鋼波紋管從材(cai)料與結構(gou)(gou)和功能的(de)本質關系上分析,選用柔性高強度的(de)鋼波紋管洞因為軸向(xiang)波紋的(de)存在,使其具有受力特征,軸向(xiang)和徑向(xiang)同(tong)時分布因荷(he)載引起(qi)的(de)應(ying)力應(ying)變,可以更大程度上渙散荷(he)載的(de)應(ying)力會集(ji),更好地發揮鋼結構(gou)(gou)的(de)優勢。
鋼波紋管經濟耐用的原因無人問津
鋼波(bo)紋(wen)管具有(you)施工(gong)工(gong)期短、重(zhong)量輕(qing)、安(an)裝方(fang)便、耐(nai)久性能(neng)好、工(gong)程造價低、抗(kang)變形能(neng)力(li)強(qiang)、減(jian)少維(wei)護(hu)費用成本等優點。鋼波(bo)紋(wen)管是一種柔性構造,波(bo)紋(wen)管在構造上具有(you)橫(heng)向抵償位移特性,可充(chong)分發揮(hui)鋼材抗(kang)拉功能(neng)強(qiang)。
具有(you)較大的抗(kang)變(bian)形和(he)抗(kang)沉降才(cai)干,施(shi)工過(guo)程中(zhong)重量(liang)輕(qing)、設備方便快捷、施(shi)工簡潔等許多優點。鋼波(bo)紋(wen)管(guan)按構成材(cai)料可(ke)分為金屬(shu)(shu)波(bo)紋(wen)管(guan)、非金屬(shu)(shu)波(bo)紋(wen)管(guan)兩種;按構造可(ke)分為單(dan)層(ceng)(ceng)和(he)多層(ceng)(ceng)。單(dan)層(ceng)(ceng)波(bo)紋(wen)管(guan)應用較多。多層(ceng)(ceng)波(bo)紋(wen)管(guan)強度高,耐久性(xing)好,應力(li)小(xiao),用在重要的測(ce)量(liang)中(zhong)。
鋼波(bo)紋管(guan)的材料(liao)普(pu)通為(wei)青銅(tong)、黃銅(tong)、不銹鋼、蒙乃爾(er)合金(jin)(jin)和因康鎳爾(er)合金(jin)(jin)等。鋼波(bo)紋管(guan)選用規范化設(she)計方案,出產制作(zuo),設(she)計方案簡易,出產制作(zuo)周期(qi)時(shi)間短;工(gong)(gong)(gong)程(cheng)(cheng)項(xiang)目(mu)具體工(gong)(gong)(gong)程(cheng)(cheng)造價比類(lei)似跨距的橋(qiao),洞(dong)低(di);工(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)短工(gong)(gong)(gong)期(qi),要(yao)害為(wei)組裝工(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong);金(jin)(jin)屬(shu)材料(liao)波(bo)紋管(guan)替(ti)代混凝土結構展(zhan)開洞(dong)工(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)。
不管從工程施工周期時間(jian),工程施工工程造價,環境(jing)保(bao)護(hu)實際意(yi)義(yi)等(deng)層(ceng)面(mian)都是(shi)有其不能類比的優勢。鋼波(bo)紋(wen)管有益于(yu)改善軟(ruan)基(ji)處理(li),膨(peng)脹土,濕陷(xian)性(xing)等(deng)共(gong)同路基(ji)結構物處的不勻稱地基(ji)沉(chen)降(jiang)難題。
提升了道路服務項目特性,降低了工后保養成本費;降低了混凝土,塊塊石或砂礫石,砂等的使用量,有益于環境保護;沿海地區地表水多含有不一樣水平的腐蝕,別的山嶺重丘地域土層水流湍急,周期性降水沖刷比較嚴重。//hanihanbj.com/
