آنالیز ریسک آتش سوزی و پیشگیری از کریدور خط لوله جامع شهری

More and more comprehensive pipeline corridors are built in the urban cities to avoid the inconvenience effects of traffic jams to people's daily lives that pipelines laying caused and raise the quantity of pipeline management. While, the fire risk degree of comprehensive pipeline corridor is pretty high. This article analyses the fire risk type and characteristics in comprehensive pipeline corridor and discuss some fire safety prevention methods to reduce the loss that fire causes, such as fire partition design, structure material replace, automatic fire detective and extinguish system. High expansion foam system is suggested to be used in the comprehensive pipeline corridor for its low water use and high fire extinguish effect. The water use amount of high expansion foam system and normal water sprinkle system are compared. This advantage of high expansion system also means that the post-disaster recovery efforts are much less than that of normal water sprinkle system.
