PROBLEM TO BE SOLVED: To make a grating frame body temporarily detachable, while preventing the grating frame body from being stolen and further preventing it from being detached unexpectedly to cause an unexpected accident on a pedestrian.SOLUTION: A road drain ditch device comprises a metallic grating frame body that consists of a constant-length channel-shaped drain ditch body buried under a road surface, and inverted L-shaped right and left edge frames formed to the same length with the channel-shaped drain ditch body, and consisting of right and left upper pieces seated at right and left upper-end opening edges of the U-shaped drain ditch body and right and left inward drooping pieces drooping from the right and left upper pieces, and covers upper-end opening edges of the U-shaped drain ditch body. A plurality of spring-like retaining plates located right below the metallic grading frame body form projection engagement parts at right and left ends and are curved by being raised from a state where they are located right below the metallic grating frame body.SELECTED DRAWING: Figure 1
【課題】一時的にグレーチング枠体を取外すことが出来ると共に、グレーチング枠体の盗難、更には不用意に取外れないようにして、それに伴って生じる歩行者への思わぬ事故に繋がること等への課題を解決する。【解決手段】路面下に埋設される一定長さのＵ字型排水溝体と、該Ｕ字型排水溝体と同一長さに形成されると共に、該Ｕ字型排水溝体の左右上端開口部縁に着座する左右上片及びこの左右上片より各々垂下した左右内向垂下片より成る逆Ｌ字型左右縁枠とより構成されると共に、前記Ｕ字型排水溝体の上端開口部を被覆する金属製グレーチング枠体と、この金属製グレーチング枠体の直下に位置する複数個のバネ性保持板であって、このバネ性保持板は左右端に凸状係合部を形成しており、前記金属製グレーチング枠体の直下に位置した状態から引き上げられることによって湾曲した。【選択図】 図１
