ROAD DRAINAGE DITCH DEVICE
To provide a road drainage ditch device that can solve problems such as inflow of small amounts of soil and sand along with rainwater into a grating, accumulation of the soil and sand at a mouth edge of the grating, and a risk of pedestrians slipping on vegetation exposed on a grating's surface.SOLUTION: A road drainage ditch device is characterized by being formed by: a metal intermediate frame 3 with anti-rust treatment such as zinc plating, comprising a U-shaped drainage ditch body 1, a recess part sitting on an edge step, a top plate supporting a road surface material such as tile or brick, a rising vertical piece provided on the top plate, and a one-sided piece protruding from the recess part; a stainless steel grating; a rainwater channel formed in a space between a rising vertical piece and the one-sided piece through narrow gaps of the stainless steel grating in the inside of the recess part, and in the U-shaped drainage ditch body; and the one-sided piece 7 protruding from the recess part in the metal intermediate frame and formed to slope downward toward the U-shaped drainage ditch body.SELECTED DRAWING: Figure 1
【課題】グレーチング内に雨水と共に微量の土砂が流入して、その口縁に土砂が堆積し、グレーチングの表面に露呈した植木にて歩行者が滑ることも危惧される等の課題を解決する。【解決手段】Ｕ字型排水溝体１と、縁段部に着座する窪部、タイル、レンガ等の道路表面材を支承する天板、天板に設けられた立上り縦片、窪部から張り出した一方側片とで構成された亜鉛メッキ等の防錆処理を施された金属製中間フレーム３と、ステンレス製グレーチングと、該ステンレス製グレーチングの細隙から前記立上り縦片と一方側片との空間及び前記窪部の内側、更にはＵ字型排水溝体に至って形成された雨水流路とで成したことを特徴とする路上排水溝装置に於いて、前記金属製中間フレームの窪部から張り出すと共に、Ｕ字型排水溝体の下方向に向かって傾斜する様形成した一方側片７とで成したことを特徴とする。【選択図】図１TIFF2024089582000001.tif179161
