The utility model discloses a backfill soil blocking device for upright column isolation construction. The backfill soil blocking device is characterized by comprising a square barrel body, a pull ring arranged at the top of the square barrel body, a ladder stand arranged on the inner wall and the outer wall of one face of the square barrel body, and a horizontal supporting plate arranged at the bottom of the square barrel body and vertically connected with the inner wall of the square barrel body. According to the utility model, the upright post position after excavation of a foundation can be isolated so as to block backfill soil, so that enough space can be reserved for steel bar binding, die filling and pouring construction of the upright post under the condition that backfill soil is not influenced in the range outside the upright post of the foundation, synchronous construction of the upright post and the backfill soil is realized, and the construction efficiency is improved. And the construction effici
