Proposed a lining method and its equipment for irregular cross section pipes. That is, in the deformed section pipe, the joining mechanism is attached to a flexible frame that follows the deformed section, that is, the rectangular section, and a strip-shaped body made of a long plate and having a plastic deformation function is spirally formed. The tubular body is manufactured by wrapping it around and engaging the side edge portions of the strip-shaped bodies adjacent to each other, and lining the inner peripheral surface of the duct with the tubular body. According to this prior art, a lining pipe having a rectangular cross section can be automatically manufactured,
Since the lining pipe is additionally formed by the newly supplied strip-shaped member in front of the rectangular running pipe to be manufactured, it is possible to achieve lengthening and is epoch-making.
Then, following the insertion installation process of this lining pipe,
Cement milk is filled in the gap between the existing pipe and the lining pipe as a material for closing the gap. Due to the filling of the cement milk, the volume density of the lining pipe is relatively small and the floating phenomenon occurs, and as a countermeasure, a means such as installation of a floating prevention mat or loading of heavy objects into the lining pipe is used. Will be taken. Furthermore, as the filling pressure of cement milk increases, the deformation effect on the lining pipe is added, which is harmful. As a countermeasure, at present, the thickness of the lining pipe and thus the plate thickness of the strip-shaped member are increased to increase the rigidity, but this is uneconomical in terms of material cost and construction efficiency.

る。According to the lining pipe supporting and retaining apparatus of the present invention, the deformation of the lining pipe due to the injection pressure of the cement milk filled outside the lining pipe is prevented, and therefore the thickness of the lining pipe is reduced. It is possible and can bring great economic benefits. Further, the diameter of the frame is freely expandable, and it is possible to easily cope with changes in the diameter of the lining pipe. It is also effective as a measure to prevent the lining pipe from rising.
