Self-adaptive anti-clogging irrigation and drainage ditch for hilly and mountainous areas
The invention relates to the field of farmland ditches, and discloses a self-adaptive anti-clogging irrigation and drainage ditch in hilly and mountainous areas, which comprises a ditch body, an overflow weir for blocking a water channel in the ditch body is arranged in the ditch body, a water diversion port is arranged at the bottom of the ditch body, the water diversion port is positioned at the upstream of the overflow weir, and a U-shaped water diversion pipe is mounted at the water diversion port. The opening direction of the U-shaped water diversion pipe is the same as the water flow direction in the ditch body, the overflow weir is provided with a isthmus flow opening, the isthmus flow opening and a pipe opening of the water diversion pipe are oppositely arranged, and the water diversion pipe is provided with a residue filtering mechanism. According to the scheme, the overflow weir raises the water level in the dry season, water diversion of the water diversion port is guaranteed, and farmland irrigation is completed; the drainage function of the ditch in the rainfall flood period is not influenced; the overflow weir structure can be used for sediment deposition to raise the water level and filter water in the dry season, and sediment deposited at the overflow weir in the dry season is washed by using the water flow velocity in the wet season.
本发明涉及农田沟渠领域，公开了一种丘陵山区自适应防淤堵灌排沟渠，包括沟渠本体，沟渠本体内设有封堵沟渠本体内水道的溢流堰，沟渠本体底部设有引水口，引水口位于溢流堰上游，引水口处安装有引水管，引水管为U形，U形引水管的开口朝向与沟渠本体内水流方向相同，溢流堰上设有峡流口，峡流口与引水管的管口相对设置，引水管设有滤渣机构。本方案通过设置溢流堰在枯水期进行抬高水位，保障引水口引水，完成农田灌溉；且不影响沟渠雨洪时期的排水功能；还能利用溢流堰结构在枯水期进行泥沙沉积抬高水位和对水进行过滤，在丰水期利用水流速冲洗枯水期沉积在溢流堰处的泥沙。
