In the present embodiment, the road drainage system 10 further includes a water collecting device 13. The water collecting device 13 includes a plurality of water collecting bases 100 arranged in an array. Two adjacent water collection pedestals 100 are spliced to form an integrated array of pedestals. Each water collection base 100 includes a bottom wall 101 and a side wall 102 extending from the edge of the bottom wall 101. The bottom wall 101 and the side wall 102 enclose a water collection sump 103. Wherein, the water collecting base 100 is provided with a water discharging hole 104 communicating the inside and the outside of the water collecting tank 103.

The water permeable device 11 comprises a first water permeable cover 200 and a second water permeable cover 300. The first water permeable cover 200 covers the water collection tank 103 provided on the partial water collection base 100. The second water permeable cover 300 covers the water collecting channel 103 formed on the other part of the water collecting base 100. That is, the first and second permeable covers 200 and 300 cover the water collecting grooves 103 provided on all the water collecting bases 100, and they cover a portion thereof, respectively.

The filter device 12 is arranged in stack with the water permeable device 11. Wherein filter arrangement 12 includes a first filter layer 400 and a second filter layer 500. The first filter layer 400 is arranged on the side of the water permeable device 11 facing away from the water collecting device 13. The second filter layer 500 is arranged on the side of the water permeable means 11 facing the water collecting means 13.

The water collection base 100, the first water permeable cover 200, and the second water permeable cover 300 are all pre-fabricated plastic modules. Through the prefabricated plastic module structure, noise and environmental pollution caused to the surrounding environment when the road drainage system 10 is paved can be reduced, the pavement standardization can be improved, the construction efficiency is improved, and the construction period is greatly shortened.

Wherein, the bottom wall 101 and the side wall 102 of the water collecting base 100 are both rectangular to form a box structure with an opening on the top side. The first and second water- permeable covers 200 and 300 are each rectangular. The first water permeable cover 200 abuts the side wall 102 of the water collection base 100. The second water-permeable cover 300 abuts on the side of the first water-permeable cover 200 away from the water collection base 100. The first and second permeable covers 200 and 300 cover the water collecting grooves 103 formed on the plurality of water collecting bases 100 to form a cover plate of the above-described case structure.

In some application scenarios, water on the road surface such as rainwater, domestic drainage, etc. may flow into the water collecting base 100 below through the first or second water permeable cover 200 or 300. Through the design of the water collecting tank 103 of the water collecting base 100, water permeation can be accelerated, the water discharging capacity of the road water discharging system 10 is improved, and the possibility of water accumulation on the road surface is reduced.

It is understood that the shapes of the bottom wall 101 and the side wall 102 of the water collecting base 100, the first water permeable cover 200 and the second water permeable cover 300 described above are not limited to the present embodiment, but may take any other shapes such as polygonal shapes, flower shapes, circular shapes, irregular shapes, and the like. For example, in some embodiments, the second water-permeable cover 300 may be designed to be pentagonal to enhance the aesthetic appearance of the road surface, and the water collecting base 100 and the first water-permeable cover 200 are correspondingly adjusted to have a shape adapted thereto. The first and second permeable covers 200 and 300 may have a plate shape, or may have other shapes adapted to the water collecting base 100.

Wherein, a plurality of catchment bases 100 are arranged in array, have row direction and column direction. The first and second permeable covers 200 and 300 are alternately arranged in the row direction or the column direction of the plurality of water collecting bases 100.

For example, the first water permeable cover 200 is considered as a, and the second water permeable cover 300 is considered as B. The first and second permeable covers 200 and 300 are alternately arranged along the row direction of the plurality of water collecting bases 100 and are respectively arranged along the column direction of the plurality of water collecting bases 100. The first and second water- permeable covers 200 and 300 are arranged in the row direction of the water collecting bases 100 as the structure of 8230A ABABAB 8230A, and in the column direction as the structure of 8230A AAA 8230A or 8230A BBB 8230A. Each of the first or second permeable covers 200 or 300 covers the water collection tank 103 provided on one of the water collection bases 100.

Similarly, the first and second water- permeable covers 200 and 300 may be alternately arranged along the column direction of the plurality of water collecting bases 100 and may be arranged along the row direction of the plurality of water collecting bases 100. Alternatively, the first and second permeable covers 200 and 300 may be partially alternately arranged along the column direction of the plurality of water collecting bases 100 and respectively arranged along the row direction of the plurality of water collecting bases 100; the other parts are alternately arranged along the row direction of the plurality of water collecting bases 100 and are respectively arranged along the column direction of the plurality of water collecting bases 100.

Of course, in other embodiments, the first and second water- permeable covers 200 and 300 may be arranged in other arrangement structures, such as 8230, aabab \8230, 8230, aaabaaaab \8230, etc., which may be specifically selected according to actual needs and are not specifically limited herein.

In the present embodiment, adjacent two sidewalls 102 of adjacent water collecting bases 100 are connected to each other. For example, one water collecting base 100 has a rectangular bottom wall 101 and four side walls 102 extending from four side edges of the rectangular bottom wall 101, and the four side walls 102 are respectively attached to the adjacent side walls 102 of the water collecting bases 100 on the four sides of the water collecting base 100, so that the water collecting bases 100 are spliced to form the base array.

The ends of the first water-permeable cover 200 abut against two adjacent side walls 102 of two adjacent water collecting bases 100. For example, one first water permeable cover 200 has left and right ends, the left end of which abuts against the left wall of one water collecting base 100 and the right wall of the other water collecting base 100 on the left side of the water collecting base 100, and the right end of which abuts against the right wall of the water collecting base 100 and the left wall of the other water collecting base 100 on the right side of the water collecting base 100. By this connection, the first water-permeable cover 200 can stably cover the water collecting channel 103 of the water collecting base 100, and at the same time, the connection stability between the water collecting base 100 and two adjacent water collecting bases 100 can be improved.

One end of the second water-permeable cover 300 abuts against one of the adjacent two first water-permeable covers 200, and the other end abuts against the other of the adjacent two first water-permeable covers 200. That is, the left end of the second water-permeable cover 300 abuts on the first water-permeable cover 200 on the left side thereof, and the right end thereof abuts on the other first water-permeable cover 200 on the right side thereof. Compare in the structure that only has the lid that permeates water of a plurality of same aspect, the structure that two kinds of lid stacks of permeating water that this application provided is favorable to promoting the connection stability between a plurality of lids of permeating water.

It should be noted that in the embodiment of the present application, the connection between the water collecting bases 100, the connection between the water collecting base 100 and the first water permeable cover 200, and the connection between the first water permeable cover 200 and the second water permeable cover 300 may be formed by one or more detachable connection manners, such as clamping, riveting, pin-jointing, screw-jointing, bonding, magnetic-attracting connection, etc.

Through the above design, the road drainage system 10 may be respectively provided with the adaptive fixed connection structures on the opposite sides of the side wall 102 of the water collecting base 100 and the first water permeable cover 200, and additionally respectively provided with the adaptive fixed connection structures on the opposite sides of the first water permeable cover 200 and the second water permeable cover 300, so that the water collecting base 100, the first water permeable cover 200 and the second water permeable cover 300 may be fixed to each other layer by layer to improve the stability of the road drainage system 10. Of course, the water collecting base 100, the first water permeable cover 200 and the second water permeable cover 300 which are stacked may be reinforced and connected by fasteners such as screws, rivets, and buckles to achieve a reinforcing effect.

In addition, the stacked arrangement of the first and second permeable covers 200 and 300 is also beneficial to prevent rainwater from penetrating through gaps between adjacent permeable covers, thereby reducing the possibility of water penetrating into the foundation under the road drainage system 10 and further improving the stability of the road drainage system 10.

In other embodiments, each first water-permeable cover 200 may abut on only one sidewall 102 of the water collecting base 100; alternatively, each first water-permeable cover 200 may abut on the side walls 102 of at least three water collecting bases 100.

It will be appreciated that in the construction of urban roads, the foundations, base course and cover course as a whole should be considered systematically. The present application provides a road drainage system 10 that first compacts the foundation before installing the water collection base 100, ensuring that the degree of compaction reaches 87% or more. And then the water collecting base 100, the first water permeable cover 200 and the second water permeable cover 300 are laminated to ensure that the road drainage system 10 has high overall stability.

In addition, filter materials forming the first filter layer 400 and the second filter layer 500 are disposed on each plastic module of the road drainage system 10 to filter water flowing into the road drainage system 10.

In this embodiment, the first filter layer 400, i.e. the filter layer described above, is used as the first filter structure of the road drainage system 10, and includes a paving filter 401. The paving filter material 401 is paved on one side of the first water-permeable cover 200 departing from the water collecting base 100 and connected between two adjacent second water-permeable covers 300.

Optionally, the side of the first filter layer 400 facing away from the first water permeable cover 200 is flush with the side of the second water permeable cover 300 facing away from the water collection base 100. The second water-permeable cover 300 and the first filter layer 400 may together constitute a face layer of the road drainage system 10.

Two adjacent second water-permeable covers 300 are respectively abutted against two ends of one first water-permeable cover 200, so that a groove with the first water-permeable cover 200 as a bottom wall and the second water-permeable cover 300 as a side wall is formed, and the first filter layer 400 is laid on the bottom wall of the groove and connected to the side wall of the groove.

In this way, the first filter layer 400 is embedded in the water permeable device 11, and the binding force between the first water permeable cover 200 and the second water permeable cover 300 is increased, so that the possibility of falling off of the second water permeable cover 300 is reduced, and the stability of the whole structure of the road drainage system 10 is improved.

The paving filter material 401 constituting the first filter layer 400 may be pervious concrete, and the pervious concrete is poured into the groove formed by the first pervious cover 200 and the second pervious cover 300 to bond the adjacent second pervious cover 300 together, so that the surface layer of the road drainage system 10 is smoother, more stable and less prone to loosening, and the possibility of road surface depression caused by loosening of the second pervious cover 300 can be reduced.

Alternatively, the pervious concrete may be used in different proportions depending on the strength requirements. The pervious concrete in the embodiment adopts 42.5 cement, a water reducing agent, water and stones. Wherein the 42.5 cement is the cement with the strength of 42.5 MP.

The proportion of the C20 pervious concrete is 42.5 cement: water reducing agent: water: stone =139:2:50:650.

the proportion of the C25 pervious concrete is 42.5 cement: water reducing agent: water: pebble =150:3:53:650.

the proportion of the C30 pervious concrete is 42.5 cement: water reducing agent: water: pebble =160:4:56:650.

optionally, the paving filter 401 may also be filter materials with filtering effects such as water permeable bricks, cobblestones, ceramic granules, gravel and the like. Taking the permeable bricks as an example, a plurality of permeable bricks may be laid on a side of the first permeable cover 200 facing away from the water collecting base 100 to form a first filter layer 400, and the first filter layer 400 abuts against the adjacent second permeable cover 300.

It is understood that in other embodiments, the first and second water- permeable covers 200 and 300 may be arranged in other arrangements, in which case the water-permeable device 11 has at least two second water-permeable covers 300, and the paving filter 401 is connected between the adjacent second water-permeable covers 300.

In some embodiments, the first filter layer 400 may also be laid on the side of the second water permeable cover 300 facing away from the water collection base 100, i.e. the first filter layer 400 is laid over the water permeable means 11 to form a surface layer of the road drainage system 10.

In this embodiment, the second filter layer 500 is disposed on the side of the second water permeable cover 300 facing the water collection base 100. Specifically, second filter layer 500 includes a screen 501, and filter particles 502 disposed within screen 501. The screen 501 has a plurality of meshes for water permeation. Filter particles 502 have a particle size larger than the mesh diameter of screen 501 so that filter particles 502 may fit within screen 501 to form second filter layer 500.

Wherein, the filter screen 501 is hung on the water collecting device 13 and/or the water permeable device 11, and at least a part of the filter screen 501 is located on one side of the second water permeable cover 300 facing the water collecting base 100.

Alternatively, the hanging members 503 are respectively installed on opposite sides of the adjacent first water-permeable covers 200. The filter net 501 is hung on the hanging member 503, so that the filter net 501 and the filter particles 502 therein form the second filter layer 500 for filtering the water flow passing through the second water permeable cover 300. Wherein, the filter screen 501 is a soft net bag. In other embodiments, the screen 501 may be a rigid structure, such as a trough with a mesh opening in the bottom wall.

Optionally, the water collecting base 100 and the second water permeable cover 300 may also be provided with a hanging member 503.

For example, a hanging member 503 may be installed on the inner side of the side wall 102 of the water collecting base 100 against which the first water permeable cover 200 abuts, so that the second filter layer 500 may be formed on the side of the first water permeable cover 200 facing the water collecting base 100 or the side of the second water permeable cover 300 facing the water collecting base 100 by hanging the filter mesh 501 on the hanging member 503.

For another example, a hanging member 503 may be installed on a side of the second water-permeable cover 300 facing the water collecting base 100, i.e., on a bottom side thereof, so that the second filter 500 may be formed on the side of the second water-permeable cover 300 facing the water collecting base 100 by hanging the filter mesh 501 on the hanging member 503.

The hanging member 503 includes, but is not limited to, a hook, a buckle, and other members that can be used to hang the filter screen 501. The filter particles 502 include, but are not limited to, any filter material that can be installed on the filter screen 501 and can achieve a filtering effect, such as ceramic particles, gravel, pebbles, etc.

Alternatively, the strainer 501 may be directly hung on the water collecting base 100, the first water permeable cover 200 and/or the second water permeable cover 300.

Through the above design, in the embodiment of the present application, the second filtering layer 500 is disposed on one side of the water permeable device 11 facing the water collecting device 13, and the second filtering layer is installed in the space of the water collecting tank 103, so that the filtering capability of the road drainage system 10 is improved.

In this embodiment, the filter particles 502 are ceramic particles. The ceramsite can be obtained by mixing riverway bottom mud, clay, fly ash and water with the total weight being 2% -8% of the total weight of the mixture, putting the mixture into a granulator to form raw material balls, roasting the raw material balls, taking out the roasted raw material balls and cooling the roasted raw material balls.

The pervious concrete and the ceramsite have a great effect of removing pollutants in a water body. By combining the ceramsite and the pervious concrete, the removal of SS in runoff pollutants is facilitated, and the huge specific surface area of the ceramsite and the pervious concrete is beneficial to adsorbing pollutants such as micro-plastics, COD (chemical oxygen demand), ammonia nitrogen and the like of the runoff pollutants on the ground. In addition, after the filter material is adsorbed for a period of time, the water permeable cover and the ceramsite can be taken out, soaked in clear water and analyzed to achieve the regeneration effect, so that the problem of poor water permeability caused by blockage of the filter layer due to long-term use is solved.

In the present embodiment, the first and second water- permeable covers 200 and 300 are alternately arranged in the row direction of the plurality of water collecting bases 100 and are arranged in the column direction thereof, respectively.

Wherein, the water collecting base 100, the first water permeable cover 200 and the second water permeable cover 300 have the matched tenon-and-mortise structure. Each of the first water permeable covers 200 is respectively snapped on one of the water collecting bases 100 in the column direction. Each of the second water permeable covers 300 is respectively snapped on one of the first water permeable covers 200 in the column direction. The plurality of first and second water- permeable covers 200 and 300 are snap-fitted in a stacked manner in the row direction.

The first filter layer 400 is laid on a side of all the first water permeable covers 200 facing away from the water collection base 100 to improve the stability of connection between the plurality of first water permeable covers 200 and the plurality of second water permeable covers 300 arranged in the column direction.

Fig. 5 is a schematic sectional view of the first water-permeable cover in the embodiment of fig. 1.

Optionally, the tenon 110 and the mortise 120 are respectively arranged on one of the two adjacent side walls 102 of the two adjacent water collecting bases 100. Two adjacent water collecting pedestals 100 are connected by tenons 110 and mortises 120.

Specifically, the outer sides of the two opposite side walls 102 of each water collecting base 100 are respectively provided with a tenon 110 and a mortise 120. In other words, the water collecting base 100 has a front side wall, a rear side wall, a left side wall and a right side wall. The front side wall and the rear side wall are arranged oppositely, and the left side wall and the right side wall are arranged oppositely. The front and left side walls of each water collecting base 100 are provided with tenons 110, and the rear and right side walls thereof are provided with mortises 120.
