Technical Field

[0001] The utility model relates to the technical field of farmland irrigation, in particular to a channel structure used for farmland irrigation. Background Art

[0002] Irrigation canals are waterways that connect irrigation water sources and irrigated land, and transport and distribute water drawn from the water sources to various parts of the irrigation area. Within an irrigation area, irrigation canals are divided into five levels: main canals, branch canals, ditches, agricultural canals, and small ditches according to the size of the controlled area. In irrigation areas with complex terrain and large areas, multiple levels of canals such as main trunks, branch trunks, branches, and ditches can be added. In irrigation areas with smaller areas, the number of canal levels can be reduced.

[0003] The longitudinal and cross-sections of the channel should be designed based on data such as the designed irrigation flow and designed irrigation water level.
