鋼(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)價(jia)格請咨詢衡水浩(hao)威(wei)新材料(liao)有(you)限公(gong)司,24小(xiao)時(shi)服務專(zhuan)線:。鋼(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)也(ye)叫(jiao)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han),是(shi)指(zhi)鋪埋在公(gong)路、鐵路路下的涵(han)洞(dong)用的螺紋(wen)(wen)(wen)(wen)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan),它(ta)是(shi)由波(bo)(bo)(bo)(bo)(bo)形(xing)(xing)鋼(gang)(gang)板(ban)卷制成或用波(bo)(bo)(bo)(bo)(bo)形(xing)(xing)鋼(gang)(gang)片組拼成的圓形(xing)(xing)鋼(gang)(gang)結(jie)構管(guan)。金屬波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)的波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)結(jie)構可使(shi)涵(han)洞(dong)路面受(shou)力合理,荷載分布均勻,并具有(you)一定(ding)的抗變(bian)形(xing)(xing)能(neng)力,能(neng)解決(jue)北(bei)方寒(han)冷地區(霜凍)對橋梁(liang)和管(guan)涵(han)砼結(jie)構的破(po)壞問(wen)題;使(shi)路表面沒有(you)伸縮縫,提高行車(che)(che)舒適性;有(you)利于改善軟土(tu)地基結(jie)構與路堤交(jiao)界處的“錯臺”現象(xiang),提高行車(che)(che)安全性。波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)涵(han)的工(gong)(gong)后(hou)營運、養護成本低,工(gong)(gong)程實(shi)際造價(jia)也(ye)低于同類跨徑(jing)(jing)的橋梁(liang)、涵(han)洞(dong)。鋼(gang)(gang)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)管(guan)進(jin)出口(kou)也(ye)可按照邊坡比(bi)例做成斜口(kou),加工(gong)(gong)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)管(guan)徑(jing)(jing)范圍0.5~8 m,管(guan)壁厚度(du)為3 mm~7 mm,能(neng)夠滿足(zu)填土(tu)0.5 ~40 m厚的需要。
鋼波紋涵管的特點:
(1)鋼波紋管涵結構強度高,勢(shi)鋼筋混(hun)凝土(tu)的1-3倍;對地基承載能力(li)、平整度要求較低,工程實際造價比同類(lei)跨徑(jing)的橋、涵洞相(xiang)近或(huo)較低。
(2)運(yun)營壽命長,可達100多年(nian)。
(3)施工周期短,工廠集中化生(sheng)產,生(sheng)產不受環(huan)境影響,有利(li)降(jiang)低成本、控(kong)制質量。
(4)重(zhong)量(liang)輕、施(shi)工便捷;現場安裝(zhuang)方便,不需使(shi)用大型設備。
(5)解決北方寒冷地區(霜凍)對橋梁和管(guan)涵砼結構的(de)破(po)壞問題。
(6)減少或根本(ben)舍棄了(le)常規(gui)建材(cai),如(ru)水泥(ni)、黃(huang)砂、石子、木材(cai)的使(shi)用,環保意義深遠。
(7)結(jie)構(gou)受力情況合理(li),荷載分布均勻,并有一定的抗變形(xing)能力。
(8)一(yi)年(nian)四(si)季可施(shi)工,施(shi)工不受季節(jie)影響。
