[0002] Sidewalk refers to the part of the road that is separated by curbs, guardrails and other similar facilities for pedestrians. Sidewalks are very common in cities. Generally, there are sidewalks beside the streets, and the sidewalks are separated by curbs, guardrails or other similar facilities.

[0003] Existing sidewalks are paved with permeable bricks on top to allow natural precipitation to quickly penetrate the surface and replenish groundwater resources in a timely manner. However, due to the limited permeability of permeable bricks, especially in weather with heavy rainfall, the accumulated water on the surface of the permeable bricks is difficult to penetrate in a short period of time, resulting in a large amount of water still accumulating on the ground, affecting pedestrians walking on the sidewalks.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5 A sidewalk structure with a rainwater diversion structure includes a foundation 1, a curb 7 is vertically arranged along the top edge of the foundation 1, and a drainage pipe 8 is penetrated on the curb 7, wherein the curb 7 is formed by multiple curbstones laid adjacent to each other, and the drainage pipe 8 is installed between two adjacent curbstones 7, which can facilitate the setting and installation of the drainage pipe 8. A hole for installing the drainage pipe 8 cannot be opened on the solid surface of the curbstone to prevent the curbstone from being damaged due to stress during drilling, thereby causing a waste of resources.

[0026] like Figure 2 and Figure 4 As shown, a non-permeable bottom layer 2 is provided on the top of the foundation 1, and the top surface of the non-permeable bottom layer 2 is inclined downward toward the curb 7, and a first water collection trough 6 is opened on the side of the top of the non-permeable bottom layer 2 close to the curb 7, and the first water collection trough 6 is correspondingly connected to the drainage pipe 8, and a plurality of diversion grooves 4 connected to the first water collection trough 6 are also provided on the top of the non-permeable bottom layer 2, and a waterproof layer 3 is provided on the top surface of the non-permeable bottom layer 2, wherein the non-permeable bottom layer 2 is paved with gravel, and the waterproof layer 3 is a non-woven fabric, which is laid on the gravel. When rainwater falls on the non-woven fabric, it will be blocked by the non-woven fabric, and with the inclined setting of the non-permeable bottom layer 2 and the diversion groove 4, rainwater that cannot pass through the non-woven fabric can be gathered at the first water collection trough 6 and finally discharged from the drainage pipe 8;

[0027] like Figure 1 and Figure 3 As shown, a permeable layer 9 is arranged above the non-permeable bottom layer 2, and the permeable layer 9 is paved with sand. A barrier layer 15 and a sand and gravel filter 14 for blocking sand and gravel are also arranged between the waterproof layer 3 and the permeable layer 9. The barrier layer 15 is paved with crushed stone, and the sand and gravel filter 14 is laid under the barrier layer 15 and placed on the waterproof layer 3, which is used to block the sand and prevent the sand from falling into the diversion trough 4 and the first water collecting trough 6, and accumulating into clumps under the action of rainwater, thereby blocking the drain pipe 8, the diversion trough 4 or the first water collecting trough 6, and affecting the normal discharge of rainwater.

[0028] like Figure 1 and Figure 5 As shown, a plurality of permeable bricks 10 are installed on the top of the permeable layer 9, and two adjacent permeable bricks 10 are closely attached to each other, and an arc-shaped section 11 is provided along the top edge of the permeable brick 10, so that a water supply channel is formed between the two adjacent permeable bricks 10; a second water collection trough 12 is opened on the side of the permeable layer 9 close to the curb 7, and the bottom of the second water collection trough 12 is connected to the first water collection trough 6 through a plurality of connecting pipes 13, and the side of the second water collection trough 12 corresponds to the channel, so that rainwater on the permeable bricks 10 can flow into the second water collection trough 12 along the channel, and fall into the first water collection trough 6 through the connecting pipe 13, and then be discharged from the drain pipe 8, so as to divert and discharge the rainwater accumulated on the top surface of the sidewalk.

[0029] Furthermore, arc-shaped pipes 5 are installed on the inner side of the guide groove 4, the inner side of the first water collecting groove 6, and the inner side of the second water collecting groove 12. During actual use, the surface of the pipe 5 is a smooth surface, which helps to speed up the flow rate of rainwater on the guide groove 4, the first water collecting groove 6, and the second water collecting groove 12, thereby improving the diversion efficiency of rainwater.

[0030] It should be further explained that in order to prevent foreign debris from falling on the connecting pipe 13 and blocking the connecting pipe 13, so that rainwater in the second water collection tank 12 cannot flow into the first water collection tank 6, thereby affecting the rainwater discharge on the permeable brick 10, a screen is installed on the top of each connecting pipe 13, and the edge of the screen is fixed to the pipe 5 of the second water collection tank 12 by bolts.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
