Temporary restraining structure and method for tower beam of spatial four-tower-limb cable bent tower

The invention relates to the technical field of temporary constraint of bridges, in particular to a temporary constraint structure and method for tower beams of a spatial four-tower-limb cable bent tower. Steel beam longitudinal brackets are located on the two transverse sides of a steel beam and located between tower limbs on the two longitudinal sides. The longitudinal temporary constraint structure is arranged between a longitudinal bracket of the steel beam and a longitudinal adjacent tower limb and is used for carrying out longitudinal temporary constraint on the steel beam and the tower limb; the transverse temporary restraining structures are arranged between the steel beams and the adjacent tower limbs on the two transverse sides and used for conducting transverse temporary restraining on the steel beams and the tower limbs. The vertical temporary restraining structure is arranged between the steel beam and the side span cross beam between the two tower limbs on the side span side and between the midd
