鋼波紋管經(jing)濟耐用的原因是什(shen)么？

鋼波(bo)(bo)紋(wen)管(guan)具有(you)施工(gong)工(gong)期(qi)短、重量輕、安裝方便、耐(nai)久性(xing)能好、工(gong)程(cheng)造價低、抗變形能力(li)強、減少維(wei)護費用成(cheng)本等優點。鋼波(bo)(bo)紋(wen)管(guan)是(shi)一種(zhong)柔性(xing)構造,波(bo)(bo)紋(wen)管(guan)在構造上(shang)具有(you)橫向抵(di)償位移特性(xing),可(ke)充(chong)分發(fa)揮鋼材抗拉功能強。

鋼波紋管

具有較(jiao)大的抗(kang)變形(xing)和抗(kang)沉降才(cai)干,施工過程中重量(liang)(liang)輕、設備方便快捷、施工簡潔等許多(duo)優點。鋼波(bo)紋(wen)管按構成材料可分為(wei)金屬(shu)波(bo)紋(wen)管、非金屬(shu)波(bo)紋(wen)管兩種；按構造可分為(wei)單層(ceng)和多(duo)層(ceng)。單層(ceng)波(bo)紋(wen)管應用較(jiao)多(duo)。多(duo)層(ceng)波(bo)紋(wen)管強度(du)高，耐久性好，應力(li)小，用在重要(yao)的測量(liang)(liang)中。

鋼(gang)(gang)波紋(wen)管(guan)的材(cai)料普通為(wei)青銅、黃銅、不銹鋼(gang)(gang)、蒙乃(nai)爾合金(jin)和因康鎳爾合金(jin)等(deng)。鋼(gang)(gang)波紋(wen)管(guan)選(xuan)用規(gui)范化設計方案，出(chu)產制(zhi)作，設計方案簡(jian)易，出(chu)產制(zhi)作周(zhou)期時(shi)間短；工(gong)(gong)(gong)程(cheng)項目具體工(gong)(gong)(gong)程(cheng)造價比類似(si)跨距的橋，洞(dong)低；工(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)短工(gong)(gong)(gong)期，要害(hai)為(wei)組裝工(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)；金(jin)屬材(cai)料波紋(wen)管(guan)替代混凝土(tu)結(jie)構展(zhan)開洞(dong)工(gong)(gong)(gong)程(cheng)施工(gong)(gong)(gong)。
