【正文】 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.
