【正文】 《給水排水管道系統(tǒng)》 設(shè)計(jì)說(shuō)明 系 別: 環(huán)境與市政工程學(xué)院 專(zhuān) 業(yè) : 給水排水 工程專(zhuān)業(yè) 姓 名: 學(xué) 號(hào): 0130 指導(dǎo)教師: 譚水成 實(shí)習(xí)時(shí)間: 河南城建學(xué)院 2021 年 12 月 25 日 杭州市給水排水管網(wǎng)設(shè)計(jì) 2 前 言 本次給排水管道的實(shí)習(xí)課程是對(duì)杭州市給排水管網(wǎng)進(jìn)行設(shè)計(jì),實(shí)習(xí)時(shí)間為兩周,結(jié)合實(shí)際設(shè)計(jì),使同學(xué)們對(duì)管道設(shè)計(jì)的知識(shí)和注意事項(xiàng)有更深刻的理解。 隨 著城市化進(jìn)程的加快,給水排水工程已經(jīng)發(fā)展成為城市建設(shè)和工業(yè)生產(chǎn)的重要基礎(chǔ)設(shè)施,成為人類(lèi)健康安全和工農(nóng)業(yè)科技與生產(chǎn)發(fā)展的基礎(chǔ)保障。給水排水系統(tǒng)是為人們生活、生產(chǎn)、市政和消防提供用水和廢水排除設(shè)施的總稱。給水排水工程由給水工程和排水工程兩大部分組成。本設(shè)計(jì)針對(duì)這兩部分對(duì) 杭州 市給水排水管道進(jìn)行設(shè)計(jì)。 設(shè)計(jì)過(guò)程中,先大致了解 杭州 市地形分布后,決定通過(guò)分區(qū)供水滿足整個(gè)城市的用水需求。定線,給誰(shuí)水力計(jì)算,確定管徑,校核等等,把定下的管徑標(biāo)圖并整理報(bào)告??紤]城市初步規(guī)劃,以及資金投資問(wèn)題,采用完全分流制排水系統(tǒng)。生活污水 和工業(yè)廢水通過(guò)污水排水系統(tǒng)送至污水處理廠,經(jīng)處理后再排入水體。雨水是通過(guò)雨水排水系統(tǒng)直接排入水體。 課程設(shè)計(jì)讓我們結(jié)合所學(xué)知識(shí),運(yùn)用 CAD 制圖,畫(huà)出 杭州 市給水排水管道總平面分布圖,部分污水干管剖面圖,及給水等水壓線圖等,學(xué)會(huì)靈活運(yùn)用知識(shí)。 杭州市給水排水管網(wǎng)設(shè)計(jì) 3 Preface The water supply and drainage pipeline of practice course is on water supply and drainage pipe work in hangzhou city design, practice time for two weeks, bined with the actual design, make the students knowledge of pipeline design and matters needing attention to have a more profound understanding. With the speeding up of urbanization, water supply and drainage engineering has bee the important foundation of the urban construction and industrial production facilities, bee a human health safety and the basis of industrial and agricultural production and development of science and technology. Water supply and drainage system is for people39。s life and production, municipal and fire the floorboard of the ruled out water and wastewater facilities. Water supply and drainage engineering is posed of two most of the water supply and drainage engineering. This design for the two parts of hangzhou city water supply and drainage pipeline design. The design process, first a general idea of hangzhou topography distribution, decided to meet the demand of the whole city water supply by partition. Who alignment, hydraulic calculation, to determine the pipe diameter, check, etc., the set of pipe diameter plotting and finishing report. Considering the preliminary planning, as well as capital investment, adopt pletely separate system and drainage system. Life sewage and industrial wastewater by sent to the sewage treatment plants, sewage drainage system was treated and then discharged into water body. Rain water is directly discharged into water body by rainwater drainage system. Let39。s bine knowledge in course design, using the CAD drawing, draw the hangzhou city water supply and drainage pipeline total plane distribution, part of the trunk sewer section, and feed water pressure diagram and so on, learn to apply knowledge. 杭州市給水排水管網(wǎng)設(shè)計(jì) 4 目錄 第一章 課程設(shè)計(jì)任務(wù)書(shū) ...............................................................6 第二章 給水管網(wǎng)設(shè)計(jì)與計(jì)算 .......................................................8 供水方式的選擇 ....................................................................8 給水管網(wǎng)的布置 ....................................................................8 1)、水廠的選址原則 .................................................................8 2)、管網(wǎng)的定線要求 ..................................................................8 基本數(shù)據(jù)的確定 ...................................................................9 設(shè)計(jì)用水量計(jì)算 ...................................................................9 清水池的計(jì)算 : (見(jiàn)表 ) ...........................................10 管段設(shè)計(jì)流量計(jì)算 .............................................................12 各管段長(zhǎng)度(見(jiàn)表 ) ...........................................12 集中流量的計(jì)算 ..........................................................12 比流量的計(jì)算 ..............................................................13 (見(jiàn)表 ) ............................13 節(jié)點(diǎn)流量的計(jì)算(見(jiàn)表 ) ................................13 管網(wǎng)流量的分配計(jì)算 ..................................................14 確定管徑 .....................................................................14 杭州市給水排水管網(wǎng)設(shè)計(jì) 5 管網(wǎng)平差 .....................................................................15 管網(wǎng)核算消防校核 ......................................................23 第三章 污水管道的設(shè)計(jì) .............................................................32 排水體制的確定 : .............................................................32 污水管道的定線 ..................................................................32 街坊進(jìn)行編號(hào)并計(jì)算其面積(見(jiàn)表 ) ..........................32 劃分設(shè)計(jì)管段,計(jì)算設(shè)計(jì)流量 ...........................................33 污水管道的水力計(jì)算 ..........................................................33 水力計(jì)算設(shè)計(jì)參數(shù) ......................................................33 污水干管的水力計(jì)算(見(jiàn)表 ) ......................34 第四章 雨水管網(wǎng)的設(shè)計(jì) .............................................................35 雨水管網(wǎng)的定線: .............................................................35 主干管的相關(guān)參數(shù)的確定 .................................................35 雨水管道的水力計(jì)算設(shè)計(jì)參數(shù) ..........................................37 ...........................................................37 第五章 課程設(shè)計(jì)總結(jié) ................................................................38 杭州市給水排水管網(wǎng)設(shè)計(jì) 6 第一章 課程設(shè)計(jì)任務(wù)書(shū) 一、 設(shè)計(jì)題目 : 杭州 市給水排水管道工程設(shè)計(jì)。 二、 原始資料 城市總 平面圖 1 張,比例為 1: 10000。 城市各區(qū)人口密度、平均樓層和居住區(qū)房屋衛(wèi)生設(shè)備情況: 分區(qū) 人口密度(人/公頃) 平均樓層 給排水設(shè)備 淋浴設(shè)備 集中熱 水供應(yīng) Ⅰ 300 4 + + Ⅱ 400 7 + + + Ⅲ 城市中有下列工業(yè)企業(yè),其具體位置見(jiàn)平面圖: 1) A工廠,日用水量 16000噸 /天,最大班用水量: 7000 噸 /班,工人總數(shù) 3000 人,分三班工作,最大班 1200 人,其中熱車(chē)間占 30 %,使用淋浴者占 40 %;一般車(chē)間使用淋浴者占 20 %。 2) B 工廠, 日用水量 8000 噸 /天,最大班用水量: 3000 噸 /班,工人總數(shù)
