【正文】 ent and the main factors of economic construction. So meet whole water use, at the same time saving water is also very important. In the options, select the best scheme requirement is reliable operation, investment saving, saving energy and water, no pollution, maintenance management convenient, long using life, etc. This design water using zoning watersupply modes, lower water supply is by direct municipal pipeline, high area adopt single set pump watersupply and water box modes, building interior drainage used separate system. Firefighting system used bined way of fire hydrant and automatic sprinkler system. Keywords: water supply and drainage hydrant automatic sprinkler III 目 錄 目錄 1 緒論

在選擇方案時，選擇最佳方案的要求是運(yùn)行可靠、投資省、節(jié)水節(jié)能、無污染、維護(hù)管理方便、使用時間長等。尤其是我國現(xiàn)在水資源缺乏，全國大部分的城市水資源缺乏，這已成為制約我國城市發(fā)展和經(jīng)濟(jì)建設(shè)的主要因素。 I 不是終稿可以參考！ 設(shè) 計 概 況 本設(shè)計是 十六 層 綜合 樓 的 給排水及消防設(shè)計。本設(shè)計主要包括：室內(nèi)給水系統(tǒng)設(shè)計、室內(nèi)排水系統(tǒng)設(shè)計、室內(nèi)消 防 系統(tǒng)設(shè)計。所以在滿足樓房整體用水的同時，水資源的節(jié)約也是非常重要的。本設(shè)計給水采用分區(qū)給水方式，其中低區(qū)由市政管網(wǎng)直接供水，高區(qū)為 設(shè)水泵 水箱 的給水方式，建筑內(nèi)部生活污廢水采用 分 流制排出，室內(nèi)的消防設(shè)計采用消火栓和自噴系統(tǒng)。
