By adopting the above technical solution, the present invention has the following advantages compared with the existing technology:

The present invention lays an adhesive layer, a mesh layer, a crushed stone layer and a steel grid from top to bottom in sequence between the surface layer and the foundation, and utilizes the viscosity of the adhesive layer, the anti-deformation effect of the mesh layer, the support effect of the crushed stone layer and the steel grid, and the drainage effect of the steel grid to greatly improve the high-strength support stability of the entire pavement structure and the use effect of the pavement.

At the same time, the sand always generates a downward falling impulse due to the gravity when the leveling roller rolls, so that the center of gravity of the entire force is kept in the center position. In this way, the pressure of the leveling roller when rolling the road surface is more balanced and uniform, which can improve the stability and efficiency of the leveling work.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

As shown in Figures 1-5, the present invention provides a technical solution for a rutting-resistant pavement structure and a pavement leveling device: the rutting-resistant pavement structure includes a foundation 1 and a surface layer 2 laid on the upper side, an adhesive layer 3, a mesh layer 4 and a crushed stone layer 5 are laid in sequence from top to bottom between the surface layer 2 and the foundation 1, a steel grid 6 is provided on the upper side of the foundation 1, and the crushed stone layer 5 is filled and arranged on the upper side of the steel grid 6. First, the steel grid 6 is laid on the foundation 1. The steel grid 6, as a reinforcing steel material, can effectively enhance the overall stability of the road surface, prevent the road surface from sinking and deformation caused by vehicle loads, and improve the overall support. Then, the crushed stone layer 5 is laid on the steel grid 6. The crushed stone layer 5 is composed of crushed stones of different sizes, which are compacted to form a stable structure and can be evenly distributed. The load transmitted from the upper part of the cloth, these gravel parts can fall into the hollow parts of each steel grid 6 and combine to form a whole, provide additional support, and enhance the overall stability of the road surface; and the mesh layer 4 is composed of a high-strength fiber mesh or metal mesh, its function is to enhance the bearing capacity and crack resistance of the road surface, can disperse the vehicle load, and act on the gravel layer 5 and the steel grid 6, reduce the direct pressure on the road surface to cause cracking, and extend the service life of the road surface. An adhesive layer 3 is arranged on the upper side of the mesh layer 4. The adhesive layer 3 is usually made of modified asphalt, which firmly bonds the materials of the surface layer 2 together, ensures the integrity and stability of the entire road surface structure, and combined with the characteristics of the lower mesh layer 4, has a good compressive resistance.

The road leveling equipment is used for rolling rutting-resistant road surface structures. The road leveling equipment includes a rolling vehicle 7. A movable platform 8 is rotatably installed at the front end of the rolling vehicle 7. A leveling roller 9 for rolling the road surface is installed at the bottom of the movable platform 8. A movable groove 100 is opened on the upper side of the movable platform 8. A connecting block 101 is slidably arranged in the movable groove 100. Since a telescopic rod 10 is rotatably installed on the upper side of the rolling vehicle 7, the telescopic rod 10 can adopt a hydraulic telescopic rod in the prior art. The telescopic rod 10 can be installed, and the telescopic end of the pressure telescopic rod 10 is rotatably connected to the connecting block 101. A plurality of reset springs 103 connected to the bottom of the movable groove 100 are installed at the bottom of the connecting block 101. An outer convex edge 102 is opened on the outer side of the connecting block 101 and is clamped in the notch of the movable groove 100, so that the telescopic rod 10 pulls the movable platform upward. When the movable platform 8 is lowered, the outer convex edge 102 is clamped on the notch of the movable groove 100, so that the leveling roller 9 can be lifted to a certain horizontal height, thereby adjusting the contact state between the leveling roller 9 and the road surface, which is not only convenient for transportation, but also the height adjustment can be applied to the rolling of roads at different heights, and has good applicability. The telescopic rod 10 pushes the movable platform 8 downward to lower the movable platform 8, so that the leveling roller 9 at the bottom of the movable platform 8 can contact the road surface. When the telescopic rod 10 continues to extend downward, the connecting block 101 slides downward and pushes the movable platform 8 through the return spring 103. The elastic force of the return spring 103 can avoid excessive push causing greater connection wear, so that the rolling of the leveling roller 9 on the road surface has a certain elastic stress, which can adapt to the unevenness of the road surface to a certain extent and improve the uniformity and effect of rolling.

Secondly, a double counterweight method is specifically set up, one of which is for the counterweight adjustment of the leveling roller 9. Specifically, a counterweight inner cavity 90 is provided on the inner side of the leveling roller 9, and discharge valves 91 connected to the counterweight inner cavity 90 are respectively arranged in a circular manner on both sides of the leveling roller 9. A first spiral blade rod 92 is rotatably arranged in the middle of the leveling roller 9. Both ends of the first spiral blade rod 92 pass through both sides of the leveling roller 9 and are rotatably connected to the movable platform 8. Both ends of the first spiral blade rod 92 are rotatably connected to the leveling roller 9 through bearings to reduce the rotation between them. Another advantage of this arrangement is that the flattening roller 9 can rotate on the first spiral blade rod 92, and the first spiral blade rod 92 can also rotate according to the use control to control the conveying of the counterweight sand, wherein the first spiral blade rod 92 is provided with an inner feeding cavity 93 from the middle of the right end inward, and the surface of the first spiral blade rod 92 is provided with a plurality of discharge ports 94 connected to the inner feeding cavity 93, and a feeding mechanism for feeding the inner feeding cavity 93 is provided on one side of the movable table 8, so that the feeding mechanism can feed the counterweight sand The sand is fed into the inner feeding cavity 93 of the first spiral blade rod 92 and falls into the inner side of the counterweight inner cavity 90 through each discharge port 94, thereby increasing the rolling gravity of the leveling roller 9. The rotors on both sides of the first spiral blade rod 92 of the counterweight inner cavity 90 are arranged relatively to each other. A first driving motor 96 for driving the first spiral blade rod 92 to rotate is installed on the left side of the movable platform 8. Therefore, when the first driving motor 96 drives the first spiral blade rod 92 to rotate, the rotors symmetrical on both sides can synchronously push the sand scattered on both sides of the counterweight inner cavity 90 to the middle part for transportation. The center of gravity of the entire force is kept in the middle of the leveling roller 9. When the leveling roller 9 rolls the road surface, the gravity of the sand makes the pressure of the leveling roller 9 rotating to roll the road surface more balanced and uniform. When it is necessary to reduce the internal counterweight sand, the six discharge valves 91 on both sides of the leveling roller 9 are opened, and then the first spiral blade rod 92 rotates in the opposite direction, so that the symmetrical rotors synchronously transport the counterweight sand to both sides, and the sand is discharged outward from the opened discharge valve 91, and then the weight is re-balanced according to the needs. It is simple and convenient to use, and the structure is ingenious and compact.

Another way is to counterweight the movable platform 8. A counterweight screw 81 is vertically installed on the upper side of the movable platform 8. The counterweight screw 81 is threaded with multiple counterweight weights 82. The weight of the movable platform 8 can be increased or decreased by increasing or decreasing the number of counterweight weights 82 on the counterweight screw 81. Combined with the first way of counterweighting the leveling roller 9 mentioned above, a double pressure effect is achieved, thereby improving the rolling effect. The elastic pushing force of the telescopic rod 10 is used to combine the counterweight of the movable platform 8 and the counterweight of the leveling roller 9 to synchronously pressurize the road surface, which is more conducive to the rolling and leveling effect and efficiency.

Among them, in order to better realize the feeding of the inner feeding cavity 93 of the first spiral blade rod 92, the feeding mechanism includes a sand box 11 installed on one side of the movable table 8, the right axial end of the first spiral blade rod 92 extends to one side of the sand box 11, and a second spiral blade rod 111 is installed on the inner side of the sand box 11, and the left end of the second spiral blade rod 111 is rotated to insert into the inner side of the inner feeding cavity 93, so that the second spiral blade rod 111 can continuously supply the counterweight sand while the rotor of the second spiral blade rod 111 rotates to transport the counterweight sand to the middle part, and the counterweight sand is continuously supplied to the inner feeding cavity 93. The counterweight sand in the heavy inner cavity 90 is also not easy to flow back to the inner feeding cavity 93, ensuring the effect of sustainable feeding. A second driving motor 112 is installed on the outside of the sand box 11 to drive the second spiral blade rod 111 to rotate. When the sand box 11 is in use, the counterweight sand measured externally needs to be poured in, and then the second driving motor 112 drives the second spiral blade rod 111 to be directly fed into the inner feeding cavity 93, and enters the counterweight inner cavity 90 through various discharge ports 94 connected to the outside of the inner feeding cavity 93, thereby realizing centralized feeding and simultaneous feeding.

In addition, a support spring 83 is connected to the side opposite to the movable platform 8 of the roller trolley 7. The support spring 83 is a connection method of screw detachment, and the movable platform 8 can be pushed out of the telescopic rod 10, as shown in Figure 3. When the leveling roller 9 of the movable platform 8 rolls the road surface, the support spring 83 is installed. This structure utilizes the support spring 83 to further provide elastic support for the movable platform 8, rather than relying solely on the elastic support of the reset spring 103 and the gravity of the leveling roller 9 and the movable platform 8 to achieve rolling, thereby further improving the effect of elastic rolling.

Furthermore, an arc-shaped scraper 14 is elastically and tightly attached to the upper side of the leveling roller 9. The arc-shaped scraper 14 includes an arc-shaped outer frame 141, an inner side of which is fixedly provided with an arc-shaped inner net 142. The arc-shaped outer frame 141 and the arc-shaped inner net 142 are made of metal material. The arc-shaped outer frame 141 and the arc-shaped inner net 142 are both tightly attached to the upper side of the leveling roller 9. A plurality of elastic bands 143 are respectively fixed on the left sides of the arc-shaped outer frame 141, and are fastened to the movable platform 8 through the elastic bands 143. By elastically attaching the arc-shaped scraper 14 to the upper side of the leveling roller 9, the elastic force is utilized to always keep the leveling roller 9 in close contact with the leveling roller 9. Compared with the existing one, the arc-shaped outer frame 141 can scrape away the mud impurities adhered to the surface of the leveling roller 9 when the leveling roller 9 rotates, and the arc-shaped inner net 142 has a plurality of mesh holes. Some of the soil impurities will be scraped away again by the arc-shaped inner net 142, and the movable platform 8 is equipped with a connecting pipe 12, and the connecting pipe 12 is equipped with multiple air pressure nozzles 13, and each air pressure nozzle 13 corresponds to the top of the leveling roller 9 respectively. An air pump 71 is installed on one side of the movable platform 8 and is connected to the connecting pipe 12 through a soft air pipe. Each air pressure nozzle 13 is located above the arc-shaped inner net 142. Therefore, through the action of the air pump 71, each air pressure nozzle 13 generates high-pressure gas and blows it to the mesh holes of the arc-shaped inner net 142, and directly blows the soil on the surface of the leveling roller 9 through some of the mesh holes. The soil will be blown and the arc-shaped inner net 142 can be scraped off better, and the soil impurities on the arc-shaped inner net 142 are also easily blown off, which is beneficial to maintaining the flatness of the surface of the leveling roller 9, which is beneficial to the drying effect of the leveling roller 9 and improves the rolling effect.

Furthermore, it is designed that the front and rear ends of the arc-shaped outer frame 141 are respectively provided with sharp corners, and are closely attached to the side of the leveling roller 9 , so that the sharp corner design can make it easier to scrape off soil impurities.

It should be noted that the anti-rutting pavement structure of the present invention mainly improves the above-mentioned structure, and the functions, components and structures not mentioned therein can be implemented by using components and structures in the prior art that can achieve corresponding functions.

The present invention has been described in detail above through specific embodiments, but these do not constitute limitations of the present invention. Without departing from the principle of the present invention, those skilled in the art may also make many variations and improvements, which should also be regarded as the protection scope of the present invention.
