【正文】 設(shè)計總說明 本次畢業(yè)設(shè)計所選題目為囊謙縣香達鎮(zhèn)給水工程設(shè)計， 囊謙縣香達鎮(zhèn) 地處東經(jīng) 95176。21′58″～97176。07′0″，北緯 31176。32′20″～ 32176。43′46″，位于青海省最南端，玉樹州東南部 ，為瀾滄江發(fā)展源頭地區(qū) 。合理評價囊謙縣的地區(qū) 優(yōu)勢 ，資源條件和不利因素，結(jié)合囊謙縣國民經(jīng)濟發(fā)展“十一五”規(guī)劃，提出的發(fā)展方向 ，制定出香達鎮(zhèn) 總體發(fā)展布局，以達到強化縣域經(jīng)濟中心功能、推動全縣社會經(jīng)濟發(fā)展的目的，而現(xiàn)如今的市政給水系統(tǒng)不能滿足以后的發(fā)展需要，故需重新規(guī)劃設(shè)計。 城鎮(zhèn)總體規(guī)劃不僅是城市一定時期內(nèi)建設(shè)發(fā)展的戰(zhàn)略藍圖，而且是指導(dǎo)城鎮(zhèn)建設(shè)與管理的綱領(lǐng)性文件和城鎮(zhèn)社會經(jīng)濟發(fā)展與城鎮(zhèn)建設(shè)的基礎(chǔ)依據(jù) 。而給水系統(tǒng)的規(guī)劃是城鎮(zhèn)總歸的重要組成部分，所以秉承與社會國民經(jīng)濟發(fā)展相協(xié)調(diào)的原則、超前性與現(xiàn)實相結(jié)合的原則、 堅持高標準，高起點原則。制定出從實際出發(fā)，并且結(jié)合遠景規(guī)劃的，具有可操作性的設(shè)計規(guī)劃。 本設(shè)計的設(shè)計目的是把囊謙縣香達鎮(zhèn)給水系統(tǒng)建設(shè)成結(jié)構(gòu)合 理，符合城鎮(zhèn)功能分區(qū)需求，布局合理，并且能夠滿足遠期規(guī)劃發(fā)展需要的給水系統(tǒng)，并以此為標準力求設(shè)計完整。 香達鎮(zhèn)是囊謙縣的政治、文化 、經(jīng)濟中心，規(guī)劃中人口包括常住人口和暫住人口，近期規(guī)劃城鎮(zhèn)人口達 萬人；遠期規(guī)劃城鎮(zhèn)人口為 萬人，城鎮(zhèn)建設(shè)總用地為 公頃、人均為 平米，而其中居住安排用地為 公頃，人均為 公頃，其中規(guī)劃最高建筑為 5 層故設(shè)計最低自由水頭為 24 米，且為了供水安全與經(jīng)濟因素考慮本設(shè)計采用環(huán)狀管網(wǎng)與枝狀管網(wǎng)相結(jié)合的原則布置，在居民區(qū)集中地區(qū)設(shè)置環(huán)網(wǎng)其余地方設(shè)置枝 狀管網(wǎng)。香達鎮(zhèn)中扎曲河作為唯一流經(jīng)此處的河流，故選用扎曲河作為取水源地，并在上游地區(qū)就近建立取水泵站與凈水廠。 本設(shè)計設(shè)計內(nèi)容分三個部分：取水工程設(shè)計、給水廠設(shè)計、城鎮(zhèn) 輸配水 管網(wǎng)設(shè)計。 主要內(nèi)容有：水源地選擇、取水方式及構(gòu)筑物設(shè)計、確定水廠規(guī)模，選擇凈化工藝流程及凈化構(gòu)筑物型式、主要構(gòu)筑物的設(shè)計計算與高程計算、城鎮(zhèn)輸配水管網(wǎng)的布置形式設(shè)計、主要干管、支管的設(shè)計流量及管徑、高程計算。 本設(shè)計設(shè)計成果為設(shè)計計算書以及 13 張附屬圖紙。包括：囊謙縣香達鎮(zhèn)總體規(guī)劃圖、水廠平面布置圖、網(wǎng)格絮凝斜管沉淀池平剖面圖、普通快濾 池平剖面圖、清水池平剖面圖、水廠高程布置圖、管網(wǎng)平面布置圖、管網(wǎng)最高用水時平差圖。 Specification The graduation project titled Nangq234。n selected incense up to the town water supply engineering, Nangq234。n incense up to the town located in east longitude 95 176。 2139。58 ~ 97 176。 0739。0, latitude 31 176。 3239。20 ~ 32 176。 4339。46 , located in the southernmost tip of Qinghai Province, Yushu southeastern source area for the development of the Lancang River. Reasonable evaluation Nangq234。n regional advantages, resource conditions and unfavorable factors, bined Nangq234。n economic development Eleventh FiveYear plan, put forward the development direction of the town to develop a fragrance of the overall layout of the development, the economic center of the county in order to achieve enhanced functionality to promote the county39。s social and economic development purposes, and is now a municipal water supply system can not meet the development needs of the future, so the need to replan design. Not only is the city overall planning of urban construction and development of a strategic blueprint for a certain period, and urban construction and management to guide programmatic document and urban social and economic development and urban construction sound basis. The water supply system planning is an important part of town is always so adhering to national economic development and social harmony principle ahead of time and reality principle of bining, adhere to high standards, high starting point principles. Worked out from reality, and the bination of vision, with a workable design and planning. This design is designed to put Nangq234。n incense up to the town water supply system into a rational structure, in line with urban function zoning requirements, the layout is reasonable, and longterm planning to meet the development needs of water supply system, and as a standard and strive to design integrity. Incense of town is Nangq234。n political, cultural and economic center, the planned population consists of the resident population and transient population, recent planning urban population of million people。 term planning urban population of million people, of land for urban construction total hectares per capita of square meters, of which hectares of land for living arrangements, the per capita of hectares, of which the tallest building planned for the five lowest free layer so the design head of 24 meters, and water security and economic factors in order to consider the design uses ring shaped branched pipe work and the principle of bining the pipe work layout, set in a residential area focused the rest of the ring work settings branched pipe work. Incense of the river as the only town in Zhaqu rivers flowing through here, so use Zhaqu river as a water source to take, and in the upstream areas near water pumping station and water purification plants to establish. This design Design content is divided into three parts: water engineering, waterworks design, urban design Water Distribution Networks. Main contents are: water source selection, water ways and structures designed to determine the water scale purification process and purifying selection type structures, the main structures of the design calculations and elevation calculations, urban water distribution work layout form design, the main trunk , the design flow and the branch pipe diameter, height putation. The design of the design results for the design calculations and 13 attached drawings. Including: Nangq234。n incense up to the town master plan, water floorplan grid flocculation Sedimentation tank flat profile, ordinary rapid filter flat profile, clear pool flat profile, water elevation layout, pipe work plane layout, the highest when the water pipe work adjustment chart. 目錄 1 概述 .....................................................................................................................................................................1 基礎(chǔ)資料 ......................................................................................................................................................1 工程設(shè)計 ......................................................................................................................................................2 2 設(shè)計用水量 .........................................................................................................................................................3 用水量計算 ..................................................................................................................................................3 各項用水量計算 ..................................................................................................................
