Tunnel inverted arch construction movable formwork

The invention provides a tunnel inverted arch construction movable formwork. The tunnel inverted arch construction movable formwork comprises an arc-shaped side formwork, a central ditch formwork and two beams which are parallel to each other, the two ends of the side formwork are rotatably connected with the ends of the beams respectively, and the two ends of the central ditch formwork are fixedly connected with the middles of the beams respectively; a middle longitudinal beam perpendicular to the beams is arranged above the middles of the beams, and side longitudinal beams perpendicular to the beams are arranged above the two ends of the beams respectively; formwork lifting hydraulic jacks are arranged at the two ends of the middle longitudinal beam, lateral hydraulic jacks for pushing the side formwork are arranged on the outer sides of the side longitudinal beams, side formwork lifting supports are arranged above the middles of the side longitudinal beams, side formwork traction motors are arranged on the side formwork lifting supports, and the side formwork traction motors are connected with the side formwork through chain blocks.
