DITCH COVER DEVICE
To provide a ditch cover device that allows for easy and inexpensive installation of a filter that catches falling objects such as leaves and stones.SOLUTION: A ditch cover device 10 comprises: a ditch cover 20 that plugs the opening of a ditch D, such as a drainage ditch, to allow passage of water; a receiving frame 30 that engages the top edges of both sides of the ditch D in the width direction of the ditch D and places the ditch cover 20 on the ditch D; and a filter 40 that is supported by the receiving frame 30 under the ditch cover 20 to prevent falling objects such as leaves and stones from flowing into the ditch D. The receiving frame 30 includes a pair of support frame portions 31 extending along the ditch D and being supported by each upper edge portion in the width direction of the ditch D and supporting the ditch cover 20, and a plurality of connecting bars 35, 36 that extend in the width direction of the ditch D and connect the pair of support frame portions 31 at a plurality of points in the direction along the ditch D. The plurality of connecting bars 35, 36 supports the filter 40.SELECTED DRAWING: Figure 2
【課題】葉や石のような落下物を受けるフィルタの取付作業性が良好かつコストを低廉に抑えることができる溝蓋装置を提供する。【解決手段】溝蓋装置１０は、排水溝等の溝Ｄの開口部を通水可能に塞ぐ溝蓋２０と、溝Ｄの幅方向の両側の上縁部に係止して溝蓋２０を溝Ｄに設置させる受枠３０と、溝蓋２０の下側にて受枠３０に支持されて葉や石のような落下物を受けて溝Ｄ内に流入するのを防ぐフィルタ４０とを備え、受枠３０は溝Ｄに沿って延びて、溝Ｄの幅方向の各上縁部に支持されるとともに溝蓋２０を支持する一対の支持枠部３１と、溝Ｄの幅方向に延びて溝Ｄに沿う方向の複数箇所で一対の支持枠部３１を連結する複数の連結バー３５，３６とを備え、フィルタ４０を複数の連結バー３５，３６に支持させた。【選択図】図２
