Tunnel secondary lining arch concrete horizontal directional roof-rushing construction system

The invention discloses a tunnel secondary lining arch concrete horizontal directional roof rushing construction system which comprises an arch crown pouring device, a plugging device and a visualization device. The vault filling device comprises a supporting frame, a linear driving actuator, a sliding seat, a filling pipe, a rotary driving mechanism and a tension and compression sensor; the linear driving actuator is connected with the sliding seat and can drive the sliding seat to move up and down, the rotary driving mechanism is arranged on the sliding seat, the infusion tube is vertically installed in the rotary driving mechanism and can rotate under driving of the rotary driving mechanism, and the tension and compression sensor is connected to the top end of an action rod of the linear driving actuator. Whether the top end of the infusion tube reaches the top surface of the tunnel or not when the infusion tube is driven by the linear driving actuator to move upwards is judged according to the detection v
