一种侧向农田排水沟及其构建方法
摘要：
本发明涉及一种排水沟，特别涉及一种侧向农田排水沟及其构建方法。包括沟壁和沟底，所述沟壁由上面层和复合层构成，所述复合层设置在所述上面层的下方，所述上面层为普通混凝土不透水层，所述复合层由复合层Ⅰ和复合层Ⅱ构成，所述复合层Ⅰ与复合层Ⅱ在沟壁长度方向互相间隔设置，所述复合层Ⅰ为无砂混凝土透水层，所述复合层Ⅱ为普通混凝土不透水层，所述沟底为普通混凝土不透水层。本发明提出的一种侧向农田排水沟及其构建方法，既能保证农田的排涝、排渍功能，又具有沟体中水分回灌的效果。
摘要（英）：

The invention relates to a drainage ditch, in particular to a lateral farmland drainage ditch and a constructing method of the lateral farmland drainage ditch. The lateral farmland drainage ditch comprises a ditch wall and a ditch bottom, wherein the ditch wall is composed of an upper face layer and composite layers, the composite layers are arranged below the upper face layer, the upper face layer is a common concrete water-impervious layer, the composite layers are composed of the composite layer I and the composite layer II, the composite layer I and the composite layer II are arranged in a spaced mode in the length direction of the ditch wall, the composite layer I is a sand-free concrete water-pervious layer, the composite layer II is a common concrete water-impervious layer, and the ditch bottom is a common concrete water-impervious layer. Due to the lateral farmland drainage ditch and the constructing method of the lateral farmland drainage ditch, the flood drainage function and the subsurface water control function of farmland can be guaranteed, and the recharge effect of water in the ditch body can also be achieved.
