(Patent Document 3) Japanese Unexamined Patent Publication No. 6-262684

      The present invention relates to an improved method for inserting a pipe lining material into an aging sewer pipe.

      As a conventional technique, a method of inserting a pipe lining material into a pipe is disclosed in Japanese Patent Laid-Open Nos. 1-242232, Japanese Patent Laid-Open No. 64-42220, and Japanese Patent Laid-Open No. 6-262684.

      According to the "pipe repair method" shown in Japanese Patent Laid-Open No. 1-242232, one end of a liner and a rope is connected to the distal end of the freeliner before reversing, and the freeliner is inserted into the aging tube by fluid pressure. At the same time, the rope is pulled in the direction of insertion of the free liner, the liner is drawn into the free liner after reversal, and then the other free liner in the liner is reverse inserted by fluid pressure, and the liner is impregnated while maintaining this state. (Iii) A method for repairing a pipeline, characterized in that for curing the cured resin.

      `` Method and apparatus for laying a new pipe inside an existing pipe '' shown in Japanese Unexamined Patent Publication No. 64-42220 is a thermoplastic member having rigidity in which the dimension of the entire cross section is reduced in proportion to the existing pipe. A method of laying a pipe having a new rigidity in the pipe by using a method, comprising: a heating step sufficient to change the thermoplastic member from a normal rigid state to a flexible state, and the existing member in a state in which the thermoplastic member is flexibly reduced in dimensions; Inserting into the pipe, and inflating the thermoplastic member drawn into the pipe in a flexible state, and after cooling, forming a shape-leadable tubular inner pipe having rigidity capable of withstanding hydraulic and earth pressure from the outside. Pipe with new rigidity inside existing pipe A method for laying.

      In addition, the "reversing method of the tube lining material" shown in Japanese Patent Laid-Open No. 6-262684 is a reversal method of the tube lining material into the pipeline, and after the compressed bag supplied with the compressed gas is expanded in the pipeline, A part of the lining material is reversely inserted into the pipeline by pressure, the lining material passes through the sealed bag, and then the compressed gas is supplied to the sealed bag body to expand it, and at the same time, the table is lowered from the opening of the pipe. In other words, it is a method of reversing the tube lining material, characterized in that a portion of the tube lining material is pressed to deform the tube lining material into an approximately lying S-shape, and the tube lining material is inverted in sequence inside the pipe. .

      Conventionally, however, there is disclosed a method of connecting a tube lining material, which is a liner, and a guide liner, which is a free liner, with a rope and inverting the guide liner by fluid pressure, thereby inserting the tube lining material and a method of manufacturing the lining material into the guide liner after the inversion. However, since the guide liner and the pipe lining material are not in the same pressure working space, the pipe lining material is tightened in the insertion guide portion of the portion entering the pressure working space, and it is difficult to insert the pipe lining material into the pressure (space) working space.

      In addition, Japanese Patent Application Laid-Open No. 64-42220 discloses a method of softening a thermoplastic (polyethylene, PVC, etc.) member (called a tube lining material in the present invention) into heat and drawing it into a pipeline. As a result, the softened tube lining material was cooled and caught in projections caused by misalignment or the like that occurred in the joints in the pipe line.

      In addition, in Japanese Patent Laid-Open No. 6-262684, hydraulic pressure was applied under the condition that the position before insertion of the pipe line and the pipe lining material was close, so it was necessary to secure the head pressure (height). For example, in a case where the arrangement position of the pipe line and the pipe lining material (before insertion) of the pipe line is far apart, it is necessary to construct a moving passage or the like before inserting the pipe lining material, and also to increase the head pressure (height). To secure it, it is necessary to build a warehouse on the ground.

      The problem to be solved by the present invention is that the guide liner and the pipe lining material is not in the same pressure working space, it is difficult to insert into the pressure working space, and also softened pipe lining as disclosed in Japanese Patent Application Laid-Open No. 64-4220. It is necessary to secure the head pressure (height) even if the ash is cooled and the protrusion is caused by misalignment or the like caused in the joints in the pipeline, and the position before the insertion of the pipeline and the pipe lining material is close, as in JP-A-6-262684. Therefore, it is a problem that needs to build a warehouse on the ground.
