鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)涵(han)(han)管(guan)(guan)價(jia)格請咨(zi)詢衡水浩(hao)威新材料有限公(gong)司(si),24小時服務專線:。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)涵(han)(han)管(guan)(guan)也叫波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han),是指鋪埋在公(gong)路(lu)(lu)、鐵路(lu)(lu)路(lu)(lu)下(xia)的(de)(de)(de)涵(han)(han)洞用的(de)(de)(de)螺紋(wen)(wen)(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan),它是由(you)波(bo)(bo)(bo)形(xing)鋼(gang)板卷制成(cheng)或用波(bo)(bo)(bo)形(xing)鋼(gang)片組(zu)拼成(cheng)的(de)(de)(de)圓形(xing)鋼(gang)結(jie)構(gou)管(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)的(de)(de)(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)結(jie)構(gou)可使涵(han)(han)洞路(lu)(lu)面(mian)受力(li)合理,荷載分(fen)布(bu)均勻,并(bing)具有一定(ding)的(de)(de)(de)抗變形(xing)能(neng)力(li),能(neng)解決北方寒冷地(di)區(霜凍)對橋梁和管(guan)(guan)涵(han)(han)砼結(jie)構(gou)的(de)(de)(de)破壞問題;使路(lu)(lu)表面(mian)沒有伸(shen)縮縫,提高(gao)行(xing)車舒適性;有利于改善軟土(tu)地(di)基結(jie)構(gou)與路(lu)(lu)堤交界處的(de)(de)(de)“錯(cuo)臺(tai)”現象,提高(gao)行(xing)車安全性。波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)的(de)(de)(de)工(gong)后營(ying)運、養(yang)護成(cheng)本低,工(gong)程(cheng)實際(ji)造價(jia)也低于同類(lei)跨徑的(de)(de)(de)橋梁、涵(han)(han)洞。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)涵(han)(han)管(guan)(guan)進出口也可按照邊坡比(bi)例(li)做成(cheng)斜口,加工(gong)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)壁(bi)厚度(du)為3 mm~7 mm,能(neng)夠滿足(zu)填土(tu)0.5 ~40 m厚的(de)(de)(de)需要。
鋼波紋涵管的特點:
(1)鋼波紋管涵結構強度高,勢(shi)鋼筋(jin)混凝(ning)土(tu)的(de)1-3倍(bei);對地基(ji)承載能力(li)、平整度要求較低(di)(di),工程實際(ji)造價比同類跨徑的(de)橋、涵洞(dong)相(xiang)近或較低(di)(di)。
(2)運營壽(shou)命(ming)長(chang),可(ke)達(da)100多年(nian)。
(3)施工(gong)周期短,工(gong)廠(chang)集中化生產(chan),生產(chan)不受環境影(ying)響(xiang),有利降低成本、控制質量。
(4)重量輕、施工便(bian)捷(jie);現場安裝方便(bian),不(bu)需使用大型設備。
(5)解決北方寒冷(leng)地區(qu)(霜(shuang)凍(dong))對橋(qiao)梁和管(guan)涵砼結構的破壞問題。
(6)減少或(huo)根本舍棄(qi)了常規建(jian)材,如水(shui)泥、黃砂、石(shi)子、木材的使用,環保意義深遠(yuan)。
(7)結構(gou)受力情況合理,荷載分(fen)布均勻,并有一定的抗變(bian)形能力。
(8)一年四季可施工(gong)(gong),施工(gong)(gong)不(bu)受季節影響。
