Description

Technical Field

[0001] The invention relates to the technical field of pavement structure, in particular to a permeable pavement and a cleaning method thereof. Background Art

[0002] Permeable pavement is water-permeable and can quickly eliminate water on the road when it rains, making the road quickly available for use. Colored permeable pavement is commonly seen in parks or sports fields. It is not only beautiful, but also has good water permeability, which prevents water from accumulating on the road during rainy days and affecting pedestrians' walks. Rainwater flowing into the ground can also effectively replenish groundwater.

[0003] Because there are many green belts on the roadside, leaves in the green belts will fall onto the road surface. When it rains, leaves or debris on the road surface will flow with the water toward the manhole cover on the road. When the dirt accumulates to a certain level, it will block the manhole cover, causing water accumulation on the road. Summary of the invention

[0068] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0069] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0070] like Figure 1 , Figure 2 , Figure 4 As shown, an embodiment of the present invention provides a permeable pavement, comprising: a soil base layer 1, a fixing bar 2, a permeable layer 3, a drainage component 4 and a pavement layer 5. The fixing bar 2 is connected to the soil base layer 1 through an anchor rod and is arranged on both sides along the length direction of the soil base layer 1, and a filling area 21 is formed between the two fixing bars 2. The permeable layer 3 is arranged in the filling area 21 and is connected to the fixing bar 2. The drainage component 4 is arranged on both sides of the top of the soil base layer 1 and is located on the inner side of the fixing bar 2. The pavement layer 5 is laid on the top of the permeable layer 3, and a permeable gap 6 is provided between the pavement layer 5 and the fixing bar 2.

[0071] During precipitation, rainwater penetrates into the permeable layer 3 through the pavement layer 5, then enters the drainage assembly 4 through the permeable layer 3, and is discharged to the underground pipe network for treatment. In order to improve the bearing capacity of the pavement, the permeable layer 3 includes: a reinforcing plate 31 and a gravel layer 32. A plurality of filling holes are provided on the top of the reinforcing plate 31, and both ends of the reinforcing plate 31 are connected to the fixing bar 2. The gravel layer 32 is filled into the filling hole. The reinforcing plate 31 is made of a steel plate 33, and a slot 34 matching the thickness of the steel plate 33 in the other direction is cut on the steel plate 33 in the transverse or longitudinal direction. The filling hole is formed in the middle of the transverse steel plate 33 and the longitudinal steel plate 33. The gravel layer 32 is mainly formed by mixing small gravel and coarse sand and filling it into the filling hole of the reinforcing plate 31.

[0072] When it rains, rainwater flows into the gutter 41 along the permeable gaps 6 on both sides of the road. When part of the permeable gaps 6 are blocked by dirt, the rainwater can flow along the blocked part to the next section and then enter the gutter 41. During the rain, part of the dirt is washed away by the rainwater, thereby improving the permeability of the permeable gaps 6.

[0073] It should be noted that, after the pavement layer 5 is paved, the height of the pavement is lower than the height of the fixing strip 2 after installation.

[0074] During the laying process, the water inlet connected to the urban sewage network is set at the permeable gap 6 between the fixed strip 2 and the road surface, so that the water inlet is in the shape of a long strip. When one section is blocked, the water flow can flow to the rear along the direction of the road, and then enter the drainage component 4 in an unblocked place, thereby improving the water permeability efficiency during rainfall.

[0075] In one embodiment, if Figure 1 and Figure 3 As shown, in order to facilitate the end-to-end connection of the two fixing bars 2, a dovetail tenon 22 is provided at one end of the fixing bar 2, and a dovetail groove 23 is provided at the other end, and the dovetail tenon 22 and dovetail groove 23 on the two adjacent fixing bars 2 match.

[0076] In another embodiment, a limiting block is provided on the dovetail tenon 22 , and a limiting groove is provided in the corresponding dovetail groove 23 , so that two adjacent fixing bars 2 are fixed more firmly.

[0077] In one embodiment, if Figure 1 , Figure 4 As shown, the drainage assembly 4 includes: a drainage ditch 41, an isolation net 42, an interception net 43 and a flow sensor 44. The drainage ditch 41 is arranged on the soil base 1 and is located on one side of the fixing bar 2. The isolation net 42 is installed on the top of the drainage ditch 41. The interception net 43 is arranged in the permeable gap 6. The flow sensor 44 is installed in the drainage ditch 41.

[0078] During the precipitation process, the isolation net 42 and the interception net 43 filter the dirt in the rainwater to prevent the dirt from entering the drainage ditch 41 and clogging the drainage ditch 41. When the flow sensor 44 set in the drainage ditch 41 detects that the flow in the ditch is significantly different from the flow value of the precipitation on that day, the information is fed back. Then the staff needs to check each interception net 43 along the road.

[0079] In one embodiment, if Figure 1 and Figure 4 As shown, in order to facilitate automatic cleaning of dirt on the isolation net 42 and the interception net 43, the drainage component 4 further includes: a backwash component 7, and the backwash component 7 is installed in the drainage ditch 41.

[0080] More specifically, the backwash assembly 7 includes: a flushing pipe 71, a flushing pump 72, a diverter pipe 73 and a flushing nozzle 74. One end of the flushing pipe 71 is connected to the regenerated water storage well. The flushing pump 72 is installed on the flushing pipe 71. The diverter pipe 73 is connected to the flushing pipe 71 through a multi-way pipe, and the diverter pipe 73 is installed on the inner side of the isolation net 42 and the interception net 43. A plurality of flushing nozzles 74 are sequentially arranged along the axial direction of the diverter pipe 73, and the spray holes of the flushing nozzles 74 are arranged obliquely toward the isolation net 42 and the interception net 43.

[0081] When flushing is required, the flushing pump 72 is started to send the regenerated water into the flushing pipe 71, and then the regenerated water is introduced into each branch pipe 73 through the multi-way pipe. Then, the flushing nozzle 74 arranged on the branch pipe 73 is sprayed out to flush the isolation net 42 and the interception net 43.

[0082] In one embodiment, if Figure 1 As shown, in order to facilitate the laying of the pavement layer 5, a leveling layer 8 and a cushion layer 9 are sequentially arranged between the pavement layer 5 and the permeable layer 3. The leveling layer 8 has a thickness of at least 30 mm and is paved with coarse sand. The cushion layer 9 has a paving thickness of 280-220 mm, and is made of crushed stone with a particle size of 5-60 mm, and is compacted, with a compaction coefficient of at least 93%.

[0083] In one embodiment, if Figure 6 and Figure 7 As shown, a plurality of partition plates 110 are provided at intervals in the drainage ditch, and a driving mechanism 120 is provided corresponding to each partition plate 110 .

[0084] When it is necessary to backwash the dirt in the permeable pavement, the drainage ditch 41 is blocked by the partition plate 110 set in the drainage ditch. After the blockage, the flushing nozzle 74 in the corresponding area is controlled to flush the isolation net 42 and the interception net 43. At this time, the flushing water flow will be concentrated in the corresponding drainage ditch 41. When the water accumulates to a certain amount, it will overflow along the isolation net 42 and the interception net 43, so that part of the dirt is washed onto the road surface layer 5, which is convenient for municipal sanitation workers to clean.

[0085] When the road section is cleaned, the partition plate 110 is controlled to be opened to facilitate the water flow to the next area, and then the opened partition plate 110 is controlled to be closed, so that the next area forms a relatively closed area, reducing water consumption.

[0086] It should be noted that when the partition plate 110 is not in use, it is completely embedded in the side wall of the drainage ditch 41 under the drive of the driving mechanism 120. The driving mechanism 120 is an electric push rod or a linear motor.

[0087] In another embodiment, Figure 8 As shown, the partition plate 110 is provided with a clearance groove 130 matching the interception net 43, so as to facilitate the backwashing water to seep through the isolation net 42 and flush out the dirt in the sewage during the seepage process.

[0088] In one embodiment, if Figure 5 As shown, in order to improve the water permeability of the road surface, the road surface layer 5 is paved with a plurality of permeable bricks, and the gap between two adjacent permeable bricks is filled with permeable sand 10.

[0089] A method for cleaning a permeable pavement as described above comprises:

[0090] S01, when precipitation occurs, the flow rate monitoring sensor in the drainage component 4 detects the rainwater flow in the drainage ditch 41;

[0091] S02, after the precipitation stops, use manual cleaning or backwashing assembly 7;

[0092] S03, when the backwashing assembly 7 is used for cleaning, the flushing pump 72 is started, and the flushing pressure of the flushing nozzle 74 on the diversion pipe 73 is adjusted according to the rainwater flow in the drainage ditch 41;

[0093] S04. The flushing nozzle 74 on the diversion pipe 73 is aimed at the isolation net 42 and the interception net 43 to flush and backwash out the dirt blocking the gap.

[0094] When precipitation occurs, some dirt will flow toward the side of the permeable gap 6 with the rainwater, and enter the drainage ditch 41. Some dirt will adhere to the isolation net 42 and the interception net 43. When the dirt accumulates to a certain extent, the isolation net 42 and the interception net 43 will be blocked, causing water to accumulate on the road surface. When the flow sensor 44 set in the drainage ditch 41 detects that the amount of water entering the drainage ditch 41 is not proportional to the precipitation outside, it indicates that the isolation net 42 or the interception net 43 is blocked. After the precipitation is completed, the flushing pump 72 transports the water in the regenerated water storage well to the flushing pipe 71, and the regenerated water is transported to each branch pipe 73 through the multi-way pipe. The regenerated water enters the branch pipe 73, and then the isolation net 42 and the interception net 43 are flushed through the flushing nozzle 74 installed on the branch pipe 73. During the flushing process, the flushing nozzle 74 can adjust its spraying pressure according to the amount of dirt on the isolation net 42 and the interception net 43, so as to better clean the dirt.

[0095] During the flushing process, part of the dirt on the isolation net 42 and the interception net 43 will be flushed into the drainage ditch 41, and part of it will be flushed onto the road surface and cleaned by the municipal sanitation department.

[0096] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
