Automobile Hub Station Fire Protection DesignDesign general description: the object of the fire control design for car hub station, xx stationbase is located in the city the beijing-shanghai high-speed railway station square south, ma onshan road and jade road intersection. Total land area of 38062.9 m2, with a total constructionarea of 34147.30 m2, construction area of 33576.66 m2 on the ground, underground constructionarea of 570.64 m2.Design the main contents include: (1) building classification and fire resistance rating. (2)the construction general layout and fire prevention design. (3) construction safety evacuationdesign and calculation. (4) the choice of construction interior decoration materials that (5)calculation and indoor and outdoor fire hydrant fire system. 6. Calculation and automaticsprinkler system. All landowners calculation and fire extinguisher configuration. End upbuilding smoke exhaust design, calculation and illustration. Pet-name ruby automatic fire alarmsystem design and illustration.This design objects for the multilayer civil building, fire resistance rating for level 2.Design objects and the surrounding fire separation between other buildings conform to therelevant provisions, terminal room set up around the ring fire lane.Each layer as a fire partition, atrium, stairwells and wind well for independent fire zone.To determine the evacuation for the total number of 1038 people. Station house to a layerof safety evacuation door width: 85.8 m, 2 safety evacuation door width is: 7.5 m, three layerfor safe evacuation door width: 7.5 m, four levels of safety evacuation door width is: 4.5 m.Determine the number of evacuation exit a total of 73. Determination by enclosed stairwayapogee travel distance is the distance between two or three layers of the south corridor to theevacuation stair is 37.6 m.Analyzed the fire risk of interior decoration, and determine the decoration materials ofevery part and room combustion performance level and determine the specific use of decorationmaterials.The threat level to determine the fire extinguisher configuration places for serious dangerlevel. Fire type has A class A fire and E class fire danger, and choosing portable ammoniumphosphate dry powder fire extinguishers. Determined by the radius of the protection area of thecell and need 65 5 kg portable MF/ABC5 fire extinguisher. 汽车枢纽站消防设计+图纸:http://www.751com.cn/gongcheng/lunwen_41047.html
