A chemical resistant construction method of an underground structure is provided to restrain the formation of cracks by contraction and expansion of a structure and to have excellent chemical resistance to harmful gas. A chemical resistant construction method of an underground structure comprises a pretreatment step(S10) for removing impurities and pre-treating the surface of a concrete structure, a primer layer coating step(S20) for coating a wet type epoxy primer layer on the surface of the concrete structure, a resin layer coating step(S30) for piling a first epoxy resin layer composed of soft epoxy resin on the wet type epoxy primer layer, a reinforcement step(S40) for piling a glass fiber layer on the first epoxy resin layer, an impregnation step(S50) for piling a second epoxy resin layer composed of soft epoxy resin on the glass fiber layer and impregnating the glass fiber layer between the first epoxy resin layer and the second epoxy layer, and a surface treatment step(S60) for finishing by surfacing the second epoxy resin layer. |
