AI Technical Summary
In existing technologies, the inadequate removal of sediment from rainwater inlets leads to a decrease in road drainage capacity, causing problems such as road flooding, traffic disruptions, and environmental pollution.
Design a curbstone filtration and drainage device, including a curbstone, a filter frame and a filter screen. The filter screen inside the filter frame allows for double filtration through the drainage holes on the curbstone, filtering out sediments larger than 10mm for easy cleaning. The filter screen is made of double-layer galvanized steel wire mesh, and the frame is made of cast iron.
It effectively filters out sediment from rainwater, reduces maintenance costs, maintains road drainage capacity, prevents sediment from hardening, simplifies the cleaning process, and reduces labor and equipment costs.
