【正文】 ty design. The distribution room and the garage are in the same layer, and the distribution room has the particularity of electrical fire, so it is necessary to design a separate fire design. The design is aimed at doing a relatively overall fire protection design for an underground garage, according to the unique structure of the underground garage, the special development laws of fire, and the successfully designed experiences of the underground garage in home and abroad and all the relevant fire control laws and regulations. This design involves four aspects: design for fire protection of construction, hydrant system, sprinkler system and design for fire protection of distribution room. The design’s purpose is through a prehensive fire protection design, to improve the success rate of rescuing early fire of the underground garage, decrease fire hazard and the damage caused by fire in the underground garage for ensuring the security of life and property.
