In a small-diameter pipe propulsion machine for burying a pilot pipe 2, a tapered enlarged head 11 with a small diameter side removably connected to the tip of a pilot pipe 2 buried underground is provided, and a large diameter side of this enlarged head 11 is used to carry a buried pipe. 12
At the same time, one end of the buried pipe 12 is fitted, and the other end of the buried pipe 12 is fitted with
A pipe embedding device for a small diameter pipe propulsion machine, which is formed by fitting the expanding head 11 and a pressing means connected by a connecting member 13. (2) The pressing means is composed of a connecting bolt 14 connected to the enlarged head 11 by a connecting member 13, a nut 15 screwed to the connecting bolt 14, and a protective plate 16 locked to the nut 15. The pipe embedding device according to claim 1. (3) The pipe embedding device according to claim 1, wherein the connecting member 13 is formed of a combustible member such as a chain or a wire.
