Description

Technical Field

[0001] The utility model relates to the field of pavement, in particular to a pavement crack prevention device. Background Art

[0002] During the road paving construction, in order to make the road surface have sufficient strength and good stability, and its surface meets the requirements of flatness, density and anti-skid, three layers are usually laid up and down, including surface layer, base layer and cushion layer. The surface layer is divided into high-grade surface layer, sub-high-grade surface layer, medium-grade surface layer, low-grade surface layer, etc. The material of the high-grade surface layer is generally cement concrete, asphalt concrete, etc.

[0003] Asphalt concrete is made of a mixture of multiple materials, and the multiple materials react chemically and generate heat, which accumulates in the asphalt concrete surface layer, causing the road surface temperature to rise and dissipate heat slowly. When the climate changes, thermal expansion and contraction reactions are likely to occur, resulting in cracks. In addition, the road surface is paved as a whole. If some foundations collapse slightly, the road surface here will collapse simultaneously, or collapse under the action of external forces, causing deformation of the road surface in other locations, that is, cracks.

[0004] In order to maintain the flatness of the road surface, the road surface with cracks is generally repaired. At present, the road surface repair equipment is generally used to inject the repair material into the crack, and the road surface is repaired through the action of the repair material. There are many devices for road repair, such as a Chinese patent with publication number CN114703731B that discloses a device for repairing road cracks, which includes a body, a transmission rod is rotatably provided at the bottom of the body, a wheel hub is provided at the outer wall fixing sleeve of the transmission rod, a receiving groove is opened at the bottom of the body, a transmission pipe is provided in the receiving groove, grinding discs are provided at both ends of the transmission pipe, a driving structure is provided in the receiving groove for driving the grinding disc to rotate following the rotation of the transmission rod, and a moving structure for driving the grinding disc in and out of the crack is also provided in the receiving groove. An electric push rod is arranged, and when the electric push rod drives the grinding disc to move downward, chain three is tightened, and at the same time, the chain three is driven to move in the direction of the electric push rod, and the spring one generates potential energy. When the electric push rod drives the connecting block one, the rotating rod and the connecting block two to move downward, when the grinding disc touches the bottom, the connecting block two moves away from each other to make the two grinding discs move away from each other and fit the inner wall of the crack.

[0005] The crack repair methods and repair devices described above are only used to repair the road surface after cracks appear, that is, secondary processing in the later stage. Although this method can effectively fill cracks and repair the road surface, it increases the road maintenance cost. At the same time, the road maintenance department will not find the cracks in time after they appear, so the existing cracks will become the cause of accidents, that is, it will cause personal injury.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0027] Example 1

[0028] It is recorded in the background technology that cracks appear in other areas of the existing road surface due to thermal expansion and contraction or collapse of some areas. In order to make the road surface smooth, a road surface repair device is usually used to add repair materials to the cracks. This method increases the road surface maintenance cost, and the cracks are not easy to be discovered in time, so it is easy to cause personal injury. In order to solve the above problems, this embodiment provides a device that can discharge the heat inside the road surface and reduce the impact of thermal expansion and contraction of the road surface. The specific solution is shown below.

[0029] like Figure 1 As shown, the above-mentioned device includes multiple groups of heat-conducting components 4, which are spliced ​​and connected, and are all arranged on the road base 2 and located at the road surface layer 3. In addition, the end of the heat-conducting component 4 can protrude from the road surface or be flush with the road surface, so as to achieve heat transfer through the heat-conducting component 4, and then discharge the heat accumulated inside the road surface, and reduce the influence of thermal expansion and contraction on the road surface. The road surface usually includes a surface layer 3, a base layer 2 and a cushion layer 1 distributed up and down. Since the heat-conducting component 4 is arranged at the surface layer 3, the heat in the surface layer 3 is mainly discharged.

[0030] like Figure 2 As shown, in order to achieve heat conduction, each group of heat-conducting components 4 includes a heat-conducting pipe 5, a connecting pipe 6 and a heat-conducting rod 7, a plurality of heat-conducting pipes 5 are arranged in parallel, a connecting pipe 6 is arranged to connect a plurality of heat-conducting pipes 5, and a plurality of heat-conducting rods 7 are respectively arranged on a plurality of heat-conducting pipes 5. The heat-conducting pipes 5 of two adjacent groups of heat-conducting components 4 are arranged one by one in a positively connected manner, and the end of the heat-conducting pipe 5 located at the edge of the road surface protrudes from the road surface or is flush with the edge of the road surface. The arrangement of the heat-conducting pipe 5 and the heat-conducting rod 7 is convenient for absorbing the heat in the surface layer 3, and the gas can flow inside and outside the heat-conducting pipe 5, so that the heat of the heat-conducting component 4 can be taken away, or the heat-conducting pipe 5 can be made to protrude from the road surface, and under the action of the airflow, the heat of the heat-conducting component 4 can be taken away, so as to realize the external discharge of the heat in the dense layer 3, and avoid the high road surface temperature, which makes it susceptible to the influence of external thermal expansion and contraction. With the cooperation of the connecting pipe 6 and the heat-conducting pipe 5, a plurality of separated spaces are formed, so that the surface layer is divided into a plurality of regions, which will reduce the influence of the adjacent regions and avoid the slight collapse of some regions causing cracks in other regions.

[0031] like Figure 3 As shown, the heat conducting pipe 5 can be set as a square pipe or a round pipe, depending on actual needs, and a first heat conducting hole 51 is set on the side wall of the heat conducting pipe 5, and a heat conducting rod 7 is set at the first heat conducting hole 51, and the heat conducting rod 7 runs through the heat conducting pipe 5. Because the heat conducting rod 7 is connected to the heat conducting pipe 5, heat transfer is achieved by utilizing the heat conduction principle of solid medium.

[0032] like Figure 3 As shown, in order to stably install the heat conducting pipe 5 under the action of the connecting pipe 6, a second heat conducting hole 53 may be further provided on the side wall of the heat conducting pipe 5, and at least two connecting pipes 6 are provided between two adjacent heat conducting pipes 5. The connecting pipe 6 is provided vertically to the heat conducting pipe 5 by welding, and is provided directly opposite to the second heat conducting hole 53. This arrangement allows the connecting pipe 6 to be stably connected to the heat conducting pipe 5, and the heat conducting pipe 5 and the connecting pipe 6 can be used to achieve heat conduction.

[0033] If the cross section of the second heat conducting hole 53 is the same as that of the connecting pipe 6 and their heights are both smaller than the height of the heat conducting pipe 5 , the end of the connecting pipe 6 can extend into the heat conducting pipe 5 , and when the gas flows in and out of the heat conducting pipe 5 , the heat of the connecting pipe 6 can be taken away.

[0034] The cross section of the second heat conducting hole 53 may also be the same as the cross section of the space inside the connecting pipe 6 , and the heights of both holes may be smaller than the height of the heat conducting pipe 5 .

[0035] like Figure 3 , Figure 4 As shown, the connection between the connecting pipe 6 and the heat conducting pipe 5 may also be in other ways, for example, the second heat conducting hole 53 is located at the upper part of the heat conducting pipe 5, and a support frame 52 is provided below the second heat conducting hole 53 and fixedly connected to the heat conducting pipe 5, and plug plates 61 are provided at both ends below the connecting pipe 6, and the plug plates 61 are inserted into the support frame 52. With the cooperation of the plug plates 61 and the support frame 52, the connecting pipe 6 and the heat conducting pipe 5 are stably connected, and only need to be built at the construction site, which improves the building efficiency of the heat conducting assembly 4.

[0036] When using the heat-conducting component 4 , its placement position can be determined according to actual needs, and it is not limited to being placed on the surface layer 3 .

[0037] Example 2

[0038] It is recorded in the background technology that cracks appear in other areas of the existing road surface due to thermal expansion and contraction or collapse of some areas. In order to make the road surface smooth, a road surface repair device is usually used to add repair materials to the cracks. This method increases the road surface maintenance cost, and the cracks are not easy to be discovered in time, so it is easy to cause personal injury. In order to solve the above problems, this embodiment provides a device that can discharge the heat inside the road surface and reduce the impact of thermal expansion and contraction of the road surface. The specific solution is shown below.

[0039] like Figure 1 As shown, the above-mentioned device includes multiple groups of heat-conducting components 4, which are spliced ​​and connected, and are all arranged on the road base 2 and located at the road surface layer 3. In addition, the end of the heat-conducting component 4 can protrude from the road surface or be flush with the road surface, so as to achieve heat transfer through the heat-conducting component 4, and then discharge the heat accumulated inside the road surface, and reduce the influence of thermal expansion and contraction on the road surface. The road surface usually includes a surface layer 3, a base layer 2 and a cushion layer 1 distributed up and down. Since the heat-conducting component 4 is arranged at the surface layer 3, the heat in the surface layer 3 is mainly discharged.

[0040] like Figure 2As shown, in order to achieve heat conduction, each group of heat-conducting components 4 includes a heat-conducting pipe 5, a connecting pipe 6 and a heat-conducting rod 7, a plurality of heat-conducting pipes 5 are arranged in parallel, a connecting pipe 6 is arranged to connect a plurality of heat-conducting pipes 5, and a plurality of heat-conducting rods 7 are respectively arranged on a plurality of heat-conducting pipes 5. The heat-conducting pipes 5 of two adjacent groups of heat-conducting components 4 are arranged one by one in a positively connected manner, and the end of the heat-conducting pipe 5 located at the edge of the road surface protrudes from the road surface or is flush with the edge of the road surface. The arrangement of the heat-conducting pipe 5 and the heat-conducting rod 7 is convenient for absorbing the heat in the surface layer 3, and the gas can flow inside and outside the heat-conducting pipe 5, so that the heat of the heat-conducting component 4 can be taken away, or the heat-conducting pipe 5 can be made to protrude from the road surface, and under the action of the airflow, the heat of the heat-conducting component 4 can be taken away, so as to realize the external discharge of the heat in the dense layer 3, and avoid the high road surface temperature, which makes it susceptible to the influence of external thermal expansion and contraction. With the cooperation of the connecting pipe 6 and the heat-conducting pipe 5, a plurality of separated spaces are formed, so that the surface layer is divided into a plurality of regions, which will reduce the influence of the adjacent regions and avoid the slight collapse of some regions causing cracks in other regions.

[0041] like Figure 3 As shown, the heat conducting pipe 5 can be set as a square pipe or a round pipe, depending on actual needs, and a first heat conducting hole 51 is set on the side wall of the heat conducting pipe 5, and a heat conducting rod 7 is set at the first heat conducting hole 51, and the heat conducting rod 7 runs through the heat conducting pipe 5. Because the heat conducting rod 7 is connected to the heat conducting pipe 5, heat transfer is achieved by utilizing the heat conduction principle of solid medium.

[0042] like Figure 5 , Figure 6 , Figure 7 As shown, in order to stably install the heat conducting tube 5 under the action of the connecting tube 6, a through hole 54 is provided at the bottom of the heat conducting tube 5, and the through hole 54 is arranged obliquely relative to the heat conducting tube 5. Two through holes 54 are arranged on the same heat conducting tube 5, and the two through holes 54 are arranged in an "eight" structure. The positions of the through holes 54 on the multiple heat conducting tubes 5 are all different. Each group of heat conducting components 4 includes two connecting tubes 6, and the same connecting tube 6 penetrates the through holes 54 of the multiple heat conducting tubes 5. The connecting tube 6 is provided with multiple baffles 62, and the multiple baffles 62 are respectively arranged adjacent to the multiple heat conducting tubes 5. Because the through holes 54 are arranged obliquely, and the positions of the through holes 54 on the multiple heat conducting tubes 5 are different, when the through holes 54 of the multiple heat conducting tubes 5 are arranged on the same straight line, the connecting tube 6 can penetrate the multiple heat conducting tubes 5 at the same time. After installing two connecting tubes 6, the relative positions of the multiple heat conducting tubes 5 can be limited, so that they are stably connected. The provision of the baffle 62 enhances the strength of the connection between the heat conducting pipe 5 and the connecting pipe 6 .

[0043] When using the heat-conducting component 4 , its placement position can be determined according to actual needs, and it is not limited to being placed on the surface layer 3 .
