Description of the Related Art When a pipeline such as a sewer pipe buried underground is deteriorated, a pipe lining for repairing the pipeline by lining the inner peripheral surface thereof without excavating the pipeline. A construction method has been proposed and is already in practical use. In this pipe lining method, a pipe lining material obtained by impregnating a curable resin into a tubular resin adsorbent whose outer surface is coated with a highly airtight film is inserted while being inverted into a pipe by fluid pressure, and The pipe lining material is pressed against the inner peripheral surface of the pipe line, and while maintaining that state, the pipe lining material is heated or the like to cure the curable resin impregnated in the pipe lining material. This is a method of repairing the pipeline by lining the inner peripheral surface of the road.

とすることによってなされている。The thickness of the pipe lining material used in such a pipe lining method is adjusted in order to secure necessary strength, and the adjustment of the thickness is generally performed by a plurality of non-woven fabrics. This is achieved by stacking tubular resin adsorbents to form a multilayer structure.

た。For example, when a pipe lining is made of a two-layer tubular resin adsorbent in order to secure a required thickness of the pipe lining, first, a resin adsorbent made of a strip-shaped nonwoven fabric is rolled and both ends thereof are formed. To form a first layer of the tubular resin adsorbent, and another belt-shaped resin adsorbent is rolled up so as to wrap the first layer of the tubular resin adsorbent from the outside, and both ends thereof are joined. After forming a two-layer tubular resin adsorbent and coating the outer surface of the inner and outer two-layer tubular resin adsorbent with a plastic film, impregnating the uncured liquid curable resin into the tubular resin adsorbent of each layer is desirable. A method of manufacturing a pipe lining material having a plate thickness of?

A and 2A are mounted on a roller conveyer 20 so as to be movable substantially horizontally, and the inside thereof is evacuated by a vacuum pump 21. Then, the uncured liquid curable resin 22 injected into the tubular resin adsorbents 1A and 2A is evacuated and sequentially impregnated into the tubular resin adsorbents 1A and 2A.

い。Incidentally, in the impregnation work of the curable resin 22 into the tubular resin adsorbents 1A, 2A having a multilayer structure as shown in FIG. 13, the curability of the tubular resin adsorbents 1A, 2A is reduced. In the non-impregnated portion A in which the resin 22 is not impregnated, there is no relative displacement between the two tubular resin adsorbents 1A and 2A because they are in close contact with each other due to the vacuum.

う問題があった。However, in the impregnated portion B where the curable resin 22 has already been impregnated, the vacuum resin does not act, so that the tubular resin adsorbents 1A and 2A do not adhere to each other.
13A and 2A are pulled to the left in FIG. 13 on the roller conveyor 20, while the curable resin 22 is pulled by the vacuum pump 21 inside the tubular resin adsorbents 1A and 2A in the opposite direction (FIG. 13). Flow to the right), so the tubular resin adsorbent 1A, 2A
Large deviation occurs in the length direction between the inner and outer tubular resin adsorbents 1A and 2A, and the inner tubular resin adsorbent 2A is bent within the outer tubular resin adsorbent 1A. However, there is a problem that swelling occurs in the middle of the pipe lining material.

In this case, it was impossible to heat weld both tubular resin adsorbents. In particular, when the thickness of the tubular resin adsorbent is small, the tubular resin adsorbent may be melted by heat at the time of heat welding, resulting in a hole.
