Technical Field

The utility model relates to the technical field of urban drainage, in particular to a drainage structure based on a permeable pavement.

Background

As is known, the cause of urban flood is that the precipitation is too large, and the inflow of a certain area of the city is greater than the discharge, so that rainwater is deposited to a certain amount, and finally flood is formed. Through experience summary of multiple raining and flood forming, the main forming areas of the flood are as follows: low-lying and incomplete drainage facilities. A low-lying area is subject to not only precipitation in that area but also drainage from adjacent areas, which can easily cause flood damage if drainage facilities are lacking.
