鋼波紋涵管的特點:
(1)鋼波(bo)紋管涵(han)結構強度(du)高,勢鋼筋混凝土(tu)的(de)1-3倍;對(dui)地(di)基承載能(neng)力、平整度(du)要求(qiu)較(jiao)(jiao)低(di),工程實(shi)際造價(jia)比同類跨徑的(de)橋(qiao)、涵(han)洞相近或較(jiao)(jiao)低(di)。
(2)運營壽命長(chang),可(ke)達100多年(nian)。
(3)施工(gong)周(zhou)期(qi)短,工(gong)廠集中化生產,生產不受環境(jing)影響,有利(li)降低(di)成本、控制質(zhi)量。
(4)重量輕、施工便(bian)(bian)捷;現場安裝(zhuang)方(fang)便(bian)(bian),不需使用大型設備。
(5)解(jie)決北方(fang)寒冷地區(霜凍(dong))對橋梁和管涵砼結構的破壞問(wen)題。
(6)減少或根本(ben)舍棄了常(chang)規(gui)建材,如水泥、黃砂、石子(zi)、木(mu)材的使用,環保(bao)意(yi)義深遠。
(7)結構受(shou)力(li)情況合理,荷載分(fen)布均(jun)勻(yun),并(bing)有(you)一定的(de)抗變形能力(li)。
(8)一年四季可施工(gong),施工(gong)不受(shou)季節影響。
鋼波(bo)(bo)(bo)紋(wen)涵(han)管(guan)(guan)(guan)也(ye)叫波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han),是(shi)(shi)指鋪埋在公路(lu)、鐵(tie)路(lu)路(lu)下的(de)涵(han)洞(dong)用(yong)的(de)螺紋(wen)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan),它是(shi)(shi)由波(bo)(bo)(bo)形鋼板卷制(zhi)成(cheng)或用(yong)波(bo)(bo)(bo)形鋼片(pian)組拼(pin)成(cheng)的(de)圓形鋼結構(gou)管(guan)(guan)(guan)。金屬(shu)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)的(de)波(bo)(bo)(bo)紋(wen)結構(gou)可使涵(han)洞(dong)路(lu)面受力合(he)理,荷(he)載分布均勻,并具(ju)有一定的(de)抗變形能(neng)力,能(neng)解決(jue)北方寒冷地(di)(di)區(霜凍)對橋(qiao)梁(liang)和管(guan)(guan)(guan)涵(han)砼(tong)結構(gou)的(de)破壞問題;使路(lu)表(biao)面沒(mei)有伸縮縫(feng),提(ti)高行(xing)車舒(shu)適性;有利于改(gai)善軟土(tu)地(di)(di)基結構(gou)與路(lu)堤交(jiao)界處的(de)“錯臺(tai)”現象,提(ti)高行(xing)車安全性。波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)的(de)工(gong)(gong)后(hou)營運、養護成(cheng)本低,工(gong)(gong)程實際造(zao)價也(ye)低于同類(lei)跨徑的(de)橋(qiao)梁(liang)、涵(han)洞(dong)。鋼波(bo)(bo)(bo)紋(wen)涵(han)管(guan)(guan)(guan)進出口也(ye)可按(an)照邊坡比例(li)做成(cheng)斜(xie)口,加工(gong)(gong)波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑范圍(wei)0.5~8 m,管(guan)(guan)(guan)壁厚度為3 mm~7 mm,能(neng)夠滿足填土(tu)0.5 ~40 m厚的(de)需要(yao)。
