The invention discloses an annular platform for bridge pier stud construction and a construction method, and belongs to the technical field of auxiliary equipment for building construction. The annular platform comprises a bridge pier stud main body, wherein a first chuck and a second chuck are clamped to the surface of the bridge pier stud main body, and a first clamping groove is formed in the surface, which is close to the second chuck, of the first chuck. In the invention, the first chuck, the second chuck, a first threaded column, a second threaded column, a first construction platform and a second construction platform are designed to be matched with one another, the problem that a construction platform is difficult to build due to factors such as ground geology and terrain can be effectively avoided; when the surface of the bridge pier stud main body is constructed, the supporting height of the first construction platform and the supporting height of the second construction platform can be adjusted according to the operation height, the adjusting process is convenient and fast, the labor hour consumed when a large number of scaffolds and steel pipes are used for installationcan be shortened to a high degree, and the working efficiency of workers is improved.
