Climbing type self-lifting tower drum and construction process thereof

The invention discloses a climbing type self-lifting tower drum and a construction technology thereof.According to the construction technology of the climbing type self-lifting tower drum, the climbing type self-lifting tower drum is divided into two sections, self-lifting of the upper tower drum section is achieved in the mode that a climbing device is arranged at the bottom of the upper tower drum section, and the climbing device is installed at a low altitude; the construction difficulty is greatly reduced, the problems of high hoisting cost and difficulty of a self-hoisting construction process in related technologies are solved, meanwhile, the stability in the climbing process is ensured, the construction cost is low, the safety coefficient is high, and even for an ultrahigh tower drum which cannot use special hoisting equipment, the construction cost is low. The self-lifting tower drum can also be constructed by adopting the climbing type construction process provided by the invention, and the actual he
