1、呼市檢察院大樓給排水及消防設(shè)計(jì)—18層摘要本工程為呼市檢察院大樓,共18層,建筑總高度68.4米,屬一類高層建筑。地下一層,地上18層,每層層高3.8米。一層室內(nèi)地坪標(biāo)高為±0.00。市政給水管網(wǎng)壓力為0.25MPa,生活給水系統(tǒng)、排水系統(tǒng)均從建筑物北側(cè)通過,給、排水標(biāo)高分別為-2.2m,-1.6m。本次設(shè)計(jì)主要包括給水系統(tǒng)、排水系統(tǒng)、消防系統(tǒng)。給水系統(tǒng)采用分區(qū)供水,-1—4層為低區(qū),利用市政管網(wǎng)直接供水,5—18層為高區(qū),利用變頻泵加壓供水。給水橫管采用PP-R塑料管,立管采用無縫鋼管。排水系統(tǒng)采用污廢水合流制。底層單獨(dú)排水,合流排放,
2、立管采用伸頂通氣。本設(shè)計(jì)的消防系統(tǒng)由消火栓滅火系統(tǒng)和自動(dòng)噴水滅火系統(tǒng)組成,由水泵、水箱聯(lián)合供水。火災(zāi)初期10min消防用水量由屋頂消防水箱供給,消防水箱的水源由生活水泵補(bǔ)給;10min后的消防系統(tǒng)啟動(dòng)消防水泵,從消防水池抽水供消火栓以及噴頭使用。[關(guān)鍵詞]高層建筑給水系統(tǒng)排水系統(tǒng)消防系統(tǒng)IWatersupplyanddrainageandfirefightingdesignofHohhot'sprocuratoratebuilding-eighteenfloorsNameZhangfanTutorYinzhenyuAbstractThis
