The basement is used for equipment with a height of in which from the first floor to the third floor is shopping malls, 4th to17th floors is hotel rooms of meters heights。 18th to 20th floors is used for apartmentstyle office. This design includes the water supply system design, the drainage system design, the hotwater system design, the hydrant water supply system design and the sprinkler system design. Water supply systems: the water supply model of this building is zoned water supply. There is no water apparatus in basement where do not need water supply. In this building, 1st~3rd floor is lower zone, which is downfeed mode directly supplied by the municipal water supply work。 4th~12th floor is the central zone which is downfeed mode supplied by frequency conversion governor pump。 13th~20th floor is high zone which is uplink and down watersupply mode supplied by water pumps and roof tanks. Drainage system: the drainage system of 4th20th floor is separate mode for feces wastewater and other wastewater, including three standpipes and stack vent. The drainage system of 1st3rd floor is bined system which is drained to the outside drainage system. Hot water system: This building uses a centralized hotwater supply system which consistent with water supply systems. 4th12th floor is central zone and 13th20th floor is high zone. As the points of distribution in 1st3rd floor are less, there is not a hot water supply system there. Hotwater system in each zone is independent, using volume mode water heaters and concentrated layer equipment installed in the basement of the building, in which the main pipe cycle use pump to circling. Hydrant water supply systems: The building height is over 50 meters which is the first class of highrise buildings, in which indoor hydrant system is separated from domestic water supply system. The hydrant water supply system hasn’t been zoned. The entire system is a circle mode with 3 sets of water pump adapters. Sprinkler system: Since the risk level of the building is first class dangerous level, the sprinkler system is wet auto sprinkler system which is supplied from the pumps in basement and roof water tanks. There are 3 sets of alarm valve group and 2 sets of pump adapters. Behind the alarm valve group, there is a water flow indicator at the initial section of water supply submain pipe.
