Abstract

The invention relates to a construction method of chemical-resistant underground structures, which comprises: a pretreatment step, in which foreign materials on the surface of a concrete structure are removed; a primer layer coating step, in which a wet epoxy primer layer is coated over the surface of the concrete structure; a resin layer coating step, in which a first epoxy resin layer made out of a soft epoxy resin is laminated and coated over the primer layer; a reinforcement step, in which a glass fiber layer is laminated over the epoxy resin layer; an impregnation step, in which a second epoxy resin layer made out of a soft epoxy resin is impregnated over the glass fiber layer to impregnate the first and second epoxy resin layers on the glass fiber layer; and a surface treatment step, in which the second epoxy resin layer is subjected to surface treatment for finishing the construction.  In an embodiment of the invention, an FRP process using an epoxy resin and glass fiber is applied to secure the chemical-protection or chemical-resistance property while avoiding adhesion deterioration, such that the corrosion of underground structures due to toxic chemical gases can be prevented in a most effective way, the lifespan of an underground concrete structure can be increased by improving weather resistance thereof, and the underground structures exhibit an excellent adhesion force even in a wet environment.
