Determine the use of the outdoor fire cock 4 the ground type outdoor fire hydrant, chuanmouth two 100 mm and 65 mm diameter; Indoor fire hydrant with 9 mm nozzle lining withglue and 65 mm and 65 mm hydrant faucet, pipe layout for the ring. Choose effective volumedetermined by hydraulic calculation for 18 m3 of water tank and effective volume of 676.728m3two independent use of fire pool and a XBD5/150-250 type of fire pump.By determining the fire danger rating for the dangerous level grade I, using wet automaticsprinkler system. So the network USES annular pipe network, using the central terminal waterintake. Through calculation of the data to calculate and determine the area of nozzle number is15, chooses two XBD4/15-80 type of fire pump.According to the actual circumstance of the building regulations and comprehensiveconsideration make sure mechanical smoke exhaust and smoke exhaust way choose naturalsmoke exhaust. By calculating exhaust quantity to determine the exhaust mouth size is 2300mm * 2000 mm, the size of the duct to 2500 mm x 4000 mm. Choose model for FBCDZ -12-32 of the fan.By determining object of protection for the level. Determine the alarm system controlcenter. Through the use of all kinds of detector range choose to smoke detector. Through thesmoke detector radius and protect area of number of detector to determine the detection area is75, 51 on the second floor, a layer of three 54 and four layers of 47.
Key words: multi-storey building; The bus station. Fire protection design; Safety evacuation;Fire hydrant system. The automatic sprinkler system
