The invention discloses a double-limb thin-wall high pier tie beam support-free construction method which comprises the steps that after a creeping formwork climbs, the top elevation is located at thebottom elevation of the tie beam, the lower chamfer height of the tie beam is reduced, pier body concrete of the section is poured, and after the concrete reaches a certain strength, a hanging beam at the top of the creeping formwork is dismantled; a tie beam lower chamfer section formwork, a tie beam middle section formwork and a tie beam upper chamfer section formwork are installed respectively, then concrete is poured, and then the tie beam upper chamfer section, the tie beam middle section, the tie beam lower creeping formwork operation platform, the transverse bridge direction connectingbeam, the pier column formwork located on the transverse bridge direction side and the tie beam lower chamfer section formwork are dismantled in sequence. According to the method, the problem of repeated mounting and dismounting caused by the fact that all original pier body templates need to be dismounted during high pier tie beam construction is solved; the pier body construction system and thetie beam construction system achieve the fusion effect, no support is needed in the whole tie beam construction process, meanwhile, a formwork integrated platform in pier body construction is utilized, the effect is guaranteed, and the safety guarantee is greatly improved.
