[0026] According to the present application, the overflow pipe 12 is made of DN300 pipe material.

[0027] According to the present application, the diameter of the reserved hole 15 is 300mm.

[0028] In the related art, the environment-friendly rainwater inlet and the rainwater side ditch (or rainwater pipe inspection well) are connected through a rainwater connecting pipe, which has a large amount of engineering quantity and a large pipe covering height, and in the present application, the bottom plate of the environment-friendly rainwater inlet 10 located in the motor vehicle lane 25 directly utilizes the rainwater side ditch cover plate 13 on the rainwater side ditch 14, which effectively reduces the engineering quantity, saves the investment and reduces the pipe covering height (0.5m≤covering H≤1.0m). In addition, in the present application, the permeable overflow inspection well 7 is arranged in the two-side separation belt 26, and is communicated with the environment-friendly rainwater inlet through the overflow pipe 12, and the permeable overflow inspection well 7 can also drain the rainwater of the pedestrian lane 28 and the non-motor vehicle lane 27 into the environment-friendly rainwater inlet 10, so that the rainwater can be smoothly drained without causing road surface waterlogging or waterlogging disaster when the rainfall is large. The environment-friendly rainwater inlet 10, the rainwater side ditch 14, the permeable overflow inspection well 7 and the overflow pipe 12 in communication together constitute a road drainage system.

[0029] According to the utility model embodiments, the environment-friendly inlet 10 comprises: a cast iron grate 11 fixed on the top of the environment-friendly inlet by a cast iron well ring; a second sewage interception basket 9 connected with the cast iron grate 11; the environment-friendly inlet 10 further comprises a sand-free concrete permeable wall 17 vertically fixed on the bottom of the environment-friendly inlet 10 through a prefabricated block clamping groove 18; the sand-free concrete permeable wall 17 divides the environment-friendly inlet 10 into a first chamber and a second chamber, which are isolated in the lower half and connected in the upper half; the overflow pipe 12 and the reserved hole 15 are both connected with the first chamber; the cast iron grate 11 and the second sewage interception basket 9 are located in the second chamber; and the bottom of the environment-friendly inlet 10 is poured with second-phase concrete 16 of strength grade C15.

[0030] In the related art, the traditional inlet cannot intercept the pollutants such as leaves and sundries brought by road surface cleaning, and the pollutants such as silt, garbage and sundries are prone to cause siltation and blockage of the rainwater pipeline, and the initial rainwater also causes pollution to the downstream water body. The first chamber and the second chamber of the environment-friendly inlet 10 of the utility model embodiments correspond to the inlet cover plate 19 and the cast iron grate 11 at the top, respectively, wherein the cast iron grate 11 is supported on the top of the environment-friendly inlet 10 through the first cross beam 21 and the second cross beam 22. After the rainwater of the motor vehicle lane 25 enters the environment-friendly inlet 10, the rainwater is first preliminarily filtered by the second sewage interception basket 9 to remove larger leaves, garbage and the like, and then further filtered by the sand-free concrete permeable wall 17 at the bottom to remove small-particle-diameter solid substances, thereby contributing to the removal rate of solid suspended particles (SS), and the rainwater in the overflow pipe is directly discharged into the rainwater side ditch together with the rainwater flowing through the environment-friendly inlet, and finally discharged into the downstream river channel.

[0031] According to the utility model embodiments, the sidewalk 28 comprises: a permeable pavement 1 laid on the road surface of the sidewalk 28; a first vertical curb 2 separating the sidewalk 28 and the non-motor vehicle lane 27; the two-side separation belt 26 comprises: a flat curb 3 connecting the two-side separation belt 26 and the non-motor vehicle lane 27; a second vertical curb 4 separating the two-side separation belt 26 and the motor vehicle lane 25; pebbles 5 longitudinally arranged on the inner side of the flat curb 3 and circumferentially arranged on the outer periphery of the permeable overflow inspection well 7; the two-side separation belt 26 adopts a sunken green land 6, the sunken depth of the sunken green land 6 is 0.2 m; and the overflow port of the permeable overflow inspection well 7 is 0.15 m higher than the bottom of the sunken green land 6.

[0032] In the related art, the efficiency of the municipal road drainage system using the sponge measure is not high. In the embodiment of the utility model, the comprehensive sponge measure is combined with the drainage system. The rainwater of the sidewalk 28 generally penetrates into the ground through the water-permeable auxiliary device 1. When the rainfall is large, part of the rainwater that does not penetrate in time enters the non-motor vehicle lane 27 from the first vertical curb stone 2 along the rainwater flow direction 20. Since the non-motor vehicle lane 27 is generally paved with impermeable asphalt pavement, the rainwater continues to flow into the two side strips 26 along the rainwater flow direction 20 and the flat curb stone 3. The two side strips 26 adopt the sunken green land 6, and the pebbles 5 are arranged longitudinally on the side close to the flat curb stone 3. The pebbles 5 are also arranged on the outer periphery of the infiltration overflow inspection well 7, which can dissipate the rainwater energy and preliminarily filter the rainwater. The rainwater is stored, infiltrated and purified in the sunken green land 6. When the rainfall is large, the rainwater in the sunken green land 6 does not have enough time to infiltrate, and after the rainwater is accumulated to a certain height, the rainwater enters the infiltration overflow inspection well 7 through the overflow port higher than the low point of the sunken green land 6, and is finally discharged into the rainwater side ditch 14.

[0033] According to the embodiment of the utility model, the infiltration overflow inspection well 7 comprises a first sewage interception basket 8 located at the top of the infiltration overflow inspection well 7. The infiltration overflow inspection well 7 further comprises a plurality of infiltration holes 23 located at the bottom of the infiltration overflow inspection well 7, and a gravel layer 24 laid below the plurality of infiltration holes 23.

[0034] In the related art, the overflow inspection well located in the two side strips 26 directly delivers the rainwater to the municipal drainage pipeline, increases the drainage pressure of the municipal drainage system, and the garbage wrapped therein is easy to pollute and block the drainage pipeline and the river. In the embodiment of the utility model, the first sewage interception basket 8 is arranged at the top of the infiltration overflow inspection well 7 to preliminarily filter the rainwater, and the infiltration holes 23 and the gravel layer 24 are arranged at the bottom to infiltrate, filter, purify and supplement the groundwater. When the rainfall is large, the rainwater can also flow into the environment-friendly rainwater inlet 10 through the overflow pipe 12.

[0035] The utility model has the following effects:

[0036] (1) The advanced concept of "sponge city" is fully embodied, and the municipal road sponge city construction index (i.e. rainwater annual runoff total control rate and annual runoff pollution control rate) requirements can be fully met;

[0037] (2) The comprehensive measures of infiltration, lag, storage, purification and drainage are adopted to effectively absorb, store, infiltrate, purify and store the municipal road rainwater, effectively reduce the pollution of the initial rainwater to the downstream water body, reduce the urban road waterlogging and urban waterlogging, and better solve the problems of municipal traffic safety, filtration and sewage, ecological environmental protection, difficulty of later operation and maintenance, pipeline covering requirement and other aspects caused by the traditional municipal road drainage mode, and the later repair and maintenance cost is also reduced accordingly;

[0038] (3) effectively beautify the road greening planting, improve the municipal road landscape effect and traffic safety, have higher economic and environmental benefits, promote the healthy and sustainable development of the municipal road sponge city construction.

[0039] The above examples are only examples for clearly illustrating the utility model, and do not limit the implementation mode of the utility model. For those skilled in the art, on the basis of the following description, other different forms of changes or changes can be made, and these belong to the changes, modifications, replacements and deformations derived from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
