摘要:本次設(shè)計題目為蘇州市五亭商務(wù)廣場寫字樓建筑給水排水工程設(shè)計，該建筑屬于綜合性大樓，為中危險Ⅰ級建筑物。 具體設(shè)計項目為：室內(nèi)給水工程，室內(nèi)排水工程，室內(nèi)消防工程（包括消火栓系統(tǒng)和自動噴淋系統(tǒng)），室內(nèi)熱水工程，共5部分。 生活給水系統(tǒng)分為高區(qū)和低區(qū)。低區(qū)1～4層由市政管網(wǎng)直接供水，采用下行上給式供水方式；高區(qū)5～16層由水箱、水泵聯(lián)合供水采用上行下給式供水方式，水箱容積為3.9,有效容積為3.6，水泵選用IS80-50-250A。一層設(shè)備房設(shè)有貯水池和水泵房。屋頂設(shè)高位水箱，生活水箱與消防水箱分設(shè)。 排水采用合流制，每根立管在16層頂采用伸頂通氣，每根排水管均設(shè)置DN100的通氣立管。本系統(tǒng)共設(shè)置17根排水立管和4根國際01S302.87型DN200雨水斗。污廢水均排入到室外化糞池，化糞池為40。 消火栓系統(tǒng)不分區(qū)，采用水箱和水泵聯(lián)合供水的臨時高壓給水系統(tǒng)。每個消火栓箱內(nèi)設(shè)消防泵啟動按鈕，消防時可直接啟動水泵。消防水泵選用XA65/26A型，消防水箱容積為18，貯存有10分鐘的消防水量。火災(zāi)延續(xù)時間以2小時計。該系統(tǒng)共設(shè)置11根立管，每根立管管徑均為DN100。 采用濕式自動噴水滅火系統(tǒng)。該建筑物分為三個區(qū)，每個區(qū)設(shè)一根立管，共三根立管。每根立管均連接一個報警閥，濕式報警閥設(shè)置于一層設(shè)備房內(nèi),水力警鈴裝在報警閥附近?；馂?zāi)延續(xù)時間以1小時計。該噴頭系統(tǒng)整體采用矩形布置，A、B類辦公室采用普通型和邊墻型噴頭聯(lián)合設(shè)置。 室內(nèi)熱水采用集中式熱水供應(yīng)方式，為了保證熱水和給水的壓力平衡，熱水與冷水的分區(qū)和管道布置均一致，分高低兩個區(qū)，低區(qū)1～4層采用下行上給式供水方式；高區(qū)5～16層采用上行下給式供水方式，因高區(qū)連接水加熱器導(dǎo)致水損較大，故在高位水箱出口處設(shè)置氣壓罐進(jìn)行加壓。本設(shè)計均采用熱水循環(huán)系統(tǒng)。 設(shè)計過程進(jìn)行了個系統(tǒng)方案的確定、平面布置和計算，以及各種設(shè)備的選型。最后用CAD繪制了各個系統(tǒng)平面圖和原理圖?！?/p> 關(guān)鍵詞 高層建筑；給水系統(tǒng)；排水系統(tǒng)；熱水系統(tǒng)；消防系統(tǒng)
Abstract:This design topic for the drainage engineering building water supply design office of Suzhou city after the Plaza, the building belongs to the comprehensive building, for the risk grade I buildings. The specific design project: indoor water supply engineering, indoor drainage engineering, engineering (including indoor fire hydrant system and automatic sprinkler system), indoor hot water project, a total of 5 parts. Life water supply system is divided into high and low area. Low area 1 ~ 4 layer by the municipal water supply pipe network directly, using downfeed type water supply mode; high 5 ~ 16 layer consists of a water tank, water pump and water use upstream to water supply, water volume of 3.9 cubic meters, the effective volume of 3.6 cubic meters, water pump selection IS80-50-250A. A layer of equipment room with storage tank and pump house. Roof set high water tank, water tank and water tank is divided into life. The use of drainage confluence, each vertical pipe in the 16 layer of the top of the ventilating, vertical pipe ventilation were set DN100 of each drainage pipe. The system set up a total of 17 drainage pipes and 4 international 01S302.87 DN200 rain water bucket. Waste water is discharged into the outdoor septic tank, septic tank of 40 cubic meters. Fire hydrant system does not partition, use of temporary high pressure water supply system water tank and pump water supply system. Each hydrant box set fire pump start button, can directly start the fire pump. The fire pump selection of XA65/26A type, fire water tank volume of 18 cubic meters, 10 minutes of fire water storage. The fire lasted for 2 hours. The system comprises of 11 vertical pipes, each root diameter vertical tubes are DN100. Using wet automatic fire-extinguishing sprinkler system. The building is divided into three zones, each zone of a vertical tube, a total of three riser. Each vertical pipe is connected with an alarm valve, wet alarm valve is arranged on a layer of equipment room, hydraulic alarm installed in the alarm valve near. The fire lasted for 1 hours. The overall use of rectangular arrangement of the sprinkler system, A, B office using ordinary type and wall type nozzle joint set. Indoor hot water with hot water supply mode of centralized, in order to guarantee that the pressure balance water and water supply, partition and piping hot and cold are consistent, level two, 1 to 4 layers of low area using downfeed type water supply mode; high 5 ~ 16 layer using the uplink to water, because of high connection the water heater caused great loss of water, the pressure tank is arranged in the water tank outlet pressure. This design uses the hot water circulation system. The design process of a system plan, layout and calculation, selection and various equipment. Finally using CAD draw every system of plane diagram and schematic diagram. Keywords high-rise building water supply system drainage system hot water system fire protection system |
