    Abstract: PROBLEM TO BE SOLVED: To provide an exfoliation protective structure of a tunnel or the like, configured to be suitable for repairing an existing tunnel, to be easily constructed at a low cost with a simple configuration, to reinforce a bulkhead such as a lining wall inner surface of the tunnel for preventing exfoliation, to improve heat insulation and heat retention performance of the bulkhead for preventing icicles or frozen dew, to ensure safety of a vehicle traveling in the tunnel, and to effectively prevent water leakage according to water leakage condition of the bulkhead.SOLUTION: An exfoliation protective structure of a tunnel or the like, is formed by fixing a plurality of synthetic resin reinforcing plates 7 to an inner face of a bulkhead 4. The reinforcing plate 7 has a hollow structure formed by arranging synthetic resin reinforcing projections 11 inside. On both sides of the reinforcing plates 7 holding the reinforcing projections 11, synthetic resin liner plates 8, 9 are arranged.
