Concrete filled steel tubular column construction method

The invention relates to the technical field of structural engineering and construction, and in particular relates to a concrete filled steel tubular column construction method. The method comprises the following steps: 1, preparing self-compacting concrete and installing a steel pipe column; 2, casting the prepared self-compacting concrete from the top of the steel pipe column, performing auxiliary vibration during casting by adopting a high-frequency vibrating tube of at least 9m, and performing auxiliary vibration once while casting the concrete layer of 2m thick each time. According to themethod disclosed by the invention, the self-compacting concrete is adopted, due to relatively high liquidity, the steel pipe is filled with the concrete naturally, thereby achieving the compacting aim. Meanwhile, auxiliary vibration is performed by adopting the high-frequency vibrating tube. Since the steel pipe column is relatively long, high-dropping concrete casting can be realized; meanwhile,auxiliary vibration is pe
