采用自动化供排水设计，并搭配成本较高的大功率的水汞，确保水喷淋的流速

It adopts automatic water supply and drainage design, and is matched with high-cost high-power water mercury to ensure the flow rate and uniformity of water spraying.

 automatic water supply and drainage design is adopted, combined with high-power water mercury with high cost to ensure the flow rate and uniformity of water spray.

Structurally, both the conventional roof rainwater collection and utilization system and the green roof rainwater collection and utilization system can be divided into rainwater collection, treatment and reuse systems, and the difference is that the latter rainwater collection system adds green roof. Green roof puts forward new requirements for building load-bearing and roof waterproofing, and needs to fully communicate with landscape architecture specialty. Automatic water supply and drainage design and high-power mercury water with high cost are adopted to ensure the flow rate and uniformity of water spray.
