Description

Rainwater drainage system and implementation method thereof Technical Field The embodiment of the application relates to the technical field of municipal engineering and road drainage, in particular to a rainwater drainage system and an implementation method thereof. Background In modern urban construction, the road drainage system is a "blood vessel" that ensures the safe operation of the city. The traditional roadside gully commonly called as a rainwater grate, usually adopts cast iron or concrete precast block structure, and has a plurality of defects: first, the clogging problem is serious. The traditional inlet for stom water lug connection drain pipe, debris such as silt, fallen leaves, plastic bag on the road surface are very easy to wash into along with the rainwater, and direct jam drain pipe or deposit at the ditch bottom leads to the drainage unsmooth. Whenever there is a storm, urban inland inundation frequently occurs, which is largely due to the failure of the gully. Second, dredging maintenance is difficult. The traditional gully has compact structure, once blocked, the heavy cast iron cover needs to be manually uncovered for cleaning, the operation environment is bad, and the efficiency is low. Because silt and pipe bottom mix, the desilting often is not thorough, needs frequent repeated operation, has increased huge municipal maintenance cost. Third, noise is easily generated. The traditional cast iron grate and the exposed gaps are easy to generate driving noise, and bang sounds generated by the wheel rolling grate. Today advocating the aesthetic of "city furniture" and the idea of sponge city, traditional gullies have failed to meet the requirements of high quality city landscapes. Fourth, the structure is single. Most of the existing gullies only consider drainage function, lack of filtering and purifying functions to initial rainwater, and cause road surface pollutants carried by initial rainwater to directly drain into natural water, so that non-point source pollution is caused.
