鋼波紋管經濟耐(nai)用的原因是什么?
鋼波(bo)紋管(guan)具有(you)施工(gong)工(gong)期短、重量輕、安裝方便、耐(nai)久性能好(hao)、工(gong)程(cheng)造(zao)價低、抗變形能力強、減少維護費(fei)用成本等(deng)優(you)點。鋼波(bo)紋管(guan)是一(yi)種柔性構造(zao),波(bo)紋管(guan)在構造(zao)上具有(you)橫向抵償位移特性,可充分(fen)發揮鋼材(cai)抗拉(la)功能強。
具有較大的抗(kang)變形(xing)和抗(kang)沉(chen)降才干,施工過(guo)程(cheng)中(zhong)(zhong)重量輕、設(she)備方(fang)便快捷、施工簡潔等許多優點。鋼波紋(wen)管按構成材料可(ke)分(fen)為(wei)金(jin)屬波紋(wen)管、非金(jin)屬波紋(wen)管兩(liang)種;按構造可(ke)分(fen)為(wei)單(dan)(dan)層(ceng)和多層(ceng)。單(dan)(dan)層(ceng)波紋(wen)管應用較多。多層(ceng)波紋(wen)管強(qiang)度高,耐久性好,應力小,用在重要的測量中(zhong)(zhong)。
鋼(gang)波(bo)(bo)紋管的材料(liao)普通為青銅(tong)(tong)、黃銅(tong)(tong)、不銹鋼(gang)、蒙乃爾合金(jin)(jin)和因康(kang)鎳爾合金(jin)(jin)等。鋼(gang)波(bo)(bo)紋管選(xuan)用規范化設計方案,出(chu)產制作(zuo),設計方案簡易,出(chu)產制作(zuo)周期時間短(duan);工(gong)(gong)程(cheng)項目具體工(gong)(gong)程(cheng)造價比類似跨距的橋,洞低;工(gong)(gong)程(cheng)施(shi)工(gong)(gong)短(duan)工(gong)(gong)期,要害為組裝工(gong)(gong)程(cheng)施(shi)工(gong)(gong);金(jin)(jin)屬材料(liao)波(bo)(bo)紋管替代混(hun)凝土結構展開洞工(gong)(gong)程(cheng)施(shi)工(gong)(gong)。
