of residential buildings 9~11#, 6~8# floor, are a class of commercial and residential buildings. The fire pool is set up on the top of 11#.
This project is a building of the 7#. With the drinking water system, sewage system, sewage system, drainage system, fire hydrant water supply system, automatic sprinkler fire extinguishing system.
Fire protection system: this project underground garage sets the life water tank and the water pump. The indoor fire hydrant system design flow for 40L/S. According to 2 hours fire duration calculation of water storage, outdoor fire hydrant system design flow 30L/S. According to 2 hours fire continued time calculation of water storage, the building about , is more than seven storey residential buildings, indoor hydrant water supply system is set up in the building and without partition. Water tank by the life of the pump water, storage 10min fire water, fire early by the water tank fire, fire pump started by the fire pump water supply fire. In addition, it should set the test and inspection of the fire hydrant on the flat roof. Automatic sprinkler system design flow 40L/S. According to one hour fire duration calculated water. According to the specification of the building for senior housing, for a class of construction belongs to the dangerous level, so the design spray intensity - square meters 106L/min. Area of effect for 160 square meters, nozzle pressure is . Pool fire and fire pump set in 7# floor, the ground floor of a layer of, according to the actual set corresponding high fire water ring network and pressure reducing valve after the low area fire water ring network, supply the corresponding monomer and underground garage fire water supply system.
Water supply system: the water supply system of this project is about , which only meets the requirement of one layer of water. So consider tw
