Embodiment 1 of the present invention: the embodiment is described with reference toFig. 1 ,Fig. 2 ,Fig. 3 andFig. 4 . - According to a road dust collection and drainage canal of the present invention, a road edge of a
road surface 2 is provided with a road dust collection anddrainage canal 1 adjacent to aflatstone 5, and the road dust collection anddrainage canal 1 is composed of two major parts including a U-shapeddrainage ditch 11 adjacent to the road edge and acover plug 10 that covers thedrainage ditch 11. Thedrainage ditch 11 may be built with cement or cast with cement in situ before laying theroad surface 2 and theflatstone 5. Thedrainage 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. Moreover, theplatforms 11C are as high as the road surface or theflatstone 5. A pressure from the road surface caused by a vehicle running on the road surface enables theflatstone 5 to abut against the left wall of thedrainage ditch 11, as shown inFig. 2 , and acover plug head 10b of thecover plug 10 is embedded in thedrainage ditch 11. Therefore, the pressure is transmitted to the right wall of thedrainage ditch 11, then is borne by acushion layer 14 and a non-motorvehicle road surface 13, and finally reaches the soil. - As shown in
Fig. 3 , a side view of thecover plug 10 is in a T-shape, thecover plug head 10b is a convex head, andcover plug shoulders 10c are convex shoulders. Thecover plug head 10b is embedded in thedrainage ditch 11, and thecover plug shoulders 10c are supported on the platforms on the left wall and the right wall of thedrainage ditch 11 to bear a weight of thewhole cover plug 10. Moreover, a front view of thecover plug 10 is in an inverted U-shape, and an entity of the inverted U-shape forms adust absorption channel 10a with an entity part of the drainage ditch. Thedust absorption channel 10a communicates thedrainage ditch 11 with an external space, anddust 16 and debris on theroad surface 2 get into and fall into a bottom of thedrainage ditch 11 from the external space through thedust absorption channel 10a under driving of an external force such as wind, rainwater and the like. - As shown in
Fig. 2 andFig. 3 , a cross section of thecover plug 10 basically tends to increase in area from left to right, which on one hand is beneficial for thecover 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 thecover plug 10 itself without additional reinforcement due to increase of the weight of thecover 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 thedrainage ditch 11. - Generally, if the
cover plug head 10b is longer, a larger part of thecover plug head 10b is embedded in thedrainage ditch 11, and thecover plug 10 is more stable, so that thecover plug 10 is more capable of withstanding an impact of an external force from the vehicle and the like. For example, when a height of thecover plug head 10b is equal to that of the common curbstone, which is 150 mm, and a depth of thedrainage ditch 11 is more than 300 mm, a better effect is achieved. The smaller the clearance fit between thecover plug head 10b and thedrainage ditch 11 is, the better the effect is, which can prevent thecover plug head 10b from shaking left and right. Generally, a size of thecover plug head 10b may be smaller than that of thedrainage ditch 11 by 1 mm. - Although the
cover plug head 10b has a symmetrical shape in the embodiment, thecover plug head 10b may also be asymmetrical, as long as thecover plug head 10b is matched with a symmetry of the U-shapeddrainage 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. Thecover 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 toFig. 1 ,Fig. 5 ,Fig. 6 andFig. 4 . - Compared with
Embodiment 1, in this embodiment, adrainage 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 aflatstone 5, but are lower than the road surface or theflatstone 5. Such a structure makes theflatstone 5 directly abut against a front surface of acover plug 10, and directly transmits a horizontal force from a vehicle to acushion layer 14 and a non-motorvehicle road surface 13, and finally transmits the horizontal force to the soil, thus effectively protecting thedrainage ditch 11 from being easily damaged. Moreover, after constructing and installing thecover plug 10 in place, thecover plug 10 be can further fixed withcement mortar 15 to make up or partially make up for a deficiency that acover plug head 10b is embedded in thedrainage 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 thedrainage ditch 11. However, it is very obvious that compared withEmbodiment 1, 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 thedust absorption channel 10a to prevent debris or objects of certain sizes from entering thedrainage ditch 11. -
Fig. 4 is used as a stereoscopic view of thecover plug 10 in the embodiment. - The rest is the same as in
Embodiment 1. - Embodiment 3 of the present invention:
the embodiment is described with reference toFig. 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 adrainage ditch 11. Therefore, a grid or a mesh may be arranged in thedust absorption channel 10a to prevent debris or objects of certain sizes from entering thedrainage ditch 11. - The rest is the same as in
Embodiment - All these embodiments merely illustrate a part of the present invention, and cannot be exhaustive. Those skilled in the art have various technical means to make modifications. For example, 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 thecover plug 10 is essentially a cover plug structure, which is a cover and a plug with respect to thedrainage ditch 11. No matter what shape the drainage ditch is or how thecover plug 10 is changed, the cover plug structure is essential.
