摘要：
A buried pipe laying method of additionally coupling a new pipe with the extreme end of a buried pipe laid underground involves flatly deforming a cylindrical pipe having a pipe length smaller than the inside diameter of the buried pipe, conveying the deformed cylindrical pipe to the extreme end of the buried pipe laid underground through the interior thereof, and then returning the deformed shape of the cylindrical pipe to its original circular shape and coupling it with the extreme end of the buried pipe.
