The grouting type epoxy resin anticorrosion impervious concrete is characterized in that: comprises a Huaqian glue A glue solution, a Huaqian glue B glue solution, rheological state cement, sand and water; the white or yellowish A glue solution is prepared by mixing 60 parts by weight of epoxy resin, 15 parts by weight of emulsifier, 1.5 parts by weight of thickener, 0.5 part by weight of defoamer, 0.5 part by weight of mildewproof agent and 200 parts by weight of water; the brown or light brown B glue solution is prepared by mixing 20 parts by weight of low molecular polyamide curing agent, 3 parts by weight of catalyst, 0.75 part by weight of thickener, 225 parts by weight of vinyl acetate-ethylene copolymer emulsion, 0.5 part by weight of defoamer, 1.25 parts by weight of industrial ammonia water and 525 parts by weight of water; and uniformly mixing 1 part by weight of the glue solution A and 3 parts by weight of the glue solution B to obtain the Huaqian glue. Then, adding 3 parts by weight of water, 12-15 parts by weight of rheological cement and 15-18 parts by weight of sand (the particle size is 0.16-4.75mm) into 1 part by weight of the huaqian glue, mixing and stirring uniformly to obtain the grouting type epoxy resin anti-corrosion and anti-permeability concrete.
6. According to claim 5, the glue solution A is prepared by mixing 60 parts by weight of epoxy resin, 15 parts by weight of emulsifier, 1.5 parts by weight of thickener, 0.5 part by weight of defoamer, 0.5 part by weight of mildewproof agent and 200 parts by weight of water; the glue solution B is prepared by mixing 20 parts by weight of low molecular polyamide curing agent, 3 parts by weight of catalyst, 0.75 part by weight of thickener, 225 parts by weight of vinyl acetate-ethylene copolymer emulsion, 0.5 part by weight of defoamer, 1.25 parts by weight of industrial ammonia water and 525 parts by weight of water; and uniformly mixing 1 part by weight of the glue solution A and 3 parts by weight of the glue solution B to obtain the Huaqian glue. Then, adding 3 parts by weight of water, 12 parts by weight of rheological cement and 18 parts by weight of sand (the particle size is 0.16-4.75mm) into 1 part by weight of the Huaqian glue, mixing and stirring uniformly to obtain the grouting type epoxy resin anti-corrosion and anti-permeability concrete.
