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。给水系统采用分区供水，-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。给水横管采用PP-R塑料管，立管采用无缝钢管。排水系统采用污废水合流制。底层单独排水，合流排放，立管采用伸顶通气。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 Hohhots procuratorate building- eighteen floors Name Zhangfan Tutor Yinzhenyu Abstract This 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?.00.oThe 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? podiu ms’water supply is based on the outside network pressure,5?8 dlayers 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 sewage and wastewater combining system.The first floor drain separately and discharge in interflow,the risers use stretch top ventilation without special ventilation risers.The design of fire fighting system is composed of fire hydrant extinguishing system and automatic sprinkler system.Water supply is united by water pump and water tank to the fire hydrant system.The early ten minutes fire water supply is from the fire protection water tank,and the water of the fire protection water tank comes from the living water pump;aft
