The invention discloses a cast-in-place box culvert formwork supporting frame integral moving type construction method and structure. The method includes the steps that erected box culvert supports (1) are used and jacked through common hydraulic jacks, steel channels (2) are placed below the box culvert supports (1), short steel pipes (3) are inserted in the positions below the steel channels (2), one end of each first steel wire rope (4) is fixed to the proper position of the middle lower portion of an upright in the fourth span in the moving direction of the box culvert supports (1), the other end of each first steel wire rope (4) is fixed to the rear end of a chain block (5), the front end of the chain block (5) is fixed to a front support or a stable construction machine through second steel wire ropes (6), and the supports are pulled by the chain block (5) to slowly move. The box culvert supports of different sections are erected at a time and detached sequentially so that the construction period can be
