The Design of Water Supply and Drainage Engineering of R & D Building of Zhen Jiang office building
Abstract
This engineering is a main house for the 17th floor high-rise office buildings, underground, 17, the ground layer, building a total height of 70.5 m, covers an area of 3018 m2, construction area of 24132.6 m2, with life water tank, fire pool and water pump room in the basement. There is a municipal water pipeline at 10m in the north of the building, and the above ground level is -1.5m, the lowest pressure is 25m water head. The sewage drains into the septic tank.
This design includes indoor water cold water supply system, indoor life drainage system, indoor fire hydrant system and indoor automatic sprinkler system. Among them, the indoor cold water supply system is divided into three zones, one to four floor just to municipal low, directly by the municipal pipe network supply and five to ten for the pressure area on the second floor, from set in the basement of the central frequency conversion water supply equipment, water supply; The high zone above 13 and 13 floors is supplied by the high zone variable frequency water supply in the underground layer. The drainage system of indoor drainage is used to waste water and sewage.

According to the calculation, the fire hydrant water system is not partitioned. Fire water from the fire water system, which is set up in the lower level of the underground water system, and the water supply of the fire pump in the fire water system of the fire water system. Indoor fire hydrant fire water system design for annular pipe network, indoor set fire hydrant for each layer, and ensure that there were two full tree water at the same time to reach any part of the interior. According to the regulation, the building is a type 2 high-rise, indoor fire water use is 30L/s, and the fire duration is 2 hours. Early fire by roof water tank water supply, indoor fire hydrant fire water supply system, fire pump start by indoor fire hydrant fire water system of fire pump pressurized water supply. Fire danger rating according to the levels of dangerous Ⅰ above ground and basement levels according to the dangerous Ⅱ set up automatic sprinkler system, the technical specification for the building water supply and fire hydrant system, fire hydrant system and automatic sprinkler system of this project shall be set up regulated facilities, water levels in dangerous Ⅰ strength for 6 l/min. M, covers an area of 160 ㎡. System design flow 20.8 L/s, fire lasted for 1 hour, fire duration of fire duration of fire extinguishing required fire water was 578.88 cubic meters. Set 6 wet alarm valve series of aerial part five groups, each group of alarm valve control on the number of nozzle are less than 800, floors and the fire zone indicator set flow, early by roof water tank water supply, fire sprinkler system, fire pump start fire pump pressurized water supply by the automatic sprinkler system.
