鋼波紋管經濟耐用的原因是什么?
鋼波(bo)紋(wen)管具(ju)有施工工期(qi)短、重量輕(qing)、安裝方便、耐久性能(neng)(neng)好(hao)、工程造價低、抗(kang)變形能(neng)(neng)力強(qiang)、減少維(wei)護費用成(cheng)本等優點。鋼波(bo)紋(wen)管是一種柔性構造,波(bo)紋(wen)管在構造上具(ju)有橫向抵償(chang)位移特性,可充(chong)分發揮鋼材抗(kang)拉功能(neng)(neng)強(qiang)。
具有較大的抗(kang)(kang)變(bian)形(xing)和(he)抗(kang)(kang)沉降(jiang)才(cai)干(gan),施工(gong)過程中重(zhong)量(liang)輕、設備方便(bian)快捷(jie)、施工(gong)簡潔等許多優點(dian)。鋼波(bo)紋(wen)(wen)管(guan)按構(gou)成材料(liao)可分為(wei)(wei)金(jin)屬波(bo)紋(wen)(wen)管(guan)、非金(jin)屬波(bo)紋(wen)(wen)管(guan)兩種;按構(gou)造可分為(wei)(wei)單層(ceng)(ceng)和(he)多層(ceng)(ceng)。單層(ceng)(ceng)波(bo)紋(wen)(wen)管(guan)應用較多。多層(ceng)(ceng)波(bo)紋(wen)(wen)管(guan)強度高,耐久性好,應力小(xiao),用在重(zhong)要的測(ce)量(liang)中。
鋼(gang)波(bo)(bo)(bo)紋管(guan)的材(cai)料普通為(wei)青銅、黃銅、不銹鋼(gang)、蒙乃爾合(he)(he)金和(he)因康鎳(nie)爾合(he)(he)金等。鋼(gang)波(bo)(bo)(bo)紋管(guan)選用規(gui)范化(hua)設(she)計方案,出(chu)產制作,設(she)計方案簡易,出(chu)產制作周期時間短;工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)項(xiang)目具體工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)造價比類似跨距的橋,洞低;工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)(gong)短工(gong)(gong)(gong)(gong)(gong)期,要害為(wei)組裝(zhuang)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)(gong);金屬材(cai)料波(bo)(bo)(bo)紋管(guan)替(ti)代混凝土結構展開洞工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)(gong)。
