鋼波紋涵管也叫波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han),是(shi)指鋪埋在公路(lu)(lu)、鐵路(lu)(lu)路(lu)(lu)下的(de)(de)(de)涵(han)洞(dong)(dong)用的(de)(de)(de)螺紋(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan),它是(shi)由波(bo)(bo)(bo)形鋼板卷制成(cheng)或用波(bo)(bo)(bo)形鋼片組拼成(cheng)的(de)(de)(de)圓形鋼結(jie)(jie)構管(guan)(guan)(guan)(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)的(de)(de)(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)結(jie)(jie)構可使(shi)涵(han)洞(dong)(dong)路(lu)(lu)面受(shou)力合理,荷載分布(bu)均(jun)勻,并(bing)具(ju)有一(yi)定的(de)(de)(de)抗變形能力,能解(jie)決北方寒(han)冷地區(霜凍)對橋梁和管(guan)(guan)(guan)(guan)(guan)涵(han)砼結(jie)(jie)構的(de)(de)(de)破(po)壞問(wen)題(ti);使(shi)路(lu)(lu)表面沒有伸縮縫,提高(gao)行(xing)車舒適性(xing);有利于(yu)改(gai)善軟土(tu)地基結(jie)(jie)構與路(lu)(lu)堤交界處的(de)(de)(de)“錯臺(tai)”現象(xiang),提高(gao)行(xing)車安全性(xing)。波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)的(de)(de)(de)工(gong)后營運、養(yang)護成(cheng)本(ben)低,工(gong)程實際造(zao)價也低于(yu)同類跨徑(jing)的(de)(de)(de)橋梁、涵(han)洞(dong)(dong)。鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)涵(han)管(guan)(guan)(guan)(guan)(guan)進出口(kou)也可按(an)照邊(bian)坡比例做(zuo)成(cheng)斜口(kou),加(jia)工(gong)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)徑(jing)范圍0.5~8 m,管(guan)(guan)(guan)(guan)(guan)壁厚(hou)度(du)為(wei)3 mm~7 mm,能夠滿足填(tian)土(tu)0.5 ~40 m厚(hou)的(de)(de)(de)需(xu)要(yao)。
