远洋新干线消防设计

I设计题目：远洋新干线消防设计专业：消防工程毕业生：杨迪（签名）指导教师：马砺（签名）王伟峰（签名）摘要设计建筑为一类高层商住楼，地下一层，地上二十八层，室外地坪标高为-2.5m，主体建筑高度82m，1层面积1490m2，2层和高层主体面积1076.5m2。地下车库面积1372m2。该建筑的防火等级属于中危Ⅰ级，主要火灾类型为A类，其次为电气火灾。本设计主要由消火栓系统、喷淋系统、灭火器配置、防排烟系统、防火分区和安全疏散、火灾报警系统等组成。消防给水系统采用水箱水泵联合供水方式，室内消火栓用水量为43.09L/s，负一层至九层采用SNJ65型减压稳压消火栓，九层以上采用SN65型消火栓。室外设消火栓用水泵接合器4个，室外消火栓系统设计流量为30L/s，设两个地上式消火栓。自动喷水灭火系统设计喷水强度为6L/（min·m2），作用面积为162.2m2，作用面积内喷头数为29个，用水量为58.7L/s。可选用手提式磷酸铵盐型干粉灭火器,灭火级别为5A。配电室使用七氟丙烷（HFC—227ea）气体灭火系统。楼梯和电梯合用前室和地下一层设置防排烟系统。防烟楼梯间采用自然通风，合用前室使用正压送风系统。每层共有3个防火分区，以每单元为界。楼梯和安全出口符合高规规定标准。在负一到二层平面和住宅区合用前室设火灾报警系统。关键词：高层建筑消火栓自动喷水防排烟IISubject:Subject:Subject:Subject:FFFFireireireireprotectionprotectionprotectionprotectiondesigndesigndesigndesignofofofofYuanYangXinGanXianYuanYangXinGanXianYuanYangXinGanXianYuanYangXinGanXianProfessionalProfessionalProfessionalProfessional：：：：FireFireFireFireEngineeringEngineeringEngineeringEngineeringName:Name:Name:Name:YangYangYangYangDiDiDiDi（（（（signaturesignaturesignaturesignature））））________________________________________________Supervisor:Supervisor:Supervisor:Supervisor:MaMaMaMaLLLLiiii（（（（signaturesignaturesignaturesignature））））________________________________________________（（（（signaturesignaturesignaturesignature））））________________________________________________AbstractAbstractAbstractAbstractThebuildingisakindofhighrisebuildings,underground,on28thstorey,outdoorfloorelevationof-2.5m,themainbuildingheight82m,1floorareaof1490squaremeters,twolayerandupperbodyareaof1,076.5squaremeters.Undergroundgarageareaof1372squaremeters.Thebuilding'sfireratingisindangerⅠlevel.Setfireextinguishers,asthehigh-riseofficebuildingbelongingtothemainfiretypesClassA,followedbyanelectricalfire.thedesignincludeshydrantsystems,sprinklersystems,fireextinguishersconfiguration,smokecontrolsystems,firedistrictandsafeevacuation,firealarmsystemsandothercomponents.Firewatertankpumpsystemusingjointwatersupply,firehydrantwaterwas43.09L/s,anegativeonetoninehydrantusingSNJ65typevacuumregulator,nineaboveusingSN65typefirehydrant.Roomperipheralshydrantpumpadapter4withoutdoorfirehydrantsystemdesignflow30L/s,settwogroundfirehydrant.Automaticsprinklersystemdesignsprinklerstrength6L/(min•m),theroleofanareaof160squaremeters,theroleofanareainsidethenozzlenumberis29,waterconsumptionis58.7L/s.Optionalportableammoniumphosphatedrypowderfireextinguishers,firelevel5A.DistributionroomusingHeptafluoropropane(HFC-227ea)gasfireextinguishingsystem.Stairsandelevatorssharedroomandbasementsmokecontrolsystemsettings.Stairwellwithnaturalventilation,sharedroomwithpositivepressureairsupplysystem,amechanicalexhaustsystembasement.Therearethreeoneachfiredistrict,perunitforthesector.Stairsandsafetyregulatoryrequirementsexportsmeethighstandards.Inthenegativeonetothesecondfloorandresidentialsharedroomflatlocatedthefirealarmsystem.KeyKeyKeyKeywordswordswordswords：High-risebuildingFirehydrantwatersupplyTheautomaticsprinklersmokecontrolIII目录目录目录目录1111工程概况...........................................................................................................................11.1建筑概况.................................................................................................................11.2设计依据.................................................................................................................11.3设计内容................................................................................................................11.3.1设计计算书..................................................................................................11.3.2设计图纸......................................................................................................22222消火栓系统设计..............................................................................................................32.1设计步骤.................................................................................................................32.2设计参数.................................................................................................................32.3消防系统的选择.....................................................................................................42.4水枪充实水柱确定与消火栓保护半径的计算.....................................................42.4消火栓间距的计算.................................................................................................62.5高区管网消火栓水利的计算.................................................................................62.5.1水利的计算..................................................................................................62.5.2消防水泵的选型........................................................................................102.5.3高区各层消火栓栓口动水压力的计算....................................................102.6消防水箱的计算...................................................................................................112.6.1水箱水量的计算........................................................................................112.6.2消防水箱的设置高度............................................................
