AI Technical Summary
Due to the blockage of urban drainage pipe networks due to leaves, sand and gravel, plastic bags and other items, existing filter barrels are easily blocked, making it difficult to effectively filter out smaller sand and gravel and other garbage, making it difficult for rainwater to enter the rainwater well and causing pipeline blockage.
A system including sewage pipe network and rainwater pipe network was designed. A four-sided table-shaped filter barrel and a ball-shaped filter net were installed in the rainwater well. The filter barrel and filter net were distributed with large and small filter holes, combined with concrete cover plate and rainwater grate. Filter barrels and filters can intercept large amounts of garbage and sand and gravel to prevent clogging.
Effectively filter out large garbage such as plastic bags and leaves, filter out small garbage such as sand and gravel through filters to prevent blockage of urban drainage pipes and ensure the normal operation of rainwater wells.
