一(yi)、人(ren)防套管預埋要求是什么(me)？

鋼(gang)制(zhi)預埋(mai)(mai)人防(fang)設(she)備風(feng)管(guan)(guan)主要用于(yu)滿足各種人防(fang)工(gong)程中的(de)預埋(mai)(mai)和(he)穿管(guan)(guan)使用需求，鋼(gang)制(zhi)預埋(mai)(mai)人防(fang)設(she)備風(feng)管(guan)(guan)在(zai)預埋(mai)(mai)施工(gong)上與傳統預埋(mai)(mai)套管(guan)(guan)的(de)施工(gong)方式類似(si)，現貨供(gong)應人防(fang)設(she)備風(feng)管(guan)(guan)，人防(fang)設(she)備風(feng)管(guan)(guan)在(zai)外墻(qiang)施工(gong)時，凡穿墻(qiang)的(de)測(ce)壓(ya)管(guan)(guan)、取(qu)樣管(guan)(guan)與壓(ya)縮空氣管(guan)(guan)均(jun)直(zhi)接澆入(ru)密閉(bi)墻(qiang)內，不得預留孔洞后安裝。

二、人人防區(qu)特殊要求有(you)什(shen)么？

1、所有穿越人(ren)防(fang)區(qu)防(fang)護密閉(bi)隔(ge)墻(qiang)、密閉(bi)隔(ge)墻(qiang)及頂板的壓力管(guan)(guan)道均需預留防(fang)護密閉(bi)套管(guan)(guan)，防(fang)護套管(guan)(guan)做法(fa)參照圖集05FS02，重力排水不得穿越人(ren)防(fang)區(qu)隔(ge)墻(qiang)及頂板。

2、人防防爆地(di)(di)(di)漏(lou)安裝(zhuang)(zhuang)應符合(he)07FS02規定(ding)。防爆地(di)(di)(di)漏(lou)安裝(zhuang)(zhuang)需(xu)要注(zhu)意建(jian)筑后(hou)澆(jiao)層厚度(du)，控制(zhi)好地(di)(di)(di)漏(lou)安裝(zhuang)(zhuang)標高，甘(gan)肅(su)人防設備風管，安裝(zhuang)(zhuang)完(wan)畢后(hou)地(di)(di)(di)漏(lou)蓋需(xu)取下另行存放，地(di)(di)(di)漏(lou)內采用編織袋(dai)內裝(zhuang)(zhuang)鋸木屑填塞飽滿密實，以防堵塞。待建(jian)筑地(di)(di)(di)面(mian)完(wan)成后(hou)再安裝(zhuang)(zhuang)地(di)(di)(di)漏(lou)蓋。

3、人防區(qu)暗裝電(dian)氣管路均(jun)采用壁(bi)厚不小(xiao)于2.5mm的(de)熱鍍鋅鋼管，穿(chuan)(chuan)過(guo)人防隔墻(qiang)及頂板的(de)電(dian)氣管線(xian)，需(xu)按照07SFD10規定做防護(hu)密閉處理，明配管需(xu)預(yu)留(liu)穿(chuan)(chuan)人防隔墻(qiang)及頂板的(de)密閉套管，密閉套管做法詳07SFD10。并(bing)需(xu)注意(yi)戰時如信(xin)號管、檢測管等(deng)穿(chuan)(chuan)防護(hu)墻(qiang)的(de)備用預(yu)留(liu)管。

4、人(ren)(ren)防(fang)區戰(zhan)時安裝(zhuang)的(de)風管(guan)穿防(fang)護墻處(chu)需(xu)隨結(jie)構施工預留(liu)符合密閉要求的(de)預留(liu)管(guan)，預留(liu)管(guan)尺寸、坐標、標高均需(xu)核對各(ge)圖紙做綜合排布，人(ren)(ren)防(fang)設備風管(guan)加(jia)工廠家，以免造成各(ge)間管(guan)線(xian)沖突，人(ren)(ren)防(fang)通風各(ge)種預留(liu)管(guan)道(dao)均需(xu)符合人(ren)(ren)防(fang)規范要求。

人防設備風(feng)管(guan)自從(cong)該產(chan)品問世以來(lai)，就(jiu)以非(fei)(fei)常迅猛的(de)(de)姿態一下(xia)子(zi)席卷整個市場(chang)。這(zhe)不僅因為(wei)其自身功能的(de)(de)突出特點，也因為(wei)其低廉的(de)(de)價格非(fei)(fei)常適合推廣(guang)(guang)并普(pu)及，因而非(fei)(fei)常受到諸多廠(chang)家的(de)(de)歡迎。該產(chan)品的(de)(de)應用領(ling)域非(fei)(fei)常廣(guang)(guang)泛，主(zhu)要集中(zhong)在(zai)空調以及通風(feng)系統中(zhong)。其產(chan)品也幾(ji)乎涵蓋(gai)了所(suo)有行(xing)業領(ling)域，擁有非(fei)(fei)常大的(de)(de)普(pu)及率(lv)。那(nei)么(me)人防設備風(feng)管(guan)的(de)(de)面(mian)積是怎么(me)計算的(de)(de)呢(ni)？下(xia)面(mian)就(jiu)有小編和大家談(tan)談(tan)這(zhe)個方面(mian)的(de)(de)知識。

一、先根(gen)據建筑特(te)點、用(yong)途、防火(huo)分區情(qing)況以及功能要求(qiu)，計(ji)算(suan)所(suo)需要的風量;

二、然后根據(ju)設計(ji)規范中(zhong)對不同材質(zhi)通風(feng)管速的要求，確定(ding)風(feng)速;

三、有了風(feng)量和(he)風(feng)速，自(zi)然也就能計算出所需的面(mian)積(ji)了;

四、比如建筑(zhu)所需風量為10000立(li)方(fang)米/小時，采用的是鍍鋅(xin)鋼(gang)板通(tong)風道，結合建筑(zhu)使用功能(neng)的要(yao)求(qiu)，確定風速(su)為10米/秒(miao).則人防設(she)備風管的面積為：10000/(3600×10)=0.278每平方(fang)。

通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)是中空(kong)(kong)的(de)用于通(tong)(tong)(tong)風(feng)(feng)(feng)的(de)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)材(cai)，多為圓形(xing)(xing)或方(fang)形(xing)(xing)。通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)制作與安裝所用板材(cai)、型材(cai)以及其它主要成品(pin)材(cai)料，應符合設(she)(she)計及相關(guan)產品(pin)國家(jia)現行(xing)標準(zhun)的(de)規(gui)定(ding)，3mm人防設(she)(she)備風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)價格，并應用出(chu)廠檢驗(yan)合格證明，材(cai)料進場時(shi)應按(an)(an)國家(jia)現行(xing)有關(guan)標準(zhun)進行(xing)驗(yan)收(shou)。 　　1.按(an)(an)材(cai)質分(fen)　　通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)一(yi)般有：船(chuan)用通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)有正壓通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)和(he)負(fu)壓通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)及PE薄膜通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、鍍(du)鋅板（白鐵）風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、不銹鋼通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、玻璃鋼通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、塑料通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、復合材(cai)料通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、彩(cai)鋼夾心保(bao)(bao)溫板通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、涂膠布(bu)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)（如礦(kuang)用風(feng)(feng)(feng)筒(tong)）、礦(kuang)用塑料通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)等(deng)(deng)；伸(shen)縮通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)，阻燃風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)， 鋁箔復合保(bao)(bao)溫管(guan)(guan)(guan)(guan)(guan)(guan)(guan)；中央空(kong)(kong)調保(bao)(bao)溫軟(ruan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。　　2.按(an)(an)用途(tu)分(fen)　　通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)一(yi)般有：凈化系統送回風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、中央空(kong)(kong)調通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、工業(ye)送排(pai)(pai)風(feng)(feng)(feng)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、環保(bao)(bao)系統吸排(pai)(pai)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、礦(kuang)用抽放管(guan)(guan)(guan)(guan)(guan)(guan)(guan)、礦(kuang)用涂膠布(bu)風(feng)(feng)(feng)筒(tong)；消防煙道通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)等(deng)(deng)。　　3.按(an)(an)形(xing)(xing)狀分(fen)　　通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)一(yi)般有：圓形(xing)(xing)、矩形(xing)(xing)、螺旋形(xing)(xing)、波紋形(xing)(xing)等(deng)(deng)。
