The automatic sprinkler system choose wet automatic sprinkler system. Determine its belong to the dangerous level of Ⅱ level risk level. This design USES the square nozzle arrangement, the most unfavorable point area of nozzle number is 15, the number of branch pipe work area for four. Indoor spraying water consumption of 45.18 L/s, the lift of pump is 76 m, flow rate Q = 45.18 L/s. Reason to choose the pump type for XBD10 / dl x5, 40-150 head 90 m and speed 1480 r/min, the efficiency of 76%, 55 kw power, NPSH 3.5 m. Choose two groups of the model pump, in one case, three water pump adapter.
Centralized automatic fire alarm system alarm system, determine its level of protection for object, selects the ionization smoke detector. Number of underground detector for 44, underground detector on the second floor of 51 number. The installation of the detector spacing for a = 10 m, b = 6 m.
This design will be underground layer and underground layer respectively as two levels fire zone. Each layer has two rooms and stairwells before smoke, as two smoke partitions separately, and the rest is pided into two smoke partitions, underground layer is pided into: 57.4 m2, 56 m2, 1490 m2, 1493.4 m2, underground layer is pided into: 53.3 m2, 22.1 m2, 1780 m2, 1784 m2. Choose HTFC smoke partitions - I - NO40 fire ventilation cabinet low noise centrifugal fan, a flow: after 82290 m/h, 890 pa, total pressure speed 580 r/min, motor: Y280S - 6, 55 kw power.
Key words: underground building；fire protection design；fire hydrant system；automatic sprinkler system； automatic fire alarm system
