【正文】 reliable. Basement, a layer of shops located closetype automatic spray systems. Risers in each system within the well established or laid along the wall, horizontal tube according to the characteristics of the system provides inadequate or concealed. Principles of the design economy, environmental protection, energy saving, by drawing 華東交通大學(xué)理工學(xué)院畢業(yè)設(shè)計(jì) 9 lessons from previous design methods and experiences, using reasonable technical measures, give the design of various systems has achieved very good results. Key words: Design of water supply and drainage systems。 This building possesses for water draining water presses the highrise construction to request for draining water to carry on the design. Unifies the actual situation, according to the building nature, the use, is equipped with the consummation with the room in for the water draining water sanitary equipment, concrete gives the drainage system design to be as follows: Water supply system: This basement pump room, building water supply with high, medium and low three divisions, the basement area by municipal pipe work to 7 storeys to low water supply, 8 to 19 stories for the Central, 20 to32 storeys high, high adoption of variable frequency speed governing pump in water supply. Since more than ten fire hydrants, needed two service pipe. Fed from different directions. Ensure the safety of water supply, and to save energy. Drainage systems: Design of sewage wastewater emission system of triage, set aside special ventilation tube, a separate drainage layer. Pipe PVCu pipe. In the basement, before the pump house which houses three sump pit and waste water lifting device. Fire protection system: The buildings 39。 本設(shè)計(jì)以經(jīng)濟(jì)、環(huán)保、節(jié)能為原則，通過(guò)借鑒以前的設(shè)計(jì)方法和經(jīng)驗(yàn)，采用了合理的技術(shù)措施，使設(shè)計(jì)的各個(gè)系統(tǒng)達(dá)到了很好的使用效果。地下室、一層商店設(shè)閉式自動(dòng)噴淋系統(tǒng)。 消防系統(tǒng)： 該建筑防火等級(jí)屬于中危險(xiǎn)級(jí)Ⅰ級(jí)，設(shè)計(jì)內(nèi)容包括消火栓系統(tǒng)和自動(dòng)噴淋系統(tǒng)。管材采用了具有 PVCU管。保障了供水安全，又節(jié)約能耗。由于消火栓超過(guò)十個(gè)，需設(shè)兩條引入管。本建筑物所有給水排水均按高層建筑給水排水要求進(jìn)行設(shè)計(jì)。 本建筑物所有給水排水均按高層建筑給排水要求進(jìn)行設(shè)計(jì)。 （保密的畢業(yè)設(shè)計(jì)（論文）在解密后適用本授權(quán)書） 畢業(yè)設(shè)計(jì)（論文）作者簽名： 指導(dǎo)教師簽名： 簽字日期： 年 月 日 簽字日期： 年 月 日 2 華東交通大學(xué)理工學(xué)院畢業(yè)設(shè)計(jì) 3 目 錄 摘 要 ............................................................................................................................................. 7 ABSTRACT ......................................................................................................................................... 8 第一部分 設(shè)計(jì)說(shuō)明書 ............................................................................................................... 10 1 設(shè)計(jì)任務(wù)書及設(shè)計(jì)資料 ........................................................................................................... 10 1． 1 畢業(yè)設(shè)計(jì)題目 .................................................................................................................. 10 1． 2 工程概況 .......................................................................................................................... 10 1． 3 工程設(shè)計(jì)內(nèi)容及要求 ...................................................................................................... 10 1． 3． 1 設(shè)計(jì)內(nèi)容 .............................................................................................................. 10 1． 3． 2 設(shè)計(jì)要求 .............................................................................................................. 10 2 設(shè)計(jì)方案的比較和確定 ........................................................................................................... 11 2． 1 生活給水系統(tǒng)的方案設(shè)計(jì) .............................................................................................. 11 設(shè)計(jì)依據(jù) ....................................................................................................................... 11 生活給水系統(tǒng)所需水壓力 H（估算） ....................................................................... 12 豎向分區(qū)的 劃分 ........................................................................................................... 13 給水系統(tǒng)方案的比較及確定 ....................................................................................... 13 消火栓給水系統(tǒng)的方案設(shè)計(jì) ............................................................................................. 17 設(shè)計(jì)依據(jù) ....................................................................................................................... 17 室外消火栓給水系統(tǒng) ................................................................................................... 19 室內(nèi)消火栓給水系統(tǒng) ................................................................................................... 19 室內(nèi)消火栓給水系統(tǒng)的豎向分區(qū) ............................................................................... 21 消火栓供水方案的確定 ............................................................................................... 21 系統(tǒng)組成 ....................................................................................................................... 22 自動(dòng)噴淋給水系統(tǒng)的方案設(shè)計(jì) ......................................................................................... 22 設(shè)計(jì)依據(jù) ....................................................................................................................... 22 設(shè)計(jì)方案 ....................................................................................................................... 24 噴頭選擇 ....................................................................................................................... 25 排水系統(tǒng)的方案設(shè)計(jì) ......................................................................................................... 26 設(shè)計(jì)依據(jù) ....................................................................................................................... 26 建筑物外排水系統(tǒng) ....................................................................................................... 29 4 室內(nèi)排水體制的選擇 ................................................................................................... 29 ...............................................
