TUNNEL FIREPROOF STRUCTURE AND ITS CONSTRUCTION METHOD
To prevent the decrease of fire resistance performance of tunnel fireproof structure.SOLUTION: A tunnel fireproof structure 100 of a tunnel 1 comprises fibrous fireproof materials 20 provided along segments 10 of the tunnel 1 and plate members 30 each provided between the fibrous fireproof material 20 and the segment 10 and covering an outer periphery of the fibrous fireproof material 20. The plate member 30 has grooves 32 facing the segment 10 and extending in a circumferential direction of the tunnel 1.SELECTED DRAWING: Figure 3
【課題】トンネルの耐火構造の耐火性能の低下を防止する。【解決手段】トンネル１の耐火構造１００は、トンネル１のセグメント１０に沿って設けられる繊維系耐火材２０と、繊維系耐火材２０とセグメント１０との間に設けられ、繊維系耐火材２０の外周を覆う板部材３０と、を備え、板部材３０は、セグメント１０と対向しトンネル１の周方向に延びる溝３２を有する。【選択図】図３
