Embodiment Construction

[0025] Attached below figure 1 ~ attached Figure 6 The present invention is further described. .

[0026] 1. The water delivery pipe 2 is laid along the farmland production road in the direction of the vertical farm ditch. In order to meet the anti-freezing requirements, the water delivery pipe 2 is laid 1.5-1.8m below the ground surface, and the slope of the pipeline is 1 / 500-1 / 1000. Install a drainage control valve 7 at the water outlet, set a water supply cock 3 every 30-50m along the water delivery pipe 2, and the outlet of the water supply cock 3 is 0.3-0.5m higher than the farmland ground, which is convenient to connect the hose for crop irrigation. The other end of the water delivery pipe is connected to the irrigation water inlet valve 1, and then connected to the outlet pipe of the irrigation pump station or other water delivery pipe networks. The water pressure of the irrigation water inlet valve 1 is controlled to be about 1-2 MPa.

Abstract

The invention relates to the problem of a concealed conduit system for both irrigation and drainage of a farmland and belongs to the technical field of agricultural water soil engineering. The concealed conduit system for both irrigation and drainage of the farmland comprises a water pipe and a seepage pipe, and is characterized in that: the starting end of the water pipe is connected to an irrigation water inlet valve; the terminating end of the water pipe is connected to a drainage control valve; the gradient of the water pipe along a water flow direction is 1 / 500 to 1 / 1000; the water pipe is paved 1.5 to 1.8m under the ground; a water hydrant is upwards arranged on the water pipe every 30 to 50m; a water absorption tube system is arranged along the horizontal and vertical direction of the water pipe every 10 to 20m; the water absorption tube system comprises a backstop, an inspection well and the seepage pipe, which are sequentially communicated; the backstop is communicated with the water pipe; and the gradient of the seepage pipe along the water flow direction is 1 / 300 to 1 / 600. In the concealed conduit system, a low-pressure pipeline irrigation concealed conduit system and a drainage concealed conduit system are combined, so two functions of one set of pipe net are realized, the density of pipe net buried in the farmland can be effectively reduced, and farmland cultivation and mechanical operation are facilitated.

Description

[0001] technical field [0002] The invention relates to the problem of a dual-purpose concealed pipe system for farmland irrigation and drainage, and belongs to the technical field of agricultural water and soil engineering. Background technique [0003] In the construction of farmland water conservancy projects, in order to adjust the water status of farmland, irrigation and drainage projects must be combined and coordinated with each other, and the two types of projects are indispensable. In recent years, low-pressure pipe irrigation and hidden pipe drainage technologies are often used in order to improve the utilization rate of cultivated land. However, the irrigation pipeline system and the drainage pipeline system are arranged separately to form two independent engineering systems. In this independent arrangement, the pipeline system has simple functions and the field pipeline network is relatively dense. On the one hand, it affects farmland cultivation; on the o...
