Processing method for subsequent reinforcement of tower crane foundation

The invention discloses a processing method for subsequent reinforcement of a tower crane foundation. Multiple upright anchor bars are connected into the tower crane foundation in an embedded mode. Each upright anchor bar and a cloth bar are bound. The upright anchor bars and the cloth bars are solidified in poured concrete after being bound. The upright anchor bars and switching feet are solidified by pouring concrete. The cloth bars and the switching feet are also solidified by pouring concrete. By the adoption of the reinforcing method, when a single bolt used for fixation is broken, a tower crane can still be installed and used normally.
