    摘要: A method is provided which facilitates the nesting of multiple concentric pipes within an existing pipe. The front end of the outer pipe (21) of the nested pipes (2) is sealed off and an auxiliary pipe (3) is joined so as to be detachable to the tail end (e) of said outer pipe (21). A thrusting device (4) is mounted onto said auxiliary pipe (3) and the nested pipes (2) are filled with a filler fluid (28). As the thrusting device (4) exerts pressure on the filler fluid (28), the nested pipes (2) are forced into the existing pipe (1).
