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 widely used in Highway Engineering in USA and Canada, and developed the corresponding technical standards of design, manufacture, construction and installation manual. Japan, South Korea and other East Asian countries began to set the corresponding technical specifications of corrugated metal pipe culvert. Since the eighty century to the ninety's, began to be widely used. With the application and running around the world for nearly one hundred years, verify the universality of metal corrugated pipe culvert 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.
