[0004] The comparatively better ratio has achieved the effect of heat insulation and increased the stability of the road surface. However, when laying filter pavement on cement roads in villages, it is often laid directly on the original road surface due to cost. After paving, the two sides of the asphalt pavement are likely to be higher than the road surface used by residents on both sides of the road surface, and it lacks functions such as limiting and water diversion, and is easily deformed and water-logged under temperature and heavy pressure.

[0005] In summary, the present invention provides a temperature-insulating asphalt pavement structure to solve the above problems. Utility Model Content

The diversion unit includes a bottom plate, and an inclined frame is provided on the top of the bottom plate.

[0008] Furthermore, in the present invention, the pavement unit also includes filter oil, which is sprayed on the top of the road base body, an anti-cracking sticker is laid on the top of the filter oil, and the second surface layer is laid on the top of the anti-cracking sticker.

[0009] Furthermore, in the present invention, the guide unit further includes an insertion rod, which is fixedly connected to the top of the base plate, one end of which extends to the inner cavity of the tilting frame and is threadedly connected to the tilting frame through a nut.

[0010] Furthermore, in the present invention, the guide unit also includes a buffer layer, the base plate is threadedly connected to the road base body through expansion screws, the base plate is located at the bottom of the second surface layer, and the buffer layer is filled on one side of the inclined frame close to the second surface layer and the first surface layer.

[0012] Furthermore, in the present invention, the diversion unit further comprises a water inlet, which is opened on one side of the inclined frame, and the inner cavity of the water inlet is movably connected to a filter plate.

[0013] Beneficial effects: The utility model has the following beneficial effects:

[0014] The utility model improves the use effect of the paved road surface by arranging a pavement unit for paving asphalt pavement on the road base body, and at the same time, the heat insulation layer is arranged between the first surface layer and the second surface layer to provide a thermal insulation effect, reducing the influence of temperature on the pavement unit. By arranging the diversion unit, the two sides of the pavement unit are limited, and the pavement unit is further prevented from being deformed on both sides due to heavy pressure or temperature, and a slope is formed, thereby reducing the cross-sectional height difference between the residential road surface on both sides of the pavement unit.

Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily defined to include all aspects of the present invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the present invention are not limited to any implementation method. In addition, some aspects disclosed in the present invention can be used alone or in any appropriate combination with other aspects disclosed in the present invention.

[0022] Example 1

[0023] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a temperature-insulating asphalt pavement structure, including a road base body 1, a road surface unit 2 is arranged on the top of the road base body 1, and diversion units 3 are arranged on both sides of the road surface unit 2. The road surface unit 2 includes a first surface layer 21, an insulation layer 22 and a second surface layer 23. The insulation layer 22 is laid on the top of the second surface layer 23, and the first surface layer 21 is laid on the top of the insulation layer 22. The diversion unit 3 includes a bottom plate 31, and an inclined frame 33 is provided on the top of the bottom plate 31.

[0024] like Figure 1-4 As shown, the laying of the heat-insulating layer 22 can provide a basic thermal insulation effect between the first surface layer 21 and the second surface layer 23, thereby reducing the impact of temperature on the pavement unit 2. The diversion unit 3 can limit the two sides of the pavement unit 2, form a slope to reduce the cross-sectional height, and divert the flowing rainwater.

[0025] Example 2

[0026] Reference Figure 2-3 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, the pavement unit 2 further includes filter oil 25 , which is sprayed on the top of the road base body 1 . An anti-cracking sticker 24 is laid on the top of the filter oil 25 , and the second surface layer 23 is laid on the top of the anti-cracking sticker 24 .

[0028] The guide unit 3 further includes an insertion rod 32 , which is fixedly connected to the top of the bottom plate 31 . One end of the insertion rod 32 extends to the inner cavity of the tilting frame 33 and is threadedly connected to the tilting frame 33 via a nut.

[0029] The guide unit 3 also includes a buffer layer 38 . The bottom plate 31 is threadedly connected to the road base body 1 through expansion screws. The bottom plate 31 is located at the bottom of the second surface layer 23 . The buffer layer 38 is filled on one side of the inclined frame 33 close to the second surface layer 23 and the first surface layer 21 .

[0030] like Figure 2-3 As shown, the laying of the filter oil 25 and the anti-crack sticker 24 prevents cracks from occurring after the second surface layer 23 is laid. The provision of the insertion rod 32 facilitates the connection and fixation of the tilting frame 33 and the base plate 31. The tilting frame 33 can reduce the gap and provide buffering between the tilting frame 33 and the pavement unit 2 through the buffer layer 38, thereby preventing the pavement unit 2 from being directly squeezed by deformation caused by stress and heat.

[0031] Example 3

[0032] Reference Figure 3-4 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0033] In this embodiment, the guide unit 3 further includes a water outlet 34 . The water outlet 34 is formed on both sides of the inclined frame 33 , and one end of the water outlet 34 is connected to the water guide frame 37 .

[0034] The diversion unit 3 further includes a water inlet 35 . The water inlet 35 is opened on one side of the inclined frame 33 , and a filter plate 36 is movably connected to the inner cavity of the water inlet 35 .

[0035] like Figure 3-4 As shown, the water outlet 34 is opened and connected to the water guide frame 37 to guide the accumulated water in the inner cavity of the inclined frame 33 and make it flow to the external drain port. The opening of the water inlet 35 can facilitate the user to clean the inner cavity of the inclined frame 33. At the same time, the setting of the filter plate 36 is convenient for pedestrians to walk and can also intercept debris, allowing only rainwater to fall into the inner cavity of the inclined frame 33.

[0036] During use, first fix the bottom plate 31 on both sides of the road base body 1 by expansion screws, then spray the filter oil 25 on the road base body 1 and lay the anti-cracking sticker 24 on the filter oil 25 respectively. After completion, cooperate with external paving machines and other equipment to complete the laying of the second surface layer 23, the insulation layer 22 and the first surface layer 21 respectively. After completion, fix the inclined frame 33 and the bottom plate 31 with nuts and plug rods 32, and fill the gap between the inclined frame 33 and the pavement unit 2 with buffer materials. Finally, set the water guide frame 37 to connect with the inclined frame 33, and set the filter plate 36 in the water inlet 35 to complete the paving of the road. When it rains, rainwater flows along the first surface layer 21 to the inclined frame 33 and falls into the inner cavity of the inclined frame 33 through the filter plate 36, and finally flows to the external drain through the water guide frame 37.
