to the lower end of the guide column, a spring fixedly connected between the paving plate and the mounting plate, a first rotating seat fixedly connected to the lower end of the mounting plate, a connecting rod rotatably connected in the first rotating seat, a cam fixedly connected to the circumferential surface of the connecting rod, and the cam fitting against the paving plate.
[0004] During operation, the material is first poured into the material bin. Then, by opening the sliding stop plate inside the material bin, the material is discharged downwards from the material bin through the movement of the mounting plate. At this point, the material is laid on the road. As the mounting plate moves forward, the paving plate moves to the position where the material was just discharged. Then, by rotating the connecting rod, the connecting rod drives the cam to rotate. Then, the tension of the spring pulls the paving plate upwards, thereby achieving the effect of shaking the paving plate to beat the discharged material, ultimately completing the paving.
[0005] However, the height of the material silo opening from the ground is movable, while the amount of material falling from the silo to the ground is fixed. This makes it impossible to precisely control the thickness of the material spread on the ground according to actual needs. In other words, the material that has fallen to the ground needs to be spread again to meet the actual required thickness, which is inconvenient to operate and therefore needs to be improved. Summary of the Invention
[0006] In order to address the problem that it is impossible to control the thickness of the material falling to the ground, it is necessary to further flatten it to a specified thickness, which leads to operational inconvenience, this application provides a continuous road lime-soil paving device and paving method.
[0007] Firstly, the continuous road lime-soil paving device provided in this application adopts the following technical solution:
[0008] A continuous road lime-soil paving device includes:
[0009] A mobile vehicle body, wherein a through hole is provided on the mobile vehicle body, and rollers are rotatably connected to the bottom of the mobile vehicle body;
[0010] A storage bin is placed on the mobile vehicle body. The storage bin includes a vertically extending mounting frame and a mounting plate placed inside the mounting frame. The mounting frame is fixed to the mobile vehicle body, and the bottom end of the mounting frame is aligned with the through hole. The circumferential sidewall of the mounting plate is fitted with the inner wall of the mounting frame. A discharge port communicating with the through hole is provided through the mounting plate. An adjustment component is provided on the mounting frame, and the mounting plate is connected to the adjustment component. The adjustment component is used to drive the mounting plate to move up and down.
[0011] By adopting the above technical solution, during operation, the rollers rotate, causing the mobile vehicle to move to the construction area and align the through hole with the paving position. Then, according to the required paving height, the height of the mounting plate is adjusted using the adjustment component, thereby changing the height of the discharge port from the ground so that the coverage is equal to the required paving height. Then, the lime is poured into the storage box, and the mobile vehicle is driven to move. The lime in the storage box is evenly discharged from the discharge port and falls to the ground through the through hole. At this time, the height of the lime falling to the ground is equal to the height of the discharge port from the ground, thereby precisely controlling the paving thickness and achieving high-precision lime paving. There is no need to further adjust the paving of the lime that falls to the ground, making the operation convenient.
[0012] Optionally, the adjustment component includes:
[0013] The mounting box is fixed to the inner wall of the mounting frame, and the mounting box is located above the mounting plate;
[0014] An adjusting rod is vertically mounted in the mounting frame, and the top end of the adjusting rod is rotatably connected to the mounting box. The adjusting rod passes through the mounting plate and is threadedly connected to the mounting plate.
[0015] The transmission bevel gear is rotatably connected in the mounting box and is coaxially fixed with the top end of the adjusting rod;
[0016] A rotating bevel gear is rotatably connected in the mounting box, and the rotating bevel gear meshes with the transmission bevel gear;
[0017] A handle is rotatably connected to the mounting frame, with one end of the handle passing through the mounting frame and extending into the mounting box, where it is fixed coaxially with the rotating bevel gear.
[0018] By adopting the above technical solution, turning the handle causes the rotating bevel gear to rotate, which in turn drives the transmission bevel gear to rotate, thereby causing the adjusting rod to rotate around the central axis of the adjusting rod. Because the mounting plate is threadedly connected to the adjusting rod, and the mounting plate is restricted by the mounting frame, it cannot rotate around the central axis of the adjusting rod. This causes the mounting plate to move up and down along the length of the adjusting rod, thereby allowing the discharge port to change its height according to the required paving thickness.
[0019] Optionally, the mounting frame includes a screening component, the screening component comprising:
[0020] A plurality of screening plates are arranged at intervals along the length of the mounting frame. The screening plates are slidably connected to the mounting frame. The mounting frame is provided with a moving component for driving the screening plates to move along the width of the mounting frame.
[0021] Several screening rods are fixed on the side wall of the screening plate. The length of the screening rod is equal to the distance between adjacent screening plates. The screening rods are arranged at intervals along the width direction of the mounting frame, and the screening rods on the side wall of adjacent screening plates are arranged vertically.
[0022] By adopting the above technical solution, when lime is poured into the storage box, smaller lime particles will fall below the screening plate through the gap between the screening plate and the inner wall of the mounting frame, as well as the gap between adjacent screening rods. The remaining lime is blocked on the screening plate and screening rods. Then, the moving component drives several screening plates to move back and forth along the width of the mounting frame. At the same time, several screening rods also move continuously, causing the screening rods on adjacent screening plates to move closer or further away in the horizontal direction. This cuts and crushes the lime that falls between adjacent screening plates, preventing lumps of lime from entering below the screening plate. At the same time, the movement of the screening plate also moves the lime, thus loosening the lime that falls on the screening plate and screening rods, making it easier for the lime to fall below the screening plate.
[0023] Optionally, the inner wall of the mounting frame is provided with a plurality of mounting grooves, and one side of each screening plate is correspondingly fitted into a mounting groove, and the screening plate can move in the mounting groove along the width direction of the mounting frame.
[0024] By adopting the above technical solution, when the moving component drives the screening plate to move, the inner wall of the mounting groove abuts against the side wall of the screening plate, which plays a role in restricting and guiding the screening plate, so that the screening plate can only move along the width direction of the mounting frame, and it is not easy to deviate, thus increasing the stability of the screening plate movement.
[0025] Optionally, the moving component includes:
[0026] A movable plate is slidably connected to the mounting frame. The movable plate can move along the length direction of the mounting frame. A movable hole is opened through the screening plate. The movable plate is inserted into the movable hole. A wavy movable groove is opened on the movable plate along the length direction of the movable plate.
[0027] A plurality of movable blocks, each of which corresponds to a screening plate, are fixed on the inner wall of a movable hole, are inserted into a movable groove, and are able to move relative to each other in the movable groove.
[0028] By adopting the above technical solution, the moving plate is driven to move, the inner wall of the moving groove abuts against the moving block, and the mounting groove restricts the screening plate, so that the moving block cannot move with the moving plate, thereby causing the moving block to slide on the inner wall of the moving groove, that is, the moving block moves along the trajectory of the moving groove, so that the moving block moves in a wave-like manner in the horizontal direction, thereby realizing the movement of the screening plate in the width direction of the mounting frame.
[0029] Optionally, the mounting frame is provided with a drive component that moves in conjunction with the drive moving plate, the drive component including:
[0030] A rotating disc is rotatably connected to the side wall of the mounting frame. The rotating disc is connected to a roller via a transmission belt. The rotation of the roller drives the transmission belt to rotate the rotating disc.
[0031] A drive rod, one end of which is hinged to a rotating disk and the other end of which is hinged to a movable plate, rotates to drive the drive rod to move, thereby driving the movable plate to move along the length of the mounting frame.
[0032] By adopting the above technical solution, when the mobile vehicle moves, the rollers rotate, and through the transmission belt, the rotating disk rotates, thereby driving one end of the drive rod to rotate around the central axis of the rotating disk. This changes the distance between the moving plate and the connection point between the drive rod and the rotating disk. The other end of the drive rod is connected to the moving plate, so that the vertical height of the other end of the drive rod remains unchanged. This causes the end of the drive rod to rotate at the ends of both the rotating disk and the moving plate, thus changing the angle between the drive rod and the horizontal line to satisfy the distance between the moving plate and the connection point between the drive rod and the rotating disk. As the drive rod moves, it also drives the moving plate to move closer to or further away from the rotating disk, realizing the movement of the moving plate along the length of the mounting frame.
[0033] Optionally, the mounting frame is provided with a plurality of flipping rods, one end of which is fixed to the center of the rotating disk via a rotating shaft, and the plurality of flipping rods are arranged radially with the center of the rotating disk as the center.
[0034] By adopting the above technical solution, when the mobile vehicle moves, the rollers drive the rotating disc via the transmission belt, simultaneously rotating several tilting rods. This agitates the lime below the screening plate, preventing it from piling up in one place and allowing it to be spread as evenly as possible on the mounting plate for easy discharge from the outlet. It also prevents the lime from accumulating and clumping on the mounting plate, which would affect the paving accuracy.
[0035] Optionally, the top of the mounting frame is provided with a cover plate for sealing the top opening of the mounting frame, and insertion holes are provided on both opposite side walls of the mounting frame, and the cover plate can be inserted into the insertion holes.
[0036] By adopting the above technical solution, after the lime is poured into the storage box, the cover plate is inserted from the insertion hole on one side and moved horizontally to the insertion hole on the other side of the mounting frame, thereby blocking the top opening of the mounting frame. When the screening plate screens the lime and moves the lime, it is easy to cause small lime particles to fly up. The cover plate prevents the lime from moving out of the storage box from the top opening of the mounting frame, thus reducing the pollution to the construction environment.
[0037] Optionally, the top wall of the mounting plate is provided with a guide surface, and the end of the guide surface near the discharge port is inclined downward.
[0038] By adopting the above technical solution, when lime falls into the storage box, the lime accumulates on the mounting plate, and the guide surface plays a guiding role, causing the lime to move along the guide surface towards the discharge port, thus making it easier for the lime to be discharged from the storage box from the discharge port.
[0039] Secondly, the paving method of the continuous road lime-soil paving device provided in this application adopts the following technical solution:
[0040] S1. Level the underlying layer, remove excess debris, and moisten it with water as needed;
[0041] S2. Using a total station, the outer boundary of the construction area is measured and laid out according to the design drawings. Based on the elevation control points, the stakes are set out in the construction area.
[0042] S3. Next, pour the lime into the storage box, turn the handle, and use the adjusting rod to adjust the height of the mounting plate, thereby adjusting the height of the discharge port from the ground. Then drive the mobile vehicle to move, moving the storage box in the construction area. The lime in the storage box is evenly discharged into the construction area through the discharge port to achieve lime spreading.
[0043] S4. After the lime is laid, measure the thickness of the paving on site. If it meets the requirements, carry out lime-soil mixing operation and drive the road mixer into the construction site to mix. Use a grader to roughly level the lime-soil from the inside to the outside, scrape up any obvious unevenness, and use a toothed rake to loosen the low-lying areas of the wheel tracks. Add lime-soil to level the surface.
[0044] S5. After the rough leveling construction is completed, the mixed lime soil is left to stand. After the standing is completed, a tire roller is used to quickly and statically compact the entire width once. Then, a grader is used to perform fine leveling according to the measured elevation control points.
[0045] S6. Finally, the road roller travels to the construction site and compacts the construction area to complete the laying of the lime-soil layer.
[0046] By adopting the above technical solution, before the construction of the lime-soil base course, the various indicators of the underlying layer are inspected to ensure they meet the specifications and design requirements. The underlying layer is then leveled, excess debris is removed, and it is appropriately moistened with water. Next, a total station is used to measure and mark the outer edge of the lime-soil construction area according to the design drawings. Based on elevation control points, stakes are set up within the construction area. Then, the mobile vehicle is driven into the construction site and parked in a sheltered location near the outer edge of the construction area. The handle is turned to drive the adjusting rod, adjusting the height of the mounting plate and controlling the distance from the discharge port to the ground according to the required lime thickness. The mobile vehicle is then driven to move the storage tank within the construction area. The lime in the storage tank is evenly discharged into the construction area through the discharge port, achieving lime spreading.
[0047] After the lime paving is completed, the paving thickness is measured on site. If it meets the requirements, lime-soil mixing is carried out. The road mixer is brought into the construction site to mix the lime and soil, starting from the middle of the road starting point and mixing twice. After mixing, the mixing quality is inspected. Only after passing the inspection can a grader be used to roughly level the lime-soil from the inside out, scraping away any obvious unevenness. The toothed rake is used to loosen the low-lying areas of the wheel tracks, and lime-soil is added for leveling. After shaping, the road slope and camber are inspected. After the rough leveling is completed, the mixed lime-soil needs to be left to stand for two days and nights. After that, a pneumatic tire roller is used to quickly compact the entire width once, and then a grader is used to perform fine leveling according to the measured elevation control points.
[0048] After the paving and leveling meet the design and specification requirements, check whether the moisture content is controlled within ±2% of the optimum moisture content, and then carry out compaction operations. First, use a vibratory roller to compact 5 times, and then use a three-drum roller for static compaction 2 times.
[0049] In summary, this application includes at least one of the following beneficial effects:
[0050] 1. During operation, the rollers rotate, moving the mobile vehicle to the construction area and aligning the through hole with the paving position. Then, according to the required paving height, the height of the mounting plate is adjusted using the adjustment component, thereby changing the height from the discharge port to the ground, so that the coverage is equal to the required paving height. Then, the lime is poured into the storage box, and the mobile vehicle is driven to move. The lime in the storage box is evenly discharged from the discharge port and falls to the ground through the through hole. At this time, the height of the lime falling to the ground is equal to the height of the discharge port from the ground, thereby precisely controlling the paving thickness and achieving high-precision lime paving.
[0051] 2. After the lime is poured into the storage bin, smaller lime particles will fall below the screen plate through the gap between the screen plate and the inner wall of the mounting frame, as well as the gap between adjacent screen rods. The remaining lime is blocked on the screen plate and screen rods. Then, the moving component drives several screen plates to move back and forth along the width of the mounting frame. At the same time, several screen rods also move continuously, causing the screen rods on adjacent screen plates to move closer or further away in the horizontal direction. This cuts and crushes the lime that falls between adjacent screen plates, preventing lumps of lime from entering below the screen plate. The movement of the screen plate also moves the lime, thus loosening the lime that falls on the screen plate and screen rods, making it easier for the lime to fall below the screen plate.

[0057] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0058] This application discloses a continuous road lime-soil paving device. (Refer to...) Figure 1 and Figure 2 The continuous paving device for lime-soil road includes a mobile vehicle body 10. Several rollers 11 are rotatably connected to the bottom of the mobile vehicle body 10, and the rotation of the rollers 11 drives the mobile vehicle body 10 to move. A through hole 12 communicating with the ground is provided through the mobile vehicle body 10. A storage box 20 is fixed on the mobile vehicle body 10. The storage box 20 includes a vertically extending mounting frame 21 and a horizontally placed mounting plate 22 within the mounting frame 21. The mounting frame 21 is inserted into the through hole 12 and fixedly connected to the inner wall of the through hole 12. The circumferential sidewall of the mounting plate 22 abuts against the inner wall of the mounting frame 21. A discharge port 222 is provided through the mounting plate 22, and the discharge port 222 is arranged along the width direction of the mounting frame 21. A guide surface 221 is cut on the top wall of the mounting plate 22, and the side of the guide surface 221 communicating with the discharge port 222 slopes downwards. The mounting frame 21 has two holes 211 on opposite sides. The holes 211 are located at the top of the mounting frame 21. A cover plate 23 is inserted into the holes 211. When the cover plate 23 is inserted into the two holes 211, it blocks the top opening of the mounting frame 21.
[0059] After the lime is poured into the storage bin 20, the cover plate 23 is inserted through the insertion hole 211 on one side and moved horizontally to the insertion hole 211 on the other side of the mounting frame 21, thereby sealing the top opening of the mounting frame 21 and preventing small lime particles from flying up and moving out of the storage bin 20 from the top of the mounting frame 21, thus suppressing dust. The lime entering the storage bin 20 accumulates on the mounting plate 22, and the guide surface 221 acts as a guide, causing the lime to move along the guide surface 221 towards the discharge port 222, making it easier for the lime to be discharged from the storage bin 20 from the discharge port 222.
[0060] Reference Figure 1 and Figure 3To control the thickness of the lime paving and achieve precise paving, an adjustment component 30 is provided on the mounting frame 21. The adjustment component 30 is connected to the mounting plate 22. The adjustment component 30 includes a mounting box 31, an adjustment rod 32, and a handle 35. The mounting box 31 is fixed to the inner wall of the mounting frame 21. The adjustment rod 32 is inserted into the mounting frame 21. The top end of the adjustment rod 32 is rotatably connected to the mounting box 31. A transmission bevel gear 33 is coaxially fixed to the top end of the adjustment rod 32. The transmission bevel gear 33 is rotatably connected to the inner wall of the mounting box 31. The transmission bevel gear 33 meshes with a rotating bevel gear 34. The rotating bevel gear 34 is rotatably connected to the inner wall of the mounting box 31. The handle 35 is coaxially fixed to the rotating bevel gear 34. The end of the handle 35 away from the rotating bevel gear 34 extends out of the mounting frame 21.
[0061] Manually turning handle 35 causes the rotating bevel gear 34 to rotate, driving the transmission bevel gear 33 to rotate. This, in turn, causes the adjusting rod 32 to rotate around its central axis. Because the mounting plate 22 is threadedly connected to the adjusting rod 32, and the mounting plate 22 is restricted by the mounting frame 21, it cannot rotate around the central axis of the adjusting rod 32. This causes the mounting plate 22 to move up and down along the length of the adjusting rod 32, changing the height of the discharge port 222 from the ground. This ensures that the coverage is equal to the required paving height. At this point, the height of the lime falling from the discharge port 222 to the ground is equal to the height of the discharge port 222 from the ground, thus precisely controlling the paving thickness and achieving high-precision lime paving.
[0062] Reference Figure 2 and Figure 4 To prevent lumpy lime from reaching the mounting plate 22 and being discharged to the ground from the discharge port 222, a screening assembly 40 is provided in the mounting frame 21, and an adjusting assembly 30 is located below the screening assembly 40. The screening assembly 40 includes several screening plates 41 and several screening rods 42. The screening plates 41 are arranged at intervals along the length of the mounting frame 21. Several mounting grooves 212 are provided on the inner wall of the mounting frame 21. One side of each screening plate 41 is correspondingly fitted into a mounting groove 212. A moving drive is provided on the mounting frame 21 to drive the screening plates 41 to move along the width of the mounting frame 21 in the mounting grooves 212.
[0063] Reference Figure 2 and Figure 4 Each screening plate 41 has several screening rods 42 fixed on its side wall. The screening rods 42 are arranged at intervals along the width direction of the mounting frame 21. The screening rods 42 on each screening plate 41 are on the same horizontal plane, while the screening rods 42 on the side walls of adjacent screening plates 41 are arranged vertically.
[0064] When lime is poured into the storage bin 20, smaller lime particles fall through the gap between the screening plate 41 and the inner wall of the mounting frame 21, as well as the gap between adjacent screening rods 42, to the bottom of the screening plate 41. The remaining lime is blocked on the screening plate 41 and the screening rods 42. Then, the moving component 50 drives several screening plates 41 to move back and forth in the mounting groove 212 along the width direction of the mounting frame 21. At the same time, several screening rods 42 also move continuously, causing the screening rods 42 on adjacent screening plates 41 to move closer or further away in the horizontal direction. This cuts and crushes the lime that falls between adjacent screening plates 41, preventing lumps of lime from entering the bottom of the screening plate 41. The movement of the screening plate 41 also moves the lime, thus loosening the lime that falls on the screening plate 41 and the screening rods 42, making it easier for the lime to fall to the bottom of the screening plate 41.
[0065] Reference Figure 1 and Figure 4 The moving component 50 includes a moving plate 51 and several moving blocks 52. The moving plate 51 penetrates both side walls of the mounting frame 21 along its length and is movable along the length of the mounting frame 21. A moving hole 411 is provided through the screening plate 41, and the moving plate 51 is inserted into the moving hole 411 and can move within the moving hole 411. Each moving block 52 corresponds to one screening plate 41 and is fixed to the inner bottom wall of the moving hole 411. A wavy moving groove 511 is provided on the bottom wall of the moving plate 51, and the moving block 52 is adapted to be inserted into the moving groove 511 and can move within the moving groove 511.
[0066] The moving plate 51 is driven to move, and the inner wall of the moving groove 511 abuts against the moving block 52. The mounting groove 212 restricts the screening plate 41, preventing the moving block 52 from moving with the moving plate 51. This causes the moving block 52 to slide on the inner wall of the moving groove 511, that is, the moving block 52 moves along the trajectory of the moving groove 511, so that the moving block 52 moves in a wave-like manner in the horizontal direction, thereby realizing the movement of the screening plate 41 in the width direction of the mounting frame 21.
[0067] Reference Figure 1 and Figure 3To ensure that the movable plate 51 moves synchronously with the movable vehicle body 10, a drive assembly 60 is provided on the side wall of the mounting frame 21. The drive assembly 60 includes a rotating disk 61 and a drive rod 62. The rotating disk 61 is rotatably connected to the outer side wall of the mounting frame 21 via a rotating shaft 80. The rotating disk 61 is connected to the roller 11 via a transmission belt 63. The transmission belt 63 includes a driving wheel 631, a driven wheel 632, and a belt 633. The driving wheel 631 is coaxially fixed to the roller 11, and the driven wheel 632 is coaxially fixed to the rotating shaft 80. The belt 633 is sleeved on the driving wheel 631 and the driven wheel 632. One end of the drive rod 62 is hinged to the rotating disk 61, and the other end is hinged to a transmission rod 621. The transmission rod 621 is fixed to the end of the movable plate 51.
[0068] When the moving vehicle body 10 moves, the roller 11 rotates, which, through the transmission belt 63, causes the rotating disk 61 to rotate. This causes one end of the drive rod 62 to rotate about the central axis of the rotating disk 61, changing the distance between the moving plate 51 and the connection point between the drive rod 62 and the rotating disk 61. The other end of the drive rod 62 is connected to the moving plate 51, so that the vertical height of the other end of the drive rod 62 remains unchanged. This causes the end of the drive rod 62 to rotate at the ends of the rotating disk 61 and the moving plate 51, respectively, thus changing the angle between the drive rod 62 and the horizontal line to satisfy the distance between the moving plate 51 and the connection point between the drive rod 62 and the rotating disk 61. As the drive rod 62 moves, it also causes the moving plate 51 to move closer to or further away from the rotating disk 61, so that the moving plate 51 moves synchronously with the moving vehicle body 10.
[0069] Reference Figure 3 and Figure 4 To prevent the lime falling below the screening plate 41 from accumulating and clumping, one end of the rotating shaft 80 extends into the mounting frame 21. Several flipping rods 70 are fixed on the rotating shaft 80, and the flipping rods 70 are arranged radially with the central axis of the rotating shaft 80 as the center.
[0070] As the mobile vehicle 10 moves, the rollers 11 drive the rotating disc 61 to rotate via the transmission belt 63, simultaneously rotating several tilting rods 70. This agitates the lime below the screening plate 41, preventing it from piling up in one place and allowing it to be spread as evenly as possible on the mounting plate 22 for easy discharge from the outlet 222. It also prevents the lime from accumulating and clumping on the mounting plate 22, which would affect the paving accuracy.
[0071] The implementation principle of the continuous lime-soil paving device of this application embodiment is as follows: During operation, the roller 11 rotates, causing the moving vehicle 10 to move to the construction area, so that the through hole 12 is aligned with the paving position. Then, according to the required paving height, the handle 35 is manually turned, causing the rotating bevel gear 34 to rotate, driving the transmission bevel gear 33 to rotate, thereby driving the adjusting rod 32 to rotate around the central axis of the adjusting rod 32, so that the mounting plate 22 moves up and down along the length direction of the adjusting rod 32 to adjust the height of the mounting plate 22, thereby changing the height of the discharge port 222 from the ground, so that the coverage is equal to the required paving height. Then, the lime is poured into the storage box 20, and the moving vehicle 10 is driven to move. The lime in the storage box 20 is evenly discharged from the discharge port 222 and falls to the ground through the through hole 12. At this time, the height of the lime falling to the ground is equal to the height of the discharge port 222 from the ground, thereby accurately controlling the paving thickness and realizing high-precision lime paving.
[0072] This application also discloses a paving method for a continuous road lime-soil paving device.

[0074] S2. Using a total station, the outer boundary of the construction area is measured and laid out according to the design drawings. Based on the elevation control points, the stakes are set out in the construction area.
[0075] S3. Next, pour the lime into the storage box 20, turn the handle 35, and use the adjusting rod 32 to adjust the height of the mounting plate 22, thereby adjusting the height of the discharge port 222 from the ground. Then drive the moving vehicle 10 to move, and move the storage box 20 to the construction area. The lime in the storage box 20 is evenly discharged into the construction area through the discharge port 222 to achieve lime spreading.
[0076] S4. After the lime is laid, measure the thickness of the paving on site. If it meets the requirements, carry out lime-soil mixing operation and drive the road mixer into the construction site to mix. Use a grader to roughly level the lime-soil from the inside to the outside, scrape up any obvious unevenness, and use a toothed rake to loosen the low-lying areas of the wheel tracks. Add lime-soil to level the surface.
[0077] S5. After the rough leveling construction is completed, the mixed lime soil is left to stand. After the standing is completed, a tire roller is used to quickly and statically compact the entire width once. Then, a grader is used to perform fine leveling according to the measured elevation control points.
[0078] S6. Finally, the road roller travels to the construction site and compacts the construction area to complete the laying of the lime-soil layer.
