[0032] Combine the following Figures 1 to 4 , the highway ecological drainage system 100 provided in the embodiment of the present application is described in detail through a specific embodiment.

[0033] Please also read Figures 1 to 4 , Figure 1 It is a structural schematic diagram of the highway ecological drainage system provided by the utility model; Figure 2 It is a partial structural schematic diagram of the highway ecological drainage system provided by the utility model; Figure 3 It is a structural schematic diagram of the landscape planting trough of the highway ecological drainage system provided by the utility model; Figure 4 It is a structural schematic diagram of the interval beam of the highway ecological drainage system provided by the utility model. The highway ecological drainage system 100 provided by one embodiment of the utility model includes a curbstone 10, a seepage storage green belt 20 and a sewage storage and interception mechanism 30. The curbstone 10 is arranged on the side of the highway, and a drainage hole 11 is opened on the curbstone 10; the seepage storage green belt 20 is arranged on one side of the curbstone 10; the sewage storage and interception mechanism 30 is located on one side of the seepage storage green belt 20; wherein, the sewage on the highway can enter the seepage storage green belt 20 through the drainage hole 11 of the curbstone 10, and enter the sewage storage and interception mechanism 30 through the seepage storage green belt 20.

[0034] In this embodiment, the curb 10 is a structure set on the side of the highway, and a drainage hole 11 is opened on it. When rainfall occurs, sewage can enter the seepage green belt 20 below through the drainage hole 11 of the curb 10. The seepage green belt 20 is a strip-shaped greening area located on one side of the curb 10. It is usually composed of plants, soil, stones, etc. When sewage enters the seepage green belt 20, the microorganisms and roots in the plants and soil can play a role in filtering and adsorption, thereby removing pollutants in the water. The roots of plants can absorb harmful substances such as nutrients and heavy metals, and the microorganisms in the soil can degrade organic pollutants. The sewage storage and interception mechanism 30 is located on one side of the seepage green belt 20, and rainwater passing through the seepage green belt 20 can enter the sewage storage and interception mechanism 30, thereby intercepting and filtering impurities (such as gravel particles, etc.) that flow into the sewage storage and interception mechanism 30 together with the rainwater. Through such a setting, the highway ecological drainage system 100 can effectively remove pollutants in rainwater and achieve the purpose of purifying rainwater.

[0035] Among them, the width of the seepage green belt 20 is 1.5m, and the width of the sewage storage and interception mechanism 30 is 1.5m.

[0036] In some embodiments, a plurality of drainage holes 11 are provided, and the plurality of drainage holes 11 are arranged in sequence at intervals on the curb 10. Specifically, the drainage holes 11 are arranged at an interval of 2-5m, and if the water-passing section is circular, the diameter is not less than 10cm; if the water-passing section is rectangular, the side length is not less than 10cm.

[0037] The drainage holes 11 are arranged on the curb 10 at intervals, and the spacing of the drainage holes 11 is 2-5m. If the water-passing cross-section of the drainage hole 11 is circular, the diameter is not less than 10cm; if the water-passing cross-section is rectangular, the side length is not less than 10cm. By arranging the drainage holes 11 on the curb 10 in this way, the discharge and purification process of rainwater can be effectively promoted. The spacing of the drainage holes 11 and the sufficiently large water-passing cross-section size can ensure that rainwater flows smoothly through the drainage holes 11, avoiding water accumulation and blockage, thereby ensuring that rainwater can fully enter the infiltration green belt 20 below for purification.

[0038] In some embodiments, the sewage storage and interception mechanism 30 includes a water-storage plant layer 31, a planting soil layer 32, a fine gravel layer 33, a coarse gravel layer 34 and a water-proof geotextile 35; the water-storage plant layer 31, the planting soil layer 32, the fine gravel layer 33, the coarse gravel layer 34 and the water-proof geotextile 35 are arranged in sequence from top to bottom.

[0039] The water-storage plant layer 31 is mainly used to plant aquatic plants, which can absorb nutrients and pollutants in the water through their roots, thereby purifying the water quality. At the same time, the water-storage plant layer 31 can also inhibit the evaporation of the accumulated water and restore the ecology. The planting soil layer 32 is used to provide a growth environment for aquatic plants, including suitable soil, nutrients and water. The thickness of the planting soil layer 32 can be adjusted as needed to meet the growth needs of the plants. The fine gravel layer 33 can be used to increase the stability and water permeability of the sewage storage mechanism. The fine gravel layer 33 can help water to penetrate quickly and keep the soil moist. The coarse gravel layer 34 is used to provide gaps for storing and temporarily retaining sewage. The coarse gravel layer 34 has a large particle size, which can improve the stability and drainage capacity of the flow channel. The water-proof geotextile 35 is used to separate materials at different levels to prevent impurities and soil from mixing. The water-proof geotextile 35 can play a filtering and protective role, and can also prevent soil siltation and blockage.

[0040] The fine gravel layer 33 is paved with 5-10 mm gravel, and the thickness of the fine gravel layer 33 is 20 cm. The coarse gravel layer 34 is paved with 10-40 mm gravel, the gravel on the upper part of the coarse gravel layer 34 is smaller in size, and the gravel on the lower part is larger in size, and the thickness of the coarse gravel layer 34 is 30 m.

[0041] In some embodiments, the highway ecological drainage system 100 further includes a drainage ditch 40 , which is located on one side of the sewage storage and interception mechanism 30 , and the sewage storage and interception mechanism 30 is connected to the drainage ditch 40 through a drainage pipe 50 .

[0042] The sewage storage and interception mechanism 30 is connected to the drainage ditch 40 through a drainage pipe 50, and the drainage pipe 50 serves to connect the two. The drainage pipe 50 will drain the collected rainwater from the drainage ditch 40 to the sewage storage and interception mechanism 30 for treatment. In this way, the rainwater on the road can be effectively treated and utilized through the drainage system, reducing pollution to the environment.

[0043] In some embodiments, a filter geotextile 51 is provided at one end of the drain pipe 50 close to the sewage storage and interception mechanism 30. The filter geotextile 51 can be used to prevent soil particles from entering the sewage storage and interception mechanism 30 through the drain pipe 50. When the drain pipe 50 discharges water, soil particles may be washed into the pipe together, which may cause the drain pipe 50 to be blocked or the function of the sewage storage and interception mechanism 30 to be affected. The filter geotextile 51 can filter and prevent soil particles from passing through the drain pipe 50 through its fine fiber structure, thereby effectively preventing soil particles from entering the drainage system while allowing water to pass smoothly. The use of the filter geotextile 51 can keep the drainage system in good operation and reduce the maintenance and cleaning work of the drain pipe 50 and the sewage storage and interception mechanism 30.

[0044] In some embodiments, the drainage ditch 40 includes a ditch body 41 , a spacing beam 42 and a landscape planting groove 43 ; the spacing beam 42 is disposed on the ditch body 41 , and the landscape planting groove 43 is disposed on the spacing beam 42 .

[0045] The ditch body 41 is the main structure of the drainage ditch 40, and is used to collect and guide rainwater from the drainage pipe 50. The ditch body 41 can be made of different materials and shapes as needed, such as concrete, plastic, etc., to ensure the strength and durability of the drainage ditch 40.

[0046] The spacing beam 42 is a lateral support structure arranged on the ditch body 41, which can strengthen and stabilize the structure of the ditch body 41. The spacing beam 42 is usually made of reinforced concrete or metal material to ensure that the ditch body 41 can withstand the pressure of road traffic and water flow. The landscape planting trough 43 is a trough-shaped structure arranged on the spacing beam 42, which is used for planting plants and landscaping. The landscape planting trough 43 can enhance the aesthetics of the drainage ditch 40 by planting various plants, such as flowers, shrubs, etc., and play a role in purifying the air and improving the environment. By setting the spacing beam 42 on the ditch body 41 and arranging the landscape planting trough 43 thereon, not only can rainwater be effectively collected and drained, but also green and landscape elements can be added to the road and surrounding environment.

[0047] In some embodiments, planting soil is provided in the landscape planting groove 43, and plants can be placed in the planting soil; and water holes 431 are provided on both sides of the landscape planting groove 43. The water holes 431 can allow excess water to flow out of the planting groove to prevent the soil from being too wet, and prevent the roots of the plants from being soaked in water for a long time, causing root rot and plant death.
