　　對(dui)于高層(ceng)建筑(zhu)，城市(shi)給水(shui)(shui)(shui)(shui)(shui)管(guan)網的水(shui)(shui)(shui)(shui)(shui)壓一(yi)般不(bu)能滿(man)足高區(qu)部分(fen)生活(huo)用(yong)水(shui)(shui)(shui)(shui)(shui)的要求，絕大多數采用(yong)分(fen)區(qu)給水(shui)(shui)(shui)(shui)(shui)方式，即低區(qu)部分(fen)直(zhi)按由(you)城市(shi)給水(shui)(shui)(shui)(shui)(shui)管(guan)網供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)，高區(qu)部分(fen)由(you)水(shui)(shui)(shui)(shui)(shui)泵(beng)加壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)。選擇給水(shui)(shui)(shui)(shui)(shui)方式是(shi)高層(ceng)建筑(zhu)生活(huo)自動(dong)給水(shui)(shui)(shui)(shui)(shui)設(she)備(bei)設(she)計(ji)的關(guan)鍵，它直(zhi)接關(guan)系(xi)到生活(huo)給水(shui)(shui)(shui)(shui)(shui)系(xi)統的使(shi)用(yong)和(he)工程造(zao)價(jia)。

　　就目前我國(guo)城市(shi)給(gei)(gei)水(shui)(shui)(shui)(shui)狀(zhuang)況而言，水(shui)(shui)(shui)(shui)壓(ya)(ya)一般可滿足建(jian)筑(zhu)五～六層(ceng)的生活用(yong)水(shui)(shui)(shui)(shui)要求，高區部分(fen)的供水(shui)(shui)(shui)(shui)應(ying)根據(ju)具體情況確(que)(que)定。《建(jian)筑(zhu)給(gei)(gei)水(shui)(shui)(shui)(shui)排(pai)水(shui)(shui)(shui)(shui)設計規(gui)范(fan)》（GBJ15－88）（以下簡(jian)稱(cheng)《規(gui)范(fan)》） 2.3.4條(tiao)規(gui)定：“高層(ceng)建(jian)筑(zhu)生活自動(dong)給(gei)(gei)水(shui)(shui)(shui)(shui)設備(bei)的豎向分(fen)區，應(ying)根據(ju)使用(yong)要求、材(cai)料設備(bei)性能、維修管理(li)、建(jian)筑(zhu)物層(ceng)數等條(tiao)件，結合利用(yong)室外給(gei)(gei)水(shui)(shui)(shui)(shui)管網的水(shui)(shui)(shui)(shui)壓(ya)(ya)合理(li)確(que)(que)定。分(fen)區較 低衛(wei)生器具配水(shui)(shui)(shui)(shui)點處的靜水(shui)(shui)(shui)(shui)壓(ya)(ya)，住(zhu)宅、旅館、醫院宜(yi)為(wei)300～350KPa；辦公樓宜(yi)為(wei)350～450KPa。”因(yin)此，根據(ju)《規(gui)范(fan)》規(gui)定的分(fen)區給(gei)(gei)水(shui)(shui)(shui)(shui)靜水(shui)(shui)(shui)(shui)壓(ya)(ya)，兼顧消防(fang)給(gei)(gei)水(shui)(shui)(shui)(shui)系統的給(gei)(gei)水(shui)(shui)(shui)(shui)方式，高(gao)層(ceng)建筑生活自(zi)動給水設(she)備高區(qu)部分應進(jin)行合理(li)的豎向分區(qu)。

高位(wei)水(shui)箱給水(shui)方式(shi)在實(shi)際應用中可以按以下情(qing)況(kuang)考慮

　　1、建筑高度(du)50m左(zuo)右的(de)高層建筑，高區(qu)部分(fen)可(ke)采(cai)用(yong)貯(zhu)水(shui)(shui)(shui)池——水(shui)(shui)(shui)泵——屋頂水(shui)(shui)(shui)箱(xiang)——減(jian)壓(ya)(ya)閥(fa)給(gei)水(shui)(shui)(shui)方式(shi)(shi)。如果低(di)(di)(di)區(qu)部分(fen)對供水(shui)(shui)(shui) 要(yao)求較(jiao)高，可(ke)以直接從屋頂水(shui)(shui)(shui)箱(xiang)引下(xia)一根立(li)管(guan)(guan)至低(di)(di)(di)區(qu)管(guan)(guan)網，該立(li)管(guan)(guan)上設電(dian)(dian)動閥(fa)門(men)和減(jian)壓(ya)(ya)閥(fa)，平時電(dian)(dian)動閥(fa)門(men)關(guan)閉，在城市給(gei)水(shui)(shui)(shui)管(guan)(guan)網停止(zhi)供水(shui)(shui)(shui)時打開電(dian)(dian)動閥(fa)門(men)向低(di)(di)(di)區(qu)供水(shui)(shui)(shui)。如圖1所示。此方式(shi)(shi)供水(shui)(shui)(shui)穩定可(ke)靠，充分(fen)利用(yong)了城市管(guan)(guan)網的(de)水(shui)(shui)(shui)壓(ya)(ya)，節省能源。這(zhe)種(zhong)方式(shi)(shi)普遍采(cai)用(yong)。

　　2、建(jian)筑(zhu)高(gao)(gao)度50～80m左右的(de)高(gao)(gao)層(ceng)建(jian)筑(zhu)，高(gao)(gao)區部(bu)分可(ke)采(cai)用(yong)(yong)(yong)貯(zhu)水(shui)(shui)(shui)池(chi)——水(shui)(shui)(shui)屋頂水(shui)(shui)(shui)箱(xiang)(xiang)——減壓(ya)(ya)閥(fa)給(gei)水(shui)(shui)(shui)方式(shi)(shi)(shi)或(huo)高(gao)(gao)位水(shui)(shui)(shui)箱(xiang)(xiang)并(bing)聯給(gei)水(shui)(shui)(shui)方式(shi)(shi)(shi)。并(bing)聯給(gei)水(shui)(shui)(shui)方式(shi)(shi)(shi)各分區為(wei)獨立(li)的(de)給(gei)水(shui)(shui)(shui)系(xi)統，供(gong)水(shui)(shui)(shui)穩定可(ke)靠，水(shui)(shui)(shui)泵集中布置，便了管(guan)理(li)維(wei)護，運行動(dong)力費川省。但須設(she)水(shui)(shui)(shui)泵——水(shui)(shui)(shui)箱(xiang)(xiang)兩套設(she)備，增加了水(shui)(shui)(shui)泵和水(shui)(shui)(shui)箱(xiang)(xiang)占用(yong)(yong)(yong)的(de)建(jian)筑(zhu)面(mian)積，造價增大(da)，這在大(da)城市尤為(wei)顯(xian)著。減壓(ya)(ya)閥(fa)給(gei)水(shui)(shui)(shui)方式(shi)(shi)(shi)系(xi)統簡單，設(she)備費用(yong)(yong)(yong)少，占地(di)(di)面(mian)積小(xiao)，管(guan)理(li)維(wei)護方便。但是其供(gong)水(shui)(shui)(shui)穩定性(xing)比并(bing)聯給(gei)水(shui)(shui)(shui)較(jiao)差，運行動(dong)力費用(yong)(yong)(yong)較(jiao)高(gao)(gao)。目前我國各地(di)(di)供(gong)電情(qing)況(kuang)逐(zhu)步改善(shan)，電費比較(jiao)適(shi)中，采(cai)用(yong)(yong)(yong)高(gao)(gao)位水(shui)(shui)(shui)箱(xiang)(xiang)分區減壓(ya)(ya)給(gei)水(shui)(shui)(shui)方式(shi)(shi)(shi)具有(you)(you)較(jiao)大(da)優越性(xing)。這種情(qing)況(kuang)病區部(bu)分有(you)(you)兩個分區。此(ci)種方式(shi)(shi)(shi)應用(yong)(yong)(yong)較(jiao)多。如由重慶建(jian)筑(zhu)大(da)學設(she)計(ji)的(de)重慶醫(yi)(yi)科大(da)學附屬 一醫(yi)(yi)院外(wai)科大(da)樓，總(zong)建(jian)筑(zhu)面(mian)積37756㎡，地(di)(di)下(xia)有(you)(you)兩層(ceng)，地(di)(di)上有(you)(you)二十(shi)三層(ceng)，建(jian)筑(zhu)高(gao)(gao)度89.1m。生活給(gei)水(shui)(shui)(shui)系(xi)統采(cai)用(yong)(yong)(yong)分區給(gei)水(shui)(shui)(shui)方式(shi)(shi)(shi)，四(si)層(ceng)及四(si)層(ceng)以下(xia)由城市管(guan)網直接(jie)供(gong)水(shui)(shui)(shui)，五(wu)(wu)層(ceng)及五(wu)(wu)層(ceng)以上由貯(zhu)水(shui)(shui)(shui)池(chi)——水(shui)(shui)(shui)泵——屋頂水(shui)(shui)(shui)箱(xiang)(xiang)——減壓(ya)(ya)閥(fa)減壓(ya)(ya)給(gei)水(shui)(shui)(shui)，高(gao)(gao)區部(bu)分有(you)(you)兩個分區。

　　3、建筑高度批80～110m左右(you)的(de)高層建筑，高區部分(fen)推薦采(cai)用高位(wei)水(shui)箱(xiang)分(fen)區減(jian)壓(ya)給(gei)水(shui)方式，即(ji)貯(zhu)水(shui)池——水(shui)泵——屋頂水(shui)箱(xiang)——減(jian)壓(ya)閥給(gei)水(shui)方式，如圖4所示。也可以采(cai)用高位(wei)水(shui)箱(xiang)并聯給(gei)水(shui)方式。這種(zhong)情況高區部分(fen)有三個分(fen)區。

　　4、建筑(zhu)高度超過(guo)110m的高層建筑(zhu)，較高分區(qu)水(shui)(shui)泵揚程將會很大，壓水(shui)(shui)管(guan)線(xian)很長，為(wei)避免這種情況應采用(yong)高位水(shui)(shui)箱串聯給水(shui)(shui)方(fang)式(shi)(shi)（不設中間(jian)水(shui)(shui)箱時(shi)采用(yong)中間(jian)接力水(shui)(shui)泵方(fang)式(shi)(shi)）。推(tui)薦采用(yong)高位水(shui)(shui)箱串聯給水(shui)(shui)與減壓給水(shui)(shui)相結(jie)合的方(fang)式(shi)(shi)。

　　高(gao)位水(shui)(shui)(shui)(shui)(shui)箱(xiang)串聯(lian)(lian)給水(shui)(shui)(shui)(shui)(shui)方(fang)式的(de)(de)特點(dian)(dian)是(shi)(shi)各(ge)分(fen)(fen)(fen)(fen)區(qu)(qu)的(de)(de)水(shui)(shui)(shui)(shui)(shui)泵(beng)分(fen)(fen)(fen)(fen)散設(she)置，各(ge)從下(xia)(xia)(xia)(xia)一(yi)(yi)分(fen)(fen)(fen)(fen)區(qu)(qu)的(de)(de)水(shui)(shui)(shui)(shui)(shui)箱(xiang)抽水(shui)(shui)(shui)(shui)(shui)，下(xia)(xia)(xia)(xia)一(yi)(yi)分(fen)(fen)(fen)(fen)區(qu)(qu)的(de)(de)水(shui)(shui)(shui)(shui)(shui)箱(xiang)除供本分(fen)(fen)(fen)(fen)區(qu)(qu)外同(tong)時(shi)是(shi)(shi)上一(yi)(yi)分(fen)(fen)(fen)(fen)區(qu)(qu)的(de)(de)水(shui)(shui)(shui)(shui)(shui)源，適用(yong)較高(gao)層(ceng)(ceng)建筑。其(qi)優點(dian)(dian)是(shi)(shi)避免了(le)設(she)揚(yang)(yang)程高(gao)的(de)(de)水(shui)(shui)(shui)(shui)(shui)泵(beng)和(he)水(shui)(shui)(shui)(shui)(shui)壓(ya)高(gao)的(de)(de)壓(ya)水(shui)(shui)(shui)(shui)(shui)管(guan)，壓(ya)水(shui)(shui)(shui)(shui)(shui)管(guan)也不會(hui)很長。其(qi)缺點(dian)(dian)是(shi)(shi)由于(yu)設(she)備(bei)(bei)分(fen)(fen)(fen)(fen)散，管(guan)理維(wei)護不便；水(shui)(shui)(shui)(shui)(shui)泵(beng)設(she)于(yu)樓層(ceng)(ceng)對防(fang)震、隔(ge)音(yin)要求高(gao)；上區(qu)(qu)供水(shui)(shui)(shui)(shui)(shui)受下(xia)(xia)(xia)(xia)區(qu)(qu)影(ying)響(xiang)，穩定性較差。串聯(lian)(lian)給水(shui)(shui)(shui)(shui)(shui)與減壓(ya)給水(shui)(shui)(shui)(shui)(shui)結合，由于(yu)設(she)備(bei)(bei)（水(shui)(shui)(shui)(shui)(shui)泵(beng)、水(shui)(shui)(shui)(shui)(shui)箱(xiang)）減少(shao)，節(jie)省造價，并有利于(yu)管(guan)理維(wei)護，也減小(xiao)了(le)震動和(he)噪聲的(de)(de)影(ying)響(xiang)，因(yin)較高(gao)層(ceng)(ceng)建筑中采用(yong)較多(duo)。以上四(si)種情況也有例外。如重慶(qing)揚(yang)(yang)子江假日(ri)飯店，建筑高(gao)度(du)79.65m，地(di)(di)下(xia)(xia)(xia)(xia)一(yi)(yi)層(ceng)(ceng)，地(di)(di)上二(er)十三層(ceng)(ceng)，地(di)(di)下(xia)(xia)(xia)(xia)一(yi)(yi)層(ceng)(ceng)至二(er)層(ceng)(ceng)由水(shui)(shui)(shui)(shui)(shui)泵(beng)——屋頂水(shui)(shui)(shui)(shui)(shui)箱(xiang)聯(lian)(lian)合供水(shui)(shui)(shui)(shui)(shui)，二(er)十一(yi)(yi)至二(er)十三層(ceng)(ceng)由氣壓(ya)給水(shui)(shui)(shui)(shui)(shui)設(she)備(bei)(bei)增壓(ya)供水(shui)(shui)(shui)(shui)(shui)。其(qi)低區(qu)(qu)較低配水(shui)(shui)(shui)(shui)(shui)點(dian)(dian)所受靜水(shui)(shui)(shui)(shui)(shui)壓(ya)達0.8MPa左右，這是(shi)(shi)由于(yu)該分(fen)(fen)(fen)(fen)區(qu)(qu)給水(shui)(shui)(shui)(shui)(shui)系統材料和(he)設(she)備(bei)(bei)承壓(ya)能力好并采取了(le)相應(ying)防(fang)振(zhen)隔(ge)音(yin)措施。

　　綜上所述(shu)，高(gao)(gao)(gao)(gao)層建(jian)(jian)筑(zhu)(zhu)生活自動給(gei)(gei)水(shui)(shui)(shui)(shui)設(she)備給(gei)(gei)水(shui)(shui)(shui)(shui)方式(shi)的(de)選擇應(ying)考慮(lv)多種(zhong)因(yin)素。當建(jian)(jian)筑(zhu)(zhu)高(gao)(gao)(gao)(gao)度50m左右時，低區利用城市給(gei)(gei)水(shui)(shui)(shui)(shui)管網水(shui)(shui)(shui)(shui)壓(ya)直接供(gong)(gong)水(shui)(shui)(shui)(shui)，高(gao)(gao)(gao)(gao)區采(cai)(cai)用水(shui)(shui)(shui)(shui)泵——屋(wu)頂水(shui)(shui)(shui)(shui)箱(xiang)聯合(he)供(gong)(gong)水(shui)(shui)(shui)(shui)；當建(jian)(jian)筑(zhu)(zhu)高(gao)(gao)(gao)(gao)度50-80m時，高(gao)(gao)(gao)(gao)區采(cai)(cai)用高(gao)(gao)(gao)(gao)位(wei)水(shui)(shui)(shui)(shui)箱(xiang)減壓(ya)閥給(gei)(gei)水(shui)(shui)(shui)(shui)方式(shi)；當建(jian)(jian)筑(zhu)(zhu)高(gao)(gao)(gao)(gao)度80-110m時，高(gao)(gao)(gao)(gao)區采(cai)(cai)用高(gao)(gao)(gao)(gao)位(wei)水(shui)(shui)(shui)(shui)箱(xiang)分區減壓(ya)給(gei)(gei)水(shui)(shui)(shui)(shui)方式(shi)：當建(jian)(jian)筑(zhu)(zhu)高(gao)(gao)(gao)(gao)度超過110m時，高(gao)(gao)(gao)(gao)區采(cai)(cai)用高(gao)(gao)(gao)(gao)位(wei)水(shui)(shui)(shui)(shui)箱(xiang)串聯給(gei)(gei)水(shui)(shui)(shui)(shui)與減壓(ya)給(gei)(gei)水(shui)(shui)(shui)(shui)相(xiang)結(jie)合(he)的(de)方式(shi)。總(zong)之，應(ying)根據(ju)《規范》規定(ding)(ding)并(bing)結(jie)合(he)當地的(de)實(shi)際(ji)情況及工程的(de)實(shi)際(ji)情況，確(que)定(ding)(ding)經濟合(he)理的(de)給(gei)(gei)水(shui)(shui)(shui)(shui)方式(shi)。
