The utility model relates to the technical field of
road engineering construction, in particular to an
urban road rainwater drainage
system, which is characterized in that a curb is fixed on the edge of a road through
cement mortar, a well body is positioned in a green open space and is tightly attached to the curb, a well ring is fixed on the upper edge of the well body through
cement mortar, a cover groove is arranged at the top of the well ring, and a well cover is arranged in the cover groove. The cross sections of the well body and the well ring are rectangular structures, and the upper edge of the well body is higher than the
greening vacant ground; the outer side of the curb is an upstream face, the upstream face is designed to be an inwards-concave arc face, and the inner side of the curb is a vertical face. The vertical face is tightly attached to the well ring and the outer side wall, exposed out of the
greening open space ground, of the well body, and the upper edge of the well ring is higher than the upper edge of the curb. Drainage holes penetrating through the upstream face and the vertical face are formed in the curb at intervals; a first water inlet groove is formed in the side, attached to the vertical face, of the well body and corresponds to the drainage hole. And a grate does not need to be arranged on the
road surface, so that the integrality and the completeness of the road are improved, and the appearance quality of the road is also greatly improved.
