PURPOSE:To make it possible to finish lining work in a short time by a method wherein liquid, the specific gravity of which is larger than that of reactive curing type resin liquid, is poured in the branch pipe in a pipeline and the reactive curing type resin liquid is thermally cured by heating lining material and, at the same time, the reactive curing type resin liquid is removed from the neighborhood of the surface of the large specific gravity liquid. CONSTITUTION:Lining material 2 consisting of reactive curing type resin liquid 3-impregnated fiber layer 6 and airtight layer 7, which is formed onto the inner surface of the fiber layer 6 is pulled in a pipeline 1 and fixed by pressure to the inner surface of the pipeline 1 by being applied with fluid pressure therein and expanded. Under the state that the lining material 2 is kept on being fixed by pressure to the pipeline 1 through the application of fluid pressure in the lining material 2, liquid 8, the specific gravity of which is larger than that of the reactive curing type resin liquid 3, is poured in a branch pipe 4 from its terminal. Under the condition just mentioned above, the reactive curing type resin liquid is thermally cured by feeding hating fluid in the lining material 2. By being heated, the reactive curing type resin liquid 3 flows through a branch part in the branch pipe 4. The reactive curing type resin liquid 3 flowing in the branch pipe 4 turns into small particles 3', floats in large specific gravity liquid 8, comes up and gathers in the neighborhood of the surface of the large specific gravity liquid 8. |
