Description

Technical Field

[0001] The invention relates to the field of permeable asphalt pavement structures, in particular to a permeable asphalt pavement structure. Background Art

[0002] Asphalt road, also known as asphalt road, is a common type of road pavement. It is mainly composed of a mixture of asphalt and aggregate. This mixture becomes plastic after heating, which is convenient for paving and compacting. Once cooled and hardened, it forms a strong, smooth and wear-resistant road surface, suitable for all weather conditions and traffic volume. The construction and maintenance of asphalt roads are relatively convenient, and can provide good driving comfort and noise control. However, with the updating and iteration of vehicles and the advancement of technology, the existing asphalt pavement gradually fails to meet people's daily use.

[0003] Existing asphalt pavement structures usually require the foundation to be compacted and compacted first. After it has a certain strength, the asphalt is mixed with gravel or sand to form a mixture and laid on the treated foundation. It is then compacted and shaped to achieve the desired effect.

[0004] As for the existing asphalt pavement structure, the pavement structure is relatively simple and lacks protective devices. In addition, the asphalt mixture is permeable. Rainwater passing through the asphalt mixture will cause certain erosion to the foundation, affecting the bearing strength of the pavement. In addition, in the summer when the temperature is high, the asphalt pavement will soften due to the high temperature. The squeezing of vehicles or heavy objects will cause damage to the pavement. The mixture formed by mixing asphalt with gravel or sand lacks internal reinforcement. It is easy to crack after long-term use, affecting the use of the pavement. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a permeable asphalt pavement structure to solve the technical problem that the existing asphalt pavement has poor drainage effect and affects the normal use of the pavement.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a permeable asphalt pavement structure, comprising a roadbed, a crushed stone layer is laid on the top of the roadbed, a concrete base block is arranged on the top of the crushed stone layer, concrete side plates are fixed on both sides of the concrete base block, a drainage pipe is arranged on one side of the concrete side plate, one end of the drainage pipe is connected to a water collecting pipe, a plurality of groups of left blocks and right blocks are arranged on the top of the concrete base block, and an asphalt surface is laid on the top of the concrete base block.

[0007] By adopting the above technical scheme, the problem that the existing asphalt pavement has poor drainage effect and affects the normal use of the pavement is solved. A crushed stone layer is laid on the foundation, a concrete base block is installed on the crushed stone layer, and concrete side panels are installed on both sides of the concrete base block. An asphalt surface is laid on the concrete side panels, and the top of the concrete base block is set as a curved surface. When it rains, since the asphalt surface is water-permeable, rainwater will penetrate from the asphalt surface to the top of the concrete base block and flow to both sides from the curved surface. A drainage ditch is opened at the connection between the concrete side panel and the concrete base block. The rainwater will flow into the drainage ditch and be introduced into the water collecting pipe through the drainage pipe on one side of the drainage ditch, thereby achieving a drainage effect on the rainwater, avoiding rainwater from gathering on the pavement and affecting the use of the pavement. The water collecting pipe diverts the rainwater to other places, which can avoid rainwater erosion of the foundation and thus affect the strength of the pavement.

[0008] The present invention is further configured such that flexible fiber strips are arranged inside the asphalt surface, and the flexible fiber strips are non-water-absorbent.

[0009] By adopting the above technical solution, by arranging flexible fiber strips inside the asphalt surface, and the flexible fiber strips are not water-absorbent, the stability of the asphalt surface can be enhanced and the asphalt surface can be prevented from cracking, thereby achieving the effect of extending the service life of the asphalt surface.

[0010] The present invention is further configured such that the left block and the right block are arranged obliquely, and the oblique directions of the left block and the right block are opposite.

[0011] By adopting the above technical solution, by tilting the left block and the right block, and the tilting directions of the left block and the right block are opposite, the pressure transmitted by the asphalt surface forms a certain angle with the left block and the right block. When the asphalt surface is softened to a certain extent in hot weather, the internal structure of the asphalt surface can be better stabilized to avoid damage to the asphalt surface and failure to meet the use effect.

[0012] The present invention is further configured such that inclination angles are provided on both sides of the drainage groove, and the other side of the drainage groove is connected to the water collecting pipe.

[0013] By adopting the above technical solution and setting inclined angles on both sides of the drainage ditch, the drainage area of ​​the drainage ditch can be increased, avoiding residual water accumulation on the surface of the concrete base block, thereby affecting the normal use of the road.

[0014] The present invention is further configured such that the top of the concrete base block is configured as a curved surface, and the left block and the right block are discontinuously configured on the top of the concrete base block.

[0015] By adopting the above technical solution, by setting the top of the concrete base block as a curved surface, a diversion effect is achieved for rainwater to avoid the accumulation of rainwater. The left block and the right block are set discontinuously on the top of the concrete base block to avoid the left block and the right block blocking the flow of rainwater, thereby failing to meet the drainage effect.

[0016] The present invention is further configured such that a plurality of sets of fixing rods are arranged at the bottom of the concrete base block, and the other ends of the fixing rods pass through the gravel layer and are fixed inside the roadbed.

[0017] By adopting the above technical solution, by setting the top of the concrete base block as a curved surface, a diversion effect is achieved for rainwater to avoid the accumulation of rainwater. The left block and the right block are set discontinuously on the top of the concrete base block to avoid the left block and the right block blocking the flow of rainwater, thereby failing to meet the drainage effect.

[0018] The present invention is further configured such that internal threads are provided at both ends of the interior of the drainage pipe, and multiple groups of drainage pipes are spliced ​​and aligned by sleeved connecting components inside the internal threads.

[0019] By adopting the above technical solution, internal threads are provided at both ends of the drain pipe, which facilitates the connection of the connecting components and enhances the laying efficiency of the drain pipe.

[0020] The present invention is further configured such that the drainage pipe is placed on a preset placement base to increase the contact area between the drainage pipe and the roadbed.

[0021] By adopting the above technical solution, by placing the water pipe on a preset placement base, the contact area between the drainage pipe and the roadbed is increased, the stability of the drainage pipe can be enhanced, and the drainage pipe can be prevented from moving after installation, thereby causing pipeline leakage and affecting the drainage effect.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. The present invention solves the problem that the existing asphalt pavement has poor drainage effect and affects the normal use of the pavement by arranging a water collecting pipe, a crushed stone layer, a concrete base block, a concrete side plate, a drainage pipe, a left block, a right block, a drainage groove and a fixing rod. The present invention provides a water collecting pipe, a crushed stone layer, a concrete base block, a concrete side plate on both sides of the concrete base block, an asphalt surface is laid on the concrete side plate, and the top of the concrete base block is set as a curved surface. When it rains, since the asphalt surface is water-permeable, rainwater will penetrate from the asphalt surface to the top of the concrete base block and flow to both sides from the curved surface. A drainage groove is opened at the connection between the concrete side plate and the concrete base block. Rainwater will flow into the drainage groove and be introduced into the water collecting pipe through the drainage pipe on one side of the drainage groove, thereby achieving a drainage effect on rainwater, avoiding rainwater from gathering on the pavement and affecting the use of the pavement. The water collecting pipe guides rainwater to other places, which can avoid rainwater erosion of the foundation and thus affecting the strength of the pavement.

[0024] 2. The present invention is provided with a concrete base block. A plurality of groups of left blocks and right blocks are provided on the surface of the concrete base block whose top is set as a curved surface. The left blocks and the right blocks are all inclined and have different inclination angles. Before paving the asphalt surface, a layer of hanging net is provided between the asphalt surface and the concrete base block. The hanging net can enhance the friction between the asphalt surface and the concrete base block, and enhance the stability of the asphalt surface and the concrete base block. The left blocks and the right blocks provided on the surface of the concrete base block will soften to a certain extent when the temperature is high in summer. The extrusion of vehicles or heavy objects will cause a certain dislocation of the internal structure of the asphalt surface, and damage the stability of the asphalt surface. The internal structure of the asphalt surface can be strengthened to a certain extent by providing the left blocks and the right blocks. Moreover, the left blocks and the right blocks are inclinedly provided on both sides of the top of the concrete base block. The inclined inner angle formed by the left blocks and the right blocks is the same as the contact position between the vehicle or the heavy object and the asphalt surface, which can better absorb the pressure transmitted by the vehicle or the heavy object, maintain the internal structure of the asphalt surface, and avoid the damage of the asphalt surface. In the process of making the asphalt surface, flexible fiber strips are placed to enhance the strength of the asphalt surface and avoid the cracking of the asphalt surface due to long-term use.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Embodiment 1

[0038] A permeable asphalt pavement structure, such as Figure 1 - Figure 4 As shown, it includes a roadbed 1, a crushed stone layer 2 is laid on the top of the roadbed 1, and the crushed stone layer 2 can play a buffering role on the concrete base block 3, disperse the force of the roadbed 1, and extend the service life of the road. A concrete base block 3 is arranged on the top of the crushed stone layer 2, and concrete side panels 4 are fixed on both sides of the concrete base block 3. A drainage pipe 6 is arranged on one side of the concrete side panel 4, and one end of the drainage pipe 6 is connected to a water collecting pipe 5. Rainwater flowing on the concrete base block 3 is deliberately discharged through the water collecting pipe 5, so as to prevent rainwater from eroding the roadbed 1. A plurality of groups of left blocks 7 and right blocks 71 are arranged on the top of the concrete base block 3, and an asphalt surface 9 is laid on the top of the concrete base block 3. By arranging the left blocks 7 and the right blocks 71, when the asphalt surface 9 is softened to a certain extent in hot weather, a certain restraining effect can be played on the asphalt surface 9 to maintain the internal stability of the asphalt surface 9.

[0039] See also Figure 1 and Figure 4Flexible fiber strips are arranged inside the asphalt surface 9, and the flexible fiber strips are non-absorbent. By arranging flexible fiber strips inside the asphalt surface 9, and the flexible fiber strips are non-absorbent, the stability of the asphalt surface 9 can be enhanced and the asphalt surface 9 can be prevented from cracking, thereby achieving the effect of extending the service life of the asphalt surface 9.

[0040] See also Figure 2 The left block 7 and the right block 71 are tilted, and the tilt directions of the left block 7 and the right block 71 are opposite. By tilting the left block 7 and the right block 71, and the tilt directions of the left block 7 and the right block 71 are opposite, the pressure transmitted by the asphalt surface 9 forms a certain angle with the left block 7 and the right block 71. When the asphalt surface 9 is softened to a certain extent in hot weather, the internal structure of the asphalt surface 9 can be better stabilized to avoid damage to the asphalt surface 9 and failure to meet the use effect.

[0041] See also Figure 2 and Figure 3 The drainage ditch 8 is provided with an inclined angle on both sides, and the other side of the drainage ditch 8 is connected to the water collecting pipe 5. By providing the drainage ditch 8 with an inclined angle on both sides, the diversion area of ​​the drainage ditch 8 can be increased, thereby avoiding residual water accumulation on the surface of the concrete base block 3, thereby affecting the normal use of the road.

[0042] See also Figure 2 The top of the concrete base block 3 is set as a curved surface, and the left block 7 and the right block 71 are set discontinuously on the top of the concrete base block 3. By setting the top of the concrete base block 3 as a curved surface, a diversion effect is achieved for rainwater to avoid the accumulation of rainwater. The left block 7 and the right block 71 are set discontinuously on the top of the concrete base block 3 to avoid the left block 7 and the right block 71 blocking the flow of rainwater, thereby failing to meet the drainage effect.

[0043] See also Figure 4 A plurality of fixing rods 10 are arranged at the bottom of the concrete foundation block 3, and the other ends of the fixing rods 10 pass through the gravel layer 2 and are fixed inside the roadbed 1. By arranging a plurality of fixing rods 10 at the bottom of the concrete foundation block 3, and the other ends of the fixing rods 10 pass through the gravel layer 2 and are fixed inside the roadbed 1, the stability of the concrete foundation block 3 can be effectively enhanced, and the concrete foundation block 3 can be prevented from loosening, thereby affecting the normal use of the road.

[0044] See also Figure 1 Internal threads are provided at both ends of the drain pipe 6. Multiple groups of drain pipes 6 are spliced ​​and aligned by arranging connecting components inside the internal threads. Internal threads are provided at both ends of the drain pipe 6 to facilitate the connection of the connecting components and enhance the laying efficiency of the drain pipe 6.

[0045] See also Figure 4The drainage pipe 6 is placed on a preset placement base to increase the contact area between the drainage pipe 6 and the roadbed 1. By placing the drainage pipe 6 on a preset placement base to increase the contact area between the drainage pipe 6 and the roadbed 1, the stability of the drainage pipe 6 can be enhanced, and the drainage pipe 6 can be prevented from moving after installation, thereby causing pipeline leakage and affecting the drainage effect.

[0046] Embodiment 2

[0047] A permeable asphalt pavement structure, such as Figure 4 - Fig. 9 As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the same technical parts will not be repeated here. The difference is that (if there are not two solutions to the same problem, it can be written as follows: a drainage base 15 is fixedly installed on both sides of the concrete side plate 4, and a drainage vertical cavity 14, a drainage horizontal cavity 141 and a drainage chute 152 are opened inside the drainage base 15, and the drainage chute 152 is aligned with the drainage groove 8. The drainage vertical cavity 14 and the drainage horizontal cavity 141 penetrate each other, and connecting pipes 151 are installed at both ends of the drainage horizontal cavity 141. A sealing rubber ring is placed at the end of the connecting pipe 151, and one end of the connecting pipe 151 and the sealing rubber ring are sleeved on the drainage inner groove 111 in the horizontal pipe 11. A placement groove 153 is opened at one end of the drainage vertical cavity 14, and a manhole cover 12 is installed in the placement groove 153. An annular protrusion is arranged in the drainage vertical cavity 14, and a filter plate 13 is movably installed on the annular protrusion. A collecting protrusion 131 is installed on the top of the filter plate 13. Two groups of hooks 132 are fixedly installed on the top of the collecting protrusion 131. The annular protrusion and the collecting protrusion 131 are both arranged at the bottom of the drainage chute 152.

[0048] By fixing a plurality of drainage bases 15 on one side of the concrete side plate 4, rainwater can enter the drainage transverse cavity 141 through the aligned drainage chute 152 and the drainage groove 8, and flow into the transverse pipe 11 through the connecting pipes 151 at both ends of the drainage transverse cavity 141, and be diverted to other places through the transverse pipe 11 to prevent rainwater from seeping into and corroding the roadbed 1. A sealing rubber ring is placed at one end of the connecting pipe 151, which is on the drainage inner groove 111 sleeved in the transverse pipe 11, and can effectively enhance the sealing performance when the connecting pipe 151 is connected to the transverse pipe 11 to prevent rainwater from seeping into. An annular protrusion is arranged in the drainage vertical cavity 14 opened in the drainage base 15, and the annular protrusion can limit the filter plate 13 sleeved in the drainage vertical cavity 14, so that the filter plate 13 can pass through the drainage chute 15 2. The rainwater flowing in is filtered to prevent stones brought in by the rainwater from entering the drainage transverse cavity 141, thereby causing blockage inside the connecting pipe 151 and the transverse pipe 11, affecting the drainage effect of the connecting pipe 151 and the transverse pipe 11. The collecting protrusion 131 is arranged on the top of the filter plate 13 to limit the stones collected by the filter plate 13. When the staff takes out the filter plate 13 through the hook 132 fixedly installed on the top of the collecting protrusion 131, the stones will not fall through the edge of the filter plate 13. A placement groove 153 is opened at the top of the drainage vertical cavity 14, and the manhole cover 12 is installed in the placement groove 153 to prevent external obstacles from entering the drainage vertical cavity 14 and affecting the drainage effect of the drainage base 15. Two convex grooves are opened on both sides of the placement groove 153 to facilitate the installation and removal of the manhole cover 12.

[0049] The working principle of the present invention is as follows: before laying the gravel layer 2, the roadbed 1 needs to be compacted first so that the roadbed 1 has a certain strength and can bear the load better. A plurality of groups of reserved holes are opened inside the roadbed 1 and the gravel layer 2. After the roadbed 1 is compacted and the gravel layer 2 is laid, the prefabricated concrete base block 3 is placed on the top of the gravel layer 2. A fixing rod 10 is arranged on one side of the concrete base block 3, and the fixing rod 10 is sleeved into the inside of the reserved hole. The diameter of the reserved hole is smaller than the diameter of the fixing rod 10, so that the wall of the reserved hole has a certain extrusion on the fixing rod 10 after the fixing rod 10 is sleeved, which can enhance the stability of the concrete base block 3. Then, a hanging net is laid on the top of the concrete base block 3, and when the asphalt surface 9 is laid, a plurality of groups of inclined left blocks 7 and right blocks 71 are arranged on the top of the concrete base block 3. After the asphalt surface 9 is laid, the asphalt surface 9 needs to be spread and compacted so that it is aligned with the left Block 7 is in full contact with the right block 71, thereby strengthening the stability of the internal structure of the asphalt surface 9, so that the asphalt surface 9 can achieve the use effect of the road surface, and flexible fiber strips will be added in the production process of the asphalt surface 9. The flexible fiber strips can enhance the stability of the asphalt surface 9 and prevent the asphalt surface 9 from cracking due to long-term use, thereby extending the service life of the road surface. Since the asphalt surface 9 has a water-permeable effect, when it rains, rainwater will flow through the asphalt surface 9 to the top of the concrete base block 3. The top of the concrete base block 3 is a curved surface, which will divert the rainwater to the drainage ditch 8 opened between the concrete base block 3 and the concrete side plate 4. The rainwater will be introduced into the water collecting pipe 5 by the drainage pipe 6 on one side of the drainage ditch 8. The drainage pipe 6 is inclined, which can achieve a better diversion effect. The water collecting pipe 5 will divert the rainwater to other places to prevent rainwater from seeping into and eroding the roadbed 1, reducing the strength of the road surface, and affecting the service life of the road surface.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
