PROBLEM TO BE SOLVED: To provide a multi-function pipe for jacking and its joint suited to lay a pipeline including an auxiliary pipe for realizing the multi-functional use. ;SOLUTION: This multi-function pipe 11 for jacking has a double pipe consisting of a main pipe 12 and an armoring pipe 13 as a basic construction, an auxiliary pipe 14 is arranged between the main pipe 12 and the armoring pipe 13, as a filler 15 around the pipe, a mortar layer 15a is formed, the auxiliary pipe 14 is arranged simply, definitely and as one united body. In this way, the multi-function pipe 11c for jacking is jointed by inserting a socket 21 for the posterior multi-function pipe 11c for propulsion to the socket 21 of the anterior multi-function pipe 1c for propulsion without using welding for jointing on the job site, at the same time, the auxiliary pipe 14 is jointed and a pipeline including the auxiliary pipe is installed.;COPYRIGHT: (C)2001,JPO
