＜産業上の利用分野＞
本考案はコンクリート管のソケツト部に後付け
でカラーを嵌着したカラー付推進管に関するもの
である。[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a propulsion tube with a collar in which a collar is retrofitted to the socket of a concrete tube.
＜従来の技術＞
従来のこの種のソケツト部にカラーを嵌着して

147479号公報に示す如き技術が公知である。<Prior art> A conventional propulsion tube with a collar constructed by fitting a collar into a socket of this type was developed in 1983.
A technique as shown in Japanese Patent No. 147479 is known.
この公知技術はコンクリート管のソケツト部に
リング凹溝を穿設すると共にこのリング凹溝内に
シール材を充填し、更にこのソケツト部に筒状カ
ラーを嵌着して構成したものである。 This known technique is constructed by drilling a ring groove in the socket of a concrete pipe, filling the ring groove with a sealing material, and fitting a cylindrical collar into the socket.

しまう等の問題があつた。 However, in the latter case, the ring protrusions on the collar and the elastic sealing material on the socket are not strongly and deeply engaged, so the water stoppage is not sufficient and the collar easily falls off from the socket when external force is applied. There were problems with storage etc.
本考案は従来のこれ等の問題点に鑑み開発され
