鋼波紋管從(cong)材料(liao)與結構(gou)和功(gong)能的本質關系上(shang)分析,選用柔(rou)性高強度(du)(du)的鋼波(bo)紋管洞因為軸(zhou)向(xiang)波(bo)紋的存在,使其具有受力特征,軸(zhou)向(xiang)和徑向(xiang)同時分布因荷(he)載(zai)引起的應力應變,可以更大程度(du)(du)上(shang)渙散荷(he)載(zai)的應力會集,更好地發(fa)揮鋼結構(gou)的優(you)勢。
鋼波紋管經濟耐用的原因無人問津
鋼(gang)波(bo)紋管(guan)具(ju)有施工(gong)工(gong)期短、重量輕、安(an)裝方便、耐久性能好、工(gong)程(cheng)造(zao)價低、抗變形能力強(qiang)(qiang)、減少維護(hu)費用成本等(deng)優點。鋼(gang)波(bo)紋管(guan)是(shi)一種(zhong)柔性構造(zao),波(bo)紋管(guan)在構造(zao)上具(ju)有橫向抵償(chang)位移(yi)特(te)性,可充分(fen)發揮(hui)鋼(gang)材(cai)抗拉功能強(qiang)(qiang)。
具有較(jiao)大的(de)抗(kang)變(bian)形和抗(kang)沉降(jiang)才干,施(shi)工(gong)過程中(zhong)重量輕、設備方(fang)便快捷、施(shi)工(gong)簡潔(jie)等許多優點。鋼波(bo)紋(wen)管(guan)(guan)按構(gou)成材料可(ke)分為(wei)金屬(shu)波(bo)紋(wen)管(guan)(guan)、非金屬(shu)波(bo)紋(wen)管(guan)(guan)兩種;按構(gou)造可(ke)分為(wei)單(dan)層和多層。單(dan)層波(bo)紋(wen)管(guan)(guan)應(ying)用(yong)較(jiao)多。多層波(bo)紋(wen)管(guan)(guan)強度高,耐久性好,應(ying)力(li)小,用(yong)在重要的(de)測量中(zhong)。
鋼(gang)波(bo)(bo)紋(wen)(wen)管的(de)材(cai)料(liao)普通(tong)為青銅(tong)、黃銅(tong)、不銹鋼(gang)、蒙乃爾合金(jin)和因康鎳爾合金(jin)等。鋼(gang)波(bo)(bo)紋(wen)(wen)管選用規范化設計(ji)(ji)方(fang)(fang)案(an)(an),出產制(zhi)作(zuo)(zuo),設計(ji)(ji)方(fang)(fang)案(an)(an)簡易(yi),出產制(zhi)作(zuo)(zuo)周期時間短;工(gong)(gong)(gong)程(cheng)(cheng)(cheng)項(xiang)目具(ju)體工(gong)(gong)(gong)程(cheng)(cheng)(cheng)造價(jia)比類似跨距的(de)橋,洞低;工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施工(gong)(gong)(gong)短工(gong)(gong)(gong)期,要害為組裝工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施工(gong)(gong)(gong);金(jin)屬材(cai)料(liao)波(bo)(bo)紋(wen)(wen)管替代混凝(ning)土(tu)結(jie)構(gou)展開洞工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施工(gong)(gong)(gong)。
不管(guan)(guan)從工(gong)程(cheng)施工(gong)周期(qi)時間,工(gong)程(cheng)施工(gong)工(gong)程(cheng)造價,環境保(bao)護實際意義等層面都是(shi)有其不能類比的(de)優勢(shi)。鋼波紋管(guan)(guan)有益(yi)于改善(shan)軟(ruan)基處理,膨脹土,濕陷性等共同路基結構(gou)物處的(de)不勻稱(cheng)地(di)基沉降(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/
