The utility model discloses a movable continuous support system for shield-overlapped tunnel construction. The continuous support system comprises a position locking and back propulsion device and a plurality of wheel type support trolleys. The wheel type support trolleys can longitudinally move back and forth on steel rails laid in a constructed shield tunnel and are continuously arranged from front to back, and the position locking and back propulsion device is mounted on the back of the last wheel type support trolley; the structures of the wheel type support trolley are identical, a plurality of pushing devices for forwardly pushing the trolleys are mounted between wheel type support trolleys adjacent to one another in the front-back direction, and each two wheel support trolleys adjacent to each other in the front-back direction are integrally assembled by the corresponding pushing device for forwardly pushing the trolleys. The movable continuous support system is reasonable in structure, convenient to i
