配水管網(wǎng)的設(shè)計及計算案例綜述第1章緒論工程設(shè)計期限設(shè)計期限：近期至2015年，中期至2020年，遠期至2030年。工程服務(wù)范圍A縣可門港經(jīng)濟區(qū)，包括馬鼻、透堡、官坂、筱埕、黃岐、苔菉、坑園、安凱、下宮等9個鄉(xiāng)鎮(zhèn)。第二章配水管網(wǎng)設(shè)計2.1管網(wǎng)定線目前常用的管網(wǎng)定線形式有枝狀管網(wǎng)和環(huán)狀管網(wǎng)。枝狀管網(wǎng)的優(yōu)點是造價較低，施工方便。但供水安全性較差，一旦出現(xiàn)管網(wǎng)中途漏損，將會嚴重影響不利點的供水。環(huán)狀管網(wǎng)的供水安全性較高，供水水壓相對穩(wěn)定，但造價相對較高，施工過程復雜?？紤]到可門港經(jīng)濟區(qū)的主要用地類型為居住和制造業(yè)，根據(jù)可門港經(jīng)濟區(qū)的地形情況，結(jié)合可門港地區(qū)其余水廠的用水量平衡分析，本設(shè)計定線采用環(huán)狀管網(wǎng)配水的形式。2.2管材選擇由于本設(shè)計規(guī)劃的范圍較大，管線長度較長，因此設(shè)計的管徑較大。因此需要進行管材的方案比選，采取既經(jīng)濟，水頭損失又小的方案。目前常見的管材有很多，考慮到造價和地形因素，本設(shè)計僅對鋼管、PE管和球墨鑄鐵管進行比較。表2-1管材比選表管材名稱優(yōu)缺點適用流速備注鋼管優(yōu)點：1.機械強度高，使用壽命較長2.內(nèi)襯圖層后抗腐蝕性強缺點：1.施工不方便，重量大2.焊接的強度要求比較嚴格0.8m/s~3.0m/sPE管優(yōu)點：1.現(xiàn)狀應(yīng)用比較廣泛耐腐蝕性強，可以適應(yīng)各種腐蝕性的條件重量輕，水頭損失比較小缺點：適合用于溫度較低的條件0.8m/s~3.0m/s球墨鑄鐵管優(yōu)點：1.耐腐蝕性的能力強2.建造成本低，安裝方便3.機械性能好缺點：壁厚較大，內(nèi)襯涂層防腐效果一般0.6m/s~1.4m/s推薦管材綜合考慮，雖然管徑過小或過大的情況會導致球墨鑄鐵管的造價比較高，但球墨鑄鐵管的機械性能和技術(shù)性能較好，且耐腐蝕性強，結(jié)合造價概算的情況考慮，本設(shè)計配水管網(wǎng)決定采用球墨鑄鐵管。第三章配水管網(wǎng)計算3.1流量計算配水管網(wǎng)設(shè)計流量按最高日最高時流量計算，參考《GB50013-2018室外給水設(shè)計標準》4.0.9：Q=1.6×40000=64000m3/d=740.74L/s3.2配水干管的有效長度計算根據(jù)上述的定線原則，確定供水方向，同時進行經(jīng)濟比選，并列表統(tǒng)計各管段的實際和有效長度，用設(shè)計軟件計算流量、比流量、沿線流量和節(jié)點流量。表3-1各管段長度和配水長度管道編號管長（m）有效管長（m）管道編號管長（m）有效管長（m）JS1-JS2799799JS35-JS36503503JS2-JS3360360JS36-JS26518518JS3-JS4907907JS32-JS38689689JS4-JS5507507JS38-JS3912041204JS5-JS6502502JS39-JS40474474JS6-JS7488488JS40-JS41384384JS7-JS8502502JS41-JS42288288JS8-JS9431431JS42-JS43972972JS9-JS10418418JS43-JS44975975JS10-JS11431431JS44-JS4510071007JS11-JS12535535JS45-JS4616301630JS12-JS13503503JS46-JS4711031103JS13-JS14499499JS47-JS4818881888JS14-JS15495495JS48-JS49602602JS15-JS16232232JS49-JS50694694JS16-JS17500500JS50-JS51581581JS17-JS18608608JS51-JS52752752JS18-JS26867867JS52-JS53656656JS26-JS3714790JS53-JS6916761676JS37-JS45443443JS47-JS54568568JS2-JS19885885JS54-JS55548548JS19-JS20343343JS55-JS5611081108JS20-JS21567567JS56-JS57978978JS21-JS22493493JS57-JS58655655JS22-JS23499499JS58-JS69521521JS23-JS24501501JS46-JS59678339JS24-JS25795795JS59-JS60336168JS25-JS26488488JS60-JS61559279.5JS19-JS27638638JS61-JS6211591159JS27-JS28341341JS62-JS6310481048JS28-JS29498498JS63-JS64505505JS29-JS30656656JS64-JS65651651JS30-JS31211211JS65-JS66489489JS31-JS3210371037JS66-JS67686686JS32-JS33339339JS67-JS68929929JS33-JS34354354JS68-JS69608608JS34-JS354124123.3比流量計算qcb式中，qcb——長度比流量，L/（s.m）Q——管網(wǎng)總用水量，L/s∑Qi——工業(yè)企業(yè)及其他大用戶的集中流量之和，L/s∑L——管網(wǎng)配水干管總計算長度，m。一側(cè)配水的管段（例如只有一側(cè)配水的管道）計入實際長度的一半。對于兩側(cè)配水的管段，計算長度與實際長度相對應(yīng)；兩邊沒有配水的管道的長度不計算在內(nèi)（即不穿越廣場、公園等無建筑物地區(qū)的管線長度）。q各管段的沿線流量計算如下表：表3-2沿線流量分配管道編號管長（m）有效管長（m）比流量沿線流量（L/s）JS1-JS27997990.01612.784JS2-JS33603600.0165.760JS3-JS49079070.01614.512JS4-JS55075070.0168.112JS5-JS65025020.0168.032JS6-JS74884880.0167.808JS7-JS85025020.0168.032JS8-JS94314310.0166.896JS9-JS104184180.0166.688JS10-JS114314310.0166.896JS11-JS125355350.0168.560JS12-JS135035030.0168.048JS13-JS144994990.0167.984JS14-JS154954950.0167.920JS15-JS162322320.0163.712JS16-JS175005000.0168.000JS17-JS186086080.0169.728JS18-JS268678670.01613.872JS26-JS37147900.0160JS37-JS454434430.0167.088JS2-JS198858850.01614.16JS19-JS203433430.0165.488JS20-JS215675670.0169.072JS21-JS224934930.0167.888JS22-JS234994990.0167.984JS23-JS245015010.0168.016JS24-JS257957950.01612.72JS25-JS264884880.0167.808JS19-JS276386380.01610.208JS27-JS283413410.0165.456JS28-JS294984980.0167.968JS29-JS306566560.01610.496JS30-JS312112110.0163.376JS31-JS32103710370.01616.592JS32-JS333393390.0165.424JS33-JS343543540.0165.664JS34-JS354124120.0166.592JS35-JS365035030.0168.048JS36-JS265185180.0168.288JS32-JS386896890.01611.024JS38-JS39120412040.01619.264JS39-JS404744740.0167.584JS40-JS413843840.0166.144JS41-JS422882880.0164.608JS42-JS439729720.01615.552JS43-JS449759750.01615.600JS44-JS45100710070.01616.112JS45-JS46163016300.01626.080JS46-JS47110311030.01617.648JS47-JS48188818880.01630.208JS48-JS496026020.0169.632JS49-JS506946940.01611.104JS50-JS515815810.0169.296JS51-JS527527520.01612.032JS52-JS536566560.01610.496JS53-JS69167616760.01626.816JS47-JS545685680.0169.088JS54-JS555485480.0168.768JS55-JS56110811080.01617.728JS56-JS579789780.01615.647JS57-JS586556550.01610.480JS58-JS695215210.0168.336JS46-JS596783390.0165.424JS59-JS603361680.0162.688JS60-JS61559279.50.0164.472JS61-JS62115911590.01618.544JS62-JS63104810480.01616.768JS63-JS645055050.0168.080JS64-JS656516510.01610.416JS65-JS664894890.0167.824JS66-JS676866860.01610.976JS67-JS689299290.01614.864JS68-JS696086080.0169.7283.4節(jié)點設(shè)計流量計算干管布置及節(jié)點分布如下圖所示：各節(jié)點的節(jié)點流量計算表如下：表3-3節(jié)點設(shè)計流量計算節(jié)點編號節(jié)點總流量（L/s）JS16.392JS216.352JS310.136JS411.312JS58.072JS67.920JS77.920JS87.464JS96.792JS106.792JS117.728JS128.304JS138.016JS147.952JS155.816JS165.856JS178.864JS1811.800JS1914.928JS207.280JS218.480JS227.936JS238.000JS2410.368JS2520.528JS2614.984JS277.832JS286.712JS299.232JS306.936JS319.984JS3216.525JS335.544JS346.128JS357.320JS368.168JS373.544JS3815.144JS3913.424JS406.864JS4
