Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to an anti-skid pavement for a highway. Background Art

[0002] Highway pavement refers to the layered structure paved within the carriageway range on the highway roadbed. With the development of my country's transportation, the structure of highway pavement is also constantly changing. Expressways are high-grade highways, which are a type of highway specially designed for cars to travel at high speeds in separate lanes and with full access control. Although different countries have different names for expressways, they all refer to highways with more than 4 lanes, separated driving in two directions, fully controlled entrances and exits, and all use grade separations. Generally speaking, expressways can adapt to speeds of 120 kilometers per hour or higher, the road surface has a width of more than 4 lanes, a dividing strip is set in the middle, and a high-grade asphalt concrete or cement concrete pavement is used, with complete signs, markings, signals and lighting devices.

[0003] Since vehicles on highways have a high driving speed, in order to increase the anti-skid properties of these special sections and reduce the occurrence of road traffic accidents on the sloped and curved sections of the highway, the road surface is generally designed with an anti-skid structure. In order to facilitate the later maintenance of the road surface, the existing anti-skid structures mostly adopt a slot-embedded installation structure. When the pad strip is pressed down by the vehicle tire, due to the lack of lateral fastening, the pad strip is prone to loosening and shaking in the installation slot, and is prone to detachment and falling after long-term work. Therefore, an anti-skid road surface for highways is proposed. Utility Model Content

[0024] Example

[0025] See also Figure 1-5 The utility model provides a technical solution: an anti-skid road surface of a highway, comprising: a road base layer 1, a gravel layer 2, an asphalt layer 3 and an anti-skid mechanism 4, the road base layer 1, the gravel layer 2 and the asphalt layer 3 are laid and distributed in sequence, the road base layer 1 is constructed by compacting a soil layer, and serves as a supporting structure of the road surface, such as the attached Figure 1 As shown, a gravel layer 2 is laid on the upper part of the road base layer 1. The gravel layer 2 is laid by sand particles and compacted, and has good drainage. An asphalt layer 3 is laid on the upper part of the gravel layer 2. The asphalt layer 3 is laid by asphalt.

[0026] The anti-skid mechanism 4 is installed on the upper part of the asphalt layer 3. The anti-skid mechanism 4 includes an anti-skid pad 6. The anti-skid pad 6 is made of rubber. In order to facilitate the installation and connection of the anti-skid pad 6, an installation groove 5 is provided on the upper part of the asphalt layer 3. The installation groove 5 is provided with multiple grooves, such as the attached Figure 3As shown, a plurality of mounting grooves 5 are evenly and equidistantly opened on the upper part of the asphalt layer 3, the mounting grooves 5 are matched with the anti-skid pads 6, and the anti-skid pads 6 are embedded and installed inside the mounting grooves 5, and the anti-skid pads 6 are embedded and installed on the upper part of the asphalt layer 3 through the mounting grooves 5 at an equal distance.

[0027] To facilitate the installation and fixation of the anti-slip pad 6, a mounting screw hole 8 is provided in the middle of the anti-slip pad 6, and a mounting bolt is provided inside the mounting screw hole 8. The anti-slip pad 6 is fixed to the inside of the mounting groove 5 by the mounting bolt. The slotted installation does not require a specific mounting structure and is convenient for disassembly and assembly. To improve the installation stability of the mounting bolts, fixed spacers 7 are evenly provided in the middle of the anti-slip pad 6, and the mounting screw hole 8 is opened through the middle of the fixed spacer 7. The fixed spacer 7 can provide stable fastening support for the mounting bolt.

[0028] In order to improve the installation stability of the anti-skid pad 6, an arc-shaped clip 9 is provided in the middle of the lower side of the anti-skid pad 6. The arc-shaped clip 9 is an arc-shaped steel clip with good support and deformation rebound characteristics. A plurality of arc-shaped clips 9 are provided, and several arc-shaped clips 9 are evenly fixed and embedded in the middle of the bottom side of the anti-skid pad 6 in an equidistant shape. The arc-shaped clip 9 is located between two adjacent fixed spacers 7. When the middle part of the anti-skid pad 6 is pressed down by the tire, the impact is absorbed by the deformation of the arc-shaped clip 9, and the arc-shaped clip 9 is used to absorb the impact. The deformation expansion allows the lower side of the anti-skid pad 6 to be close to the inner side wall of the installation groove 5. While absorbing the impact, the anti-skid pad 6 can be stably supported inside the installation groove 5 by pressing and limiting, which greatly improves the installation stability of the anti-skid pad 6. In order to improve the drainage characteristics of the anti-skid pad 6, water guiding grooves 10 are evenly arranged on the upper part of the anti-skid pad 6. The water guiding grooves 10 penetrate the upper part of the anti-skid pad 6 horizontally. Rainwater can be quickly guided and gathered into the drainage groove on the side of the road surface through the water guiding grooves 10.

[0029] The working principle or structural principle is that during installation, an installation groove 5 is opened on the upper part of the highway road surface, and then the anti-skid pad 6 is installed into the inside of the installation groove 5 by fitting, and then the mounting bolts are installed into the inside of the mounting screw holes 8 in sequence, and the installation and fixing of the anti-skid pad 6 is completed by tightening. When the vehicle passes by, the contact between the anti-skid pad 6 and the tire can increase the friction of the vehicle tire to prevent the vehicle from driving slip. When the tire presses down on the anti-skid pad 6, the anti-skid pad 6 is subjected to the downward pressure, causing the lower arc-shaped clip 9 to expand and deform, thereby absorbing and buffering the impact of the tire, and when the arc-shaped clip 9 expands and deforms, the lower two sides of the anti-skid pad 6 are pressed against the inner side of the installation groove 5 through expansion and extrusion, and while absorbing the impact, the anti-skid pad 6 can be stably supported in the inside of the installation groove 5 by compression and limiting.

[0030] In summary, the anti-skid pavement adopts a pad-type anti-skid structure, and utilizes the installation groove 5 arranged on the upper part of the asphalt layer 3 to install and connect the anti-skid pad 6. The slotted installation does not require a specific installation structure, which is convenient for disassembly and assembly, and an arc-shaped clip 9 is arranged on the lower supporting side of the anti-skid pad 6. When the middle part of the anti-skid pad 6 is pressed down by the tire, the impact is absorbed by the deformation of the arc-shaped clip 9, and the deformation expansion of the arc-shaped clip 9 allows the lower side of the anti-skid pad 6 to be close to the inner side wall of the installation groove 5. While absorbing the impact, the anti-skid pad 6 can be stably supported inside the installation groove 5 by pressing and limiting, thereby greatly improving the installation stability of the anti-skid pad 6.
