The invention provides an inner working platform for rapid construction of a bridge pier and a construction method using the inner working platform. The inner working platform comprises at least one unit module which is overlapped vertically, wherein each unit module comprises a steel structure framework, a fixed platform, movable frameworks, a movable platform, stairs and protection guardrails, wherein each steel structure framework is formed by welding structural steel; the steel structure framework of each unit module is of a two-layered structure; fixing holes are correspondingly formed in the top and the bottom of each steel structure framework; the steel structure frameworks of two layers of adjacent overlapped unit modules penetrate through the fixing holes to be connected by plugs or bolts; each fixed platform is flatly laid above each layer of structure of the corresponding steel structure framework; the movable frameworks are movably connected with the two sides of the corresponding steel structure framework by plugs; each to two sides of each layer of structure is movably connected with one movable framework; the movable platforms are flatly laid on the movable frameworks; the stairs are connected between the two layers of structures of the steel structure frameworks; the protection guardrails are arranged at the peripheries of the stairs. With the adoption of the inner working platform, the construction efficiency and the construction quality can be effectively improved.
