Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a manufacturing method of a lining pipe in which an existing lining such as a sewer pipe, a water pipe and a gas pipe is formed with a lining layer on the inner surface of the tub, and more specifically, a belt-like shape made of a long plate-like body. The present invention relates to a lining construction device in a pipe rod in which a tubular body formed by winding a member in a spiral shape, a so-called lining pipe, is arranged in the pipe rod.
[0002]
[Prior art]
The present applicant continuously supplies a long band-like member having joints formed on both side edges in a deformed cross-section tube, and spirally winds the members to engage each other. A lining construction apparatus for additionally forming a tubular body formed in this way, which is composed of a molding frame, a guide roller, a joining mechanism portion, and a restriction frame, has been proposed (Japanese Patent Laid-Open No. 8-261363).
