鋼波紋涵管也(ye)叫波(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han),是(shi)指鋪埋在公路(lu)、鐵路(lu)路(lu)下的(de)(de)(de)涵(han)洞用的(de)(de)(de)螺紋(wen)波(bo)紋(wen)管(guan)(guan)(guan)(guan),它是(shi)由波(bo)形(xing)鋼(gang)板卷制(zhi)成或用波(bo)形(xing)鋼(gang)片組拼成的(de)(de)(de)圓形(xing)鋼(gang)結構(gou)管(guan)(guan)(guan)(guan)。金屬波(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)的(de)(de)(de)波(bo)紋(wen)結構(gou)可使涵(han)洞路(lu)面(mian)受力合理,荷載(zai)分(fen)布均勻,并具有(you)一定(ding)的(de)(de)(de)抗變(bian)形(xing)能(neng)力,能(neng)解決北方寒(han)冷地區(霜凍)對橋梁和管(guan)(guan)(guan)(guan)涵(han)砼結構(gou)的(de)(de)(de)破壞問題;使路(lu)表(biao)面(mian)沒有(you)伸縮(suo)縫(feng),提高行(xing)(xing)車(che)舒適性;有(you)利于改善(shan)軟土地基結構(gou)與路(lu)堤交界處的(de)(de)(de)“錯臺(tai)”現象,提高行(xing)(xing)車(che)安全性。波(bo)紋(wen)管(guan)(guan)(guan)(guan)涵(han)的(de)(de)(de)工后營運、養護成本低,工程實際造價(jia)也(ye)低于同類跨徑的(de)(de)(de)橋梁、涵(han)洞。鋼(gang)波(bo)紋(wen)涵(han)管(guan)(guan)(guan)(guan)進(jin)出口也(ye)可按照邊坡比例做(zuo)成斜口,加工波(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)(guan)(guan)壁厚度為3 mm~7 mm,能(neng)夠(gou)滿(man)足填土0.5 ~40 m厚的(de)(de)(de)需要。
