Description

Technical Field

[0001] The utility model relates to the technical field of pavement structures, and more specifically, to a pavement anti-cracking structure. Background Art

[0002] The road surface usually refers to a layered structure paved with road-building materials, which can make vehicles run more smoothly.

[0003] Publication No. CN216141824U discloses an anti-cracking composite pavement structure, whose technical solution includes a subbase, a reinforced base and a surface layer laid in sequence from bottom to top, wherein the surface layer is fixed to the reinforced base by adhesive; the reinforced base is composed of more than one reinforced structure layer, and the reinforced structure layer includes a geocell filled with filler inside and a geotextile on the top.

[0004] The above technical solution reduces the impact of cracks and uneven deformation of the roadbed on the road surface by laying a reinforced base between the surface layer and the subbase. At the same time, the geotextile in the reinforced base can absorb stress and reduce cracks, thereby improving the bearing capacity and fatigue resistance of the road surface. However, the above technical solution only reduces the occurrence of cracks by adding geotextile to the reinforced base. But when the weather is hot, the high temperature outside will expose the road surface, causing the road surface to expand due to the heat, and then causing the road surface to crack, affecting the service life of the road surface.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a road surface anti-cracking structure, which solves the problem that when the weather is hot, the high temperature outside will expose the road surface, causing the road surface to expand due to the heat, and then causing the road surface to crack, thereby affecting the service life of the road surface.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a pavement anti-cracking structure, including a pavement body, the pavement body including a base layer and a surface layer, a plurality of water pipes are fixedly connected in the surface layer, a plurality of placement grooves are opened on the surface layer, a plurality of placement grooves are provided with nozzles, the nozzles are fixedly connected to the side walls of the water pipes, a spraying assembly for spraying water onto the surface layer is provided on the placement groove, and a waterproof layer is provided between the base layer and the surface layer.

[0008] By adopting the above technical scheme, when the weather is hot, water is transported to the nozzle through the water pipe, and the nozzle is used to spray water into the spray assembly. The water can be sprayed above the surface through the spray assembly. The water sprayed above the surface can absorb the heat of the surface, so as to achieve the effect of cooling the road surface, avoid the road surface expansion caused by heat, and then cause the road surface to crack, thereby increasing the service life of the road surface. At the same time, through the provision of a waterproof layer, it can prevent unevaporated water from contacting with the base layer, causing erosion of the base layer, thereby increasing the service life of the road surface. The surface layer is made of recycled asphalt, which can recycle and reuse waste asphalt to improve its utilization value.

[0009] The utility model is further configured as follows: the spray assembly includes a movable plate slidably connected to the side wall of the placement groove, the side wall of the movable plate is provided with a plurality of water outlet holes which are interconnected, a fixed plate is fixedly connected in the placement groove, the spray head penetrates to the top of the fixed plate, a bellows is sleeved on the spray head, one end of the bellows is fixedly connected to the fixed plate, the other end penetrates to the water outlet hole and is fixedly connected to the movable plate, and the fixed plate and the movable plate are connected by an elastic member.

[0010] By adopting the above technical scheme, when it is necessary to spray the surface, water is transported to the nozzle through the water pipe, and the nozzle is used to spray the water into the corrugated pipe, and the water is transported to the water outlet hole of the movable plate through the corrugated pipe, so that the water is sprayed onto the surface through the water outlet hole, thereby achieving the effect of spraying water onto the surface. At the same time, through the setting of the elastic part, when the vehicle is driving, the movable plate can enter the placement groove to prevent the vehicle from being affected by the movable plate and being bumped.

[0011] The utility model is further configured as follows: the elastic member comprises a spring sleeved on the bellows, the two ends of the spring are respectively connected to the fixed plate and the movable plate, and when the spring is in a natural state, the bottom surface of the movable plate is in the same horizontal plane as the surface layer.

[0012] By adopting the above technical solution, when the vehicle drives over the movable plate, the movable plate begins to move downward along the side wall of the placement groove due to the influence of the vehicle's weight, and at the same time drives the spring to deform and compress. When the vehicle drives away from the movable plate, the spring loses its restriction and begins to deform and recover, and drives the movable plate back to its original position, thereby preventing the vehicle from shaking when driving.

[0013] The utility model is further configured as follows: a mortar layer is provided between the surface layer and the waterproof layer, the mortar layer is in contact with the bottom of the surface layer, and a support member for strengthening the structural strength between the surface layer and the waterproof layer is provided in the mortar layer.

[0014] By adopting the above technical solution, when water is sprayed above the surface, the water that has not been evaporated will begin to penetrate downward through the surface. At this time, the mortar layer can be set to absorb the water that penetrates downward, so that the mortar layer is in a moist state. The mortar layer in a moist state can extend the cooling effect of water on the surface. At the same time, the support can be set to improve the structural strength between the surface and the waterproof layer, thereby preventing the road surface from being dented due to external influences.

[0015] The utility model is further configured as follows: the support member includes a plurality of support rods, the two ends of the plurality of support rods are respectively fixedly connected to the surface layer and the waterproof layer, two fixing rods are fixedly connected between two adjacent support rods, and the two fixing rods are cross-arranged.

[0016] By adopting the above technical solution and setting a number of support rods, the structural strength between the surface layer and the waterproof layer can be improved. At the same time, by setting a number of fixing rods, the surface layer can be prevented from denting, thereby increasing the service life of the road surface.

[0017] The utility model is further configured as follows: a fixed net is fixedly connected to the bottom of the surface layer.

[0018] By adopting the above technical solution, the structural strength of the surface layer can be further improved, the problem of cracking of the surface layer can be prevented, and the service life of the road surface can be increased.

[0019] In summary, the utility model has the following beneficial effects: when the weather is hot, water is sprayed into the spray assembly by means of a nozzle, and the water can be sprayed above the surface through the spray assembly, and the water sprayed above the surface can absorb the heat of the surface, thereby achieving the effect of cooling the road surface, avoiding the road surface from expanding due to heat, which in turn causes the road surface to crack, thereby increasing the service life of the road surface, and at the same time, through the provision of a waterproof layer, it is possible to prevent unevaporated water from contacting the base layer, causing erosion of the base layer, thereby increasing the service life of the road surface, and the surface layer is made of recycled asphalt, which can recycle and reuse waste asphalt to increase its utilization value.
