鋼波紋管經(jing)濟耐用的原(yuan)因(yin)是什么？

鋼波紋(wen)管(guan)具有施工(gong)(gong)工(gong)(gong)期(qi)短、重量(liang)輕、安裝方便、耐久性能(neng)好、工(gong)(gong)程造價低(di)、抗(kang)(kang)變形能(neng)力強、減少(shao)維護(hu)費用成本(ben)等優點。鋼波紋(wen)管(guan)是一(yi)種柔性構(gou)造,波紋(wen)管(guan)在構(gou)造上具有橫向抵償位移特性,可(ke)充分發揮鋼材(cai)抗(kang)(kang)拉功能(neng)強。

鋼波紋管

具有較大的抗(kang)變(bian)形(xing)和(he)抗(kang)沉降才(cai)干(gan),施工(gong)過(guo)程(cheng)中重量輕、設(she)備方便快捷、施工(gong)簡潔等許多(duo)優點。鋼波(bo)紋(wen)(wen)管按構成材料可分為(wei)金屬(shu)(shu)波(bo)紋(wen)(wen)管、非金屬(shu)(shu)波(bo)紋(wen)(wen)管兩種；按構造(zao)可分為(wei)單(dan)層(ceng)(ceng)和(he)多(duo)層(ceng)(ceng)。單(dan)層(ceng)(ceng)波(bo)紋(wen)(wen)管應用較多(duo)。多(duo)層(ceng)(ceng)波(bo)紋(wen)(wen)管強度高，耐久性好，應力小，用在重要(yao)的測量中。

鋼(gang)波(bo)紋管(guan)的(de)材料普通為青(qing)銅、黃銅、不銹鋼(gang)、蒙乃(nai)爾合(he)(he)金和因康鎳爾合(he)(he)金等。鋼(gang)波(bo)紋管(guan)選用規(gui)范化設(she)計方案(an)，出(chu)產制作(zuo)，設(she)計方案(an)簡(jian)易(yi)，出(chu)產制作(zuo)周期時間短；工(gong)(gong)程項目具體工(gong)(gong)程造價(jia)比(bi)類(lei)似跨距的(de)橋，洞低；工(gong)(gong)程施工(gong)(gong)短工(gong)(gong)期，要害為組(zu)裝工(gong)(gong)程施工(gong)(gong)；金屬材料波(bo)紋管(guan)替代(dai)混凝(ning)土(tu)結構展(zhan)開洞工(gong)(gong)程施工(gong)(gong)。
