鋼波紋(wen)涵(han)(han)(han)(han)(han)管的開展在咱們高(gao)速公(gong)路(lu)建設過程(cheng)中，涵(han)(han)(han)(han)(han)洞是(shi)一種常(chang)見的結構(gou)(gou)也是(shi)一種十分重要的結構(gou)(gou)，涵(han)(han)(han)(han)(han)洞結構(gou)(gou)一直選用箱涵(han)(han)(han)(han)(han)、蓋板涵(han)(han)(han)(han)(han)、圓(yuan)管涵(han)(han)(han)(han)(han)、拱涵(han)(han)(han)(han)(han)等幾種型式，涵(han)(han)(han)(han)(han)洞在施(shi)工中存在規劃(hua)繁瑣(suo)，施(shi)工時間周期(qi)長，涵(han)(han)(han)(han)(han)洞的孔徑周期(qi)小容易呈(cheng)現沉降和跳車等問題。

鋼(gang)波(bo)紋涵管(guan)的資料主要(yao)(yao)是(shi)由鋼(gang)波(bo)紋板(ban)(ban)(ban)材和(he)強度(du)螺栓(shuan)銜(xian)接(jie)組成的，其間鋼(gang)質(zhi)波(bo)紋板(ban)(ban)(ban)材選(xuan)用(yong)國內遍及運用(yong)的A3或Q235-A熱軋(ya)鋼(gang)板(ban)(ban)(ban)，鋼(gang)板(ban)(ban)(ban)的理化目標要(yao)(yao)求達到GB700的有關要(yao)(yao)求。板(ban)(ban)(ban)的尺寸和(he)厚度(du)為便于板(ban)(ban)(ban)的加工(gong)制造，結構(gou)的裝置銜(xian)接(jie)，進步板(ban)(ban)(ban)的制造精度(du)，板(ban)(ban)(ban)材的尺寸宜適(shi)應不同管(guan)徑的需(xu)求，以形成系(xi)列(lie)化

鋼波紋管

鋼波(bo)(bo)紋涵管因(yin)其一(yi)同(tong)的(de)結構(gou)，軸(zhou)(zhou)向波(bo)(bo)紋的(de)結構(gou)使得它具有徑向剛度大(da)、軸(zhou)(zhou)向柔性大(da)的(de)特征，然后有了抗彎抗裂(lie)功能(neng)(neng)，能(neng)(neng)很(hen)好地(di)習氣地(di)基的(de)變形。而混凝土結構(gou)往往會由(you)于嚴寒導(dao)致材料變脆，導(dao)致原(yuan)有涵洞呈現(xian)開(kai)裂(lie)破碎情(qing)況。施工便捷，能(neng)(neng)削減對凍(dong)土層(ceng)的(de)影響，削減對石(shi)材的(de)開(kai)采，避免(mian)山體損壞，更加環保。

公(gong)(gong)路(lu)工(gong)程(cheng)的涵(han)洞一般(ban)選用金(jin)屬(shu)(shu)筋混凝土制(zhi)作(zuo)。現選用金(jin)屬(shu)(shu)鋼波(bo)紋涵(han)管(guan)(guan)替代金(jin)屬(shu)(shu)筋混凝土進(jin)行(xing)涵(han)洞施(shi)(shi)工(gong)在(zai)國內時一項(xiang)新技術，金(jin)屬(shu)(shu)鋼波(bo)紋涵(han)管(guan)(guan)以其功能穩定、裝置便利(li)、有利(li)環(huan)保(bao)、造價(jia)低等優點迅速在(zai)公(gong)(gong)路(lu)施(shi)(shi)工(gong)中替代了金(jin)屬(shu)(shu)筋混凝土施(shi)(shi)工(gong)的涵(han)洞，發展前景十分(fen)寬廣。
