COVER FOR UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To provide a cover for an underground structure, of which a slip prevention function of a cover surface may be recovered without replacing the cover, at a low cost.SOLUTION: In a cover 1 for an underground structure including a cover body 3 and a receiver frame 5 for supporting the cover body 3 in a way that allows opening/closing, the cover body 3 has an irregular surface 20 for slip prevention formed on both front and rear surfaces thereof, and the receiver frame 5 allows the cover body 3 taken out from a support part 28 at a desired time to be turned over, and then returned onto the support part 28. When the front surface of the cover body 3 wears out, the cover body 3 is turned over to expose the irregular surface 20 for slip prevention on the rear side that has not yet worn, thereby recovering the slip prevention function.SELECTED DRAWING: Figure 4
【課題】蓋面のスリップ防止機能を蓋自体の交換によることなく、つまり低コストで回復できる地下構造物用蓋を提供する。【解決手段】蓋本体３と、蓋本体３を開閉可能に支持する受枠５とを備えてなる地下構造物用蓋１において、蓋本体３の表裏両面にスリップ防止用凹凸面２０を形成し、受枠５は、所望時にその支持部２８から取り出した蓋本体３を、表裏面を反転した後、再び支持部２８上に戻せるように構成した。蓋本体３の表面が摩耗したら同蓋本体３の表裏面を反転させて未摩耗の裏側のスリップ防止用凹凸面２０を表側にしてスリップ防止機能を回復させる。【選択図】図４
