鋼波紋涵管——衡水浩(hao)威(wei)新材料有限公司(si)主營產品(pin):鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)、鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)、橋(qiao)梁(liang)鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)、鐵路鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)、公路鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)、鋼制波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)、整裝波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)、拼(pin)裝波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)、鍍鋅(xin)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)、金屬波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)、塑料波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)等。
鋼波紋涵管的特點:
(1)鋼波紋管涵結構強度高,勢鋼筋混凝土的(de)1-3倍(bei);對地基承載能力、平整(zheng)度要求較低,工程實際造價(jia)比同類跨徑的(de)橋、涵洞相(xiang)近(jin)或較低。
(2)運營壽命長,可達100多(duo)年。
(3)施工周(zhou)期短,工廠集中化生(sheng)產,生(sheng)產不受環境影響,有利降低成本、控(kong)制質量。
(4)重量輕、施工便捷(jie);現場安裝方便,不需使用大型設備。
(5)解決(jue)北方寒冷(leng)地區(霜凍(dong))對橋梁(liang)和管涵砼結構(gou)的破壞問題。
(6)減(jian)少(shao)或根(gen)本(ben)舍(she)棄了常規建(jian)材,如(ru)水泥、黃砂(sha)、石(shi)子、木(mu)材的(de)使(shi)用,環保意(yi)義(yi)深遠(yuan)。
(7)結構受力情況合理,荷載(zai)分布(bu)均勻,并有(you)一定的抗變形能(neng)力。
(8)一年四季(ji)可(ke)施(shi)工(gong),施(shi)工(gong)不受季(ji)節影響。
鋼(gang)波(bo)(bo)紋(wen)(wen)涵(han)(han)管(guan)(guan)也叫(jiao)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han),是指鋪埋(mai)在(zai)公路(lu)、鐵路(lu)路(lu)下的涵(han)(han)洞用(yong)的螺紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)(guan),它是由波(bo)(bo)形(xing)鋼(gang)板(ban)卷(juan)制成(cheng)(cheng)或(huo)用(yong)波(bo)(bo)形(xing)鋼(gang)片組(zu)拼成(cheng)(cheng)的圓形(xing)鋼(gang)結(jie)構(gou)管(guan)(guan)。金屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)的波(bo)(bo)紋(wen)(wen)結(jie)構(gou)可使(shi)涵(han)(han)洞路(lu)面受力合理,荷載分(fen)布均勻(yun),并具有(you)一定的抗變形(xing)能(neng)力,能(neng)解決(jue)北方寒冷(leng)地(di)區(霜(shuang)凍)對橋梁和管(guan)(guan)涵(han)(han)砼結(jie)構(gou)的破壞問(wen)題;使(shi)路(lu)表面沒有(you)伸縮縫,提高(gao)(gao)行(xing)車舒(shu)適性;有(you)利(li)于(yu)改(gai)善軟土地(di)基(ji)結(jie)構(gou)與路(lu)堤交界處的“錯臺”現象,提高(gao)(gao)行(xing)車安全(quan)性。波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)的工后營運、養護成(cheng)(cheng)本低,工程實際造(zao)價也低于(yu)同類跨徑的橋梁、涵(han)(han)洞。鋼(gang)波(bo)(bo)紋(wen)(wen)涵(han)(han)管(guan)(guan)進出口也可按(an)照邊坡比例做(zuo)成(cheng)(cheng)斜(xie)口,加(jia)工波(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)徑范圍(wei)0.5~8 m,管(guan)(guan)壁厚(hou)度為(wei)3 mm~7 mm,能(neng)夠滿足填土0.5 ~40 m厚(hou)的需要。
