ABSTRACT
This design is a comprehensive water supply and drainage for the Raffles City A1 section of
Chongqing and some towers. District Raffles a 1 bid section. It mainly includes eight parts: water
supply system, drainage system, pipeline pressure, valve material selection, BIM deepening,
pipeline system, reuse system, construction scheme and so on. The water is supplied by the
municipal water supply network. The water supply main of the project is to introduce a DN300
water supply main from the East and west side of the municipal water supply pipeline. The
basement non-hotel area function room uses the municipal water pressure direct water supply.
Water for waterscape engine room and outdoor landscape is provided by reclaimed water system.
The Siphon system is adopted in the design of the Skirt Building Rainwater, and the gravity flow
system is adopted in the area that can not satisfy the siphon condition. Rainwater is diverted to the
Yangtze River and the Jialing River River by gravity flow and discharged into the existing
municipal drainage channels. The swimming pool water treatment circulation system adopts the
counter-current circulation mode recommended by FINA. Due to the requirement of the external
facade and the overfall of the roof, the drainage capacity of the storm water bucket and storm water
standpipe system is designed to meet the 50-year recurrence period. At the beginning of the design,
I made various options for the scheme. Bim was deepened, then selected materials and finalized,
and compared with the construction scheme, the pipe network diagram of the water supply and
drainage system is drawn with CAD drawing software, and the loop principle of the skirt building
and part of the tower building is explained according to the system diagram, to increase the
efficiency of the original cost and improve the overall aesthetic.
