PROBLEM TO BE SOLVED: To provide a free drain side ditch which has a precast bottom slab used for a gate-shaped side ditch and in which adjustment concrete is post-cast as needed.SOLUTION: Straight streak grooves 5A are formed along an inner wall surface throughout the lengths of both corner parts of an inner bottom of a side ditch body 3 assembled from a gate-shaped side ditch 2 and a bottom slab 1. In free gradient construction, a vertical plane adhesion area is increased, and adhesion and grip to the whole post-cast adjustment concrete are stabilized and improved by a trapezoidal cross-section of the streak groove 5A. In forward gradient construction without post-cast adjustment concrete placing, a water passage cross-section is formed including the streak grooves 5A at both corners of the inner bottom surface.
【課題】門形側溝にプレキャスト底版を用い、必要に応じ調整コンクリートをあと打ちする自由排水側溝を提供する。【解決手段】門形側溝２と底版１とで組立てる側溝本体３の内底両隅角部の全長にわたり、直線の条溝５Ａを内壁面沿いに形成し、自由勾配施工においては垂直面付着面積の増加および条溝５Ａの台形断面によってあと打ち調整コンクリート全体との付着とグリップを安定向上させるものである。あと打ち調整コンクリート打の無い順勾配施工においては、内底面両隅角の条溝５Ａも含めて通水断面を形成するものである【選択図】図１
