Summary:PROBLEM TO BE SOLVED: To reduce labor and time of installation, in a concrete transverse groove transversely installed on a road having a gradient.SOLUTION: A transverse groove 12 installed on a horizontally constructed backing foundation is made of precast concrete, and is composed of a bottom wall 12c for connecting sidewalls 12a and 12b. Both sidewalls 12a and 12b respectively form a horizontal plane on the top ends, and the ascent side top end of a road is higher than the descent side top end, and has a height difference. Both receiving frames 11a and 11b respectively installed on the top ends of the sidewalls 12a and 12b are made of steel, and comprise stages 11d and 11e respectively inclining according to a road gradient on the inside where the contour is opposed by half-splitting a projection shape, and the inside forms a cavity, and a grating is installed in the stages. 【課題】勾配を備えた道路に横断して設置されるコンクリート製の横断溝であって、設置の手間と時間を軽減させることができるようにする。【解決手段】水平に施工された下地の基礎上に設置される横断溝１２はプレキャストコンクリート製で、側壁１２ａ、１２ｂを連結する底壁１２ｃよりなり、両側壁１２ａ、１２ｂはそれぞれ天端が水平面をなし、道路の上り側の天端が下り側の天端より高く、高低差を有している。側壁１２ａ、１２ｂの天端にそれぞれ取付けられる受枠１１ａ、１１ｂはいずれも鋼製で、輪郭が凸形を半割にして対向する内側にそれぞれ道路勾配に対応して傾斜する段１２ａ、１２ｂを備え、内部が空洞をなして前記段にグレーチングが設置される。【選択図】図４
