AI Technical Summary

Technical Problem

The narrow cross-sections and limited space of roads in the old urban areas make it difficult to effectively expand existing rainwater collection and drainage facilities, resulting in slow drainage, road damage, serious traffic safety and environmental impacts, and making it difficult to achieve the source emission reduction goals of sponge city construction.

Method used

The system employs a prefabricated linear and sponge-type drainage system, including an egg-shaped drainage ditch and linear water collection and sponge-type drainage side ditches. Through modular design, continuous and gradually expanding water passages and sponge-type seepage holes, combined with a porous plate-like filter structure and rubber waterstop, it achieves efficient collection, infiltration and filtration of rainwater, improving structural stability and sealing.

Benefits of technology

It improves rainwater collection and drainage efficiency, reduces the risk of road flooding, lowers maintenance frequency and costs, achieves source emission reduction, and improves the traffic environment and the service life of road structural layers.
