PROBLEM TO BE SOLVED: To provide a high-strength tunnel reinforcement structure with simple structure to be easily and quickly assembled.SOLUTION: A tunnel reinforcement structure 2 repairs and reinforces the curved inner wall face of a tunnel 1 formed by bricks 1a. The tunnel reinforcement structure 2 includes a reinforcing plate 3 for covering the curved inner wall face of the tunnel 1, and supporting parts 4 for supporting it. The reinforcing plate 3 consists of a plurality of panels 3u divided along the peripheral direction and the axial direction of the tunnel 1. The panels 3u, 3u adjacent to each other in the peripheral direction of the tunnel 1 are joined to engage with each other at their abutting portions, thus improving the strength of the panels 3u adjacent to each other in the peripheral direction of the tunnel 1 at their joint portions and also improving the accuracy of aligning the panels 3u, 3u to each other. |
