前 言 給水排水管道工程是給水排水工程的重要組成部分,可分為給水管道工程和排水管道工程兩大類。給水管道工程是論述水的提升,輸送,貯存,調(diào)節(jié)和分配的科學。其最基本的任務是保證水源的原料水送至水處理構(gòu)筑物及符合用戶用水水質(zhì)標準的水輸送和分配到用戶。這一任務是通過水泵站,輸水管,配水管網(wǎng)及調(diào)節(jié)構(gòu)筑物等設施的共同工作來實現(xiàn)的,它們組成了給水管道工程。設計和管理的基本要求是以最少的建造費用和管理費用,保證用戶所需的水量和水壓,保證水質(zhì)安全,降低漏損,并達到規(guī)定的可靠性。 給水排水管網(wǎng)工程是給水排水工程中很重要的組成部分,所需(建設)投資也很大,一般約占給水排水工程總投資的50%~80%。同時管網(wǎng)工程系統(tǒng)直接服務于民眾,與人們生活和生產(chǎn)活動息息相關,其中任一部分發(fā)生故障,都可能對人們生活、生產(chǎn)及保安消防等產(chǎn)生極大影響。因此,合理地進行給水排水管道工程規(guī)劃、設計、施工和運行管理,保證其系統(tǒng)安全經(jīng)濟地正常運行,滿足生活和生產(chǎn)的需要,無疑是非常重要的。 室外給水排水工程是城鎮(zhèn)建設的一個重要組成部分,其主要任務就是為城鎮(zhèn)提供足夠數(shù)量并符合一定水質(zhì)標準的水;同時,把人們在生活、生產(chǎn)過程中使用后的污水匯集并輸送到適當?shù)攸c進行凈化處理,達到一定水質(zhì)標準后,或重復使用,或灌溉農(nóng)田,或排入水體?! ? 室內(nèi)給水排水工程的任務是將室外給水系統(tǒng)輸配的凈水組織供應到室內(nèi)各個用水點,將用后的污水排除匯集到室外排水系統(tǒng)中去。做為工程類專業(yè)學生,實踐學習和設計是我們自身獲取知識和經(jīng)驗的最好環(huán)節(jié)。學生通過設計,綜合運用和深化所學的基本理論、基本技能,培養(yǎng)學生獨立分析和解決問題的能力,通過設計能使學生具有:①掌握查閱規(guī)范、標準設計圖集,產(chǎn)品目錄的方法,提高計算、繪圖和編寫設計說明的水平,作好一個工程師的基本訓練。②熟練城鎮(zhèn)給水排水工程系統(tǒng)的詳細計算和培養(yǎng)一定的理論分析和設計的能力。提高方案的比較、技術(shù)經(jīng)濟、環(huán)境、社會等諸方面的綜合分析和論證能力。③培養(yǎng)計算機操作和應用能力。熟練專業(yè)軟件應用。ForewordWater drains, water supply and drainage project is an important ponent of the project can be divided into drains and water supply pipeline project works two categories.Water pipeline project is on the upgrading of water, transmission, storage, distribution and regulation of science. Its most basic task is to ensure that the raw water source sent to the water treatment structures and water users with the water quality standard transmission and distribution to users. This task through the pump stations, pipelines, distribution mains network structure and regulation and other facilities to work together to achieve, and they formed a water pipeline project. Design and management is a basic requirement for at least the construction costs and management fees to ensure that the necessary water users and pressure to ensure water quality and safety, reduce leakage and achieve the required reliability.Water drainage network project is a water supply and drainage project in the very important ponent of the needs (building) there is also a great investment, the general water supply and drainage works about a total investment of 50% to 80%. At the same time network engineering systems direct services to the people, and people39。s lives and production activities are closely related, as part of a fault may be on people39。s lives, such as production and security have a great impact on fire. Therefore, the reasonable water drainage works for the planning, design, construction and operation of management, guarantee the security of its system to normal operation of the economy to meet the needs of life and production, and this is certainly very important.Outdoor urban water supply and drainage project is the construction of an important ponent of its main tasks is to provide adequate number of towns and meet certain water quality standards。 At the same time, people in the life of the production process to use the effluent water pooling and transported to a suitable site for purification of up to a certain quality standard, or repeated use, or irrigation or discharged into the water body. Indoor water supply and drainage project is the task of distribution of outdoor water supply system to supply water purification organizations in all indoor water, the sewage will be used to water to remove outdoor pool drainage systems.Does for the project class specialized student, the practice study and the design is our own knowledge acquisition and the experience best link. Moreover in the graduation project undergraduate course plan of instruction the essential link, after the undergraduate course stipulates the practical education which pletes the plete curriculum to have to carry on, the student through the graduation project, the synthesis utilizes the elementary theory, the basic skill which and deepens studies, trains the student independently to analyze and to solve the question ability, can enable the student through the graduation project to have:(1) Grasps the consult standard, the standard design atlas, the product catalog method, enhances the putation, the cartography and the pilation design explanation level, finishes an engineer39。s basic training.(2) Skilled cities give the water sewerage system the detailed putation and the raise certain theoretical analysis and the design ability. Enhances the plan the parison, the technical economy, the environment, the society and so on the various aspects generalized analysis and proves the ability.(3) Raise puter operation and application ability. Skilled specialized software application. 目 錄第1章 課程設計任務書 5第2章 給水管網(wǎng)設計與計算 7 給水管網(wǎng)布置及水廠選址 7 給水管網(wǎng)設計計算 8 清水池調(diào)節(jié)容積 11 11 12 管網(wǎng)水力計算 13: 13: 15 管網(wǎng)平差 17 17(最高用水時): 19 19 20 消防校核 21第3章 污水管網(wǎng)設計與計算 22 污水設計流量計算 22 污水管道水力計算 23 23第4章 雨水管網(wǎng)設計與計算 25 雨水設計流量計算 25 25 單位面積的徑流 25 雨水管道水力計算 26第五章 設計總結(jié) 27附錄 參考文獻 28附表一:一區(qū)管網(wǎng)平差結(jié)果 28附表二:二區(qū)管網(wǎng)平差結(jié)果 30附表三:一區(qū)消防校核平差結(jié)果 32附表四:二區(qū)消防校核平差結(jié)果 3435 / 40第1章 課程設計任務書一、 設計題目: 常熟 市給水排水管道工程設計。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)生設備情況:分區(qū)人口密度(人/公頃)平均樓層給排水設備淋浴設備集中熱水供應Ⅰ2205+++Ⅱ2004+++城市中有下列工業(yè)企業(yè),其具體位置見平面圖: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,其中熱車間占 30 %,使用淋浴者占 70 %;一般車間使用淋浴者占 20 %。2) B工廠,日用水量8000噸/天,最大班用水量: 噸/班,工人總數(shù) 人,分三班工作,最大班 人,熱車間占 %,使用淋浴者占 %;一般車間使用淋浴者占 %。3) 火車站用水量為 6 L/s。城市土質(zhì)種類為粘土,地下水位深度為 8 米。城市河流水位: 最高水位:55米,最低水位:40米,常水位: 45米。三、課程設計內(nèi)容:城市給水管網(wǎng)擴初設計1) 城市給水管網(wǎng)定線(包括方案比較);2) 用水量計算,管網(wǎng)水力計算;3) 清水池、水塔容積計算、水泵揚程計算4) 管網(wǎng)校核;5) 繪圖(平面圖、等水壓線圖)城市排水管網(wǎng)擴初設計。1) 排水體制選擇2) 城市排水管網(wǎng)定線的說明(包括方案比較);3) 設計流量計算;4) 控制分支管及總干管的水力計算;5) 任選1條雨水管路的水力計算(若體制為分流制);6) 繪圖(平面圖、縱剖面圖)四、設計參考資料《給排水設計手冊》第一冊或《給排水快速設計手冊》第5冊《給排水管道工程》教材五、設計成果設計說明書一份(包括前言、目錄、設計計算的過程、總結(jié))城市給水排水管道總平面布置圖1張,比例尺為1:10000(1號圖);給水管網(wǎng)等水壓線圖1張(2號圖);污水總干管縱剖面圖1張(由指導教師指定某一段,長度大約1000米左右)(2號圖);六、要求按正常上課嚴格考勤;設計說明書要求條理清楚,書寫端正,無錯別字;圖紙線條、符號、字體符合專業(yè)制圖規(guī)范);按時完成設計任務七、其他:設計時間:20102011學年第一學期(第
