Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings by way of examples of preferred embodiments. It should be noted, however, that the numerous details set forth in the description are merely for the purpose of providing the reader with a thorough understanding of one or more aspects of the present invention, which may be practiced without these specific details.
As shown in figures 1-5, the flow-controllable agricultural land irrigation and drainage dual-purpose system is arranged on a field irrigation and drainage ditch, the field irrigation and drainage ditch is surrounded by plough layer soil and lower layer soil, the lower layer soil comprises a left slope and a right slope which are inclined from outside to inside, and the slope of the slopes is 1%. The system comprises a plurality of first U-shaped grooves and a plurality of second U-shaped grooves, wherein the first U-shaped grooves and the second U-shaped grooves are sequentially arranged along the length direction of a field irrigation and drainage ditch, the lower ends of the first U-shaped grooves and the second U-shaped grooves are embedded in soil at the lower layer, irrigation and drainage components are arranged at two opposite sides of each first U-shaped groove and comprise drainage pipes and irrigation pipes, the drainage pipes penetrate through the side walls of the first U-shaped grooves and are obliquely arranged from the outer sides to the inner sides of the first U-shaped grooves, the included angle between the axial direction of the drainage pipes and the length direction of the field irrigation and drainage ditch is 30 degrees and forms an angle of 30 degrees with the reverse direction of water flow, one end of each drainage pipe, which is positioned in each first U-shaped groove, is provided with a drainage pipe cover, the irrigation pipes are positioned above the drainage pipes and penetrate through the side walls of the first U-shaped grooves, the irrigation pipes are obliquely arranged from the inner sides to the outer sides of the first U-shaped grooves, the included angle between the axial direction of the irrigation pipe and the length direction of the field irrigation and drainage ditch is 30 degrees, and the included angle between the axial direction of the irrigation pipe and the direction of water flow is 30 degrees.
