TBM construction railway tunnel inverted arch precast block forming device and using method thereof

The invention discloses a TBM construction railway tunnel inverted arch precast block forming device and a using method thereof.The TBM construction railway tunnel inverted arch precast block forming device comprises a first functional mechanism, the first functional mechanism comprises a base, an adjusting component and a limiting component, and two limiting rods are fixedly connected to the position, close to the edge of one side, of the top of the base. In the device, when the device is used, the device can be stably placed at a designated use position through the base, then a limiting worm can be rotated and adjusted, the limiting worm can drive a limiting worm gear to rotate, and then the rotating limiting worm gear can effectively drive a limiting bidirectional threaded rod to rotate; the rotating limiting two-way threaded rod can effectively move and adjust the use position of the push block, under the supporting of the supporting roller and the position limitation of the sliding groove, the first guid
