Further, the water-permeable belt further comprises a geotextile layer, and the geotextile layer is arranged between the filter layer and the planting soil layer.

Through adopting above-mentioned technical scheme, the geotechnological cloth layer separates filter layer and planting soil layer, and its mesh size is far less than the width in the inside gap of filter layer, can avoid planting the intraformational soil diffusion of soil to the filter layer in betterly, and then avoids the sieve mesh on the infiltration pipe to be blockked up.

Furthermore, the water permeable belt further comprises pebble belts, the pebble belts are laid on the filter layer in pairs, and the pebble belts are arranged close to the sidewalk.

By adopting the technical scheme, when rainwater flows into the water permeable belt from the sidewalk, a certain drop is formed, the impact on the water permeable belt is large, and the rainwater easily penetrates through the aquatic plant layer to disperse the structure of the filter layer, so that the pebble belt is laid above the filter layer, and pebbles with large volume can effectively resist the impact of water flow; after the pebble belt is laid, a cool environment is formed below the pebbles, so that aquatic animals such as shrimps, crabs and fishes can conveniently inhabit, the biological diversity of the water permeable belt can be greatly increased, and the ecological balance is more stable.

Furthermore, the filter layer is formed by laying scattered ceramic grains.

By adopting the technical scheme, the ceramsite shell is hard, has strong resistance to water flow scouring erosion, has better corrosion resistance and has long service life; in addition, the ceramsite has excellent heat insulation performance, is covered above a planting soil layer, can well protect the roots of aquatic plants, and can prevent the aquatic plants from being frostbitten in a low-temperature environment.

Furthermore, a road tooth is arranged on one side of the sidewalk facing the permeable belt, and a water outlet is formed in the road tooth.

By adopting the technical scheme, the road teeth are arranged, so that the pedestrians are prevented from stepping on the water permeable belt when walking on the sidewalk.

Furthermore, the bottom surface of the water outlet is obliquely arranged, and the height of the water outlet facing one end of the water permeable belt is lower than that of the other end of the water outlet.

Through adopting above-mentioned technical scheme, the outlet bottom surface slope, when the rainwater flows in this department, highly constantly reduces, and gravitational potential energy turns into kinetic energy, and the velocity of flow accelerates to accelerate the drainage rate in outlet, make the difficult ponding in road surface.

Furthermore, a step plate is arranged on the road teeth.

By adopting the technical scheme, the step plates are erected on the road teeth on the two sides of the water permeable belt for pedestrians to step on, so that the pedestrians can conveniently stride over the water permeable belt.

To sum up, the utility model discloses following beneficial effect has:

1. the drainage function and the attractiveness are achieved, the pavement is not required to be dug when the permeation tube is replaced, and the damage and repair to the pavement are avoided, so that the engineering quantity can be reduced, and the cost is saved;

The water outlet 12 is a through hole, one end of the bottom surface of the water outlet is connected with the sidewalk 1 and is flush with the sidewalk 1, and the other end of the water outlet is inclined downwards to guide rainwater on the sidewalk 1 into the water permeable belt 2.

As shown in figure 1, a plurality of step boards 13 are erected on the road teeth 11 at two sides of the water permeable belt 2, the step boards 13 are arranged along the horizontal direction and cross over the water permeable belt 2, and two ends of the step boards are placed on the road teeth 11 and are uniformly distributed along the length direction of the water permeable belt 2.

As shown in FIG. 1, the filtering layer 22 is formed by laying scattered ceramsite, and the particle size of the ceramsite is between 5mm and 10 mm. Two pebble belts 27 are laid on the filter layer 22, and the two pebble belts 27 are arranged along the length direction of the water permeable belt 2, are respectively positioned at two sides of the water permeable belt 2 and are arranged close to the sidewalk 1.

The particle size of the pebbles is 50mm to 200mm, and when rainwater flows into the water permeable belt 2 through the water outlet 12, the rainwater is firstly intercepted by the aquatic plant layer 21 and then impacts on the pebble belt 27, so that the ceramsite of the filter layer 22 cannot be dispersed.

As shown in FIGS. 1 and 2, the thickness of the filter layer 22 is 200mm, the permeation tube 24 is embedded in the middle upper part of the filter layer 22, the upper surface thereof is provided with a sieve 241, and the aperture of the sieve 241 is less than 5 mm. The permeation tube 24 is reversely buckled with a baffle plate 25, the baffle plate 25 is parallel to the permeation tube 24, the cross section of the baffle plate 25 is U-shaped, the opening of the baffle plate is downward, the baffle plate and the permeation tube 24 are embedded in the filter layer 22, and two side walls of the baffle plate 25 extend downwards to the bottom of the filter layer 22.

After entering the water permeable belt 2, the rainwater firstly passes through the aquatic plant layer 21, then seeps down to the bottom of the filter layer 22, bypasses the baffle plate 25, then upwards seeps to the top of the permeation pipe 24, enters the permeation pipe 24 through the sieve holes 241, and then is discharged through the permeation pipe 24. In the process, the rainwater is fully filtered, impurities with larger volume are filtered out, and the sieve holes 241 and the permeation tube 24 cannot be blocked.

As shown in fig. 1, the geotextile layer 26 separates the filter layer 22 from the planting soil layer 23, and prevents the soil in the planting soil layer 23 from diffusing upwards into the rainwater, thereby preventing water and soil loss.
