When the cement solidifies, a reserved cable trough will be left on the top. If multiple cable troughs are required, multiple fixing frames 15 can be installed to facilitate the formation of the cable troughs; When the cable trough is formed, the power supply equipment is stopped, and the N-shaped frame 11 is driven by the motor to move on the slide rail to move out the processed tunnel section. When the distance of the tunnel is short or the staff needs to renovate part of the tunnel and the required template 10 is small, the second electric telescopic cylinder 141 can be started to retract the execution end, and then the motor is used to drive one of the N-shaped frames 11 or multiple N-shaped frames 11 to move. As long as the second electric telescopic cylinder 141 on one N-shaped frame 11 is left to fix the limit rod 131, the second electric telescopic cylinder 141 is started again after the adjustment is completed to clamp the limit rod 131, and then the above work is repeated to process the next part of the tunnel.
