Reverse-construction-method pool wall formwork structure of rotational flow pool and construction method of rotational flow pool

The invention discloses a reverse-construction-method pool wall formwork structure of a rotational flow pool and a construction method of the rotational flow pool. The reverse-construction-method pool wall formwork structure comprises an inner formwork, an outer formwork and a bottom formwork, the outer formwork is fixed with the outer wall of the rotational flow pool, the inner formwork is fixed with the outer formwork through a split screw, the bottom formwork is arranged at the bottom of the inner formwork and the bottom of the outer formwork, and a pouring cavity for pouring concrete is formed; and a supporting frame is arranged at the bottom of the bottom formwork, the supporting frame is fixed to the next section of unexcavated pool bottom and used for supporting the bottom formwork, and a water stop boss used for pouring the water stop groove is arranged on the bottom formwork. A reverse-construction-method is adopted for downward excavation in a segmentation mode, after excavation is completed, soil n
