Zusammenfassung: | To provide an overflow prevention cover capable of keeping a preferable draining function even when foreign matters accumulate, dispensing with frequent cleaning work, and an installation method thereof.SOLUTION: An overflow prevention cover 10 has a first inclined part 24 having multiple first hole parts 25 and a second inclined part 26 having multiple second hole parts 27. The first hole parts 25 and the second hole parts 27 have first extended parts 28 and second extended parts 29 extended upward, respectively. The overflow prevention cover 10 is installed so that the first inclined part 24 is positioned on an upper slope face 52 side, and the second inclined part 26 is positioned on a lower slope face 54 side, and to cover a drain ditch 40. Thus, foreign matters dropping from the upper slope face 52 accumulate on the first inclined part 24, and accumulation on the second inclined part 26 can be prevented, to thereby keep a draining function. Three-dimensional cross sections of the first hole parts 25 and the second hole parts 27 allow easy scattering of accumulated fallen leaves, dispensing with frequent cleaning work.SELECTED DRAWING: Figure 1
【課題】異物が堆積しても良好な排水機能を保持することができ、頻繁な清掃作業が不要な溢水防止カバー及びその設置方法を提供すること。【解決手段】溢水防止カバー10は、複数の第一孔部25を有する第一傾斜部24と複数の第二孔部27を有する第二傾斜部26を具え、第一孔部25と第二孔部27は、それぞれ、上面側に延出する第一延出部28と第二延出部29を具えている。溢水防止カバー10を第一傾斜部24が上側法面52側に、第二傾斜部26が下側法面54側に位置するように、且つ、排水溝40を覆うようにして設置することにより、上側法面52から転落してくる異物を第一傾斜部24に堆積させ、第二傾斜部26への堆積を防止することができるので、排水機能を保持することができ、第一孔部25と第二孔部27の開口部の断面は立体的なので、堆積した落葉が飛散し易く、頻繁な清掃作業は不要である。【選択図】図1 |
