鋼(gang)(gang)(gang)(gang)波(bo)(bo)紋(wen)涵管(guan)(guan)(guan)價格請咨詢衡(heng)水浩(hao)威新材料有(you)限公(gong)司,24小時服務專(zhuan)線:。鋼(gang)(gang)(gang)(gang)波(bo)(bo)紋(wen)涵管(guan)(guan)(guan)也(ye)叫波(bo)(bo)紋(wen)管(guan)(guan)(guan)涵,是指鋪埋(mai)在公(gong)路(lu)、鐵路(lu)路(lu)下的(de)(de)涵洞(dong)用的(de)(de)螺紋(wen)波(bo)(bo)紋(wen)管(guan)(guan)(guan),它是由波(bo)(bo)形(xing)鋼(gang)(gang)(gang)(gang)板卷(juan)制成(cheng)(cheng)或用波(bo)(bo)形(xing)鋼(gang)(gang)(gang)(gang)片組拼成(cheng)(cheng)的(de)(de)圓(yuan)形(xing)鋼(gang)(gang)(gang)(gang)結構(gou)管(guan)(guan)(guan)。金屬波(bo)(bo)紋(wen)管(guan)(guan)(guan)涵的(de)(de)波(bo)(bo)紋(wen)結構(gou)可使(shi)涵洞(dong)路(lu)面受力(li)合理,荷載分布(bu)均勻,并具(ju)有(you)一定(ding)的(de)(de)抗變(bian)形(xing)能(neng)力(li),能(neng)解決北方寒冷地(di)區(霜(shuang)凍)對橋梁(liang)和管(guan)(guan)(guan)涵砼結構(gou)的(de)(de)破壞(huai)問(wen)題(ti);使(shi)路(lu)表面沒有(you)伸縮縫,提高行(xing)車舒適性;有(you)利于(yu)改善軟(ruan)土地(di)基結構(gou)與路(lu)堤交界處的(de)(de)“錯臺”現(xian)象,提高行(xing)車安(an)全性。波(bo)(bo)紋(wen)管(guan)(guan)(guan)涵的(de)(de)工(gong)(gong)后(hou)營運、養護成(cheng)(cheng)本低,工(gong)(gong)程實際造價也(ye)低于(yu)同(tong)類跨徑(jing)的(de)(de)橋梁(liang)、涵洞(dong)。鋼(gang)(gang)(gang)(gang)波(bo)(bo)紋(wen)涵管(guan)(guan)(guan)進出(chu)口也(ye)可按照邊(bian)坡(po)比例做(zuo)成(cheng)(cheng)斜口,加工(gong)(gong)波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)徑(jing)范圍(wei)0.5~8 m,管(guan)(guan)(guan)壁厚(hou)度為3 mm~7 mm,能(neng)夠(gou)滿足填土0.5 ~40 m厚(hou)的(de)(de)需要。
鋼波紋涵管的特點:
(1)鋼波紋(wen)管(guan)涵結構強度高,勢鋼筋混(hun)凝土的1-3倍;對地基承載能力、平(ping)整度要求較(jiao)低,工程(cheng)實際造(zao)價(jia)比同類跨徑的橋、涵洞相近(jin)或較(jiao)低。
(2)運營壽命(ming)長(chang),可達100多年。
(3)施工(gong)(gong)周期短,工(gong)(gong)廠集中化生(sheng)產,生(sheng)產不受(shou)環境影響,有利降低(di)成本、控制質(zhi)量。
(4)重(zhong)量輕(qing)、施工便捷(jie);現場安裝方(fang)便,不需使用大型(xing)設(she)備(bei)。
(5)解(jie)決北方(fang)寒(han)冷(leng)地區(霜凍(dong))對橋梁和管涵砼結(jie)構(gou)的破壞(huai)問(wen)題。
(6)減少或根本(ben)舍棄了常(chang)規(gui)建(jian)材(cai)(cai),如水泥、黃砂、石子、木材(cai)(cai)的使用,環保意義深(shen)遠(yuan)。
(7)結構受力情況合理,荷載(zai)分布(bu)均勻,并有一定的抗變形能力。
(8)一年(nian)四季(ji)可施(shi)工,施(shi)工不受季(ji)節影響(xiang)。
