The invention discloses high-strength corrosion-resistant flame-retardant concrete for subway engineering and a preparation method of the high-strength corrosion-resistant flame-retardant concrete, and belongs to the technical field of subway engineering. Comprising 200 to 250 parts of cement, 350 to 500 parts of stones, 200 to 250 parts of mixed sand, 100 to 150 parts of a gel material, 50 to 70 parts of reinforced fibers, 30 to 50 parts of flame-retardant slurry, 60 to 80 parts of an anticorrosive filler, 100 to 150 parts of lightweight aggregate, 10 to 15 parts of a water reducing agent, 5 to 10 parts of a retarder, 20 to 40 parts of an inorganic filler, 10 to 15 parts of an anti-aging agent, 5 to 10 parts of a binder and 250 to 400 parts of water. The flame-retardant slurry comprises the following raw materials in parts by weight: 50-80 parts of epoxy resin, 30-50 parts of rock wool, 10-15 parts of glass wool, 5-10 parts of diammonium hydrogen phosphate, 3-8 parts of zinc oxide, 1-4 parts of urea, 3-6 parts of calcium carbonate and 2-5 parts of a flame retardant. The flame-retardant slurry, the reinforced fibers, the anti-corrosion filler and the inorganic filler are mixed with the cement, the stones, the mixed sand, the gel material and the water to form concrete slurry, and the concrete slurry is effectively combined with the cement, the stones, the mixed sand, the gel material and the water through a plurality of auxiliaries, so that the strength, the corrosion resistance and the flame retardance of the concrete are improved.
