  • the Chinese patent “Road Dust Collection and Drainage Canal” with the patent application No. 2017211526433 disclose an urban road drainage canal capable of automatically cleaning a road using natural wind, traffic stream whirlwind and rainwater, and automatically collecting and removing dust.
  • the present invention provides a new structure of the road dust collection and drainage canal based on the above invention advantages, which not only retains the advantages of the self-cleaning road in the above patent, but also has features of improved firmness, simple construction and maintenance, low construction cost and the like.
  • the present invention has the following advantages.
  • the present invention has another advantage of reducing an intensity of mechanical or manual road cleaning, and saving money for municipal administration.
  • the present invention has another advantage of effectively reducing gathered water on the road and effectively improving an impact resistance of the road, thus guaranteeing a driving safety.
  • the present invention has a further advantage that the road dust collection and drainage canal may be used after simple installation without additional fixing with cement mortar, is convenient for mechanized construction and maintenance, and is easily replaced as a wearing part.
  • the present invention is intended to design an urban road drainage canal having a self-cleaning function, especially automatically cleaning a road using natural wind, traffic stream whirlwind and rainwater, and automatically collecting and removing dust.
  • a road dust collection and drainage canal includes a drainage ditch and a cover plug that covers the drainage ditch, wherein the drainage ditch is used for collecting dust, debris and rainwater on a road, and the cover plug is higher than a road surface and plays a role of a curbstone or a road edge stone, so as to guarantee that a motor vehicle runs in a motor vehicle lane.
  • the cover plug should take into account an effect of the curbstone, should be subjected to an impact force in a horizontal right direction of a vehicle, and should also be subjected to a downward rolling force of the vehicle, and meanwhile, an impact force to a left end of the cover plug under braking of the vehicle also includes a vertically upward impact force component, and the vertically upward force enables the cover plug to rotate clockwise around a force bearing point at a right end.
  • a road edge of a road surface is provided with a dust collection and drainage canal
  • the dust collection and drainage canal is composed of a U-shaped drainage ditch adjacent to the road edge and a cover plug that covers the drainage ditch
  • a side surface of the cover plug is in a T-shape
  • a cover plug head is embedded in the drainage ditch
  • cover plug shoulders are supported on platforms formed by left and right ditch walls of the drainage ditch to bear a weight of the whole cover plug
  • a front surface of the cover plug is in an inverted U-shape, a semi-open cavity formed by the inverted U-shape forms a dust absorption channel with an entity of the drainage ditch, the dust absorption channel communicates the drainage ditch with an external space, and dust and debris on a road get into and fall into a bottom of the drainage ditch from the external space through the dust absorption channel under driving of an external force.
  • solution 2 the front surface of the cover plug is in the inverted U-shape, and a concave extent is gradually decreased on a cross section of the inverted U-shape from left to right or from front to back.
  • the side surface of the cover plug is in the T-shape, may be symmetrical or asymmetrical, and is matched with a symmetry of the U-shaped drainage ditch.
  • a size of the cover plug head is matched with a size of the drainage ditch, so as to reduce a left-right shaking amplitude of the cover plug, and bear or transmit an impact force from a vehicle on a road to a horizontal component force of the cover plug.
  • Embodiment 1 of the present invention the embodiment is described with reference to Fig. 1 , Fig. 2 , Fig. 3 and Fig. 4 .
  • a road edge of a road surface 2 is provided with a road dust collection and drainage canal 1 adjacent to a flatstone 5, and the road dust collection and drainage canal 1 is composed of two major parts including a U-shaped drainage ditch 11 adjacent to the road edge and a cover plug 10 that covers the drainage ditch 11.
  • the drainage ditch 11 may be built with cement or cast with cement in situ before laying the road surface 2 and the flatstone 5.
  • the drainage ditch 11 is cast into a U-shape, platforms 11C on a left wall and a right wall thereof are generally symmetrical or asymmetrical, and a symmetrical mode is used in the embodiment.
  • the platforms 11C are as high as the road surface or the flatstone 5.
  • a pressure from the road surface caused by a vehicle running on the road surface enables the flatstone 5 to abut against the left wall of the drainage ditch 11, as shown in Fig. 2 , and a cover plug head 10b of the cover plug 10 is embedded in the drainage ditch 11. Therefore, the pressure is transmitted to the right wall of the drainage ditch 11, then is borne by a cushion layer 14 and a non-motor vehicle road surface 13, and finally reaches the soil.
  • a side view of the cover plug 10 is in a T-shape
  • the cover plug head 10b is a convex head
  • cover plug shoulders 10c are convex shoulders.
  • the cover plug head 10b is embedded in the drainage ditch 11, and the cover plug shoulders 10c are supported on the platforms on the left wall and the right wall of the drainage ditch 11 to bear a weight of the whole cover plug 10.
  • a front view of the cover plug 10 is in an inverted U-shape, and an entity of the inverted U-shape forms a dust absorption channel 10a with an entity part of the drainage ditch.
  • the dust absorption channel 10a communicates the drainage ditch 11 with an external space, and dust 16 and debris on the road surface 2 get into and fall into a bottom of the drainage ditch 11 from the external space through the dust absorption channel 10a under driving of an external force such as wind, rainwater and the like.
  • a cross section of the cover plug 10 basically tends to increase in area from left to right, which on one hand is beneficial for the cover plug 10 to bear a larger downward pressure, which is namely a rolling force of the vehicle, and on the other hand is beneficial for maintaining a stability of the cover plug 10 itself without additional reinforcement due to increase of the weight of the cover plug 10 itself.
  • the dust absorption channel 10a has a narrow area, and a minimum size thereof determines a diameter of smallest debris capable of entering the area, thus preventing too many large-sized objects from entering the drainage ditch 11.
  • the cover plug head 10b is longer, a larger part of the cover plug head 10b is embedded in the drainage ditch 11, and the cover plug 10 is more stable, so that the cover plug 10 is more capable of withstanding an impact of an external force from the vehicle and the like.
  • a height of the cover plug head 10b is equal to that of the common curbstone, which is 150 mm, and a depth of the drainage ditch 11 is more than 300 mm, a better effect is achieved.
  • a size of the cover plug head 10b may be smaller than that of the drainage ditch 11 by 1 mm.
  • cover plug head 10b has a symmetrical shape in the embodiment, the cover plug head 10b may also be asymmetrical, as long as the cover plug head 10b is matched with a symmetry of the U-shaped drainage ditch 11.
  • a large amount of dust and debris may accumulate in a drainage channel 11a contained in the drainage ditch 11, and get into a sand sediment trap 20 under an impact of rainwater. In the case of too much debris in the trap, a trap cover 20c may be opened for cleaning.
  • the drainage ditch 11 is cast with concrete in situ, built with stone, or built with brick and concrete.
  • the cover plug 10 is prefabricated with concrete, including resin concrete, and may also be cast with cast iron.
  • the implementation of the present invention can effectively reduce road dust pollution and guarantee a driving safety and a pedestrian safety on the road.
  • Embodiment 2 of the present invention the embodiment is described with reference to Fig. 1 , Fig. 5 , Fig. 6 and Fig. 4 .
  • a drainage ditch 11 is cast into a
  • U-shape, and platforms 11C on a left wall and a right wall thereof are not as high as a road surface or a flatstone 5, but are lower than the road surface or the flatstone 5.
  • Such a structure makes the flatstone 5 directly abut against a front surface of a cover plug 10, and directly transmits a horizontal force from a vehicle to a cushion layer 14 and a non-motor vehicle road surface 13, and finally transmits the horizontal force to the soil, thus effectively protecting the drainage ditch 11 from being easily damaged.
  • the cover plug 10 be can further fixed with cement mortar 15 to make up or partially make up for a deficiency that a cover plug head 10b is embedded in the drainage ditch 11 in a shallower manner.
  • a dust absorption channel 10a also has a narrower area, and a minimum size thereof determines a diameter of smallest debris capable of entering the area, thus preventing too many large-sized objects from entering the drainage ditch 11.
  • the narrower area is much larger, and a size of debris allowed to enter the area is much larger. Therefore, a grid or a mesh may be arranged in the dust absorption channel 10a to prevent debris or objects of certain sizes from entering the drainage ditch 11.
  • Fig. 4 is used as a stereoscopic view of the cover plug 10 in the embodiment.
  • Embodiment 3 of the present invention the embodiment is described with reference to Fig. 1 , Fig. 7 , Fig. 8 and Fig. 9 .
  • An inner cavity of a cover plug 10 in the embodiment is larger, which may save materials, is light in weight and easy to construct, but has a poor strength and a poor impact and pressure resistance compared with the above two examples.
  • a dust absorption channel 10a almost has no narrower area to prevent too many large-sized objects from entering a drainage ditch 11. Therefore, a grid or a mesh may be arranged in the dust absorption channel 10a to prevent debris or objects of certain sizes from entering the drainage ditch 11.
  • the cover plug 10 is changed from the U-shape to a circular arch shape in the front view; and a part of the inverted T-shape is cut out in the side view to be concave, so as to save materials, etc.
  • the inventor also believes that the cover plug 10 is essentially a cover plug structure, which is a cover and a plug with respect to the drainage ditch 11. No matter what shape the drainage ditch is or how the cover plug 10 is changed, the cover plug structure is essential.
