Road gutter having dust collection function

Abstract

A road gutter having a dust collection function, consisting of a gutter groove (11) and a cover stopper (10) that covers the gutter groove (11). The side surface of the cover stopper (10) is “T”-shaped. Plugs (10b) of the cover stopper (10) are embedded in the gutter groove (11), and a shoulder (10c) of the cover stopper (10) is supported on platforms (11c) formed by the left and right walls of the gutter groove (11) to bear the weight of the whole cover stopper (10). The front surface of the cover stopper (10) is inverted “U”-shaped, and forms a dust absorption channel (10a) with a solid part of the gutter groove (11). The dust absorption channel (10a) communicates the gutter groove (11) with an external space. Road dust and mess enter the gutter groove (11) from the external space by means of the dust absorption channel (10a) under the drive of an external force, and fall to the bottom of the gutter groove (11).

What is claimed is: 
     
         1 . A road dust collection and drainage canal, wherein the dust collection and drainage canal is for disposition at a roadside edge of a road surface, the dust collection and drainage canal comprises a drainage ditch 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, and cover plug shoulders are supported on platforms formed by left and right ditch walls of the drainage ditch to bear a weight of the cover plug; and a front surface of the cover plug is in an inverted U-shape and forms a dust absorption channel with a part of the drainage ditch, the dust absorption channel provides communication between the drainage ditch and 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. 
     
     
         2 . The road dust collection and drainage canal according to  claim 1 , wherein 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. 
     
     
         3 . The road dust collection and drainage canal according to  claim 1 , wherein the side surface of the cover plug is in the T-shape, and is matched with a symmetry of the U-shaped drainage ditch. 
     
     
         4 . The road dust collection and drainage canal according to  claim 1 , wherein 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.
