拼裝鋼波紋管

在公路(lu)施(shi)工中，應用(yong)鋼波紋(wen)管(guan)涵代替鋼筋混凝土(tu)進(jin)行涵洞(dong)施(shi)工的歷史已經有(you)100多年了。1896年，美(mei)國(guo)(guo)率提高前輩行鋼波紋(wen)管(guan)涵通道、涵管(guan)的可行性研究(jiu)。其后，在美(mei)國(guo)(guo)、加(jia)拿大、澳大利亞等國(guo)(guo)的公路(lu)建設(she)(she)中，均采用(yong)了鋼波紋(wen)管(guan)涵進(jin)行涵洞(dong)的施(shi)工。1990年，日本高速(su)公路(lu)設(she)(she)計，規范制(zhi)定了鋼波紋(wen)管(guan)涵設(she)(she)計技術規范。
