摘要

The present invention relates to a prefabricated culvert having at least a pair of first and second members in mutual butt contact, wherein the first member and the second member cooperate along a butt contact line to define a predetermined width And a connecting grouting portion formed on the rear grouting groove and interposed between the grouting grooves. Thereby, a prefabricated culvert and its installation method are provided which can be easily assembled and the deformation of the culvert joint can be minimized.
