Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a porous sound-absorbing asphalt pavement structure. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface durable. It is one of the most widely used high-grade roads in road construction.

[0003] After searching, a Chinese patent discloses a porous, permeable, and aging-resistant environmentally friendly asphalt pavement (authorization announcement number CN216786740U), including: an asphalt pavement body, wherein the asphalt pavement body is composed of an upper layer, a middle layer, a permeable layer, an upper base layer, a first crushed stone layer, a first drainage layer, and a bottom base layer from top to bottom, and the upper layer is a large-pore asphalt mixture noise reduction functional layer; although this patented technology will not cause a large amount of rainwater to accumulate on the road surface, affecting driving safety, and has high safety performance, it also has a certain sound absorption function, effectively reducing the noise generated by friction between the wheels and the road surface, and is environmentally friendly. In addition, the asphalt pavement is more stable and the bearing capacity of the base layer is strong, which comprehensively improves the permeability, aging resistance, and noise reduction performance of the asphalt pavement.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that in order to achieve the drainage function, the above asphalt pavement is provided with a drainage outlet at the curb, and the accumulated water on the road surface is guided into the drainage ditch through the drainage outlet. However, this method can only be achieved when the road surface is absolutely clean. Once stones or garbage appear on the road surface, as rainwater gathers on rainy days, it is easy to cause the drainage outlet to be blocked, and the water will accumulate in the drainage ditch, affecting the drainage capacity of the drainage ditch.

[0018] As a preferred embodiment, the drainage channel is arranged as a whole at an angle, a hidden handle is provided at one end of the top of the grid plate, and a raised surface is provided at the top of the asphalt pavement body to facilitate the flow of rainwater.

The grille plates 8 are connected to the curbs 4 through the hinges 9. On rainy days, rainwater will flow into the water inlet grooves 7 along the inclined surface on the asphalt pavement body 6, and then be guided into the drainage channel 3 through the drainage grooves 5, and then be guided into the drainage channel 3 through the drainage grooves 5. The drainage channel 3 discharges rainwater in a unified manner, reducing the accumulation of rainwater on the asphalt pavement body 6, thereby reducing the slipping of vehicles. Through the setting of the grille plate 8, the stones and garbage mixed in the rainwater can be blocked outside the water inlet trough 7, avoiding the stones and garbage from clogging the drainage trough 5, and can also reduce the accumulation phenomenon in the drainage channel 3, thereby restoring the drainage capacity of the drainage channel 3. Through the setting of the hinge 9, when the sanitation workers clean the garbage on both sides of the asphalt pavement body 6, they can rotate the entire grille plate 8 to push out the stones and garbage in the gap between the grille plate 8 and the asphalt pavement body 6, so as to facilitate the sanitation workers to clean.

[0030] Reference Figure 4A drainage groove 5 is provided between the curb body 4 and the curb 2, and multiple drainage grooves 5 are arranged at equal intervals. A drainage channel 3 is provided inside the curb 2. The water inlet groove 7, the drainage groove 5 and the drainage channel 3 are all interconnected. Through the coordinated use of the water inlet groove 7, the drainage groove 5 and the drainage channel 3, rainwater can be discharged and the accumulation of rainwater on the asphalt pavement body 6 can be reduced.

[0031] Reference Figure 3 The asphalt pavement body 6 includes: an upper layer 601, a middle layer 602, a permeable layer 603, a lower layer 604, a steel bar construction layer 605, a first crushed stone layer 606, and a second crushed stone layer 607. The middle layer 602 is a porous sound-absorbing material. The middle layer 602 of the porous sound-absorbing material provides the asphalt pavement body 6 with excellent sound absorption performance, which can absorb tire noise on the asphalt pavement body 6, thereby reducing road noise.

[0032] Reference Figure 3 A second crushed stone layer 607 is laid on the top of the roadbed 1, a first crushed stone layer 606 is laid on the side of the second crushed stone layer 607 away from the roadbed 1, a steel bar construction layer 605 is laid on the side of the first crushed stone layer 606 away from the second crushed stone layer 607, a lower layer 604 is laid on the top of the steel bar construction layer 605, a permeable layer 603 is laid on the top of the lower layer 604, a middle layer 602 is laid on the side of the permeable layer 603 away from the lower layer 604, and an upper layer 601 is laid on the top of the middle layer 602.

[0033] Reference Figure 3 The upper layer 601 is an OGFC asphalt mixture, and the lower layer 604 is a densely distributed asphalt mixture. Through the use of OGFC asphalt mixture and densely distributed asphalt mixture, this combination not only meets the road functions of the asphalt pavement body 6, such as high strength, good high and low temperature performance, and smoothness and density, but also realizes the drainage and noise reduction function of the urban road surface.

[0034] Reference Figure 4 A card slot 10 is provided inside the curb body 4 and on one side of the water inlet trough 7. A magnetic block 11 is installed inside the card slot 10. An iron block 12 is fixedly connected to the side of the grille plate 8 away from the hinge 9. The iron block 12 is engaged with the card slot 10. Through the adsorption characteristics of the iron block 12 and the magnetic block 11, the grille plate 8 can be fixed in the corresponding water inlet trough 7, thereby preventing the shaking grille plate 8 from affecting the moving vehicle.

[0035] Reference Figure 1The drainage channel 3 is arranged at an angle as a whole, and a hidden handle is provided at one end of the top of the grille plate 8. The top of the asphalt pavement body 6 is provided with a convex surface to facilitate the flow of rainwater. The drainage channel 3 is arranged at an angle, which can speed up the flow rate of the water in the drainage channel 3 and allow the rainwater to be discharged as quickly as possible. The hidden handle is provided to facilitate the opening and closing of the grille plate 8.

[0036] Working principle: First, on rainy days, rainwater will flow into the water inlet trough 7 along the inclined surface on the asphalt pavement body 6, and then be guided into the drainage channel 3 through the drainage trough 5. The rainwater is discharged uniformly through the drainage channel 3, reducing the accumulation of rainwater on the asphalt pavement body 6, thereby reducing the slippage of vehicles. The inclined setting of the drainage channel 3 can speed up the flow rate of the water in the drainage channel 3, allowing the rainwater to be discharged as quickly as possible. The setting of the grille plate 8 can block stones and garbage mixed in the rainwater outside the water inlet trough 7, preventing stones and garbage from clogging the drainage channel 5, and also reducing the accumulation of rainwater in the drainage channel 3, thereby restoring the drainage capacity of the drainage channel 3.

[0037] By using OGFC asphalt mixture and densely distributed asphalt mixture, this combination not only meets the road functions of the asphalt pavement body 6, such as high strength, good high and low temperature performance, and smoothness and density, but also realizes the drainage and noise reduction function of the urban road. Through the setting of the hinge 9, when the sanitation workers clean the garbage on both sides of the asphalt pavement body 6, the entire grille plate 8 can be rotated to push out the stones and garbage in the gap between the grille plate 8 and the asphalt pavement body 6, so as to facilitate the sanitation workers to clean up. The grille plate 8 can be fixed in the corresponding water inlet trough 7 through the adsorption characteristics of the iron block 12 and the magnetic block 11, thereby preventing the shaking grille plate 8 from affecting the moving vehicles.
