Description
Foreign application: metal corrugated pipe culvert was born in Britain in 1784, and in 1896 the
United States took it in the feasibility study of corrugated steel culvert and channel, and was first
applied to highway culvert, . In 1923 the American Railway Engineering Association tested the
corrugated channel Illinois central railroad. Since then, corrugated steel culvert products are widelyused in Highway Engineering in USA and Canada, and developed the corresponding technicalstandards of design, manufacture, construction and installation manual. Japan, South Korea andother East Asian countries began to set the corresponding technical specifications of corrugated metalpipe culvert. Since the eighty century to the ninety's, began to be widely used. With the application andrunning around the world for nearly one hundred years, verify the universality of metal corrugated pipeculvert under different conditions. Now, standard and specification of all countries is complete,technology has been very mature, and its service life has been over the design life.
