鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)(wen)涵(han)(han)(han)(han)管(guan)(guan)價格請咨詢衡水浩威新材料有限公(gong)(gong)司(si),24小時(shi)服務(wu)專線(xian):。鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)(wen)涵(han)(han)(han)(han)管(guan)(guan)也叫波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)(han),是(shi)指鋪埋(mai)在公(gong)(gong)路(lu)、鐵路(lu)路(lu)下的涵(han)(han)(han)(han)洞用的螺紋(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan),它(ta)是(shi)由(you)波(bo)(bo)(bo)形(xing)(xing)鋼(gang)(gang)板卷制成(cheng)或用波(bo)(bo)(bo)形(xing)(xing)鋼(gang)(gang)片組(zu)拼(pin)成(cheng)的圓形(xing)(xing)鋼(gang)(gang)結(jie)構(gou)管(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)(han)的波(bo)(bo)(bo)紋(wen)(wen)結(jie)構(gou)可使涵(han)(han)(han)(han)洞路(lu)面(mian)受力合理,荷(he)載分(fen)布均勻(yun),并具有一定的抗(kang)變形(xing)(xing)能(neng)(neng)力,能(neng)(neng)解決北方(fang)寒(han)冷地(di)區(霜(shuang)凍)對橋梁和管(guan)(guan)涵(han)(han)(han)(han)砼(tong)結(jie)構(gou)的破壞問題;使路(lu)表面(mian)沒有伸(shen)縮縫,提高(gao)行車(che)舒適性;有利于改善(shan)軟(ruan)土(tu)(tu)地(di)基結(jie)構(gou)與路(lu)堤交(jiao)界處的“錯臺”現(xian)象(xiang),提高(gao)行車(che)安全性。波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)(han)的工(gong)后營運(yun)、養護成(cheng)本低,工(gong)程實際造(zao)價也低于同類(lei)跨徑(jing)的橋梁、涵(han)(han)(han)(han)洞。鋼(gang)(gang)波(bo)(bo)(bo)紋(wen)(wen)涵(han)(han)(han)(han)管(guan)(guan)進出口也可按照邊坡比例做成(cheng)斜(xie)口,加工(gong)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)徑(jing)范(fan)圍0.5~8 m,管(guan)(guan)壁厚(hou)度為3 mm~7 mm,能(neng)(neng)夠(gou)滿足填土(tu)(tu)0.5 ~40 m厚(hou)的需要。
鋼波紋涵管的特點:
(1)鋼波紋管涵結構(gou)強度高,勢鋼筋混凝土的(de)1-3倍;對地基承載能力、平(ping)整度要求較(jiao)低(di),工(gong)程實際造價比同類跨徑的(de)橋(qiao)、涵洞相(xiang)近或較(jiao)低(di)。
(2)運營壽命(ming)長,可達100多年(nian)。
(3)施工(gong)周(zhou)期短,工(gong)廠集中化生(sheng)產,生(sheng)產不受(shou)環境(jing)影響(xiang),有(you)利(li)降低(di)成(cheng)本、控(kong)制(zhi)質量。
(4)重量輕(qing)、施工便捷;現場(chang)安(an)裝(zhuang)方便,不需使用大型設(she)備(bei)。
(5)解決北方(fang)寒(han)冷地區(霜凍(dong))對(dui)橋梁和管涵砼結構的破(po)壞問題。
(6)減少或根本(ben)舍棄了常規(gui)建(jian)材,如水泥、黃砂、石子(zi)、木材的(de)使(shi)用,環保(bao)意義深遠。
(7)結構(gou)受(shou)力(li)情況合理,荷載分(fen)布(bu)均勻,并有一定的抗變形能力(li)。
(8)一年四(si)季(ji)可(ke)施(shi)工,施(shi)工不受季(ji)節影響(xiang)。
