Referring to fig. 1 and 2, the upper end of the supporting layer 4 is flush with the lower end surface of the water permeable brick layer 5, the lower end of the supporting layer 4 is flush with the water guiding inclined plane 21, and the supporting layer 4 includes a supporting skeleton 41 and a stone layer 42 filled in a gap of the supporting skeleton 41. If necessary, in order to ensure that the upper end surface of the crushed stone layer 42 is in close contact with the water permeable brick layer 5 to achieve a good supporting effect, a sand layer can be filled in the upper layer of the crushed stone layer 42 in the process of tamping the crushed stone layer 42, so that the contact area between the crushed stone layer 42 and the water permeable brick layer 5 is remarkably increased.
After the arrangement, when rainwater permeates into the gravel layer 42 through the gaps of the water permeable brick layer 5 and the water permeable brick layer 5, the rainwater can be quickly led to the water guiding inclined plane 21 of the concrete base layer 2 because the gravel layer 42 has extremely large water permeable pores, and the water guiding inclined plane 21 is coated with the waterproof layer 3, so that the rainwater can continuously flow into the water guiding channel 9 at the side of the sidewalk along the water guiding inclined plane 21. The rapid drainage effect of the pavement is realized, and the situation of water accumulation on pavement or brick joints of the pavement can be effectively improved.
In the process, the crushed stone layer 42 can play a certain supporting effect on the water permeable brick layer 5 after being compacted, and the occurrence probability of the phenomenon that the water permeable brick layer 5 is locally settled can be reduced; the supporting framework 41 is compared with the gravel layer 42 and plays a hard supporting role, the water guide inclined plane 21 and the water permeable brick layer 5 are directly connected, and even if pedestrians frequently tread the water permeable brick layer 5 to cause the gravel layer 42 to be further compact and sedimentation, the supporting framework 41 still can play a supporting effect on the water permeable brick layer 5, and the stability of the pavement structure of the application in long-term use is improved.
Specifically, referring to fig. 1 and 2, the supporting framework 41 includes a supporting plate 61 laid on the water guiding inclined plane 21 and a plurality of supporting columns 62 fixedly connected to the supporting plate 61, and the distance between two adjacent supporting columns 62 is not smaller than the width and length dimensions of the single water permeable brick in the water permeable brick layer 5; and a connecting rod 63 is fixedly connected between two adjacent support columns 62, and the connecting rod 63 is flush with the lower end face of the water permeable brick layer 5. The supporting framework 41 is made of engineering plastics, and the supporting plate 61 is hollowed out.

In this embodiment, take square water permeable brick as an example, interval between two adjacent locating holes 72 is half of water permeable brick side length, interval between two side lengths that locating hole 72 is adjacent to it is quarter water permeable brick side length, when a plurality of water permeable bricks splice into water permeable brick layer 5 like this, locating pin 71 on the support column 62 imbeds in locating hole 72, can be with two adjacent water permeable bricks lock each other, make it form a whole to improve water permeable brick layer 5 self stability and stability on supporting layer 4.
In addition, in order to prevent excessive impurities in the rainwater from penetrating into the permeable layer, referring to fig. 1 and 2, a geotechnical cloth layer 8 is disposed between the supporting framework 41 and the waterproof layer 3, so that the geotechnical cloth layer 8 can filter sediment in the rainwater.
Referring to fig. 1 and 2, a plurality of anti-slip bars 64 are fixedly connected to the lower end surface of the support plate 61, a plurality of anti-slip holes 22 corresponding to the anti-slip bars 64 one by one are formed in the upper end surface of the concrete base layer 2, and the anti-slip bars 64 are in plug-in fit with the anti-slip holes 22; the anti-slip holes 22 may be formed at any position of the concrete base layer 2, but in view of reducing damage to the waterproof layer 3, it is preferable to form the protective holes at the highest end of the water guiding inclined surface 21 of the concrete base layer 2.
In this way, after the supporting framework 41 is installed on the water guiding inclined plane 21, the sliding phenomenon of the supporting framework 41 on the water guiding inclined plane 21 can be avoided through the embedded adaptation of the anti-sliding rod 64 and the anti-sliding hole 22, so that on one hand, the stability of the whole pavement structure is improved, and the whole pavement structure is prevented from shifting along the guiding inclined plane; on the other hand, the abrasion of the waterproof layer 3 by the supporting frame 41 can be reduced.
