Description

  The present invention is an improved invention relating to an aging sewer pipe and a method for inserting a pipe lining material into a pipe line.

  As a prior art, methods for inserting a pipe lining material into a pipeline are disclosed in Japanese Patent Laid-Open Nos. 1-224232, 64-42220, and Japanese Patent Laid-Open No. 6-262684.

According to the “pipeline repair method” shown in the above-mentioned Japanese Patent Application Laid-Open No. 1-24223, when one end of a liner and a rope is connected to a pre-liner end before reversing, and the pre-liner is reversed and inserted into an old pipe by fluid pressure. At the same time, the rope is pulled in the insertion direction of the pre-liner and the liner is pulled into the inverted pre-liner, and then another pre-liner inside the liner is reversed and inserted by the fluid pressure, and this state is maintained. The pipe repair method is characterized in that the curable resin impregnated in the liner is cured.

“Method and apparatus for laying a new pipe inside an existing pipe” disclosed in Japanese Patent Application Laid-Open No. 64-42220 has a rigidity in which the overall cross-sectional dimension is reduced in proportion to the existing pipe. A method of laying a pipe having a new rigidity in a pipe using a thermoplastic member, the step of heating the thermoplastic member sufficiently to change from a normal rigid state to a flexible state; Inserting the thermoplastic member into an existing pipe in a flexible and reduced size state, and inflating the thermoplastic member drawn into the pipe in a flexible state; A method for laying a pipe having a new rigidity inside an existing pipe characterized by comprising a step of forming a shape-retaining lead tubular inner pipe having rigidity capable of withstanding water pressure and earth pressure It was.

In addition, a “pipe lining material reversal method” disclosed in Japanese Patent Laid-Open No. 6-262684 is a method for reversing a pipe lining material into a pipeline, and includes a sealed bag body that is inflated by supply of compressed gas. After preliminarily arranging in the pipe line, a part of the lining material is inverted and inserted into the pipe line by fluid pressure, and after the lining material gets over the sealed bag body, compressed gas is supplied to the sealed bag body The bar is lowered at the opening of the pipe line and a part of the pipe lining material is pressed by the bar to deform the pipe lining material into a substantially horizontal S-shape. This is a method for reversing a pipe lining material characterized by sequentially reversing the inside of the pipe.

However, conventionally, a pipe lining material, which is a liner, and a guide liner, which is a pre-liner, are connected to a rope, the guide liner is inverted by fluid pressure, and the pipe lining material and the manufacturing method thereof are inverted in the guide liner. However, since the guide liner and the pipe lining material are not in the same pressure acting space, the pipe lining material is squeezed by the insertion guide portion of the portion that enters the pressure acting space, and pressure (space ) It was difficult to insert the pipe lining material into the working space.

  Japanese Patent Application Publication No. 64-42220 discloses a method of softening a thermoplastic (polyethylene, PVC, etc.) member (referred to as a pipe lining material in the present invention) with heat and drawing it into a pipe. As the pipe lining material is drawn into the pipe line, the softened pipe lining material is cooled and caught by protrusions such as a shift generated in a joint or the like in the pipe line, so that the insertion of the pipe lining material is extremely difficult.

In Japanese Patent Laid-Open No. 6-262684, the water head pressure (height) needs to be secured because the water pressure is applied under the condition that the pipe line and the position before the pipe lining material are inserted are close to each other. For example, if the pipe opening and pipe lining material (before insertion) are distant from each other, a moving lane or the like must be temporarily installed before the pipe lining material is inserted. To secure this, temporary construction such as Yakura was also necessary on the ground.
