The utility model discloses a steel platform for precisely positioning an H-shaped steel column in an underground structure. The H-shaped steel column is a built-in steel column of a steel pile. The steel platform comprises a platform body which is a sealed rectangular frame. The inner size of the rectangular frame is adaptive to the pile diameter of the steel pile. Two horizontally opposite positioning clamps are hinged on the rectangular frame. An H-shaped steel column hoop space adaptive to the position of the H-shaped steel column and the shape of the section is formed between the two horizontally opposite positioning clamps. At least three horizontal fine-adjustment bolt supports are arranged on the outer side wall of the rectangular frame. When the steel platform is used to limit the H-shaped steel column lowered down, the H-shaped steel column does not rotate in a planar manner, and the position precision is easy to ensure. The steel platform is manufactured and installed on the ground, so that the man
