鋼波紋涵管也叫波(bo)紋(wen)管(guan)(guan)(guan)涵(han),是(shi)指(zhi)鋪埋在公(gong)路(lu)、鐵(tie)路(lu)路(lu)下的(de)(de)涵(han)洞(dong)用的(de)(de)螺紋(wen)波(bo)紋(wen)管(guan)(guan)(guan),它是(shi)由波(bo)形鋼(gang)板(ban)卷制成或用波(bo)形鋼(gang)片組拼成的(de)(de)圓形鋼(gang)結(jie)構(gou)(gou)管(guan)(guan)(guan)。金屬波(bo)紋(wen)管(guan)(guan)(guan)涵(han)的(de)(de)波(bo)紋(wen)結(jie)構(gou)(gou)可使(shi)涵(han)洞(dong)路(lu)面(mian)(mian)受力合理,荷載分(fen)布均(jun)勻(yun),并具有一定的(de)(de)抗(kang)變(bian)形能(neng)(neng)(neng)力,能(neng)(neng)(neng)解決北方寒冷地(di)區(qu)(霜凍)對橋(qiao)梁和管(guan)(guan)(guan)涵(han)砼結(jie)構(gou)(gou)的(de)(de)破壞問題(ti);使(shi)路(lu)表面(mian)(mian)沒(mei)有伸縮縫(feng),提(ti)(ti)高行(xing)車舒(shu)適性;有利于改善軟土(tu)地(di)基結(jie)構(gou)(gou)與路(lu)堤(di)交界處的(de)(de)“錯臺(tai)”現象,提(ti)(ti)高行(xing)車安(an)全(quan)性。波(bo)紋(wen)管(guan)(guan)(guan)涵(han)的(de)(de)工(gong)后營運、養護(hu)成本低,工(gong)程實際(ji)造價也低于同類跨徑(jing)的(de)(de)橋(qiao)梁、涵(han)洞(dong)。鋼(gang)波(bo)紋(wen)涵(han)管(guan)(guan)(guan)進出口也可按照邊(bian)坡比例做成斜(xie)口,加工(gong)波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑(jing)范圍0.5~8 m,管(guan)(guan)(guan)壁厚度(du)為3 mm~7 mm,能(neng)(neng)(neng)夠滿足填(tian)土(tu)0.5 ~40 m厚的(de)(de)需要。
