Description

Technical Field

[0001] The present application relates to the technical field of road engineering, and in particular to a road greening facility structure. Background Art

[0002] With the acceleration of urbanization, road construction is increasing. As an important part of urban greening, road greening not only beautifies the urban environment, but also has certain ecological functions. However, in road reconstruction projects, due to the limited area within the red line and dense underground pipelines, the setting of road greening facilities has brought many challenges.

[0003] At present, common road greening facilities include green space, hard pavement, etc. However, in actual application, these facilities often have unreasonable structures. For example, in areas with dense underground pipelines, improper layout of facilities can easily lead to road surface waterlogging, which not only affects the normal use of the road, but also may cause safety hazards to underground pipelines. In addition, existing road greening facilities are also easily damaged during the later maintenance process, increasing maintenance costs.

[0004] In summary, how to design a road greening facility with a reasonable structure to solve the problem of road surface waterlogging and reduce the subsequent maintenance costs has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] In order to solve the problem of road waterlogging and reduce subsequent maintenance costs, the present application provides a road greening facility structure.

[0006] The present application provides a road greening facility structure, which adopts the following technical solution:

[0007] A road greening facility structure comprises green land, hard pavement and retention type grass-planted ditch, wherein the green land and the hard pavement are arranged alternately, and the retention type grass-planted ditch is arranged at the junction of the green land and the hard pavement for collecting and retaining rainwater on the road surface.

[0008] By adopting the above technical solution, green space is used to beautify the urban environment, hard pavement is used to provide convenience for road walking, and rainwater on the road surface is collected and retained by setting up retention grass ditches to solve the problem of road surface waterlogging, improve road safety, and reduce safety hazards to underground pipelines.

[0009] Optionally, a vegetation layer is provided in the green space, and the vegetation layer is made of water-resistant and moisture-resistant plant species.

[0010] By adopting the above technical solution, the water-resistant vegetation layer can absorb and store rainwater, reduce the impact and speed of rainwater runoff, and play a role in retention. This helps to reduce the load on the urban drainage system and prevent rainwater backflow and flooding.

[0011] Optionally, the hard pavement is made of permeable material to improve the water permeability of the ground.

[0012] By adopting the above technical solutions, the use of permeable materials allows rainwater to penetrate directly into the ground, reducing the amount and speed of rainwater runoff. This helps to reduce the load on the urban drainage system and prevent rainwater backflow and flooding.

[0013] Optionally, a filter layer is provided in the retention type grass-planted ditch to filter impurities in rainwater entering the retention type grass-planted ditch.

[0014] By adopting the above technical solution, a filter layer is set up to filter impurities in the water, thereby avoiding damage to the fabric. Plants in the grass-planting ditch need clean water and a suitable environment to grow. The presence of the filter layer can protect the root system and growth environment of the plants.

[0015] Optionally, the filter layer includes a sand and gravel layer and an activated carbon layer, and the sand and gravel layer is arranged above the activated carbon layer.

[0016] By adopting the above technical solution, the gravel layer is mainly used to filter large particles of impurities in rainwater to prevent them from entering the activated carbon layer below. The activated carbon layer is mainly used to adsorb organic matter and some heavy metal ions in rainwater and purify pollutants in rainwater. The combined use of these two filter layers can effectively purify rainwater, improve the water purification effect of retention grass-planted ditches, protect plant growth, extend service life, and improve retention effects.

[0017] Optionally, a drainage outlet is provided at the bottom of the retention grass-planted ditch to discharge the retained rainwater.

[0018] By adopting the above technical solution and setting up a drainage outlet, the accumulated water in the grass-planting ditch can be discharged in time to prevent water stagnation, and avoid water quality problems and health problems such as mosquito and fly breeding caused by stagnant water.

[0019] Optionally, the drain outlet is connected to a drain pipe, which guides the discharged rainwater to the municipal drainage system.

[0020] By adopting the above technical solutions, the municipal drainage system usually has a larger drainage capacity. Guiding the discharged rainwater to the municipal drainage system can improve drainage efficiency, quickly discharge rainwater, reduce water accumulation time, and reduce the risk of water retention.

[0021] Optionally, a guide groove is provided on the hard pavement, and the guide groove is used to guide rainwater on the road surface to flow toward the retention type grass-planted ditch.

[0022] By adopting the above technical solution, the setting of the guide groove can effectively guide rainwater to the retention grass-planted ditch, realize the collection and utilization of rainwater, reduce water retention and accumulation, protect the stability of the road surface, and at the same time reduce the load on the drainage system and improve the permeability of rainwater.

[0023] In summary, the present application includes at least one of the following beneficial technical effects of the road greening facility structure:

[0024] 1. Through the green space, hard pavement and retention-type grass-planting ditch, the road greening facilities can be reasonably arranged, which can not only beautify the urban environment, but also solve the problem of road surface waterlogging, improve the safety of road use, and reduce the safety hazards caused to underground pipelines;

[0025] 2. The vegetation layer in the green space should be made of water-resistant plants that can adapt to the environmental characteristics of road greening facilities, improve the survival rate of plants, and reduce the cost of later maintenance;

[0026] 3. The hard pavement is made of permeable materials, which can improve the water permeability of the ground and further reduce road surface water accumulation;

[0027] 4. A filter layer is set in the retention grass ditch to filter out impurities in the rainwater entering the retention grass ditch, ensuring the cleanliness of the water quality and facilitating the subsequent utilization of the retained rainwater. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] An embodiment of the present application discloses a road greening facility structure.

[0033] Reference Figure 1 and Figure 2 , a road greening facility structure, including green space 1, hard pavement 2 and retention type grass-planting ditch 3. The ingenious combination of these components not only beautifies the urban environment, but also solves the problem of road surface water accumulation, thereby improving the safety of road use and reducing the potential safety hazards caused to underground pipelines.

[0034] Reference Figure 1 and Figure 2 , the green space 1 and the hard pavement 2 are arranged alternately. This layout ensures both the beauty of the road and its functionality. A vegetation layer 11 is arranged in the green space 1, and this layer of vegetation is specially selected from water-resistant plant species. This selection can ensure that the plants can thrive in a humid environment, thereby increasing the survival rate of the plants and reducing the subsequent maintenance costs.

[0035] Reference Figure 1 and Figure 2 The hard pavement 2 is made of a water-permeable material. This material can significantly improve the water permeability of the ground, allowing rainwater to quickly penetrate, thereby further reducing the possibility of water accumulation on the road. Guide grooves 21 are also provided on the hard pavement 2. The function of these guide grooves 21 is to guide rainwater on the road surface to flow to the retention-type grass-planting ditch 3, ensuring that the rainwater can be effectively collected and processed.

This filter layer 31 can filter out impurities in the rainwater entering the retention type grass-planted ditch 3, thereby ensuring the cleanliness of the water quality. The filter layer 31 specifically includes a sand and gravel layer 311 and an activated carbon layer 312, wherein the sand and gravel layer 311 is arranged above the activated carbon layer 312. Such a structure can ensure that when rainwater passes through the filter layer 31, it is first initially filtered by the sand and gravel layer 311, and then deeply treated by the activated carbon layer 312.

[0037] Reference Figure 1 and Figure 2 The bottom of the stagnant grass-planting ditch 3 is provided with a drain 32. The function of this drain 32 is to discharge the stagnant rainwater, thereby preventing the rainwater from accumulating too much in the grass-planting ditch.

[0038] Reference Figure 1 and Figure 2 The drain outlet 32 ​​is also connected to a drain pipe 33. The drain pipe 33 is responsible for guiding the discharged rainwater to the municipal drainage system to ensure that the rainwater can be properly treated while avoiding adverse effects on the urban environment.
