鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)價格(ge)請咨詢衡水浩威新(xin)材料有(you)限公司(si),24小時(shi)服務專線:。鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)也叫波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han),是(shi)指鋪埋在公路(lu)、鐵路(lu)路(lu)下的(de)涵(han)(han)(han)洞(dong)用的(de)螺紋(wen)(wen)(wen)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan),它是(shi)由波(bo)(bo)形鋼(gang)板卷制成(cheng)(cheng)或用波(bo)(bo)形鋼(gang)片組拼成(cheng)(cheng)的(de)圓(yuan)形鋼(gang)結(jie)構管(guan)(guan)(guan)(guan)。金(jin)屬波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)的(de)波(bo)(bo)紋(wen)(wen)(wen)結(jie)構可使(shi)涵(han)(han)(han)洞(dong)路(lu)面受力合理,荷(he)載(zai)分(fen)布均勻(yun),并具有(you)一定的(de)抗變(bian)形能力,能解決北方寒(han)冷地區(霜凍)對橋梁和(he)管(guan)(guan)(guan)(guan)涵(han)(han)(han)砼結(jie)構的(de)破壞問(wen)題;使(shi)路(lu)表(biao)面沒有(you)伸縮縫,提(ti)高行(xing)(xing)車舒適性(xing);有(you)利于改善軟土地基結(jie)構與路(lu)堤交界處(chu)的(de)“錯臺”現象,提(ti)高行(xing)(xing)車安全性(xing)。波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)涵(han)(han)(han)的(de)工(gong)(gong)后營(ying)運、養護成(cheng)(cheng)本(ben)低,工(gong)(gong)程實際造價也低于同類跨徑(jing)的(de)橋梁、涵(han)(han)(han)洞(dong)。鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)(guan)進出口(kou)也可按照邊坡比例(li)做成(cheng)(cheng)斜口(kou),加工(gong)(gong)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)徑(jing)范圍0.5~8 m,管(guan)(guan)(guan)(guan)壁厚(hou)度為3 mm~7 mm,能夠滿足填(tian)土0.5 ~40 m厚(hou)的(de)需要。
鋼波紋涵管的特點:
(1)鋼波(bo)紋(wen)管涵(han)結(jie)構(gou)強(qiang)度(du)高(gao),勢鋼筋混凝土的(de)1-3倍(bei);對地基(ji)承載能力、平整度(du)要求較(jiao)低,工(gong)程實際(ji)造價比(bi)同類跨徑的(de)橋、涵(han)洞(dong)相近或較(jiao)低。
(2)運營壽命長,可(ke)達100多年。
(3)施工周期(qi)短,工廠集中化生(sheng)(sheng)產,生(sheng)(sheng)產不受環境影響,有(you)利降低成(cheng)本、控制質量。
(4)重量輕、施工便捷;現場安裝(zhuang)方便,不需使用大型設備。
(5)解決北方(fang)寒冷地區(霜(shuang)凍)對橋梁和管涵砼結構的破壞問(wen)題(ti)。
(6)減(jian)少(shao)或根本(ben)舍(she)棄了常規建材(cai),如水泥、黃砂(sha)、石子、木材(cai)的使用,環保(bao)意義深遠。
(7)結構受力情況合理,荷(he)載分布均勻,并有一定的抗變形能力。
(8)一年四季可施工,施工不受季節影響。
