The invention discloses a strong-support elliptical column. The strong-support elliptical column comprises a pipe column, a column bottom plate and a sealing plate, the column bottom plate is arrangedat the bottom of the pipe column, and the sealing plate is arranged at the top of the pipe column, wherein the interior of the pipe column is provided with a set of partition plates and a set of longitudinal stiffening plates, the partition plates are distributed in an inner cavity of the pipe column, the longitudinal stiffening plates are arranged to be perpendicular to the partition plates andarranged on the partition plates in penetrating and inserted modes, and the partition plates are matched with the pipe column. According to the strong-support elliptical column, the whole structure ofthe elliptical column is optimized, the strong-support elliptical column is simple in structure and reasonable in design, the bottom plate is arranged at the bottom of the pipe column, the partitionplates and the longitudinal stiffening plates are arranged inside the pipe column, and thus the supporting bearing performance and structural stability of the elliptical column structure are greatly improved; and the invention further relates to a assembly and welding technology of the elliptical column, machining precision is greatly improved, the machining quality of the product is ensured, andthe safety of the elliptical column during later use is further ensured.
