[0002] With the increasing number of abnormal climate, droughts and floods, insufficient urban drainage capacity occurs frequently during peak periods. Cities have the need to increase permeable pavement and build "sponge cities" to eliminate or reduce ground waterlogging and reduce the number of urban waterlogging. As the negative impact of urban ecological damage becomes more and more obvious, as the road area accounts for 8% to 20% of the urban area, it is crucial to further develop road ecology. Realizing road ecology is also an innovative manifestation of low-carbon city development and smart city construction. It is an organic combination of green technology in the new era with social, environmental, humanistic and other factors. The "tidal" phenomenon of urban parking is very obvious, urban parking is becoming more and more difficult, and occupying green space will cause adverse effects such as greening damage. Therefore, it is necessary to build a stable roadside parking lot paving structure that combines "greening" and "parking".

[0003] In the prior art, the anti-rutting ability of general parking lot grass pavement is poor. After a period of use, the greening of the pavement is severely damaged, and the ground will also be bumpy, and the functionality is also damaged. Therefore, it is necessary to improve the stability of the grass pavement. Therefore, a rutting-resistant roadside parking lot grass pavement structure is proposed to solve the above problems.

[0017] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides an anti-rutting roadside parking lot grass paving structure through improvement. The technical solution of the utility model is:

[0019] like Figure 1As shown, it includes a large-size gravel layer 1 arranged on the soil layer, a geotextile 2 is arranged on the upper surface of the large-size gravel layer 1, a composite nutrient planting soil 3 is arranged on the upper surface of the geotextile 2, the geotextile 2 is arranged between the large-size gravel layer 1 and the composite nutrient planting soil 3 to prevent the silt in the composite nutrient planting soil 3 from clogging the gravel gaps and affecting drainage, a high-performance mesh grille 4 is arranged on the upper surface of the composite nutrient planting soil 3, a grass planting layer 5 is arranged around the high-performance mesh grille 4, and the grass planting layer 5 should be laid around the high-performance mesh grille 4 and not cover the high-performance mesh grille 4.

[0020] like Figure 1 and Figure 2 As shown, in one embodiment, the composite nutrient planting soil 3 is composed of small gravel and sand;

[0021] The high-performance mesh grille 4 is in a polygonal mesh shape, and a plurality of rutting piles 6 are arranged on the lower surface of the high-performance mesh grille 4. The rutting piles 6 can be made of concrete or rods or tubes such as UHPC or PE or PPS or PET or PP. The surface of the pile body is roughened to enhance friction. The rutting piles 6 are selected and arranged according to the application scenario load and cost control. The rutting piles 6 extend from the high-performance mesh grille 4 to the bottom soil layer. The specifications of the rutting piles 6 are evenly distributed two to ten per square meter. The high-performance mesh grille 4 is supported by the friction of the rod body and the bottom supporting force to prevent rutting of the grille, and the part can be replaced and maintained. The actual installation method of the rutting piles 6 should be selected according to the engineering situation, and different installation methods should be selected according to the soil texture of the construction land, such as pre-buried or mechanical piling.

[0022] A plurality of drainage pipes 7 are arranged at the bottom of the large-size gravel layer 1, and drainage ditches 8 are arranged on both sides of the high-performance mesh grille 4. The bottom of the drainage ditch 8 is connected to the drainage pipe 7, and the drainage ditch 8 can be covered with large-size gravel to ensure beauty and safety.

[0023] The specific working method is: first, a layer of large-size crushed stone layer 1 is covered on the soil layer. The large-size crushed stone skeleton can provide stable support, and due to the large size of the crushed stone, a stable porosity is retained in the entire crushed stone layer, which can maintain an effective drainage path. Then, a layer of geotextile 2 is laid on the large-size crushed stone layer 1 to prevent the upper mud and sand from leaking and causing blockage in the gaps of the crushed stone, affecting drainage; at the same time, the slope is shaped by compacting the roadbed, and side ditches are arranged around the parking lot to achieve effective drainage. The side ditches are covered with large-size stones to maintain beauty and safety while draining water, and a drainage pipe 7 is buried under the base layer according to the on-site conditions, so that the drainage pipe 7 and the drainage ditch 8 are connected to each other to ensure the drainage effect.
