Embodiment 1
[0032] See attached figure 1, a prefabricated concrete unit body of a road rainwater guide, comprising a first structure 1 and a second structure 2; the first structure and the second structure are integrated; the upper surface of the first structure is a triangular inclined surface; the second structure The upper surface of the upper surface is a triangular inclined surface; the lowest point of the inclined surface of the first structure coincides with the lowest point of the inclined surface of the second structure; the long side 3 of the upper surface triangular structure of the first structure and the upper surface of the second structure The long sides of the triangular structure coincide; the length, width and thickness of the first structure are respectively consistent with the length, width and thickness of the second structure, wherein figure 1 A is the unmarked parameter map, figure 1 B is the labeled parameter map.
[0033] The above-mentioned inclined surface is ...
Embodiment 2
[0037] See attached figure 2 , a road rainwater guide prefabricated concrete, including a plurality of road rainwater guide prefabricated concrete units 4 integrally formed and arranged in sequence; the road rainwater guide prefabricated concrete unit includes a first structure 1 and a second structure 2; The first structure and the second structure are integral structures; the upper surface of the first structure is a triangular inclined surface; the upper surface of the second structure is a triangular inclined surface; the lowest point of the inclined surface of the first structure and the inclined surface of the second structure The lowest point coincides; the long side of the triangular structure on the upper surface of the first structure coincides with the long side of the triangular structure on the upper surface of the second structure; the length, width and thickness of the first structure are respectively the same as the length and width of the second structure , t...
Embodiment 3
[0041] See attached image 3 , a sidewalk rainwater guide, comprising prefabricated concrete 5 for the road rainwater guide and drainage cast iron grate 6; the above precast concrete for the road rainwater guide is the prefabricated concrete for the road rainwater guide in Embodiment 2, which is applied to the pavement near the sidewalk. The overall length of the prefabricated concrete at the road rainwater guide is 500mm, its width is 300mm, and its thickness is 50mm. For units with slopes at the same level, design corresponding drainage slopes in the radial and lateral directions of the road to conduct road rainwater diversion, and then effectively collect and discharge road rainwater within a certain range. image 3 In , the arrow indicates the rainwater flow direction, and the dotted line indicates that the road rainwater guide is prefabricated concrete embedded in the road surface.
[0042] The prefabricated concrete unit body of each level is inclined downward in the dr...
