High-strength corrosion-resistant concrete pipe pile and preparation method thereof

The invention relates to the technical field of concrete pipe piles, in particular to a high-strength corrosion-resistant concrete pipe pile and a preparation method thereof. Comprising the following steps: 1, fully mixing a stone material, a sand material, an admixture, a water reducing agent, cement, an epoxy resin composition and deionized water to obtain a concrete base material; 2, after being cleaned, the reinforcement cage is placed in a zinc phosphate solution to be subjected to dipping modification, and a pretreated reinforcement cage is obtained; and 3, the concrete base material is poured into the pretreated reinforcement cage, film closing, tensioning, centrifuging and steam curing are conducted, and the concrete pipe pile is obtained. The concrete base material is prepared from the following raw material components in parts by weight: 100 to 120 parts of stone, 55 to 60 parts of sand, 20 to 30 parts of admixture, 4 to 6 parts of water reducing agent, 35 to 40 parts of cement, 21 to 24 parts of ep
