Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to a U-shaped channel structure for farmland water conservancy irrigation. Background Art

[0002] The U-shaped channel for agricultural water conservancy irrigation is a common irrigation engineering structure. Its main feature is the U-shaped cross-section. The U-shaped channel is usually made of concrete or brick and stone, and has high impermeability and stability. Compared with the traditional trapezoidal channel, the design of the U-shaped channel can effectively reduce the friction loss of water flow, improve water delivery efficiency, and reduce the floor space.

[0003] A Chinese patent discloses a U-shaped channel structure for farmland irrigation (publication number: CN214573803U). When in use, the device is connected by inserting a fastening screw into a circular through-hole of another U-shaped plate, and then using a nut to fix the fastening screw to the connecting block bolt, so that the two U-shaped plates are tightly connected. This eliminates the need to use additional concrete to seal the gap between the two plates during installation, thereby shortening the construction period. However, the above device still has the following defects:

[0004] When the water upstream of the channel carries sediment, especially during the rainy season when soil loss is more serious, the long-term accumulation of sediment will occupy the effective water-passing section of the channel, reducing the water flow channel, thereby reducing the water delivery efficiency. Cleaning the sediment in the channel is more troublesome. Therefore, a U-shaped channel structure for farmland water conservancy irrigation is proposed to solve the above problems.
