System for achieving paddy field water saving and reducing paddy field non-point source pollution based on diving impoundment
The system is characterized in that the system is composed of an underground water impounding structure and an underground water sluice adjusting structure, the underground water impounding structure is located at the tail end of a drainage channel and the downstream tail end of the underground water flowing direction, is buried under the ground surface and is used for intercepting and storing the diving water, and the underground water sluice adjusting structure is used for adjusting the underground water sluice adjusting structure. The at least one underground water sluice adjusting structure is arranged in the underground water impounding structure, the upper end of the underground water sluice adjusting structure is located above the ground surface, operation is facilitated, the lower end of the underground water sluice adjusting structure is located below the ground surface, and a water inlet is communicated with the water outlet end of the underground water impounding structure. A water outlet of the underground water sluice adjusting structure communicates with the drainage channel and is used for adjusting the underground water level and preventing secondary salinization. An underground barrier can be formed to effectively retain and utilize originally lost underground return water, the purpose of retaining or draining underground diving water is achieved, and the utilization rate of irrigation water is increased.
本发明是一种基于拦蓄潜水实现水田节水并减少水田面源污染的系统，其特点是：它由地下水拦蓄结构和地下水闸调节结构组成，所述地下水拦蓄结构位于排水渠道末端及地下水流向的下游末端、埋设于地表以下，用于拦截和蓄纳潜水，至少一个所述地下水闸调节结构置于所述地下水拦蓄结构内，所述地下水闸调节结构的上端位于地表以上，利于操作，所述地下水闸调节结构的下端位于地表以下、且进水口与地下水拦蓄结构的出水端连通，地下水闸调节结构的出水口与排水渠道连通，用于调节地下水位，防止次生盐渍化产生。其能够构成地下屏障拦有效地拦蓄利用原本流失的地下回归水，达到了拦蓄或排泄地下潜水的目的，提高了灌溉水利用率。
