The invention discloses a method for environment-friendly construction of an across-river suspended poured continuous box beam. The construction method comprises a step S1 of adoption of steel pipe column and support method construction for pier top cast-in-place beam section; a step S2 of foundation treatment; a step S3 of support design; a step S4 of support erection; a step S5 of supporting mounting; a step S6 of support pre-pressing; a step S7 of beam bottle formwork; and a step S8 of execution of steel bar and prestress porous channel mounting, concrete spouting and curing, prestress application and porous channel mud jacking and the like in a box beam construction mode. According to the method for environment-friendly construction of the across-river suspended poured continuous box beam, attention is paid in the construction process to understanding design ideas and reinforcing control over each construction link, structural strength of the box beam is reinforced, engineering usability and durability ar
