Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation and impounding, and relates to an irrigation and impounding structure. Background Technique

[0002] Irrigation and impounding is a comprehensive concept of water conservancy engineering technology, aiming to effectively manage and utilize water resources through a series of engineering measures. In an irrigation system, the impounding project plays a crucial role. It can help us better regulate and utilize water resources to meet the needs of farmland irrigation. When irrigation is required for the land, pipeline diversion is needed. During the process of irrigation and impounding, if pipeline diversion cannot be carried out, a series of serious problems will occur.

[0003] The lack of pipeline diversion will lead to the ineffective distribution of water resources to each irrigation area, resulting in insufficient water supply for farmland. This will directly affect the growth and yield of crops, and may even cause the crops to wither due to water shortage, causing significant losses to agricultural production. At the same time, it will also exacerbate the waste of water resources. Therefore, there is an urgent need for an irrigation and impounding structure to solve the above problems.
