Proposed a lining construction method and equipment for a cross-section culvert. That is, in the duct with the irregular cross section, the joining mechanism is attached to the flexible frame that follows the irregular cross section, that is, the rectangular cross section, and the belt-like body formed of a long plate and having a plastic deformation function is spirally formed. And a tubular body is manufactured by engaging the side edges of the strips adjacent to each other, and the inner peripheral surface of the conduit is lined with the tubular body. According to this prior art, a lining pipe having a rectangular cross section can be automatically manufactured,
Since the lining tube is additionally formed with a band-shaped member newly supplied in front of the rectangular running tube to be manufactured, the length can be increased, and this is epoch-making.
Then, following this lining tube insertion and installation process,
The gap between the existing pipe and the lining pipe is filled with cement milk as a closing material for the gap. Due to the filling of the cement milk, the volume density of the lining pipe is relatively small, and a floating phenomenon occurs. As a countermeasure against this, installation of a mat for preventing floating, or loading of heavy objects into the lining pipe, etc. Will be taken. Furthermore, as the filling pressure of the cement milk increases, the lining tube is deformed, which is harmful. As a countermeasure, at present, the thickness of the lining pipe and, consequently, the thickness of the band-shaped member are increased to increase rigidity, but it is uneconomical in terms of material cost and construction efficiency.

る。According to the apparatus for supporting a lining pipe of the present invention, the lining pipe is prevented from being deformed due to the injection pressure of the cement milk filled into the outside of the lining pipe, and thus the wall thickness of the lining pipe is reduced. And provide significant economic benefits. Further, the diameter of the frame is freely expandable, so that it can easily cope with a change in the diameter of the lining pipe. It is also effective in preventing the lining pipe from floating.
