Description

Technical Field

[0001] This invention relates to the technical field of road drainage, and in particular to a drainage road surface. Background Technology

[0002] Rainy or heavy rain weather can easily cause water accumulation on roads. To ensure that excess water can be drained in a timely manner, a well-drained pavement is needed to reduce traffic inconvenience caused by road flooding. A well-drained pavement consists of the pavement itself and drainage ditches located on both sides of the pavement. The upper end of the drainage ditch is flush with the pavement by a drainage cover, and the bottom of the drainage ditch is equipped with drainage pipes to remove water from the road surface.

[0003] Traditional municipal drainage systems require drainage structures to reduce water accumulation and rainwater damage to the road surface. Road drainage mainly relies on drainage ditches set up on both sides of the road. To ensure the safety of people and vehicles, drainage ditches are usually covered with covers with drainage holes.

[0004] Regarding the aforementioned technologies, traditional municipal drainage facilities are connected to the municipal drainage network or underground drainage ditches. As a result, the waste gas generated by the sewage from the drainage network and underground drainage ditches will overflow from the drainage outlet of the drainage ditch. On the one hand, the waste gas will pollute the environment, and on the other hand, the toxic waste gas will harm the human body. Summary of the Invention

[0005] In order to improve the problem of waste gas generated by sewage from drainage pipe networks and underground drainage ditches overflowing from the drainage outlets of drainage ditches, this application provides a drainage pavement.

[0006] This application provides a drainage pavement, which adopts the following technical solution:

[0007] A drainage pavement includes a drainage ditch, a ditch cover plate at the top of the drainage ditch, and a long strip water collection tank at the bottom of the drainage ditch. The long strip water collection tank is connected to the municipal drainage network. A drainage slot is provided at the junction of the long strip water collection tank and the drainage ditch. An odor-proof component is provided at the bottom of the drainage ditch. The odor-proof component includes an arc-shaped strip plate located at the bottom of the drainage ditch through the drainage slot and an arc-shaped slot located at the bottom of the drainage ditch. The outer arc surface of the arc-shaped strip plate and the inner arc surface of the arc-shaped slot are fitted together. The arc-shaped slot is connected to the drainage slot.

[0008] By adopting the above technical solution, during rainy or rainy weather, rainwater from the road surface flows to the drainage ditches on both sides of the road surface. After the drainage is completed, the arc-shaped strip rises vertically through the tension spring until the outer arc surface of the arc-shaped strip fits into the inner arc surface of the arc-shaped groove. This achieves the separation between the drainage ditch and the long water collection tank, minimizing the emission of unpleasant gases from the long water collection tank.

[0009] Optionally, the drainage ditch is provided with a reset component for resetting the arc-shaped strip. The reset component includes several reset cylinders fixedly installed at the bottom of the drainage ditch, a reset rod passing through the reset cylinder, a reset panel fixedly installed around the reset rod, and a tension spring fixedly connected between the reset panel and the inner top surface of the reset cylinder. The bottom end of the reset rod passes through the reset cylinder and is fixedly installed on the outer arc surface of the arc-shaped strip.

[0010] By adopting the above technical solution, after the discharge is completed, the arc-shaped strip rises vertically by the tension spring until the outer arc surface of the arc-shaped strip fits into the inner arc surface of the arc-shaped groove, thereby achieving the effect of separating the drainage ditch and the long water collection tank.

[0011] Optionally, the drainage ditch is provided with a rainwater filtration component, which includes several waste troughs in the drainage ditch and filter screens on the sidewalls of two adjacent waste troughs; the waste troughs and the filter screens are composed of filter wire mesh.

[0012] By adopting the above technical solution, rainwater flows to the bottom of the drainage ditch after being filtered by the filter screen, while the garbage and impurities intercepted by the filter screen and waste trough are directly stored on the top of the filter screen and waste trough.

[0013] Optionally, the filter screen is inclined along a direction away from the center of the drainage ditch.

[0014] By adopting the above technical solution, rainwater flows from the highest point of the filter screen to the lowest point of the filter screen, thereby increasing the contact area between the rainwater and the filter screen and thus improving the filtration efficiency of the filter screen.

[0015] Optionally, the ditch cover is provided with a rainwater collection channel group, which includes a plurality of flow guiding grooves opened on the top of the ditch cover; the inner bottom surface of the flow guiding groove is inclined towards the center of the drainage ditch, and the position of the inner bottom surface of the flow guiding groove near the center of the drainage ditch is connected to the drainage ditch.

[0016] By adopting the above technical solution, rainwater from the road surface flows to the drainage ditches on the left and right sides of the road surface, and the rainwater is collected in the middle of the drainage ditch through the guide groove of the ditch cover.

[0017] Optionally, the drainage ditch is provided with a garbage collection component, which includes a plurality of garbage collection cylinders installed in the drainage ditch; the plurality of garbage collection cylinders pass through a plurality of waste trough plates respectively.

[0018] By adopting the above technical solution, the garbage inside the waste trough can smoothly slide into the inside of the garbage collection bin, thereby realizing the collection of garbage in rainwater.

[0019] Optionally, the garbage collection bin is equipped with a rainwater infiltration component, which includes a filter screen cylinder installed inside the garbage collection bin; the bottom of the garbage collection bin is connected to the drainage ditch, and the filter screen cylinder is composed of filter wire mesh.

[0020] By adopting the above technical solution, the rainwater remaining in the garbage collection bin flows into the bottom of the garbage collection bin through the filter screen body, and the rainwater at the bottom of the garbage collection bin flows back to the drainage ditch through the water filtration holes. At this time, the garbage and impurities are intercepted on the inside of the filter screen body.

[0021] Optionally, the drainage ditch is equipped with a cleaning component for cleaning the filter screen and waste trough. The cleaning component includes a cleaning scraper that slides on the top of the filter screen, a waste scraper that slides on the inner side of the waste trough, and a drive rod hinged to the top surface of the cleaning scraper. The waste scraper is installed on the side wall of the cleaning scraper, and the cleaning scraper is installed on the periphery of the cleaning vehicle via the drive rod.

[0022] By adopting the above technical solution, the drive rod is installed on the periphery of the existing cleaning vehicle. When the cleaning vehicle cleans the road surface, the drive rod will drive the cleaning scraper and the waste scraper to slide along the length of the drainage ditch. During the movement of the cleaning scraper, it can push the garbage and impurities to the inside of the waste trough plate through its own inclined surface. The waste scraper pushes the garbage and impurities in the waste trough plate to the garbage collection bin.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During rainy or heavy rain, rainwater flows from the road surface to the drainage ditches on both sides of the road surface. After drainage, the curved strip rises vertically through the tension spring until the outer arc surface of the curved strip fits into the inner arc surface of the curved groove. This achieves the separation between the drainage ditch and the long water collection tank, minimizing the emission of unpleasant gases from the long water collection tank.

[0025] 2. Rainwater remaining inside the garbage collection bin flows into the bottom of the garbage collection bin through the filter screen body. The rainwater at the bottom of the garbage collection bin flows back to the drainage ditch through the water filtration holes. At this time, garbage and impurities are intercepted on the inside of the filter screen body.

[0026] 3. First, the drive rod is installed around the existing cleaning vehicle. When the cleaning vehicle cleans the road surface, the drive rod will drive the cleaning scraper and waste scraper to slide along the length of the drainage ditch. During the movement of the cleaning scraper, it can push the garbage and impurities to the inside of the waste trough through its own inclined surface. The waste scraper pushes the garbage and impurities in the waste trough to the garbage collection bin. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Reference Figure 1-3 As shown, a drainage pavement includes drainage ditches 12 constructed on the left and right sides of the pavement body 11, with the drainage ditches 12 extending along the length of the pavement body 11. A long, narrow water collection tank 13 is installed at the bottom of the drainage ditch 12 along its length, and both ends of the long, narrow water collection tank 13 are connected to the municipal drainage network via drainage pipes 14. An arc-shaped groove 16 is provided on the outer bottom surface of the drainage ditch 12 along its length, and the longitudinal section of the arc-shaped groove 16 is circular. A drainage slot 15 is provided on the inner bottom surface of the drainage ditch 12 along its length, and the drainage slot 15 penetrates the top of the long, narrow water collection tank 13, with the arc-shaped groove 16 connected to the drainage slot 15. An arc-shaped strip 17 slides vertically through the drainage slot 15 in the drainage ditch 12, with the outer arc surface of the arc-shaped strip 17 and the inner arc surface of the arc-shaped groove 16 fitting together.

[0034] Reference Figure 1-3 As shown, an arc-shaped strip 17 is located inside the elongated water collection tank 13. A reset strip 18 is provided in the drainage ditch 12 through the drainage opening 15. The two ends of the reset strip 18 are fixed to the two opposite inner walls of the drainage opening 15, and one reset strip 18 is provided at each end of the arc-shaped strip 17. A reset cylinder 19 is fixedly installed on the top of the reset strip 18. A reset rod 20 passes vertically through the inner side of the reset cylinder 19. A reset panel 21 is coaxially fixed to the periphery of the reset rod 20. A tension spring 22 is fixedly connected between the top surface of the reset panel 21 and the inner top surface of the reset cylinder 19. Both ends of the reset rod 20 pass through the reset cylinder 19, and the bottom end of the reset rod 20 is fixed to the outer arc surface of the arc-shaped strip 17. A ditch cover 23 is installed in the drainage ditch 12 through its top opening.

[0035] Reference Figure 1-3 As shown, a strip-shaped channel 24 is formed on the top of the ditch cover 23 along its length, and a flow-guiding groove 25 is formed on the top of the ditch cover 23 along its width. Flow-guiding grooves 25 are provided on both the left and right sides of the strip-shaped channel 24. Several flow-guiding grooves 25 are provided on both sides of the strip-shaped channel 24 along the length of the ditch cover 23. The inner bottom surface of the flow-guiding groove 25 is inclined from top to bottom along the direction close to the strip-shaped channel 24, and the position of the inner bottom surface of the flow-guiding groove 25 near the strip-shaped channel 24 is connected to the drainage ditch 12. Waste trough plates 26 are installed on the left and right inner sidewalls of the drainage ditch 12 along its length. Filter screen plates 27 are fixedly installed on the sidewalls of the two waste trough plates 26 that are close to each other. The filter screen plates 27 are inclined from bottom to top along the direction away from the waste trough plates 26.

[0036] Reference Figure 1-3 As shown, two filter screens 27 are fixedly connected to each other on their adjacent sidewalls. The waste trough plate 26 and the filter screen plate 27 are composed of filter wire mesh. The waste trough plate 26 and the filter screen plate 27 are located on the drainage ditch 12 near the ditch cover plate 23. The longitudinal section of the bottom of the drainage ditch 12 is a concave arc shape, and the drainage outlet 15 is located in the low-lying position at the bottom of the drainage ditch 12. Garbage collection cylinders 28 are provided on the inner side of the drainage ditch 12 near its left and right sides. The bottom end of the garbage collection cylinder 28 passes vertically through the bottom of the drainage ditch 12. The tops of the two garbage collection cylinders 28 pass through the two waste trough plates 26 respectively. The top surface of the garbage collection cylinder 28 is flush with the inner bottom surface of the corresponding waste trough plate 26, thereby allowing the garbage inside the waste trough plate 26 to slide smoothly into the inner side of the garbage collection cylinder 28.

[0037] Reference Figure 2-4As shown, both garbage collection bins 28 are positioned on the same side of the drainage ditch 12. Each garbage collection bin 28 has a filter screen cylinder 29 installed through an opening at its top. The filter screen cylinder 29 is composed of filter mesh and has an opening at its top. Water filtering holes 30 are provided around the bottom of the garbage collection bin 28, extending through the inner bottom surface of the drainage ditch 12 along its width. This allows the inner side of the garbage collection bin 28 to be connected to the bottom of the drainage ditch 12 through the water filtering holes 30. A cleaning scraper 31 is slidably mounted on the top surface of the filter screen plate 27 along its length.

[0038] Reference Figure 2-4 As shown, the cleaning scraper 31 is inclined from left to right along the side wall near the garbage collection bin 28 towards the waste trough plate 26. A waste scraper 32 slides along the length of the waste trough plate 26 on its inner side. Two waste scrapers 32 are fixed to the side walls of the two cleaning scrapers 31 that are far apart from each other, while the side walls of the two cleaning scrapers 31 that are close together are fixedly connected. A drive rod 33 passes through a strip-shaped groove 24 on the ditch cover plate 23. The bottom end of the drive rod 33 is hinged to the top surface of the cleaning scraper 31, and the top end of the drive rod 33 is detachably installed on the cleaning vehicle.

[0039] The implementation principle of a drainage pavement disclosed in this application embodiment is as follows: During rainy or heavy rain weather, rainwater from the pavement body 11 flows to the drainage ditches 12 on both sides of the pavement body 11. The rainwater is collected in the middle of the drainage ditch 12 through the guide grooves 25 of the ditch cover plate 23. The rainwater is filtered by the filter screen 27 and flows to the bottom of the drainage ditch 12. The garbage and impurities intercepted by the filter screen 27 and the waste trough plate 26 are directly stored at the top of the filter screen 27 and the waste trough plate 26. The rainwater collected in the middle of the drainage ditch 12 flows from the highest point of the filter screen 27 to the lowest point of the filter screen 27, thereby increasing the contact area between the rainwater and the filter screen 27 and thus improving the filtration efficiency of the filter screen 27.

[0040] Rainwater at the bottom of the drainage ditch 12 presses down on the curved plate 17 under its own weight, connecting the drainage ditch 12 to the elongated collection tank 13 through the drainage outlet 15. This allows rainwater to flow through the drainage outlet 15 at the bottom of the drainage ditch 12 to the inside of the elongated collection tank 13. The rainwater in the elongated collection tank 13 then flows into the municipal drainage network through the drainage pipe 14. After drainage is completed, the curved plate 17 rises vertically by the tension spring 22 until the outer curved surface of the curved plate 17 fits against the inner curved surface of the curved outlet 16, thus creating a barrier between the drainage ditch 12 and the elongated collection tank 13 and minimizing the emission of unpleasant gases from the elongated collection tank 13.

[0041] First, the drive rod 33 is installed around the existing cleaning vehicle. Then, when the cleaning vehicle cleans the road surface 11, the drive rod 33 drives the cleaning scraper 31 and the waste scraper 32 to slide along the length of the drainage ditch 12. During the movement of the cleaning scraper 31, it can push garbage and impurities to the inside of the waste trough 26 through its inclined surface. The waste scraper 32 pushes the garbage and impurities in the waste trough 26 to the garbage collection bin 28. The rainwater remaining in the garbage collection bin 28 flows into the bottom of the garbage collection bin 28 through the filter screen 29. The rainwater at the bottom of the garbage collection bin 28 flows back to the drainage ditch 12 through the water filter hole 30. At this time, the garbage and impurities are intercepted inside the filter screen 29.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
