Claims

[Claims for Utility Model Registration] (1) The end face of the lining layer formed inside the pipe is arranged inward of the pipe axis from the end face of the pipe, and the inner circumferential face exposed from the lining layer of the pipe and ,
An annular protective member made of an elastic body is provided radially inwardly across the end of the lining layer, and a pressing means is provided radially inwardly of the protective member,
An end treatment structure for a pipe lining layer, characterized in that the pressing means presses the protective member across the inner circumferential surface exposed from the pipe lining layer and the end of the lining layer. . (2) The pressing means includes: a pressing member disposed radially inward of the protective member and divided in the circumferential direction; and a displacement means displacing both circumferential ends of the pressing member in a direction away from each other. An end treatment structure for a pipe lining layer according to claim 1, which is characterized in that: (3) The displacement means includes a threaded rod having threads with opposite winding directions, and an inner threaded member that is screwed into each of the threads of the threaded rod, and the threaded rod and the inner threaded member are screwed together. By providing either one of the threaded member at both ends in the circumferential direction of the pressing member to prevent mutual displacement in the separating direction, and rotating the other of the threaded rod and the internal threaded member, The end treatment structure for a pipe lining layer according to claim 2, wherein both ends of the pressing member in the circumferential direction are displaced in directions away from each other.
