Problems solved by technology

[0005] However, the liner formed by the former (JP-A-8-261363 Gazette) is difficult to tightly adhere to the inner surface of the pipeline, which will reduce the inner diameter of the pipeline to some extent, and the loss of the section cannot be avoided.
In addition, although the latter technique (JP-A-9-57850) can ensure a liner formed over the entire cross-section of the conduit, it requires a diameter-expanding operation every time, or it is difficult to convey the belt even if it is continuously operated. shaped components, making it difficult to operate
[0006] Moreover, in the above two prior art, from the point of view of increasing strength, after the liner is inserted through a long distance, it is necessary to pour coagulable cement and other masonry fillings between the liner and the conduit. material, but because the gap between the liner and the conduit is too small, not only the perfusion operation is very difficult, but also the reliability after perfusion is very low, especially in the prior art of the latter, in fact, it has to be Abandoning Masonry Fill Jobs

Abstract

In lining work in which a lining pipe R formed by spirally winding a strip-like member 500 consisting of an elongated sheet-form body is left in place inside a tubular culvert P, and a new lining pipe is additionally formed in front of this lining pipe that has been left in place, a lining apparatus S which has a flexible forming frame 1 consisting of link bodies is used. The strip-like member 500 is wound around the forming frame 1 by means of a joining mechanism part 7 attached to the forming frame 1, and a lining pipe R is formed while being forcibly folded inward utilizing the flexibility of the forming frame 1; at the same time, a back-filling material is injected into the inward-folded part. The inward-folded part later returns to its original state. Alternatively, the diameter of a small-diameter lining pipe R formed by winding around the forming frame 201-or 401 is expanded, and lining is performed with the back-filling material injected during this diameter expansion process. As a result of this lining work, a lining pipe R that fills the cross section of the tubular culvert P is formed; at the same time, back-filling work is performed on this long lining pipe.

Description

technical field [0001] The invention relates to a lining construction method and a device for lining the inner surface of the pipelines in the pipelines that have been laid, such as sewer pipes, tap water pipes, and gas pipes. More specifically, it relates to a tubular body called a liner pipe formed by winding a strip-shaped member made of a long plate-shaped body in a spiral shape, and inserting the liner pipe into the duct for lining construction in the duct Lining construction method and device. [0002] In particular, the present invention mainly focuses on lining construction along with pouring of masonry filling materials, but the technical idea of ​​the present invention is not limited thereto. Background technique [0003] In the past, the lining construction method that has been proposed is to use a pipe-making device that can be automatically rotated and propelled in the duct, and form a continuous supply of long-sized strip-shaped members that form joints on bot...
