Hydrant system design mainly includes the design of the outdoor hydrant and indoor hydrant system. Determining the quantity of outdoor fire hydrant, for indoor fire hydrant system, selection of caliber hydrant is 65mm, the water gun nozzle is 19mm, diameter is 65m, and length of rubber lined hose is 25m. The hydraulic calculation includes water column, fire protection, hydrant water gun nozzle radius, pressure, water jet flow resistance loss, hydrant mouth required water pressure, water tank .etc.
Selection of Automatic sprinkler system is wet type automatic water spraying fire extinguishing system. According to the standard, it belongs to the risk level of class I. The
design of each room is rectangular nozzle layout. In each room according to its length, width, the nozzle number, the nozzle location to determine the layout of its pipeline.
Automatic fire alarm and linkage control technology is a comprehensive technology of fire protection, which is a modern automatic fire fighting technology and an important component of the emerging technology subject. Design of automatic fire alarm system is an important aspect in the fire protection design of building. It relates to the automatic fire alarm system type selection, fire detection method, fire detector selection, system design, fire equipment and fire linkage control of distribution system and other aspects. The selection of smoke fire detectors is according to the mall building characteristics, and according to the installation spacing limit curve chart determine the distance between the probe, thereby determine the layout principle.
This design mainly involves the standard" code for fire protection design of buildings" GB50016-2014, for design of automatic fire alarm system," GB50116-2013" code for design of sprinkler systems" GB50084-2001," code for fire protection design of civil air defiance works". Main references of The design includes" building fire protection design handbook"," automatic water spraying fire extinguishing system design manual", building fire protection technology" and other books, and a large number of books in the Library Journal, many fire engineering design data, a large amount of information and knowledge collected from web they finally making completion of the high-rise arcade building fire protection design.
