[0002] The construction of the bottom and the top of the tunnel in tunnel construction adopts the form of separate pouring, which is usually pouring the bottom first and then pouring the top. The inverted arch construction usually adopts arc-shaped formwork construction, which is divided into concrete pouring area a and reinforcing banding area b along the length direction of the tunnel. In order to strengthen the strength of the concrete, the reinforcement is usually pre-buried. When the reinforcement is pre-buried, the high-low combination method is adopted to ensure the bonding strength of the concrete of the inverted arch and the top of the tunnel. Currently, the reinforcement is basically manually bound. During the binding process, there is no height reference, so it is difficult for workers to accurately position the height of the reinforcement. Therefore, it not only takes time and effort to bind the reinforcement, but also causes uneven height, which affects the quality. SUMMARY
