Supporting system for cable bent tower lower cross beam construction

The utility model discloses a supporting system for construction of a lower cross beam of a cable bent tower, a first bracket is pre-buried at the cross beam position of a left tower column and a right tower column as a support, a main distribution beam, a bailey beam and a secondary distribution beam are sequentially arranged on the first bracket from bottom to top, a template is laid on the secondary distribution beam, and the main distribution beam is connected with the bailey beam. Second brackets are further embedded in the positions, located below the first brackets, of the left tower column and the right tower column, the second brackets are provided with arched supporting frames, and the arched supporting frames support the middles of the bailey beams. Compared with a traditional landing steel pipe support method, the operation time for workers to erect the steel pipe support in the air can be effectively shortened, construction safety of the workers is well guaranteed, and industrial injury risks are
