Bioretention Cell - Hydrophilic Rock Wool - Water Storage Module
This modular solution addresses the insufficient storage capacity of bioretention facilities. The modules are embedded within the facilities, functioning as invisible "water tanks" that store water during rainfall and slowly release it through capillary action during drought, enabling cross-temporal rainwater utilization, solving the problems of water storage limitation and water stress on plants during dry periods.
Modular Assembly: Standard dimensions allow easy transport and on-site configuration, flexible enough to suit various irregular shapes, significantly reducing design and procurement lead times.
Strong Water Regulation Capacity: Effective void ratio ≥ 85%, same-volume water storage is more than five times that of traditional soil, greatly improving annual runoff capture rates and helping achieve sponge city goals.
Low Maintenance: Stable structure resists clogging, eliminating the need for regular cleaning or replacement. Compared to infiltration wells or pipes requiring frequent unclogging, life-cycle maintenance costs can be reduced by 60%.
Plant Growing Support: Fiber structure allowing roots to grow freely, ensuring healthy vegetation, improved aesthetics, and enhanced ecological function.
Excellent Durability: Inorganic material resistant to freeze-thaw cycles and acid/alkali environments, with an underground service life 15-30 years. One-time investment without concerns about material aging and secondary construction.
