鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)(han),是指(zhi)鋪埋在公路(lu)、鐵路(lu)路(lu)下(xia)的(de)(de)涵(han)(han)(han)(han)(han)洞(dong)(dong)用的(de)(de)螺紋(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)管(guan),它是由波(bo)(bo)(bo)形(xing)鋼(gang)板(ban)卷制(zhi)成或用波(bo)(bo)(bo)形(xing)鋼(gang)片(pian)組拼成的(de)(de)圓形(xing)鋼(gang)結(jie)構管(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)(han)的(de)(de)波(bo)(bo)(bo)紋(wen)(wen)結(jie)構可(ke)(ke)使(shi)涵(han)(han)(han)(han)(han)洞(dong)(dong)路(lu)面受力(li)合理(li),荷載分(fen)布(bu)均勻,并(bing)具有(you)一定的(de)(de)抗變(bian)形(xing)能力(li),能解決(jue)北方寒冷(leng)地區(霜凍)對橋(qiao)(qiao)梁(liang)和管(guan)涵(han)(han)(han)(han)(han)砼(tong)結(jie)構的(de)(de)破壞問題;使(shi)路(lu)表面沒有(you)伸縮縫(feng),提高行(xing)車舒適性;有(you)利于(yu)改善軟土(tu)地基結(jie)構與路(lu)堤交(jiao)界處的(de)(de)“錯(cuo)臺(tai)”現象(xiang),提高行(xing)車安全性。波(bo)(bo)(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)(han)的(de)(de)工(gong)后營運、養護成本低,工(gong)程(cheng)實際造(zao)價也低于(yu)同(tong)類(lei)跨(kua)徑(jing)的(de)(de)橋(qiao)(qiao)梁(liang)、涵(han)(han)(han)(han)(han)洞(dong)(dong)。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)涵(han)(han)(han)(han)(han)管(guan)進出口(kou)也可(ke)(ke)按照邊坡比(bi)例做成斜口(kou),加工(gong)波(bo)(bo)(bo)紋(wen)(wen)管(guan)管(guan)徑(jing)范圍(wei)0.5~8 m,管(guan)壁厚度為3 mm~7 mm,能夠(gou)滿足填土(tu)0.5 ~40 m厚的(de)(de)需要。
