鋼(gang)波紋(wen)(wen)管(guan)價(jia)格多少錢(qian)一(yi)米2022年(nian)報價(jia)有變化嗎?鋼(gang)波紋(wen)(wen)涵管(guan)的特點:
(1)鋼波紋管涵(han)結構強度(du)高,勢鋼筋(jin)混凝土的1-3倍;對地基承載能力(li)、平整(zheng)度(du)要求較低(di),工程實際造(zao)價比同類(lei)跨徑的橋、涵(han)洞(dong)相近或較低(di)。
(2)運營壽命長,可達100多年。
(3)施工(gong)周期短,工(gong)廠集中化生產,生產不(bu)受環(huan)境影響,有利降低(di)成(cheng)本、控制(zhi)質(zhi)量。
(4)重量輕、施工便捷(jie);現場(chang)安裝方便,不需使(shi)用大型(xing)設備(bei)。
(5)解決北方寒冷(leng)地區(霜凍)對橋(qiao)梁和管涵砼結(jie)構的破壞(huai)問題。
(6)減少(shao)或根本舍棄了常規(gui)建材(cai),如水泥、黃(huang)砂、石子、木材(cai)的使(shi)用,環保意義深遠(yuan)。
(7)結構受(shou)力(li)情況合理,荷載分(fen)布均(jun)勻,并有一定的抗變形能力(li)。
(8)一(yi)年四季可施工(gong),施工(gong)不受季節影響。
鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)價格多(duo)少錢一(yi)米2022年報價有變化嗎?鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)也叫(jiao)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)(han),是指鋪埋在公路(lu)、鐵路(lu)路(lu)下的(de)(de)(de)涵(han)(han)(han)洞用的(de)(de)(de)螺紋(wen)(wen)(wen)(wen)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan),它是由波(bo)(bo)(bo)形鋼(gang)板卷制成(cheng)(cheng)(cheng)或(huo)用波(bo)(bo)(bo)形鋼(gang)片組拼成(cheng)(cheng)(cheng)的(de)(de)(de)圓形鋼(gang)結構(gou)管(guan)(guan)。金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)(han)的(de)(de)(de)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)結構(gou)可使涵(han)(han)(han)洞路(lu)面(mian)受力合理,荷載分(fen)布(bu)均勻(yun),并具有一(yi)定(ding)的(de)(de)(de)抗變形能(neng)力,能(neng)解決北方寒冷地(di)(di)區(霜凍)對橋(qiao)梁和管(guan)(guan)涵(han)(han)(han)砼(tong)結構(gou)的(de)(de)(de)破(po)壞問題(ti);使路(lu)表(biao)面(mian)沒(mei)有伸縮縫(feng),提高行車舒適性(xing)(xing);有利于改善軟土地(di)(di)基(ji)結構(gou)與路(lu)堤交(jiao)界處的(de)(de)(de)“錯臺”現象,提高行車安全性(xing)(xing)。波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)(han)的(de)(de)(de)工后營運、養護成(cheng)(cheng)(cheng)本低(di),工程(cheng)實際造價也低(di)于同類跨徑的(de)(de)(de)橋(qiao)梁、涵(han)(han)(han)洞。鋼(gang)波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)進出口也可按照(zhao)邊坡比例做成(cheng)(cheng)(cheng)斜口,加工波(bo)(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)徑范圍0.5~8 m,管(guan)(guan)壁厚度(du)為3 mm~7 mm,能(neng)夠滿足填土0.5 ~40 m厚的(de)(de)(de)需要。
