Intelligent spraying construction method and device of single-layer lining based on monitoring feedback technique

The invention discloses an intelligent spraying construction method and device of single-layer lining based on a monitoring feedback technique. The device comprises a control system, a monitoring feedback system, a spraying system, a feeding system and a driving system. The monitoring feedback system can monitor and measure the position of the whole spraying construction device and the relative position between a spraying site and the axis of a tunnel and a preset lining surface in real time. Preset lining inner diameter parameters and spraying material parameters are input to the control system, the system can automatically run, and complete lining is formed by three-layer spraying construction. By means of the method and device, intelligent spraying construction can be achieved, the construction precision is high, and the efficiency is high.
