The movable double-track subway tunnel construction platform comprises a bottom shell and a plurality of universal wheels fixedly connected to the bottom of the bottom shell, a workbench is arranged above the bottom shell, a lifting part is arranged between the workbench and the bottom shell, and a plurality of threaded cylinders are rotationally connected to the inner top wall of the bottom shell; a positioning bolt is in threaded connection with the lower half portion in the threaded cylinder and penetrates through the inner bottom wall of the bottom shell, a plurality of electric push rods are fixedly connected to the inner bottom wall of the bottom shell, the output ends of the electric push rods are jointly and fixedly connected with a driving plate, and a linkage part is arranged between the driving plate and the threaded cylinder; and a transmission part is arranged at the upper half part in the bottom shell. The invention relates to the technical field of building engineering construction. It is ensured that the positioning bolts make contact with the ground before the workbench ascends, construction safety is improved, the positioning bolts do not need to be manually rotated any more, and use of operators is facilitated.
