呼市检察院大楼给排水及消防设计—18 层 摘要 本工程为呼市检察院大楼，共 18 层，建筑总高度 68.4 米,属一类高层建筑。地下一层,地上 18 层，每层层高 3.8 米。一层室内地坪标高为±0.00。市政给水管网压力为 0.25MPa ，生活给水系统、排水系统均从建筑物北侧通过，给、排水标高分别为-2.2m，-1.6m。本次设计主要包括给水系统、排水系统、消防系统。给水系统采纳分区供水，-1—4 层为低区，利用市政管网直接供水，5—18 层为高区，利用变频泵加压供水。给水横管采纳 PP-R 塑料管，立管采纳无缝钢管。排水系统采纳污废水合流制。底层单独排水，合流排放，立管采纳伸顶通气。本设计的消防系统由消火栓灭火系统和自动喷水灭火系统组成，由水泵、水箱联合供水。火灾初期 10min 消防用水量由屋顶消防水箱供给，消防水箱的水源由生活水泵补给；10min 后的消防系统启动消防水泵，从消防水池抽水供消火栓以及喷头使用。[关键词]高层建筑 给水系统 排水系统 消防系统 Water supply and drainage and fire fighting design of Hohhot's procuratorate building- eighteen floorsName ZhangfanTutor YinzhenyuAbstractThis project is Hohhot’s procuratorate building ,a total of 18 storeys.It is 68.4 meters in height ,Secret 1 layer,18 layers on the ground,each is 3.8 meters high.Ground of the one layer of indoor level ground level is±0.00.The reliable water head to the waterpipe net of city for 0.25 Mpa.The drinking water system and drainage system are from the north through buildings ,To the elevation of- 2.2 m, respectively, drainage - 1.6 m. This design mainly includes the water supply system, drainage system,and fire fighting system.water supply system district the water supply.-1—4 podiums’water supply is based on the outside network pressure,5—18 layers are divided into a zone which use pressurizing water supply,and it uses pump to pressurize. Horizontal pipe of water supply choose The PP - R plastic pipe,and the riser adopts the seamless steel pipe.The drainage system use se...
