According to the self-lifting tower drum and the construction technology thereof, the self-lifting tower drum is divided into two sections, self-lifting of the upper tower drum section is achieved in the mode that the lifting device is arranged at the top of the lower tower drum section, and after the upper tower drum section is lifted, the lifting device is arranged at the top of the lower tower drum section. And the lifting ribs are used as prestressed ribs of the lower tower drum section to perform prestressed tension on the lower tower drum section, so that the construction cost of the tower drum is saved. The tower drum is assembled in a one-time lifting mode, and the overall structure and the construction process are simplified. The actual height of the self-lifting tower drum built by adopting the building process provided by the invention can reach more than 200 meters. 本发明公开了的自提升塔筒及其建造工艺，该自提升塔筒的建造工艺将自提升塔筒设置为两段，并通过在下部塔筒段顶部设置提升装置的方式实现上部塔筒段的自提升，在对上部塔筒段提升完成之后，利用提升筋作为下部塔筒段的预应力筋对下部塔筒段进行预应力张拉，节约了塔筒的建造成本。采用一
