PURPOSE: A repair method for a manhole is provided to improve water-tightness between a pipeline and a pipe lining material and to prevent leachate from flowing into a manhole. CONSTITUTION: A repair method for a manhole is as follows. The bottom part of a manhole and the deteriorated layers of the connection parts of the manhole and a pipeline are cut and removed. A lining material is spread on the removed parts. A previously manufactured manhole coffin member(100) is folded and is inserted into the pipeline to partially touch the spread lining material. A pipe lining material is inserted into the pipeline through the manhole coffin member. The pipe lining material is pressed to the inner wall of the pipeline using pneumatic or water pressure. The manhole coffin member is installed on the connection part of the manhole and the pipeline. A manhole lining material is inserted into the manhole. An additional lining material is spread on the boundary part between the manhole lining material and the lining material.
