Description

Technical Field

[0001] The present application relates to the technical field of pavement drainage structures, and in particular to a drainage pavement structure and a construction process thereof. Background Art

[0002] With the continuous advancement of urbanization, urban road traffic facilities have been significantly developed. Roads not only bear the function of traffic, but also must have good drainage performance to ensure driving safety and pedestrian convenience. To this end, modern urban roads are generally equipped with various forms of drainage systems, which are designed to effectively collect and drain road surface water and prevent various safety hazards caused by rainwater accumulation.

[0003] In existing pavement drainage structures, it is common practice to set steps at the edge of the roadbed and arrange drainage outlets on the side walls of the steps to guide the accumulated water on the road surface to the underground drainage tank. In addition, the drainage pipes are usually evenly distributed along the length of the roadbed, and rainwater is collected and transported by connecting the drainage tanks. Although this design can basically meet daily drainage needs, there are still some shortcomings in its specific implementation. For example, in order to ensure drainage efficiency, the drainage outlets are generally arranged more densely, but this also increases the difficulty of maintenance. Especially in the rainy season, as fallen leaves, paper scraps and other debris enter the drainage system with the water flow, it is easy to cause the drainage outlet to be blocked, seriously affecting the normal operation of the system.

[0004] To address the above issues, the main measures currently taken include regular cleaning of drainage ditches and the addition of physical barriers such as filters to intercept large pieces of garbage. However, these methods often only treat the symptoms and not the root cause, and cannot fundamentally solve the problem. Especially in high-flow areas or under continuous heavy rainfall conditions, manual intervention is difficult to respond in time, resulting in a significant decrease in drainage efficiency. Therefore, how to improve the self-cleaning ability of the drain outlet and reduce the frequency of manual intervention has become a key technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to reduce the impact of debris accumulation on drainage efficiency at a drain outlet, the present application provides a drainage pavement structure and a construction process thereof.

[0006] In the first aspect, the present application provides a drainage pavement structure and a construction process thereof using the following technical solutions: A drainage pavement structure comprises a roadbed and steps are arranged at the edge of the roadbed, a plurality of drainage bins are arranged inside the roadbed at the edge, a plurality of drainage outlets are arranged on the side walls of the steps, the drainage outlets are connected with the drainage bins, drainage pipes are arranged between adjacent drainage bins, fences are arranged at the drainage outlets, a fan-shaped tool is rotatably arranged inside the drainage bin, the cutting edge of the fan-shaped tool is fitted with the fence, a lifting hole is arranged on the surface of the roadbed, a speed bump is arranged in the lifting hole, a reset elastic member is arranged between the inner wall of the lifting hole and the speed bump, and a transmission mechanism for driving the fan-shaped tool to rotate is arranged between the speed bump and the fan-shaped tool.

[0007] By adopting the above technical solution, it is possible to effectively prevent leaves and other debris from entering the drainage bin when rainwater flows into the drain outlet, and at the same time use the rotating fan-shaped cutter to cut the debris accumulated at the fence to prevent the debris from clogging the drain outlet and improve drainage efficiency. In addition, the design of the speed bump can not only slow down the vehicle speed, but also generate downward pressure when the vehicle passes by, drive the transmission mechanism to work, and ensure that the fan-shaped cutter continues to effectively remove debris. The setting of the reset elastic member ensures that the speed bump automatically returns to its original position when there is no external pressure, extending its service life.

[0008] Preferably, the transmission mechanism includes a transmission rod, a driving wheel, a driven wheel and a transmission belt, the transmission rod is connected to the speed reduction belt, the driving wheel is rotatably connected inside the drainage bin and the transmission rod is in contact with the driving wheel, the driven wheel is connected to the fan-shaped cutter and is coaxially arranged, and the transmission belt is wound between the driving wheel and the driven wheel.

[0009] By adopting the above technical solution, this design enables that when a vehicle passes over a speed bump, the speed bump moves downward and drives the driving wheel to rotate through the transmission rod, and then transmits power to the driven wheel through the transmission belt, thereby driving the fan-shaped cutter to rotate, effectively chopping up leaves and other debris accumulated at the fence, preventing the drain outlet from being blocked, and improving drainage efficiency.

[0010] Preferably, the transmission rod is rotatably provided with a pawl, the driving wheel is connected to a coaxially arranged ratchet, the pawl is meshed with the ratchet, and a tightening elastic member for pushing the pawl toward the ratchet is connected between the transmission rod and the pawl.

[0011] By adopting the above technical solution, the speed reduction belt and the transmission rod will drive the ratchet and the driving wheel to rotate when they go down, thereby realizing the rotation of the driven wheel and the fan-shaped tool. When the speed reduction belt is reset and moves upward, the driving wheel and the fan-shaped tool will not be reset, thereby realizing the unidirectional rotation of the fan-shaped tool during the reciprocating up and down process of the speed reduction belt.

[0012] Preferably, the inner side of the transmission belt is evenly distributed with anti-skid grooves, the length direction of the anti-skid grooves is arranged along the width direction of the transmission belt, and the side walls of the driving wheel and the driven wheel are both provided with a plurality of anti-skid ridges, and the anti-skid ridges are adapted to the anti-skid grooves.

[0013] By adopting the above technical solution, the friction between the transmission belt and the driving wheel and the driven wheel is significantly increased, effectively preventing the occurrence of slippage and ensuring the stability and reliability of the transmission system. At the same time, the design of anti-skid grooves and anti-skid edges improves transmission efficiency, reduces energy loss, and extends the service life of the transmission belt.

[0014] Preferably, both the driving wheel and the driven wheel are provided with anti-slip rings, and the transmission belt is located inside the anti-slip rings.

[0015] By adopting the above technical solution, the setting of the anti-drop ring effectively prevents the transmission belt from falling off during operation, improves the stability of the transmission system, and ensures that the fan-shaped cutter can continuously and effectively chop debris such as leaves accumulated at the fence, thereby ensuring the smooth flow of the drainage outlet.

[0016] Preferably, a limit frame is further provided inside the drainage bin, the transmission belt passes through the limit frame, and a tensioning elastic member is connected between the drainage bin and the limit frame.

[0017] By adopting the above technical solution, the cooperation between the limit frame and the transmission belt ensures the stability of the transmission belt during operation and prevents it from deflecting or falling off. The setting of the tensioning elastic member enables the transmission belt to always maintain an appropriate tension state, effectively reducing the slippage caused by relaxation and improving the transmission efficiency and reliability. At the same time, this design also helps to extend the service life of the transmission belt.

[0018] Preferably, the limit frame is slidably connected to the drainage bin, the limit frame is provided with a mounting hole, a limit ball is provided in the mounting hole, the limit ball and the mounting hole are movably connected, a push plate is provided at the end of the tensioning elastic member, the push plate covers the mounting hole to push the limit ball toward the transmission belt, and the limit ball is inserted into the anti-slip groove.

[0019] By adopting the above technical solution, the limiting ball in the limiting frame can be inserted into the anti-skid groove of the transmission belt under the action of the tensioning elastic member. In the initial stage of the transmission belt being stressed, it is necessary to overcome the force of the tensioning elastic member and allow the limiting ball to exit the anti-skid groove, so that the transmission belt is stressed but does not move in the initial stage of changing from static to rotating, and then rotates more rapidly when a certain stress threshold is reached. This design not only maintains the tension state of the transmission belt, but also increases the acceleration of the transmission belt in the starting stage, thereby enhancing the chopping effect of the fan-shaped cutter on debris such as leaves.

[0020] Preferably, the speed bump includes a stress-bearing section and a buffer section connected at the top, the buffer section is located at the end of the speed bump and connected to the transmission rod, the stress-bearing section is located in the middle of the speed bump and a buffer groove is provided between the stress-bearing section and the buffer section, and the buffer groove opening is arranged downward.

[0021] By adopting the above technical solution, the design of speed bumps divided into a force-bearing section and a buffer section can effectively protect the transmission mechanism during vehicle driving. Specifically, when the vehicle passes through the force-bearing section, a downward pressure action is first generated, and then gradually transmitted to the buffer section, thereby reducing the damage of the instantaneous impact force to the entire system. At the same time, the existence of the buffer groove further optimizes this process, ensures a smooth transition of force, and improves the stability and durability of the system operation.

[0022] Preferably, the force-bearing section and the buffer section are both provided with a plurality of adjustment holes, and the plurality of adjustment holes are respectively located on both sides of the buffer groove; an adjustment rod is connected between the force-bearing section and the buffer section, and the adjustment rod is U-shaped and both ends are respectively inserted into the corresponding adjustment holes.

[0023] By adopting the above technical solution, the design of the adjustment hole and the adjustment rod realizes the adjustment of the actual opening size or opening depth of the buffer groove, so as to flexibly control the degree and speed of buffering. When the buffer groove opening is larger and the opening depth is deeper, the buffering effect is stronger, which effectively avoids the damage of parts caused by excessive force and improves the stability and durability of the system. At the same time, this design can be personalized according to different road conditions and usage requirements, which enhances the adaptability and practicality of the product.

[0024] In a second aspect, the present application provides a drainage pavement construction process, which adopts the following technical solution: A drainage pavement construction process, which includes digging grooves at the edge of the roadbed to lay drainage pipes, reserving drainage bins at intervals along the arrangement direction of the drainage pipes, backfilling the road sections between adjacent drainage bins, laying floor tiles on top of the drainage bins to form steps, reserving drainage holes and installing fences when laying the steps.

[0025] By adopting the above technical solution, the drainage pavement construction process can effectively improve the reliability of the drainage system. Specifically: - Dig grooves at the edge of the roadbed to lay drainage pipes to ensure that rainwater can be quickly discharged through the preset path to reduce water accumulation.

[0026] - Drainage bins are reserved at intervals along the layout of the drainage pipes to collect and store rainwater and prevent a large amount of rainwater from instantly rushing into the main drainage system and causing blockage.

[0027] - The road sections between adjacent drainage bins are backfilled to ensure the flatness and stability of the entire road surface without affecting the drainage function.

[0028] - Laying tiles on top of the drainage bin to form steps is both aesthetically pleasing and practical, making it easier for pedestrians to pass through.

[0029] - Leaving drainage holes and installing fences when laying steps can effectively intercept large debris and prevent it from entering the drainage system, extending the service life of the system.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use the rotating fan-shaped cutter to chop up the leaves and other debris accumulated at the fence, thereby effectively preventing the debris from clogging the drain outlet and improving the drainage efficiency; 2. When the speed reduction belt and the transmission rod go downward, they drive the ratchet and the driving wheel to rotate, realizing the one-way rotation of the driven wheel and the fan-shaped cutter, ensuring that the cleaning mechanism can be effectively activated every time a vehicle passes by, enhancing the self-cleaning ability and reducing the frequency of manual intervention; 3. Anti-skid grooves and anti-skid edges are set on the transmission belt, and the cooperation of the limit ball and the tension elastic part realizes the smooth acceleration of the transmission belt at the starting stage, further improving the chopping effect of the fan-shaped knife and making it more stable.

[0032] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0033] The inventor of this application found that with the development of urbanization, more and more roads are being built in cities. For the safety of roads and the convenience of pedestrians on the road, drainage outlets are set up on the roads. When it rains, rainwater is discharged in time through the drainage outlets so that rainwater does not accumulate on the road surface. Therefore, drainage devices are an indispensable part of road construction. However, when accumulated water flows to the drainage outlet, it usually carries fallen leaves and other debris. When the debris accumulates, it is easy to block the drainage outlet, thereby affecting the drainage efficiency. To this end, this application mainly adopts the following scheme: Example Reference Figure 1 The drainage pavement structure provided in the embodiment of the present application includes a roadbed 1, and a step 11 is arranged at the edge of the roadbed 1 in the width direction. In actual scenarios, the step 11 can be set on one side or on both sides. This embodiment takes the setting on both sides as an example. The surface of the roadbed 1 is also provided with a plurality of speed bumps 3, and the speed bumps 3 are arranged along the width direction of the roadbed 1.

[0034] Reference Figure 2 A plurality of hollow drainage chambers 10 are also provided inside the edge of the roadbed 1 in the width direction. The plurality of drainage chambers 10 are evenly distributed along the length direction of the roadbed 1, and drainage pipes 13 are provided between adjacent drainage chambers 10. The step 11 is located above the drainage chamber 10, and a drainage port 110 is provided on the side of the portion of the step 11 that is higher than the roadbed 1. Each drainage chamber 10 corresponds to a drainage port 110 and is connected to each other, so as to achieve uniform drainage of the roadbed 1 at all locations.

[0035] A fence 14 is installed at the drain outlet 110. In this embodiment, the fence 14 includes a frame and a wire mesh fixed thereon. The mesh size of the wire mesh can be adjusted according to actual conditions, so as to block larger debris without affecting the smooth flow of water. In addition to the wire mesh, other high-strength fiber meshes can be used as alternative materials in other embodiments to meet the use requirements in different environments.

[0036] A fan-shaped cutter 2 is also rotatably arranged inside the drainage bin 10, and the fan-shaped cutter 2 includes a rotating shaft and a plurality of blades welded thereon. The rotating shaft is installed on the side of the drainage bin 10 to ensure its smooth rotation. The blade can be designed to be serrated or straight. The former is suitable for cutting off harder branches and other debris, while the latter is more suitable for processing soft leaves. In addition, composite materials can also be used to make the blades, which can reduce weight while ensuring strength and improve operating efficiency. The cutting edge of each blade fits against the fence 14. The rotation of the fan-shaped cutter 2 can shred the part of the leaves stuck in the mesh of the fence 14 that extends into the drainage bin 10, thereby alleviating the situation where the leaves continue to be stuck to a certain extent.

[0037] The actual installation method of the speed bump 3 is as follows: a lifting hole 12 is excavated on the surface of the roadbed 1, and the speed bump 3 is located inside the lifting hole 12 and can slide up and down. When a vehicle passes through the speed bump 3, the speed bump 3 can be pressed down. A reset elastic member 121 is also connected between the bottom wall of the lifting hole 12 and the bottom wall of the speed bump 3. In this embodiment, the reset elastic member 121 is a spring, so that after the vehicle passes through the speed bump 3, the reset elastic member 121 can be used to restore the elastic force of the deformation to realize the upward movement and reset of the speed bump 3. A transmission mechanism 4 for driving the fan-shaped tool 2 to rotate is provided between the speed bump 3 and the fan-shaped tool 2.

[0038] Reference Figure 3 The speed bump 3 includes a force-bearing section 31 and a buffer section 32 connected at the top. A buffer groove 30 is provided between the force-bearing section 31 and the buffer section 32. The buffer groove 30 is opened downward, which can play a shock-absorbing role when the vehicle is rolling over, avoiding excessive impact on subsequent transmission mechanism 4 and other parts. The force-bearing section 31 and the buffer section 32 are provided with a plurality of adjustment holes 330 on both sides of the buffer groove 30. The plurality of adjustment holes 330 are evenly distributed along the opening direction of the buffer groove 30. The force-bearing section 31 and the buffer section 32 are connected on both sides of the buffer groove 30 through an adjustment rod 33. The adjustment rod 33 is U-shaped. The "suturing" of the buffer groove 30 is achieved by inserting the two ends of the adjustment rod 33 into the corresponding adjustment holes 330. By adjusting the adjustment holes 330 at different positions where the adjustment rod 33 is inserted, the actual opening size or opening depth of the buffer groove 30 can be adjusted, thereby adjusting the degree and speed of buffering. When the buffer groove 30 has a larger opening and a deeper opening, the buffering effect is stronger, thereby achieving on-demand adjustment of the buffering effect.

[0039] Reference Figure 4 and Figure 5The transmission mechanism 4 includes a transmission rod 41, a driving wheel 42, a driven wheel 43 and a transmission belt 44. The transmission rod 41 is connected to the buffer section 32 of the speed reduction belt 3. When the vehicle passes over the speed reduction belt 3, the force section 31, the buffer section 32 and the transmission rod 41 are driven downward in sequence. The driving wheel 42 is rotatably arranged inside the drainage bin 10 via a rotating shaft, and a ratchet 46 is fixedly arranged on the side wall of the driving wheel 42. The ratchet 46 is coaxial with the driving wheel 42. A ratchet 45 is rotatably arranged on the side wall of the transmission rod 41 via a rotating shaft, and the tip of the ratchet 45 abuts against the ratchet 46 to realize the unidirectional rotation of the ratchet 46 and the driving wheel 42 during the reciprocating movement of the transmission rod 41. A tightening elastic member 47 is also connected between the transmission rod 41 and the pawl 45. In this embodiment, the tightening elastic member 47 is a spring, so that the pawl 45 has a tendency to rotate toward the ratchet 46 at all times until it fits together, so that the ratchet 46 and the driving wheel 42 can still be stably pushed to rotate when the transmission rod 41 goes down next time.

[0040] The driven wheel 43 is fixedly connected to the fan-shaped tool 2 and is coaxially arranged. The transmission belt 44 is wound around the outside of the driving wheel 42 and the driven wheel 43. The diameter of the driving wheel 42 is larger than the diameter of the driven wheel 43, and the diameter of the driving wheel 42 is larger than the diameter of the ratchet 46. This expands the influence of the small stroke of the transmission rod 41 on the fan-shaped tool 2 and realizes the unidirectional and rapid rotation of the fan-shaped tool 2.

[0041] Reference Figure 6 In order to improve the stability of the transmission between the transmission belt 44 and the driving wheel 42 and the driven wheel 43, the present application is uniformly provided with anti-skid grooves 480 on the inner side of the transmission belt 44. The side walls of the driving wheel 42 and the driven wheel 43 are both provided with anti-skid edges 48, and the anti-skid edges 48 are adapted to the anti-skid grooves 480. This can not only increase the friction force and prevent slipping, but also improve the transmission efficiency. In addition, a pair of anti-slip rings 49 are provided on the driving wheel 42 and the driven wheel 43, and the transmission belt 44 is located on the inner side of the two anti-slip rings 49 to prevent the transmission belt 44 from falling off, further improving the stability of the transmission system.

[0042] Reference Figure 7In order to achieve the tensioning of the transmission belt 44, a limit frame 5 is also slidably arranged inside the drainage bin 10. The limit frame 5 is slidably connected to the drainage bin 10 through a sliding groove, and a mounting hole 52 is penetrated on one side of the limit frame 5. A limit ball 51 is placed in the mounting hole 52. The limit ball 51 is movably connected to the mounting hole 52, that is, the limit ball 51 can slide and rotate in the mounting hole 52. The transmission belt 44 has a section of anti-skid groove 480 that passes through the limit frame 5 and is located in the limit frame 5, which can be inserted by the limit ball 51. In order to allow the limit ball 51 to stably abut against the anti-skid groove 480, the present application provides a push plate 53 on the outside of the limit frame 5. The push plate 53 fits the outer wall of the limit frame 5 and the push plate 53 covers the opening of the mounting hole 52. In order to achieve the tightening of the transmission belt 44, the present application sets a tensioning elastic member 54 inside the drainage chamber 10. In this embodiment, the tensioning elastic member 54 is a spring. The tensioning elastic member 54 is connected between the inner wall of the drainage chamber 10 and the push plate 53. The tensioning elastic member 54 is in a compressed state to push the push plate 53 toward the limit frame 5, thereby achieving the stable abutment between the limit ball 51 and the anti-skid groove 480. In this state, the transmission belt 44 is tightened on the one hand, and the limit ball 51 temporarily locks the transmission belt 44 on the other hand. In the initial stage of the transmission belt 44 being stressed, the driving force required to overcome the force of the tensioning elastic member 54 and allow the limit ball 51 to exit the anti-skid groove 480, so that the transmission belt 44 is stressed but not moving at the initial stage of changing from static to rotation, and then rotates more rapidly after reaching a certain stress threshold. Through such a design, the acceleration of the transmission belt 44 in the starting stage can be achieved under the premise of maintaining the tension of the transmission belt 44, so that the fan-shaped cutter 2 can have a better effect of chopping debris such as leaves.

[0043] In addition, in other embodiments, in order to further improve the reliability and safety of the system, an electromagnetic clutch may be provided at the connection between the transmission rod 41 and the speed bump 3. The electromagnetic clutch may automatically control whether the power of the transmission rod 41 is transmitted or not according to the speed of the next vehicle. When the vehicle speed exceeds a preset value, the electromagnetic clutch is disconnected and the transmission is stopped to prevent excessive wear. This design can not only protect the transmission system from damage, but also improve the response speed and flexibility of the system.

[0044] In addition, in order to further improve the drainage stability, in other embodiments, a spray device may be added near the fence 14. The spray device includes a high-pressure water pump and a nozzle. The nozzle may be arranged inside the drainage chamber 10 to spray from the inside out toward the fence 14 to achieve reverse flushing. When a large amount of debris is detected to be accumulated at the fence 14, the high-pressure water pump is started, or it may be started at a fixed time, and a high-pressure water column is sprayed through the nozzle to disperse the debris. This method can greatly improve the dredging efficiency, especially in heavy rain weather.

[0045] In other embodiments, an intelligent monitoring system may be added to the drainage pipeline. The intelligent monitoring system includes sensors, controllers, and wireless communication modules. Sensors are installed at key locations of each drain outlet 110 and drainage pipeline 13 to monitor water flow and debris accumulation in real time. The controller automatically adjusts the automatic start cycle or intensity of the injection device based on the data fed back by the sensor to achieve automatic adjustment. The wireless communication module is responsible for transmitting data to the central monitoring center so that the staff can remotely monitor and manage the entire drainage system.

[0046] The implementation principle of this embodiment is: when rainwater flows into the drain outlet 110, the fence 14 can become the first line of defense, effectively blocking leaves and other debris from entering the drain bin 10. Of course, some debris will partially pass through the fence 14 to form an obstacle. The speed bump 3 provided in this application is an automatic lifting type. When the vehicle passes through the speed bump 3, the speed bump 3 will be pressed down, and the speed bump 3 can eventually be reset upward under the action of the reset elastic member 121, and the speed bump 3 can be moved up and down by the vehicle. When the speed bump 3 and the transmission rod 41 go down, they will drive the ratchet 46 and the driving wheel 42 to rotate, thereby realizing the rotation of the driven wheel 43 and the fan-shaped cutter 2. When the speed bump 3 is reset and moves upward, the driving wheel 42 and the fan-shaped cutter 2 are not reset, thereby realizing the unidirectional rotation of the fan-shaped cutter 2 in the process of the speed bump 3 moving up and down, thereby realizing the shearing of the debris after the fan-shaped cutter 2 extends into the fence 14. In addition, the tensioning method of the present application is not only able to achieve tensioning. At the initial stage when the transmission belt 44 is subjected to force, the driving force required to be able to overcome the force of the tensioning elastic member 54 and allow the limiting ball 51 to exit the anti-slip groove 480, so that the transmission belt 44 is first subjected to force but does not move at the initial stage when it changes from static to rotation, and then rotates more rapidly after reaching a certain force threshold. Through such a design, the acceleration of the transmission belt 44 in the starting stage can be achieved while maintaining the tension of the transmission belt 44, so that the fan-shaped tool 2 can have a better effect in chopping debris such as leaves.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
