DRAINAGE STRUCTURE AND CATCHMENT BASIN
PROBLEM TO BE SOLVED: To effectively prevent an overflow in a confluent part of a longitUdinal draInage groove and a small stage drainage groove.SOLUTION: A drainage structure 1 comprises longitudinal drainage grooves 2a and 2b laid in its inclined direction Y at a pitch along its inclination on slope faces 6a and 6b, small stage drainage grooves 3a and 3b laid in its lengthwise direction X in a small stage 7 and a catchment basin 4 arranged in a confluent part of the longitudinal drainage grooves 2a and 2b and the small stage drainage grooves 3a and 3b and draining inflow water from the upstream side longitudinal drainage groove 2a and the small stage drainage grooves 3a and 3b on both left-right sides to the downstream side longitudinal drainage groove 2b. A basin bottom 42 of the catchment basin 4 is connected to a groove bottom 22b of the downstream side longitudinal drainage groove 2b. A top surface 21 of both sidewalls 20 of the upstream side longitudinal drainage groove 2a is connected to the top end 40 of the catchment basin 4, and a groove bottom 22a of the upstream side longitudinal drainage groove 2a is connected to an upstream side sidewall 41a of the catchment basin 4 while maintaining the pitch along the inclination of the slope faces 6a and 6b.
【課題】縦排水溝および小段排水溝の合流部分における溢水を効果的に防止する。【解決手段】排水構造１は、法面６ａ、６ｂにその傾斜に沿った勾配でその傾斜方向Ｙに敷設された縦排水溝２ａ、２ｂと、小段７にその長さ方向Ｘに敷設された小段排水溝３ａ、３ｂと、縦排水溝２ａ、２ｂと小段排水溝３ａ、３ｂとの合流部分に配置され、上流側の縦排水溝２ａおよび左右両側の小段排水溝３ａ、３ｂからの流入水を下流側の縦排水溝２ｂに排水する集水桝４と、を備える。集水桝４の桝底４２は下流側の縦排水溝２ｂの溝底２２ｂに連結している。上流側の縦排水溝２ａの両側壁２０の頂面２１は集水桝４の天端４０に連結し、上流側の縦排水溝２ａの溝底２２ａは、法面６ａ、６ｂの傾斜に沿った勾配を維持したまま集水桝４の上流側の側壁４１ａに連結している。【選択図】図１
