Water-permeable pavement and construction method thereof

Abstract

This application discloses a permeable pavement and its construction method, relating to the field of road engineering technology. The application includes a base layer with a receiving groove extending along its length on one side, containing a drainage pipe. By employing a design with multiple hexagonal prisms, rainwater can sequentially pass through the top layer, the filling layer, the through-holes, and the water passage, and then drain into the drainage pipe through the inlet. When vehicles are traveling, the multiple hexagonal prisms support the top layer, improving its structural strength and effectively distributing the pressure from the tires, making it less prone to deformation and damage. Compared to existing technologies, this method eliminates the need to excessively increase the thickness of the permeable asphalt pavement, effectively reducing a series of problems affecting pavement smoothness caused by increased pavement thickness.

Description

Technical Field

[0001] This application relates to the field of road engineering technology, specifically to a permeable pavement and its construction method. Background Technology

[0002] Asphalt pavements can be classified into permeable asphalt pavements (generally composed of two layers, with the inner layer of permeable asphalt having a larger particle diameter than the outer layer of permeable asphalt) and impermeable asphalt pavements based on their permeability. Permeable asphalt pavements use large-void asphalt mixtures, which have large surface gaps and extremely high permeability. They have the advantages of reducing road water accumulation and alleviating urban flooding, and can improve driving safety during rainstorms. Therefore, they are widely used in urban road construction.

[0003] Permeable asphalt pavement has poor compressive strength and is easily damaged by the pressure exerted by vehicles (trucks, buses, public buses, and fire trucks, etc.) in urban areas. In existing technologies, pavement thickness is often increased to improve its compressive strength. However, the thickness increase of permeable asphalt pavement is much greater than that of ordinary pavement when improving compressive strength. This makes permeable asphalt pavement prone to cracking due to internal temperature and tension, or due to the inconsistency between surface heating and internal shrinkage pressure, resulting in pavement bulges, affecting pavement smoothness and driving safety. In order to reasonably improve this problem, this application proposes a permeable pavement and its construction method. Summary of the Invention

[0004] The purpose of this application is to address the technical problem that in the prior art, pavement often improves its compressive strength by increasing its thickness. However, when permeable asphalt is used to improve compressive strength, the thickness increase is much greater than that of ordinary pavement. This leads to permeable asphalt pavement being prone to cracking due to internal temperature and tension, or to pavement bulging due to inconsistent surface heating and internal shrinkage pressure, affecting pavement smoothness and driving safety. This application provides a permeable pavement and its construction method.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A permeable pavement, comprising:

[0007] The base layer has a receiving groove extending along its length on one side, which contains a drain pipe. The drain pipe has multiple water inlets evenly distributed on it. The top of the base layer is covered with multiple hexagonal prisms in a honeycomb pattern, with through holes coaxially opened inside. The bottom of the hexagonal prisms has multiple through grooves distributed in a ring, and all the through grooves are connected to the through holes.

[0008] A filler layer, located on top of the base layer, covers the drainage pipes and fills multiple through holes;

[0009] The top layer is located on top of multiple hexagonal prisms.

[0010] The construction method for permeable pavement is as follows:

[0011] S1: Fill the roadbed, open a pit on the road, pour concrete into it to form the base course, and reserve a receiving groove on the side close to the curb.

[0012] S2: Lay the pipes, place the drainage pipes in the receiving tank, and lay a layer of geotextile on top to cover the water inlet.

[0013] S3: Lay hexagonal prisms, using placement equipment to arrange multiple hexagonal prisms one by one closely on the top of the base layer;

[0014] S4: Lay the filling layer by covering the receiving groove with permeable asphalt coarse material, filling the gap between the hexagonal prism and the base layer, and injecting it into multiple through holes to form the filling layer;

[0015] S5: Lay the top layer by laying permeable asphalt fines on top of multiple hexagonal prisms and the infill layer to form the top layer;

[0016] S6: Compaction, using compaction equipment to compact the top layer;

[0017] The construction of permeable pavement in the above preparation methods S1-S6 requires the use of equipment, among which:

[0018] The equipment includes a vehicle body and a rear compartment. Telescopic guide rails are installed on both sides of the rear compartment. The movable ends of the two telescopic guide rails are connected to each other. A first driving component is provided in the rear compartment, which is used to drive the movable ends of the telescopic guide rails to slide.

[0019] Two support rods are connected to the movable ends of two telescopic guide rails, and each support rod is equipped with a caster wheel at its bottom end;

[0020] An adjustment mechanism, located on the support rod, is used to adjust the length of the support rod;

[0021] Two sliders are slidably engaged with the movable ends of two telescopic guide rails respectively. A connecting frame is provided between the two sliders. The connecting frame is connected to the two sliders through a horizontal drive assembly. One of the telescopic guide rails has a second drive component at its movable end, which is used to drive the slider to slide.

[0022] The mounting plate is slidably mounted on the connecting frame via a vertical drive assembly. Multiple columnar rods are distributed at the bottom of the mounting plate, with the columnar rods movably passing through through holes. A fixing mechanism for fixing the hexagonal prism is provided around the columnar rods.

[0023] Furthermore, the adjustment mechanism includes a slot constructed at the bottom of the support rod, in which a movable rod is slidably fitted, a caster wheel is mounted at the bottom end of the movable rod, a transmission screw is rotatably installed in the slot and threadedly fitted with the movable rod, and a wheel is rotatably installed on the outside of the support rod, the wheel's central shaft passing through the slot and being connected to the end of the transmission screw via a bevel gear assembly.

[0024] Furthermore, the fixing mechanism includes a sleeve slidably fitted onto the bottom end of the cylindrical rod, which is connected to the cylindrical rod via a compression spring. Multiple first connecting rods are hinged to the outer side of the cylindrical rod, and the multiple first connecting rods are arranged in a ring. Each of the first connecting rods has a stop plate hinged to its end. Each stop plate has a second connecting rod hinged to its end. The ends of the multiple second connecting rods are hinged to the periphery of the sleeve. The outer side of the stop plate abuts against the inner wall of the through hole. Each cylindrical rod is provided with a locking element for fixing the sleeve.

[0025] Furthermore, the abutment is resilient and has transverse grooves on its outer side, with multiple transverse grooves arranged linearly along the length of the abutment.

[0026] Furthermore, the locking component includes an annular block that is slidably sleeved around the cylindrical rod. The bottom end of the annular block is connected to the sleeve via multiple connecting strips, and its top end is constructed with a guide slope. A connecting rod is hinged to the outside of the cylindrical rod, and a locking block is constructed at its bottom end. A guide surface is constructed on the block, and the guide surface and the guide slope are movably overlapped. A power component is provided at the top of the cylindrical rod, which is used to drive the locking block away from the cylindrical rod.

[0027] Furthermore, the power component includes a movable plate, multiple cylindrical rods slidingly passing through the movable plate, an electromagnet mounted on the mounting plate and magnetically connected to the top of the movable plate, and multiple connecting rods movably hinged to the bottom of the movable plate.

[0028] Furthermore, the connecting rod has a curved section, the top of the connecting rod is far from the columnar rod, and a waist hole is opened on it.

[0032] 1. This application employs a design with multiple hexagonal prisms, allowing rainwater to sequentially pass through the top layer, filling layer, through holes, and water passages, and then drain into the drainage pipe through the inlet. When vehicles are in motion, the multiple hexagonal prisms support the top layer, improving its structural strength and effectively distributing the pressure generated by the tires, making it less prone to deformation and damage. Compared with existing technologies, it does not require excessively increasing the thickness of the permeable asphalt pavement, effectively reducing a series of problems affecting road surface smoothness caused by increased pavement thickness.

This application employs a design that combines a telescopic guide rail, a first driving component, a slider, a horizontal driving assembly, a connecting frame, a second driving component, a mounting plate, and a vertical driving assembly. This allows the mounting plate to be moved, enabling the hexagonal prisms to be picked up and quickly stacked or arranged via a fixing mechanism on the column rod. This reduces the labor intensity of workers and improves their work efficiency. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0044] like Figure 1 As shown, one embodiment of this application proposes a permeable pavement, comprising:

[0045] The base layer 1 is a concrete base layer 1. A receiving groove 2 extending along its length is opened on one side of the base layer 1. The receiving groove 2 is located at the bottom of the curbstone to prevent it from being crushed by vehicles. The groove 2 contains a drainage pipe 3. Multiple water inlets 4 are evenly distributed on the drainage pipe 3. The multiple water inlets 4 are all located at the top of the drainage pipe 3. Multiple hexagonal prisms 5 are laid in a honeycomb pattern on the top of the base layer 1. These are quartz bricks in the shape of regular hexagonal prisms 5. Through holes 6 are opened coaxially in the bricks. The cross-section of the through holes 6 is hexagonal. Multiple through grooves 7 are distributed in a ring at the bottom of the hexagonal prisms 5. The number of through grooves 7 is the same as the number of edges of the hexagonal prisms 5. The through grooves 7 are arched, have high compressive strength, and are not easily damaged. After the multiple hexagonal prisms 5 are laid, the adjacent through grooves 7 are connected to each other. This creates a water passage at the bottom of the hexagonal prisms 5 and the top of the base layer 1 that is higher than the multiple water inlets 4. The through grooves 7 are all connected to the through holes 6. Rainwater can enter the water passage through the through holes 6 and be discharged into the drainage pipe 3 through the water inlets 4.

[0046] The filler layer 8 is made of permeable asphalt and coarse aggregate. It is placed on top of the base layer 1, covering the drainage pipe 3 and filling multiple through holes 6. Rainwater can pass through the through holes 6 and through the filler layer 8. When constructing the filler layer 8, the gaps between the edge of the base layer 1 and multiple hexagonal prisms 5 can also be filled.

[0047] The top layer 9 is made of a mixture of permeable asphalt and fine aggregate. It is located on top of multiple hexagonal prisms 5. The top layer 9 is laid on top of the infill layer 8 and the hexagonal prisms 5. It should be noted that the minimum width of the through hole 6 is less than the width of a small car tire. When a vehicle drives on the top layer 9, the multiple hexagonal prisms 5 can support the top layer 9, which can improve its structural strength and effectively distribute the pressure generated by the tire.

[0048] This application employs a design with multiple hexagonal prisms 5, allowing rainwater to sequentially pass through the top layer 9, the filling layer 8, the through holes 6, and the water passage, before draining into the drainage pipe 3 through the inlet 4. When vehicles are in motion, the multiple hexagonal prisms 5 support the top layer 9, improving its structural strength and effectively distributing the pressure generated by the tires, making it less prone to deformation and damage. Compared with existing technologies, this design eliminates the need to excessively increase the thickness of the permeable asphalt pavement, effectively reducing a series of problems affecting road surface smoothness caused by increased pavement thickness.

[0049] like Figures 2-8 As shown in the figure, a construction method for permeable pavement according to one embodiment of this application is as follows:

[0050] S1: Fill the roadbed, open a pit on the road, pour concrete into it to form the base course 1, and reserve a receiving groove 2 on one side of it;

[0051] S2: Lay the pipe, lay the drain pipe 3 in the receiving tank 2, and lay a layer of geotextile on it to cover the water inlet 4.

[0052] S3: Lay hexagonal prisms 5, and arrange multiple hexagonal prisms 5 one by one on the top of the base layer 1 using a placement device;

[0053] S4: Lay the filling layer 8, cover the receiving groove 2 with permeable asphalt coarse material, fill the gap between the hexagonal prism 5 and the base layer 1, and inject it into multiple through holes 6 to form the filling layer 8.

[0054] S5: Lay the top layer 9 by laying permeable asphalt fine material on top of multiple hexagonal prisms 5 and the filler layer 8 to form the top layer 9;

[0055] S6: Compacting, compacting the top layer 9 using compaction equipment;

[0056] The construction of permeable pavement in the above preparation methods S1-S6 requires the use of equipment, among which:

[0057] The equipment includes a vehicle body 10 and a rear compartment 11. The structure here is similar to a truck. Multiple hexagonal prisms 5 can be stacked in a honeycomb pattern inside the rear compartment 11, and the through holes 6 of different layers of hexagonal prisms 5 are staggered. Telescopic guide rails 12 are installed on both sides of the rear compartment 11. The number of two telescopic guide rails 12 is symmetrically arranged on the top of the two side panels of the rear compartment 11. The fixed end of the telescopic guide rail 12 is fixed to the rear compartment 11, and the movable ends of the two telescopic guide rails 12 are connected to each other so that they can slide synchronously. A first driving component 13 is provided inside the rear compartment 11, which is used to drive the movable end of the telescopic guide rail 12 to slide. The first driving component 13 includes a first lead screw 1301 rotatably installed on the fixed end of one of the telescopic guide rails 12, which is threadedly engaged with the movable end of one of the telescopic guide rails 12. A first motor 1302 is connected to the end of the first lead screw 1301. When the first motor 1302 works, it can drive the first lead screw 1301 to rotate, thereby controlling the extension and retraction of the telescopic guide rail 12.

[0058] Two support rods 14 are connected to the movable ends of two telescopic guide rails 12 respectively. The two support rods 14 are parallel to each other and arranged symmetrically. The support rods 14 are perpendicularly connected to the movable ends of the telescopic guide rails 12. Each support rod 14 is equipped with a universal wheel 15 at its bottom.

[0059] An adjustment mechanism 16 is provided on the support rod 14 and is used to adjust the length of the support rod 14, thereby adjusting the height of the caster wheel 15 to adapt to different heights of the base layer 1.

[0060] Two sliders 17 are slidably engaged with the movable ends of two telescopic guide rails 12, respectively. The sliders 17 can slide on the movable ends of the telescopic guide rails 12. A connecting frame 18 is provided between the two sliders 17. The connecting frame 18 is connected to the two sliders 17 via a horizontal drive assembly 19. The horizontal drive assembly 19 includes a guide rod 1901 connecting the opposite sides of the two sliders 17 and a reciprocating screw 1902 rotatably engaged with the two sliders 17. A drive motor 1903 is mounted on one of the sliders 17, and its output end is connected to the end of the reciprocating screw 1902. The connecting frame 18 is slidably engaged with the guide rod 1901 and threadedly engaged with the reciprocating screw 1902. When the drive motor 1903 is working, it can... The connecting frame 18 is driven to slide back and forth on the guide rod 1901 by the reciprocating screw 1902, thereby moving the connecting frame 18 to slide between the two sliders 17. A second driving member 20 is provided at the movable end of one of the telescopic guide rails 12, which is used to drive the slider 17 to slide. The second driving member 20 includes a second screw 2001 rotatably mounted on the movable end of one of the telescopic guide rails 12, which is threadedly engaged with one of the sliders 17. A second motor 2002 is connected to the end of the second screw 2001. When the second motor 2002 is working, it can drive the second screw 2001 to rotate, thereby adjusting the position of the connecting frame 18 on the movable end of the telescopic guide rail 12 by controlling the slider 17 to slide.

[0061] Mounting plate 21 is slidably mounted on connecting frame 18 via vertical drive assembly 22. Vertical drive assembly 22 is specifically a multi-stage telescopic rod driven by a motor. Mounting plate 21 is mounted on its output end. Multiple columnar rods 23 are distributed at the bottom of mounting plate 21. In this application, the preferred number of columnar rods 23 is nine. Each columnar rod 23 movably passes through a through hole 6. A fixing mechanism 24 for fixing the hexagonal prism 5 is provided around the columnar rod 23. When the vehicle body 10 and rear compartment 11 move forward on the base layer 1, the connecting frame 18 can first be moved to the position of the rear compartment 11 via horizontal drive assembly 19 and second drive component 20. Then, the mounting plate 21 is driven downwards by vertical drive assembly 22, allowing the multiple columnar rods 23 to be inserted one-to-one into the rear compartment. The hexagonal prism 5 is inserted into multiple through holes 6 on the carriage 11 and fixed to multiple columnar rods 23 by a fixing mechanism 24. At this time, the adjacent hexagonal prisms 5 are tightly fitted together. Then, the mounting plate 21 can be lifted first, and then the telescopic guide rail 12 can be extended to move the mounting plate 21 out of the rear carriage 11. At the same time, with the cooperation of the caster wheel 15 and the support rod 14, the pressure caused by the hexagonal prism 5 on the telescopic guide rail 12 when it extends and retracts its movable end can be reduced. Then, the horizontal drive component 19 and the second drive component 20 move the connecting frame 18 to the position of the base layer 1, and the vertical drive component 22 drives the mounting plate 21 to slide down. Finally, the fixing mechanism 24 releases the fixing of the hexagonal prism 5 to complete the placement of the hexagonal prism 5.

[0062] This application employs a design that combines a telescopic guide rail 12, a first driving component 13, a slider 17, a horizontal driving assembly 19, a connecting frame 18, a second driving component 20, a mounting plate 21, and a vertical driving assembly 22. This design allows the mounting plate 21 to be moved, enabling the hexagonal prism 5 to be picked up and quickly stacked or placed via the fixing mechanism 24 on the column rod 23. This reduces the labor intensity of workers and improves their work efficiency.

[0063] like Figures 3-5 As shown, in some embodiments, the adjusting mechanism 16 includes a slot 1601 constructed at the bottom of the support rod 14, the slot 1601 extending along the length of the support rod 14, a movable rod 1602 slidably fitted inside the slot 1601, a caster wheel 15 mounted at the bottom end of the movable rod 1602, a transmission screw 1603 rotatably mounted inside the slot 1601, the transmission screw 1603 being parallel to the slot 1601 and threadedly engaged with the movable rod 1602, and a rotating wheel 1604 rotatably mounted on the outer side of the support rod 14. The rotating wheel 1604 is mounted on opposite sides of the two support rods 14. Its central shaft passes through the slot 1601 and is connected to the end of the transmission screw 1603 via a bevel gear assembly 1605. The bevel gear assembly 1605 consists of two bevel gears, which are respectively mounted on the central shaft of the rotating wheel 1604 and the end of the screw. When the rotating wheel 1604 is rotated, the screw can be driven to rotate through the bevel gear assembly 1605, thereby driving the movable rod 1602 to move downward, thus allowing the height of the caster wheel 15 to be adjusted.

[0064] like Figure 3 , Figure 6 and Figure 8As shown, in some embodiments, the fixing mechanism 24 includes a sleeve 2401 slidably fitted onto the bottom end of the cylindrical rod 23. The sleeve 2401 is located on the outside of the cylindrical rod 23 and is connected to the cylindrical rod 23 via a compression spring 2402. The compression spring 2402 is used to push the sleeve 2401 away from the cylindrical rod 23. A plurality of first connecting rods 2403 are hinged to the outside of the cylindrical rod 23. The number of first connecting rods 2403 is the same as the number of edges of the hexagonal prism 5. The plurality of first connecting rods 2403 are arranged in a ring, and each of their ends is hinged to a stop plate 2404. A second connecting rod 2405 is hinged to each stop plate 2404. The first connecting rods 2403 and the second connecting rods 2405 are both hinged to the inner side of the stop plate 2404, that is, to the side facing the cylindrical rod 23. The ends of the plurality of second connecting rods 2405 are all hinged to the periphery of the sleeve 2401. The outer side of the stop plate 2404 abuts against and overlaps with the inner wall of the through hole 6. Each cylindrical rod 23 is equipped with a locking element 25, which is used to fix the sleeve 2401. When the cylindrical rod 23 is fully inserted into the through hole 6 of the hexagonal prism 5, the sleeve 2401 can abut against the road surface or the top of other hexagonal prisms 5. At this time, the cylindrical rod 23 continues to move downward, and the sleeve 2401 slides on the cylindrical rod 23. At this time, multiple first connecting rods 2403 and second connecting rods 2405 approach each other, and multiple abutment plates 2404 hinged at their ends abut against multiple inner walls of the through hole 6. Then, the sleeve 2401 can be fixed by the fixing mechanism 24, thereby fixing the hexagonal prism 5. After placement is completed, the fixing mechanism 24 can be released to fix the sleeve 2401. At this time, the sleeve 2401 moves away from the cylindrical rod 23 under the action of the compression spring 2402. At the same time, the abutment plate 2404 separates from the inner wall of the through hole 6, thereby separating the cylindrical rod 23 from the hexagonal prism 5.

[0065] like Figure 6 and Figure 8 As shown, in some embodiments, the abutment 2404 is resilient and made of rubber. This design allows the abutment 2404 to fit tightly against the inner wall of the through hole 6, making it difficult to separate from the inner wall of the through hole 6. Furthermore, a transverse groove 26 is provided on its outer side. Multiple transverse grooves 26 are arranged linearly along the length of the abutment 2404. The design of the transverse groove 26 is used to increase the roughness of the outer side of the abutment 2404, making it difficult for the abutment 2404 to slide on the inner wall of the through hole 6 when the hexagonal prism 5 moves.

[0066] like Figures 6-8As shown, in some embodiments, the locking member 25 includes an annular block 2501, which is slidably sleeved around the cylindrical rod 23. The annular block 2501 is located above the first connecting rod 2403. The bottom end of the annular block 2501 is connected to the sleeve 2401 through multiple connecting strips 2502. The number of connecting strips 2502 is the same as that of the first connecting rod 2403, and the two are arranged in a staggered manner. The top end of the annular block 2501 is constructed with a guide slope 2503. The outer diameter of the annular block 2501 gradually decreases from bottom to top. Two connecting rods 2504 are hinged to the outside of the cylindrical rod 23. The number of connecting rods 2504 is two, and they are arranged in a ring. The connecting rods 2504 are located above the annular block 2501. The bottom end of the connecting rod is constructed with a locking block 2505. The locking block 2505 extends towards the cylindrical rod 23. Under the action of gravity, the locking block 2505 contacts the periphery of the cylindrical rod 23. A guide surface 2506 is constructed on the locking block 2504. The width of the locking block 2505 gradually decreases from top to bottom. The guide surface 2506 and the guide slope 2503 are movably overlapped. When the sleeve 2401 drives the annular block 2501 to slide upward, the guide slope 2503 can abut against the guide surface 2506. At this time, the locking block 2505 can slide along the guide slope 2503. After the locking block 2505 passes the annular block 2501, the locking block 2505 resets and contacts the cylindrical rod 23. At this time, the locking block 2505 abuts against the opposite side of the annular block 2501, preventing the sleeve 2401 from moving downward. The top of the cylindrical rod 23 is provided with a power component 27, which is used to drive the locking block 2505 away from the cylindrical rod 23. The power component 27 drives the connecting rod 2504 to rotate along the hinge point. When the locking block 2505 moves away from the cylindrical rod 23, the locking block 2505 separates from the annular block 2501. At this time, the fixing of the sleeve 2401 can be released.

[0067] like Figures 6-8 As shown, in some embodiments, the power component 27 includes a movable plate 2701, with multiple cylindrical rods 23 slidingly passing through the movable plate 2701. The movable plate 2701 is located above the connecting rods 2504 and slides in cooperation with the multiple cylindrical rods 23. An electromagnet 2702 is mounted on the mounting plate 21, located at the bottom of the mounting plate 21 and magnetically connected to the top of the movable plate 2701. The movable plate 2701 is made of stainless steel. The multiple connecting rods 2504 are hinged to the bottom of the movable plate 2701. When the electromagnet 2702 is closed, the movable plate 2701 slides downward under the action of gravity. By linking the multiple connecting rods 2504 with the movable plate 2701, when the electromagnet 2702 is open, it can attract the movable plate 2701 upward, thereby driving the multiple connecting rods 2504 to rotate along the hinge point, causing the locking block 2505 to separate from the cylindrical rods 23, thereby releasing the fixation of the multiple hexagonal prisms 5.

[0068] like Figure 6 and Figure 7As shown, in some embodiments, the connecting rod 2504 has a curved portion 28. The top end of the connecting rod 2504 is far from the cylindrical rod 23. The top end of the connecting rod 2504 is located on the curved portion 28 and has a waist hole 29. A vertical plate 30 is connected to the movable plate 2701 and a guide rod 31 is connected to its end. The guide rod 31 slides tangentially to the inner wall of the waist hole 29. When the movable plate 2701 slides down, under the contact of the guide rod 31, the locking blocks 2505 on multiple connecting rods 2504 all abut against the periphery of the cylindrical rod 23. During the upward movement of the movable plate 2701, the guide rod 31 moves synchronously and moves within the waist hole 29. Because it is tangential to the waist hole 29, it drives the connecting rod 2504 to rotate around the hinge point, causing the locking blocks 2505 to separate from the cylindrical rod 23.

[0069] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the top of the mounting plate 21 is constructed with a box 32, which is made of stainless steel. Columnar rods 23 are constructed at the bottom of the box 32, and a through groove 33 communicating with the box 32 is opened at the bottom of the columnar rods 23. A ground pump 34 is installed on the rear compartment 11. The ground pump 34 is a shorthand for a concrete conveying pump, which is existing technology and can convey permeable asphalt coarse material. Its output end is connected to the box 32, and the two are connected by a rubber hose, so that the box 32 is not affected when it moves with the mounting plate 21. With this design, when the ground pump 34 is working, it can convey permeable asphalt coarse material into the box 32 and from the through groove 33 to the bottom of multiple columnar rods 23. After placement, the permeable asphalt coarse material can also be filled into multiple through holes 6, thereby improving work efficiency.

[0070] like Figure 6 and Figure 8 As shown, in some embodiments, the bottom end of the sleeve 2401 is connected to an annular pad 35. The annular pad 35 is a rubber pad, which is tough and its inner diameter is larger than the outer diameter of the cylindrical rod 23. This design can reduce the rigid collision between the bottom end of the sleeve 2401 and the ground or other hexagonal prisms 5 when the hexagonal prism 5 is picked up, so that the sleeve 2401 is not easily deformed and is not easily blocked from the bottom opening of the through groove 33.

[0071] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
