米。結(jié)合實(shí)際情況，根據(jù)建筑物的性質(zhì)，用途，和室內(nèi)設(shè)有完善的給水排水衛(wèi)生設(shè)備，具體的給排水系統(tǒng)設(shè)計(jì)如下 ，屬一類(lèi)高層建筑住宅，耐火等級(jí)為一級(jí)，使用年限為 50 年。結(jié)合實(shí)際情況，根據(jù)建筑物的性質(zhì)，用途，和室內(nèi)設(shè)有完善的給水排水衛(wèi)生設(shè)備，具體的給水排水系統(tǒng)設(shè)計(jì)如下： 給水系統(tǒng)： 本建筑地下室有生活泵房，建筑供水采用高、中、低三個(gè)分 區(qū) ，地下室至七層為低區(qū)由市政管網(wǎng)供水，八層至十九層為中區(qū)，二十 層至三十層為高區(qū)，中、高區(qū)采用變頻調(diào)速水泵供水。從不同的方向引入。 排水系統(tǒng)： 設(shè)計(jì)中 采用污廢水 分 流排放體制，設(shè)專(zhuān)用通氣管，一層單獨(dú)排水。地下室內(nèi)，泵房前共設(shè)有三個(gè)集水坑和廢水提升裝置。在屋頂水箱間內(nèi)設(shè)實(shí)驗(yàn)用消火栓裝置，消火栓給水管網(wǎng)呈環(huán)狀布置，各消火栓箱內(nèi)設(shè)消防水泵啟動(dòng)電鈕 ，能直接啟動(dòng)消防泵；室外設(shè)地上式水泵結(jié)合器，保證消防安全可靠。 各系統(tǒng)中的立管設(shè)在管井內(nèi)或沿墻敷設(shè)，水平管根據(jù)各系統(tǒng)的特點(diǎn)明敷或暗敷。 關(guān)鍵詞： 給水排水系統(tǒng)設(shè)計(jì) ；消防系統(tǒng) 8 Abstract This building is the
