[0002] Pavement refers to a layered structure paved on the roadbed with various road construction materials that directly bears vehicle loads, facilitating the passage of vehicles and people's daily lives.
[0003] When it rains, due to the limited drainage effect of the road surface, the accumulated water on the road surface will penetrate into the cushion layer, and the cushion layer is usually laid on the surface of the soil. When the accumulated water seeps into the bottom of the road surface, the soil under the base layer will loosen, resulting in unstable overall structural strength of the road surface, which will lead to unstable road structure and insufficient road strength. In order to solve the problem of accumulated water penetrating into the cushion layer, the existing technology is to establish a road drainage channel to drain the accumulated water on the road surface in time, thereby reducing the accumulation of large amounts of accumulated water on the road surface. However, as the road surface is used for a long time, the road surface will crack, so a large amount of accumulated water will still seep into the bottom of the road surface, which will lead to unstable road structure and insufficient road strength.
[0004] Therefore, it is particularly important to design a high-strength pavement structure to solve the above-mentioned defects. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model designs a high-strength pavement structure, which aims to solve the technical problem that when it rains, the pavement drainage effect is limited and the accumulated water on the pavement will penetrate into the cushion layer, resulting in an unstable pavement structure and insufficient pavement strength.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

At the same time, when the pavement body is in use, through the design of multiple groups of deformation grooves, the damage caused by deformation is reduced, the pavement structure is avoided from being damaged, and the strength and service life of the pavement structure can be effectively improved.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] Example:
[0026] See also Figure 1-Figure 6 , the utility model provides a technical solution:
[0027] A high-strength pavement structure includes a pavement body 1, with drainage channels 2 on both sides of the pavement body 1, shoulders 3 on the outsides of the two groups of drainage channels 2, multiple groups of drainage pipes 4 on the inside of the pavement body 1, multiple groups of drainage grooves 5 on the top of the drainage channels 2, drainage covers 6 installed on the outsides of the multiple groups of drainage grooves 5, a first filter screen 7 fixedly installed at the bottom of the drainage groove 5, and a dredging mechanism 8 installed inside the drainage groove 5 and between the drainage cover 6 and the first filter screen 7.
[0028] First, the pavement body 1 is composed of a crushed stone base layer 101, a reinforced concrete layer 102, an upper base layer 103 and a surface layer 104 from bottom to top. The upper base layer 103 is asphalt, and the surface layer 104 is permeable asphalt. The surface of the upper base layer 103 is arc-shaped, and multiple groups of deformation grooves 105 are provided on the inner sides of the upper base layer 103 and the surface layer 104. The pavement body 1 composed of the crushed stone base layer 101, the reinforced concrete layer 102, the upper base layer 103 and the surface layer 104, while ensuring the basic permeability function, the arc-shaped upper base layer 103 can quickly guide the surface of the pavement body 1 into the drainage channels 2 on both sides, thereby avoiding water accumulation in the pavement body 1 and causing continuous infiltration of the accumulated water. At the same time, when the pavement body 1 is in use, the design of multiple groups of deformation grooves 105 can reduce the damage when deformation occurs, avoid damage to the pavement structure, and thus effectively improve the strength and service life of the pavement structure.
[0029] Furthermore, a first connecting groove 201 is opened on the side of the drainage channel 2 close to the reinforced concrete layer 102, and the drainage channel 2 and the shoulder 3 are bonded by cement 202. A second connecting groove 203 is opened on the side opposite to the shoulder 3. Through the design of the first connecting groove 201 and the second connecting groove 203, when the reinforced concrete layer 102 and cement 202 are poured, they can penetrate into the first connecting groove 201 and the second connecting groove 203 to improve the connection strength.
[0030] Then, a second filter net 401 is installed at the top of each of the multiple groups of drainage pipes 4, and the bottom ends of the multiple groups of drainage pipes 4 are fixedly connected to the drainage channel 2. While guiding the accumulated water on the road surface into the drainage channel 2, the multiple groups of drainage pipes 4 assist in drainage, thereby further improving the drainage effect of the pavement body 1, thereby discharging the accumulated water on the road surface in time to avoid the infiltration of accumulated water and affecting the strength of the pavement structure. At the same time, the second filter net 401 is used to filter impurities in the accumulated water during drainage to avoid clogging of the drainage pipe 4.
[0031] Furthermore, multiple sets of drainage vertical grooves 601 are provided at the front ends of the multiple sets of drainage covers 6, multiple sets of drainage holes 602 are provided at the rear ends of the multiple sets of drainage covers 6, and mounting grooves 603 are provided at the front and rear ends of the top of the drainage groove 5. The front and rear ends of the drainage cover 6 are mounted on the inner side of the mounting groove 603. When the accumulated water on the road is introduced into the drainage groove 5, the accumulated water is introduced into the interior of the drainage groove 5 through the multiple sets of drainage vertical grooves 601 and the multiple sets of drainage holes 602. The drainage cover 6 is mounted in the mounting groove 603, which facilitates the disassembly and assembly of the drainage cover 6.
[0032] Secondly, the dredging mechanism 8 includes a partition 801 fixedly installed at the rear end of the drainage trough 5, a water guide groove 802 is opened inside the drainage trough 5 and on the back side of the partition 801, two groups of dredging shafts 803 are rotatably connected inside the drainage trough 5 and in front of the partition 801, and a driving shaft 804 is rotatably connected between the two groups of dredging shafts 803. The accumulated water is discharged into the inner side of the drainage trough 5 through the vertical drainage groove 601 and can be drained quickly. However, the accumulated water will carry more impurities due to the too fast discharge and cause the first filter screen 7 to be blocked. After the water flow entering through the multiple groups of drainage holes 602 enters the interior of the drainage trough 5, it quickly flushes the surface of the first filter screen 7 under the guidance of the water guide groove 802, thereby avoiding the blockage of the first filter screen 7 and improving the drainage effect.
[0033] Finally, multiple groups of dredging rods 805 are fixedly connected to the outer sides of the two groups of dredging shafts 803, and multiple groups of force plates 806 are fixedly connected to the outer sides of the driving shaft 804. The accumulated water can be quickly drained by being discharged into the inner side of the drainage ditch 5 through the drainage vertical groove 601. However, since the accumulated water is discharged too quickly, it will also carry larger debris and cause blockage of the drainage vertical groove 601. When the accumulated water is discharged into the inner side of the drainage ditch 5 through the drainage vertical groove 601, the accumulated water impacts the multiple groups of force plates 806 and can drive the driving shaft 804 to rotate. When the driving shaft 804 rotates, the multiple groups of dredging rods 805 are swung through the multiple groups of force plates 806, thereby driving the dredging shaft 803 to rotate, and the multiple groups of dredging rods 805 are used to pass through the inner side of the drainage vertical groove 601 for dredging, thereby effectively avoiding blockage caused by larger debris, further ensuring the drainage effect of the drainage ditch 5, and then timely draining the road surface water to avoid the infiltration of accumulated water and affecting the strength of the road surface structure.
[0034] In this embodiment, the implementation scenario is specifically as follows: when the pavement structure is in use, the pavement body 1 composed of the crushed stone subbase 101, the reinforced concrete layer 102, the upper base 103 and the surface layer 104, while ensuring the basic water permeability function, the arc-shaped upper base 103 can quickly guide the surface of the pavement body 1 into the drainage channels 2 on both sides, thereby avoiding the accumulation of water in the pavement body 1 and causing continuous infiltration of the accumulated water. At the same time, when the pavement body 1 is in use, through the design of multiple groups of deformation grooves 105, the damage suffered when encountering deformation is reduced, and the pavement structure is avoided from being damaged, thereby effectively improving the strength and service life of the pavement structure. While guiding the accumulated water on the road surface into the drainage channel 2, multiple groups of drainage pipes 4 are used to assist drainage, further improving the drainage effect of the pavement body 1, thereby timely discharging the accumulated water on the road surface, avoiding the infiltration of accumulated water and affecting the strength of the pavement structure. When the accumulated water on the road surface is guided to the drainage groove 5, the accumulated water is guided into the interior of the drainage groove 5 through multiple groups of drainage vertical grooves 601 and multiple groups of drainage holes 602, and the accumulated water passes through the drainage vertical grooves 601. The inner side of the drainage groove 5 can be quickly drained, and after the water flows in through the multiple sets of drainage holes 602 and enters the interior of the drainage groove 5, it quickly washes the surface of the first filter screen 7 under the guidance of the water guide groove 802, thereby avoiding the blockage of the first filter screen 7 and improving the drainage effect. When the accumulated water is discharged into the inner side of the drainage groove 5 through the drainage vertical groove 601, the accumulated water impacts the multiple sets of force plates 806 to drive the driving shaft 804 to rotate. When the driving shaft 804 rotates, the multiple sets of dredging rods 805 are swung through the multiple sets of force plates 806, thereby driving the dredging shaft 803 to rotate, and the multiple sets of dredging rods 805 are used to pass through the inner side of the drainage vertical groove 601 for dredging, thereby effectively avoiding blockage caused by larger debris, further ensuring the drainage effect of the drainage groove 5, and the whole operation process is simple and convenient. Compared with the existing pavement structure, the utility model reduces the damage to the pavement structure when it encounters deformation through design, avoids damage to the pavement structure, and can discharge the accumulated water on the road in time, thereby effectively improving the strength and service life of the pavement structure.
