description The invention relates to a construction method of a double-limb thin-wall pier of a bridge and mainly aims at solving the problem of slow construction speed in prior construction of the two-limb thin-wall pier of the bridge. The method comprises the following steps of: pier body reinforcement installation: wherein, the root part of the pier body main reinforcement extends into a cap part, straightthread rolling is carried out on a connecting end of the main reinforcement in a ground processing site by using a heading machine, a sleeve is connected with the threaded connecting end; rollover formwork assembly: wherein, the formworks is raised by using a tower crane, and the horizontal joint and vertical joint of the internal and external formworks are made into flat joints. Rubber stop grout is filled during installation; installation of internal and external operation platforms and a protection system; pier body concrete is lifted and put into the formworks, manual vibration is carriedout by using a plug-in vi
