To provide the catch drain with the slope that has excellent safety and workability, and can suitably provide the slope.SOLUTION: A catch drain with a slope 1 comprises: irregular shape connection joints 6,6 that connect light-weight pipe bodies 5a to 5d having different vertical widths, and a plurality of the light-weight pipe bodies 5a to 5d having different vertical widths that are connected stepwise from one having a small vertical width in a downward flowing direction through the irregular shape connection joints 6,6, wherein an irregular shape connection joint 6 has a connecting small tube portion 9 disposed so as to be biased toward an upper surface side with respect to a connecting large tube portion 8, as a result, an upper end face of the connecting large tube portion 8 and the upper end face of the connecting small tube portion 9 are continuous, a catch drain body 2 has the upper end face continuous in a downward flow direction, and the catch drain body 2 has a bottom portion having a stepped slope y/x.SELECTED DRAWING: Figure 2
【課題】安全性及び施工性に優れ、好適に勾配を設けることができる勾配付き排水溝の提供。【解決手段】勾配付き排水溝１は、上下幅の異なる軽量管体５ａ〜５ｄを連結する異形接続継手６，６…と、異形接続継手６，６…を介して流下方向に上下幅の小さいものから段階的に連結される上下幅の異なる複数の軽量管体５ａ〜５ｄとを備え、異形接続継手６は、連結大筒部８の上端面と連結小筒部９の上端面とが連続するように、連結大筒部８に対し連結小筒部９が上面側に偏って配置され、排水溝本体２の上端面が流下方向に連続するとともに、排水溝本体２の底部に段状の勾配ｙ／ｘが形成されるようにしている。【選択図】図２
