鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)價(jia)格請咨詢衡水浩威新材料有(you)限公司(si),24小(xiao)時服務(wu)專線(xian):。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)也(ye)叫(jiao)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han),是(shi)指鋪埋在(zai)公路、鐵路路下的涵(han)洞用(yong)的螺紋(wen)(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan),它是(shi)由波(bo)(bo)(bo)形鋼(gang)板卷制成(cheng)或用(yong)波(bo)(bo)(bo)形鋼(gang)片(pian)組拼成(cheng)的圓形鋼(gang)結(jie)構(gou)管(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)的波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)結(jie)構(gou)可使(shi)涵(han)洞路面(mian)受力(li)合理,荷載分布均勻,并具(ju)有(you)一(yi)定的抗(kang)變形能力(li),能解(jie)決北方寒(han)冷(leng)地(di)區(霜凍)對橋梁和(he)管(guan)涵(han)砼結(jie)構(gou)的破(po)壞問題;使(shi)路表面(mian)沒(mei)有(you)伸(shen)縮縫,提高行車(che)(che)舒(shu)適(shi)性;有(you)利于改(gai)善軟土地(di)基結(jie)構(gou)與路堤交(jiao)界處的“錯臺”現象,提高行車(che)(che)安全(quan)性。波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)的工后營(ying)運、養護成(cheng)本低(di),工程(cheng)實際造價(jia)也(ye)低(di)于同類跨(kua)徑的橋梁、涵(han)洞。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)進出口也(ye)可按照(zhao)邊坡(po)比例做成(cheng)斜口,加工波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)管(guan)徑范圍0.5~8 m,管(guan)壁厚度為3 mm~7 mm,能夠滿足填土0.5 ~40 m厚的需(xu)要(yao)。
鋼波紋涵管的特點:
(1)鋼波紋(wen)管涵(han)結構(gou)強度(du)高,勢鋼筋(jin)混凝土的1-3倍;對地基承載能力(li)、平整度(du)要求較(jiao)低(di),工程實際造價比同(tong)類跨徑的橋、涵(han)洞相近或較(jiao)低(di)。
(2)運營壽(shou)命長,可(ke)達100多年。
(3)施工(gong)周(zhou)期短,工(gong)廠集中化生(sheng)產(chan),生(sheng)產(chan)不(bu)受環境影(ying)響,有利(li)降低成(cheng)本、控制質量。
(4)重量(liang)輕、施工便(bian)捷;現(xian)場安裝(zhuang)方便(bian),不需使用(yong)大型(xing)設備。
(5)解決(jue)北方寒冷地區(霜(shuang)凍)對橋梁和管涵(han)砼結構的破壞問題。
(6)減少(shao)或(huo)根(gen)本舍棄了常規(gui)建(jian)材(cai),如水泥、黃砂、石子、木(mu)材(cai)的使(shi)用,環保意義深遠。
(7)結構受力(li)情況合理,荷載分布均(jun)勻,并有一(yi)定的抗(kang)變形能力(li)。
(8)一年(nian)四季可施工(gong),施工(gong)不受季節影響。
