一、隔音屏施工單位需要什么資質
一般來說隔音屏工(gong)(gong)程(cheng)(cheng)招標的話(hua)需要(yao)環(huan)(huan)(huan)(huan)保(bao)資(zi)(zi)質(zhi),施(shi)(shi)工(gong)(gong)資(zi)(zi)質(zhi),隔音公司三證(zheng)(營(ying)業執照、組(zu)織機構代碼(ma)證(zheng)、稅(shui)務登記證(zheng))比較重(zhong)要(yao)的是:環(huan)(huan)(huan)(huan)保(bao)工(gong)(gong)程(cheng)(cheng)專業承包(bao)資(zi)(zi)質(zhi)(三級及以(yi)(yi)上就(jiu)可(ke)(ke)以(yi)(yi)了(le)),安全生(sheng)產許(xu)可(ke)(ke)證(zheng),環(huan)(huan)(huan)(huan)保(bao)工(gong)(gong)程(cheng)(cheng)設計(ji)資(zi)(zi)質(zhi)等。因為(wei)降(jiang)噪一(yi)般就(jiu)是進行(xing)噪聲防治,降(jiang)噪屬(shu)于環(huan)(huan)(huan)(huan)境保(bao)護工(gong)(gong)程(cheng)(cheng),所以(yi)(yi)從事(shi)降(jiang)噪工(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)的單(dan)位應(ying)當具有(you)環(huan)(huan)(huan)(huan)保(bao)工(gong)(gong)程(cheng)(cheng)專業承包(bao)資(zi)(zi)質(zhi)。不過一(yi)般都(dou)沒有(you)那么嚴格,如(ru)果(guo)需要(yao)招標的話(hua)可(ke)(ke)能要(yao)出具這些(xie)證(zheng)件,一(yi)些(xie)小的項目比如(ru)小區(qu)隔音屏(ping)(ping),冷卻塔隔音屏(ping)(ping)等一(yi)般都(dou)不會要(yao)求(qiu)這些(xie),只需要(yao)具備建筑施(shi)(shi)工(gong)(gong)資(zi)(zi)格就(jiu)可(ke)(ke)以(yi)(yi)了(le)。
二、隔音屏工程驗收要檢測什么
要做到隔音屏正常驗收(shou),常做的(de)(de)檢測項目(mu)(mu)有(you)很多(duo),比如說隔聲性(xing)能(neng)、降噪系(xi)數(shu)、計權(quan)隔聲量、防(fang)(fang)腐性(xing)能(neng)、防(fang)(fang)火性(xing)能(neng)、抗(kang)風壓性(xing)能(neng)、抗(kang)彎(wan)承載力、拉伸(shen)強度、斷裂(lie)伸(shen)長率等。這(zhe)些(xie)都是比較(jiao)常做的(de)(de)項目(mu)(mu),特別是鐵(tie)路或者公路上(shang)的(de)(de)隔音屏,要求(qiu)比較(jiao)嚴格,這(zhe)些(xie)項目(mu)(mu)一般都是要做的(de)(de),這(zhe)些(xie)項目(mu)(mu)中,像力學這(zhe)塊都是比較(jiao)常規的(de)(de)項目(mu)(mu)。
