Saline-alkali soil water conservancy improvement structure
The invention relates to the technical field of saline-alkali soil improvement, and discloses a saline-alkali soil water conservancy improvement structure which comprises an outer-layer pipeline, an inner-layer pipeline and a fixing component, the outer-layer pipeline is laid underground, an outer-layer spiral groove channel is formed in the outer-layer pipeline in the axial direction of the outer-layer pipeline, and a plurality of outer-layer water seepage holes are evenly formed in the outer-layer spiral groove channel; the inner-layer pipeline is embedded in the inner side of the outer-layer pipeline, a gap is formed between the inner-layer pipeline and the outer-layer pipeline, an inner-layer spiral groove channel is formed in the inner-layer pipeline in the axial direction of the inner-layer pipeline, the inner-layer spiral groove channel and the outer-layer spiral groove channel are arranged in a staggered mode, a plurality of inner-layer water seepage holes are evenly formed in the inner-layer spiral groove channel, and the terminal end of the inner-layer pipeline is connected into a drainage ditch. The fixing component is connected between the end opening of the outer-layer pipeline and the end opening of the inner-layer pipeline so that the inner-layer pipeline can be supported in the outer-layer pipeline, and by means of the saline-alkali soil water conservancy improvement structure, it can be avoided that much silt enters the concealed pipe along with water flow.
本发明涉及盐碱地改良技术领域，公开了一种盐碱地水利改良结构，包括：外层管道、内层管道和固定构件，外层管道铺设于地面之下，外层管道沿其轴向开设有外层螺旋槽道，外层螺旋槽道上均匀开设有多个外层渗水孔，内层管道嵌套于外层管道的内侧，内层管道与外层管道之间具有间隙，内层管道沿其轴向开设有内层螺旋槽道，内层螺旋槽道与外层螺旋槽道错位设置，内层螺旋槽道上均匀开设有多个内层渗水孔，内层管道的终端接入排水沟，固定构件连接于外层管道与内层管道的端口之间，以将内层管道支撑于外层管道内，本公开提供一种盐碱地水利改良结构，能够避免较多的泥沙随着水流进入暗管内。
