[0002] In order to prevent water leakage in the tunnel during construction, waterproofing membranes are usually laid on the inner wall of the tunnel after initial support. The inner wall of the tunnel usually includes an arc segment and straight segments on both sides of the arc segment. For the laying of the straight segment, it is only necessary to lay it directly in the depth direction of the tunnel, while for the laying of the arc segment, the waterproofing membrane needs to be laid along the trajectory of the arc segment of the inner wall of the tunnel.
