4. The lower storage channel can form a rainwater storage capacity within the comprehensive management, enhance the waterlogging prevention of the corresponding area and promote the comprehensive utilization of rainwater, and become an organic part of the sponge city;

5. There are two ways of regulating and storing the water inlet device: overflow entry and active collection, which can be flexibly selected according to the setting of the urban rainwater system;

6. There are two discharge methods for the outlet pipeline of the lifting discharge device, one is to discharge to the upper high-level rainwater pipeline to realize the staggered peak of rainwater, and the other is to discharge to the external rainwater reuse facility for comprehensive utilization of rainwater. There are two discharge methods It can be flexibly selected according to the urban rainwater system settings.
