鋼波紋管從材(cai)料與結構和功能(neng)的(de)本質關系上(shang)分析,選用(yong)柔性(xing)高(gao)強(qiang)度的(de)鋼波紋管洞(dong)因(yin)為軸向波紋的(de)存(cun)在,使其具有受力特(te)征,軸向和徑(jing)向同時分布因(yin)荷(he)載引(yin)起的(de)應(ying)力應(ying)變,可以更大程度上(shang)渙散荷(he)載的(de)應(ying)力會集,更好地發(fa)揮鋼結構的(de)優(you)勢。
鋼波紋管經濟耐用的原因無人問津
鋼波紋(wen)管具(ju)有施工(gong)(gong)工(gong)(gong)期(qi)短、重量輕、安(an)裝方便、耐久(jiu)性能好、工(gong)(gong)程造價低、抗變形能力強、減少維護(hu)費用成(cheng)本等優(you)點。鋼波紋(wen)管是(shi)一種(zhong)柔性構造,波紋(wen)管在構造上(shang)具(ju)有橫向抵(di)償位移(yi)特性,可充(chong)分發揮鋼材抗拉功能強。
具有較(jiao)(jiao)大的抗(kang)變形和抗(kang)沉降(jiang)才干,施工(gong)(gong)過程中(zhong)重量(liang)輕、設備方便快捷(jie)、施工(gong)(gong)簡潔等許(xu)多(duo)優點。鋼波(bo)紋管按(an)構(gou)成材料可分(fen)為(wei)金屬波(bo)紋管、非金屬波(bo)紋管兩種;按(an)構(gou)造可分(fen)為(wei)單層(ceng)和多(duo)層(ceng)。單層(ceng)波(bo)紋管應用(yong)較(jiao)(jiao)多(duo)。多(duo)層(ceng)波(bo)紋管強(qiang)度高,耐久(jiu)性好(hao),應力(li)小,用(yong)在(zai)重要的測量(liang)中(zhong)。
鋼(gang)(gang)波紋(wen)管(guan)(guan)的材料普(pu)通(tong)為青銅(tong)(tong)、黃銅(tong)(tong)、不銹(xiu)鋼(gang)(gang)、蒙乃爾(er)(er)合金和因康鎳爾(er)(er)合金等。鋼(gang)(gang)波紋(wen)管(guan)(guan)選用規范化設計方(fang)案,出(chu)產制(zhi)作,設計方(fang)案簡易,出(chu)產制(zhi)作周期(qi)時間短;工(gong)(gong)程項目具體工(gong)(gong)程造價比(bi)類似跨距的橋,洞(dong)低;工(gong)(gong)程施工(gong)(gong)短工(gong)(gong)期(qi),要害為組裝工(gong)(gong)程施工(gong)(gong);金屬材料波紋(wen)管(guan)(guan)替代混凝土結構展開洞(dong)工(gong)(gong)程施工(gong)(gong)。
不(bu)(bu)(bu)管(guan)從工(gong)程(cheng)施(shi)工(gong)周期時間(jian),工(gong)程(cheng)施(shi)工(gong)工(gong)程(cheng)造價(jia),環境(jing)保護實際意(yi)義等層面(mian)都是有其不(bu)(bu)(bu)能類(lei)比的(de)優(you)勢。鋼(gang)波(bo)紋管(guan)有益(yi)于改善軟(ruan)基處理,膨脹土,濕陷性等共同路基結(jie)構(gou)物處的(de)不(bu)(bu)(bu)勻稱地(di)基沉降難題。
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/
